IPC: G10H1/34
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To improve the operation efficiency and to lower the cost by relaxing the required precision of key mounting. SOLUTION: At the rear end of a common base end part 5, an elastic piece 6 is provided which has a claw 6a projected behind its lower end.

Title: Azimuth measuring instrument switching system
Inventor: SUZUKI MAKOTO
IPC: G01C19/40
Filed: 1988-03-08
Abstract: PURPOSE:To switch a gyro-system through a simple operation by converting azimuth signals of plural azimuth measuring instruments into signals of an internal form and using the signals of the internal form as control signals for smoothing the operation of an external apparatus. CONSTITUTION:A selecting means 32 is switched from the absolute value azimuth signal betaa of a 2nd gyro-system 2 to the absolute value azimuth signal alphaa of a 1st gyro-system 1 and the signal to a control signal generating means 33 is selected at time ta. As a result, the control signal from the means 33 after the time ta becomes the output gammaa to a signal reproducing means 34 which causes an external apparatus 4 to make smooth tracking operations without step-out. At time tb, the means 32 is switched from the signal alphaa to the signal betaa. Therefore, even if the means 32 is switched from the signal betaa to the signal alphaa at time tc and returned to the previous state (when an input azimuth abruptly changes) at time td, the signal gammaa does not produced any step-out phenomenon, but has a smooth tracking characteristic.

Inventor: OGAWA SHINICHI
IPC: H01J37/32
Filed: 1982-03-31
Abstract: PURPOSE:To improve detection accuracy by detecting contamination and purification degree in the plasma apparatus from a current or voltage value applied to the detecter from discharged plasma. CONSTITUTION:A metal 5 such as platinum covered with an insulator 3 such as quartz and is exposed at the surface 4 within a plasma apparatus is mounted to an internal wall 2 of a dry etching apparatus 1 and a voltage applying circuit 6, a current measuring circuit 7 and an earth 8 are coupled thereto. Immediately after the purification, namely after start of discharging, a film of decomposed product of gas used for dry etching is adhered to the surface of detecter. Therefore, a current does not flow. However, the film is ashed by the oxygen plasma with time and the film becomes thinner. Accordingly a current starts to flow and increases. When the film is perfectly removed, a current saturates. Namely, when a current saturates, purification is completed.

Filed: 1995-03-15
Abstract: PURPOSE: To attain transmission of a signal with high quality without waveform deterioration by connecting a capacitor between a drain or a collector of an output transistor(TR) and either end of a ground pattern arranged in parallel along both sides of a signal line pattern connecting to the output TR. CONSTITUTION: A capacitor 300(301) is connected between a drain or collector of an output TR 50 and at least either end (other end) of a ground pattern 1 arranged in parallel at a prescribed interval along both sides of a signal line pattern 2 connecting to a source or an emitter of the output TR 50. That is, the impedance of the capacitor 300 gets smaller when the frequency increases. Then points a, b are substantially short-circuited at a high frequency band when oscillation is caused by inductors. As a result, the phase and the oscillation amplitude of a signal at the point (a) are completely made equal to those of a signal at the point (b) at the high frequency band and then the oscillation in the signal pattern 2 is made equal to that in the ground pattern 1.

CONSTITUTION:A difference in a radiation rate between an alumina layer and a dark layer used for an insulation cover layer is taken into consideration, and the aforesaid layers are formed with an optimum ratio on a heater surface. For example, a primary coil 1 comprising a rhenium-tungsten wire is helically processed, and a secondary coil 2 and a heater leg section 3 are formed at a position for connecting the two layers. Then, suspension having alumina particles suspended in organic solution is so formed as to have the predetermined thickness as an insulation cover layer 4, using a spray method or the like. In addition, the surface of the layer 4 is coated with suspension composed of a mixture of alumina particles and fine tungsten powder, and sintered in hydrogen atmosphere, thereby forming a dark layer 5. In this case, the dark layer 5 is formed only at an area except for a 40 to 50% range to a ratio of length from the end of the coil 2.

Abstract: PURPOSE:To make the titled device small in size, and also to reduce a magnetic flux leakage in an unnecessary direction by covering the whole moving locus of a laser beam with a band-shaped magnetic pole, using a permanent magnet as a magnetic field generating source, and structuring the device so that a movement of the magnet is parallel to the surface of a recording medium, and a magnetic flux emitted from the permanent magnet is always emitted in the direction of the recording medium. CONSTITUTION:A laser beam is irradiated to a photomagnetic recording medium 1 from an objective lens 3, permanent magnets 5, 6 are fixed to a magnet supporting plate 7, rotated centering around an axis 10, a coil 9 is wound to an iron core 8, and by this electromagnet, a position of the permanent magnets 5, 6 is moved. That is to say, the coil is wound so that a center end 81 of the iron core 8 becomes an N pole, and both side ends 82, 83 become as S pole, when an electric conduction has been executed so that the lower side terminal of the coil 9 becomes a positive voltage. When the lower side of the permanent magnet 5 is the N pole and the lower side of the permanent magnet 6 is the S pole, they are attracted and moved to a position shown in the figure, and stopped. In this state, when positive and negative of a voltage applied to the end of the coil are inverted, the center end 81 of the rotary iron core 8 becomes the S pole, and both the side ends 82, 83 become the N pole, therefore,the position of the permanent magnet moves to the right side and stops.
