An individual package of an absorbent article permits a base end of a tape to be bonded with sufficiently large bonding strength without complicating packaging process and increasing manufacturing cost. The absorbent article is wrapped by a package sheet having side edge portions and end edges, and one end edge is overlapped over the other end edge. The package sheet is sealed along the side edge portions, a base end of a tape is fixed on the surface of the package sheet located outside in an overlapping portion, and a free end of the tape extends across one end edge and is releasably adhered on the outer surface of the package sheet adjacent one end edge. The package sheet has a surface, on which the base end of the tape is fixed, the surface being smoothed by a smoothing process.

A speaker device of the present invention roughly comprises a cabinet (1) and a speaker unit (2a). The speaker unit (2a) is attached to an opening portion formed in a front surface of the cabinet (1). The speaker unit (2a) has a back surface frame (3a), a front surface frame (4a), a first magnetic circuit (5a), a second magnetic circuit (6a), an edge (7a), a damper (8a), a diaphragm (9a), a voice coil bobbin (10a), and a voice coil (11a). A non-magnet member (91a) which is a portion of the diaphragm (9a), the first magnetic circuit (5a), and the second magnetic circuit (6a) play a role as a negative stiffness mechanism to suppress an influence of an acoustic stiffness, thereby achieving a small-size speaker device capable of reproducing low-frequency sound.

A test apparatus for measuring the cohesive, adhesive and frictional properties of bulk solids has a bulk solid sample confined between two essentially parallel plates with a single load applied that produces both shear and normal stress and strain to the bulk solid in a manner that nearly uniformly distributes stress throughout the granular solid test region. The apparatus has a close proximity of the plates compared with the length of the plates in the direction of shear, the design of a load hanger to produce a resultant load near the shear plane, the roughening of any surface in contact with the solid that is not intended to have shear on it and involves one-directional movement of the parallel plates with respect to each other and the control of both the direction and magnitude of the applied load relative to the parallel plates. A test method uses the apparatus to measure the unconfined yield strength angle of internal friction and steady state deformation effective angle of internal friction with a single test. A test method uses replacement of the lower part of the test sample with a plate of material that the bulk solid may be required to slip on and measures the friction angle and adhesion of the bulk solid on the plate of material.

The present invention relates to a dental prosthesis, and more particularly, to a screw-engagement type dental prosthesis which enables non-preparation of the natural tooth because it is manufactured by division into two pieces or three pieces, which can be simply installed, and in which the occlusal pressure can be uniformly dispersed. Also, the present invention relates to a method of casting a screw-engagement type dental prosthesis by using a bolt made of carbon or ceramics. Furthermore, a keeper and a body are engaged with each other via a bolt in a state where thin and semi-conical maintaining portions formed on inner inclination surfaces of abutment teeth of both sides with a small preparation are accurately engaged with keys formed on inner inclination surfaces of the keeper and the body in correspondence to the maintaining portions.

A micro electromechanical relay opens and closes an electrical circuit by contact/separation between a fixed contact disposed on a base and a movable contact disposed on an actuator by driving of a movable electrode by electrostatic attraction by application of voltage between a fixed electrode disposed on the base and a movable electrode of the actuator. The actuator comprises a supporting portion disposed on the base, a beam portion extending in a cantilevered manner from the supporting portion, and a movable electrode and a movable contact elastically supported by the beam portion. The beam portion elastically supports, in order from the supporting portion end, the movable electrode and the movable contact. A slit is formed from the side of the supporting portion in the portion of the actuator connecting the beam portion and the movable electrode.

Apparatus, including a diaphragm valve, is provided featuring a valve body, a diaphragm, a pressure ring, and at least one elastomeric member. The valve body may include a circumferential flange. The diaphragm may include a circumferential gasket portion configured to be seated on the circumferential flange so as to form a joint between the valve body and the diaphragm. The pressure ring may include concentric fluctuations, and may be configured to apply a sealing force against the joint so that the concentric fluctuations prevent radial movement of the circumferential gasket portion and the circumferential flange. The elastomeric member may be configured to respond to a compressive force and provide a substantially constant sealing force, transmitted through the pressure ring, regardless of small variations in the thickness or material dimensions of the circumferential gasket portion caused by temperature fluctuation or material flow and age.

A Venturi valve has a Venturi housing with a plunger slidably mounted on a control shaft within the Venturi housing. Sliding movement of the plunger along the control shaft is controlled by a compression spring. A hard stop is fixed to the control shaft to limit the movement of the plunger along the control shaft in order to keep the compression spring from over compression and from a resulting loss of accuracy.

Disclosed is a lens device including a click mechanism of a ring member that is rotated with respect to a lens barrel body, slides in the optical axis direction, has high slidability during a click operation and high durability, and can prevent one-sided abrasion due to the inclination of the ring member. A click mechanism of a first focus ring includes: elastic members for clicking provided at three equally divided positions on the circumference of a front fixed ring of a lens barrel body; and a contact portion that is formed in a central portion of the inner circumferential surface of the first focus ring and comes into contact with a convex portion of the elastic member for clicking. The elastic member for clicking is made of polyacetal with high slidability. Therefore, it is possible to reduce the abrasion of the elastic member for clicking during a click operation.

An endoscopic treatment instrument is provided which includes: a sheath 2 having electrical insulating properties; a pair of arm portions 3A and 3B which are disposed opposite to each other, which protrude and retract with respect to the sheath 2, and which accordingly open and close to thereby hold an object to be treated; a cutting electrode 5 which is protruded from and fixed to the distal end of the sheath 2 and which supplies a high-frequency electric current when it touches the object to be treated.

An electromagnetic actuator of the present invention includes a rotor that has a cylindrical outer peripheral surface and that is capable of rotating within a predetermined angular range, a magnetizing coil, and a yoke that has an arcuate surface facing the outer peripheral surface, a first magnetic-pole part, and a second magnetic-pole part. The first and second magnetic-pole parts generate mutually different magnetic poles by energizing the coil. The rotor includes a magnetized rotor part that defines the outer peripheral surface of the rotor and that is magnetized to have different magnetic poles in a circumferential direction, a driving pin that is not magnetized so as to rotate together with the magnetized rotor part, and a protrusion part that is protruded in a radial direction from the outer peripheral surface of the rotor and that faces the first magnetic-pole part or the second magnetic-pole part while being magnetized to have the same magnetic pole as the outer peripheral surface of the rotor. According to this structure, the rotor includes the protrusion part that is protruded from the outer peripheral surface of the magnetized rotor part and that is magnetized, in addition to the magnetized rotor part and the driving pin that is not magnetized. Therefore, the surface of the rotor that faces the yoke and that exerts a magnetic action is increased, and hence a desired maintaining force and a driving torque can be obtained.
