Filed: 1993-04-01
Abstract: PURPOSE:To obtain the blank for a magnetic disk, being free from a local shape failure and excellent in a degree of flatness by collapsing and obviating a small distortion whose straightening is difficult in a blanking process, and executing easily and surely straightening executed by pressure stress relief annealing. CONSTITUTION:At the time of blanking a ring-like blank B from a belt-like Al plate stock S by using a double action die, the outside periphery of a blanking object blank part B' of the Al plate stock S is inserted and pressed by the upper and the lower outer dies 1a, 2a and held, and also, its center part is subjected to rolling reduction by a hole punch 1c and bulged like a wide angle truncated cone, and a uniform plastic deformation is generated in the blanking object blank part B'. Thereafter, by blanking the center hole and the outside peripheral edge by the hole punch 1c and an outer edge punch 1b, a blank B like a prescribed ring is formed, and subsequently, by allowing its blank B to be subjected to pressure stress relief annealing, the degree of flatness is straightened. In such a way, the blanked blank is uniform and free from a small distortion although it has a large deformation, and the degree of flatness can be enhanced easily by the subsequent pressure stress relief annealing.

Abstract: PURPOSE: To prevent generation of a recess type flaw so as to suppress a coating bank when a thin film is coated so as to accomplish uniform image formation by restricting surface roughness within a specific range in the circumference direction of an aluminum base pipe. CONSTITUTION: Drawing or ironizing is carried out for a photosensitive drum aluminum base pipe 1, and its surface roughness in the circumference direction is controlled to be Rmax 0.5-1.0μm. As a stripe flaw 2, which is due to die meshes and the like, extends in the longitudinal direction of the base pipe 1, in other words, in the machining direction for the base pipe 1, the stripe flaw 2 can be detected when unevenness in the circumference direction is detected. If the surface roughness in the circumference direction of the element pipe 1 exceeds 10μm by Rmax (maximum height), a wrinkle flaw 3 remains and causes a coating bank when the base pipe 1 is used as a photosensitive drum in thin film coating of the photosensitive layer. If Rmax is 10μm or less, a coating bank makes no trouble. If Rmax is 0.5μm or more, lubricating oil penetrates in a recess part on the element pipe surface and formation of oil bit can be prevented.

Abstract: PURPOSE: To accurately control the air-fuel ratio in the theoretical air-fuel ratio, by changing the delay time of a delay circuit mounted in order to respond the difference of the response time of an air-fuel ratio sensor in response to the temperature of exhaust gas.  
     CONSTITUTION: An air-fuel ratio control unit 30 consists of each circuit of a comparison 40, a delay 50 and an integration 60. The rise of electromotive force is steep or gentle in response to the high or low temperature of exhaust gas in a sensor 20 for obtaining the air-fuel ratio from exhaust gas. The signals of the sensor 20 are compared with theoretical air-fuel ratio voltage V s  by means of a comparator 44, and 1 or O output signals are emitted in response to the concentration of the fuel of mixture. Since a condenser 51 of the delay circuit 50 alters discharge time in response to electric resistance value depending upon the temperature of an exhaust temperature sensor 21, the rise of voltage V c  becomes easy when the temperature of exhaust gas is low, the 1 level output time of a comparator 54 is prolonged, and a fuel feeder 12 is controlled, thus maintaining the theoretical air-fuel ratio.

Abstract: PURPOSE:To detect an obstacle in a wide-range area near a photographing lens and to prevent the vignetting of a photographic picture by providing an infrared receiving means, an infrared projecting means and a detecting means. CONSTITUTION:This optical equipment is provided with 1st to 4th infrared light emitting elements 13, 14, 16 and 17 functioning as infrared projecting means for detecting an obstacle and a light receiving element 12 functioning as a light receiving means for automatic focusing. The light emitting elements 13, 14, 16 and 17 are controlled by a main IC controlling a camera 10. In a state where a finger is put on the right lower part of the photographing lens, for example, infrared light emitted from the 3rd light emitting element 16 is radiated to the finger and received as reflected light by the light receiving element 12 and inputted in a sensor. The sensor converts the light into an electrical signal and performs the waveform shaping of the light by an AFIC for autofocusing, and transmits it to the main IC. The A/D of the main IC converts the signal into a digital signal and transmits it to a CPU. Thus, the obstacle which is an obstruction in the photographic picture near the photographing lens is detected, and a photographer is warned of it.
