Title: Servo-brake system
Inventor: OOTA YOSHIKI
IPC: F16D65/28
Filed: 1980-07-31
Abstract: PURPOSE:To obtain a braking power at a fixed enlarged power rate in a large- sized autocycle by using a staged-piston which permits the escape at a connecting port according to a grasping power for controlling a nonreturn valve of a brake hydrostatic pressure generator. CONSTITUTION:When a brake lever is grasped, a manual hydrostatic pressure is transmitted to a brake cylinder via a connecting port 22. By this braking, a calliper 8 is swayed to generate a hydrostatic pressure in a servo hydrostatic pressure generating chamber 16 via a push rod 35, but, at the initial stage of the braking, a nonreturn valve 29 is closed, and the hydrostatic pressure cannot be transmitted. When the grasping power is increased, the manual hydrostatic pressure is increased to shift a staged-piston 17 to the right against the force of a spring, and the nonreturn valve 29 is opened to increase the braking force. When the servo hydrostatic pressure surpasses a certain value, the piston 17 is shifted to the left, and the nonreturn  valve is closed to cut the servo work. When a sudden braking is given, a valve  body 23 escapes, and a valve seat 28 is closed to transmit the manual high hydrostatic pressure directly.

Title: Formation of film
Inventor: SASABE SHUNJI
IPC: H01L21/316
Filed: 1986-05-12
Abstract: PURPOSE:To prevent the adhesion of quartz rich in silicon, and to obviate the generation of a foreign matter while checking the large reduction of the rate of film formation by mixing 0.5% or less of oxygen into argon gas. CONSTITUTION:When the quantity of oxygen mixed into argon gas is altered at approximately 0.1%, characteristics as shown in the graph are acquired. That is, when the quantity of oxygen is increased, the difficulty of the peeling of extraneous quartz is augmented and the generation of foreign matters is inhibited, but the rate of film formation is decreased: when the quantity of oxygen is reduced, the rate of film formation is accelerated, but the difficulty of the peeling of extraneous quartz is lowered and foreign matters are easy to be generated. Consequently, the quantity of oxygen mixed into argon gas is set so as to be brought to 0.5% or less at most centering around 0.1%. Accordingly, both points of the rate of film formation and the difficulty of the peeling of extraneous quartz can each be satisfied.

Abstract: PROBLEM TO BE SOLVED: To obtain a metal detector which is, in principle easy to judge a phase shift for adjusting the phase of a detection signal, while shortening the time required for the phase adjustment, when an object to be inspected is placed in an alternating magnetic field. SOLUTION: In this metal detector, an oscillation coil 2 is excited by an alternating signal to generate an alternating magnetic field and signals from receiving coils 3a and 3b, interlinked to a magnetic flux are demodulated in the magnetic field to detect metal in an object W to be inspected which is conveyed between the oscillation coil and the receiving coils. In this case, a plurality of detection circuits 6a, 6b... for demodulating the signals from the receiving coils are connected to a plurality of phase shifting circuits 9a, 9b... which adjust the phases of detection signals to supply the results to the respective detection circuits and a plurality of averaging circuits 10a, 10b... which average demodulated signals from the detection circuits to transmit resulting output signals to a judging circuit 8.  Thus, the phases of the detection signals from the individual phase shifting circuits are adjusted to be mutually differentiated by output signals from the judging circuit 8, and the results are supplied to the respective detection circuits.
