Title: Decarburization-preventive heating method for steel rolling process
Inventor: MURAKAMI MASAAKI
IPC: C21D1/52
Filed: 1981-03-23
Abstract: PURPOSE:To effectively prevent the decarburization in rolling process of steel materials by operating a heating furnace in such a way that the residence time of steel materials in the heating furnace until the time when the surface temperature of the steel materials to be heated attains a specific temperature amounts in a specific per cent in the whole residence time. CONSTITUTION:In the operation of a heating furnace in the rolling process of steel materials, the residence time of steel materials to be heated in the furnace until time when the surface temperature of the steel materials attains 650 deg.C is set up so that it amounts 80-90% of the whole residence time. Thus, the ferrite decarburization in the steel materials to be heated can be prevented and the total decarburization depth and the amount of scale formed can therefore be greatly improved.

Title: Method of inspecting external appearance and apparatus thereof
Inventor: TANABE YOSHIKAZU
IPC: G03F1/00
Filed: 1988-02-26
Abstract: PURPOSE:To accurately evaluate the hole pattern of a high aspect ratio without increasing the scale more than required by irradiating an exciting light to a thin film formed in a predetermined pattern on a substrate, forming an image to be observed on the basis of fluorescence generated from the position of the film irradiated by the light, and detecting the fluorescence generated from the film. CONSTITUTION:A substrate 2 such as a semiconductor wafer covered with a photoresist layer 5 formed in a predetermined hole pattern is placed on a sample base 1. The focus position of an objective lens 6 of a region to be observed of a hole pattern 4 formed on the layer 5 of the base 1 is adjusted. An exciting light 8 in which only a predetermined wavelength is selected is incident through a dichromatic mirror 7 and the lens 6 to a predetermined region on the substrate 2. The layer 5 generates fluorescence 8a having a longer wavelength with the light 8, transmitted together with the partial light 8 reflected on the substrate 2 through the mirror 7, and selectively absorbed to an absorption filter 17. Accordingly, only the fluorescence 8a is incident to a camera 16 to be detected.

Title: Electrode structure
Inventor: MORI SHIRO
IPC: B29L31/34
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To significantly reduce soldering places, and decrease manufacturing man-hours so as to manufacture at low costs by coupling plural terminals at a coupling portion, and integrally molding to delete a coupling portion. SOLUTION: Before molding terminal plates, the terminal portions of a positive pole terminal 7, a negative pole terminal 8, and a T-pole terminal 9 are pressed into U-shapes, and other portions have been pressed at bending positions, in advance. The pressed terminal plates are fitted into predetermined positions using a forming die and fused resin is injected into the die, so that the positive pole terminal 7, the negative pole terminal 8, and the T-pole terminal 9 are integrally molded by a resin mold 25. Thereafter, coupling portions 5, 6 are punched by pressing so that the positive pole terminal 7, the negative pole terminal 8, and the T-pole terminal 9 are separated to be independent.  Although the T-pole terminal 9 does not pass through the mold 25, its bending portion formed into a U-shape bites into the rear face of the mold 25, so that the same is not allowed to fall out of the mold 25, even if the coupling portion 6 is deleted.

Title: Abnormality detecting method at press fitting in press fitting machine
Inventor: SATOU MOTOHIRO
IPC: G01N29/04
Filed: 1978-04-12
Abstract: PURPOSE: To distinctly judge the abnormal state in press fitting without being affected by indefinite criteria such as visual osbervation, hearing sounds, etc. and environments as usual by mounting an AE detector to the press fitting machine and directly detecting only the acoustic signal generated at the press fitting.  
     CONSTITUTION: After other member 3 is set to one member 2 which is temporally placed on the table 1c of a press fitting machine, the piston 1b which is operated by the hydraulic pressure of a cylinder 1a is lowered to press fit the other member 3 onto one member 2. An AE detector 4 is mounted by means of, e.g., adhesive agents or the like, to the portion which does not hinder the press fitting work, on the side face of the abovementioned piston 1b and only the acoustic signal generated with abnormaly is normally detected a the time of press fitting work. The acoustic signal having been detected is amplified with a preamplifier 5 and the signal is filtered with a filter 6. The filtered signal is further amplified with a main amplifier 7 and is then subjected to judgement of abnormality by a judgement circuit 8.

Abstract: PURPOSE:To accurately execute a dropping voltage display of an electric source and an initialization of an electronic equipment by detecting every constant time whether an input voltage exceeds a specified voltage or not and comparing the number of times exceeding the specified voltage with a standard value. CONSTITUTION:On detecting the input voltage every constant time by an input voltage detecting means 2, the number of times exceeding the specified voltage and the number of times under the specified voltage are added by first, second addition means 3a, 3b and stored in first, second storage means 4a, 4b for number of times respectively. By using a deciding means 5 for the detecting number of times, a detection and counting-storage are repeated until the sum of the stored number of times which are over and under the specified voltage come up to the detecting number of times set previously. And, when coming up to the detecting number of times, the stored number of times are brought into the initialization by an initialization means 8 and an action is continued repeatedly. Whenever the set detecting number of times have been worked out, the number of times which are under or over the specified voltage are compared with a value set in first and second deciding means 7a, 7b and decided. And, based on its result, outputs A, B for the initialization of the electronic equipment or the dropping voltage display are outputted.

Title: Crater treatment method in plasma keyhole welding
Inventor: HORI JIYUNJI
IPC: B23K10/00
Filed: 1979-04-10
Abstract: PURPOSE: To prevent the formation of keyholes and recesses by resetting plasma gas flow to the flow at the welding with a delay by the time when the molten metal of crater part solidifies after the arc has been cut off.  
     CONSTITUTION: When a welding torch 6 stops, the refilling of the crater part is begun. First, welding current is gradually decreased through slope-down controlling, and at the same time an on-off valve 2 is closed to reduce plasma gas flow d 1 + d 2  to d 1 . Thereby, the keyhole of the crater part is perfectly embedded by the molten metal. Thence, the on-off valve 2 is opened with a delay by the time T 2  when the molten metal in the crater part solidifies perfectly after slope-down time T 1  of the welding current ends and the arc is cut off, so that the plasma gas flow is reset to the original flow at the welding. Hence, blowing away of the molten metal by the overshooting at the resetting no longer occurs.
