Title: Centering device of disk
Inventor: SAEKI TAKAHARU
IPC: H01L21/02
Filed: 1990-07-10
Abstract: PURPOSE:To certainly center two types or more of wafers whose radii are different by forming two or more of circular arc sections whose radius curvatures are different on a curved surface of centering guides. CONSTITUTION:A small circular arc section C2 in the radius of curvature is formed inside the curved surface G of a centering guides B1 and B2, and large circular arc section C1 in the radius of curvature are formed on both outer sides of the circular arc C2. Therefore, the outside circular arc sections C1 are brought into close contact with the outer peripheral surface of a large wafer A1 in a radius (r1) at 4 places, and the inside circular arc sections C2 are brought into close contact with the outer peripheral surface of a small wafer A2 in a radius (r2). In addition, even if the original flat section 0 of the wafer A1 abuts on one of the outside circular sections C1, the 3 re3st circular sections C1 are brought into close contact with the outer peripheral surface of the wafer A1. Therefore, the wafer A1 is certainly centered and, moreover, stably supported.

Title: Character recognizer
Inventor: KOMIYA MASAKI
IPC: G06K9/36
Filed: 1984-08-31
Abstract: PURPOSE:To separate assuredly rows and characters with the simple control despite the shift of a print position, by correcting the center positions of virtual rows at and after the 2nd row according to the difference between the center position of characters on the 1st row and that of a virtual row. CONSTITUTION:A reading pattern having the width L measured from the upper end of a form is stored to a line buffer 40, and a projected image is obtained by a projection means 51 in the row direction of the buffer 40. The center position of a row is detected from the projected image through a row center position detecting means 52. An arithmetic means 53 obtains a difference alphabetween said row center position and the center position of the 1st row of a virtual row center position buffer 54. A correction means 55 corrects the virtual center positions of the 2nd and subsequent rows. If the virtual center position of the n-th row is defined as An, the virtual center position of the n-th row is corrected to (An+alpha) in consideration of the difference alpha. For the 2nd and subsequent lines, both visual point and field of the buffer 40 are decided based on the value of the corrected buffer 54. Then the rows are separated.

Title: Transmission type screen
Inventor: MURAO TSUGIO
IPC: G03B21/62
Filed: 1986-08-01
Abstract: PURPOSE:To improve the contrast of an image even if the titled screen is observed in a light room, by constituting it so that an incident angle to the second surface of alight beam which is made incident and emitted vertically to and from a mirror becomes smaller than the critical angle of a total reflection, a light absorbing means is arranged at a prescribed interval on the emitting side face, and a projected luminous flux passes through the light absorbing means. CONSTITUTION:A projected luminous flux made incident on the incident side face of a transmission type screen transmits refractively through the first surface 14 of a prism element and brought to a total reflection by a second surface 15, transmits refractively through the part of the third surface 16 of an emitting side face, and thereafter, emitted almost vertically to the screen. Accordingly, a V-shaped groove 18 and a light absorbing layer 19 exert no influence at all on the projecting luminous flux required for forming an image. In such case, the screen consists of such a structure as an incident angle to the second surface 15 of the prism element of a light beam which is made incident and emitted vertically to and from a mirror 3 becomes smaller than the critical angle of a total reflection, therefore, with respect to all light beams that are reflected by the mirror 3 and returned to the screen, the incident angle to the second surface 15 of the prism element becomes smaller than the critical angle of the total reflection, when the light beam is made incident on the screen, or when it is reflected by the mirror 3 and made incident again on the screen.

Title: Advanced treatment of sewage
Inventor: SHIBAYAMA DAIGORO
IPC: C02F3/06
Filed: 1990-07-10
Abstract: PURPOSE:To deposit suspended solids and fine org. matter in sewage on the biological membrane of a contact material by their dead weight and to oxidize and degrade them by carrying out intermittent aeration in a contact aeration tank. CONSTITUTION:When aeration is suspended and a flow of sewage is stopped, org. matter and suspended solids in the sewage deposit on the biological membrane of a contact material by their dead weight. When aeration is started again, aerobic microorganisms are supplied with much oxygen and act violently. Since the org. matter and other nutrient are present in plenty on the biological membrane, the sewage can be very efficiently and completely treated.

Title: Surface treatment of wire rod
Inventor: TOKI YOJI
IPC: C23F1/00
Filed: 1986-08-04
Abstract: PURPOSE:To obtain a wire rod having uniform surface roughness in a range over all length without causing abnormality of surface unevenness by reperforming surface roughening treatment by means of heat-treatment and pickling for a remaining coil wherein the abnormality of surface unevenness is caused in the surface texture roughening treating stage of the wire rod after peeling or cutting. CONSTITUTION:After peeling or cutting a wire rod prior to a wire-drawing processing similarly heretofore in order to remove a surface flaw, it is heat- treated to cause scale on the surface and the scale is removed by pickling to perform surface roughening. A second-time surface texture roughnening treatment is successively performed for the wire rod caused with the abnormality of surface roughening by the above-mentioned surface roughening treatment. In other words, after the above-mentioned surface roughening treatment, the heat-treatment and pickling treatment are immediately performed. Thereby the abnormal surface part caused in a first-time surface roughening treatment is eliminated and the wire rod having required uniform surface roughness in a range over the full length is obtained.

Patent JP-S6428739-A (JP)
Title: Parity circuit
Inventor: SHIBUKAWA MASARU
IPC: G06F11/10
Filed: 1987-07-24
Abstract: PURPOSE:To eliminate need for increase in the circuit constitution and parity generation and detection time by generating or detecting the parity by an FF and outputting the result in a prescribed timing. CONSTITUTION:A shift register 2 fetches the content of a register 1 when a shift clock phi goes to L and a control signal P/S goes to H. Every time a serial data bit of level 1 appears at an output terminal of the register 2, the output Q level of the FF 4 is inverted and the parity is generated while taking exclusive OR sequentially according to the output of the register 2. Thus, when the prescribed bit data is outputted serially from the register 2, the storage state of the FF 4 attained by a preceding output data bit is subjected to inverting control or stored in response to the sign and the state of the FF 4 is confirmed by the output of the final bit data. Thus, the parity is generated or detected.
