Title: Synchronizing separation circuit
Inventor: KAWAHARA TOSHISHIGE
IPC: H04N5/10
Filed: 1986-06-20
Abstract: PURPOSE:To remove an equalizing pulse, to obtain stable horizontal and vertical synchronizing signals and to easily form an IC by obtaining a horizontal synchronizing signal from a monostable multivibrator selected at its time constant and using the obtained signal as a clock pulse to obtain a vertical synchronizing signal from a D-FF. CONSTITUTION:A monostable multivibrator 1 is triggered by the trailing edge of a composite video signal (a) and outputs a negative pole pulse signal (b) with pulse width t1 determined by a time constants of a resistor 4 and a capacitor 5. Thereby, the multivibrator 1 outputs a pulse signal with horizontal frequency fH masking a 1H/2 equalizing pulse and a vertical synchronizing signal within the vertical flyback time of the composite synchronizing signal. A monostable multivibrator 2 inputs a signal (b), separates a vertical synchronizing signal with pulse width t2 determined by the time constant of a resistor 6 and a capacitor 7 and outputs a continuous and stable horizontal synchronizing signal (c) masking the equalizing pulse. The D-FF 3 inputs signals (b), (a) to 1 clock input terminal and a data input terminal respectively and outputs the signal (a) to the Q terminal at the leading edge timing of the signal (b), so that only the vertical synchronizing signal is separated from the Q terminal and a signal (d) is outputted.

Title: Encapsulated liquid torque limiter
Inventor: MASUKO ETSUYASU
IPC: F16D7/06
Filed: 1986-06-20
Abstract: PURPOSE:To eliminate the necessity for stopping a drive unit immediately after interruption of transmission of torque, by encapsulating liquid in a cylinder bore and a discharge path thereby transmitting the torque without retreating a piston. CONSTITUTION:Force is applied in the retreating direction onto a piston 42 by the function of convex concave faces 48 of a ball 46, but since oil is encapsulated in a cylinder bore 40 and a discharge path 62 and the opening of the discharge path 62 is closed by a piston 72, the piston 42 does not retreat, nor a detection ring 30 retreat while resisting against the energizing force of a belleville spring 34. Consequently, the rotary driving force of a drive unit is normally transmitted to a driven device through the engagement between the ball 46 and the concave face 48, thus eliminating the necessity for stopping the drive unit immediately after interruption of transmission of torque.

Title: Patch plate for drilling circuit board
Inventor: TANAKA TAKASHI
IPC: B26F1/16
Filed: 1994-06-06
Abstract: PURPOSE:To improve the drilling workability and the durability of a drill by combining an aluminum foil having a specific hardness and a paper sheet impregnated with a resin with a curing type adhesive to form a patch plate. CONSTITUTION:A foil having the hardness of H10 or above and a paper sheet impregnated with a resin, e.g. a cellulose resin, are combined with a curing type adhesive to form a patch plate. The thickness of the aluminum foil is preferably set to 10-100mum, and the value outside this range is not preferable because the durability of a drill is deteriorated. The material and thickness of the paper sheet may be optional. A nitrocellulose resin is preferable for the cellulose resin. When a thermoplastic adhesive is used for the adhesive, it is melted by the heat at the time of drilling to shorten the drill life, therefore a thermosetting resin, e.g. an epoxy resin, is used. The abrasion resistance of the drill can be improved when an inorganic filler is contained in the paper sheet, impregnant resin, and adhesive.

IPC: G21C7/08
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To control a free-run distance of control rod according to the fluctuations in drive velocity at a reference braking initiation position. SOLUTION: If a control rod 12 is detected to have come to a reference braking initiation position by a position comparison part 28 based on the detection signal of a position detector 24, while the control rod 12 is inserted or withdrawn by driving a motor 16, whether or not the motor 16 velocity comes to the synchronizing velocity is decided from the velocity controller 30 in a timing controller 32. When the motor 16 velocity is at the synchronizing velocity, off-signal is output as it is from a drive circuit 18 to the motor 16 to initiate braking, and when the motor 16 velocity is below the synchronizing velocity, the off-signal is delayed by the time which corresponds to the deviation and output to initiate braking.
