Title: Industrial robot
Inventor: FUJIWARA KEIJI
IPC: B25J19/00
Filed: 1990-01-11
Abstract: PURPOSE:To make the moving area of a 1st shaft and the installation area of the 1st shaft identical and to bend a cable stably, by arranging so that a cable supported by the cable connectors provided on the 1st shaft and 2nd shaft mutually becomes orthogonal at the position apart more than three times of the minimum radius R of curvature of the cable. CONSTITUTION:The supporting part of a 2nd cable connector 4 is set at the position having the distance three times of a cable minimum radius R of curvature from the extension direction of the cable 5 supported on a 1st cable connector 2. Then, at the time when a 2nd shaft 3 reaches the moving end in the action area of a 1st shaft, the cable whose one end is supported on the 1st shaft up to the lower part of the 2nd cable connector 4, is bent in an orthogonal shape in the 2nd cable connectors direction with the curvature more than the minimum radius R of curvature and the cables other end reaches the 2nd cable connector. Consequently the cable 5 does not pop out excessively from the outline contour of the 1st shaft at the moving end of the 1st shaft.

Title: Sensor for detecting gas
Inventor: HIRAKI HIDEAKI
IPC: G01N5/02
Filed: 1994-01-24
Abstract: PURPOSE:To obtain a sensor for detecting gas which is highly sensitive, can maintain sensitivity for a long time, and can detect reducing gas and noncombustible gas providing a heater etc. for heating a gas-adsorption film. CONSTITUTION:Electrodes 2a and 2b are provided on both surfaces of a crystal vibrator plate 1 and gas-adsorption films 3a and 3b are applied to the surface of the electrodes 2a and 2b. Further, flat-plate shaped ceramic heaters 8a and 8b are installed in parallel with the vibration plate 1 using a lead frame 9 for support which is connected to a lead pin 6c fixed to an insulation support stand 7. When gas is adsorbed to the adsorption films 3a and 3b, the resonance frequency of the vibration plate 1 changes according to the weight of gas, thus detecting gas. At this time, by heating with the heaters 8a and 8b, the adsorption/desorption of gas become reversible, thus preventing gas from being adsorbed and hence sensitivity from being reduced regardless of repeated measurement.

IPC: G03G21/00
Filed: 1995-01-18
Abstract: PURPOSE: To shorten waiting time until a fixed toner image is obtained after a main power source is turned on by controlling so that the time from starting warming-up till starting forming a color toner image in a color image forming mode may be shorter than the time till starting forming a monochromatic toner image in a monochromatic image forming mode.

The CPU performs arithmetic operation for predicting the timing of completing warming-up and predicts warming-up completing time when thermal fixing is executed by a thermal fixing device 70. The CPU obtains the timing of performing thermal fixing with the temperature rise of the thermal fixing device 70 from the data on the warming-up necessary time in a memory, and sets it as the warming-up completing time after adding a safety factor thereto. Furthermore, the timing of starting forming a color image is set by performing inverse operation.

IPC: F22G5/04
Filed: 1978-01-23
Abstract: PURPOSE: To prevent corrosion of a heating tube of a superheater due to high temperature thereof by constituting the heating tube such that portions thereof at which the temperature of the tube wall gets relatively high have a reduced diameter compared with the remaining portions of the heating tube.  
     CONSTITUTION: A boiler 1 consists of a furnace section 1A having a spray burner 6 provided thereto, and a superheater 2 to which a set of generating tubes 4 are connected. Combustion causes an ash bed 7 of inorganic salts to be formed on the bottom of the furnace section 1A. The furnace section 1A has a sufficiently large magnitude, compared with a conventional boiler which utilizes fossil fuels, to assure satisfactory evaporation of water and to prevent such inorganic salts from carrying over to a convection heating surface of the superheater 2. Accordingly, gas at the entrance of the superheater is at a low temperature. The superheater 2 extends over the furnace section 1A by way of a nose baffle 5 in order to increase the area of its heating surface. Part of a heating tube 8 positioned at a portion of the superheater 2 which extends from the nose baffle 5 has reduced diameter 8A compared with the remaining part of the heating tube 8 so that flow is accelerated in the reduced diameter section of the heating tube 8 to thereby reduce the temperature of the tube wall of such section of the heating tube 8.

Abstract: PURPOSE:To prevent the exhalation of putrid smell and improve sanitary and operating efficiency by detecting the temperature in a chamber and reducing the pressure in the chamber in accordance with the temperature. CONSTITUTION:Normally, pressure in a chamber is detected by a pressure sensor PS and a vacuum pump P is operated at above an upper limit value while stopping the pump P at below a lower limit value to keep the pressure in the chamber at a required reduced pressure condition.
