Title: Watch with alarming function of battery lifetime
Inventor: WATANABE KENICHI
IPC: G01R19/165
Filed: 1981-06-22
Abstract: PURPOSE:To ensure the effective use of a battery extending to the end of its life, by switching a timepiece circuit to another battery when the voltage of one of the two batteries drops and at the same time detecting the state of recovery of said battery. CONSTITUTION:If the voltage of a battery B1 lowers less than the set voltage when the battery B1 is selected SL for a power supply of a timepiece circuit CL, this voltage drop is detected by a detecting circuit D to actuate the timers T1 and T3. Then a battery B2 functions as the power supply of the circuit CL just for 30min. When the output of the timer T1 stops, the battery B2 is switched again to the battery B1. At the same time, the timer T2 works. If the voltage of the B1 has no drop less than the set voltage for 5min, it is regarded that the B1 can be used again. Then the timer T3 is reset to secure the original state. In case the B1 drops again less than the set level of voltage within 5min, the T2 is reset by the output of the circuit D. Thus the timer T3 continues the timing. If the battery B1 has no recovery within 24hr, the lifetime of the battery is informed A.

Filed: 1979-07-28
Abstract: PURPOSE:To make possible to install a charge timing with a few pieces of charge (detecting) electrodes by fixing a phase of a charge voltage pulse applied to the charge electrodes.

Abstract: PURPOSE:To simplify a fine adjuster for a thin-type liner, having two plates fitted with each other, by using the fitting part as a hydraulic ram cylinder, feeding hydraulic pressure to the inside, and changing thickness of the linear. CONSTITUTION:Each pressure receiving chamber 2 is installed in a body 1 and a ram cylinder 8 fitted in this chamber is being clamped to a pressure receiving plate 7 which is formed into the same diameter as the body 1. Respective hydraulic chambers 3 installed in and around each of the pressure receiving chambers 2 are interconnected to these pressure receiving chambers 2 through each groove 9. Each cylinder 4 is inserted into these hydraulic chambers 3 and since there is each screw 5 in the one end, it is screwed in each screw chamber 6, and when this screw 5 is screwed thereinto, the cylinder goes forward, thereby feeding an oil in the oil chamber 3 to each pressure receiving chamber 2 through the groove 9. With this oil feed, the ram cylinder 8 moves in an X direction whereby a liner becomes thickened as much as a very small amount, and when inversely the screw 5 is rotated to the reverse, the ram cylinder is retracted and moved to the opposite side to the X direction so that the liner becomes thinned as much as a minute extent. With this constitution, thickness adjustment for the minute extent can be done with a simple device.

Title: Printing head drive controller
Inventor: KOZAI FUMIO
IPC: B41J25/304
Filed: 1986-04-25
Abstract: PURPOSE:To enable the low noise generation of the titled controller, by driving a DC motor by the pulse of which the width or the crest value is large at a starting time. CONSTITUTION:If a positive pulse energization is applied to a DC motor 9 when a link pin 13 is at a position of 0 deg. in rotary angle, a drive gear 10 is rotated counterclockwise and a follower gear 11 is rotated clockwise. Thereby, the link pin 13 is moved to the position of 240 deg. in rotary angle along a guide groove 14. Following the leftward displacement of a link lever 16, a tensile coil spring 6 acts upon a driving lever 5 and a printing head 3 is pressurized onto a platen 2. Because the width of a conducted pulse becomes gradually small from the start of the operation, the rotational frequency of a motor 9 at the end of driving becomes small and the collision noise where the link pin 13 strikes against one end of the guide groove 14 becomes small. Further, if a negative pulse is applied to the DC motor 9 when the link pin 13 is at a position of 240 deg. in rotary angle, the gears 10 and 11 are rotated reversely to each other. The lever 16 is displaced rightward and the printing head 3 is separated from the platen 2. The shock noise at that time when the pin 13 strikes against the other end of the groove 14 becomes small.
