摘要： A frequency control and phase control for a voltage controlled oscillator (50) of a phase synchronizing circuit (100) comprise the current paths of two systems. A frequency control system comprises a filter (75) which converts an impulsive output current (i1) of a charge pump (70) driven by phase error signals (X1, X2) into a DC voltage, and a resistor (R1 or R2) which converts the DC voltage into a DC current (i3). The phase control system comprises a charge pump (80) which generates an impulsive output current (i2) from the phase error signals (X1, X2). The frequency and phase of an oscillation output (VOUT) of the voltage controlled oscillator (50) are controlled by a synthesized current (i4) which is the sum of the DC current (i3) and output current (i2). When the data transfer rate of an input signal (SIN) is changed, it is possible, by varying the values of the currents (i3, i2) through the switchover of switches (SW1, SW2), to make a natural angular frequency proportional to the transfer rate, keeping a dumping coefficient unchange. Thereby, a phase synchronism corresponding to the data transfer rate of a wide range can be realized.

摘要： A high speed synchronization pulling-in technique of a phase synchronizing circuit which is used in magnetic disc devices. When a circuit (1) for detecting a synchronous field detects a synchronous field, a selector (2) selects read data (RD), and a circuit (46) for stopping/restarting oscillation stops the oscillation of an oscillating circuit (40) by an output (RS) of a circuit (50) for controlling the timing of the oscillation. After passing bits of several bytes, the circuit (46) restarts the oscillation of the oscillating circuit (40) by an output (RS) of the circuit (50). A circuit (60) for adjusting a pulse width causes the fall of the read data (RD) to coincide with the oscillation restart by adjusting the pulse width of its output (SIN) to a delay time for restarting, and performs the high speed synchronisation pull-in.

摘要： A voltage-controlled oscillating circuit (60) in a phase-locked loop comprises a voltage-to-current converting circuit (62) and a current-to-frequency converting circuit (34). The voltage-to-current converting circuit (62) has a differential voltage-to-current converting circuit (64), current-to-current converting circuit (66), and current addition/subtraction circuit (68). In the differential voltage-to-current converting circuit (64), only the deviation or difference ( DELTA VCN) of the control voltage (VCN) from VDD/2, not its absolute value, is converted into current as the control current (ICN). Thus, the center frequency of oscillation frequency does not become the function of the control voltage (VCN) but it is controlled by only the offset voltage (VB2). Therefore, the center frequency can independently be set by changing the offset voltage (VB2). This is especially effective for the zone bit recording requiring a wide frequency band.

摘要： A PD (81) is positioned at a predetermined position on an optical table, the rotation of a resist master (110) is stopped, a focusing laser (73) is driven, and a head (77) is positioned in a proper position by a head slider control circuit (101). The master (110) is turned, a focusing servo circuit (103) is started and, the PD (81) is moved horizontally by a focus fine adjustment circuit (99) by a minute distance corresponding to an estimated adequate focus position data. Since the difference between voltage signals from the two output terminals of the PD (81) is varied because of the surface vibration and minute movement caused by the rotation of the master (110), a differential amplifier (103a) moves a recording lens (77a) vertically by a distance of several microns so as to make an error signal zero. Numerical information on a digital display (93) at this time is compared with the focus position data. When both of them agree with each other, the focus position data is employed as an adequate focus position data and used for the initial setting of the adequate focus position. When they do not agree with each other, the numerical information is employed as the adequate focus position data and the focus position data is rewritten. By using the numerical adequate focus position data, the inital setting of the adequate focus position matching the type of the resist master can be carried out easily.

摘要： An inexpensive small-sized PLL (phase-locked loop) oscillator for use as the clock source of a computer, etc., which can output such a high frequency about 40 MHz that is difficult to obtain from a fundamental-based crystal oscillator. The oscillator operates as stably as the fundamental-based crystal oscillator does, is easy to set a frequency, can be produced in a short lead time, and can be easily handled like the conventional crystal oscillator. The PLL oscillator is housed in a package, which contains a piezoelectric vibrator, an oscillation circuit for driving the vibrator, and a PLL circuit which receives a reference signal from the oscillation circuit. The output frequency of the PLL oscillator is determined by the oscillation frequency of the oscillation circuit and the scaling factor of the programmable divider of the PLL circuit so that a prescribed output frequency can be obtained by selecting the corresponding scaling factor, which may be stored in a programmable read-only memory.

摘要： A piezoelectric vibrator so assembled that a space may be formed between a vibrating piece and a plug, with a conductive resin-made connection layer being formed for connecting, to the vibrating piece, a slab-like lead which has its top end opened in a U-shaped form. The top end of the lead can absorb shock due to its elasticity. Before forming the connection layer, a temporary fastening layer is formed between the top end of the lead and the vibrating piece using UV curing resin, or silver paste is applied to either the top end or the vibrating piece to increase the workability. By this method, piezoelectric vibrator units, which have a high resistance to shock and have a little change in frequency when being left in a high temperature environment and which are very reliable, can be mass-produced at low cost.

摘要： A power supply device for rectifying or blocking reverse current of power from an internal generator provided in a portable electronic equipment, such as, fit electronic equipment to be worn around the arm, by using a unidirectional unit including a diode, a by-pass switch connected in parallel with the diode, and a controller for turning on the by-pass switch when a forward voltage is generated in the diode, thus substantially eliminating the loss accompanied by the forward voltage at the time of power supply. Since the electromotive voltage of the generator which can be internally provided in the above type of electronic equipment ranges from a level substantially the same as the forward voltage to approximately several times the forward voltage, the rectification efficiency may be significantly improved by using the unidirectional unit.
