Title: Sensitivity calibration method for magnetic flaw detection device
Inventor: NAKAMURA ETSUHISA
IPC: G01N27/83
Filed: 1988-10-01
Abstract: PURPOSE:To easily and accurately calibrate sensitivity when a thin sheet steel is fed by providing a magnetism sensing element group, a frequency filter, and an absolute value circuit. CONSTITUTION:A detection head 2 is equipped with a fluid flotation type follow-up mechanism which incorporates the magnetism sensing element group 1 on the top surface side of a material S to be inspected. Then when the material S to be inspected is magnetized by an electromagnet 3, leak magnetism of intensity proportional to the surface roughness of the material S to be inspected is generated. Further, the leak magnetism detected by the element group 1 is converted into an electric signal, which is amplified 4 and passed through the frequency filter 5 to remove its noises. Then the signal passing through the filter 5 enters the absolute value circuit 7 through an attenuator 6 to obtain the absolute value of the signal voltage. A sample holding circuit 8 at a following stage samples the input signal for a constant time to hold the peak value within the sampling time and the peak value is read in a computer 9 the sampling time later.

Title: Forming method of insulating film
Inventor: YASUDA NAOKI
IPC: H01L21/316
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To make the distribution of total of structure strain and internal strain uniform in the thickness direction of an insulating film, by controlling the thermal load which is applied to the insulating film at the time of forming it, making the internal strain small from the substrate side toward the opposite side, and controlling the internal strain. SOLUTION: When an SiO2 film having uniform strain distribution in the film thickness direction is formed on a silicon substrate 12, the temperature of a vessel 11 is rapidly decreased. Thereby, the SiO2 film can be formed under the temperature condition that the strain distribution of an already formed SiO2 film is scarcely changed by the temperature when a new SiO2 film is formed. The temperature for forming the SiO2 film is so controlled that the Si-O-Si absorption peak wave number of an SiO2 film of the uppermost surface which is newly being formed has always a constant value. Thereby, an SiO2 film wherein the distribution of tatal of structure strain and internal strain is uniform in the film thickness direction can be obtained.

Abstract: PURPOSE:To use a low speed clock by dividing an input into two, the upper and lower bit sides, integrating a group of a small bit number by a single current source, and integrating the other group for a reference time by using a current source selected from plural current sources. CONSTITUTION:A data DH of the upper 6-bit is preset to a high-rank counter 32a, and a data DL of the lower 10-bit is loaded to a low-rank latching circuit 34a. In accordance with ''1'' in the data DL, a current source 2<2>i0 is connected to an integral line L1 by a control signal M3. When a converting instruction comes, switches SW1, SW31 and SW32 are controlled by control signals S1, S31 and S32, respectively, and an integral operation is started, and simultaneously, down- counting of the counter 32a is started. The control signal S32 switches the switch SW32 to an input terminal T1 side only for one period of a clock signal phi, therefore, the switch SW32 is switched to a ground side when one period is ended, and an integration of the lower 10-bit is ended. Thereafter, when the counter 32a becomes all bit ''0'', the switch SW31 is switched to a ground side, and an integration of the upper 6-bit is ended.

Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To read and record an image recorded on a film efficiently without waste by reading the image from an image recording area at a read position, recording the image on other recording medium and writing information denoting a fact of recorded data on an information recording area corresponding to the image recording area recording the image when the image recording section records the image. SOLUTION: Windup of a film is started and IX information is read from an information recording area sequentially as to all frames while making windup and the read IX information is stored in a memory 11a of a control section 11. When the IX information of the final frame is read and windup is finished, a place corresponding to a frame next to the final frame is placed at a read position. The IX information of the one-preceding frame to the frame at the read position is read from the memory 11a and whether or not the frame is recorded is discriminated from a flag. When no image is recorded on a frame, the film is rewound by one frame and the unrecorded frame is moved to the read position.

Title: Formation of forged product with groove
Inventor: MORITA MORIHARU
IPC: B21J13/02
Filed: 1993-10-04
Abstract: PURPOSE:To obtain a high precision forged product with groove by giving inclinations gradually protruding on the inner surfaces parallel to ribs for forming the grooves arranged in a cavity and forming with dies having split type structure divided with the parallel surface to the ribs. CONSTITUTION:At the time of pushing in a blank 9 with a punch 8, both ends of the blank 9 are abutted on the inclining surfaces of a cavity and plastically deformed. On the way of this deformation, the flow of the blank 9 widened over the bottom surface, is blocked by the penetration of the ribs, and stress P1 is concentrically acted in the inner surfaces of the ribs. However, as the die 1 is divided by the parallel surface to the ribs, the closeness of the divided surface 4 is weakened to absorb the stress P1. On the other hand, both side surfaces of the blank 9 are gathered to the inside along the side surfaces, and a stress P2 is allowed to act on the ribs to keep the balance with the stress P1. These stresses P1, P2 can be adjusted by the inclining angle of both side surfaces and the length of the blank 9, etc.
