摘要： In an optical disk recording device for projecting a recording light beam onto an optical disk to form 3T-11T pits in a land of the optical disk, timing to sample and hold a reflected light detection signal for tracking servo control is delayed behind timing to sample and hold the reflected light detection signal for wobble signal detection. Further, a sample-and-hold time period of the reflected light detection signal for tracking servo control is set to be shorter than a sample-and-hold time period of the reflected light detection signal for wobble signal detection. Such arrangements permit appropriate recording, even at high recording speeds, irrespective of residual optical axis deviations.

摘要： A method for manufacturing a magnet using an apparatus including a die, a first punch, and a second punch for compacting magnet powder is disclosed. Magnet powder is compacted with the first and second punches to produce a compact of the magnet powder. The distance between the first and second punches is increased to reduce the pressure applied to the compact from the first and second punches. Lowering of the die is started after the decrease of the pressure is started and before it is halted. The compact is completely ejected from the die before the pressure becomes zero.

摘要： A medical wire includes a conductive wire body and an implanted device connected to the distal end of the wire body through a joint member. The medical wire is inserted through a patient's tubular organ, thereby guiding the implanted device to the intended site in the patient's body. In this state, a monopolar high-frequency current is applied to the joint member through the wire body, thereby heating the joint member to cause it melt and sever, whereby the implanted device is detached from the wire body. There are thus provided a medical wire having an implanted device, which permits depositing the implanted device at the intended site in the patient's body by a simple operation within a short period of time, a mechanism which is simple in structure and highly reliable, and a method for depositing the implanted device of the medical wire is also provided.

摘要： A hysteresis circuit producing a relatively stable hysteresis output signal, which includes a power source, a reference potential source, a transistor, a constant current source, output means and means for detecting the collector current and for controlling the constant current source. The transistor is connected at its collector to the power source via the constant current source and at its emitter to the reference potential source. The constant current source supplies a constant current switchable between first and second levels. The output means is responsive to the first and second levels of current for deriving a bilevel hysteresis output signal dependent on the first and second levels of current. The detecting and controlling means detects the collector current of the transistor and controls the current source between the first and second levels of current in response to the collector current.

摘要： A sampling pulse generator circuit for a stereo demodulator circuit of a sample and hold system is disclosed. The pulse generator circuit uses pilot signals of an FM stereo broadcast as an input and produces output sampling pulses, which are phase-synchronized to the stereo subcarrier but have a 180.degree. phase difference to each other. The pulse generator circuit comprises a phase lock loop circuit having a multiple number of frequency dividers arranged in cascade. Selected outputs of these frequency dividers are logically summed to produce the output sampling pulses with a predetermined and stable pulse width.
