Title: Oscillating circuit
Inventor: KATO HIROJI
IPC: H03K4/54
Filed: 1984-12-18
Abstract: PURPOSE:To obtain an oscillation output whose delay time is remarkably less by a small sized and inexpensive start resistance by inserting a parallel circuit comprising a rectifier element and a capacitor in series with a positive feedback circuit comprising a feedback winding, a base resistor and a switching element. CONSTITUTION:A start current flows from a power supply 18 through a start resistor 11, a starting capacitor 16, a base resistor 15 and a feedback winding 14 and as the starting capacitor 16 is charged, a transistor (TR) 12 is conductive. The TR12 repeats two states of saturation and interruption to continue the oscillation. The capacitance of the starting capacitor 16 can be a capacitance having only to give positive feedback when the TR12 is conducted and a collector current flows. The starting current flowing through the starting resistor 11 can be a minimum current by which the TR12 is brought into the positive feedback state.

Title: Optical switch and production thereof
Inventor: IWANO HIDEAKI
IPC: G02F1/025
Filed: 1989-10-12
Abstract: PURPOSE:To obtain the Mach-Zehnder type optical switch which allows the high-speed switching of a high extinction ratio by optical waveguides of a low loss and can be easily produced by constituting a semiconductor substrate of a III-V compd. semiconductor and the optical waveguides of a II-VI compd. semiconductor. CONSTITUTION:The optical waveguides 102, 103 consisting of ZnSSe are disposed on the single crystal substrate 101 consisting of n type GaAs. The incident light 104 from one side onto the optical waveguide is divided to two light waves by the Y-branch waveguide. An electrode 105 is provided on the one waveguide and a primary electrooptic effect is generated by impressing a voltage thereto, by which modulation can be applied to the phase constant. The switching to turn exit light 106 on and off is, therefore, possible if a suitable phase difference is provided to the two light waves at the time when these light waves join in another Y branch waveguide. The switch of the high extinction ratio which lessens the propagation loss of light and can lower the noise level as compared with signal light is obtd. in this way.

Title: Oscillation type actuator
Inventor: KURIYAMA YOSHIHIKO
IPC: G11B21/02
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To permit a highly accurate and high speed positioning by setting a coil part so as to have one coil main body and so as to generate torque in the coil main body and so that a torque arm length is roughly in the circumferential direction of the oscillation of an arm part to make a generated torque larger. SOLUTION: A counter force and a vibration load are suppressed by canceling a coil thrust becoming the cause of the vibration to be transmitted to a supporting shaft 20 being the center of rotation by forming the coil main body while winding the wire of a coil part 30 around the surroundings of an axis 36 along the longitudinal direction of an arm part 26 and by setting the torque arm length to be roughly in the circumferential direction of the oscillation of the arm part 26. As a result, the resonance frequency of an oscillation type actuator 24 can be made higher and the frequency band of the control current of a coil can be broadened. The whole of permanent magnetic units 32 is made to be in a circular-arc shape along the oscillating direction of the arm part 26 by forming the coil part 30 in a wide width in the longitudinal direction of the arm part 26. Moreover, a magnetic distribution is adjusted by forming a bend at the center of the coil main body 34.

Title: Underwater shield tunnel method and shield machine to be used therefor
Inventor: TANAKA KOICHI
IPC: E21D9/06
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a segment by a method wherein excavation is conducted while the slurry pressure of a starting shaft is made to be a specified value, a shield machine is removed, a pipe body is inserted from the shaft and a peripheral wall is lined. SOLUTION: A cutter head 2 for the shield machine 1 is faced to the starting entrance S1 of a starting shaft S, and the slurry pressure P1 of the shaft S is set at a value larger than the sum total of face earth pressure and groundwater pressure. Driving force DF by the difference ΔP of slurry pressure P1 and total pressure works to a bulkhead 4 for the shield machine 1 and a shield tunnel T is excavated, and difference pressure ΔP works to a peripheral wall and the shape of the peripheral wall is held. When the shield machine 1 is brought near to an arrival shaft, slurry pressure is equalized to total pressure, and recovered to slurry pressure 1 at the time of arrival. The shield machine 1 is removed, a pipe body is pushed into the tunnel T from the starting shaft S and the arrival shaft and the peripheral wall is lined, and slurry in the tunnel T is drained.  Accordingly, excavation is carried out continuously by non-stop without using a segment, and the term of works can be shortened largely because no soil improvement is required.

Filed: 1984-12-17
Abstract: PURPOSE:To always output a peak value regardless of resetting, by resetting one of two peak value holding circuits and, during this time, selecting the output signal of the other. CONSTITUTION:A switch 14 is turned OFF in the first half cycle T1-T2 of an input signal S and a switch SW50 selects the output signal K of a peak value detection circuit 16 and the peak value of the holding signal of the circuit 16 comes to the output M of the switch SW50. The output signal L of a peak value holding circuit 46 follows the input signal S to rise to the peak value of said signal S. Next, a switch SW44 is turned OFF and, when the switch SW50 selects the output signal L of the circuit 46, the peak value of the signal S comes to output M while the switch SW14 is turned ON and the circuit 16 is reset. By this method, when one of the circuits 16, 46 is reset, the output of the other circuit is selected.

Abstract: PURPOSE: To always perform detection of accurate wire delivery length by a method wherein when a hook containing state in the running attitude of a vehicle is detected, computing data of a wire delivery length computing means is reset at a stored wire delivery absolute length. CONSTITUTION: When it is decided that a boom 3 is in a given pattern wherein a crane is runnable, a wire delivery absolute length computing means 40 inputs a wire delivery absolute length, corresponding to a storage pattern, to a wire delivery length computing means 41. Meanwhile, after a wire delivery length data reset means 39 decides the containing state of the boom 3, the containing lock state of a hook 13, and the running state of a vehicle, a data reset signal is outputted to the wire delivery length computing means 41.
