Title: Speaker on board car
Inventor: SATOU MASAHIRO
IPC: H04R1/02
Filed: 1981-10-01
Abstract: PURPOSE:To make a car-loading speaker compact and improve its tone quality by arranging a number of plane wave plane driving type speakers almost in the same plane adjacently, connecting them in parallel, constituting a single speaker unit, and arranging the required number of speaker units. CONSTITUTION:Circular holes are provided on the plate 11 of a sun visor 1 and a number of plane wave plane driving type speakers SP1 to SP8 are mounted on them. A flexible cushion material 13 is arranged between the plate 11 and a cover 12. Besides, this speaker unit is mounted on the right and left sun visors 1 in a car as a stereo unit. As a result, since sound comes from the front of hearers, the position of a sound source is not unnatural. Further, since the tone quality caused by the excessive inclination of the speaker for the hearers is not deteriorated and sound is produced from both the front and rear of the speaker, the tone quality is not deteriorated even the sun visors are inclined.

Title: Photoresist pattern forming method and photoresist developing device
Inventor: MIYAMA HIROSHI
IPC: G03F7/30
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of developing irregularity (precise irregularity of pattern size) at the developing time of photoresist. SOLUTION: On this method, a glass substrate 20 is lifted up from a holding tool 23 by a moving frame body 30 so that the temperature of the substrate 20 becomes constant extending over the whole surface in the case that developer 25 is supplied to the substrate 20 at the developing time of the photoresist. The frame body 30 is retreated as soon as the developing time is finished so as to vacuum-hold the substrate 20 by the initial tool 23. Then, a next process is executed, that means, the substrate 20 is washed or dried. By eliminating the effect of the temperature by the tool 23 exerted on the uniformity of the temperature of the developer 25, the occurrence of developing irregularity is suppressed.

Title: Front wheel suspension device of saddle seat type vehicle for rough terrain running
Inventor: ONO YOSHIHIRO
IPC: B60K25/04
Filed: 1986-07-03
Abstract: PURPOSE:To expand the positioning space of an exhaust expansion pipe and to improve the freedom of layout, by pivoting an upper arm at a point of a body frame formed in a plain bar shape. CONSTITUTION:In a front wheel suspension device 11, an upper arm 22, a lower arm 23, a knuckle bracket 24, and a side pipe 2a compose a link of a parallelogram, the upper and the lower arms 22 and 23 move up and down responding to the uneven road surface, the knuckle bracket 24 follows to move up and down, and a shock absorber 26 absorbs the shocks then. In this case, since the upper arm 22 is formed of a single steel pipe and positioned at the front side of the shock absorber 26 of the car, no swaying member exists at the rear side of the car. Therefore, neither the swaying space nor the frame member to hold such a swaying member is necessary at the rear side, resulting in a large space there. As a result, the layout of an exhaust expansion pipe 6a can be selected freely in the space, improving the freedom of layout that much.

Title: Current resonance converter
Inventor: SATO MITSUTAKE
IPC: H02M3/28
Filed: 1990-06-15
Abstract: PURPOSE:To suppress the rated voltages of a switching element and the other to a low value while avoiding a switching loss by combining resonance currents of two resonance circuits to generate a switching current, and forming a switching current waveform to a waveform similar to an ideal trapezoidal wave. CONSTITUTION:A first resonance circuit is composed of a capacitor 171, a leakage inductance 13 and a capacitor 14, and a second resonance circuit is composed of an inductance 16 and the capacitor 171. A switching current flowing through intermittent means 11 is generated by combining the resonance currents of the two resonance circuits. The switching current has two peak values at each switching period, rises and falls without abrupt change during a period of a low level, and becomes similar to a trapezoidal wave. Accordingly, the rated voltages of the switching element and the other can be suppressed to a low value, and an element scale can be reduced.

IPC: D21H11/20
Filed: 1997-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for improving the water filterability of pulp, enabling to enhance the water filterability of the pulp and facilitate a paper-making operation from the pulp by treating the pulp with an α-1,4-glycoside decomposing enzyme in a wet state. SOLUTION: This method for improving the water filterability of pulp comprises simultaneously or successively treating a pulp slurry low in water filterability with a strach-liquidizing enzyme and a starch-saccharizing enzyme which are α-1,4-glycoside-decomposing enzymes, preferably in amounts of 0.01-1%, more preferably 0.03-3%, subsequently, based on the absolutely dry amount of the pulp. The pulp slurry low in the water filterability contains viscous substances comprising polysaccharides such as starch, dextrin and similar polysaccharides, having α-1,4-glycoside bonds, and includes a pulp obtained by digesting the crude fibers of old banana trees by a craft pulp method. Thus, the polysaccharides are selectively decomposed to lose the high viscous property, thereby improving the water filterability of the pulp.

Title: Blowoff nozzle for wind tunnel
Inventor: YAMAGUCHI TSUTOMU
IPC: G01M9/04
Filed: 1991-06-28
Abstract: PURPOSE:To reduce the noise generated at the rear edge of the inside nozzle wall forming a blowoff nozzle to a large extent by dividing the passage reaching a blowoff orifice from a gathering tunnel into a main flow part passage and the annular part passage surrounding the main flow part passage. CONSTITUTION:In a blowoff nozzle 2, two passages, that is, a main flow part passage 25 and the annular part passage 26 surrounding said passage 25 are formed by an inside nozzle wall 24 and an outside nozzle wall 23. The passage 26 is constituted so that the flow velocity distribution thereof becomes gradually small toward the outside in the radius direction of the passage 26. In order to obtain this flow velocity distribution, the wall 24 may be formed into a double structure or a resistance object such as a metal net may be arranged in the passage 26. By this constitution, the flow velocity difference between the passages 25, 26 at the rear edge of the wall 24 is sufficiently small and a sufficiently weak shearing stream is obtained and, therefore, a discharge vortex can be weakened and the noise generated from said rear edge is reduced. Since the flow velocity inside the wall 23 forming the passage 26 is made sufficiently low, the noise generated from the rear edge becomes extremely low.
