Abstract: PURPOSE:To conduct a diversity of tests by varying properly at least one of the flow velocity and flow rate of a heat medium which is injected and supplied to a body to be inspected from a nozzle. CONSTITUTION:The opening extents of the stop valve 11a of main piping 6 and the stop valve 11c of a reflux pipe 11b are set properly to prescribed values and semiconductor devices 5 are mounted on test tables 4.

Abstract: PURPOSE:To prevent broken wire failure from occurring by overlaying a Mylar film material on a sealing cover for covering the outer periphery of a semiconductor element and fixing the sealing cover to a substrate with adhesion of the Mylar film material. CONSTITUTION:A semiconductor element 1 is fixed on a surface 3A of a substrate 3, and a sealing cover 5 made of synthetic resin is put over the element 1 packaged on the substrate 3 by a method wherein a pad 4 of the substrate 3 and a terminal part 2 of the element 1 are bonded to each other with a wiring material 12.

Title: Thin-film magnetic head and its production
Inventor: YAMAMOTO TOMOKI
IPC: G11B5/31
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a defectless protective layer by forming bump layers by flaring their peripheral surfaces near to terminal layers. SOLUTION: This thin-film magnetic head is constituted by forming the terminal layers 14 via insulating layers 2 on a substrate 1, forming the bump layers 15 in superposition on the terminal layers 14 and exposing and forming the protective layers 16 on their surfaces. The bump layers 15 consist of the skirt surfaces R of which the outer peripheral surfaces in contact with the protective layers 16 flare near to the terminal layers 14 from the exposed parts and the peripheral groove surfaces T recessed from the end side on the terminal layer 14 side of the skirt surfaces R toward the central parts of the bump layers 15.  The outer peripheral surfaces of the bump layers 15 are flaring skirt surfaces R and, therefore, the interlacing of the growth directions of the protective layers 16 does not arise at the time of forming the protective layers 16 covering the bump layers 15 in the production stage of the thin-film magnetic head. The defectless protective layers 16 are thus formed.

On the other hand, the properties and state of exhaust gas are measured by each of oxygen concentration sensors 8, 9 in both exhaust pipes 5, 7 before and behind a catalyst 6. The results of measurements are severally inputted into a control device 10 to control the internal combustion engine 4. For example, an air-fuel ratio feedback control means 11 computes the fuel injection pulse of an injector to control the air-fuel ratio of the internal combustion engine 4. In this case, a leakage detecting means 20 detects leakage in an exhaust system based on the outputs of the oxygen concentration sensors 8, 9.

Title: Soldered state inspection device
Inventor: SHIGEYAMA NAOKI
IPC: G01B11/24
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To accurately inspect the soldered state of a lead by clearly judging the end face of the lead. SOLUTION: A light projecting section 11 projects slit light, which is parallel to the Z-axis upon a lead 1a and solder in the X-Z plane. Another light projecting section 12 projects slit light upon the lead 1a and solder obliquely to the Z-axis in the X-Z plane. Since the slit light 12a is also projected upon the end face of the lead 1a, reflected light is also produced from the end face of the lead 1a. Therefore, the position of the end face of the lead 1a clearly appears in the picture data taken with an image pickup device 14 which is obliquely set against the Z-axis in the X-Y plane. Therefore, the soldered state of the lead 1a can be inspected accurately.
