Abstract: PURPOSE:To reduce a running cost and to surely control the life of a device by providing a counter, a novelty discrimination means and a reset control means on a main body side and making the counter zero clear when a photosensitive unit is loaded on the main body and discriminated to be novel after automatic discrimination. CONSTITUTION:The counter 9, the novelty discrimination means 30 and the reset control means 40 are provided on the main body 6 side. In the case that the photosensitive body unit 1 is discriminated to be novel based on the novelty discrimination means 30 and the memory function of a fuse 10 when it is loaded on the main body 6, the counter 9 is made to be zero clear. Simultaneously, the memory thereof is rewritten to one already used. Thus, it can be automatically, quickly and precisely discriminated whether the unit 1 is really novel or not and it can be smoothly used until the prescribed number of printed sheets Ns is attained. Besides, since the fuse 10 in the unit 1 achieves the memory function which cannot be controlled from the outside and it is inexpensive, the running cost is drastically reduced.

Title: Channel selecting system for television receiver
Inventor: DAIKYO TORU
IPC: H04N5/44
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To automatically set to a channel often watched by a viewer and to improve flexibility in the change of reservation by automatically setting a channel selected at the same time on the same day of the last week based on a channel selection history and weekly information. SOLUTION: At around 07:23 on the first Wednesday, if the viewer turns on the power switch of the TV receiver 6 and sets to Channel 4, at the point when three minutes or more passed, a processing device 1 records it as CH data in the storing area of a CH recording memory, corresponding to that time. At around 07:35 on the next Wednesday, if the viewer turns on the power switch of the TV receiver 6, the processing device 1 reads the CH data about 07:30 on the last Wednesday recorded in the CH recording memory 2, and sets to Channel 4 based on the read CH data. Thus, whenever the power switch of the TV receiver is turned on, it is automatically set to the channel usually watched by the viewer in the time zone.

Title: Illumination fixture
Inventor: NAGAO HITOSHI
IPC: F21V31/03
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To certainly discharge water without increasing the over hang of an illumination fixture main body and prevent light leakage and bug entry without providing an executive light shield plate, etc., by interposing a packing between a front face frame mounted on the fixture main body and an external collar. SOLUTION: A packing 3 is provided with a water discharge part 21 and intervened between the internal face of a front face frame 2 and an external collar 5. Thereby the inside of an illumination fixture main body 1 is water-proofed, and the water entering from the back face side in the main body 1, etc., communicates a rise part of the collar 5 or a circumferential edge of the frame 2 through the part 21 of the packing 3 and flows down to the outside. Therefore, water can be discharged certainly without increasing the over hang from a wall face 17 of the main body 1. On the other hand, even if the light in the main body 1 pass through the part 21, light leakage to the outside can be prevented because the front of the part 21 is covered with a circumferential wall part 20 at the circumferential edge of the part 6 or frame 2, and the bug-proof effect can be achieved.  In addition, workability can be improved because there is no need for considering a water discharge hole for construction work of a waterproof packing 16 between the main body 1 and the wall face.

Filed: 1994-12-28
Abstract: PURPOSE: To surely prevent overcharge or undercharge by calculating the rising rate of charging voltage as a parameter and ending the charging operation of a battery based on a charge stop signal sent out from a control circuit for setting a charging time. CONSTITUTION: The control circuit 36 for a charging circuit 35 comprises a microcomputer 45, e.g. a CPU, which sends out a charging voltage control signal (c) to an output voltage control circuit 48 thus controlling the charging voltage. On the other hand, a charging voltage signal (d) of a reference voltage Vst is detected by the output voltage control circuit 48 and sent out to the microcomputer 45. The microcomputer 45 operates the battery charging time and delivers output signals, while counting by means of a built-in timer, to a switching regulator control circuit 38. Upon elapse of the battery charging time, a charge stop signal (e) is sent out to the switching regulator control circuit 38 and the charging circuit 35 is disconnected. With such arrangement, the battery can be protected against overcharge or undercharge under any conditions.
