Provided is a suction catheter including: a catheter main body made of a flexible lengthy body having a lumen inside; a leading-end case portion positioned at a leading-end portion of the catheter main body and including an opening for retrieving an object; and object cutting means partially exposed through the opening and movable in the axial direction within the leading-end case portion. The object cutting means includes a cutting portion exposed through the opening portion, and a power receiving portion driving the cutting portion when receiving power from outside. A leading-end side of the suction catheter is inserted into a blood vessel while a base-end portion of the suction catheter is connected to a suction apparatus. An object sticking to the internal wall of the blood vessel is cut off by operating the object cutting means in the opening of the leading-end case portion while the lumen is vacuumed. The cut-off object is immediately sucked in and retrieved.

A socket for installing a removable memory card in a device is provided having a hook switch mounted on a mainboard of a device and electrically connected thereto, and a sliding tray is insertable into the tray socket from a position extended from the device to make an electrical contact with the tray socket. The sliding tray is alternately retracted and extended by the hook switch when the sliding tray is repeatedly pushed, and a memory socket is installed or formed on an top surface of the sliding tray, for accommodating a memory card and electrically connecting the memory card to the tray socket through the sliding tray.

The present invention relates to a crayon sharpener, which comprises a cavity to which a crayon is to be inserted, a stopper with a plane at one end, a blade which is fixed at an angle corresponding to the cavity and the stopper, and a connecting shaft which has a hole in it for installing in an electric or hand-operated sharpener. This invention can sharpen crayons smoothly and quickly without easily breaking them and the tips of the crayons will not be too sharp. This invention can be used alone or installed in an electric or hand-operated sharpener as a replaceable part to sharpen crayons and is more convenient and economical to use.

The present disclosure illustrates to a fiber module rack system in which a rack includes receiving spaces which each is formed by two frame plates of a base panel. Shell bodies of fiber optic cassettes are mounted in the receiving spaces, and a fiber module is disposed at a front part of the shell body, and a resilient locking member is disposed between the sliding track and at least one side of the shell body, so that the user can quickly and easily dismount the fiber optic cassettes from the rack without using tool.

A wiper seal is less in sliding resistance that is encountered when the seal slides over a raceway surface of a guide rail, better in wear-proof quality, rich in durability, and further easy to steadily install it to a slider. The wiper seal is installed on one end of the slider in a linear motion guide system to wipe away foreign materials adhered on the guide rail. The wiper seal is made of polyester polyurethane foam having a reticular skeleton texture of three-dimensional construction including open-cells therein, the polyester polyurethane foam being squeezed or compressed into from ¼ to 1 / 20 in thickness to form a compact blank of three-dimensional construction having porosity therein. The wiper seal is set to come into sliding contact with the guide rail 1 to exert a positive interference of from 0.1 mm to 0.05 mm.

Rankine cycle apparatus, having closed working medium circulation circuitry, includes a collection mechanism for collecting a working medium leaked or discharged out of the circulation circuitry. The working medium collected via the collection mechanism is stored in an open tank, and the thus-stored liquid-phase working medium is returned to a condenser by means of a return pump.

A mounting and dismounting device for cylindrical bodies comprises a fixing element, a moving element, and a buckling element. The fixing element connects to the moving element on both sides to form a hole. The cylindrical body is then inserted into the hole. A buckling part of the buckling element pivotally connects to the fixing element. One lifts a lifting part for the buckling element to urge against the cylindrical body in the hole. By lifting the lifting part, the cylindrical body can be mounted or dismounted.

A method of manufacturing strain-detecting devices is provided. First, plural cylindrical substrates, each of which has one end closed by a diaphragm, are fixedly placed at predetermined positions of a fixing plate. A positioning marker is previously given to the fixing plate. The fixing plate having the substrates is then assembled into a jig. The jig sustains the substrates so that an outer surface of the diaphragm of each substrate is held at the same level. Through positioning the substrates, all the diaphragms are then positioned in place in a plane direction of the fixing plate with reference to the positioning marker. A strain gage portion is simultaneously formed on each of all the diaphragms. The fixing plate is then disassembled from the jig. In this step, the substrates with the strain gage portions, i.e., strain-detecting devices, are separated from the fixing plate.

A system and method for detecting key actuation in a keyboard assembly, which, in one embodiment, is used as a conductor to electrically communicate with an information appliance. The rows in the keyboard assembly are electrically isolated from one another, and each row contains keys bridging a two-wire bus. Each key has a switch that is closed during key actuation, a diode to polarize the key, and a resistor to provide a resistive load when the switch is closed and the diode is biased with the current flow. Alternatively, each key has a switch that is closed during key actuation, a timer with an output that goes high after a predetermined time period, and a resistor that provides an identifying load when the switch is closed and the output of the timer is high. Other features of the invention include a linear matrix coupled to a row of keys to allow the row to be scanned by sections and individual keys, and a flexible circuit that provides the electrical pathways for the linear matrix.

A four-wheel drive work vehicle includes an engine, a pair of right and left steerable wheels rotatably driven by receiving power from the engine via a differential mechanism, a pair of right and left non-steerable wheels rotatably driven by receiving power from the engine via right and left side clutches and a pivotal cam mechanism for operating a clutch operating member for controlling the side clutch based on a steered displacement of the steerable wheels. The pivotal cam mechanism includes a cam member which is displaced based on the steered displacement and a cam follower member operably associated with the cam member. The clutch operating member is displaced via the pivotal cam mechanism by a predetermined amount in response to a steering operation of the steerable wheels by an angle exceeding a predetermined angle from a straight traveling condition and in association with the displacement of the clutch operating member by the predetermined amount, one side clutch for one of the non-steerable wheels located on the inner side of the vehicle turn is automatically disengaged against an engaging urging force.

A folding wheel chair having a pair of side frames 11 and 12, cross links 13 connecting said side frames each other, and a foldable seat 20 connected to the upper end of the cross links is provided. The seat 20 consists of a front right section 21, a front left section 22, a rear right section 23 and a rear left section 24. The front right and left sections are connected swingably to front edges of said rear right and left sections via a transverse axis X1 at the rear edges, and are connected swingably to the front portions of said cross links respectively via a transverse axis X2, the front right and rear right sections are connected swingably to the right edges of said front left and rear left sections via a longitudinal axis Y1 at the left edges, the rear right and left sections are connected to the cross links via a spring member 30.
