Title: Centrifugal compressor
Inventor: IMAKIRE KOUICHIROU
IPC: F04D27/00
Filed: 1980-10-07
Abstract: PURPOSE: To enable smooth control from light-load to heavy-load condition by setting the inclining angle of inlet guide vanes so as to adjust to the signals detected on the temperature of air, passing through the inlet guide vanes, and the rotating speed and the delivery pressure of a compressor.  
     CONSTITUTION: The pressure coefficient of a cmpressor 1 is determined by three factors: air suction temperature, the pressure ratio between compressor delivery pressure and atmosphereic pressure, and compressor revolutions. Therefore, as is shown in the drawing, the temperature of air 5 passing through guide vanes 2 is detected by a temperature detector 10, and the rotating speed and the delivery pressure of the compressor 1 are detected by a speed detector 11 and a pressure detector 12, respectively. These detected signals are input into a control device 13 to calculate the pressure coefficient and this calculated value is used to set the inclining angle θG of the guige vanes 2, thus smooth control from light-load to heavy-load condition is attained.

Title: Insulated electric wire
Inventor: YAMAZAKI TAKANORI
IPC: H01B7/02
Filed: 1987-06-03
Abstract: PURPOSE:To obtain an insulated electric wire excellent in radioactive ray resistance at a low cost by providing an insulating layer made of polyether etherketone resin on a core conductor and coating polyimido resin varnish on the insulating layer. CONSTITUTION:An insulating layer made of polyether etherketone resin is provided on a core conductor, and polyimido resin varnish is coated on the insulating layer. The polyether etherketone resin has thermoplasticity and can be extrusion-molded. It is also excellent in radioactive ray resistance and has the resistance up to 100 MGY in nitrogen with no air in particular. It has no resistance, however, against radioactive rays exceeding 10 MGY in the air, thus polyimido resin varnish is coated on a polyetherimido resin layer to shield the air with this varnish layer, thereby the resistance is provided against radioactive rays exceeding 10 MGY in the air.

Title: Detecting circuit for breaking of wire
Inventor: IMAI HIROHISA
IPC: H02H3/00
Filed: 1985-06-26
Abstract: PURPOSE:To easily detect the breakingof a wire even when an element to be detected requires a small resistance value or large current by detecting the breaking of the wire when the element to be detected is off with a changeover contact open. CONSTITUTION:A resistance circuit 3 consists of the element 1 to be detectd, a detecting resistance 2 connected to the element 1 in series, and the changeover contact 10 connected to the resistance 2 in parallel. A wire breaking decision circuit part 5 detects the breaking of the wire of the element 1 from the voltage across the detecting resistance 2 when the changeover contact 10 is broken. Thus, when the breaking of the wire of the element 1 is detected, the changeover contact 10 is broken to detect the breaking of the wire and when the breaking of the wire is not detected, the changeover contact 10 is closed to put the element 1 in normal operation, so even when the element 1 has a small resistance value, there is not such as adverse influence that a current decreases owing to the detecting resistance and even when the element 1 requires a large current in operation, the breaking of the wire is detected without using any large-power detecting resistance.

Title: Liquid crystal-optical shutter

IPC: G02F1/13
Filed: 1982-08-12
Abstract: PURPOSE:To obtain a liquid crystal-optical shutter which is easily connectable to external circuits, by sandwiching a liquid crystal between a substrate having signal electrodes disposed zigzag and ground electrodes disposed apart at a slight spacing therefrom and a substrate having a common electrode. CONSTITUTION:Signal electrodes 21 are disposed zigzag on a transparent substrate 20, and are connected to external circuits on both sides of the substrate 20. Ground electrodes 22 are formed on the substrate 20 apart at a slight spacing from the electrodes 21. A common transparent electrode 23 is formed on the substrate 20 facing to the same, and a nematic liquid crystal 24 having positive dielectric anisotropy is disposed between both substrates 20. If a sinusoidal voltage Vc is applied to the electrode 23 and the electrodes 21 are held grounded like the electrodes 22, the liquid crystal 24 are oriented perpendicularly, thereby having a dark (closed) state between crossed nicols 26 and 27. When the voltage approximate to Vc is applied to the electrodes 21, the liquid crystal is oriented in a transverse electric field direction, thus having a bright (open) state. Since the electrodes 21 which are disposed zigzag are used, the connection to external circuits is easy.

Abstract: PURPOSE:To obtain a clean body to be treated while preventing the contamination of the rear of an object to be coated due to the generation of particles accompanying friction by connecting a support stand to a rotary drive mechanism through a transmission means buffering a change of a rotational speed to transmit the same. CONSTITUTION:The chuck 4 connected to a motor 1 is connected to the rotary shaft 2 of the motor 1 through a transmission means 3 buffering a sudden change of a rotational speed such as a fluid joint or a spring. Therefore, even when a sudden change is generated in the number of rotations of the motor 1, the acceleration applied to the chuck 4 is reduced and the force sucking a wafer W by the chuck 4 is made relatively larger than the force received by the sudden change in the number of rotations to certainly suck the wafer W and the generation of the shift of rotation accompanying the sudden change of the number of rotations between the wafer W and the chuck 4 is prevented. As the result, the rear contamination of the wafer W due to the generation accompanying the friction between the chuck 4 and the wafer W is eliminated and a clean body to be treated can be prepared.

Title: Separate type ejector plate mechanism

IPC: B29C45/40
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To improve an efficiency of an ejector pin replacing operation by providing an ejector plate independent of a plate for mounting a return pin. SOLUTION: Since a plate 1 has a through-hole 12, an ejector upper plate 2 for preventing rising of an ejector pin(EP) 9 and a bolt 5 can be removed without removing a bolt 4. Since a plate 3a for fixing the EP 9 and a plate 3b for fixing a return pin 8 are independent structures, the EP 9 can be replaced by removing only the bolt 5 and the plate 2. In replacing the EP 9 in particular, the bolt 5 is removed, the plate 2 is removed, the EP 9 is drawn, the plate 3a is removed, an insert is replaced, and the EP 9 and the ejector plate are replaced to meet the molding. Since the separate plate 3b is not removed, a spring is not suppressed, and no influence is affected to a positional accuracy of the mold. Thus, a replacing work of the EP 9 is simplified, and its working efficiency can be improved.

Abstract: PURPOSE:To perform scan and reproduction by always keeping the on-track of a reproducing head on a recording track by detecting the change of the recording position of a signal on the recording track automatically in the reproduction by an off-track detection circuit. CONSTITUTION:At the off-track detection circuit 120, off-track data 130 outputted from an off-track arithmetic circuit 111 is supplied to a terminal 701.

An H-SW signal is inputted to an adder circuit 703 via a terminal 707, and the off-track data per one scan of a head is integrated. At a comparator 704, an obtained integration value is compared with a preset value 705, and when the integration value is larger than the preset value 705, the signal 125 is outputted from a terminal 706 to find the reference value of the tracking control again.
