IPC: G05D3/12
Filed: 1985-09-06
Abstract: PURPOSE:To obtain a small-sized, lightweight, and inexpensive position controller by constituting the controller including a control circuit which varies the output of an oscillator according to a position signal and selects one of a couple of ultrasonic vibrators to control the level and direction of an ultrasonic traveling wave. CONSTITUTION:A position detecting circuit 7 inputs the output of the 2nd oscillator 4 and the output of a detector 6 and measures the delay time between both signals to detect the position of a slider 3, outputting the position signal 7. The signal 71 is inputted to a control circuit 8 to perform processing such as the generation of a speed signal when necessary, and the signal is compared with a target position or target speed specified with a control input signal 80 supplied from external control equipment. The output level of the 1st oscillator 82 determining the output levels of the 1st ultrasonic vibrators 2 and 2' is set on the bases of the comparison level and the circuit is switched to determine which of the vibrators 2 and 2; is used as an oscillator and which of them is used as a vibration absorber. Consequently, the magnitude and direction of driving ultrasonic vibrations generated on the rail 1 are determined.

Title: Amplifying device of traveling wave tube
Inventor: HIROI MAMORU
IPC: H03F3/58
Filed: 1982-11-12
Abstract: PURPOSE:To obtain amplifying characteristics of high quality with a device of a small output by extracting the distortion signal of a slow wave circuit from the half way of the slow wave circuit and using said distortion signal to control a pre-distortion circuit and to offset the distortions. CONSTITUTION:The input signal passed through a pre-distortion circuit 9 is amplified by a slow wave circuit 2 in a traveling wave tube 1 and delivered through an output window. In this case, the amplified signal is extracted from the attenuator side of the input side helix. Thus the distortion proportional to the input signal can be extracted. Making use of this extracted distortion signal, a control circuit 10 controls the circuit 9. Thus it is possible to apply the distortion opposite to the distortion of the tube 1. As a result, the compensation of distortion makes it possible to obtain an amplifying circuit of the tube 1 with a low distortion factor without effected by the characteristics of the tube 1.

Title: Scanning tunneling microscope
Inventor: MIYAMOTO YASUSHI
IPC: H01J37/252
Filed: 1990-07-26
Abstract: PURPOSE:To accurately detect tunnel current flowing between a probe and a specimen by maintaining a guard ring electrode and a probe electrode at an equal potential and eliminating flow-in of current to the probe electrode. CONSTITUTION:A bias voltage signal S1 is input to a non-inverted input of an operational amplifier 28, while an inverted input is connected to a probe electrode 14 so that tunnel current flowing between a probe 12 and a specimen 10 is converted into a voltage signal while the electrode 14 is maintained at a potential equal to that of a bias input voltage. An operational amplifier 30 subtracts the bias voltage from a bias addition tunnel current signal S2 which is output from the amplifier 28 and outputs a tunnel current signal S3 by a differential amplifier. When voltage for scanning is applied to a driving electrode 18, current from the electrode 18 via capacitance components of insulating members 22, 24 to the electrode 14 flows into a guard ring electrode 20 but does not flow into the electrode 14. Therefore, only tunnel current flowing between the probe 12 and the specimen 10 is detected.

Title: Switchboard with bursting device
Inventor: IKENO YOSHIHIRO
IPC: H02B1/28
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent the side plates of neighboring switchboards from being deformed even if an internal pressure rises, by bending outward substantially in U shape the both ends of the side plates of a switchboard so as to make them contacted each neighboring board. SOLUTION: The outside circumference of the box of a switchboard is made up of a door unit 12 fastened with a hinge 71, a back side plate 15, a bottom plate 14, a top plate and two side plates 1 having fabricated ends 1t. The ends 1t, bent and formed in a U shape, prevents a neighboring switchboard from coming closer to the switchboard exceeding a dotted line S shown in Figure when a plurality of switchboards are placed in a row with the ends 1t contacting each other. If a failure occurs in relation to the occurrence of an arc inside a box this condition, pressure rises inside the board. When it exceeds preset operating pressure of an internal bursting device, the bursting device is operated and the pressure rise inside the switchboard deforms the side plates 1 up to dotted line 1h as shown in Figure.  However, the deformation does not reach the line S, thereby avoiding the deformation on side plates of the neighboring boards.

Abstract: PURPOSE:To enable to control an excess air ratio almost at a fixed level by adjusting a quantity of combustion, by arranging a variable dynamic pressure damper adjusting a secondary air passage resistance automatically by moving in a tilting state through a flow speed of secondary air, that is, its dynamic pressure within a secondary air passage. CONSTITUTION:As blast pressure becomes high relatively when correction control of a primary excess air ratio PA% is made so that it becomes constant, the lower a combustion region becomes, the larger an excess air ratio (m) becomes suddenly further. When a variable dynamic pressure damper 15, therefore, and a stationary secondary air throttle plate 16 are arranged in the vicinity of a secondary air passage 7, the variable dynamic pressure damper 15 is tilted greatly through dynamic pressure of a secondary air flow when a quantity of combustion is large and an inclination becomes small according as the quantity of combustion becomes small. In other wards, it becomes that a cross-sectional area of the secondary air passage can be varied from a big area to a small area, that is, a secondary air passage resistance can be varied from small resistance to a large resistance automatically. Then the excess air ratio (m) can be controlled almost at a fixed level even if the quantity of combustion is adjusted.
