Title: Abrasion method and abrasion device used in it
Inventor: MIYAJIMA MOTOMORI
IPC: B24B37/30
Filed: 1990-07-03
Abstract: PURPOSE:To enable only a thin film to be abraded with improved controllability by allowing an object to be abraded using an abrasion liquid which contains an alkali chemical liquid or an acid chemical liquid with a first hydrogen ion index (pH value) and at the same time obtaining a second pH value by measuring the pH value of an abrasion liquid after being used for abrasion. CONSTITUTION:An abrasion liquid which includes an alkali chemical liquid or an acid liquid with a first hydrogen ion index (pH value) is used as an abrasion liquid. Thus, a hydroxide group (OH-) or a hydrogenion (H-) within an abrasion liquid which contributes to chemical reaction with an object to be abraded are consumed after abrasion is started. Therefore, the pH value varies depending on whether the object to be abraded exists or not. In this case, when the pH value of the abrasion liquid after it is used for abrasion returns to the pH value of initial abrasion liquid, it is judged that abrasion of the object to be abraded ended and abrasion stops at this point, thus enabling only the thin film to be abraded with improved controllability regardless of presence or absence of fluctuation of abrasion rate.

Abstract: PURPOSE:To improve the working efficiency in a railroad working by allowing a railroad working vehicle to travel as it is on a rail by installing each wheel for the traveling on the rail which has the less diameter than the diameter of the traveling tire, inside the tires for front and rear wheels. CONSTITUTION:In the application of a working vehicle such as power shovel equipped with four-wheel drive type traveling tires 2 and 3 in the front and rear parts, wheels 4 and 5 for the traveling on a rail which has the slightly less diameter than the diameter of the tires 2 and 3 are installed inside the tires 2 and 3. The wheels are installed by using an insulating member 6 and an insulating bolt 7, and safety is secured. The step difference H between the tires 2 and 3 and wheels 4 and 5 is set so that the tires 2 and 3 do not contact a signal wire laid along a rail 9 and railroad ties, when the power shovel is traveled on the rail. In the traveling on the rail, the working vehicle is traveled by itself by driving a build-in power unit.

Title: Semiconductor integrated circuit
Inventor: YOSHIMOTO MASAHIKO
IPC: H01L27/04
Filed: 1980-12-11
Abstract: PURPOSE:To prevent the variation of substrate bias generating voltage even when line voltage varies by mounting a clamping circuit at the output side of a substrate potential generating circuit and clamping the upper and lower limits or one side of the oscillating output of a drive circuit. CONSTITUTION:Rectangular waves are oscillated 201 at predetermined frequency, and supplied to the drive circuit 202. When the threshold voltage of the FET201 of the voltage clamping circuit 210 is Vth, the upper limit of the output of the drive circuit 202 is clamped to VR+Vth, and fed to a coupling capacity 203. The potential of a node 207 is changed into the rectangular waves, which have  the +Vth maximum value and the minimum value of Vth-(VR+Vth)=-VR, by the clamping action of an FET205, electrons are scooped out to a substrate 208 through an FET204 by the negative voltage, and the substrate voltage VR under a stationary state shifts only by the threshold value Vth of the FET and reaches approximately Vth-VR. Accordingly, when VR is set to value suffuiciently lower than a variation section of the line voltage Vcc, the substrate bias generating voltage is fixed to (Vth-VR) without regard to the variation of Vcc.

Inventor: NAKAMURA NATSUKI
IPC: H03M1/00
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To reduce the number of quantized bits by changing a quantization step size in response to a level of an input analog signal, adding a code resulting from the step size to quantized data, allowing the D/A conversion stage to detect the code and applying inverting quantization to the quantized data depending on the size thereby utilizing the quantized bit number effectively. SOLUTION: An input signal is given to an A/D converter circuit (variable step size converter) 2 and also to an A/D converter circuit (fixed step size converter) 3, where an input signal level is detected. A step size information generator in which an optimum step size with respect to each input signal level is set provides an output of a step size based on the detected level to the A/D converter circuit 2. The step size of the A/D converter circuit 2 that receives the output of the step size information is changed so that the A/D converter 2 provides a digital output whose level is as high as possible within a prescribed range. The step size from the circuit 4, is coded by a coder 5 and multiplexed on quantized data at a time division multiplexer 6.

Title: Satellite communication system
Inventor: TSUJI AKIRA
IPC: H04B7/155
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To prevent the service grade of an entire system from being lowered when the number of line setting requests from a certain user is increased and to prevent system satellite resources from being already exhausted in a group when allocating a satellite frequency only from the system satellite resources allocated for user. SOLUTION: An average call amount calculating part 12 by users calculates an average call amount by statistical processing. When the reported average call amount gets adverse rather than a service grade value defined for a relevant user, a user unit satellite resource redefinition processing part 13 dispenses frequency resources required for securing the service grade value from a system reserve area shared by systems to this user. When it is judged that the average call amount can keep the service grade value even without using any resource in the system reserve area, the satellite frequency resources dispensed for this user are returned to the system reserve area as a free area.

Title: Intake device for rotary piston engine with supercharger
Inventor: OKIMOTO HARUO
IPC: F02B53/06
Filed: 1980-12-15
Abstract: PURPOSE: To enable smooth operation, by providing a main and an accessory intake ports, connecting only the accessory intake port to an exhaust port and connecting the main and the accessory intake ports to the downstream side of a supercharger and by opening the accessory intake port when the intake pressure downstream to the supercharger has risen abnormally.  
     CONSTITUTION: In operation under ow load, the degree of opening of a throttle valve 24 is low and a diaphragm 19 is displaced in a direction A 1  to close a valve 17 through a connecting member 23 and a lever 23a. As a result, the negative intake pressure does not sucks exhaust gas through an accessory intake port 16, so that thin gas is kept from flowing into an intake chamber 25. When the throttle valve 24 is fully open and supercharged intake is efected, the pressure of a chamber 18b goes up due to the rise in the pressure of an intake passage 14 to displace the diaphragm 19 in a direction B 1  to open the valve 17. As a result, the intake chamber 25 is connected to the intake passage 14 to heighten the pressure of the chamber 25 to keep the exhaust gas from flowing into the chamber. According to this constitution, abnormal combustion is avoided to smooth the operation.

IPC: E04B1/00
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To maintain a balcony horizontally by forming a joining surface of a joining member in a slope surface projected from the outside of a building skeleton. SOLUTION: The vertical surface 27 of a balcony unit 20 is adapted to come in contact with the joining surface 31 of a joining member 30 which is arranged to form a slope surface. During this joining work, a triangle-shaped guide hole 28 is fittingly inserted into a guide pin 32, thereby supporting the bottom 25A with a receiving surface section 33. Since the tip of the unit separated from a building skeleton 14 is turned upward, the unit 20 is arranged to come in contact with the joining member 30. In a state joined with the joining member 30, the tip of the unit drops by self weight so that it may be maintained horizontally. Since the guide hole 28 is a triangle in shape, it may be possible to enlarge an opening area, thereby facilitating fit-in insertion and execute joining work swiftly by supporting an unstable unit 20 with the receiving surface area 33.
