Title: Servo motor speed detecting device
Inventor: HORIGUCHI SHIRO
IPC: H02P29/00
Filed: 1992-01-14
Abstract: PURPOSE:To provide a speed detecting device capable of detecting the rotating speed of a servo motor with accuracy and the speed closer to the actual speed at the sampling time. CONSTITUTION:The clock pulse number in each output cycle of a pulse encoder PG is counted by a counter 13, and the count value is stored in a memory 19. The encoder output pulse number in a sampling cycle is counted by an output pulse counter 16. When a sampling signal is inputted, a CPU 18 determines the n-number (n>=2) of encoder output pulses immediately before sampling on the basis of the encoder output pulse number in the sampling cycle. The clock pulse count value in each cycle of n-number of output pulses is read from the memory 19, and the sum is computed. The motor rotating speed is then computed using the inverse number of the average cycle based on the sum on the n-number of encoder output pulses immediately before sampling.

Title: Method for measuring double-seaming part of can lid
Inventor: IDA YASUTO
IPC: G01B15/00
Filed: 1987-01-14
Abstract: PURPOSE:To accurately measure a dimension, by arranging a reference block at a position to be measured in parallel to said position and simultaneously picking up the images of both of an article to be measured and the reference block by X-ray fluoroscopic photographing. CONSTITUTION:The dimension and internal dimension of the double-seaming part 7 of a can body and a can lid are measured by X-ray transmission photographing. When the width of the double-seaming part 7 is set to W and the diameter thereof is set to D, a can is placed on a horizontal place so as to be inclined by sintheta>=W/D so that the area 8 to be measured of the double- seaming part 7 is directly photographed. A reference block 9 is arranged at the same height position as a surface to be measured, and the fluoroscopic image of the area 8 to be measured of the part 7 and that of the reference block 9 are formed on an image pickup surface. X-rays from an X-rays apparatus 1 are projected on the image pickup surface 4 of an image pickup tube 3. By performing dimensional correction on the basis of the size of the reference block 9 even when the position of the area 8 to be measured of the part 7 is different in the height direction, accurate measurement becomes possible.

Title: Matrix display device
Inventor: KIKUCHI ISAKO
IPC: G02F1/133
Filed: 1987-01-13
Abstract: PURPOSE:To obtain a high display grade at a low cost by laminating 1st conductor layers having spacings, 1st resin layers, semiconductor layers consisting of a compd. of arsenic (As) and sulfur (S), 2nd resin layers and further 2nd conductor layers successively on a substrate. CONSTITUTION:A display medium is sandwiched between a nonlinear two- terminal element array having the composite layers consisting of the 1st conductor layers 2 which have the spacings, the 2nd conductor layers 6 which are provided in plural pieces each with each of the conductor layers 2, the 1st resin layers 3 which are interposed between the 1st conductor layers 2 and the 2nd conductor layers 6 and are electrically cascade-connected, the semiconductor layers which consist of the compd. of the arsenic (As) and sulfur (S) and the 2nd resin layers 5 successively on the substrate 1 and the 2nd substrate having band-shaped electrodes. A nonlinear current-voltage characteristic is, therefore, realized and the improvement in contrast characteristic is permitted. Since the specific dielectric constant of the compd. of the arsenic (As) and sulfur (S) forming the semiconductor layers 4 is as small as <=10, the formation of the nonlinear element to a relatively large shape is possible and the improvement in the yield is expected.

Title: Driving method of pickup arm
Inventor: KIKUCHI TAKASHI
IPC: G11B21/12
Filed: 1982-01-18
Abstract: PURPOSE:To continue the drive control of an arm surely, by restoring the arm to a rest position forcedly with a mechanism drive system, if the pickup arm is jumped out to the outside of the driving range of an electromagnetic driving system. CONSTITUTION:In starting the pickup arm at the rest position A with an operation button of a CPU (not shown) after the designation of a recording, the arm is turned with a mechanism drive system 7 to a position C, and the electromagnetic force DD drives the arm from a position D to a B. At the DD drive, a photocoupler at the tip of the arm 5 is activated and every time the inter- music is detected, a position sensor interlocked with the arm gives an address to the inter-music and the address is stored in the CPU. In detecting the size of the disc, the DD drive is reversed, the designated address is searched and the arm is fallen down. When a position sensor detects that the arm 5 is at the outside of the region of the DD driving system due to any cause, the arm 5 is restored to the rest position A forcedly for lead-in again. Thus, the driving of the arm is controlled surely.

