Title: Reducing valve with relief valve
Inventor: FUKUDA MITSUYUKI
IPC: G05D16/06
Filed: 1986-12-02
Abstract: PURPOSE:To compactly form constitution by constituting a reducing valve mechanism which open/close-controls communication between a primary side and a secondary side with a cylindrical valve and a valve sheet, and providing a relief valve mechanism at connecting part between the cylindrical valve and a pressure sensitive plate. CONSTITUTION:By lowering the pressure sensitive plate 2 when pressure at the secondary side Y is lowered less than set pressure, the cylindrical valve 30 is moved downward by a connecting member (b) operated by the pressure sensitive plate 2, and is separated from the valve sheet 31, and the reducing valve mechanism 3 is placed under a valve opening state. Thereby, pressure at the primary side X is sent to the secondary side Y. Next, the mechanism 3 is in a valve closing state, the pressure sensitive plate 2 is raised when the pressure at the secondary side Y increases abnormally, however, the valve 30 is abutted with the sheet 31, then, it is prevented from being raised upward, therefore, a valve seat 61 in the bypass valve mechanism 6 is separated from a bypass valve 60 provided at the member (b), and the valve 6 is placed under the valve opening state. In such way, the pressure at the secondary side Y is exhausted from an exhaustion opening (a) to the outside via a bypass valve opening 62. By constituting a device in such way, it is possible to form the constitution compactly since no balancing valve is used for the opening/closing of the bypass valve.

Abstract: PURPOSE: To achieve cost reduction of production of a metallic compression binder for connecting tubes of polymeric materials by covering a flange portion of a supporting sleeve with the compression binder where a tubular joint is integrally formed at one end of the tube, connected to the supporting sleeve, and fastened by the compression binder. CONSTITUTION: When a pipe or tube 4 is connected to a supporting sleeve 2 with a plurality of annular ribs 21 and a relatively large diameter flange 22, the tubular joint 41 integrally formed on the end of the tube 4 is pushed on until it strikes the flange 22, and the compression binder 3 is fastened on the tubular joint 41 with a press tool. Here, the ribs 21 bite the inner surface portion of the tubular joint 41 to securely fasten the tubular joint 41 liquid-tight on the support sleeve 2.

Abstract: PURPOSE:To enable a bending part to flex easier than the other part by providing a bending part in at least one part in a single parison of at least two layers formed of soft/hard sythetic resin layers, and increasing thickness ratio of the soft resin layer higher relating to the hard resin layer in the bending part. CONSTITUTION:An automobile air conditioning duct pipe B, in which a bellows part J in an intermediate part and a joint part T with screw streak groove R in one end part are provided, is formed by blow molding a single parison of two layers of soft/hard synthetic resin layers F, G. Here in a total unit of the duct pipe B, thickness ratio of the hard synthetic resin layer G is highly set except parts of the bellow part J and the joint part T. On the other hand, thickness ratio of the soft synthetic resin layer F is highly set relating to the hard synthetic resin layer G in the parts of the bellow part J and joint part T. Thus in the case of arranging the pipe three-dimensionally built displacing the center at assembly time, a bending part is made easily bent to facilitate its mounting.

Abstract: PURPOSE:To correct a picture defect or a sensitivity uneveness by varying the timing of a reading pulse corresponding to the displacing amount of the picture unit of a displayed optical image. CONSTITUTION:A solid image pickup element 2 converts the optical image in which picture elements are arrayed in a horizontal direction and a vertical direction into an electric signal. And also, an optical displacing means 9 is arranged on an optical axis between the image pickup element 2 and an object, and the optical image to be image-formed by the element 2 is displayed in a horizontal picture element direction and a vertical picture element direction to the element 2. At that time, the displacing amount of the optical image displaced by the displacing means 9 is detected by a means 10 which detects the displacing amount, and a timing generating means 5 generates the read pulse for reading the electric signal from the element 2. Then, a control means 7 varies the timing of the read pulse generated by the timing generating circuit 5 corresponding to the displacing amount of the picture unit of the optical image displaced by the displacing means 9.

Title: Overcurrent interrupter for feeder line
Inventor: SAEKI MITSUO
IPC: H02H3/093
Filed: 1994-11-22
Abstract: PURPOSE: To reduce power loss by providing the feeder line for a load with a switch circuit being turned OFF immediately upon detection of an overcurrent flowing through the feeder line to interrupt the overcurrent. CONSTITUTION: Power is fed from a power supply 2 through a feeder line 3, a switch circuit 4 and a current detecting section 5 to a load 6. Current flowing on the feeder line 3 is detected at the current detecting section 5 in the form of a voltage value and delivered to a control section 1. When the input current value is higher than a set current value and sustains for a set time or longer, a decision is made that an overcurrent is flowing on the feeder line and a switch control section 11 is fed with a command for turning a switch OFF. Since an overcurrent is detected quickly and the feeder line 3 is interrupted accurately with high speed, power is not wasted and the service life of a battery, being used as a power supply 2, can be prolonged.

IPC: B04C9/00
Filed: 1989-11-07
Abstract: PURPOSE:To prevent the degradation in quality by providing a discharge route for the dusty gas which leaks from a labyrinth seal and passes the route separately from a discharge route for the dusty gas after the passage via a rotor. CONSTITUTION:The route B for the dusty gas passing the labyrinth seal 120 is provided in addition to the route A for the dusty gas passing the vanes 110a of the rotor 110 of the classifying device 100 on the inner side of the labyrinth seal 120.

The powder captured by the cyclone 400 is separately recovered and is used for other applications. The negative pressure of the route B is kept higher than the negative pressure of the route A in a microspacing 130, by which the back flow of the dusty gas to the route B is prevented. The product quality is stabilized in this way.

Title: Manufacture of semiconductor element
Inventor: TACHIBANA KOJI
IPC: H01L21/223
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor element which can accurately control an impurity diffusion concentration to form a shallow impurity diffusion layer accurately and stably. SOLUTION: A wafer W2 in which impurities such as phosphorus are previously diffused, is positioned close to a wafer W1 having a non-diffusion region processed with an oxide film 2 as a mask as opposed at their faces to each other, and then subjected to a high temperature annealing treatment in an atmosphere of N2 at 850 deg.C. This causes impurities in the wafer W2 to be outdiffused and thermally diffused into a diffusion region of the wafer W1, thus forming an impurity diffusion region.  In this case the depth and concentration of the impurity diffusion layer to be formed in the wafer W1 can be accurately controlled by the concentration of impurities diffused in the wafer W2 and by the temperature and time of the high temperature annealing treatment to thereby form a shallow impurity diffusion layer of a thickness of 0.47 μm or less in the wafer W1 accurately with a target impurity concentration.

Title: Incense stick
Inventor: KIKAWA TAKEO
IPC: A61K8/00
Filed: 1989-11-07
Abstract: PURPOSE:To obtain the subject incense stick capable of readier ignition in a shortened time required therefor by forming one end side of the incense stick into a tapered shape. CONSTITUTION:One or both ends sides of an incense stick in the longitudinal direction are formed into a tapered shape by gradually reducing the cross section area according as going towards the top part in comparison with that of other most cross section. In the tapered-shape part, the ratio of the surface area to the volume is enlarged. Because of the above-mentioned higher surface area ratio, the amount of heat absorbed per volume at the time of ignition and the air supply to the combustion part increase relatively at the same time and the time required for ignition and combustion is reduced therefor.
