Title: Measuring instrument for axial elongation quantity of rotary body
Inventor: MATSUDA YUKIO
IPC: G01B21/00
Filed: 1987-06-16
Abstract: PURPOSE:To easily measure the axial elongation quantity of a rotary body at an optional position with high accuracy over a wide measurement range by providing a mark which is fitted slantingly to the axial direction of the rotary body. CONSTITUTION:Marks which are parallel to, for example, the shaft of the rotary body are drawn on the mark 2 which is slanted properly to the axial direction and a reference mark 3. Sensors 4 and 5 each generate one output for one turn every time the marks 2 and 3 pass in front of the sensors 4 and 5. Here, the sensor 5 generates its output signal invariably at a reference mark position regardless of the elongation of the shaft 1, but the output signal of the sensor 4 varies in time interval with the output signal of the sensor 5 because it moves axially as shown by a dotted line in a figure as the shaft 1 is elongated. Therefore, the elongation quantity of the shaft 1 is calculated from the time difference from a measurement time in a no- elongation reference time, the rotating speed (found from the interval between the output signals of the sensors 4 and 5), and the external diameter of the shaft 1. Further, the sensors can be arranged in parallel to the rotary body, so a measurement is taken at an optional position.

Title: Heat fixing roller
Inventor: ANZAI TOSHIKI
IPC: G03G15/20
Filed: 1981-09-22
Abstract: PURPOSE:To minimize the quantity of heat absorbed by a press-contacting roller during copying, and easily control the set temperature of a heat fixing roller without reference to ambient temperature, etc., by preheating the press- contacting roller side sufficiently before the copying is held in readiness. CONSTITUTION:When the surface temperature of a heat roller 1 attains to set temperature T1, the output of a comparator 7 is inverted from ''H'' to ''L'' and the output of an AND gate 18 is inverted from ''H'' to ''L'', so a binary counter 8 goes up by one. Then, a transistor (TR) 10 turns on to power up a main motor relay 11, thereby rotating the heat roller 1 and a press-contacting roller 3. Then when the surface temperature of the heat roller 1 attains to the set temperature T1 again, the binary counter 8 goes up to generate a count output O2 of ''2'' with a level ''H''. Further, a count output O1 goes down to ''L'', so the main motor relay 11 is powered down to stop the rotation of the heat roller 1 and press-contacting roller 3.

Filed: 1995-06-16
Abstract: PURPOSE: To grow a single crystal having stable composition and excellent quality of a readily dissociating and evapotranspiring compound semiconductor by forming a heating region having a temperature at one end side higher than another end side in a furnace and growing a single crystal from a raw material melt in a specific state by a simpler construction. CONSTITUTION: A heating region having upper temperature higher than lower part is provided in a furnace body 1, and on the other hand, a first crucible 10 receiving a raw material for single crystal growth and a second crucible 11 receiving a raw material containing about the same composition as the raw material for single crystal growth are received in a sealing vessel 12 so that the second crucible 11 is placed on the upper part of the first crucible 10. A single crystal is grown from the raw material melt in the first crucible 10 by raising and lowering a temperature of the sealed vessel 12 in the heating region.  The raw material in the second raw material-receiving vessel preferentially proceeds the dissociation according to the temperature rising and a gas of a high dissociation pressure component generates in the sealed vessel by the single crystal growing method of the compound semiconductor. By the gas, the dissociation in the first raw material receiving vessel is suppressed, and therefore, any of the components is suppressed as well as possible in the first raw material receiving vessel and a single crystal of excellent quality having an intended composition is grown.

Abstract: PURPOSE:To provide a speaker system whose performance is easily improved by arranging a capacitive element in series between a fixed electrode and a drive signal supply source in an electrostatic speaker so as to form equivalent capacitance and resistance component in the case of application of an insulation film to the fixed electrode. CONSTITUTION:In an equivalent circuit where insulation capacitors 40A, 40B are connected in series between fixed electrodes 4A, 4B and terminals TF, TR, a capacitance of the capacitors 40A, 40B and that of an air gap C are expressed respectively as CC, CA. Furthermore, the resistance component of the capacitors 40A, 40B and a surface resistance of the component member of the air gap C are expressed respectively as RC, RS. Thus, the insulation capacitors are applied to the speaker to obtain the state equivalent to application of insulation paint to the fixed electrodes 4A, 4B electrically. Thus, the insulating paint is not required to reduce the cost and a uniform sound pressure due to a uniform air gap and an insulation breakdown voltage is improved and the performance is improved with a simple configuration.

Filed: 1982-08-30
Abstract: PURPOSE:To enable the temporary restarting when a pulse generator which generates a reference pulse goes out of order, by generating the spurious reference pulse in place of the reference pulse of said generator when the pulse generator goes out of order. CONSTITUTION:When the 2nd pulse generator 4 goes out of order, the operation is immediately stopped. A fault detector 16 operates upon lapse of a prescribed time, and a control circuit 17 enables the operation by which an engine is restarted. The pulses from the 1st pulse generator 1 are counted with the 2nd counter 18 and the counter is reset at (180). Such operation is repeated and at the same time, the time between each pulse signal is successively measured with a detection circuit 19 for angular speed and is stored in the address of a memory 20 corresponding to the count number of the counter 18. The address storing the min. value among the respective times is selected by an arithmetic circuit 21 for the min. value. A spurious reference pulse signal is generated from the 2nd discrimination circuit 22 every time when the numerical value of the 2nd counter 18 attains the value equal to the value corresponding to the storage address for the min. value and is outputted to the 1st counter 11, whereby the operation of the engine is resumed.

IPC: H01L29/10
Filed: 1979-11-21
Abstract: PURPOSE:To control gate trigger currents in excellent reproducibility by a method wherein a P3 layer, a section located under an N4 layer, is divided into a thin P<+> type layer and a P<-> type layer, and the four layer structure of P1N2P3N4 is changed into P1N2P3<->P3<+>N4 structure, in a thyristor with the four layer structure. CONSTITUTION:P type impurities are diffused to both surface and back sides of an N type semiconductor substrate 2 functioning as an N2 layer to form a P<-> layers 32 and a P1<-> layer 12. P type impurities are similarly diffused to the layers 32 and 12 to each form a P3<+> layer 31 and a P1<+> layer 11. Normally, a P3 layer made up on a substrate 1 is divided into the P3<-> layer 32 and the P+ layer 31, and a P1 layer built up to a lower surface of the substrate 2 is also divided into the P<-> layer 12 and the P1<+> layer 11 though this operation is not a main object. An N4 layer is diffusion-formed to one section in the P3<+> layer 31 thinning the thickness of the layer 31 remaining in a lower section of the layer 31, and a cathode electrode is attached to the N4 layer, a gate electrode 6 on an exposing surface of the layer 31 and an anode electrodes 5 further on the back of the layer 11 respectively. Thus, gate trigger currents are controlled at several muA-several hundred muA in excellent reproducibility.
