Title: High frequency oscillation type proximity switch
Inventor: MATSUOKA YASUSHI
IPC: H03K17/95
Filed: 1991-03-07
Abstract: PURPOSE:To identify a fault even when one of a twisted wires is disconnected by providing a monitoring circuit employing at least one coil element wire of a coil and detecting the disconnection as a voltage change and a fault detection circuit to detect the disconnection based on a change in the output level of the monitoring circuit to the switch. CONSTITUTION:The monitoring circuit 21 is connected to one terminal of a detection coil 20. A monitor circuit 21 is used to detect a broken coil wire and its output voltage is compared with a reference voltage by the comparator 26 of a fault detection circuit 22 and when the fault of the coil is detected, a fault detection signal is outputted externally from an output circuit. A part 24a of the coil element wire of the coil 20 is not used for an oscillation circuit 11 but used for detecting the disconnection and is connected to a power supply via a resistor R4. End parts of other coil element wires 24b-24g are collected and connected to the oscillation circuit 11. When a part of the coil 20 is disconnected since lots of coil wires are wound on a spool, it is highly possible the coil element wire 24a is disconnected simultaneously and the broken wire is detected with high probability.

Filed: 1990-03-19
Abstract: PURPOSE: To easily execute assembling without deteriorating an optical connection state even as against temp. change by directly fixing an electric and optical signal converter and an optical fiber on the main surface of a supporting material and mutually and optically connecting them. CONSTITUTION: The optical output port of a laser diode is at a position about 3μm under the upper front surface of a die 14 and the die 14 is connected to a metallic layer area 8 by a wire.

Title: Electrostatic capacity type force sensor
Inventor: MORIMOTO HIDEO
IPC: G06F3/038
Filed: 1994-04-07
Abstract: PURPOSE:To obtain an electrostatic capacity type sensor having an excellent operating sense when it is used as the operating part of a cursor indicated on a display, by providing upper and lower substrates and an electrode part. CONSTITUTION:The sensor consists of an upper substrate 1, lower substrate 2C, operating axis 3 and electronic device 4 in principle. A spacer 11, that is circular and thicker than an electrode part, is placed between an arrangement area and hole 10, so that the electrode part Cx+ to Cy- may not be kept in contact with a lower substrate 2 in a status where an external force does not work against the axis 3. Then, when the upper end of a thick axis 31 is pressed by finger, the substrate 2 is brought into contact with a welled part 52a by the pressing force of a compression coil spring 33B. In this status, when an inclining force is applied to the axis 3, the attitude of the substrate 2C is changed. Therefore, compared with a conventional sensor that deforms a diaphragm part, its inclining amount becomes larger, resulting in an excellent operating sense.

Filed: 1990-03-22
Abstract: PURPOSE:To renormalize a tracking error signal in an area only for reproducing to satisfactorily perform the tracking control in this area by detecting the area only for reproducing on a optical disk to reset the peak holding operation of a sum signal. CONSTITUTION:Detecting means 21 to 25 which detect the area only for reproducing on the optical disk and a means 26 which resets the peak holding operation of the sum signal by the detection signal of these means and holds the peak of the sum signal in the area only for reproducing are provided. The peak holding operation of the sum signal is reset at the time of detecting that an optical head enters into the area only for reproducing when travsersing a track. Consequently, the peak of the sum signal is held again in the area only for reproducing, and its value is used to normalize a tracking error signal again. Thus, the tracking error signal is automatically correctly normalized at the time of entering to the area only for reproducing.

Title: Belt-shaped material tiering device
Inventor: OKUYAMA GOJI
IPC: B65H39/16
Filed: 1985-04-03
Abstract: PURPOSE:To improve the accuracy of tiering, by using a converting guide furnished along a bisector of the crossing angle between two running belt-shaped materials, and transferring one belt-shaped material over the other depending on the detected data of the both lateral positions in the down stream. CONSTITUTION:A belt-shaped material P is converted its direction by 90 deg. by the roller of a converting guide 7, and converted again by 90 deg. by the roller 14 of a converting guide 8 at the crossing with the other material Q, and then runs parallel to the material Q thereover. Since detectors 29 and 22 are constantly checking the lateral positionings of belts Q and P respectively, a control system depending on signals from the detectors acts to move piston rods 33 and 34 of cylinders 31 and 32 to activate the converting guide 8, if either of the two belts begins to move in a zigzag direction. As a result, the direction converting point of the belt-shaped material P is converted laterally to the belt Q to make the belt-shaped material P follow the belt-shaped material Q, to be tiered in a high accuracy maintaining a desired relative positioning.

Abstract: PURPOSE:To make the surface temperature of a flat heat generator uniform and improve the durability of the heat generator by setting a heat generator element between an inorganic insulating sheet and a heat diffusing sheet and uniting the resulting body by heating and pressing. CONSTITUTION:A heat generator element 1 made of a metal foil is sandwiched between an inorganic insulating sheet 2 and a heat diffusing sheet 3 and the resulting body is united by heating and pressing to give a panel heat generating body, wherein the sheet 2 is prepared by adding an inorganic adhesive 2a to an inorganic insulator 2a of such as mica powder, etc., and forming the mixture into a sheet and the sheet 3 is prepared by adding an inorganic adhesive 2b to ceramic 3a of such as aluminum nitride, etc. Consequently, since the inorganic insulating sheet 2 and the heat diffusing sheet 3 contact with and fix in the whole surface of the heat generator element 1 of a metal foil with high resistance by heating and pressing, no local heating occurs and the heat from the heat generator element 1 is diffused in the heat diffusing sheet 3 having high thermal conductivity and high insulating resistance. The diffused heat is transmitted immediately to the inorganic insulating sheet 2 and the surface temperature is kept uniform and durability of the heat generating body is improved.
