Title: Optical pickup position detector
Inventor: OHIRA YORIAKI
IPC: G11B7/085
Filed: 1989-06-30
Abstract: PURPOSE:To eliminate necessity for another light source, to reduce the cost of parts and simultaneously, to eliminate a change with the passage of time caused by friction by detecting the position of an optical pickup by utilizing the light source of a semiconductor laser provided in the optical pickup. CONSTITUTION:An optical position sensor 8 is irradiated with light to transmit through a plate-shaped half mirror 2 out of laser beams emitted from a semiconductor laser 1. According to the irradiated position of the sensor, the position of the optical pickup in a tracking direction is detected. Namely, since the position of the optical pickup is detected by using the laser beam as a means, non-contact is acquired and there is no resistance when the optical pickup is moved. Thus, there is no change with the passage of time because of the non-contact and it is not necessary to excessively fit the light source since the laser beam of the semiconductor laser is utilized. Further, the cost of the parts is prevented from being increased.

Title: Solid-state image pickup device
Inventor: FURUSAWA TOSHIHIRO
IPC: H04N5/335
Filed: 1981-10-23
Abstract: PURPOSE:To obtain a reproduced picture having a high contrast, by subtracting the register output of a non-output period from the register output of an output period of a charge transfer register to obtain picture signals and therefore offsetting the dark current level voltage. CONSTITUTION:A reset transistor (TR) f2 of an output circuit 62 is turned on in a false transfer period, and a charge storing region 52 is set at constant voltage VDD. Then an output gate electrode is turned on to lead the charge produced by the dark current which is transferred by charge transfer registers 2 and 3 into  the region 52. Thus the voltage V0 of the dark current level is obtained at a  load resistance R2 of a TR e2. This voltage is turned into the output voltage  Vout2 of the circuit 62 and transferred in an optical charge transfer period. By  this period, the optical charge produced at each photoelectric converting element  (a) is transferred through the registers 2 and 3. Then the optical charge is led  into a charge storing region 51 and added with the voltage corresponding to the level V0 and the photoelectric quantity through an output circuit 61. Thus the  output voltage Vout1 is obtained. The voltage Vout2 is subtracted from the voltage Vout1 through a differential amplifier 7. Thus a picture signal Vout3 which  receives no effect of the level V0 is obtained.
