Title: Motor driving circuit
Inventor: ISOMURA TOSHIAKI
IPC: H02P3/14
Filed: 1992-09-16
Abstract: PURPOSE:To provide a motor driving circuit which facilitates a regenerative braking, reduction of heat generation, dealing with a reverse connection of a power supply and reduction of the size. CONSTITUTION:An FET 1 is connected to a motor 2 in series. A thyristor 4 is connected to the motor 2 in parallel. A first delay circuit 5 generates a first delay time which is longer than a time required to turn off the thyristor 4 completely. When an operation switch 3 is closed and a switching signal is turned on, ON/OFF of the FET 1 is controlled through the first delay circuit 5. On the other hand, when the operation switch 3 is opened and the switching signal is turned off, ON/OFF of the FET 1 is controlled through the second delay circuit 6 which generates a second delay time. With this constitution, at the time of start, the FET 1 is turned on after the thyristor 4 is completely turned off by the first delay time and, at the time of stop, the thyristor 4 is turned on after the FET 1 is turned off, so that a power supply short-circuit state between the FET 1 and the thyristor 4 can be avoided.

Title: Printing controller of dot printer
Inventor: HORI FUSAO
IPC: B41J2/30
Filed: 1987-10-29
Abstract: PURPOSE:To improve the whole printing efficiency by determining whether one-step printing or two-step printing on a condition of the mixture of electric energy is to be supplied and electric energy to be consumed. CONSTITUTION:Electric energy is supplied from a power source 5 at fixed periods, and energy accumulated in fixed periods is calculated every time. Accumul-energy at their point of time is compared with consumed energy calculated as the function for all the number of dots of each block of one line to be printed out. It is determined from the result of comparison whether a line concerned should be printed out in one line or in two lines. Accordingly, when the consumption energy for a block to be printed out one before is in a small amount, the residual accumulated energy increases with the result that the probability of one-step printing is high. Thus, the number of times of one-step printing with the same power capacitance is increased for improvement of the whole printing efficiency.

Title: Alkaline storage battery
Inventor: NAKAMURA TOSHIAKI
IPC: H01M4/38
Filed: 1984-12-27
Abstract: PURPOSE:To reduce the generation of hydrogen gas in an alkaline storage battery by covering the surface of a negative electrode active material made of active metal with vinyl polymer film and using the active material with the electrolyte of a caustic alkaline aqueous solution to obtain the negative electrode black mix. CONSTITUTION:The negative electrode black mix in a sealed alkaline storage battery is formed by using a negative electrode active material made of active metal such as zinc and the electrolyte of a caustic alkaline aqueous solution as the essential components. In this case, the surface of the negative electrode active material is covered with the vinyl polymer film whose monomer unit is indicated by an expression (CH2=CR<1>R<2>), (R<1> and R<2> are selected from a hydrogen atom, halogen element, nitrile group, etc.) at a thickness of 0.01 to 70mum. As a result, since the film functions as a protective coat against the caustic alkaline aqueous solution and the dissolution of the negative electrode active material is suppressed, the generation of hydrogen gas can be reduced without mercury and such.
