Title: Tracking servo device
Inventor: MACHIDA MASAHIKO
IPC: H04N5/7826
Filed: 1978-05-25
Abstract: PURPOSE: To improve the response characteristics of tracking servo characteristics by controlling the driving of an electrostrictive element to which a magnetic head is fixed, by way of large and small two sets of electrodes.  
     CONSTITUTION: Two sets of electrodes of relatively small electrodes 115B and 116B and large electrodes 115A and 116A are provided to a bimorph plate 11 being an electrostrictive element to which a magnetic head is provided and which moves the magnetic head in the width direction of tracks. When alternating currents are applied to these electrodes 115B, 116B, the plate 11 vibrates at small amplitudes only at the portion sandwiched by the electrodes 115B, 116B and therefore its resonance frequency becomes large and increases the frequency of the alternating current, thus the plate may be vibrated at high periods. If the applied voltage to the electrodes 115A, 116A is controlled according to the comparison of the envelope  signals in both positive and negative directions to be detected by the head vibrating according to these vibrations, the plate 11 curves largely, thus tracking of the head 4 is servo-controlled. Hence, tracking servo control may be accomplished with high response and in a high range by way of the head vibrating at high periods.

Title: Sample-and-hold circuit
Inventor: SHIMIZU HIROMICHI
IPC: H04N5/378
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To satisfy both slew rate and noise characteristic of an S/H circuit. SOLUTION: A current source transistor is connected with a switch transistor controlled by an SHP (SHD) signal for operating a differential circuit generating an output OUT corresponding an input IN and fed with a base current from a constant current source Ics and a variable current source Icsv. The variable current source Icsv varies the current according to a gain regulation value for the AGC circuit at the post-stage of an S/H circuit. When the input IN is a small signal, current of the differential circuit is decreased and higher priority is given to noise suppression than to slew rate. When the input IN is a large signal, current of the differential circuit is increased and slew rate is enhanced.

Title: Thin film forming method
Inventor: HIRASHITA NORIO
IPC: C23C16/52
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a uniform thin film with excellent reproducibility by a method wherein plasma is generated by extracting a part of reaction gas and emission-analyzed and then the quality and thickness of the film are controlled by monitoring based on the results obtained. CONSTITUTION:Gas is introduced in a reaction chamber 1, extracted by means of a capillary 7, introduced in a plasma generating chamber 8, monitored by a vacuum meter to regulate a valve 14, and gas-discharged by applying a high frequency to an electrode 9 from a power supply 10. Light emission 12 through quartz glass 11 is observed using a spectroscope 16 and the result obtained is sent to CPU17. From the data sent, analysis of the percentage of the reaction gas component is made according to the intensity of the emitted light or the intensity ratio. A thin film generation control system 6 is controlled by feeding-back to regulate the gas flux and so on to obtain a proper component ratio while controlling the film thickness. Based on the relation of the intensity of the light emitted to the thickness of the grown film, the thickness of the film is monitored from the integration of such intensity. When the thickness of the film has reached to the preselected level, the inflow of the reaction gas is stopped and the thickness of the film is thus controlled. According to this construction, a uniform thin film with excellent reproducibility can be obtained.

Title: Annealing process of semiconductor substrate
Inventor: HASHIGUCHI TOSHIYA
IPC: H01L21/268
Filed: 1990-03-16
Abstract: PURPOSE:To enable the even annealing effect to be brought about without depending on the impurity concentration of a semiconductor substrate by a method wherein the substrate is irradiated with short wavelength radiation immediately before it is irradiated with long wavelength radiation. CONSTITUTION:A semiconductor substrate during the initial annealing process is irradiated with short wavelength radiation to sufficiently excite carriers for producing free carriers and then irradiated with long wavelength radiation such as lamp annealing process. That is, the excimer laser irradiation 12 of the semiconductor substrate is simultaneously started with the halogen lamp irradiation 11 of the same. At this time, the excimer laser irradiation may be started earlier than the starting time of the halogen lamp irradiation 11. When the semiconductor substrate is irradiated with excimer laser, the surface temperature only is raised to excite the carriers so as to start the halogen lamp irradiation simultaneously with or immediately after the time when the free carriers are produced by the excited carriers. Through these procedures, the semiconductor substrate can be evenly annealed so that the initial temperature of the substrate may be raised without depending on the impurity concentration to bring about the annealing effect.
