Title: Laser generator
Inventor: SAITO KIYOSHI
IPC: H01S3/05
Filed: 1987-01-10
Abstract: PURPOSE:To reduce the ambient temperature dependency of a laser oscillation output by forming a cold gas connecting tube by providing a control means inhibiting heat gains from an ambient atmosphere. CONSTITUTION:A heat-insulating material 19 having thermal conductivity smaller than a cold gas connecting tube 14 is mounted on the outer circumference of the cold gas connecting tube 14. Consequently, heat gains from an ambient atmosphere are inhibited in the cold gas connecting tube 14 and the temperature of a cold gas fed to a laser head section 1 is hardly affected by an ambient temperature and can be kept at a sufficiently low value, thus reducing the ambient temperature dependency of a laser oscillation output, then improving the output stability of a laser generator, provided that an output maximum value can be increased. A practically enough effect can be displayed only by setting up the heat-insulating material 19 consisting of a foamed rubber or a foamed plastic material in thickness of 25mm onto the surface of the cold gas connecting tube 14 having an outside diameter of 0.075m and length of 2m at that time.

IPC: H01L21/68
Filed: 1992-01-13
Abstract: PURPOSE:To prevent dust from attaching to a wafer when a position of an orientation flat is recognized by arranging a pair of a light emitting device and a photosensor at each specified position at both ends of a wafer cassette in an alignment direction. CONSTITUTION:A semiconductor laser oscillator 7 is arranged on a main body 6 whereon a storage case 3 is mounted and laser 7a is irradiated at a specified position wherein the position of an orientation flat 2a of a wafer 2 is registered through a plurality of optical fibers 8 arranged horizontally. A plurality of light emitting diodes 9a are arranged in opposition thereto. A wafer cassette 1 wherein the wafer 2 is aligned is contained in a wafer storage case 3 and mounted on a main body 6 and the semiconductor laser oscillator 7 is driven. In a part wherein an irradiation path of the laser light 7a is screened by a part of the wafer 2, all the laser light 7a is not received and the light emitting diode 9 does not react at all or emits light partially; therefore, by seeing this, it is possible to recognize existence of the wafer 2 wherein a position of the orientation flat 2a is not registered without taking the wafer out of the wafer storage case 3.

Title: Air intake port of internal-combustion engine
Inventor: SAEGUSA SHIYOUGO
IPC: F02B31/00
Filed: 1982-01-13
Abstract: PURPOSE:To produce a strong swirl by forming an air intake passage in such a way as its center line runs nearly parallel with a sheet surface of an air intake valve and the terminal part of an annular passage is extended so as to almost circle round a valve shaft and further it is tapered toward the sheet surface so as to avoid its communication with said intake passage. CONSTITUTION:Since an air intake passage 3 runs about parallel with the sheet surface 7, intake air flowing into an air intake passage 3 from an air intake port 3a grows larger in its velocity component Vx. Accordingly, the velocity component Vx of the intake air can be effectively converted into the velocity component in the turning direction in the combustion chamber 5. The terminal part 4A is tapered toward the sheet surface 7 so as to avoid its communication with the air intake passage 3 side, therefore, a turning flow running through a ring passage 4 flows into the combustion chamber 5 without joining the flow from said intake passage 3.

Title: Controller of semiconductor laser
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B7/00
Filed: 1985-01-11
Abstract: PURPOSE:To obtain a device which stabilizes a peak output in a short time by providing a means which performs forward control over the amplitude of the modulating pulse current of a semiconductor laser after the start of pulse modulation. CONSTITUTION:The peak output side and bottom output side of the output voltage of a preamplifier 3 when pulse modulation is imposed upon the semiconductor laser are sampled and held by the 1st and the 2nd sample holding circuits 7 and 8 in a period of two starting pulses and the amplitude of the modulating pulse current is varied thereafter according to their held vales. At this time, the starting time of the pulse modulation of a modulating signal is detected and a reset signal is sent to a semiconductor laser driving circuit 11 in the period of two pulses. The semiconductor laser driving circuit 11 receives the reset signal from a timing circuit 12 and superposes such a modulating pulse current that the peak output monitor voltage of the semiconductor laser is a peak output monitor voltage VP upon a bottom output driving current at the start of the pulse modulation. Consequently, the peak output when the semiconductor laser is pulse-modulated is controlled and stabilized in a short time.