Title: Shape detection
Inventor: HIROHATA KAZUHIRO
IPC: G01B7/00
Filed: 1980-01-23
Abstract: PURPOSE:To compensate a detection error for making precise detection by a precess wherein from the maximum value of the output signals of a shape detection cell set up in the direction of the width of rolled material each output signal is subtracted to detect the shape in the direction of the width using the value gained by the division of said value by the minimum value. CONSTITUTION:The lengthwise voltage signals VR1-VR3 and the transverse voltage signals Vr1-Vr3 of the rolled material gained by the each shape detection cells 21-23 are subtracted by the subtractors to gain the signal corresponding to the tention value sigmai. The maximum signal gained by the selector 34 is given to the subtractor, each tention signal is subtracted and the signal corresponding to the tention fluctuation quantity DELTAsigmai are given to the dividors 38-40. On the other hand the minimum value signal of the minimum value selector 41 is put into the dividers 38-40 to divide DELTAsigmai by said minimum value and the output thereof is given to the shape arithmetic unit 42 to detect the traverse shape of the rolled material. Accordingly the detection error is compensated to make it possible to perform detection with high precision.

Title: Current-voltage conversion circuit
Inventor: KITAJIMA TOMOKAZU
IPC: H01L27/04
Filed: 1992-01-16
Abstract: PURPOSE:To operate a current-voltage conversion circuit with a low voltage in a simple circuit constitution and to prevent chattering of the output by adding a current hysteresis dependent upon a current mirror circuit. CONSTITUTION:When an input current IIN rises from 0 to >=10muA (going path), an output voltage VOUT rises; and when it is equal to a voltage VBE of a transistor TR 3, a current mirror circuit 4 starts the operation. Therefore, the voltage VOUT quickly rises to reach a maximum value, and the displacement point of the voltage VOUT in the going path corresponds to the time when the current IIN is 10muA. In the case of the return path of reduction of the current IIN to 0, a collector current I2 of a TR 2 has a maximum value I2 (15muA) still when the current IIN is 10muA. Consequently, a base current IB does not flow to an output TR 1, and the voltage VOUT does not drop. It starts to drop when the current IIN is reduced to 5muA, and the current I is reduced in accordance with the drop of the voltage VOUT, and the voltage VOUT quickly drops. That is, the displacement point in the return path corresponds to the time when the current IIN is 5muA, and this displacement point is different from that in the going path, and a hysteresis is obtained.

Title: Dehydrating method for water-containing coal
Inventor: OOI SHIYOUICHI
IPC: C10L9/08
Filed: 1981-01-20
Abstract: PURPOSE: To dehydrate water-containing coal at a low temperature under a low pressure in a short time, by heating solvent slurry of the water-containing coal to a specific temperature or lower under a pressure, cooling it to a specific temperature or lower and subsequently introducing it into a separating device under a specific pressure or lower.  
     CONSTITUTION: Water-containing coal and a solvent are mixed to be slurried on a grinder 1, and the slurry is pressurzed by a pump 7 before heated to 150W 350°C by a preheater 2. Water contained in coal is readly dispersed into the solvent, and coal itself becomes lipophilic, so that the coal hardly absorbs water. Subsequently, the slurry is cooled to 200°C or lower by running it through a heat exchanger 3 or without doing so, and then the slurry is separated into one solvent flow containing a large amount of water and the other solvent flow that has been dehydrated and contains coal. The former slurry is sent to a water layer-separating tank 5, in which the slurry is left to stand under a pressure higher than the saturated vapor-pressure of water to separate the water layer and the solvent layer. The latter slurry is introduced into a gas-liquid separator 6, in which the remaining moisture in the slurry is evaporated by the heat energy of this flow, thereby producing much less moisture-containing slurry. This slurry is used as a fuel or as a raw material for coal liquefaction.

Filed: 1986-01-14
Abstract: PURPOSE:To prevent a deterioration in physical properties and a failure in external appearance due to gripping of a molding material, by so constituting the titled device that a top force is constituted clampably and breakably to a bottom force with a mold device for molding of a wheel of a motor car or a motorcycle and a core mold is so constituted that the same is made movable in two directions such as a vertical direction and diametral direction. CONSTITUTION:A cavity space is formed by breaking a top force 1 and moving cores 3, 4 upward. Cylindrical molding materials 14, 15, 16 are inserted into the cavity space. The cores 3, 4 are lowered under a state wherein they are kept clamped as they are. With this construction, the cavity space is filled with the molding material. Then molding is performed by clamping the top force 1 after the molding material 14 has been bent so as to press the molding material 14 against the cores 3, 4. When molding is completed, the top force 1 is broken and the cores 3, 4 are broken by moving them in a widening direction of the diameter. A molded thing is extruded through the force under this state. A core mold is prevented from gripping the molding material as the cavity space is filled with the molding material by lowering the core mold while the same is being kept closed.
