Title: Electrodeless discharge lamp lighting device
Inventor: KIDO HIROSHI
IPC: H05B41/24
Filed: 1994-06-23
Abstract: PURPOSE:To prevent the starting property of an electrodeless discharge lamp from being impaired even during time-shared dimming control by providing a means for stopping a dimming circuit from being driven when an overcurrent protection circuit is not driven and at the start of the electrodeless discharge lamp. CONSTITUTION:When an electrodeless discharge lamp 7 is removed, an overcurrent flows through a resistance R1, an output Vc of a comparator IC1 reaches H level, and the discharge lamp 7 is turned off. A time constant based on a resistance R17 and a capacitor C21, and a time constant based on a resistance R19 and a capacitor C22 are set at the same value so that an output Vd of the comparator IC2 can be raised to the H level at the same time. Then a transistor Q6 is turned on, the voltage between the gate and source of a transistor Q3 becomes zero, the transistor Q3 is turned off, and a dimming circuit 6 stops being driven. When the discharge lamp 7 is installed thereafter, no overcurrent flows through the resistance R1 and the output Vc of the comparator IC1 is lowered to L level, so the discharge lamp 7 attains a stable full- lighted state after a period of time.

Title: Output buffer circuit
Inventor: SUGIYAMA NOBUYUKI
IPC: H03K17/16
Filed: 1987-06-05
Abstract: PURPOSE:To decrease the peak current by connecting plural MOS transistors(TRs) between an output terminal and a power terminal and making part of the plural MOS TRs conductive when a power voltage VDD and a potential of an output terminal showing a peak in a ground GND current as a buffer starts moving. CONSTITUTION:P-channel MOS TRs QP1, QP2 are connected between the output terminal OUT and the VDD, and N-channel MOS TRs QN1, QN2 are connected between the output terminal OUT and the GND. The peak current of the VDD and GND at an output buffer is large when the potential at the output terminal starts changing from a low to a high level or from a high to a low level and the current flows to the two MOS TRs QP1, QN1. Thus, the peak of the VDD and GND current at the operation of the output buffer is decreased by reducing the size of them.

Title: Measuring instrument for waving shape of disk surface
Inventor: WAKANA SHINICHI
IPC: G11B5/84
Filed: 1988-06-09
Abstract: PURPOSE:To easily and accurately measure the waving shape of the surface by detecting the rotational deflection of a mounting base for the disk and correcting the arithmetic result of a photodetecting element output arithmetic means. CONSTITUTION:A measurement sensor 7 irradiates the disk 1 which is rotated by a power source 3 with the laser light, whose reflected light is photodetected by the photodetecting element of the sensor 7. Then when the disk 1 rotates and a position different from an initial position is irradiated, a rotational deflection detecting means 11 detects the quantity of deflection. The output of the deflection detecting means 11 is applied to a position adjusting means 12 corresponding to the measurement sensor 7 and an output arithmetic means 13. Then the position adjusting means 12 corrects the position of the measurement sensor 7, i.e. the position on the disk 1 irradiated with the light so as to cancel the influence of the deflection of a disk rotating shaft 4. Further, the output arithmetic means 13 corrects a quantity based upon the deflection of the rotating shaft 4 as to the surface waving shape of the disk 1. Consequently, the accurate surface waving shape can be measured.
