IPC: F01L3/08
Filed: 1982-08-21
Abstract: PURPOSE:To prevent the head part of a valve from violently colliding against a valve seat and reduce a seating sound of the valve being a part of the noise of an engine, by tightening a brake sleeve, driven to be moved with a valve stem, in the internal peripheral direction when the valve is closed. CONSTITUTION:If an intake exhaust valve 1 is moved in the direction of closing, a brake sleeve 11 is driven to be moved with a valve stem 1a, and a tapered part 13 is forcibly brought in contact with the seat part 18 of a brake guide 12 immediately before the valve reaches its seat.

Title: Robot controller
Inventor: FUJIMOTO KENJI
IPC: H02P29/00
Filed: 1994-06-03
Abstract: PURPOSE:To enhance the cycle time of a robot by feeding both the rotary angular speed signal of an arm and the torsional angular acceleration signal between the arm and the rotary shaft of a motor back to a current command. CONSTITUTION:The positional difference between the positional signals of a positional command thetar and a motor 14 is multiplied by a positional loop gain 11 to produce a speed command which is delivered to a speed loop. The speed loop serves as a PI controller comprising a speed loop gain 12 and an integrator 13 for determining a current command and constitutes a current loop for feeding a current to the motor 14. The torsional angle thetas between the rotational angles of the motor 14 and the arm is multiplied by a spring constant 15 and transmitted, as an arm driving torque, to the arm in order to determine the rotational angular speed omegaL and rotational angle thetaL of the arm. The rotational angular speed omegaL of the arm is fed back negatively to the current command and the torsional angular acceleration (second order derivative of the torsional angle thetas) is fed back positively.

Title: Fading distortion compensation method and fading distortion compensation system
Inventor: MIURA YASUO
IPC: H04J11/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for compensating fading distortion without being affected even when part of known symbols is remarkably distorted due to other cause than fading fluctuation. SOLUTION: Data are transmitted by inserting known symbols to each sub- carrier in the multi-carrier transmission system. A receiver side is provided with a means 32 that detects distortion of the known symbols, a correction means 33 for the detected distortion, a means 34 that estimates the distortion of information symbols from the detected distortion of the known symbols, and a means 35 that uses the estimated distortion to compensate distortion of received data. The correction means 33 calculates a correction value for the detected distortion of the known symbols that are distorted remarkably based on a gradient of mean values of the distortion of the known symbols for each sub carrier and on the detected distortion of the known symbols of other sub carrier that are received at the same time.

Title: Yarn winding method and device thereof
Inventor: OHASHI KENJI
IPC: B65H54/28
Filed: 1988-06-14
Abstract: PURPOSE:To increase an intersection of yarn as well as to keep off any trouble such as sloughing or the like at the time of high-speed opening by changing the wind number of a package in one traverse of the yarn. CONSTITUTION:Yarn is wound up with a drum provided with a traverse groove of two left-handed winds and three right-handed winds. At this time, the yarn is wound up as traversing along an arrow, and at the time of left going (an arrow 6 direction), a package number is one wind, but at the time of right going (an arrow 7 direction), it comes to 1.5 wind. In brief, supposing that a traverse is started from a point A, the yarn is wound up along 1' 14 loci, and points C2, C3, C5, C6 where full lines themselves are crossed and point C1, C4, C7, C8 where broken lines themselves are crossed at this time come to an intersection with the actual yarn, and the intersection is produced in order of C1, C2, C3...C8. Thus, the intersection is increased in quantity, so that a package outer surface is hard to be disarranged and, what is more, sloughing and yarn tangling are hard to occur as well at the time of high-speed opening.

Filed: 1988-06-14
Abstract: PURPOSE:To reduce refrigerant sound without increasing the resistance of discharging gas not more than required by providing a heat exchanger at the refrigerant input side of an auxiliary pressure reducing unit provided with a bypass passage for introducing part of high pressure refrigerant from a high pressure side to a low pressure side. CONSTITUTION:A bypass passage 9 for introducing part of high pressure refrigerant is connected between the discharge tube 2 and the suction tube 7 of a refrigerant compressor 1, and a motor-driven expansion valve to become an auxiliary pressure reducing unit 10 and a heat exchanger 12 with a heat sink fin 11 at the refrigerant input side of the unit 10 are disposed in the passage 9. For example, when a room is not so necessary to be cooled, if the rotating speed of a fan is extremely reduced, the blowing air amount to a condenser 3 is unavoidably reduced, its temperature becomes high, and the refrigerant pressure increases. However, since the exchanger 12 and the unit 10 are disposed in the passage 9, the valve of the unit 10 is opened, and the rise of the high pressure of a refrigerant circuit is suppressed by the short-circuit of part of the refrigerant to an air/liquid separator 8 through the exchanger 12 and the unit 10 to be partly heat dissipated.

Title: Superconductive conductor
Inventor: HAMASHIMA KOTARO
IPC: H01B12/12
Filed: 1991-06-19
Abstract: PURPOSE:To prevent quenching by forming a superconductive coil by winding many superconductive wires on the outside circumference of a circular or elliptic hollow pipe and by inhibiting frictional heating between the superconductive wires and the pipe, and between the superconductive wires. CONSTITUTION:A superconductive conductor 3 is formed by winding superconductive wires 2, in moderate numbers, formed by twisting many superconductive strands on the outside circumference of a hollow pipe 1. The pipe 1 is formed in circular or elliptic shape by using stainless steel. an aluminium alloy, a copper alloy, ceramics etc. Therefore, the conductive wires 2 are pressed to the surface of the pipe 1 and will not float from the surface, and has no acute end portion. Thus, no gap is generated between tire conductive wires 2. This prevents quenching without generating heating caused by sliding the conductive wires 2 over the surface of the pipe even if the conductor 3 is excited, or without generating frictional heating between the conductive wires 2.

Title: Gas supply of two-fluid nozzle
Inventor: KAJI RIYUUICHI
IPC: B05B7/06
Filed: 1978-11-29
Abstract: PURPOSE: To reduce the running cost of an apparatus and to carry out effectively the atomization of absorbed liquid in th apparatus for treating high temperature gas by atomizing the liquid with vapor of a liquid having lower boiling point than the temperature of the gas.  
     CONSTITUTION: The structure of nozzle used is the same as that of conventional two-fluid nozzle. A pipe 3 through which absorbed liquid 5 is transferred to a nozzle 3, is a double-pipe. The internal pipe 2 is used for transporting the absorbed liquid. Cooling water flows through the external pipe 1, thereby the boiling of the absorbed liquid within the pipe and the nozzle 3 is prevented. As the cooling water flowing through the external pipe 1 approaches the nozzle 3 within an absorption tower 4, the temperature rises, because the cooling water is contacted with high temperature gas. The cooling water boils, evaporates and turns into gas. As a result, volume is greatly increased, velocity at the tip of the nozzle is increased and the adsorbed liquid is atomized at the jetting port.

Abstract: A watch contains a date indicator ring and a day of week indicator ring. A switching wheel is displaceable selectively into meshing engagement with the indicator rings to effect adjustment thereof. The switching wheel is actuated by a shaft which is axially displaceable between selection and working positions. In its selection position, the shaft can be rotated in either direction to selectively place the switching wheel in one of two preliminary locations corresponding to a date ring adjustment location and a day of week ring adjustment position. By then axially displacing the shaft to its working position, the switching wheel is displaced to a final location to effect the previously selected mode of adjustment. Such adjustment is effected by rotating the shaft in either direction to rotate the respective indicator ring in either direction.
