Title: Servo lead-in device for focus lens of optical information reader
Inventor: HOSAKA TOSHIHIKO
IPC: G02B7/28
Filed: 1979-12-07
Abstract: PURPOSE: To ensure a steady and assured focus servo-action, by applying the opposite force to a lens according to the moving speed of the lens when the lens exceeds the desired distance or its vicinity.  
     CONSTITUTION: The start signal and the servo error signal A are applied to the lens driving motor 4 via the adder circuit 3 and in the form of the positive phase input. The signal A is also turned into the adverse phase input of the motor 4. In such constitution, the lens is driven toward the recording surface, and the error signal A is supplied. The control signal D is delivered to the comparator 11 at the time point when the desired distance of the lens, i.e., the polarity of the error signal is reversed. The sampling switch is closed by the signal D, and the output B having the pulse duration according to the moving speed of the lens of the comparator 6 is applied to the motor 4 as the opposite force via the differentiating circuit 9 and the diode 10. In this instant, the loop switch 2 is opened by the signal D, and the lens is positioned nearly at the right place due to a low moving speed of the lens. As a result, the lock-in action can be performed smoothly for the servo.

Title: Manufacture of high-integration semiconductor element
Inventor: BOKU EISHIN
IPC: H01L27/10
Filed: 1993-06-29
Abstract: PURPOSE: To increase capacitor capacitance by increasing a surface area of a storage electrode by forming a number of columnar storage electrodes. CONSTITUTION: A number of columnar oxide film patterns 19 are formed by etching an oxide film 15 in a part which is exposed by using an irregular polysilicon layer 17 as a mask and the remaining irregular polysilicon layer 17 is removed. Since the oxide film 15 is exposed in a recessed part of the irregular polysilicon layer 17, it is etched in an etching process of the oxide film 15. Since the polysilicon layer 17 is not etched in an etching process (etching ratio of the polysilicon layer 17 and the oxide film 15 is 2.0:1 or more) of the oxide film 15 in a projecting part of the irregular polysilicon layer 17, the oxide film 15 in a lower part is prevented from being etched and the columnar oxide film pattern 19 is formed. Since a number of columnar storage electrodes are thereby formed, it is possible to increase capacitor capacitance by increasing the surface area of a storage electrode.

Title: Vibrating unit in ink jet recorder
Inventor: MATSUMOTO SHUZO
IPC: B41J2/02
Filed: 1987-06-26
Abstract: PURPOSE:To improve the response of ink-jetting frequency and to reduce interference in the integration, by making a vibrating unit of a triangular plate in a cantilever form. CONSTITUTION:A vibrating unit 30 is so constructed as to have relations of W0>W1 and W1=0, where W0 is a width at a fulcrum 80A of a support body part 80 and W1 is a width at a free end part 30A thereof, namely being made of a triangular plate in a cantilever form. In the vibrating unit 30, the cross sectional area of a part applied with a small-bending moment action is reduced for effectively using a material forming a beam, whereby for the same displacement a required energy is reduced to approximately 2/3 an energy required in a conventional beam having cross sections of uniform size. Therefore, damped vibration is rapidly carried out. Additionally, a mechanical interference is remarkably reduced in the integration because of a small energy of each vibrating unit. Furthermore, the natural frequency of the beam becomes about twice that of a conventional rectangular beam. A degree of freedom for allowing a value of natural vibration to be selected suitably to a high-frequency content of a drive pulse is increased by varying the width of the beam from W0 to W1=0 towards the free end.

Abstract: PURPOSE:To prevent the formation of scratching flaws on the surfaces of steel strips in the stage of coiling the steel strips by forming projecting parts at the edges on both sides of the steel strips thereby increasing resistance forces against loose coiling, tight coiling and lateral slipping during coiling. CONSTITUTION:Before a rolled steel strip 1 is coiled, the strip 1 is pressurized toward the central part in the width direction by vertical pressurizing rollers 3, 3 disposed on both sides during conveying of the strip with rollers 2 of a run-out table, whereby projecting parts 4 of the thickness conforming to the thickness in the central part of the strip 1 are formed in both edge parts. If such steel strip is coiled, the overlapping steel strips overlap with each other in the central part and the parts 4 in both edge parts, whereby the frictional resistance force against lateral slipping is considerably increased, and the formation of surface scratching flaws by the tight coiling, loose coiling or lateral slipping after the coiling is decreased considerably and the steel strip coils having excellent surface quality are obtained.
