Title: Driving method for printing pulse motor
Inventor: TOIDA AKIKAZU
IPC: B41J29/38
Filed: 1989-10-18
Abstract: PURPOSE:To reduce a printing irregularity without decelerating a printing speed, and to use a pulse motor driving circuit of prior art as it is by selecting the timing of the start command of the motor to be equal to the timing on the way of printing of one line. CONSTITUTION:Since the movement of a platen is most smooth immediately after the start of a pulse motor and before and after the stop of the motor, a pulse motor start command is output when STROBE 2 of a print command of a second block is finished. Thus, since all the blocks are printed in the smallest zone of the moving distance of the platen, the sheet feeding distances L1 - L4 of the first to fourth blocks are substantially equal, and the values are small. As a result, the total sheet feeding distance during one line energization can be reduced by half of the conventional distance. The irregularity in the sheet feeding distance between the blocks is half and the sheet feeding irregularity for causing the color irregularity is reduced by half, thereby remarkably improving the printing quality.

Title: Power unit
Inventor: OBUSE TAKASHI
IPC: H02M7/48
Filed: 1993-10-28
Abstract: PURPOSE:To protect semiconductor elements for converting power constituting an inverter circuit from excessively large currents with a simple protective circuit. CONSTITUTION:A voltage detecting circuit 16 judges whether or not the collector-emitter voltages of transistors 10 and 11 constituting an inverter circuit exceed a reference voltage. Diodes 14 and 15 are respectively provided between the output of a reference voltage generating source 5 and the collectors of the transistors 10 and 11. When an excessively large current flows to the collector-emitter circuits of the transistors 10 and 11, the collector-emitter voltages abruptly rise and the diodes 14 and 15 are set to non-conducting states. As a result, the output of the reference voltage generating source 5 is supplied to control signal limiting circuits 8 and 9 as detecting signals. Upon receiving the detecting signals, the circuits 8 and 9 block or limit the passage of control signals supplied to the basis of the transistors 10 and 11 from control signal generating circuits 6 and 7.

Title: Rectangular lithium secondary battery
Inventor: MORITA TERUYOSHI
IPC: H01M10/05
Filed: 1989-10-18
Abstract: PURPOSE:To enhance the charge and discharge cycle characteristic of a rectangular lithium secondary battery by using lithium loads on both outermost sides of a group of mutually opposed plural electrode plates. CONSTITUTION:Lithium negative electrodes 3 are used on both of the outermost sides of a group of electrode plates of a battery which consist of plural positive electrodes 1 and plural lithium negative electrodes 3 opposite to the plural positive electrodes 1, and an organic electrolyte. When negative electrodes 3 are located on the outermost sides of the group of electrode plates the inside face of each negative electrode 3 is utterly the same as when negative electrodes 3 located at the center portion of the group are opposite to the negative electrodes 1, and therefore the current density is equal in both cases. Since the negative electrodes 1 do not exist on the outside of the negative electrodes 3, no current flows and so there is no problem at all. Generation of dendrite is thus restrained and the charge and discharge cycle characteristic of the battery can be enhanced.
