IPC: B21J5/08
Filed: 1980-02-21
Abstract: PURPOSE: To obtain a lightweight leaf plate type hinge having high strength by punching a flat plate then subjecting the same to cold forging thereby forming shaft cylinders and leaf plates with one piece of metal.  
     CONSTITUTION: A flat plate blank material is punched to obtain a hinge working plate having a leaf plate part 11a and shaft cylinder working parts 11b. This plate is grasped between a male die 12 and a female die 13, and a punch 14 is driven to the end face of the cylinder shaft working plate parts 11b, whereby it is upset and cold forged. Thereby, the upset material is moved toward the shaft cylinder forming parts 12a, 13a and shaft cylinder working bulged parts 11b' are formed at the end of the leaf plate part 11a. Thence, the parts 11b' is pierced to form shaft insertion holes 11c, and mounting holes 11d is pierced at proper places of the leaf plate part 11a. By this method, the leaf plate type hinge 11" of which the shaft cylinder parts 11b" and leaf plate 11a consist of one piece of metal is obtained.

Abstract: PURPOSE:To execute the inspection without generating an optical disk, to bring the inspection process to lavor saving and to shortening said process by specifying the wavelength of a light source light and a value of an aperture ratio of an objective lens at the time of inspection of an optical master disk or a stamper. CONSTITUTION:At the time of inspecting an optical master disk or a stamper, wavelength of light of a light source 1 is set to 1/n of wavelength used for driving an optical disk by a wavelength converting plate 3, and a value of an aperture ratio of an objective lens 6 is also set to 1/n. In this regard, (n) denotes a refractive index of the optical disk.

Filed: 1991-01-23
Abstract: PURPOSE:To correct the positional deviation of an image and to improve image quality by setting the rotational period of an image forming medium to integer part of the rotational period of a transfer medium. CONSTITUTION:The rotational period T1 of the image forming medium 1i is set at one part of an integer of the rotational period T2 of the transfer medium 2, so that the periods of transfer positional deviation fluctuations as the least common multiples of the T1 and T2 are shortest, and equalized to the period of one rotation of the transfer medium 2. Therefore, when a transfer positional deviation is corrected, it is corrected within the range of the period of one rotation of the transfer medium 2. In other words, the positional deviation value of the image transferred from each image forming medium 1i on the position of the equal rotational angle of the transfer medium 2, is measured, and stored in a position storage means 4, at each image forming medium 1i. A correcting means 5 outputs a signal that the interval of scanning is corrected based on the data of the positional deviation, and the corrected image is formed on each image forming medium 1i.

IPC: G01M3/00
Filed: 1995-02-09
Abstract: PURPOSE: To obtain a method for detecting leakage of city gas in a service pipe without requiring any digging work of ground. CONSTITUTION: A gas meter 3 is provided with a pressure sensor 5 and installed on a leakless duct 2. The pressure sensor 5 measures the pressure difference when no gas flows through the duct and when gas flows through the duct and the measurement is stored along with the flow rate as initial values. Subsequently, the flow rate and the pressure difference are measured every time when the gas flows to be used for a gas apparatus. The pressure difference is subjected to flow rate correction and compared with the initial value thus detecting leakage of gas. Since leakage of gas from a duct coupling the gas meter 3 and a main or branch line 1 can be detected without requiring any digging work, manpower can be reduced and since leakage is monitored every time when the gas is used, safety is enhanced.
