Patent JP-H06103687-A (JP)
Title: Index signal detector
Inventor: NITTA SHUYA
IPC: G11B19/06
Filed: 1992-09-22
Abstract: PURPOSE:To prevent DC-biased components from being generated in a detection sensor output signal and to stabilize an output state by eliminating the influence of leakage flux on the output signal of a detection sensor. CONSTITUTION:At the time of magnetizing the magnetizing part 14 for rotation control of a magnet 10 by a magnetizing coil for the rotation control, the polarity of a voltage to be applied to the magnetizing coil for the rotation control is inverted and magnetized. In such a manner, since the leakage flux from the magnetizing part 14 for the rotation control is offset by the leakage flux of other permanent magnets, the leakage flux for supplying the DC-biased components to the output signal of the detection sensor is reduced and the influence can be eliminated. Thus, the output state of index pulse signals is stabilized, information is read and outputted and writing errors can be prevented from being generated.

Abstract: PROBLEM TO BE SOLVED: To connect this image recording device with a front door slave device and a master device by using an already set wiring without using any special wiring by detecting an incoming signal from the front door slave device to the master device, detecting power supply from the master device to the front door slave device, and recording a video from a monitor camera, and outputting it to a monitor screen by the image recording device connected with a connection line. SOLUTION: When a calling button 12 is depressed, a master device 3 and an incoming detecting part 41 detects an incoming call from a front door slave device 1 through a connection line 2. An image recording device 4 starts at the time of receiving the incoming signal, and receives a videos signal photographed by a monitor camera 11 through the connection line 2, and records it in a recording part 43. The recorded videos signal is outputted through the connection line 2 to the master device 3, and reproduced on a monitor screen 31 of the master device 3. When the monitor screen 31 is turned off by the operation of the master device 3, power supply through the connection line 2 to the front door slave device 1 is stopped. A power supply detecting part 42 detects this, and stops the reproducing operation of the image recording device 4.

Title: Optical heterodyne interferometer
Inventor: KOMATSU SHIGEAKI
IPC: G01B9/02
Filed: 1993-10-08
Abstract: PURPOSE:To provide an optical heterodyne interferometer which is made compact by reducing the number of optical components and is constituted to hardly generate phase distortion by air flows by always bringing two optical paths closer to each other. CONSTITUTION:An acoustooptical modulating element 3 separates laser light by utilizing the Bragg diffraction and, at the same time, modulates high-order modulated light. One of two diffracted light rays of different orders is used as measuring light and the other is used as reference light. Another acoustooptical modulating element 10 modulates the reflected measuring light and reference light respectively reflected from an object 8 to be measured and reference mirror 7 with a frequency which is slightly different from that of the element 3 and generates interference by integrating both light rays. Therefore, the number of optical components used in an optical heterodyne interferometer can be reduced. In addition, since the Bragg angles of the elements 3 and 10 are small, about 7 mrad, the constitution of the interferometer can be made more compact and, since the optical paths for measuring light and reference light can be always brought closer to each other, the phase distortion which is generated by air flows hardly occurs.

Abstract: PURPOSE:To prevent the body of a vegetable cutter from vibration and to prevent the lid thereof from being broken, by locating the outer peripheral side end face part of an opening in a rotary plate at a position which is nearer to the rotational center than the outer peripheral side end face part of a discharge port in a cutter attaching plate. CONSTITUTION:When a motor rotates a rotary plate 22 and a cutter attaching plate 27, a food is sliced and is then dropped through a discharge port 27b and an opening 22a and into the lower part of a container. If the food is cabbage or the like, small pieces of the cabbages which are cut by a rotating slice cutter 22a are scattered toward the outer periphery of rotation under centrifugal force just after it is cut, and are then struck upon the outer peripheral side end face part 22-A of the opening 22a. In this arrangement, if the outer peripheral end face part 22a is formed with an inclined surface, the sliced pieces slide down this inclined surface and discharged downward. Since the outer peripheral side end face part 22a-A of the opening 22a is located near to the rotational center A than the outer peripheral side end face part 27b-A of a discharge port 27-b, no peaks are formed, and accordingly, cut pieces, cut chips or the like are not accumulated.

Title: Power saving controller for inductive load
Inventor: HATANAKA TAKESHI
IPC: G05F1/70
Filed: 1987-10-12
Abstract: PURPOSE:To control the electric power for inductive load and to attain the high energy saving effect by using a auto-transformer type voltage regulator, a DC exciting power supply, a semiconductor switch, a load detecting circuit, and a switch control circuit. CONSTITUTION:An auto-transformer type voltage regulator 24 is set between an AC power supply 12 and an inductive load 18 and an output wiring is formed with use of a serial wiring 46, a serial wiring 50 having the adverse polarity to the wiring 46 and a shunt wiring 48. A DC exciting power supply 28 is set at the input side of the load 18 and an AC reactor 82 takes out the component dependent on the output voltage. While the component dependent on the inductive load current is taken out by a current transformer 80. These components undergo the vector synthesization and rectification and the DC exciting current of a control wiring 26 of a voltage controller 24 is supplied via a semiconductor switch circuit 30. At the same time, an inductive load detecting circuit 32 produces an output signal in accordance with the load state of the load 18. Then a control circuit 34 controls the conduction rate of a switch element 88 of the circuit 30 in response to said output signal. In such a constitution, the load voltage is instantaneously controlled at an optimum level in response to the due state. Thus the load 18 is always driven at the maximum power factor and the high energy saving effect is ensured.
