Title: Oil coating device for copying device
Inventor: OWADA AKINOBU
IPC: G03G15/20
Filed: 1988-03-09
Abstract: PURPOSE:To reduce the friction against recording paper and to prevent toner from being separated by providing the oil coating device to the heat roller of a fixing device which fixes an unfixed transfer image and applying a specific amount of oil at the time of fixation. CONSTITUTION:A pressure roller 2 rotates as a heat roller 1 rotates. An oil coating roller 8 which is pressed against the roller 1 is rotated by the friction of the roller 1. Then the silicone oil is applied onto the peripheral surface of the roller 1 while being supplied from the oil-impregnated pad 113 of an oil supply means 11. Consequently, the oil is applied thinly and uniformly onto the surface of a toner image which is melted with the heat of the roller 1 and fixed on the recording paper. Consequently, even when the recording paper where the toner image is fixed is stacked and used as a 2nd document, the friction coefficient decreases and the toner is prevented from being separated by rubbing.

Abstract: PURPOSE: To form an anode oxide film having high heat conduction, electric insulation capability and heat resistance, by generating a crack on the anode oxide film formed on the surface of a metal, and impregnating and polomerizing a polymerizing organic metal compound in a fine hole and the crack.  
     CONSTITUTION: On a metal such as an Al material, etc., an anode oxide film is formed, is heated to about 300W400°C, and a crack is generated on the film. The anode oxidation treatment is performed to said film once again as necessary. The film on which this crack has been generated is soaked in a solution containing a polymerizing organic metal compound such as phenyltriethoxysilan, etc., the compound is impregnated and polymerized in a fine hole and the crack on the film, and is dried thereafter. In this way, the fine hole and the crack are airtightly filled up with an organic metallic compound polymer, and a high electric insulating property is obtained. Also, since the polymer is a metallic compound, a high heat conduction of the anode oxide film is maintained.

Abstract: PURPOSE:To permit easy removal of the jammed paper in a fixing unit by disposing an elastic member which energizes the upper half of the fixing unit to an inclined open angle position at all times. CONSTITUTION:The operator opens the upper half 1A of a copying machine 1 body when paper is jammed in said machine. The upper half 10 of a fixing unit 8 is then released from the restraint by a compression coil spring 7 and is titled and opened to a small inclined open angle theta by the effect of a coil spring 13.

Title: Highly precise measuring system for water level in reactor
Inventor: YANAI KATSUYA
IPC: G01F23/14
Filed: 1980-05-02
Abstract: PURPOSE:To improve safety of a reactor at a normal and an emergency time, by a method wherein various error factors, which result from a differential pressure system measurement of a water level in a reactor, are analyzed. CONSTITUTION:A reference level gauge 2 and temperature measuring bodies, which are positioned at equal spaces perpendicularly on the outer circumference of a measuring pipe located below said gauge, are installed. For example, 4 points are measured in the vertical direction to obtain measured temperatures tL1-tL4. A mean temperature in the vertical direction of water in a reference surface from the 4 points is obtained through the correction made based on an influence coefficient against the whole at each point where an actual measurement is conducted. A mean specific amount of water in the reference level gauge 2 is then calculated using a steam table from the pressure and mean temperature in the vertical direction in the reactor. A water level is determined based on the mean specific gravity amount, a specific gravity amount of a steam phase, a specific gravity amount of a reactor water, a velocity of flow in a reactor water measuring tap position and an output of a differential pressure detector 4.

Title: Liquid sensor for tube
Inventor: UENO KUNIO
IPC: G01F23/28
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To clearly detect the presence or absence of a liquid in a tube even when the tube has a fine size with respect to the sizes of a light emitting element and a light receiving element, by installing proper slit members at the front and rear of the tube. SOLUTION: A translucent tube 3 is arranged in the optical path from a light emitting element 1 to a light receiving element 2. When a liquid exists in the tube 3, the tube 3 acts as a convex lens because the tube 3 and liquid have a nearly equal refraction factor, and the light from the light emitting element 1 is relatively simply refracted to reach the light receiving element 2. When no liquid exists in the tube 3, the light passing through the hollow section of the tube 3 and the other light are mutually much differently refracted, and the light from the element 1 reaches the element 2 after being complicately refracted. A slit member 4 is provided between the element 1 and tube 3, and a slit member 5 is provided between the tube 3 and element 2.  The slit member 5 shields the light passing through the tube 3 from the element 2 when the liquid exists in the tube 3, and it allows the light to pass to the element 2 when no liquid exists in the tube 3, and the presence or absence of the liquid can be detected.

Abstract: PURPOSE:To judge the maintenance timing of an insulator properly by dropping droplets on the surface of the insulator, measuring the contact angle of the droplets, and assuming leak current of the insulator surface from the value at the time of raining. CONSTITUTION:A cylinder 31 which is the measuring surface of an insulator 3 is adjusted to be horizontal, and a contact angle measuring device 4 is installed on the cylinder 31. A piston 44 is operated to drop minute droplets from a needle 46 to the cylinder 31, the droplets 2 are lit by a light source 43, and the image of the droplet 2 is expanded by a lens 41 to be projected on a screen 42. A rotational plate with a gauge which is formed at the screen 42 is rotated to read out the contact angle theta of the droplets 2 to the surface of the insulator 3. By monitoring the contact angle theta which has been read out, it is possible to assume leak current on the surface of the insulator 3 at the time of raining, and judge the maintenance timing of the insulator 3 properly.

Title: Servo access system
Inventor: IWAI TAKEO
IPC: G11B21/08
Filed: 1982-04-09
Abstract: PURPOSE:To eliminate unnecessary increase in seeking time during large track seeking and to shorten the mean access time of a magnetic disk device, by determining to the optimum a servo access system with a means which does not fixes a target speed curve according to the extent of seeking in every seeking operation to reset the target speed curve for the magnetic disk device. CONSTITUTION:In a figure, an x-x' curve generator 2 generates a target speed corresponding to the remaining number of tracks supplied from a remaining track counter 2 according to the target speed curve set by a target speed curve selector 3. The difference between a current target speed and the actual speed of a head carriage 6 detected by a speed detector 7 is detected by a speed error detector 4. A voice coil motor as a driving source for the head carriage 6 is driven by a power amplifier 5 so that the speed error is compensated. Thus, the head carriage 6 and a head mounted thereupon move at a speed following up the target speed curve set by the selector 3 to seek a desired track position.
