Title: Tracking error detecting device for optical disk player
Inventor: KUSABA TATSUICHI
IPC: G11B7/09
Filed: 1987-02-20
Abstract: PURPOSE:To prevent tracking control from generating a malfunction due to the angular shift of a photodetector from a data pit by using the sum of the differential output of upper two divisions out of 4-divided photodetector and the differential output of the lower two divisions as a tracking error. CONSTITUTION:A laser beam from a laser diode 16 is reflected by the data pit 20 of a disk 21 and detected by 4-divided photodetector PD1. In such a constitution, the upper two divisions A, B of the PD 1 are connected to the positive and inverted terminals +, - of a differential amplifier 12 and the lower two divisions C, D are connected to the positive and inverted input terminals +, - of a differential amplifier 13. The outputs of the differential amplifiers 13, 13 are added and smoothed by an LPF and the smooth signal is used as a tracking error signal 27. Even if the fitting angle of the PD 1 is shifted from the advancing direction of the pit 20, error signals generated when the pit 20 passes the left side, center and right side of the PD 1 become +, 0 and -, so that stable tracking servo can be attained.

Title: Heater discontinuity sensing device
Inventor: SAITO YASUO
IPC: H05B3/00
Filed: 1988-02-23
Abstract: PURPOSE:To sense heater discontinuity at all times during current supply by storing first the initial current value at the connection end of each heater of an electric heating apparatus. CONSTITUTION:When current is supplied to an electric heating apparatus, a memory control part 3 makes synchronous control of an entry part 1 and a memory and control part 3 itself, and the entry part 1 selects a plurality of input amperage values A1-An entry by entry. A converting part 2 makes conversion into digital values D, while the memory and control part 3 stores these digital values of initial value sent one by one and code signals for identification of heaters of the electric heating apparatus. According to the digital value D of the initial value stored, the memory and control part 3 sends to a comparator part 4 a digital reference value Dr in which the allowable variation range of the current values A1-An of the entry by voltage variation is taken into consideration. Thus the digital value D for the amperage value during current supply to the heaters is compared with the digital reference value stored and computed to serve sensing of eventual discontinuity in the electric heaters.

Title: Ccd solid-state image pickup element
Inventor: KOBAYASHI ATSUSHI
IPC: H04N5/335
Filed: 1991-02-08
Abstract: PURPOSE:To prevent a signal charge from leaking between neighboring bits in a first horizontal register at the time of transferring a signal from a vertical register to two horizontal registers in a CCD solid-state image pickup element provided with two horizontal registers. CONSTITUTION:The signal charge is transferred to the first horizontal register by changing the final stage of the vertical register from 'low' to 'high' and from 'high' to 'low' while both two-phase horizontal transfer pulses are 'low', and then, a transfer gate between the horizontal registers is turned into 'high', and the signal charges of every other bits of the first horizontal register are transferred to the bottom of the transfer gate, and after that, only one side of the two-phase horizontal transfer pulses is turned to 'high', and the signal charge is transferred from the bottom of the transfer gate to the second horizontal register. Accordingly, since both the two-phase horizontal transfer pulses are never switched at a time from 'high' to 'low', the signal never leaks between the neighboring bits in the first horizontal register.

Abstract: PURPOSE:To monitor whether a recording medium is usable or not by the output of a means which detects whether a recording medium is loaded or not by providing the means to an input/output device where the recording medium is replaced. CONSTITUTION:Usable state signals (c) and (d) for the recording medium are negative set inputs to monitoring flip-flops 14 and 16 for the replacement of the recording medium, so when the recording medium in some unit is replaced, the recording medium which is already set is taken out and a new recording medium is set; and the recording-medium usable state signal of the corresponding unit is 0 until said recording medium becomes usable. Consequently, the signal of a unit specified by multiplexer 18 to obtain a recording medium replacement monitor signal (g) from output signals of flip-flops 14 and 16 for monitoring the replacement of the recording medium corresponding to said unit. Therefore, when the signal (g) is 1, it is known that the recording medium is replaced in the past at the specified unit.

Abstract: PURPOSE:To generate a short light pulse having short time width by arranging an amplifying region made of a double hetero junction biased forwardly and an absorption region made of a double hetero junction biased reversely on the same plane in a direction for forming a resonator on the same plane. CONSTITUTION:A semiconductor laser is divided into a proton implanted layer 306, an amplifier region 310 and an absorption region 311, and since the regions are electrically separated, the regions 210, 311 can be independently biased. Since the regions 310, 311 are arranged in the direction for forming the resonator on the same plane, a reverse bias electric field is applied to the absorption region to form the abrupt fall of a light pulse to control the pulse width. Since the recovery of the absorption is fast, the external resonator is not necessary, and a wide band width of the semiconductor is effectively utilized to obtain a short pulse having short pulse width.
