Title: Reed valve structure
Inventor: FURUHASHI MASARU
IPC: F02B33/30
Filed: 1985-10-22
Abstract: PURPOSE:To make it possible to smoothly change the flow rate of air, by providing such an arrangement that at least one of the shapes of both valve holes or the relative positions of the valve holes for both valve elements is different from each other while both valve elements have the same shape. CONSTITUTION:A valve hole 19 is composed of a pair of a rectangular valve holes 19a, 19b, and reed valve elements 20 are arranged at both valve holes 19a, 19b, having the same shape and made of the same material. One valve hole 19a among the holes 19a, 19b has a larger opening area while the other valve hole 19b has a smaller opening area. During the rotational speed of an engine being increased or decreased, the resonance of the individual reed valve elements 20 causes the timings of drops of mixtures F passing respectively through the valve holes 19a, 19b to be shifted from each other, and therefore, it is possible to moderately change the flow rate of the mixture F through the entire valve hole 19.

Title: Sodium leakage detector
Inventor: HARA JOJI
IPC: G21C17/025
Filed: 1985-10-24
Abstract: PURPOSE:To isolate a sodium leakage detector from a primary system completely and to improve safety, by inserting a water capsule, which jets a cleaning agent for removing sodium attached on the surface of the disc of a solenoid valve, into the solenoid valve. CONSTITUTION:In a water capsule 18, water 19 and inactive gas 20 (e.g., nitrogen or argon) are compressed. A thread 21 is provided on a protruded part. A cut part 22 is provided at the tip part. The capsule is inserted in the main body of a solenoid valve with the thread 21. When sodium leakage is detected, a disc 6 of an inlet solenoid valve 5A is lowered and the valve is closed; the cut part 22 of the tip part of the water capsule 18 is pushed with the disk 6 and broken down. The water 19 is jetted by the pressure of the inactive gas 20 and reacted with attached sodium 16 at the surface of the disk 6. Thus sodium hydroxide 16 is washed away. Then, the inlet solenoid valve 5A is completely closed. Therefore, the sodium leakage detector is completely isolated from the primary system.

Abstract: PROBLEM TO BE SOLVED: To save a space by shortening the total length of a manufacturing line by a method wherein a pallet stacked body in a heating furnace is enabled to stay in a stop state in the furnace until the following pallet stacked body is piled up. SOLUTION: In a manufacturing part 2, a heating furnace 6 and a cooling furnace 7 which are arranged to a downstream side from a tile transloading position P of a pallet transfer conveyor 4, a pallet piling up/unloading apparatus 8 and 8a which are arranged to upper and downstream sides thereof, and a tile unit-peeling transferring apparatus 9 or the like which are arranged to their downstream side, are provided. A pallet stacked body which is piled up by the pallet piling up apparatus 8 contained in the heating furnace 6 is made in a stop state in the furnace until the following stacked body is piled up with the pallet piling up apparatus 8. Since a tile connected material can be heated for a specific curing time thereby though a length of the heating furnace 6 is shortened, a space can be saved by narrowing an installing area of a tile unit-manufacturing line 1.

Title: Strainer
Inventor: UESUGI KATSUHIDE
IPC: B01D35/02
Filed: 1983-12-15
Abstract: PURPOSE:To prevent breakage of a filter screen due to vibration of the filter screen and to reduce pressure drop of a strainer itself to a small value by reducing vibration of the filter sceen effectively. CONSTITUTION:Reduction of vibration and pressure drop of a filter screen 36 is attained by using a screen 35, 37 having coarser meshes. Namely, a screen 37 having high vibration resistance and coarse mesh is provided to the upstream side of a flow and a screen 35 having high vibration resistance and coarse mesh aiming reduction of pressure drop is provided to the downstream side of the filter screen 36. By using these three screens as one set as if they were a sheet of screen, the vibration of the screen 36 installed to the midway of the three screens is effectively reduced. As the result, two contradictory objects, i.e. filtration of foreign matters as an original object of the screen, and reduction of vibration, are achieved simultaneously.

Title: Drive circuit for inductive load-to- current conversion
Inventor: CHIYAARUZU SHII OOSUCHIN
IPC: H02P6/08
Filed: 1992-09-07
Abstract: PURPOSE: To form a transconductance amplifier loop being employed as a pull- down driver circuit by coupling an operational amplifier with a variable gain amplifier. CONSTITUTION: Resistors R1 , R2 determine the gain of an amplifier A4 designed to be stabilized at unit gain and having a relatively wide frequency response. Main loop correction is effected by a capacitor Cp and a resistor R3 . These components provide a low frequency pole and the loop gain is decreased to that prevailing prior to phase conversion of 180 deg.. When the components of R3 and Cp are employed, effective loop correction can be effected regardless of the characteristics of a transistor M1 , a load inductor L1 , and the amplifiers A4 , A1 . When the loop is closed, a transient voltage caused by fluctuation of the load current can be minimized by regulating the variation rate of an input voltage VIN.

Title: Laser welding method for metallic plate, and structural body
Inventor: MINAMIDA KATSUHIRO
IPC: B23K26/21
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To reduce thermal distortion and prevent deterioration in strength of a weld part and accuracy of a structural body by spot-welding two metallic plates in a way to form a plurality of nuggets while the ratio of nugget diameter and pitch along a closed curve is a given value or more. SOLUTION: The ratio of nugget diameter/pitch is made to be 0.5 or more. A nugget is formed along the closed curve, so that surging fracture can be avoided because of large load resistance per point. For example, when diameter of the nugget is 0.5 mm and the number of nuggets is 24 respectively, pitch of the nuggets gets smaller as the diameter of the circle gets smaller from 6 mm, to 4 mm, 3 mm and 2 mm. The pitch is less than 1/2 of the nugget diameter, and if the pitch exceeds 1/2 of the diameter, enough strength can not be obtained. Spot welding is performed in a manner that the nuggets are disposed along a straight or curve line, and also spot welding may be performed in a manner to include a straight or curve line within a closed curve. A nugget group along the closed curve reinforces strength of the straight or curve line nugget group.
