Title: Heat fixing device
Inventor: YAMASHITA KEITAROU
IPC: H05B3/00
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a practically uniform heating temperature throughout the overall length of a heat roll by setting plural electrode rings on both ends of the heat roll and bringing a pressure roll and the heat roll into contact with each other between the two rings nearest to the center of the heat roll out of these electrode rings. CONSTITUTION:When a heat roll 1 and a pressure roll 2 which are pressed to each other are rotated by a driving mechanism which is not shown in Fig. and a voltage is applied to a feeding brush 13 by, for example, a commercial AC power source, a current is flowed to a part having with l1 of a resistance heating body 8 through electrode rings 9b and 9'a, and the current is flowed between the electrode rings 9a and 9b and between the rings 9'a and 9'b also. The current flowed to the resistance heating body 8 is as shown by solid-line arrows or broken-line arrows in Fig. Since not only the center part having the width l1 but also part having the width l2 in both ends of the resistance heating body 8 are heated, the temperature distribution on the surface of the heat roll 1 is kept uniform practically in the axial direction to correct the fall of temperature in both ends. Consequently, when a supporting material 16 holding a toner image 15 is allowed to pass through a nip part between the heat roll 1 and the pressure roll 2, a high-quality fixed image is obtained without a fixing defect in both end parts.

Title: Manufacture of complementary type mis transistor
Inventor: KUDO NOBORU
IPC: H01L21/8238
Filed: 1985-03-07
Abstract: PURPOSE:To decrease one process in comparison with conventional photolithography processes, by performing low concentration diffusion of an NMOS without making a PMOS. CONSTITUTION:In a PMOS forming region 14, a P<+> diffused layer 7 for a source and drain is formed by, e.g., boron-ion implantation, with a field oxide film 3 and a poly Si gate 6 as masks. Masking is performed by resist 5 having a thickness of about 1mum so that boron does not enter into an NMOS forming region 13. Then, the resist 5 is removed, and thereafter, e.g., phosphorus ions are implanted in order to form low-concentration source and drain of the NMOS with the poly Si gate 6 and the field oxide film 3 as masks. Thus an N<-> diffused layer 8 is formed. Since the masking of the PMOS forming region 14 is not performed, phosphorus is implanted in the P<+> diffused layer 7. Owing to the low concentration diffusion, however, the effect of the P<+> diffused layer 7 on the carrier concentration is negligible.

Title: Plasma powder body cladding torch
Inventor: HOSHINO TADASHI
IPC: B23K9/26
Filed: 1988-02-27
Abstract: PURPOSE:To prevent the adhesion of a powder body onto the nozzle peripheral side by forming the recessed part aligning the shape of the opening part of the outlet port of a powder body hole to the face orthogonal with the axial direction of the powder boyd hole on the face opposing to the base metal of a nozzle member. CONSTITUTION:On the face 15 opposing to the base metal of a nozzle member 10 a recessed part 13 is formed at its center part, having a trapezoidal shape at its vertical cross section and one end 12a of a hole 12 is opening at the part of its slope 14. The slope 14 is inclined at about 45 deg. to the face 15 and the opening part 12a of the slope 14 side of a hole 12 becomes orthogonal with the axial direction of the hole 12. Therefore, the flow velocity of a powder body and powder carrier gas becomes uniform at the opening part 12a of the hole 12 and the vortex caused at the part thereof is small as well, so the possibility of the powder body sticking to the nozzle vicinity is reduced.

Title: Method and apparatus for electron-beam lithography
Inventor: OKUMURA MASAHIDE
IPC: H01L21/027
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To improve the deflection response characteristic of an electron beam caused by a deflection delay or by an advance factor by a method wherein a correction waveform as the difference between a first waveform at a time when an electron beam is deflected on a mask and a second waveform at a time when the electron beam is deflected to an edge part on the mask is added to a deflection control signal. SOLUTION: An electron beam 1 is deflected toward a point A4 on a mark from a point A0 at a prescribed distance from the mask, and a first waveform B2 is obtained. Then, the electron beam is deflected to the jump starting point AO, a sufficient time which does not affect a deflection delay is awaited, the electron beam is then deflected to an edge part A2 on the mark, and a second waveform C2 as a mark edge waveform is obtained. When the second waveform C2 is subtracted from the first waveform B2, a third waveform (a response delay waveform) C3 is obtained. The third waveform C3 is added to a deflection waveform, and the magnitude and the polarity are controlled so as to reduce the third waveform C3 to a minimum. Then, the time elapsed until the deflection waveform at this time reaches the point A4 on the mark is shortened.

Title: Manufacture of matted biaxially stretched polyethylene film
Inventor: MISHINA NORITOSHI
IPC: B29C55/00
Filed: 1983-03-22
Abstract: PURPOSE:To obtain a matted film having a desired matting, by stretching longitudinally a polypropylene film, and coating the surface thereof with an aqueous resin dispersion that will exhibit ununiform stretching behavior when lateral stretching is effected. CONSTITUTION:A polypropylene film is stretched longitudinally into a longitudinally stretched sheet. The surface of the sheet is coated with a resin in the form of an aqueous dispersion that will exhibit ununiform stretching behavior when lateral stretching is effected, and the surface is dried by hot air to remove the moisture to form a resin coating thereon. Then this film is stretched laterally under heating. Thus a matted film is obtained wherein the resin coating is roughened in the course of the lateral stretching. The resin used can be produced for example by mixing emulsions of resins such as styrene type resins resins and acrylic resins having different crystallinities, melting points, etc. so that a desired matting can be acquired.

Title: Coding system
Inventor: ONO FUMITAKA
IPC: H03M7/40
Filed: 1990-02-26
Abstract: PURPOSE:To obtain a high coding efficiency by adopting the constitution such that the allocation area of a major symbol MPS is always larger than the allocation area of a minor symbol LPS. CONSTITUTION:When a minor symbol area (S) selected from tables having plural values from the state of a Markov information source is inputted to a prediction estimating section, a difference Ai-1-S with a range Ai-1 of a preceding symbol stored in a register is obtained by a subtractor 2 and the result is outputted. A comparator 7 compares the quantity between the difference Ai-1-S with the minor symbol S inputted directly and outputs the result as E. On the other hand, a switching device 8 selects either the inputted difference Ai-1-S or the range S based on an MPS/LPS being an output decided by the prediction estimating section as to whether the output is the major symbol or the minor symbol in the Markov information source and on the output E of the comparator 7 resulting from the inputted difference Ai-1-S or the range S as the range with respect to the current symbol.
