Title: Erasure optical head
Inventor: ITO NOBORU
IPC: G11B7/135
Filed: 1985-03-14
Abstract: PURPOSE:To make the width of an erasure light spot equal to or larger than the width of a recording light spot by arranging a 1/2 wavelength plate between a semiconductor laser light source for erasure and a polarized beam splitter and rotating a deflected face by 90 deg.. CONSTITUTION:The 1/2 wavelength plate 18 performs the action for rotating a deflected face by 90 deg. and is arranged between a deflection beam splitter 2 and a semiconductor laser 6 for erasure. The semiconductor laser 96 for erasure is arranged so as to give the same deflection as the semiconductor laser 5 for recording and reproduction, e.g., the P deflection to the polarized light beam splitter 2. Through the arrangement above, the P deflection irradiated from the laser 6 is changed into the S deflection while its rotating face is rotat ed by 90 deg. through the plate 18. The intensity distribution of the erasure beam 19, however, is an elliptic shape 13a' longer in a direction orthogonal to this paper. The shape of a totally reflecting plane 17 after reflection is an ellipse 13b' whose major axis is toward the track direction and the same shape as the recording beam. In forming the image of the erasure beam on an optical disc 10, the spot 16 becomes equal to the recording spot 15. Thus, remained erasure is prevented.

Abstract: PURPOSE:To permit the smooth rotation of a rotator by using a system in which a pilot control valve is provided to an oil-pressure circuit between the direction switching valve of a rotary motor and two constant-volume oil pressure pumps and converging, throttling, and unloading operations of the constant-volume oil pressure pumps are made. CONSTITUTION:In the rotary oil-pressure circuit of a construction machinery, particularly the circuit using two constant-volume oil pressure pumps 10, a direction switching valve 3 to control the rotation direction of an oil-pressure pump 1 is provided in a pump-driving circuit 4 connecting oil-pressure pumps 11 and 12 with the oil-pressure pump 1 for rotation. A pilot control valve 14 by which detects a change in loading pressure during the rotation driving period and puts the oil-pressure pump 12 into an unloading, throttling, or converting work is provided between the oil-pressure pumps 11 and 12 and the direction switching valve 3. Thus, the amount of pressure oil throttled to a load pipeline 17 can be gradually incrased and such bad influences as the vibration of suspended loads and the rotator, etc., during the rotation period can thus be prevented.

Filed: 1989-03-03
Abstract: PURPOSE:To reduce the irregularity of sensitivity between each photo diode by a method wherein a PN junction, exposed on the substrate surface, of a photo diode diffusion layer is completely covered with a light shielding metal layer, and its aperture part is filled with a transparent conducting film. CONSTITUTION:The edge end 20 of an aperture part of a light shielding metal layer 19 exists in the inside of a PN junction, exposed on the substrate surface, of a photo diode diffusion layer 14. The inside of the aperture is filled with a transparent conducting film 21 constituted of ITO, SnO2, In2O3, etc. The voltage of the film 21 is set at minus several volts, via the light shielding metal layer 19. Thereby, even if difference exists in residual charge trapped in an insulating film on the photo diode diffusion layer, its effect is so neglected that each diffusion layer 14 is made a depletion layer, and storage charge capacity is uniformized. By this constitution, sensitivity irregularity and afterglow of a photo diode caused by residual charge can be reduced.

Title: Semiconductor device manufacturing device
Inventor: NAKAMURA TOMOKO
IPC: H01L21/205
Filed: 1991-03-18
Abstract: PURPOSE:To supply CVD plasma which is stable at a low pressure by generating the plasma from a gaseous starting material by generating an AC electric field in parallel with the principal surface of a wafer and performing vapor-phase plasma deposition by pulling the positive component of the plasma to the principal surface of the wafer by maintaining the wafer at a negative potential. CONSTITUTION:A force is applied to charged particles by means of an AC electric field parallel to the principal surface of a wafer 7 and plasma is produced from a gaseous starting material and, as a result, the density of the material is further increased by the interaction with an AC magnetic field. Since the plasma is generated almost irrespective of a gas pressure, the plasma can be generated in a low-pressure gas. The plasma electric field in a bell jar 1 is nearly uniform in the jar 1 and abruptly decreases near the internal wall of the jar 1 in the direction of the AC electric field. When a bias is applied across to wafer 7 so as to maintain the wager 7 at a negative potential, the positive component of the plasma is pulled in the direction perpendicular to the principal surface of the wafer 7 and reaches and deposits on the surface to form quality film.

Abstract: PURPOSE:To eliminate need for the use of an expensive band pass filter and to prevent the deterioration in an S/M by employing a PLL loop so as to output a signal having a frequency being the sum of a subcarrier frequency without a spurious component and a low band chrominance frequency. CONSTITUTION:A signal of a subcarrier frequency is outputted from an oscillation circuit 21 and a signal of a low band conversion chrominance frequency having an integral number of multiple of a frequency of a horizontal synchronizing signal while being synchronously with the horizontal synchronizing signal is outputted from an oscillation circuit 22. Then an output from a voltage controlled oscillator 23 whose frequency is the sum of a frequency of a subcarrier frequency signal and a low band conversion chrominance frequency and the signal of the subcarrier frequency are given to a balanced modulator 24 and the difference frequency is given to a phase comparator 26 via a low pass filter 25. The phase comparator 26 compares the phase between the output of the oscillation circuit 22 and the output from the low pass filter 25 and controls the voltage controlled oscillator 23 via a low pass filter 27 so as to obtain a signal having a frequency being the sum of the accurate subcarrier frequency and the low band chrominance frequency and gives the resulting signal to a balanced modulator 28, where the signal is subject to low frequency conversion. Thus, the cost is reduced and the deterioration in the S/N is prevented.
