Title: Method for recording
Inventor: SAEGUSA HIROSHI
IPC: B41J19/18
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To efficiently move a recording head by recording a recording medium while reciprocating the recording head to the recording medium and, determining an end part as a recording start position of a next recording area in accordance with a relative positional relationship of the next recording area to the present recording area. SOLUTION: This control circuit includes a recording head 101, a memory, a driving part for a main motor 103, a driving part for a sub motor 105 and a control part. The control part detects a black pixel position at each end of a line. It is distinguished whether an RP2 which is the black pixel position at a right end of a second printing line is right or left to an LP1, RP1 which is the black pixel position at each end of a first printing line. When the RP2 is right to the LP1, a distance to an LP2 from the LP1 is compared with a distance to the RP2, a required movement time is calculated, and a through down start point is set at either of the LP1 and LP2. Efficiency for moving the recording head 101 is thus enhanced.

IPC: H01L29/78
Filed: 1988-12-08
Abstract: PURPOSE:To increase the durability of a semiconductor device, and improve quality and reliability by interposing a comparatively thick insulating layer only, between a controlling electrode and a semiconductor layer in a peripheral region exposed to severe conditions. CONSTITUTION:In the peripheral region of a semiconductor substrate exposed to severe conditions, the following are interposed between a first semiconductor layer 7 and a control electrode 8; a comparatively thin first insulating layer 4, wherein e.g. a gate oxide film 5 is not present, and a comparatively thick second insulating layer, wherein e.g. a field oxide film 61 only is present. As a result, a step-difference A does not generate. Further, since the insulating film is thick in the peripheral region, the destruction endurance is so large that the destruction of a semiconductor device caused by excess current or excess voltage becomes hard to generate. A device of high quality and reliability in which electric field concentration caused by the step-difference between a gate oxide film and a field oxide film does not generate can be obtained.

Filed: 1987-12-10
Abstract: PURPOSE:To replicate a pattern smaller in size than that on an X-ray mask which is actually formed by suitably selecting a gap between the mask and a sample and the wavelength distribution of irradiated X-ray. CONSTITUTION:A silicon substrate 25 is coated 1mum thick with resist 24, and an absorber pattern 23 of Au is formed 0.5mum line and space on an SiNx 22.

Abstract: PURPOSE:To improve the reliability of connection and sealing of a multichip module, by heating directly a cap which is put on the multichip module by a heating means and fusing solder for sealing located between the cap and a ceramic substrate. CONSTITUTION:A cap 5 is fixed to a heater 7 by using fixing screws 10 so as to make the upper face of the cap come into contact with the lower face of the heater. It is desirable that a high temperature conductive gas such as helium is used as a sealing atmosphere to be introduced in a chamber 8. Then, the operation of a stepping motor 11 makes a ramp 9 go up and this device allows LSI chips on a ceramic substrate 1 that are placed in advance on the ramp 9 to be held in such a state that the chips 3 are pressed up to a thermally conductive members 4 and sealing is carried out by causing solder materials for sealing at a solder sealing part 6 to be fused by heating through the cap 5 with the heater 7. Solder-sealing can be performed by lowering a heating temperature obtained by using the heater 7 up to a temperature approaching the melting point of the solder materials and this approach prevents reflow of a connection part of the LSI chips 3 as well as damage due to heat at the LSI chips 3 and at the ceramic substrate 1.
