IPC: G01D9/30
Filed: 1988-02-04
Abstract: PURPOSE:To hold a recording pen by selectively raising the recording pen, by relatively simple constitution such that a measuring signal or a pen raising position signal is applied to a servo mechanism by a change-over switch to be displayed. CONSTITUTION:A measured value is recorded by the recording pen 6 driven by a servo mechanism 5.

After that the existence of inclusion layer 3 is detected by a surface defect inspection method. In this case, since nondeleterious nonmetallic inclusions 4 does not open, they will not appear as a defect in the surface defect inspection method. Then the opening and its vicinity are shaved with grinder, etc., and a hole is bored. Then the bore 6 is filled by welding to mend and then butt weld is performed.

Title: Adhesive tape
Inventor: SUZUKI YUKIO
IPC: C09J7/02
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an adhesive tape wherein force is scattered over the entire tape width when a large winding pressure is applied and wherein the adhesive is fixed in the depressed part to prevent weaving. SOLUTION: In an adhesive tape partially having a region A wherein an adhesive is arranged in the width direction on the surface of a tape base, a depressed part is formed on one or both sides of the base within the adhesive- coated region A. Preferably, the depth (a) of the depressed part is from 0.1 to 1.2 times as large as the thickness (b) of the adhesive layer. This allows the force to be scattered over the entire width of the tape when a large winding pressure is applied, and also strongly inhibits weaving since the adhesive is fixed at the depressed part. Therefore, shear in the rolled form is inhibited when the tension applied to the tape grows larger as the application rate grows faster or when the tape is under storage. Furthermore, even when the rolled-up length of the tape is long, an extremely stable product which allows little weaving, is obtained.

Abstract: PURPOSE:To manufacture a cabinet and mold itself easily and inexpensively, by performing molding by casting molten synthetic resin through only one point of a film gate communicating with a cavity part which is on the opposite side of the cavity part forming unpresentable surface of a molded article. CONSTITUTION:A runner 2, gate 3 and cavity 4 communicating with a sprue 1 are formed by a stationary mold 5 and movable mold 6. Further, the runner 2 and its gate 3 are a piece each and that the gate 3 is a film gate. When synthetic resin 11 with which a foaming agent 10 has been mixed is injected under a molten state and the molten resin is cast into the cavity 4 from the center of a cavity part 4a through the sprue 1, runner 2 and gate 3, a front cabinet 7 is molded. As the molten resin is cast through only one point of the gate 3, a weld line 12 becomes only the one point of the center of the cavity part and creases A are hardly generated as the gate 3 is the film gate because the flowability of the molten resin is favorable.

Title: Reduction of production in coke oven
Inventor: MIZUNO YUTAKA
IPC: C10B57/00
Filed: 1978-03-06
Abstract: PURPOSE: To enable a substantial reduction of production in a coke oven without lowering the quality of coke or damaging the apparatuses, by charging coal to the upper empty space of the coke oven generated by the volume contraction caused by the carbonization of initially charged coal, and continuing the carbonization of the coal.  
     CONSTITUTION: Carbonization of coal is carried out at a lower oven temperature for a longer carbonization time. The produced coke is left in the coke oven as it is, and the upper empty space of the coke oven generated by the volume contraction of coal during the carbonization, is filled with fresh coal. After a proper time from the end of the carbonizaion of the newly charged coal, the produced coke is discharged from the coke oven.  
     EFFECT: The first carbonized coke is held in the oven for a very long period, which results in a substantial reduction of production. The leak of air into the coke oven is prevented by the internal pressure generated by the gas produced by the carbonization of coal, and the combustion and falling-off of the oven wall made of car bonaceous material can also be prevented.
