Filed: 1981-12-07
Abstract: PURPOSE:To allow the detection of the yield in a halfway process, by providing a region having the width approx. the same as that of an emitter region of the element part in a lattice form on a check pattern. CONSTITUTION:An emitter aperture part in a lattice form is immediately under a polycrystalline Si 60, and the emitter width is the same as that of the element part. In other words, an insulation oxide film 40 is formed on a substrate 10 having the base region 30, and, at the same time as the formation of emitter aperture, an aperture is applied on the check pattern part. Thereat, the width of the aperture of the check pattern part is designed the same width as the emitter aperture of the element part and formed in a lattice form. The probe for measurement can be contacted on a polycrystalline Si layer 60. With the polycrystalline Si layer 60 as the diffusion source, an emitter region 70 is formed. Therefore, if the emitter region of the element part is not omitted, the emitter aperture is not applied even in a check pattern resulting in an open state. Accordingly, the electrical characteristic is not allowed, and thus an omission state can be confirmed.

Abstract: PURPOSE:To accurate detect actual wheel steering angle information by providing a metallic core to a rod member which moves in the breadthwise direction of a car body by steering and then providing primary and secondary coils to the outer periphery at an interval. CONSTITUTION:A large-diameter part 12 is formed at some part on a rack shaft 4 which projects from a gear box 3 and metallic rings 13 and 13 made of copper, etc., are fitted to both ends to constitute a core 14. The primary coil 15 and secondary coils 16 and 16 on both sides are fixed successively on the outer periphery of the diameter part 12 on a car body side. Thus, a steering angle detector 11 is constituted. An AC voltage is applied to the coil 15, which is driven; when a core 14 moves right and left, a secondary voltage corresponding to its movement quantity is developed between the coils 16 and 16. Consequently, the moving direction and quantity of the shaft 14 are detected directly and the steering direction and angle of the front wheels 6 are therefore detected. A control signal 22 based on the steering information on the front wheels 6 and car speed information is inputted to a motor 23 and the rotation of the driving shaft 24 of the motor 23 is transmitted through a rear wheel steering gear box 25, a rack shaft 26, and a knuckle 27 to drive the rear wheels 28.

IPC: H01M2/36
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a simple immersion method of electrolyte capable of inhibiting a liquid overflow at the time of immersion of a sealed lead-acid battery. SOLUTION: A first immersion is carried out with 60-90% of a predetermined amount of electrolyte while an internal pressure of cell chamber of sealed lead- acid battery is retained to an atmospheric pressure.
