Title: Orientation system for optical cable break point
Inventor: YAMASHITA MAKOTO
IPC: G01M11/00
Filed: 1979-06-22
Abstract: PURPOSE:To make it possible to detect a fiber break point in real time by leading supervisory signals, generated by two break-point orientation units, to a light repeater, by making a supervision over the break of supervisory signals, and by transmitting and receiving obtained information by those orientation units. CONSTITUTION:Light repeater 8 operates through remote or local electric power feed, but even if an fiber is broken causing the break of electric power feed, terminal stations A and B can detect the interruption of supervisory signals since the signals propagate earlier than the functions of light repeater 8 are disabled due to the break of power feed, so that orientation to a break point can come into effect. Thus, supervisory signals generated by break-point orientation units 4 and 5 are led to main repeater 9 and subordinate repeater 10 and pieces of information Ta and Tb on a supervision over those supervisory signals are transferred between break-point orientation units 4 and 5 via separately provided control circuits, so that the break point of the fiber can be detected in real time.

Title: Method and device for controlling arc welding power source
Inventor: NAKANISHI SADAO
IPC: B23K9/06
Filed: 1983-05-06
Abstract: PURPOSE:To prevent arc breakage without providing a base power source and to simplify circuit constitution by increasing a command value of an arc voltage to increase welding current when the welding current decreases to the set current value or below. CONSTITUTION:The deviation at a deviation detecting point 5 heads toward the direction of decreasing the value of a voltage command signal IS when an arc voltage VA increases upon generation of a disturbance. As a result, the output signal level of an integrating circuit 7 falls and the H level period of a pulse signal SP is shortened, by which the conducting width of a switch SW is shortened. Current IW is then decreased but when the feedback quantity If corresponding to IW attains the state of If<¦ITHO¦, the output voltage VC of a compensating amplifier 15 attains Vmax and is supplied as an addition signal to the point 5. As a result, the deviation at the point 5 heads toward the direction of increasing the value of the signal IS by which the conducting width of the switch SW is increased. The generation of arc breakage is thus obviated without decrease of the current IW from the threshold current ITH.

Abstract: PROBLEM TO BE SOLVED: To uniformly coat with less coating liquid by coating the surface of a board with solvent of coating liquid or another solvent which can dissolve the liquid as precoating liquid before coating the board with the liquid, and coating it with the liquid in such state that the precoating liquid is not completely dried. SOLUTION: Before coating a board 2 with coating liquid, the board 2 is fixed to a chuck 4, and precoating liquid 6 is dropped from a nozzle 5 while rotating the board 2. After the liquid 6 is dropped for about 1sec, it is dried while spinning it for 5sec, and the liquid is dropped onto the board 2 from another nozzle 5 in such state that the liquid 6 slightly remains on the board 2. At this time, since the board 2 is moistened with the liquid 6, the coating liquid is rapidly spread over the entire surface of the board 2, and then the rotation of the board 2 is accelerated to finish the coating. Thus, it can be uniformly coated with less liquid.
