Title: Collet chuck device of automatic lathe
Inventor: SUZUKI DAISUKE
IPC: B23B31/20
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To reduce a rotational difference between a shifter and a chuck claw as much as possible, and reduce abrasion of an outer peripheral surface of the shifter by pressing a small diameter part of the shifter by the chuck claw. SOLUTION: Even when a grip of a work is released, a shifter 15 is put in a condition of pressing its small diameter part 15b by a chuck claw 11. That is, it is put in a condition where spring force of a coil spring 27 acts on the shifter 15 through the chuck claw 11. Therefore, even if a spindle 3 starts acceleration and deceleration, a large rotational difference is not caused between the chuck claw 11 and the shifter 15. Since the shifter 15 is pressed by spring force of the coil spring 27 through the chuck claw 11, it rotates in synchronism with it when the spindle 3 rotates. Therefore, abrasion between the chuck claw 11 and the shifter 15 is also sharply reduced.

Title: Chemical etching method of semiconductor wafer
Inventor: IMAIZUMI JUNICHI
IPC: C09J7/02
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent corrosion of a device caused by creeping of etchant at the time of spin etching, by making the shape of an adhesive film slightly smaller than the outer periphery of a semiconductor wafer. SOLUTION: A film of polyolefine of polyethylene or the like or a film of polyester such as polymer of them is used for base material of an adhesive film. Both a single layer and a laminate of two or more layers can be used. For the purpose of preventing the curl of a wafer generated at the time of etching, a film such as PET whose elastic modulus is high is preferable. When the above adhesive film is applied to a semiconductor wafer, the adhesive film is made smaller than the outer periphery of a semiconductor wafer as an object on which the film is to be stuck. At least 1.0 mm is necessary for a distance, i.e., overhang, from the end part of the adhesive film to the semiconductor wafer. For the purpose of preventing spinout of the semiconductor wafer at the time of spin etching, the amount of overhang is preferably uniform.

Title: Analysis of interface by abnormal refracted light
Inventor: INABA HIROYA
IPC: G01N21/41
Filed: 1988-06-16
Abstract: PURPOSE:To detect the fine change of an interface with high sensitivity by projecting light on the interface where a liquid is in contact with gas to measure the generated abnormal light transmitted in a direction disobedient to a law of refraction. CONSTITUTION:A triangular groove is formed by transparent glass 1 to allow a fluid to flow and laser beam is projected on the point B on an interface from a point A and totally reflected from the point B to be allowed to follow e beam path of A-B-C. When both of a gaseous phase and a liquid phase are uniform, no abnormality is generated in the interface and, therefore, an optical phenomenon is generated according to a law of refraction and no light is transmitted to the optical sensor 2 provided on a gas side at all. However, when a very small amount of foreign matter is contained on the gas or liquid side to move to the interface, abnormal light disobedient to the law of refraction is leaked to the gas side. The degree of the intensity or polarization of said light is detected by the optical sensor. By this method, the weak variation of the interface generated on a level counting a molecule can be measured and the development of a highly sensitive optical analyser becomes possible.

Title: Waste water treatment
Inventor: MANABE KAZUAKI
IPC: C02F3/08
Filed: 1978-12-05
Abstract: PURPOSE: To drastically reduce the amount of active carbon to be added by specifying the ranges of the concentrations of active carbon and active sludge both present in the aeration tank.  
     CONSTITUTION: In an active sludge treatment of waste water in an aeration tank in the coexistance of active carbon powder, the sum of concentrations of active sludge and active carbon (MLSS) is specified to 25,000ppm or more with the concentration of active carbon to 20,000ppm or more. This means deteriorated active carbon and surplus sludge are not disposed before MLSS value reaches at least 25,000ppm (with active carbon being about 20,000ppm). Successive operation should be continued while maintaining this high value. In this way, the process greatly reduces the amount of active carbon to be added newly as compared with the conventional process.

IPC: H04B1/04
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive radio circuit that can stably control transmission power without increasing the cost, even when a large standing wave is generated. SOLUTION: A level detection section 2 is provided on a transmission line tying an antenna 1 and a power amplifier 3 and detects distributed levels via a plurality of connecting points 2a-2c. When matching of the antenna 1 is deteriorated and a standing wave is produced between the antenna 1 and the power amplifier 3, different levels are detected from connection wires 2a-2c. A control section 51 detects deterioration in the matching of the antenna 1, on the basis of the difference among the detected levels through the connection wires 2a-2c, and when a level difference higher than a preset prescribed level takes place, the control section 51 detects a control voltage level of a modulator 4 to maintain the voltage level of the modulator 4 before the level difference exceeding, of the prescribed level.  Thus, transmission reaching abnormal power level is prevented, and distortion in an output of the power amplifier 3 due to excessive output amplitude from the modulator 4 is prevented in advance.

Filed: 1987-06-17
Abstract: PURPOSE:To erase and operate memory information positively by forming a light-transmitting conductive material layer as a wiring for an electric signal in the upper section of a semiconductor element. CONSTITUTION:A wiring layer 21 being electrically connected to an N<+> type drain region 4c and controlling and driving an EPROM element consists of a light-transmitting conductive material such as an indium tin oxide (ITO), not aluminum. An Mo film 22a and an Al-Si film 22b are interposed between the wiring layer 21 and the N<+> type drain region 4c in order to acquire an ohmic between the wiring layer 21 composed of the ITO and the drain region 4c. Consequently, the semiconductor element can be irradiated with beams projected from an upper section through the wiring made up of a light- transmitting conductive material layer. Accordingly, stored information can be erased or operated positively without increasing the irradiation time of beams and requiring a light source having a high output even when the degree of integration is improved.
