Title: Manufacture of semiconductor substrate
Inventor: WATANABE YOSHIO
IPC: H01L21/768
Filed: 1990-02-20
Abstract: PURPOSE:Not only to flatten the irregularities formed on the surface of a semiconductor substrate but also to make all the surface of it uniformly smooth through a simple manufacturing process by a method wherein a resin layer is formed on the semiconductor substrate, which is pre-burned to be semi-hardened, and a squeegee to which a prescribed pressure is applied is made to sweep over the burned resin layer. CONSTITUTION:A method, where a resin layer is formed on a semiconductor substrate 102 to flatten the irregularities and the waves formed on the surface of the substrate 102, is composed of a first process in which a resin layer 104 is formed on the semiconductor substrate 102, a second process in which the resin layer 104 is pre-burned to be semi-hardened, and a third process in which a squeegee to which a prescribed pressure is applied is made to run over the burned resin layer 104 coming in close contact with it to flatten the surface of the resin layer 104. For instance, a polyimide 104 is applied as uniformly as possible onto the semiconductor substrate 102 provided with steps 4mum in height through a spin coater. Then, the substrate 102 is burned at a temperature of 100-130 deg.C for 15 minutes or so so as to prevent the polyimide 104 from being fully hardened. In succession, a squeegee to which a prescribed pressure is applied is made to sweep over the polyimide layer 104 in contact with it.

Abstract: PURPOSE:To improve the talking efficiency by using a control channel for talking when no idle channel exists in the talking channel and shifting the talking to the idle talking channel when an idle talking channel takes place in the use of the control channel. CONSTITUTION:When two channels CH1, CH2 are available in plural mobile stations 11, 12, for example, when a control channel is set to the CH1 and the talking channel is set to the CH2. When the talking channel CH2 is in use, that is, no idle talking channel CH2 exists, the control channel CH1 is used as the talking channel and when the control channel CH1 is used for talking and the talking channel CH2 is idle, the talking of the control channel CH1 is shifted to the talking channel CH2. Thus, a few channels are effectively used and the talking efficiency is improved.

Title: Semiconductor switch break control system
Inventor: YOSHINO TETSUO
IPC: H03K17/13
Filed: 1979-03-30
Abstract: PURPOSE:To make it possible to simplify circuit constitution while lessening the generation of inverse electromotive force due to inductive load control, by stopping gate drive when a signal current is inverted in polarity or at zero level. CONSTITUTION:In the circuit consisting of signal source 1, inductive load 2, semiconductor switch circuit 3, gate driving circuit 4, gate drive control circuit 5, etc., the application of an OFF control signal to control terminal CNT stops the gate drive of one SCR where no gate signal flows and also holds the other SCR in an On state by supplying the gate current in succession, so that even if a passing signal (load) current would decrease below a holding current value, the operation will be controlled to prevent on OFF state from being set immediately. Since a reverse stop state is set when the passing current value further decreases and the current direction is inverted, the other SCR is placed in the OFF state and no gate current is supplied to SCR, so that circuit 3 will be in the OFF state on the whole.

Title: Gasket
Inventor: TSUCHIMOTO YASUSHI
IPC: B29B15/00
Filed: 1981-03-19
Abstract: PURPOSE: To provide a gasket that takes full advantage of the characteristics of a fiber material and a rubber material and has an excellent function of preventing water leakage from a contact surface even under a small clamping pressure, by kneading a raw material comprising the fiber material and rubber material with a water-swellable material and then vulcanizing and forming the compound into a sheet form.  
     CONSTITUTION: A raw material for gasket comprising 50W90wt.% fiber material and 10W50wt.% rubber material is blended with 1W30wt.% water-insoluble, water-swellable material, based on the weight of the above-mentioned raw material. The resulting mixture is kneaded and then vulcanized and formed into a sheet. When the amount of the fiber material in the raw material is less than 50%, the tensile strength and heat resistance of the gasket are lowered. When it exceeds 90%, the sealing properties of the gasket are lowered. Therefore it is preferable to select the mixing ratio of the fiber material and rubber material within the above-mentioned range. The water-swellable material to be used is a hydrophilic and water-insoluble polymeric substance containing a nonionic hydrophilic group, e.g., a copolymer of acrylic acid or its salt with divinylbenzene.

Abstract: PURPOSE:To ensure the reduction of vibration transmitted from rear wheels to a car body and provide a better ride by holding the damping coefficient of a variable damping force shock absorber at the rear wheel side under the low condition until the rear wheel vibrates after the front wheel vibrates. CONSTITUTION:Vibration detectors 17, 18 provided on the front and rear portions of a car body to detect vibration transmitted from front and rear wheels 11, 12 supply the output signals to the input of a control circuit 16. When for example the front wheel 11 rides on a projection or the like and signals are sent from a front wheel vibration detector 17 to the input of the control circuit, a variable damping force mechanism 15 attached to a variable damping force rear wheel shock absorber 14 is controlled to reduce the damping coefficient of the rear wheel shock absorber 14. And then, when the rear wheel 12 rides on the same projection to generate signals from the rear wheel vibration detector 18, the damping coefficient of the rear wheel shock absorber 14 is returned to the original value after a predetermined time.

Abstract: PURPOSE:To enhance the durability of a ship propeller elevating device and as well to prevent the same from generating noise, by relieving an excessive amount of return liquid for a pump to a reservoir through a check valve and a piston device bypassing a down relief valve. CONSTITUTION:A reversible hydraulic pump 9 feeds liquid under pressure into a pipe llne 10 through a pipe line 11. When an outboard engine is lowered by means of a tilt cylinder, a hydraulic pressure induced by a liquid having an amount which is excess of an appropriate amount of liquid flowing through the pipe line 10 upon down operation of the engine moves a piston 21a in a hydraulic pressure regulating means 21 leftward to relieve the excessive amount of liquid in the pipe line 11. Accordingly, an appropriate amount of pressure liquid necessary for down operation of the engine is fed to the upper hydraulic chamber 6d of a tilt cylinder 6 through a check valve 12 and a pipe line 14, and the lower hydraulic chamber 6c of the tilt cylinder 6 and the hydraulic cylinder 7a of a trim cylinder 7 may be discharged into the pipe line 11 through a pipe line 13 and the check valve 12. Since upon normal operation the engine elevating device operates at a low pressure, the durability of the device may be enhanced and as well noise generation may be prevented.
