Title: Torque detector
Inventor: KITA TOORU
IPC: G01L3/10
Filed: 1983-10-19
Abstract: PURPOSE:To enable constantly stabilized and highly accurate torque detection, by attaching an elastic supporting member for fixing a holder onto a tube wall in such a way that the holder can vibrate in the direction of a specimen shaft. CONSTITUTION:A steering shaft 6 is arranged through a steering column 10 that surrounds its periphery and an elastic supporting member 11 of rubber material is mounted in a through hole formed on a part of the periphery of the column 10 in such a way that the through hole is closed. Further, in the middle on the inside surface of the member 11, a flange 12 attached to a holder 9 is fit and thus, as the holder 9 is supported on the column 10 through the elastic supporting member 11, the holder 9 makes a displacement in accompaniment of rotation of the steering shaft 6. Thus, a gap between steering shaft 6 and magnetic head 7 is kept always constant regardless of distortion of the steering shaft 6, concentrieity, inelination, and strain of the steering column 10 itself, etc., and stabilized and highly accurate torque detection becomes available.

Title: Semiconductor radiation detector
Inventor: SATO NORITADA
IPC: H01L31/09
Filed: 1984-09-19
Abstract: PURPOSE:To allow the number of electric current pulses to be independent from the energy of gamma-rays by a method wherein the shape of a depletion layer in a plane parallel to the surface of a substrate is so formed that it is provided with several lengthy protrusions and the distance between the edge of the semi conductor substrate and the periphery of the depletion layer is made equal to the average trajectory of the secondary electrons generated by the gamma-rays with their energy at the highest. CONSTITUTION:At the central portion of a P-type silicon substrate 1, an N-type region 2 is formed wherein rectangular protrusions 22 radiate from a circle 21. Application of an inverse bias to the P-N junction formed between the substrate 1 and region 2 results in the creation of a depletion layer 5. Secondary electrons 71, produced due to gamma-rays with the maximum of their intensity at the narrowest portion outside the depletion layer 5, go at a high probability into the depletion layer 5 surrounding the N-type region 2 provided with a long peripheral length. The secondary electrons 71 contribute to the creation of electron-hole pairs in regions 12, thereby reducing dependency of a radiation detector in respect of sensitivity upon the intensity of the gamma-ray energy.

Title: Carrier for electrophotographic developer
Inventor: SHINOKI MASAHITO
IPC: G03G9/107
Filed: 1987-08-07
Abstract: PURPOSE:To impart high electrification property and to improve resistance bearing environmental condition by using a specified styrene-acrylic resin. CONSTITUTION:The carrier to be used here is composed essentially of the resin and a magnetic powder dispersed in it. Said resin is the styrene-acrylic type resin having an acid value of <=1 and a melt index (MI) of <=50g/10min at 175 deg.C under 5,000g load. It can be produced by polymerizing styrene or its derivative, (meth)acrylate, (meth)acrylic acid, and other monomers when needed. If the acid value is more than 1, change of electrification potential between summer and winter increases, and if MI exceeds said value, dispersion of the magnetic particles does not become uniform, and initial electrification potential deteriorates.

Abstract: PROBLEM TO BE SOLVED: To improve smoke protection by constituting the shutter so that a panel is moved from the closed posture to the opened posture in accordance with the condition that the guide rail or the shutter curtain contained in a ceiling container is hung down. SOLUTION: A shutter 1 and a guide rail 6 are contained in a ceiling container 2 when the opening is opened and hung down from a lintel 5 when it is closed. This lintel 5 can be closed by a freely openable/closable panel 13. And the panel 13 is opened when the shutter curtain 1, and the guide rail 6 are hung down from the lintel 5. In this time, the panel 13 closes the upper part of the opening to form a smoke protection division. And when the guide rail 6 is transferred from the horizontal posture to the vertical posture, the panel 13 is automatically moved from the closed posture to the opened posture. In this way, a fireproof shutter excellent in smoke protection can be obtained.

Title: Signal processing method and reproducing device using the same
Inventor: MUTO HIROSHI
IPC: H03H15/00
Filed: 1992-07-23
Abstract: PURPOSE:To automatically perform waveform equalization according to signal quality by finding an equalization error from a delay signal, a difference signal, and a ternary decision signal generated from an output signal, and feeding it back to an equalization constant for weighting. CONSTITUTION:Three signals having the time difference T of delay signals B, C, and D are obtained for the reproduced signal A of the evaluation pattern of a recording medium through equalization delay element trams 31a-31c. Subtracters 32a and 32b multiply them by the equalization constant for weight and an adder subtracter 33 substrates the result from an equalized delay signal C to obtain an equalized waveform output signal E. Delay elements 41a and 41b obtain Yn and Yn-1 from a sampled value Yn+1 of the signal E with delay signals G and F and a difference signal J is obtained from an adder subtracter 42. For Yn, a ternary decision unit 43 obtains Xn of '+1, 0, -1' and obtains Xn-2 through FFs 41a and 41b, and a multiplier 45 finds a signal I. A multiplier 46 calculates a specific equalization constant K from the signals J and I. The constant K is held at a holding part 48 and the attenuation quantities (weighting of attenuators 32a and 32b are varied with a control signal. Consequently, a highly precise equalized waveform corresponding to the signal quality is obtained.

Filed: 1989-07-28
Abstract: PURPOSE:To improve the repeating accuracy of holding operation by allowing holding parts to hold a refraction element forming notched parts opened like V shapes on the opposed parts of its side parts on the notched parts. CONSTITUTION:A pair of holding parts 1a forming semicylinders are formed on holding members 1 so as to be mutually opposed, at the time of holding the refraction element 3 by the holding parts 1a, the notched parts 3a forming the V shapes slide the curved faces of the holding parts 1a, and on the holding position, each notched part 3a is contacted with the holding part 1a at almost fixed two positions. Thereby, the refraction element 3 comes into contact with the holding parts at 4 positions of the notched parts and held in the dynamically balanced state. Consequently, the refraction element 3 can be stably held almost at the fixed positions and the repeating accuracy in the holding operation of the holding members 1 can be improved.
