Patent JP-H0278814-A (JP)
Title: Burner
Inventor: NAKAMOTO MITSUYOSHI
IPC: F23D14/02
Filed: 1989-06-02
Abstract: PURPOSE:To enable formation of the laminar flow of flame and to stabilize flame by a method wherein slit burner ports are employed, and flame is bent in the direction of a combustion chamber outlet by means of combustion gas. CONSTITUTION:Fuel and primary air are mixed together to produce fuel-air premixture, which is fed to a fuel branch pipe 9 and injected through a burner port 5 to a primary combustion chamber 2 after the passage of it through a fuel feed passage 8. Secondary air 18 is fed to a burner cooling passage 12 to cool a primary combustion chamber 19 and a fuel feed passage 8, and is fed through a secondary air hole 7 to a secondary combustion chamber 9. Fuel-air premixture 17 injected through the burner port 5 is ignited to form an opposite flame 15. When the injection speed of the fuel-air premixture 17 is high, the tips of the flames are collided with each other, combustion gas 26 flows in the direction of a combustion chamber outlet 21, and the opposing flame 15 is bent at 15a in the direction of the combustion chamber outlet 21. Since flame is formed by means of the slitform burner port 5, the area of flame making contact with or collided with combustion gas is increased. The opposing flames 15 are positioned opposite to each other at the tips of the flames to improve flame stability, and combustion having low noise and being quiet can take place.

Title: Rotary head type magnetic recording and reproducing device
Inventor: MIYAGAWA NAOYASU
IPC: G11B20/00
Filed: 1989-06-02
Abstract: PURPOSE:To search a sound signal with high accuracy by cue/review by outputting the queue/review sound signal, which is reproduced from an optional track, and the sound signal reproduced from a main track so that there is no time difference mutually between the both sound signals. CONSTITUTION:In a recording mode, a digital signal to be supplied to a rotary head 11 is converted again to an analog signal by a decoding circuit 26 and a DAC(analog/digital converting circuit 27) and supplied to a fixed head 12. In comparison with a signal recorded by the rotary head 11, a signal recorded by the fixed head 12 can be delayed only for a delay time by the decoding circuit 26 in advance and recorded. Then, the delay of a reproducing output signal from a rotary head system in a reproducing mode can be canceled. Accordingly, simultaneity is improved between the reproducing output signal of the rotary head system from a reproducing output terminal 17 and the reproducing signal of the fixed head system from a queue/review output terminal 19. Thus, the sound signal from the cue/review (fast forward / rewinding reproducing) output terminal 19 accurately executes program searching.

Title: Semiconductor integrated circuit
Inventor: YAMADA MICHIHIRO
IPC: G11C11/34
Filed: 1985-06-27
Abstract: PURPOSE:To prevent generation of a crack in plastic resin at a semiconductor integrated circuit such as a dynamic MOS RAM, etc. by a method wherein sense amplifiers only are covered with buffer coates. CONSTITUTION:Because buffer coats 12 and plastic resin 10 come in contact mutually with extremely small areas, concentration of internal strss is not generated according to quality of the meterial of the buffer coates 12. Because a silicon chip 1 and plastic resin 10 have favorable adherence, internal stress is dispersed to be applied to the points A-B, the points E-F and the points CD. Accordingly, formation of a crack in the plastic resin 10 is hardly generated even when an extremely thermal stress test is performed. A dynamic MOS RAM is a device sensitive to internal stress to be generated in the plastic resin 10, especially the sense amplifiers 6 thereof are sensitive, and by covering only the sense amlifiers 6 with the buffer coats 12, an effect to relieve stress is obtained.

Title: Ink jet printer and printing method
Inventor: KOITABASHI NORIFUMI
IPC: B41J2/205
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To enhance print quality, including increase of density, while allowing shift even if ink dots are superposed while being shifted by causing a black ink to react on a color ink having different polarity at a density lower than that of a color ink having higher brightness thereby forming a black image. SOLUTION: At the time of printing a character with black (BK) ink, cyan (light cyan) ink of low color density is superposed entirely or partially on an image of black ink. If anion based BK ink is employed, cation based light cyan ink having different polarity is employed so that both inks are mixed on a print medium to render the coloring matter insoluble or to cause aggregation. Consequently, even if superposition of ink dots deviates from a specified range, it cna not be recognized visually and the density of black image can be increased by adding the coloring matter of C to a BK pixel.
