Title: Electron-beam exposure method
Inventor: KOMATSU BUNROU
IPC: G03F7/20
Filed: 1982-06-30
Abstract: PURPOSE:To reduce a proximity effect through simple operation, and to obtain a pattern of a fine shape with high accuracy by drawing electron beams in the quantity of a dose lower than the aimed quantity of a dose on a resist film in a repeated manner when electron beams are drawn on the resist film and the film is exposed. CONSTITUTION:Polymethyl methacrylate is rotary-applied onto a blank mask or a wafer, and baked to form the positive type resist film. Electron beams are irradiated to the film and drawn, but they are drawn first in the half quantity of a dose of the aimed quantity of a dose at that time. Electron beams are irradiated to the same section in the half quantity of a dose again, and the section is developed and treated to form the resist pattern. Accordingly, a section subject to the proximity effect is difficult to be developed, and the pattern is fined. Electron beams may be drawn twice while halving irradiation time in place of twice irradiation while halving the quantity of a dose.

Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To effectively use a battery in a receiver for an FM teletext broadcasting. SOLUTION: A tuner 11 receives FM taletext broadcasting. Telext broadcasting data is extracted and is supplied to a decoder 14. Data is decoded in the decoder 14 and an error is detected by a CRC(cyclic redundancy check) code for every packet. Valid packets are counted based on an error detection flag. When more than prescribed packets are obtained in the counting period of two seconds, a switching element 21 is turned on based on the control of CPU 15 for next five seconds. Power 30 is supplied to the decoder 14. When the number of packets obtained in two seconds of counting does not reach the prescribed one, the switching element 21 is turned off for next five seconds and the supply of the power of the decoder 14 is stopped. Thus, sequence for seven seconds is repeated.

Title: Manufacture of semiconductor device
Inventor: ICHIMURA HIROSHI
IPC: H01L21/331
Filed: 1988-05-10
Abstract: PURPOSE:To obtain a semiconductor device which has an N-type diffusion region in which rosettes are few and sheet resistance is sufficiently low by forming a glass layer which does not contain at all or contains antimony on an antimony glass layer so as to apply heat treatment. CONSTITUTION:A glass layer 4 which does not contain at all or contains antimony is formed on an antimony glass layer 3 and heat treatment is applied to it. In the case of glass layer which does not contain antimony at all, antimony compound, Sb2O3 or Sb2O5 comes to be unable to sublime from the surface of the glass layer even in the thermal diffusion temperature, and sufficient diffusion can be performed for a semiconductor substrate. In the case of glass which contains antimony, not only prevention of sublimation, but in the case that Sb atom concentration inside the antimony glass layer has decreased, Sb atoms are supplied and Sb atom concentration at a semiconductor substrate interface comes to be maintained almost constant, and extremely efficient diffusion can be executed. Hereby, low sheet resistance can be obtained and generation of rosettes is suppressed.

Title: Image forming apparatus and communication method for image data
Inventor: IZEKI YUKIMASA
IPC: B41J2/44
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To raise a speed of image forming without raising a speed of a clock by a method wherein a communication means transmits data of a plurality of pixels in an interval time of one clock of a second clock which is provided independent from a first clock and is corresponding to an image forming clock. SOLUTION: Image data is outputted by two pixels in parallel by a low speed clock PCLK 2 as VD [7:0] and is converted to image data VDP [7:0] which is in synchronism with a high speed clock PCLK by a parallel data converting section 103 which is a front stage of a laser driving circuit 104. One pixel is divided into plural blocks to be recorded by using an inner delaying function of the laser driving circuit 104, thereby preventing heat or radiation noise from being generated. A VDR [7:0] outputted from an image processing section 101 is inputted to an image processing speed controlling section 102 in synchronism with a basic clock in the image processing section 101, e.g. an RCLK of 20 MHz, then the synchronization of the basic clock with an image forming basic clock is accomplished.

Title: Pneumatic tire
Inventor: KATAYAMA MASAHIRO
IPC: B60C11/11
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To improve wet grip performance, brake on the ice, driving performance and uneven wear resisting performance by restraining a pneumatic tire from having its grounding property deterioration when the number of sipes are increased. SOLUTION: A block-shaped land part 18 is formed with a plurality of sipes 20 zigzag extending along the tire in the cross direction. The sipes 20 being formed with slants 20C on the intermediate portions in the depth direction have larger contact area on the sipe walls than the sipes extending straight in the depth direction so that the sipe walls facing each other easily come into contact just by the block-shaped land part 18 receiving compressional deformation. For this reason, sipe contacting force comes still more stronger when the block deforms and the block-shaped land part 18 can be restrained from collapsing more effectively than the conventional ones at the time of braking drive when the number of sipes are increased, which serve to improve wet grip performance, on-the-ice-braking and uneven wear resisting performance.

Abstract: PURPOSE:To eliminate the need for a lead wire and to prevent an oscillation frequency from going to unstable by running the input/output terminal of an oscillation circuit loosely through the insertion hole of a metallic base and leading it out to a substrate side where the reverse surface of the metallic base is fixed, and thus making an external connection. CONSTITUTION:A screw part 9a is cut threadably in the outer circumferential edge of the discoid metallic base 9. A printed board 10 which mounts the oscillation circuit 11 on the top surface is fitted while its reverse surface is in contact with the recessed surface on the top surface of the metallic base 9. The input/output terminal 14 inserted into the through hole of the input/output pattern of the printed board 10 is longer than the thickness of the metallic base 9 and projects from the reverse surface of the printed board 10, running through the insertion hole 18 of the metallic base 9 at a sufficient interval from the internal wall. While a metallic cover 12 is engaged with the metallic base 9 threadably, an O ring 16 is pressed against the top surface of the circumferential edge of the metallic base 9 to enclose the oscillation circuit 11 including the pirnted board 10. This constitution includes no lead wire in rocking motion, so the oscillation frequency never goes to unstable.

Abstract: PURPOSE:To prevent arc instability even after long period lighting by dispersing powders of zirconium carbide, hafnium carbide, and/or titanium carbide in an electrode for discharge lamp in which a metal oxide is dispersed. CONSTITUTION:Powders of zirconium carbide, hafnium carbide, and/or titanium carbide together with an emitter material are dispersed in an electrode main body.
