Title: Positioning controller
Inventor: YOSHIDA SHUICHI
IPC: G05D3/12
Filed: 1988-05-20
Abstract: PURPOSE:To attain the track following even at a transient follow-up action by making the gain of an amplifier into 1 when for a transfer characteristic of synthesization from a driving circuit to an actuator, the phase lag is zero and a gain is 1, in the low frequency area near the frequency of the eccentricity of an information track. CONSTITUTION:In the comparatively low frequency area near the frequency of the eccentricity of an information track 2, when for the transfer characteristic of the synthesization from a driving circuit 7 to an actuator 8, the phase lag is approximately zero and the gain is approximately 1, the gain of an amplifier 17 is approximately 1, and thus, y=ra is obtained. Consequently, the presumed accuracy of an eccentricity presumed quantity ra is very high, and when ra=y is obtained, y=r is obtained and this must be e=r-y=0. In this connection, the output of a compensating circuit 6 at this time goes to zero, and the compensating circuit 6 has a function such as the security of loop stability, disturbance suppression and the removal of the direct current dislocation of the central position of a data transducer 3 and the central position of an information track 2. Thus, even at the transient follow-up action, the track follow-up can be executed.

Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device with the reduced faults of the initial breakdown voltage of its insulation film, by providing its electrode on its silicon substrate with an oxygen concentration not larger than a specific value via its insulation film with a film thickness not larger than a specific value. SOLUTION: On a silicon substrate 3 with an oxygen concentration not larger than 1×10<18> atoms/cm<3> , an electrode 1 is provided via an insulation film 2 with a film thickness not larger than 100Å. For example, the oxygen concentration in the silicon substrate 3 is made not larger than 1×10<18> atoms/cm<3> in the former ASTM value. The creation of the silicon substrate 3 with such a low oxygen concentration is made possible by adopting an MCZ method wherein a CZ method is performed under the application of a magnetic field.  Therefore, the reduced faults of the initial breakdown voltage of the insulation film 2, the reduced accidental fault of the age-based breakdown of the insulation film 2, the improved life time of the hot carrier of a semiconductor device with the film 2, its suppressed variation and the improved reliability of its gate oxide film are made possible respectively. Further, for the small film thickness of its insulation film, the use of its low power supply voltage and the speed-up its operation are made possible.

Title: Driving system for sweep-type recorder
Inventor: UENO MASAJI
IPC: G01S7/60
Filed: 1978-10-12
Abstract: PURPOSE:To shorten the sweep repetitive cycle and thus to increase the sweep frequency by using the driving motor which can vary the speed and then giving a high-speed revolution for the motor while the recording pen passes through outside the recording region. CONSTITUTION:The oscillation signals transmitted from transmitter 7 are applied to wave transmitter/receiver 8 as well as to control pulse generation circuit 10. At circuit 10 the recording sweep time is delayed by t0 and then tc to produce set pulse Ps and reset pulse Pr respectively based on the transmission signal. Based on these pulses, control pulse (d) featuring continuous time tc is produced to be applied to velocity control circuit 11. Circuit 11 switches the velocity of driving motor 1 featuring continuous time tc into a high-speed revolution. Through such operation, the sweep cycle of recording pen 4 can be shortened to increase the sweep frequency.

Abstract: PURPOSE:To provide a novel can cap material having excellent corrosion resistance in the cored Part of the can cap by the method featuring high-speed production, cost effectiveness and excellent working environment by scoring a steel sheet coated with a thermoplastic resin, then physically press-fixing the resin surface of the scored part within a specific temp. range. CONSTITUTION:The steel sheet subjected to a surface treatment is first coated with the olefinic resin in the state of a coating material contg. a solvent and is then so cored that the coating thickness attains 3 to 200mum. The cored part is thereafter reheated to activate the resin with which the steel sheet is coated to coat the exposed parts of the steel sheet. The scored part is so heated as to attain the m.p. +100 deg.C range from the softening point of the thermoplastic resin at this time or the resin surface of the scored part is physically press-fixed right after the heating. As a result, the scored part is closed by the resin and the corrosion resistance is improved. In addition, the productivity is improved by the improved working environment.

Title: Variable capacity turbine
Inventor: YAMAGUCHI KOJI
IPC: F01D17/16
Filed: 1986-05-30
Abstract: PURPOSE:To prevent resistance loss with respect to fluid from increasing, by selecting the rate between the vane widthwise dimension and the tangential dimension of the part in which each stationary vane and the associated movable vane overlap with each other when a nozzle falls in a narrowest condition, in a specified range. CONSTITUTION:When a nozzle is formed in the part in which the leading end part of a stationary vane 29 and the trailing end part of a movable vane 34 overlaps with each other, if the dimensions of the overlapping part are excessive along with the stream line, the resistance loss increases to lower the efficiency of inflow. If it is short, the rectifying effect is lost to increase the loss of inflow. Accordingly, the rate of the dimension (1) of the overlapping part with respect to the widthwise dimension of the nozzle part is selected to be in a range from 20 to 60 %, it is possible to obtain a high efficiency.

IPC: H01L29/78
Filed: 1988-05-23
Abstract: PURPOSE:To eliminate the contamination due to an organic substance, sodium or the like by a method wherein a chemical washing process is eliminated before an SiO2 film is formed and the surface of an epitaxial growth layer is not exposed to the air. CONSTITUTION:In a first vacuum tank whose background pressure is 1X10<-4> Pascal or lower when a gas is not introduced, a high-resistance epitaxial growth layer 4 whose film thickness is nearly identical to or lower than a film thickness of a desired oxide film 3 is formed at a substrate temperature of 850 deg.C or lower. A substrate 1 is transferred to the first vacuum tank which has been used to form the growth layer 4 or to a second vacuum tank whose background pressure is nearly identical to or lower than that of the first vacuum tank. When hydrogen and oxygen are supplied onto the substrate 1 at a temperature of the substrate 1 of 1000 deg.C or lower under a definite operating condition, the growth layer 4 is oxidized and a gate oxide film 5 is formed. By this setup, the contamination due to an organic substance, sodium or the like can be eliminated.

Title: Spin development method
Inventor: YAMADA YOSHIAKI
IPC: H01L21/30
Filed: 1989-05-18
Abstract: PURPOSE:To form a uniform pattern by conducting a developing step of dropping developer of low concentration to a main surface while rotating a board at a low speed, and a developing step of dropping developer of standard concentration while rotating it at a reference speed. CONSTITUTION:In a first developing step, developer 2 diluted to 0.01 of normality is dropped on a rotating glass board while rotating a board 1, for example, at 150rpm. After 10 seconds are elapsed, in a second developing step, the rotating speed is raised to 450rpm, developer 2 of 0.20 of normality is dropped, and it is further developed for 70sec. Since the surface of the board is already covered with the developer 2 of 0.01 of normality and the affinity of the surface of the board 1 with the developer 2 is remarkably increased, the pulsating flow of the developer 2 when the developer 2 of 0.2 of normality is dropped is extremely reduced.
