Title: New/old discriminating device about parts for image forming device
Inventor: SUZUKI TOMOFUMI
IPC: G03G21/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To enable anyone to exchange parts used and to surely maintain the parts used by detecting the conductive state of a conductive state changing element and deciding that parts are new or old by a change in the output signal of the detection. SOLUTION: A use history presence detecting device 11 is in the conductive state, when a fixing device is not used. When a new fixing device 1 is incorporated in an image forming device and its power is supplied, the temp. of the heating roller of the fixing device rises by a heat source. Therefore, the use history presence detecting device 11 is changed into a nonconductive state by the rising of the temp. The conductive state of the detecting device 11 accompanying the rising of the temp. is detected by a control part 10 and a control circuit fixing device coefficient means provided on the main body side of the image forming device is reset with the output signal from the control part 10. After that, the fixing device coefficient means counts the number of sheets used by the image forming device or its energizing time.

Title: Semiconductor memory
Inventor: HIDA YOICHI
IPC: G11C7/06
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To perform a high-speed sensing operation under low power voltage by amplifying differentially voltage of a pair of bit line to which a memory cell arranged in line is connected conforming to voltage on a sense drive line, and holding a prescribed voltage after a sense drive line is overdriven for a prescribed time exceeding the prescribed voltage responding to the activation of a sense operation instruction signal. SOLUTION: Bit lines BL, /BL and sense drive lines SALa, SALb are pre- charged to a power source voltage VCC level. In sense drive control circuit 4, a driver 14 receives boosted voltage VBST instead of power source voltage VCC. A node ND2 and the sense drive line SALb are varied between VCC- VBST (>=-VCC/2). Maximum voltage of 3VCC/2 is applied between a drain and a source of transistors NT1, NT2 constituting a N sense amplifier of a sense amplifier SA, the high-speed sensing operation can be performed even under low power voltage.

Title: Leakage breaker
Inventor: HONDA KAZUYOSHI
IPC: H02H3/32
Filed: 1978-03-31
Abstract: PURPOSE: To permit direct measurement of the insulation resistance of the line for supplying power  to a load by connecting a capacitor having a far high impedance compared to the impedance of the trip coil to one terminal of a power source.  
     CONSTITUTION: A capacitor C 0  having a far high impedance compared to the impedance of a trip coil T c  is connected to one end of a power source, and a current-limiting resistor R 0  is connected to the other end of the power source. The other ends of the capacitor and resistor constitute respective detector power source terminals a and b, between which a non-linear resistor element A such as a varistor to provide a constant voltage between them, and a smoothing and rectifying circuit 1 is connected between these terminals. With this construction, the source voltag for the load is rendered into a constant voltage through the capacitor before it is applied to a leakage detection circuit. Thus, even if the power source for the load and the load are interchanged with respect to the power supply line to the load, only slight current flows through the leakage detection circuit at the time of occurrence of leakage, so that it is possible to prevent burning of the trip coil. In addition, since the leakage detection circuit can be perfectly cut off from the power supply line with the DC component of the insulation resistance measuring instrument cut off by the capacitor, it is possible to obtain measurement of insulation of a semiconductor part without causing rupture thereof.

Title: Expanding pin
Inventor: ARUMIN HERUPU
IPC: F16B13/10
Filed: 1986-02-25
Abstract: An expansion dowel includes an axially extending expansion sleeve and an expansion member rolled from a section of sheet metal. The sleeve has a leading end and a trailing end and the inside surface of the sleeve is threaded for an axially extending section from the trailing end. The thread is formed before the sheet metal is rolled. To assure there is no misalignment of the thread along the butt joint, tangs and recesses are formed along the edges of the butt joint so that the edges interengage one another when the sheet metal section is rolled. By interengaging the butt joint edges, the sleeve does not expand circumferentially when a bolt is threaded into the trailing end of the sleeve.

IPC: B01D53/68
Filed: 1988-02-22
Abstract: PURPOSE:To remove hydrogen chloride gas properly without generating excess or shortage in the amount of using of alkaline agent, by a method wherein the supply of alkaline agent into a secondary combustion furnace is started when a temperature in a primary combustion furnace has arrived at a certain value while the supplying amount of the alkaline agent is controlled so as to be maximum in an initial period, and thereafter, it is reduced in accordance with the elapse of time. CONSTITUTION:When a temperature in a primary combustion furnace 1 has exceeded about 150 deg.C after starting combustion, the thermal decomposition of rubber is advanced quickly and the concentration of hydrogen chloride gas becomes maximum at the temperature of about 400 deg.C, thereafter, it is reduced gradually in accordance with the elapse of time. When 1,600kg of waste of rubber, whose chloride content is 10%, for example, is incinerated, the supplying amount of alkaline agent into a secondary combustion chamber 2 becomes the amount of slaked lime of 167kg. When a reaction rate is considered therein, the necessary amount of the slaked lime becomes about 250kg. Accordingly, the supply of the slaked lime is started when the temperature has arrived at about 150 deg.C and the maximum supplying amount of 160kg per 1hr is supplied for initial 30min while the supplying amount is reduced stepwise in accordance with the elapse of operating time and the total supplying amount of it is set to be 250kg.

Title: Production of granular body of low melting alloy
Inventor: MITSUI TOMOKUNI
IPC: B23K35/40
Filed: 1991-02-08
Abstract: PURPOSE:To prevent the occurrence of contact and bonding among mutual granular bodies due to lateral movement by regulating the clearance between plural nozzle holes provided to a nozzle so that it is longer than the bore diameter of the nozzle hole. CONSTITUTION:A clearance (c) between mutual plural nozzle holes 51 at the end of a nozzle provided to the inside of a heating zone is regulated so that it is >=3 times the bore diameter (d) of the nozzle hole. A crushed low melting alloy is put into the nozzle, and the liquid temp. in the heating zone is elevated to melt the low melting temp alloy. The inside of the nozzle is pressurized by gas pressure, and vibrations are applied to the nozzle by means of a vibrator. The molten metal in the nozzle is extruded via the nozzle holes 51 and is cut and broken by means of the force of vibration. Because the molten state of the cut granular bodies is maintained in the course of falling down in the heating zone, spheroidizing can be allowed to proceed during falling by means of the surface energy of the molten metal itself and the interface energy between the molten metal and the heated liquid. The solidification of the spherical granular bodies is completed in a cooling zone.
