Title: Polishing method for wafer
Inventor: NAKAMURA MIKIO
IPC: B24B37/10
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress excessive polishing only to a specific portion of a wafer by reversing the rotating direction of the wafer between polishing in a first step and polishing in a second step. SOLUTION: A wafer is positioned under a polishing head 4 of a primary polishing device 10a and the polishing head 4 descends, thereby executing primary polishing of the wafer. After finishing the primary polishing, the polishing head 4 rises and a plate 6 is conveyed onto a surface plate 11b of a primary polishing device 10b. At this time, the polishing head 4 of the primary polishing device 10b descends, thereby executing the primary polishing of the wafer again. The rotating direction of the surface plate 11b is reverse to the rotating direction of the surface plate 11a. Therefore, the flowing direction of slurry is reverse to the wafer. According to this method, excessive polishing only to a specific portion of the wafer is suppressed, the wafer with high flatness is obtained, and the operating performance is also remarkably improved.

Title: Signal generating circuit
Inventor: KOYAMA TAKAHIRO
IPC: H03K4/83
Filed: 1983-05-19
Abstract: PURPOSE:To realize high-speed operation and to obtain a stable saw-tooth pulse wave which operates even with a small control signal small in rising and falling capacities by adding a latch-up circuit to a transistor (TR) for pulse triggering. CONSTITUTION:This circuit uses two TRs which differ in polarity as switches. When a rising bias is applied to the 1st control terminal 1-1, a differential signal is supplied by a capacitor 52 and a resistance 53 to turn on an NPN TR50. Consequently, a current is supplied to a resistance 41 to cause a voltage drop, and a PNP TR40 supplies a current to a resistance 51, so a feedback loop is formed. Namely, a switch circuit enters a latch-up state and a capacitor 10 charged by a current source 200 is discharged, so that the output voltage at an output terminal 3 drops abruptly. When the discharging of the capacitor 100 is completed, the latch-up state held by the NPN TR50, PNP TR40, and resistances 41 and 51 is reset and a saw-tooh wave signal is generated.

Title: Heat insulating mat material for vehicle trunk room
Inventor: MORITA TOSHIO
IPC: B60N3/04
Filed: 1989-04-07
Abstract: PURPOSE:To provide good fitting of a mat to the roughness of a floor surface even in its state of only being laid thereon, ensure stable strength and prevent dust from staying on its surface by using an adjacent warps braided net with various sizes of mesh an interlining cloth and covering braided yarn with foaming resin without causing large meshes to be filled up and forming foaming projections in filled small meshes. CONSTITUTION:To a warps braided net used as interlining cloth, a foaming resin composite is sprayed or a roll coater or the like is applied for foam generation. It is hard for a foaming resin composite to stay in large mesh clearances 11, so that they usually remain as clearances and it is easy for it to stay in small mesh clearances 12. Therefore, a lot of foaming resin composites is deposited so as to fill up the clearances 12 and form foaming projections 14 which are raised largely by foaming. As a result, the large clearance 11 form openings 16, whose peripheries are surrounded by foaming projections 14 to generate the most suitable vehicle trunk room heat insulating mat material 15. Accordingly it is better to use a warps braided net which has large different sizes between clearances 11 for forming the openings 16 and sizes of the clearances 12 for forming the foaming projections 14, and viscosity of foaming resin composites is adjusted according to the difference in the size of the clearances.

Abstract: PURPOSE:To obtain high resolution images even in low image signal voltage, by keeping the voltage to be applied to a shield electrode at a proper value below about 40% of the image signal voltage and same in polarity as this. CONSTITUTION:A plurality of stylus electrodes 13 are covered with insulator 14 and buried in shield electrode 12 to form recording electrode 11. Recording material S like a band or the like is located between electrode 11 and donor member 7 holding ink particles 8 in a layer on the surface by magnetic force.
