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.
摘要翻译： PD（81）位于光学平台上的预定位置，停止抗蚀剂母体（110）的旋转，驱动聚焦激光（73），并且通过以下方式将头（77）定位在适当位置：磁头滑块控制电路（101）。主机（110）转动，聚焦伺服电路（103）启动，PD（81）由焦点微调电路（99）水平移动与估计的足够对焦位置数据相对应的微小距离。由于由于主机（110）的旋转引起的表面振动和微小移动，PD（81）的两个输出端子的电压信号之间的差异是变化的，差分放大器（103a）使记录透镜（77a）移动）垂直延伸几微米的距离，以使误差信号为零。此时将数字显示器（93）上的数值信息与焦点位置数据进行比较。当它们都彼此一致时，聚焦位置数据被用作适当的聚焦位置数据，并用于初始设定足够的聚焦位置。当它们不一致时，使用数字信息作为适当的焦点位置数据，并且重写焦点位置数据。通过使用数值适当的聚焦位置数据，可以容易地进行与抗蚀剂母版类型匹配的适当聚焦位置的初始设置。

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.
