Title: Control method for irradiation of optical memory
Inventor: SASAKI HIROSHI
IPC: G11B7/0055
Filed: 1985-10-16
Abstract: PURPOSE:To record and erase the information at a high speed by using a means to control the quantity of the illumination light. CONSTITUTION:The quantity of the light irradiated to a recording medium 5 is controlled by controlling the quantity of light delivered from a light source 2 through a control part 1. The reflected luminous flux 5B sent from the medium 5 is turned into a luminous flux 4B through a condenser lens 4 and then refracted by a half mirror 3 to be supplied to a photodetecting circuit 6 in the form of a luminous flux 3B. The circuit 6 receives the spot of the input luminous flux 3B and detects the recorded signal as an electric signal 6B from the intensity of said spot. The quantity of the illumination light is increased at an early stage of irradiation in a record or erasion mode. Then the quantity of light is reduced gradually by control. Thus the temperature rise up suddenly at the irradiated area of an optical memory. At the same time, this raised up temperature is kept at a constant level over the period of time needed for record or erasion. This may increase the erasing action time.

Title: Ic for battery charger
Inventor: KATO HAJIME
IPC: H02J7/10
Filed: 1990-08-31
Abstract: PURPOSE:To shorten time required for test work by varying the set value of a timer for test mode. CONSTITUTION:Quick charge operation takes place upon start of charging operation, but an initial timer is set and full charge is not detected before elapse of a time set in the initial timer. The initial timer is set at 4min, for example. Full charge is detected subsequently, but if it is not detected a protective timer is set at 130min, for example, in order to stop quick charge operation. The set time is shortened by a factor of 120 for test mode. Consequently, the initial timer is set at 2sec and the protective timer is set at 65sec. Although battery charging operation control can not be carried out accurately with these set times, normal operation of battery control IC can be judged.
