Title: Operating method for semiconductor device
Inventor: HIRASE JUNJI
IPC: H01L29/78
Filed: 1994-12-09
Abstract: PURPOSE: To enhance the drive power without increasing the supply voltage or reducing the gate length by applying a positive feedback to the drain current of a MISFET to increase it when the gate voltage of the MISFET exceeds a threshold voltage. CONSTITUTION: A MISFET having a gate 22, a source 24 and a drain 25 is mounted on part of a semiconductor substrate 21. A substrate bias voltage Vbb is applied to the semiconductor substrate 21 through a resistor 4. When the voltage of the gate 22 of the MISFET is higher than a threshold voltage, a positive feedback is applied to the current flowing from the drain 25 to the source 24 of the MISFET to increase the current of the drain 25. This makes it possible to enhance the drive power of the MISFET without increasing the supply voltage or reducing the gate 22 length.

Title: Attraction device for magnetic work
Inventor: INAGAKI HIROYUKI
IPC: B25J15/06
Filed: 1994-12-09
Abstract: PURPOSE: To improve operability etc. by mutually combining a contracting member comprising a non-magnetic member, having a contact face for a magnetic work, and an attraction member comprising a magnetism retaining member, for applying/releasing magnetism for a magnetic work, thereby obtaining compactness of an attraction device. CONSTITUTION: When a magnetic work contained on a pallet is to be attracted by using an attraction device comprising an air-cylinder actuator 10, air is first supplied to an upper pressure chamber of a cylinder 13 from an upper air supply port 12a, so that a piston 14 is lowered and thus a magnet holder 16 is retained at it lowermost position. And then, the lowermost face of plural permanent magnets 20 is brought in contact with a contacting member 32, and so a magnetic work is attracted to external surface 32a. Subsequently, a hand member connected to an upper portion of an attraction device is raised and so the magnetic work is taken out from the pallet and placed at a specific position.  On the other hand, air is supplied to a lower pressure chamber 13b of the cylinder 10 from a lower air supply port 12b, so that the piston 14 is raised and attraction of the magnetic work is released.

Title: Device and method for detecting human body
Inventor: SAITO MASANORI
IPC: G08B13/18
Filed: 1994-12-09
Abstract: PURPOSE: To surely distinguish a high-temperature low-emissivity object from a high-emissivity low-temperature object so as to improve the human body detecting accuracy of a human body detecting device by taking the infrared image of the object in two states, a state where the objects are irradiated with infrared radiation and another state where the objects are not irradiated with the infrared radiation. CONSTITUTION: An extracting/control means CL3 creates a state where an infrared radiating means CL2 emits infrared radiation and another state where the means CL2 does not emit infrared radiation by controlling an infrared image pickup means CL1 and the infrared emitting means CL2. The control means CL3 inputs two pieces of infrared information which are obtained when the pickup means CL1 picks up infrared images in the above-mentioned two states and extracts infrared information in a prescribed temperature zone from the two sets of infrared information. When, for example, infrared radiation is emitted from the emitting means CL2, the images of reflected infrared radiation and infrared radiation emitted from an object itself are picked up in an overlapping state.  When no infrared radiation is emitted, on the other hand, only the image of the infrared radiation emitted from the object itself is picked up. Therefore, a human body detecting means CL4 detects a human body distinguishing a high-radiation low-temperature object (human body) from among low- radiation high-temperature objects (background) based on the above-mentioned fact.

IPC: F01N1/10
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To improve space efficiency and noise eliminating efficiency by forming, of a porous material, a bottomed tubular main body part and an installing part for fixing the main body part to a pneumatic apparatus. SOLUTION: A muffler 1 consists of a tubular main body part 1a and an installing part 1b, and is formed by pressurizing a porous material such as, for example, sintered metal, sintered resin, and the like. Fine exhaust holes made of a porous material are formed on the installing part 1b besides the main body 1a. Since the main body 1a and the installing part 1b are formed of a noise eliminating raw material such as the porous material in the muffler 1, and since the exhaust holes are formed around the whole of the muffler 1, a flow rate of air can be increased with a high porosity, and noise eliminating effect can be obtained at all positions. It is thus possible to improve space efficiency and noise eliminating efficiency.

IPC: B23K15/00
Filed: 1990-11-15
Abstract: PURPOSE:To prevent a crack of a weld zone and to improve conductivity by inserting a ringlike filler metal into an abut part of materials to be welded made of Al parts, welding these with a high density energy beam and regulating composition of the weld zone in the specified range. CONSTITUTION:An Al pipe 7 and Al terminal metal 8 are machined so that these can be abutted on each other and the ringlike filler metal 13 is inserted thereinto according to the molten metal quantity. In order to prevent an electron beam 12 from being diffused, a vacuum is formed and the materials to be welded are rotated by a rotating jig and the electron beam 12 is converged by a converging coil 10 and as necessary, the electron beam is oscillated by a deflecting coil 11 to obtain a weld bead 9. Since electron beam welding is performed by high density energy, the weld bead width can be narrowed and a resistance value of a weld bead part can be reduced. The composition of the final weld zone is regulated in the range of 0.45-5.35% Si and 0.15-0.87% Mg. Consequently, the crack of the weld zone can be prevented and the conductivity can be improved.

IPC: A01G33/02
Filed: 1993-11-15
Abstract: PURPOSE:To enable control of red rot fungi in a lower concentration and in a shorter time independently of the sea water temperature over the whole fishing season by treating a laver culture net with an acid treatment solution having a temperature higher by a specified degree or more than the water temperature in the circumferential sea area. CONSTITUTION:The degree of increase in the concentration or extension of the immersion time can be reduced by treating a laver culture net with an acid treatment solution having a temperature 5 deg.C or more higher than the water temperature in the circumferential sea area. Further, if the temperature of the acid treatment solution is kept to a constant value at least 5 deg.C higher than the water temperature in the circumfential sea area, the treatment can be carried out in the same concentration and in the same period over the whole fishing season. Furthermore, both the treatment period and the consumption of the treatment solution can be further reduced according as the preset temperature is raised. In addition, in the case of an immersion treatment of a laver culture net, more unified treatments can be carried out, e.g. by keeping the pH value to a constant value within the range of 1.5 to 3.0. The application of this treatment solution can be carried out by immersing a laver net in the treatment solution accommodated in a treatment tank and kept to a constant temperature and a constant pH as mentioned above or by spraying it thereon.
