Title: Smoke sensor for clean room
Inventor: KASE TAKAO
IPC: G08B17/107
Filed: 1984-11-20
Abstract: PURPOSE:To detect low-density smoke in a clean room with high sensitivity by sucking air from the clean room into a dark box, and irradiating the inside of the dark box with light from a light emitting element and detecting scattered light from smoke particles by a photodetecting element. CONSTITUTION:The air in the clean room is sucked into the dark box 5 continuously through a suction port 6 and discharged from a discharge port 8. The inside of the dark box 5 is irradiated with the light from the light emitting element 10 and the light is photodetected by the photodetecting element 12 to detect scattered light from smoke particles. Its detection value is inputted to a control circuit 14 and a warning is transmitted to a fire receiving board 15 and disaster prevention device 15 when the detection value exceeds a specific value. Thus, the air in the clean room is sucked positively to detect even low- density smoke right after firebreaks out.

Title: Method of forming ultrafine hole pattern
Inventor: GOTO HIROSHI
IPC: H01L21/768
Filed: 1984-11-20
Abstract: PURPOSE:To enable to form a pattern accurately and readily by anisotropically etching the third layer, allowing the thick film portion to remain in the hole side of the second layer, controlling the width of the hole, and then anisotropically etching with the same etching rates of the first layer with it as a mark. CONSTITUTION:A silicon dioxide is laminated on an Si substrate 11 as the first layer 12, a polysilicon is then laminated by a CVD method as the second layer 13. An electrode window is opened at an etching speed larger than an SiO2 for forming the first layer by reactive ion etching from the layer 13 of the portion to be formed with the normal photoresist as a mask. A polysilicon layer is formed by a CVD method on the patterned polysilicon layer as the third layer 14, and then etched until an electrode window is formed on the first layer at an etching speed larger than the SiO2. Thus, since no irregular film thickness if formed irrespective of the stepwise substrate, the irregularity of the width of the hole by the etching can be prevented to always obtain the hole of stable width.

Title: Controlling method for water turbine inlet valve
Inventor: KAMIMURA YOSHIO
IPC: F03B3/00
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To smoothly exhaust air within a spiral casing without providing an automatic air vent valve by temporarily stopping a valve at a small opening at the time of an opening direction operation of an inlet valve of a vertical-shaft water turbine having the spiral casing and continuing an opening operation again after prescribed time elapses. SOLUTION: An inlet valve 3 temporarily stops to operate at a small opening, the opening is held for prescribed time and subsequently an opening operation is performed again. As a result, air b1 left within a spiral casing 3 passes through an inlet valve 2 and a hydraulic iron pipe 1 little by little while the opening operation of the inlet valve 3 is stopped and can be passed through to an upper pond or a dam. Thus, air b1 does not dash up within the hydraulic iron pipe 1, air b1 does not cause a water hammer and air b1 does not impart large shaking to the upper pond or the dam water surface.

Title: Production of film to be deposited by vaporization
Inventor: YASUJIMA HIROYUKI
IPC: C23C14/56
Filed: 1991-09-26
Abstract: PURPOSE:To stably produce a high-quality film to be deposited by vaporization with excellent thermal conversion efficiency by making ceramics material to be deposited by vaporization into an aggregate having a specified shape in the case of irradiating this ceramic material to be deposited by vaporization with electron beams and vaporizing it to produce the film to be deposited by vaporization. CONSTITUTION:Transparent ceramic material 1 such as SiO2 to be deposited by vaporization is introduced into a rotary hearth 2. The inside of a vessel housing the rotary hearth 2 is exhausted and evacuated by a vacuum pump 8. A base material film 7 such as polyethylene is unwound from an unwind roll 6 in the inside of the vessel and wound around the outer circumference of a cooling roll 9 and thereafter wound around a wind-up roll 5. On the way thereof, the material 1 to be deposited by vaporization is heated and vaporized by irradiation of electron beams emitted from an electron gun 3 and vapor-deposited on the surface of the polyethylene film 7 on the outer face of the cooling roll 9. Thereby a plastic film made of transparent SiO2 is formed. In this case, the thermal conversion efficiency of electron beams is enhanced by making the ceramic material 1 to be deposited by vaporization in the rotary hearth 2 into a shape wherein a columnar aggregate smaller than the diameter in the face irradiated with electron beams 4 is bundled in the incident direction thereof.

Title: Light pulse compressing device
Inventor: NAKAZAWA MASATAKA
IPC: G02F1/35
Filed: 1986-10-20
Abstract: PURPOSE:To obtain a high-output compressed pulse by making a positive chirp pulse to a degenerative four-wave mixing medium incident on a single mode optical fiber as a negative chirp pulse. CONSTITUTION:A light pulse from a light pulse generator 1 is passed through a single mode optical fiber 2 for an incident wave to obtain a positive chirp pulse, which is made incident on the degenerating four-wave mixed medium 4. The degenerative four-wave mixing medium 4 converts the positive input chirp pulse into the negative chirp pulse, which is reflected. Then this output is reflected by a half-mirror 5 to enter a single mode optical fiber 2B for a reflected wave and the pulse is compressed here. Then, the degree of compression of the negative chirp pulse depends upon the inclination of a chirp, but compression to about 1/10 is normally possible. Thus, degenerative four-wave mixing is used to generate the inverted chirp pulse, which can be compressed with high efficiency by single mode normal dispersion.

In the still mode, the reel base 32 on a supply side is driven by a motor 1 and the reel base driving mechanisms 5 and 6. After that instant, the capstan 23 is reversely rotated to shift the tape 54 in a reverse direction. Thereafter, the tape 54 is taken up to the base 32 by the mechanisms 5 and 6. A tension band 61 which is wound around the base 32 is released by the motor 1.
