Title: Production of contact point material
Inventor: TSUJI MASAYUKI
IPC: C22C5/06
Filed: 1985-02-25
Abstract: PURPOSE:To obtain a contact point material which has much higher welding resistance and does not contain harmful components by subjecting an Ag alloy which is added preliminarily with a small amt. of the element having the high rate of volumetric expansion by oxidation and contains a small ratio of Li and Pb to a heating treatment in an oxidation atmosphere to disperse the oxide of the Li and Pb into the Ag. CONSTITUTION:The Ag alloy contg. 0.05-3wt% Li and 3-6% Pb is subjected to the heating treatment at, for example, 700 deg.C in the oxidation atmosphere to disperse the Li and Pb in the form of the oxide into the Ag. The element having the high rate of volumetric expansion by oxidation is required to be preliminarily added into the above-mentioned alloy at 0.1-5wt% ratio by the total weight of the alloy. The internal stress of the resulted contact point material increases with the volumetric expansion of the added element so that the hardness and welding resistance thereof are improved. Preferably >=1 kinds among Si, Cu, Zn, Cd, Sn and Sb are used for the above-mentioned element to be added.

Title: Hydraulic system
Inventor: MATSUMOTO NORIO
IPC: F15B20/00
Filed: 1981-03-13
Abstract: PURPOSE:To prevent a trouble from being caused by the wrong action of a servo valve in power failure, by providing a check valve between the servo valve and a hydraulic cylinder and reducing the pilot pressure to automatically shut off a pilot valve in the power failure. CONSTITUTION:Pilot check valves 22, 23 are provided between a servo valve 12 and a hydraulic cylinder 11. In power failure, a solenoid valve 21 is deenergized to connect pilot pipes 25, 26 to each other so that the pressurized oil in the check valve 23 flows out into a pipe 13 and the pilot pressure is reduced. For that reason, the check valves 22, 23 function to prevent the counter flow to stop the flow of pressurized oil between the hydraulic cylinder 11 and the servo valve 12 so that the hydraulic cylinder keeps its position. When a valve 31 is manually closed and valves 27, 30 are manually opened, the counter flow preventive function of the check valves 22, 23 is lost due to the pilot pressure so that the hydraulic cylinder 11 can be operated by adjusting the degree of opening of the valve 30.

Title: Image forming device equipped with automatic focusing function and horizontal synchronizing function
Inventor: HIROSE YOSHIHIKO
IPC: B41J2/44
Filed: 1990-02-18
Abstract: PURPOSE:To decrease the position adjustment man-hours of each detector by arranging two detector for horizontal synchronism and defocusing on the same support member and adjusting only the position of the defocusing detector, and guiding luminous flux properly into the horizontal synchronism detector as well. CONSTITUTION:For an increase in the S/N of a defocusing detection signal, the fixation position of the support plate 5 is adjusted so as to scan the optical center of the defocusing detector 3 with a laser beam. When the support plate 5 does not have accuracy, slits 2 and 4 are scanned with the laser beam slantingly as shown by arrows Y and Z, but the laser beam passes the center of the slit 4 of the defocusing detector 3. The support plate 5 is thus adjusted and then even if the slits 2 and 4 are scanned slantingly with the laser beam as shown by arrows Y and Z, the laser beam crosses the wide slit 2 of the horizontal synchronism detector 1 and then the AF function and horizontal synchronizing function operate normally only by performing relatively easy adjustment so that the beam passes the center of the slit 4.
