Title: Rotary motion transmitting body
Inventor: TOTSUKA YUKITAKA
IPC: F16H55/38
Filed: 1988-03-08
Abstract: PURPOSE:To reduce power required for starting by fitting the first rotor to one end of an elastic member, and the second rotor to which rotation is transmitted from the first rotor to the other end thereof. CONSTITUTION:A rotary motion transmitting body 10 includes the first rotor 12 fixed to a rotary shaft 11, an elastic member 14, one end of which is fitted to the first rotor 12, and the second rotor 13 fitted to the other end of the elastic member 14, to which the rotary motion of the rotary shaft 11 is transmitted from the rotor 11 through the elastic member 14. At the time of starting a power apparatus, the elastic member 14 is largely displaced by inertia load on the driven shaft side to absorb the inertia load, and as a driven shaft is rotated, the displacement of the elastic member 14 is decreased to make a steady rotation. Accordingly, the inertia load on the driven shaft side at the time of starting is gradually applied to the power apparatus side.

Title: Production of silver powder for powder metallurgy
Inventor: OKUDA AKIHIKO
IPC: B22F9/24
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain silver powder whose particle diameter and bulk are optimum for powder metallurgy by adding an alkali hydroxide soln. to a silver nitrate soln. to form silver oxide, adding a formaldehyde soln. and reducing the silver oxide at a specified temp. SOLUTION: A soln. prepd. by dissolving an alkali hydroxide such as sodium hydroxide in pure water is added to a silver nitrate soln. to form silver oxide. A formaldehyde soln. is added under cooling to <=60 deg.C, the amts. of the alkali hydroxide and formaldehyde are regulated so that a soln. after reduction is adjusted to pH0.1-6 and the objective silver powder for powder metallurgy is obtd. In this case, the amt. of the formaldehyde soln. added is preferably regulated to 1.1-1.5 equiv. based on the amt. of formed silver. The reason why the silver oxide is reduced at <=60 deg.C is that formaldehyde as a reducing agent is effectively utilized at <=60 deg.C and formic acid as a reactional product is used for controlling particle diameter.  Fine silver powder vanishes by dissolution, nucleus-grown powder is formed and silver powder not uniform in particle diameter and fit for powder metallurgy is obtd.

IPC: G11B33/02
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To smoothly move the upper cover of a cassette by providing intermittently operating rack gears at two positions integrally with the cover of the cassette. SOLUTION: Rack gears 2, 5 coupled to a pinion gear 8 to intermittently operate are provided integrally with the upper cover 1 of a cassette. A driving force is transmitted to a pulley 12 via a belt 13 by the rotation of a motor 14, and the gear 8 moves the gear 5 leftward upward. Accordingly, the cam groove 6 formed integrally with the gear 5 is moved together. The cam boss 3 formed integrally with the cover 1 is guided by the movement of the groove 6 according to the bent state of the groove 6 to be raised up, the cover 1 is hence rotated on a pivot 11 and opened. The gear 5 of the intermittent gear is disengaged from the gear 8 soon when the gear 2 integral with the cover 1 is coupled to the gear 8 on the way of the operation, the cover 1 is guided to a cam groove 4 by a cam boss 7 and opened to the opening end.  In the case of closing, the cover 1 is reversely operated to the above operation. Accordingly, even if the cover 1 is closed manually, the cover 1 can be smoothly moved.

Abstract: PURPOSE:To enable high quality printing by a method wherein a plurality of heating resistors, a controlling circuit for controlling a current flowing through the heating resistors with respect to a printing signal, and connecting wirings among these units are formed integrally with and mounted on a heat-resistant insulating resin base having a specified thickness. CONSTITUTION:After heating resistors 30 and required parts such as an operation control IC 31 for the heating resistors 30 are formed integrally with and mounted on a heat-resistant insulating resin base 32, the heat-resistant insulating resin base 32 is closely disposed on a heat radiating plate 33. When a printing pulse is impressed, the heating resistors 30 are controlled for a current flowing therethrough by the operation control IC 31. In this instance, since the thickness of the heat-resistant insulating resin base 32 is set as thin as 0.2mm, the heat radiation properties of the heat radiating plate 33 disposed on the rear side of the heat-resistant insulating resin base 32 are remarkably enhanced. Consequently, even when the printing pulse is continuously impressed, printing bleeding and tailings are hardly caused, and the printing in high quality can be realized.

Abstract: PURPOSE:To have stable changing-over using a simple configuration by allowing the free end of a valve element to move in compliance with deformation of an actuator made of thermo-sensitive alloy generated according to the ambient temp., and thereby performing changeover operation of the valve element. CONSTITUTION:A fluid such as warm water is introduced from an opening 11, and in case the fluid temp. is low, an actuator 22 will not deform but lies in the shape and position as shown by solid lines. Therefore, an opening 13 is blocked by a valve element 14, and openings 11 and 12 are put in communication, and the fluid flows out from the opening 11 to the one 12. In case on the other hand the fluid temp. is over the specified level at which the actuator 22 is put into work, the actuator 22 made of a shape memory alloy will deform from the position by the solid line to the position by the dot and dash line, and the valve element 14 moves round a pin 21 as fulcrum so as to block the opening 12 and also put the opening 13 in communication with the one 11. As a result, the fluid introduced to the opening 11 flows out to the one 13, and not to the opening 12.
