Filed: 1991-03-06
Abstract: PURPOSE:To improve integrity of equipment and to confirm safety of a nuclear reactor by confirming braking function from occurrence of voltage and amperage spike at cutting-off of an electric power source of an electromagnetic brake, and armature releasing time. CONSTITUTION:In an electromagnetic brake 28, when a coil 31 is not connected electrically, a plurality of springs 40 push an armature 33 upwardly and a turning axis 14 of an electrical motor is constrained. By detecting a spike generated to voltage and amperage when an electrical power source thereof is cut off (OFF), and by measuring armature releasing time, integrity of the brake spring force can be confirmed. Then, using an oscilloscope connected to the brake 28, existence of the spike is confirmed and the armature releasing time is measured. In this way, only by cutting off (OFF) the power source and by observing wave form of the voltage and amperage at that timing, the braking function can be confirmed and safety of a nuclear reactor can be assured as well as integrity of equipment can be improved.

Title: Radar for vehicle
Inventor: KUBOTA YUICHI
IPC: G01S17/93
Filed: 1993-03-01
Abstract: PURPOSE:To obtain a radar for vehicle using pulse laser light in which an accurate distance measurement data can be attained even when the reflected pulse has a level higher than saturation level. CONSTITUTION:Pulse laser light radiated from an LD 10 and reflected on an object is received at a light receiving section 16 and shaped through a comparator 20 into a rectangular pulse which is fed to an RS-FF 14. The RS-FF 14 produces a distance signal corresponding to the time interval between a light emission signal received from a monostable multivibrator 12 and a light receiving signal received from the comparator 20 and the distance signal is fed to a distance operating circuit 22. The distance operating circuit 22 operates the distance upto an object based on the distance signal and delivers the distance thus operated to a microcomputor 24. The microcomputor 24 corrects the distance measurement data based on an integrated voltage value of rectangular pulse received through an integrating circuit 26, a peak hold circuit 28, and an A/D converter 30. This constitution allows correction of light receiving level exceeding a saturation level based on an integrated voltage value.

Title: Deflection yoke device
Inventor: TAGAMI ETSUJI
IPC: H04N3/23
Filed: 1989-02-20
Abstract: PURPOSE:To suppress positive trilemma in a picture area when used in combination with a frame aberration correcting coil by connecting in parallel a pair of raster distortion correcting coils with each of which a single diode is connected in series in such a manner that their respective diodes are facing in opposite directions. CONSTITUTION:A vertical deflection current flows through an upper coil 6 only when a specific voltage + V0 or over is retained. Thus, when this voltage level is not retained, no pin-cushion type magnetic field is generated by the coil 6, causing only the barrel distortion of diametrical magnetic field to be weakened with the resulting reduced positive trilemma (intersection of R and B beams) in the upper half of a picture area 1. Also, a vertical deflection current flows through a lower coil 8 only when a diode connected in opposite direction stays ON i.e., -V0 or less is retained, causing positive trilemma to be reduced in the lower half of the area I. With voltage level being +V0 or over, an element 5 is activated and a pin-cushion magnetic field is produced, making it possible to correct pin-cushion distortion in the upper portion of the raster and negative trilemma in an upper picture area II. With voltage level being -V0 or less, an element 7 is activated for correction in a similar manner. The continuity time for the coils 6, 7 is established through selecting of characteristics of the elements 6, 7, series count, and value of a resistance 9.

Title: Method for constant speed taking-up of thread for feeding thread to double twister
Inventor: TSUJIMOTO KIMIO
IPC: B65H51/30
Filed: 1986-02-26
Abstract: PURPOSE:To make smooth thread take-up from a cocoon possible without end breakage by reducing the number of revolutions of a spindle for rotating an inclined bobbin in proportion to decrease in a measured distance between a thread take-up position on a package surface and a sensor. CONSTITUTION:In taking-up a thread Y on an inclined bobbin 2 having an inclination of 0.5-5.0, the number of revolutions of a spindle 23 is reduced in proportion to decrease in a measured distance M between a thread take-up position on the surface of a package 1, which is changed by the movement of a traverse guide 15, and an optical sensor 18 fixed to a traverse guide rail 17 to always take up the thread at a constant taking-up speed. In addition to that, a constant speed rotating feed roller 14 feeds the thread at constant speed to the inclined bobbin 2, and presses a roller bell 16 on the surface of a yarn layer applying a fixed constant pressure to raise take-up hardness as high as possible. Consequently, a thread feeding package for a double twister which has large take-up capacity, a small lease angle, and the very excellent-property of thread take-up from a cocoon can be produced.

IPC: C23C14/24
Filed: 1986-02-26
Abstract: PURPOSE:To prevent fine powder or fregments from being exposed to introduced gas, by providing a means storing a solid so as to attach the same to an introduced gas passage. CONSTITUTION:A part of the vapor deposition substance generated by the thermal cracking of stock gas in a thermal cracking part 1 is diffused to be cooled to the low temp. of a conduit 8 and fixed to the pipe wall of said conduit or converted to a fine powder. A solid storing means 10 is attached to the conduit 8 in order to store thus formed fine powder and the solid fixed to the pipe wall and subsequently released. By this means 10, a valve is prevented from generating seal inferior by the solid of the vapor deposition substance. Because the deposited substance is not exposed to the flow of gas, the quality of a vapor deposition membrane receives no adverse effect and the flow of the stock gas is also not obstructed. Therefore, the reliability of the valve adjacent to a gas source cell can be enhanced.
