Title: Printing of dichromatic thermal recording material
Inventor: YOSHIDA MITSUHIRO
IPC: B41M5/28
Filed: 1984-05-09
Abstract: PURPOSE:To prevent mixing of colors by arranging a low-temperature color formation layer to form color with a heat printing plate controlled above the color forming temperature thereof or below the color forming temperature of a high temperature color formation layer while a high-temperature color formation layer is made to form color by a heat energy pulse. CONSTITUTION:A low-temperature color formation layer is made to form color with a heat printing plate while a high-temperature color formation layer to form color with a thermal head adapted to generate a heat pulse below 5ms. Thus, a clear and high-density color formation is possible without mixed colors. As heating energy for the low-temperature color formation layer can be controlled in the temperature, the color forming temperature of the high-temperature color formation layer can be brought closer to the low-temperature color formation layer (minimizing the difference) thereby reducing the mixed color due to heat diffusion.

Title: Manufacture of photosensitive resin
Inventor: ICHIMURA KUNIHIRO
IPC: C08F2/44
Filed: 1983-05-24
Abstract: PURPOSE:To obtain a photosensitive resin having high sensitivity, superior thermal stability and high resolving power and independent of oxygen in the air by reacting a specified monoester salt with polychloromethylstyrene. CONSTITUTION:A p-phenylenediacrylic diester represented by formula I (where R1 is H or CN, and R2 is 1-7C alkyl or benzyl), e.g., dimethyl p-phenylenediacrylate is hydrolyzed with an alkali hydroxide such as KOH to prepare a monoester monocarboxylate represented by formula II (where R1 and R2 are said R1 and R2, respectively, and M is an alkali metal). This monoester salt is reacted with a (co)-polymer of chloromethylstyrene without carrying out purification to manufacture a photosensitive resin. This photosensitive resin has superior photosensitivity, thermal stability and resolving power, and it is used as a photoresist in the manufacture of a printed wiring board and IC. Since the resin has especially high sensitivity and is not affected by air, it is effective in the manufacture of IC by a projection exposure system.

Title: Vacuum pump
Inventor: KABASAWA TSUYOSHI
IPC: F04D29/54
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce incurring of a loss to the tip part of a rotor vane arranged on the inlet side and to improve exhaust performance. SOLUTION: A rotor body 61 has a rotor vane 62 formed in a multistage and consists of a plurality of rotor vanes. The topmost stage rotor vane 62a formed at the rotor body 61 is arranged in the position of the conical part 13 of the casing 10, and its tip is formed at the same inclination angle as that of the conical part 13. This constitution causes gas molecules, accelerated by the tip of the rotor vane 62a, to hardly collide with the casing 10 in a gas molecule region and since the molecules are prevented from residence, lowering of exhaust performance at the tip part is suppressed. Further, by situating the topmost state rotor vane 62a at the conical part 13, the gas molecules are high-efficiently conveyed to the outer peripheral sides of the rotor vanes 62 on and after a second stage.

The voltage E3 is controlled so that the induced voltages of the electrodes 12 and 14 become 0. A voltage E2 which has the same waveform as that of the voltage E3 is applied on an electrode 13 of the capacitor C2. The capacitance of the capacitor C2 and the level of the voltage E3 are adjusted so that the voltage E3 becomes 0 when a displacement to be measured is 0. Thus, the stability and the temperature characteristic of the length measuring machine are improved, and the high measuring accuracy is obtained.

Abstract: PURPOSE:To control a combustion furnace with a very simple signal processing by converting a level variation in vibrational energy of low-frequency and high-frequency components of a micro-vibration growing in slow combustion and intense combustion. CONSTITUTION:A micro-vibration component only is taken out by inputting an output signal of a micro-vibration detector into an AC coupling circuit, eliminating a D.C. component by a furnace pressure to take out only a micro-vibration component. Said output is entered into a low-pass filter 8 and a high-pass filter 9. At the low-pass filter 8, the low-frequency range component of the micro-vibration which grows during a preset slow combination, is taken out of the output signal of the low- pass filter 7, while at the high-pass filter 9, the component of the frequency range higher than the low-frequency range of the micro-vibration is taken out of the output signal of the low-pass filter 7. These output signals are rectified and smoothed, and then fed into a divider 12 to obtain a signal for combustion control.
