Title: Engine
Inventor: HITOMI MITSUO
IPC: F02D15/04
Filed: 1991-06-28
Abstract: PURPOSE:To improve thermal efficiency by providing a subchamber opened to a combustion chamber, mounting a subchamber valve to an opening of this subchamber, opening the subchamber valve in an intermediate period of a compression stroke, and closing the subchamber valve in the end of the compression stroke or in the beginning of an explosion stroke. CONSTITUTION:A subchamber 10 is formed in an engine 1 to open a subchamber port l0a to a combustion chamber 14. A subchamber valve 11 is arranged in the subchamber port 10a opened and closed. Close timing of this subchamber valve 11 is set to ABDC160deg equal to the ignition timing so that the valve is opened about 70deg before this close timing. Thus by opening/closing the subchamber valve 11 in a compression stroke, a mixture in the combustion chamber 4 is partly confined cooled in the subchamber 10 to replace partly a mixture in the combustion chamber 4 with this cooled mixture in the next compression stroke. Accordingly, a temperature in a cylinder is decreased to improve thermal efficiency.

Abstract: PURPOSE:To enable the cleanliness and smoothness of a glass substrate to be maintained by applying a surface etching process and removing a ground debris after polishing the glass substrate, and forming a SiO2 film on the surface of the substrate for the flattening thereof. CONSTITUTION:After the final polishing process of a glass substrate 1 composed of quartz or the like, the surface thereof is subjected to an etching process, using a solution having an etching effect on quartz.

Scratches 2 remain on the surface of the synthetic quartz glass substrate 1, and include such scratches as generated and expanded at surface polishing and etching processes. Also, the fine irregularities 3 generated at the time of a tapering process are left on the end of the substrate 1. However, the scratches 2 and irregularities 3 are filled with the CVD SiO2 film, and the surface of the substrate 1 is thereby flattened and smoothed.

Filed: 1980-12-25
Abstract: PURPOSE:To obtain ultrashort light pulses using wide gain bandwidth effectively by a DC power source only by a method wherein a self-pulsation characteristic possessed by a semiconductor is utilized and the end surface of a semiconductor laser is made no reflection to oscillate pulses in external cavity mode. CONSTITUTION:A semiconductor laser 3 accidentally generates self pulsation SP or constantly generates the self pulsation SP by deforming structure. The frequency f1 is directly proportional to (I/Ith-1)alpha. Where, I is driving current, Ith is threshold current, and alpha is approximately 1/2. And an external oscillator with a length of L is provided and modulation is done from outside by a resonance frequency fc=C/ZnL (where, c is the velocity of light, n is refractive index) and the phase between axis modes is mutually locked to generate narrow pulses. fr= fc is achieved by adjusting the current I and the end surface 4 is covered with Al2O3 to form no reflection status and pulses are oscillated in external cavity mode to pass the end surface 4 and to reflect by a mirror 5. Then, pulses with a period of t=2Ln/c are obtained. In this composition, short light pulses are obtained by effectively using the wide gain bandwidth of a laser by a DC power source only.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a KANA (Japanese syllabary)/KANJI (Chinese character) conversion device capable of quickly executing required HIRAGANA (cursive form of Japanese syllabary) conversion by a simple key operation. SOLUTION: When a HIRAGANA character string is inputted from an input means, the HIRAGANA character string (1) is displayed on a display device, and when a HIRAGANA conversion key is depressed, the character string is converted into a KANJI/KANA mixed sentence (2). When the HIRAGANA conversion key is depressed again, a conversion range is converted into a HIRAGANA display (3), and when the HIRAGANA conversion key is furthermore depressed, the conversion range is extended (4). Thus HIRAGANA conversion is executed only by repeatedly depressing the conversion key and the HIRAGANA display part is successively extended. Consequently KANJI/KANA mixed sentence can be efficiently converted into a HIRAGANA display. In addition, the conversion range can be simply converted also into a KANJI/ KANA mixed sentence only by depressing the conversion key.
