Title: Method and apparatus for evaluating characteristic of semiconductor ion sensor
Inventor: SAITO ATSUSHI
IPC: G01N27/414
Filed: 1989-01-18
Abstract: PURPOSE:To enable evaluation of a characteristic without impairing an ion- sensitive film and an enzyme fixation film and without being in contact with other disposed components by impressing a voltage through a gel containing an electrolyte solution and provided on an element. CONSTITUTION:A gel 3 which contains an electrolyte solution and can gelate easily is formed on a sensitive element of a semiconductor ion sensor 2, and a gate voltage is impressed through this gel 3. When calcium alginate is used as the gel 3, for instance, a 1% sodium alginate solution is dripped down from a nozzle 6a onto the respective ion-sensitive elements of a plurality of semiconductor ion sensors 2 provided on a substrate 1 and then a 0.1M calcium chloride solution is dripped thereon from a nozzle 6b, for gelating. A probe 4 is brought into contact with an electrode part and probe 5 with a gel part, respectively, and the characteristic of each semiconductor ion sensor is measured by impression of a voltage.

Title: Direct current oil impregnated power cable
Inventor: IINUMA KOICHI
IPC: H01B3/52
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a de-oiling void due to temperature change or the like and perform impregnation of insulation oil during cable manufacturing quickly by impregnating insulation soil with high viscosity having a specific dynamic viscosity primary containing polybutene in insulation paper wound around a conductor. SOLUTION: Insulation oil with high viscosity impregnated in an oil insulation body primary contains polybutene and has dynamic viscosity of 25,000 to 40,000cst at 40 deg.C and 600 to 1,000cst at 100 deg.C. Therefore, in a cable normal temperature range of 20 to 60 deg.C, since dynamic viscosity is high, a de-oiling void is hardly generated at a heat cycle, and since dynamic viscosity is low at nearly 100 deg.C, time of impregnation process during cable manufacturing is short. Polybutene of about 800 to 1,500 in average molecular weight is preferred, and dynamic viscosity is adjusted by addition thereto high-viscosity mineral oil, naphthene-based or paraffin-based synthetic oil, rubber such as polyisobuthylene or butadiene or the like. Use of insulation oil with different dynamic viscosity depending upon see water temperature or difference in elevation of a laid route is preferred.

Title: Intake air flow rate control device of engine
Inventor: MINEGISHI TERUHIKO
IPC: F02M35/10
Filed: 1990-01-20
Abstract: PURPOSE:To maintain measuring accuracy of a flow rate control valve for a long period by installing a means provided with a function to catch particles, such as carbon included in the spitting gas from an engine at a downstream position remoter than intake flow rate control valve on the way of a by-pass passage. CONSTITUTION:When spitting gas enters into a by-pass passage 9, the spitting gas flows in the second pipe body 9B, a trap 18, and the first pipe body 9A in the passage line 9' on the downstream of a flow rate control valve 10. During this flow process, the pipe body 9B and a trap inner wall 18' face each other through a very small clearance 21, so that gas which flows out of the pipe body 9B increases its flow speed by the throttling action of the clearance 21, collides with the trap inner wall 18', and its flow direction suddenly changes to an opening edge 19 side of the pipe body 9A side. Due to the collision and the flow speed changes, heavy particles, such as carbon adhere to the trap inner wall 18' by inertia, accumulating inside the trap. As a result, foreign materials do not adhere between a measuring valve part 11a and a valve seat 14a.

Abstract: PURPOSE:To obtain a spectacle frame which is light-weight and has sufficient mechanical strength and corrosion resistance, by coating a Cu single substance or a Cu alloy around a Ti single substance or a Ti alloy to form a wire rod and producing individual parts with a wire rod produced by cladding this wire rod and soldering them in one place at least. CONSTITUTION:For example, a columnar pure Ti having 50mmphi diameter and 1,000mm length is coated with a Cu alloy having 51.25mmphi outside diameter, 50mmphi inside diameter, and 1,000mm length, and they are extruded at 600 deg.C by the hot hydrostatic pressure extrusion method to form a composite wire having 10mmphi diameter. The composite wire is subjected to wire drawing repeatedly by annealing (600 deg.C) and cold working to form a blank wire having 2.6mmphi diameter. Since the surface of a blank wire 10 formed in this manner consists of the Cu alloy 3, this blank wire 10 has an excellent soldering property; and the blank wire 10 is used to form individual parts (temples 11, rims 13, a bridge 15, hinges 17, and pad arms 19) of the spectacle fame. Next, individual parts are joined by soldering.

Filed: 1978-02-06
Abstract: PURPOSE: To prevent leakage of untreated waste gas by directing the total amount  of a waste gas from a waste gas source into a branch duct together with a portion of treated waste gas recirculated through a direct connection duct.  
     CONSTITUTION: A direct connection duct 3, which connects between a waste gas source and a discharge system 2 directly, is fitted the rein with a flange-like baffle 13. The duct between the source and a divergent point of the direct duct 3 and a branch duct 4 is fitted with a plate-like baffle 12 and a ridge-like rectifier structure 8. In normal operation, the waste gas from the source cannot flow directly through the duct 3 to the discharge system 2. The total amount of the waste gas from the source is directed into a branch duct 4 together with a portion of the treated waste gas recirculated through the direct duct 3. Thus the leak-in of untreated waste gas can be avoided.
