Filed: 1988-12-16
Abstract: PURPOSE:To accelerate transfer when a small image is transferred to a large paper by driving a scanning means in plural times within one cycle of a paper feeding means and transferring the plural identical toner images on an identical paper. CONSTITUTION:By controlling the driving of a scanner 10 and delaying the commencement of the starting thereof, identical electrostatic latent images are formed continuously to an electrostatic latent image formed on a photosensitive drum 41. Then, on the identical paper which is fed to a transfer position within one cycle of the paper feeding means, the plural identical toner images are transferred. At this time, by arithmetically operating the relation between the size of an original and the size of a copying paper and the relation such as time required for one time of the scan and the return of the scanner 10 or the like with the aid of a CPU, it is recognized that the images are not superposed. Therefore, when the small image is transferred to the large paper, the need that a transfer drum 51 is rotated as many as the numbers of the images is eliminated and the transfer is accelerated.

Title: Charging circuit for secondary battery
Inventor: SEKI NORIKO
IPC: H02J7/10
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To suppress an overcharge quantity by detecting the temperature of a secondary battery or the ambient temperature, setting a regular drop value in accordance with the detected temperature, and in -ΔV control, surely detecting that a battery voltage is dropped by the regular drop value ΔV from a peak value to control a charging current even when the temperature of the battery is high. SOLUTION: In a ΔV value setting circuit 5, the temperature of a battery 3, which is detected by a thermistor 4, is compared with a reference voltage Vref by a comparator C. A regular drop value (ΔV) is set in accordance with the comparison output by a ->=V control circuit 6. Therefore, when rapid charging is performed by the ->=V control, the regular drop value (>=V) of a battery voltage is set an optimal value in accordance with the temperature of the battery 3, thereby being able to avoid overcharging, so that a bad influence such as the lowering of the electric capacity of the battery 3 and the lowering of its cycle life may be prevented.

Title: Semiconductor lead frame
Inventor: DOI HATSUO
IPC: H01L23/50
Filed: 1990-11-22
Abstract: PURPOSE:To prevent poor contact of inner leads and a heat sink by giving a twist to a part of an inner lead. CONSTITUTION:A groove 16 formed in the lower mold 15 of a pair of press molds holds a cut inner lead 8, which is twisted at about 1 deg.C. At this time, the lower right of the rightmost inner lead 8 serves as a support point 17, and its end, that is, free terminal, serves as the effect point so that momentum becomes largest. However, their clamping in contact with the metal mold in the resin sealing step causes leads afloat to rotate reversely by this factor in a horizontal direction and become horizontal. As a result, a zone 18 of slant cross-section is formed in a wide zone A, and the inner lead 8 can be maintained with the gap between a lead frame 1 and a heat sink 5 kept constant in the resin sealing step.

Title: Timer-interlocked electronic volume
Inventor: WATANABE MITSUYUKI
IPC: H03G3/02
Filed: 1987-12-21
Abstract: PURPOSE:To automatically lower the sound volume of an apparatus little by little, and to make a listener go to sleep comfortably by providing a timer and a pulse circuit interlocked with this timer. CONSTITUTION:When a timer start switch 20 is pushed, the timer 13 starts, and simultaneously, the pulse circuit 11 too starts its operation. The time constants of a resistor 14 and a capacitor 15 are adjusted so that the pulse circuit 11 generates a pulse signal 18 at every ten minutes, for instance. When the pulse signal 18 is inputted to a switching transistor(TR) 17 from the pulse circuit 11, the collector and the emitter of the TR 17 are shorted, and while the collector and the emitter are being shorted, it is equivalent to that a sound volume switch 10 is being pushed, and the sound volume goes down. Thus, an input sound source is made to sound at comparatively large sound volume, just after the timer is operated, and the sound volume is lowered little by little, and when the timer runs out, it comes to a quiet sound volume, and the listener can go to sleep comfortably.
