Title: Image forming device and electric conduction controller
Inventor: TSURUNO KUNIO
IPC: H05B3/00
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately perform an electric conduction control. SOLUTION: Electrical energy is converted into heat energy by a halogen heater 2. The halogen heater 2 is energized by a heater control circuit 6 so as to control the generation of the heat energy. A toner image formed on a photoreceptor drum based on an image signal is melted by the heat energy and fixed to a recording material through a fixing roller 1. A thermistor 6 arranged opposite to the fixing roller 1 is provided with impedance characteristics corresponding to a temperature. By having a constitution of a disconnection detection resistance 7, a high temperature detection resistance 8, switches 9 and 10, voltages V1 and V2 corresponding to the impedance of the thermistor 5 are generated.  The voltages V1 and V2 are compared with reference voltages Vref1 and Vref2 from a disconnection comparison voltage supply 14 and a high temperature comparison voltage supply 13 by a high temperature comparator 11 and a disconnection comparator 12. In accordance with the comparison results, the electric conduction to the halogen heater 2 by the heat control circuit 6 is controlled by a system control microcomputer 15.

Title: Measuring device for propelling direction of underground excavator
Inventor: TANIMURA KOUICHI
IPC: G01C21/00
Filed: 1981-02-28
Abstract: PURPOSE:To make the reading of the scale on the leading end side of an excavator easy by changing the position of one target and reading the scale of said target at two places. CONSTITUTION:When the propelling direction of an excavator changes its angle, for example upward, that is, in the state in which a propulsion line B deviates from a reference propulsion line A, a target 16 is moved remotely in a forward or a backward direction by a set distance L. In parallel with this, the scales h1, h2 from the center P of the target 16 of that time are read on the outside with a telescope 20 placed along the line A, and the angle change of the line B with respect to the line A is calculated on the basis of the detected scales h1, h2 and the set distance L. Thus, in the stage of reading the scale on the reading end side of the excavator, nothing exists in the front part thereof and therefore the reading thereof is easy.

Title: Diaphragm type liquid pressure control valve
Inventor: YAMAGUCHI KO
IPC: G05D16/06
Filed: 1989-02-08
Abstract: PURPOSE:To prevent the damage of a diaphragm for improvement of the durability and the reliability by forming a partition wall in a primary valve chamber in order to secure a prescribed damper chamber against the diaphragm. CONSTITUTION:A partition wall 11 serving as a valve body support guide part 13 is prepared in a primary valve chamber 1b, a small hole 12 is drilled through the wall 11, and a damper chamber is formed between the wall 11 and a pressure receiving diaphragm 4. In such a constitution, the primary pressure of the liquid supplied into the chamber 1b of a valve box 1 is applied to the diaphragm 4 via the chamber 10. At the same time, a valve rod 3a of a valve body 3 pivotally supported by the part 13 of the wall 11 and slided. Therefore the fluctuation of the primary pressure of the liquid, if increased suddenly and transiently, is absorbed by the chamber 10. Thus the excessive dynamic pressure is never applied to the diaphragm 4. In addition, the attenuation coefficient of a valve mechanism increases with application of the fluidal and mechanical damper functions. As a result, the induction of the automatic vibration is suppressed and furthermore the lateral movements are restricted. Then the guide mechanism of the body 3 is stabilized and the induction of the lateral vibration is also suppressed.
