The present invention relates to a multi-step operation electrical switch having an elastic conductive plate, which is deformed to establish an electrical contact when a pressing force is applied thereto and is restored to the initial state to break the electrical contact when the pressing force is removed.

According to the present invention, the elastic plate has a plurality of dome portions formed integrally therewith, each of the dome portions bulges in the direction opposite to the direction in which the elastic plate is pressed and is depressed by the pressing force applied thereto. The applied pressing force varies with the dome portions. In order to prevent an electrical contact from being established when no pressing force is applied to the elastic plate, spacer portions are necessary. According to the present invention, inclined spacer portions are provided along the outer peripheries of a first and a second dome portions, respectively.

Therefore, since the pressing force is temporarily reduced when one dome portion is depressed, a click feel can be provided. Since the pressing force varies with the dome portions, a multi-step operation can be achieved. In addition, since the elastic plate has a plurality of dome portions and a plurality of spacer portions formed integrally therewith, the overall size of the switch can be readily miniaturized.

An injection hole, through which refrigerant in gas state or refrigerant in liquid state is injected into a compression chamber of the scroll compressor, is provided on a fixed scroll, and the gas refrigerant injection or the liquid refrigerant injection is selected and carried out according to an operating pressure ratio.

Interior parts for vehicles such as a front pillar garnish having a mounting bracket 32 to which a mounting clip 40 is connected so that the front pillar garnish is mounted to a front pillar. The mounting bracket 32 is formed on the inner side (that faces the front pillar) of the garnish main body 30 and has an inclined guiding portion 70 in its accommodating space 36 so that the flexible portion 46 of the mounting clip 40 inserted into the accommodating space 36 is bent inside the mounting bracket 32 by the inclined guiding portion 70, and the second engaging portion 50 at the distal end of the flexible portion 46 is prevented from contacting the garnish main body 30 by way of the opening 72 of the mounting bracket 32, thus allowing the mounting clip 40 not to be forcibly pressed against the garnish main body 30.

Syringe systems and flow control systems configured to detect information associated with a liquid material are described. The syringe systems may include a syringe body for housing the liquid material and an injector piston for expelling the liquid material out of the syringe through a discharge outlet at a distal end of the syringe body. Components of the syringe, such as an injector piston, may include sensors configured to measure and/or detect a property of the liquid material, such as concentration, pH, or radioactivity. The flow control system may include a pinch valve and a platen arranged about a fluid delivery channel. Flow within the fluid delivery channel may be controlled by increasing (squeezing the fluid delivery channel) or decreasing the distance between the pinch valve and the platen. Components of the flow control system may include detectors configured to detect properties of fluid in the fluid control channel.

A process for producing turbine rotors and other large rotating components of power-generating gas turbine engines using powder metallurgy techniques. The process involves forming a powder of a gamma prime or gamma double prime precipitation-strengthened nickel-based superalloy whose particles are about 0.100 mm in diameter or smaller. The powder is placed in a can and consolidated to produce an essentially fully dense consolidation, which is then hot worked to produce a billet of a size sufficient to form a forging of at least 2300 kg. The billet is forged at a temperature and strain rate to produce a forging with a uniform fine grain of ASTM 10 or finer. Thereafter, the forging may undergo a heat treatment to achieve a desired balance of mechanical properties while retaining a uniform grain size of ASTM 10 or finer.

In an eye drops container, a barrel portion 2 in the form of a flexible hollow cylinder defines a dent portion 7 which can be gripped with two fingers.

A sheet discharging device has a conveying weight for pressing a conveyed sheet to a caterpillar belt. The pressing force of the weight is increased both when the sheet is discharged from the caterpillar belt to a placement tray, and when the sheet is switched back and conveyed to the bottom of the caterpillar belt. The pressing force of the weight is increased concurrently with the driving of a paddle provided at an outlet of the placement tray. The pressing force is increased by a rubber piece provided on a paddle driving shaft that rotates out of phase with the paddle, so as to engage and press the conveying weight at a predetermined time. The device is capable of reliably conveying a wide variety of sheets onto a tray and transferring the conveyed sheets to a predetermined tray position.

Pressing plates press side faces of a roll paper loaded into a roll paper holder unit of the drop-in type, thereby preventing overrun of the roll paper caused by an inertia force from occurring. Each of the pressing plates is urged by two coil springs which are placed respectively on inner and outer circumference sides of the roll paper. The coil spring on the outer circumference side has a higher elasticity than the coil spring on the inner circumference side. According to the configuration, the pressing force of the pressing plates due to the elasticity of the coil springs is gradually reduced in accordance with reduction of a diameter of the roll paper.

A tensioner for maintaining tension in a timing chain or belt comprises a pivotally mounted lever body biased in a direction to increase tension in the chain or belt, and having a built-in, one-way clutch permitting the lever to pivot the tension-increasing direction but blocking pivoting movement in the opposite direction.
