Title: Rotary compressor
Inventor: IWATA HIROSHI
IPC: F04C18/356
Filed: 1984-04-25
Abstract: PURPOSE:To reduce friction loss provided between a roller and a crank of a rotary compressor by forming an escape on the face of the crank at the side opposite to that at which a maximum resultant force of the crank operates, therefore said face being subjected to low working load. CONSTITUTION:An escape 22A is formed on the face of the crank A of this rotary compressor at the side opposite to that at which a maximum resultant force of the crank operates, therefore said face being subjected to low working load. Oil is supplied in this escape from a branch hole 19 separated from the shaft hole 17 passing through a rotary shaft 5, thereby lubricating the opposing faces of the internal face of the roller 3 and the crank 4A. The face which is subjected to the resultant force of the crank is thereby maintained to be supplied with sufficient lubricating oil so that the friction loss between the roller 3 and the crank can be reduced.

Title: Corona discharge device of electrophotographic copying machine
Inventor: TSUCHIYA HIROAKI
IPC: G03G15/02
Filed: 1979-06-28
Abstract: PURPOSE: To make the charge distribution of photosensitive drum surface even by forming the end edge of a conductor plate opposing to a photosensitive drum in arc form which approaches to the photosensitive drum surface at the center and leaves from this at both ends.  
     CONSTITUTION: A photosensitive drum 1 is rotated in the direction of an arrow and the photosensitive drum 1 is charged by the corona discharge generated by a discharge member 2. The central part of the photosensitive drum 1 is better in charge efficiency and becomes higher in electric potential than its both ends. Thereupon, a conductor plate 4 is disposed in the position where the photosensitive drum surface passes after the charging by the cornoa discharge, nearly perpendicularly to said surface so as to cause reverse discharging of the charge on the photosensitive drum surface and the end edge 5 of the conductor plate opposing to said surface is formed in arc form which is close to the photosensitive drum surface at the center and leaves from said surface at both ends so that an even charge distribution may be obtained on the photosensitive drum surface. As a result of this, the charge on the photosensitive drum is reversely discharged to the conductor plate side along with the rotation of the photosensitive drum toward the arrow direction, whereby the evening of electric potential is obtained and beautiful copying is accomplished.

Title: Joint structure for scroll compressor
Inventor: INAGAKI MITSUO
IPC: F01C17/06
Filed: 1981-05-30
Abstract: PURPOSE:To enable it to lessen friction loss and carry out accurately an effective prevention against rotation, by providing spherical bodies at the position orthogonalized with each slit being configured in a fixed ring member and a movable scroll casing member respectively. CONSTITUTION:A spherical body 53 is set in a slit 51a configured in a fixed ring member 51 and a slit 2c of a movable scroll casing member 2 so configured as to be orthogonalized with said slit 51a each. With this condition, when the movable scroll casing member 2 rotates in an arrow direction, the slit 2a is dislocated from 2c shown in illustration with broken lines, and the spherical body 53 is consequently to be shifted to 53' due to slippage. Therefore, when the position of this spherical body 53 is kept up as it was, i.e., prior to rotation, the movable scroll casing member 2 is free from rotation.

Title: Manipulated variable recorder and camera
Inventor: OKAMOTO KEIICHI
IPC: H04N5/232
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent number of times of rewrites of a recording means from easily reaching number of limit times due to the service life or the like, even when the adjustment content is stored in a form of manipulated variable data obtained from an output of a variable resistor or the like by recording manipulated variable data to the recording means, when the operation of the operating knob is finished. SOLUTION: A control section 85 of a camera adaptor 8A discriminates whether or not any output from A/D converter circuits 87A-87D have changed. When the discrimination indicates an affirmative result, the control section 85 sets a value '10' to a count, having a function of a timer. In the case that any of operating knobs HP, HW, VP, VW is continuously operated for a continuous operating period, the control section 85 keeps the count of the counter to be the value 10. When the operation of the knobs is finished, the control section 85 gradually reduces the count and clears the count to be zero. Then coordinate data are updated, in response to the changed data, and a corresponding content of a memory 88 is rewritten by updated coordinate data.

Abstract: PURPOSE:To obtain a color-developing sheet having high color-developing capability and enhanced in light resistance of images, by incorporating a semisynthetic solid acid as a color developer and an amphoretic latex as a binder into a coated layer. CONSTITUTION:A color-developing sheet for an image-recording material is obtained by adding an amphoretic latex having an isoelectric point of pH 4.8-7.8 as a binder to an inorganic solid acid used as a color developer, then mixing a dispersant, a water-retaining agent and a defoaming agent therewith to prepare a coating liquid, applying the coating liquid to a base, and drying the applied coating liquid. If the isoelectric point is below pH 4.7, an effect on the light resistance of developed color images can not be obtained, whereas if the isoelectric point is above pH 7.9, the coating liquid is gelled. The pH of the coating liquid for forming a coated layer is preferably 8.3-11, and if the pH is not more than 8.2, the coating liquid is liable to be gelled, and a developed color density obtained is insufficient, whereas it the pH is not less than 11.1, an improving effect on the light resistance of developed color images is slight.

Filed: 1995-04-10
Abstract: PURPOSE: To obtain a method by which the final temp. of preheated coal can be precisely controlled and abrupt change in operation conditions can be coped with. CONSTITUTION: This method comprises rapidly heating powdery coal to 200 deg.C or higher but not higher than the maximum flow temp. of the coal with a high-temp. preheater by means of flash heating. The gas flow rate distribution, gas temp. distribution, inner-wall temp. distribution, and particle size of the coal are determined to obtain the quantity of heat (A) transferred by convection, i.e., the quantity of heat exchanged between the coal particles and the gas, and the quantity of heat (B) transferred by radiation, i.e., the quantity of heat exchanged between the coal particles and the inner wall. From the quantities of heat (A) and (B), the width of the final temps. of the coal particles is estimated.  The gas flow rate and the gas temp. at the inlet of the preheater are controlled based on the estimation to reduce the difference between a target final temp. of the coal and the actual one.
