Filed: 1993-02-09
Abstract: PURPOSE:To easily measure radon which has an extremely low concentration and is dissolved in water by dipping a measuring device with carbon deposition film into water to be measured and then detecting the track of alpha particle generated by radon. CONSTITUTION:Carbon electrodes 2, 2 are provided inside a vacuum chamber 1, a plastic film 3 which is for example 20X20X1mm is laid out below it, and spark discharge is made for 90 seconds under a degree of vacuum of 5X10<-4>Pa and a spark current of 35A, thus forming a carbon deposition film 4 which is 10-15mum thick on the film 3. The carbon deposition film 5 is not peeled, is stable against an organic solvent, and does not react with radon in air. For measuring the radon in water, the film 5 is set to a holder 6 made of teflon and is suspended by a drilling hole, etc., by a wire 7. After the film 5 is dipped into the water to be measured for a certain amount of time, it is etched by 6 N NaOH, the number of alpha particles is counted by a microscope, and then radon concentration within water is measured, thus estimating the state of underground water and crack of rock ground.

Title: Semiconductor device
Inventor: MATSUDA HIDEO
IPC: H01L29/74
Filed: 1985-03-07
Abstract: PURPOSE:To obtain the thyristor of a low on-state voltage by sufficiently thickening a thickness of a P-type layer of the lowest impurity concentration compared with other P-type layers and N-type layers in the thyristor and using GaAs as a principal material so as to increase a dependable temperature over 150 deg.C. CONSTITUTION:As a thermal excitation current of GaAs is exceedingly small compared with that of Si and also a value of off-state current is low, if it is assumed that the permissible off-state currents are the same, the thyristor of GaAs is capable of operating at higher temperature. However, if GaAs is used as a principal material while keeping a conventional structure, the sufficient on-state characteristics can not be obtained as an on-state voltage is high. When a thickness of a PB layer 3 is large sufficiently compared with other layers and the impurity concentration is made lowest, a reverse voltage is blocked by the junction J3 of an NE layer 4 and the PB layer 3 and an off-state voltage forward direction is blocked by the junction J2 of the PB layer 3 and an NB layer 2. A gate electrode 7 is arranged on the NB layer 2 and a forward voltage which makes an anode 5 positive is applied to a cathode 6. Then a negative bias voltage which makes the gate electrode 7 negative is applied to the anode 5, thereby enabling turn-on.

Title: Accumulator device for automatic transmission
Inventor: KAWANO TORU
IPC: F16H61/10
Filed: 1990-02-22
Abstract: PURPOSE:To smooth a build-up of clamping pressure by making it function with a smaller spring constant than that of each of first and second springs when a movable washer separates from a stopper part through movement of an accumulator piston via the second spring. CONSTITUTION:When working pressure, selecting the operaing states of a friction element, exceeds the spring force of a second spring 56, an accumulator piston 52 moves in a cylinder 51 in the A1 direction. In this case, as a first spring 55 is contracted by dint of preload, the spring force is larger than the second one. When deformation in the second spring 56 glows larger and a movable washer 53 separates from a stopper part 54, combined spring force of these first and second springs 55, 56 works there, but this spring constant is smaller than that of these two springs 55, 56, and a degree of absorption for clamping pressure becomes larger. Thus a buildup of the clamping pressure at the initial stage of clamping the friction element is smoothable.

Title: Check valve
Inventor: SATO TOSHIHARU
IPC: F02M21/02
Filed: 1995-03-03
Abstract: PURPOSE: To reduce a valve from chattering and improve durability by laying a magnet near a position where a valve compresses a spring and travels at the time of opening, so as to attract and fix the valve with the magnetic force thereof, and setting the attraction force slightly lower than the compression reaction of the spring. CONSTITUTION: A magnet 73 is fixed to the end of a spring bearing 70 at a section coming in contact with a valve 65 at the time of valve opening operation, and an attraction surface 65a is formed on the back of the valve 65 at a position faced to the magnet 73. Also, the valve 65 is made of a magnetic substance, or a magnetic material is buried in the surface 65. The valve 65 is attracted and fixed with magnetism at the time of valve opening operation and the valve 65 is kept in an open state against the compression reaction of a spring 72. In this case, the attraction force of the magnet 73 is set slightly lower than the compression reaction of the spring 72, so as to allow the valve 65 to part from the magnet 73 for closure at uniform vertical flow pressure.  As a result, when a high pressure fluid flows across the valve 65, the vibration thereof like the repetition of open/close operations can be restrained, and the collision thereof with an O-ring 64 is lessened, thereby improving durability.

Abstract: PURPOSE:To maintain the thickness of an applied resist film constant by a method wherein a mechanism for control of a pressure in a resist coating atmosphere and the pressure in the resist coating atmosphere is controlled. CONSTITUTION:A pressure in a coating chamber 4, i.e., a pressure in a resist coating atmosphere, is detected by a pressure sensor 8 provided in the coating chamber 4. A pressure controller 9 controls the revolutions of a suction fan 6a and an exhaust fan 6b in accordance with the detected value given by the pressure sensor 8 to maintain the pressure in the resist coating atmosphere at a predetermined value. That is, if the pressure in the resist coating atmosphere is higher than the predetermined value, the revolution of the suction fan 6a is reduced and the revolution of the exhaust fan 6b is increased and, to the contrary, if the pressure in the resist coating atmosphere is lower than the predetermined value, the revolution of the suction fan 6a is increased and the revolution of the exhaust fan is decreased to avoid the fluctuation of the pressure in the resist coating atmosphere. With this constitution, the thickness of the coated resist film can be more uniform.
