Title: Method and device for polishing semiconductor substrate
Inventor: SUHARA TAKASHI
IPC: B24B7/22
Filed: 1992-04-20
Abstract: PURPOSE:To perform a polishing work with high flatness and to improve quality of a substrate by adding a fluid pressure directly to the given pressure region of a substrate holding member. CONSTITUTION:A pressure chamber 11 is partitioned by means of a seal member 10, a substrate holding member 4, and a fluid pressure member 8. When a fluid pressure is introduced in a pressure chamber 11 through a fluid introduction hole 9, a load exerted on the substrate holding member 4 is determined by a fluid pressure and a pressure area. Since a pressure is applied on the substrate holding member 4 at a constant value, a load exerted on the substrate holding member 4 is uniformized. This method regulates a processing pressure exerted on a substrate 1 through a balance between the seal member 10 and a fluid pressure. This constitution performs a polishing work with high flatness without being influenced by the shape before machining of the substrate 1 and size precision of the substrate holding member and a pressure mechanism.

Title: Method and circuit for contour painting out
Inventor: TONO YASUTAKA
IPC: G06T11/40
Filed: 1993-04-28
Abstract: PURPOSE:To shorten the time required for printing out a contour by taking an exclusive OR between the contour data and a buffer, writing in the buffer, taking the OR with the contour data and painting out. CONSTITUTION:In opposition to that the contour is scanned horizontally as usual, a high speed process is realized by parallel processing vertically at this case. This, the exclusive OR between the contour data from a bit map memory 1 and the data in the buffer 5 is taken to be written in the buffer 5. That is, the change point between the former result of the exclusive OR in the buffer 5 and this time result of the exclusive OR with the contour data is detected by the exclusive OR, and then, the OR between the result of the exclusive OR and this time result of exclusive OR with the contour data is taken, and the printing out dot data by process unit width are obtained. The exclusive OR between the data in a contour read buffer 2 and the data in the work buffer 5 is operated by an EXOR logical operation circuit 4. The OR between the data in the contour read buffer 2 and the data in the work buffer 5 is operated by an OR logical operation circuit 6.

Title: Optical scanner
Inventor: NAKAYAMA YOSHINOBU
IPC: H04N1/23
Filed: 1986-05-30
Abstract: PURPOSE:To secure uniform dot spacings without using an ftheta lens by changing the pulse modulaion frequency of a laser light source. CONSTITUTION:The picture signal is inputted to a laser diode control/drive circuit 7 via a picture signal processing circuit 1. The circuit 7 uses the picture signal to modulate the clock pulse delivered from a clock pulse generating part and then uses this modulated signal to give the pulse modulation to a laser diode 3. The diode 3 produces an impulsive laser beam which is turned on and off by the modulated signal. This laser beam is deflected by a polygon mirror 4 revolving at a constant speed and performs scan on a photosensitive body 6 toward an arrow to write pictures. Here no ftheta lens is used and the circuit 7 contains a correction means which changes the pulse modulation frequency of the diode 3 so as to secure the even dot spaces.

Title: Signal strength display device
Inventor: NAGASAWA TAKAFUMI
IPC: H03G1/00
Filed: 1984-06-18
Abstract: PURPOSE:To obtain the display where it is easy to grasp frequency characteristics, by releasing holding of peak values if peak values of all bands are not updated at all for a prescribed period determined by a timer circuit. CONSTITUTION:A memory 4a of a band f1 is selected by a selector 5, and the signal strength of the band f1 and its peak value are displayed on a matrix display device 9. If the peak value in another band is updated though the peak value in a certain band is not updated at all for the prescribed period determined by a timer circuit 13, the peak value is held. If the peak value is not updated in all bands at all for the prescribed period, holding of the peak value is released. Peak values of al bands are held for said prescribed period or longer just before holding of the peak value is released, and peak values of all bands are read at sight, and thus, the frequency characteristic is grasped easily.

Title: Clearance correcting device
Inventor: OHARA SHUNICHI
IPC: B65H5/06
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To certainly correct clearances among paper sheets on the way of carrying without being influenced by the thickness of the paper sheets, by arranging in a carrying pass, the rotational centers of one of a correcting roller pair supported by an arm and one of a thickness detecting roller pair so that one is arranged upward in the direction of the thickness of the paper sheets and the other is arranged downward therein. SOLUTION: On a locus on which paper sheets are carried, a driven roller 3 and a pulley 34 are arranged on a vertically opposite side across a rotating fulcrum 7. When the paper sheets are entered between a pulley 31 and the pulley 34, the pulley 34 is pushed up, an arm 35 is rotated, and a driven roller 4 is pushed up. When the paper sheets are rushed into between the pulley 31 and the pulley 34, the paper sheets are held and carried by a carrying belt 2, therefore there is enough carrying force and there is no carrying dispersion. If distance L1 from a correcting roller pair 15 to the paper sheets holding point 26 of a thickness detecting roller pair 41 is set less than the length of the paper sheets, at a point of time when reaching the correcting roller pair 15, a clearance between the driven roller 4 and driven roller 3 is widened, therefore resistance can be eliminated when the paper sheets are rushed into and carrying dispersion can be reduced.

Abstract: PURPOSE:To provide a sliding contact point material which uses the oxide generated as a lubricant and improves wear resistance by adding a specific amt. of Nb, In, Ba, Cd, etc. without changing the compsn. ratio thereof to an alloy material having a specific compsn. consisting of Pd and Ag. CONSTITUTION:A sliding contact point material is formed by adding 1-10% at least one kind among Nb, In, Ba and Cd without changing the compsn. ratio thereof to an alloy material consisting of 30-70wt% Pd and 30-70% Ag or substituting a part of Nb, In, Ba and Cd with a ferrous metal in a 0.01-0.5% range according to need. Said material improves wear resistance by using the generated oxide as a lubricant and prevents generation of noise by suppressing generation of abrasive powder during sliding. The ferrous metal added in an adequate amt. to said material contributes to the formation of finer crystal grains hence to an additional improvement of the wear resistance.

Abstract: PURPOSE:To improve the communication efficiency by storing temporarily the one-original information capacity or larger of picture data outputted from a decoding circuit and converting picture data outputted from a storage circuit in vertical and horizontal directions to output this data to a recording circuit. CONSTITUTION:When the plural originals of A5 size are transmitted continuously from an equipment 1 to an equipment 2, the equipment 2 receives code data from the equipment, which encodes successively picture data in the direction of an arrow A of originals of A5 size and transmits them onto a line, and decodes them by a decoding circuit 14 and stores temporarily picture data in a picture data storage circuit 13 in accordance with the storage address in the direction of the arrow A. After one-page components of picture data are stored completely, a vertical/horizontal converting circuit 12 is used to read out successively picture data stored in the circuit 13 in accordance with the storage address in the direction of an arrow B and supplies them to a recording circuit 11 to obtain the recorded picture of A5 size. Thus, a half of a original of A4 size is received equivalently for reception of the original of A5 size, and the communication efficiency is improved.
