Title: Lithium battery
Inventor: OKAMURA YASUYUKI
IPC: H01M6/14
Filed: 1987-06-08
Abstract: PURPOSE:To make it possible to obtain favorable discharge performance by providing the case side surface of a lithium to be press-applied to the inner surface of a cylindrical can with a vertical groove and partially cut portions. CONSTITUTION:A press-fit lithium 2 has such a structure that a groove portion in the same direction with the axial direction of a cylindrical can 1 side surface or part of it is cut off. By providing the negative electrode lithium 2 with a cut-off portion 11 for example, electrolyte 3 of free condition can be made present in the portion 11, or movement of the electrolyte 3 in a central hollow space to an interface between an positive electrode collector body 6, lithium 2 and separator 4 becomes easier. As a result, favorable discharge performance is obtained without shortening discharge continuation time.

Title: Ink ribbon regenerative pad
Inventor: SHINOHARA YUTAKA
IPC: B41J31/14
Filed: 1990-05-31
Abstract: PURPOSE:To hold a sufficient amount of ink and obtain excellent regeneration capability by using a material composed of a polyvinyl formal. CONSTITUTION:An ink ribbon regenerative pad whose material is composed of a polyvinyl formal is formed of a communicating porous member and is so designed as to recover the printing density of an ink ribbon by a method wherein the pad abuts against the ink ribbon to apply ink held by a capillary force to the ink ribbon. Since the polyvinyl formal has a large pore ratio, it can hold a large amount of ink and has a great effect on the movement of ink. The preferable diameter of pores is 200 - 400 mum or so with respect to ink, which is ordinarily used for an ink ribbon, such as, for example, ink comprising an oleic acid as a main solvent and having a viscosity of 100 - 500 cps or so, and the preferable pore ratio is 85% or 90% or more.

Title: Selecting information transmission system
Inventor: KOBAYASHI GOROU
IPC: H04Q9/16
Filed: 1984-07-11
Abstract: PURPOSE:To transmit selecting information through one transmission line by transmitting (n+1)-sets of serial pulses from a transmission section, using the 1st pulse at the reception side to set the counter initially and counting the succeeding n sets of serial pulses by the counter. CONSTITUTION:The (n+1)-sets of optical pulse signals transmitted to the n-th relay desired to be set from an optical pulse transmitter 10 turn on/off a photodiode 20, where the pulse signal is converted into an electric pulse signal.

Title: Cooling medium compressor for vehicle
Inventor: SAKATA TAKAO
IPC: F04B49/00
Filed: 1978-11-21
Abstract: PURPOSE: To prevent the overload of a compressor by opening a piston valve when the speed of rotation of a rotor exceeds the regular one in order to set a cooling gas medium free directly toward the intake side.  
     CONSTITUTION: As the rotor 7 rotates at high speed, centrifugal force operated upon a ball 29 increases, and the ball 29 is transferred toward the external diameter because a space between a fixed ring 26 and a slide ring 28 is widened against the elastic force of a spring 33. Simultaneously, a pilot valve 30 recedes, which results in the interruption of the connection between holes 45 and 46 owing to the central large diameter portion 30a. The inflow of a high pressure gas to the head of a piston valve 38 is also interrupted, and a hole 40 is opened as the piston valve 38 is restored by the elastic force of a coil spring 39, so that only the cooling gas medium compressed much more than that in a position where a compressing chamber 11a has passed the medium compressing zone is discharged in the final compressing zone. Thus, the overload of the compressor is prevented, and its power consumption is reduced.
