Title: Grinding method for uniaxial eccentric rotor
Inventor: TSUJI HIROYUKI
IPC: B24B19/14
Filed: 1986-10-17
Abstract: PURPOSE:To make a workpiece accurately grindable, by precalculating a position of a ceramic round grinding approachable from the normal direction of a uniaxial eccentric rotor, and grinding the workpiece successively while moving the grinding wheel according to this position. CONSTITUTION:When a point B on a Z1 section of a uniaxial eccentric rotor is ground, if a tip section center G on a round tip of a grinding wheel 2 is left place on the Z1 section intact, there might be a fear that a blank has been excessively ground. Accordingly, a straight line E, passing through the grinding point B and coming into contact with an external surface, is defined finding such a point G1 that causes a distance from the grinding point B become a sectional radius (r) at the tip 3 of the grinding wheel 2 on a straight line F vertical to this line #, whereby section grinding is carried out while moving the grinding wheel 2 in a Z-axis direction and both X-and- Y-axis directions so as to cause the center G of the tip section center G1 to accord with the point G1. Likewise afterward, a grinding radius of the grinding wheel 2 is set to R, and accuracy of finishing to (h), respectively, whereby a section Z2 and the grinding wheel 2 are successively moved according to a calculated value at each pitch P to be found out of h=P<2>/8. Thus accurate grinding is performable.

Title: Vertical field-effect transistor
Inventor: FUJIMOTO SHINJI
IPC: H01L29/78
Filed: 1989-09-26
Abstract: PURPOSE:To shorten a reverse recovery time by a method wherein a second layer of an N-conductivity type is exposed on one main surface of a substrate of the N-conductivity type and is brought into contact with a source electrode so as to pass the central part of a region of a P-conductivity type and a Schottky barrier diode region is formed in this part. CONSTITUTION:A second layer 12 of an N-conductivity type is exposed on one main surface of a substrate 11 of the N-conductivity type and is brought into contact with a source electrode 18 so as to pass the central part of a region 13 of a P-conductivity type as a self-isolation region, a Schottky barrier diode region 21 is formed. As a result, in this structure the Schottky barrier diode 21 is connected in parallel between a drain electrode 19 and the source electrode 18 while a flywheel diode is left. Consequently, when an area and a shape of the Schottky barrier diode 21 are selected properly in a relationship with the flywheel diode, a forward rise voltage of the flywheel diode can be made higher than a forward rise voltage of the Schottky barrier diode 21. Thereby, a diode current flows preferentially in the Schottky barrier diode, and a reverse recovery time of a built-in diode can be shortened.

Title: Method for calculating dot gain and method for correcting dot
Inventor: KISHIDA YOSHIHIRO
IPC: B41F31/02
Filed: 1990-09-18
Abstract: PURPOSE:To precisely calculate a dot gain by calculating the dot gain on the basis of a thickening width measured in advance and applying the result of this calculation to the correction of a dot to find out an increase in a percent dot area. CONSTITUTION:A test chart TC including a predetermined line width is printed (P0), a thickening width 'q' on one side of the printed line is measured (P2) in advance, the enlarged area 'd' of each dot DT in a reference region CR which specifies a 100 percent dot is computed (P3) when each dot DT before printing is enlarged by the thickening width 'q' throughout the peripheral length, and a dot gain f(k) is calculated from said enlarged area 'd'. For example, when printing is performed by using a dot that is a square dot in a shape, the dot DT is thickened with the thickening width 'q' throughout the entire periphery of the dot DT, and the dot area is increased. An increase in the dot area can be calculated from the entire peripheral length of the dot DT and the thickening width 'q'. Further, the thickening width 'q' which occurs during a printing process can be easily and correctly measured by printing a test chart including a fine line and measuring the line width of the printed fine line with a microscope and the like.

Title: Composite carrier for electrophotographic developer
Inventor: NAKAMURA NAOMICHI
IPC: G03G9/10
Filed: 1987-10-05
Abstract: PURPOSE:To enable both of high image density and low fog density to be attained by mixing 2 kinds of carriers different in toner electrifying performance from each other, that is, the one higher in said performance and the other lower in that. CONSTITUTION:In 2 kinds of the carriers to be mixed, the carrier L lower in the toner electrifying performance mainly plays the role of attaching the toner to the part of a latent image, and the carrier H higher in said performance mainly plays the role of removing the toner remaining on the nonimage part. The carrier allows the toner to have a charge quantity of 5-25muC/g, and if it is below 5muC/g, scattering of the toner becomes a problem, and if above 25muC/g, attachment of the toner to the image part becomes insufficient. The carrier H allows the toner to have a charge quantity of >=30muC/g, and if it is below said limit, sufficient toner removing ability cannot be obtained. The mixing ratio by weight of both carriers L/H is 95:5-50:50, preferably, 90:10-75:25, thus permitting the balance of the roles of these 2 kinds of carriers to be correctly controlled and an image high in density and low in fog to be obtained.