Abstract: PURPOSE: To promote the capacity of a pump by opening a passage connected to an oil reservoir in a bypass passage and providing a thermally responsive device in this passage for opening the passage when the temperature of a working oil is excessively raised.  
     CONSTITUTION: A passage 60 connected to an oil reservoir is opened in a bypass passage 26 connecting between a valve chamber 41 and a suction passage, and a thermally responsive device 61 is provided in this passage 60. When the temperature of the working oil is abnormally raised by the continuous relief operation of a discharge-regulating valve 40, the passage 60 is opened to return a part of the working oil from the valve chamber 41 into the oil reservoir, and new cool working oil in the reservoir is conducted into the suction passage as pressure in lowered in the bypass passage 26 by virtue of that returned working oil. In this construction, the working oil circulating in a pump can be prevented from the sudden rising of the temperature. Consequently, the pump is prevented from the seizure of a sliding member and deteriorations of a sealing member and the working oil, and improved in its performance.

Title: Artificial turf
Inventor: TANAKA NOBUHIRO
IPC: E01C13/00
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To improve water permeability by providing an elliptical or slot-shaped water permeable hole on a synthetic resin substrate and specifying the size of a granule to cover the water permeable hole. SOLUTION: Synthetic resin turfs are planted on a substrate made up of a synthetic resin ground fabric 11 and a synthetic resin packing layer 12 provided on the reverse of the synthetic ground fabric and elliptical or slot-shaped water permeable holes 13 are provided on the substrate 1 and grains made up of crushed stone are filled between turfs to form artificial turfs. On this occasion, as the shape of the water permeable holes 13 are elliptical or slot- shaped, the breadth is smaller than the diameter of the water permeable holes, the outflow of granules 3 from the permeable holes 13 is restricted. Subsequently, the size of a granule 3 covering a permeable hole 13 is 30% or higher and 100% or lower than the breadth of the permeable hole 13.  Therefore, the granules 3 are kept from flowing out the permeable holes 13 by the bridging action of the granules 3, and the blocking of the permeable holes 13 is controlled, thereby increasing water permeability.

Title: Optical system driver
Inventor: MIYAJIMA GIICHI
IPC: G02B7/04
Filed: 1986-01-14
Abstract: PURPOSE:To drive an optical system with high accuracy by forming a support member into a curved arm shape and providing a piezoelectric element into a space enclosed by said support member. CONSTITUTION:When the voltage is impressed to a piezoelectric element 101, the element 101 has a mechanical strain and is displaced in the direction A-A'. This displacement is transmitted to the direction (a) of a frame body part 102a via a head 103 attached at the tip part of the element 101. Then the displacement degree is mechanically amplified by the part 102a. In other words, a point of force produced by the head 103 is set closer to the fulcrum side than the position of a hinge part 102d serving as an action point with the position of a hinge part 102e defined as a fulcrum. Thus the displacement degree of the element 101 is amplified by the action of levers and transmitted to a support member 102. The end face of the part 102a is fixed to a base 111 and therefore an optical system holder attachment part 102b is displaced in the direction (b), e.g., the tracking direction with a shaft hole 102c defined as the center of a curvature radius. The distance between the action point and the the hole 102c is smaller than that between the part 102a and the hole 102c. Therefore the displacement of the element 101 is amplified further at the part 102b.

Abstract: PURPOSE:To eliminate an error signal having 30Hz cycle which appears at a control signal for the tracking phase in a tracking controller using four types of pilot signals different in frequencies, by using a head switching pulse to produce an error erasing signal. CONSTITUTION:The pilot signal is sampled through an LPF15 for reproduction signals fed from rotary magnetic heads A and B. Then these reproduction signals undergo the balanced modulation through a balanced modulator 16. Thus the signals of frequency components 3fH and fH are obtained, and the differential is supplied to a BPF28 as a phase control signal S1. Then an error signal S2 having 30Hz cycle is extracted. The resistance division output of a head switching pulse Ps is supplied to a terminal of a subtractor 30 as an error erasing signal S3. Then a capstan motor 26 is driven by the signal S1 which is free from the signal S2.
