摘要： In a so-called multiline driving system, (1) a selected period is divided into a plurality of subselected periods (t11, t21, t31 and t41) and the subselected periods are dispersed in one-frame period, and (2) each subselected period is further divided into a plurality of divided subselected periods ((s1, s2), (s3, s4), (s5, s6), (s7, s8)). The potentials of selected signals are interchanged in the divided subselected periods in one frame so as to offset the influence of a spike-like voltage from the scanning signal impressed upon adjacent scanning electrodes. By this invention, (1) uneven display in the direction of signal electrodes (generally, in the longitudinal direction) can be suppressed, (2) uneven display in the direction of signals electrodes does not become more marked and no flickering occurs even when displayed contents momently change, and (3) no uneven display occurs in the direction of the scanning electrodes (generally, in the lateral direction).

摘要： A display device employing a multi-line driving method, which improves display quality by applying contrivances to the construction of a data line driving circuit and a scanning line driving circuit. Frame memories (252) are prepared for two frames, for example, and they are alternately switched between input and output for each frame. When the memory of only one frame is used, the data corresponding to the number of scanning lines driven simultaneously are gathered together and simultaneously written. In this way, the deterioration of display quality can be prevented. A decoder in a data line driving circuit is formed into a ROM (262). Accordingly, the construction of the data line driving circuit can be simplified. The voltage applied to each data line is fixed during the period in which it does not contribute to image display. In this way, cross-talk can be prevented. Data necessary for selecting a scanning line and data necessary for determining a voltage to be applied to the scanning line are separately processed in a scanning line driving circuit (2200). In this way, the construction of the scanning line driving circuit can be simplified. When a scanning voltage pattern is periodically changed, the scanning line driving circuit and the data line driving circuit exchange information on the scanning voltage pattern with each other.
摘要翻译：一种采用多线驱动方法的显示装置，其通过对数据线驱动电路和扫描线驱动电路的构造施加设计来提高显示质量。例如，帧存储器（252）准备用于两个帧，并且它们在每帧的输入和输出之间交替地切换。当仅使用一帧的存储器时，与同时驱动的扫描线数相对应的数据被聚集并同时写入。以这种方式，可以防止显示质量的恶化。数据线驱动电路中的解码器形成为ROM（262）。因此，能够简化数据线驱动电路的结构。施加到每个数据线的电压在其对图像显示没有贡献的时段期间是固定的。以这种方式，可以防止串扰。在扫描线驱动电路（2200）中分别处理选择扫描线所需的数据和确定施加到扫描线的电压所需的数据。以这种方式，可以简化扫描线驱动电路的结构。当扫描电压图案周期性地改变时，扫描线驱动电路和数据线驱动电路将关于扫描电压图案的信息彼此交换。

摘要： A display driving method, wherein only one voltage of an unselected scanning line is used, and when the displaying of an image by display elements is not carried out, the voltage level of data lines corresponding to the display elements is the voltage level of the unselected scanning line. The power consumption of the display can be reduced. The smallest possible area out of the whole screen is used for the displaying of an image, and the other area is put in a display-off state (display-off mode) by using this driving method. For example, the reduction of the consumption of the display in a standby mode is effected. The image display area and the area in a display-off state can be set freely, respectively. When the multiline driving method and the above-described driving method are combined, the power consumption can further be reduced.

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.
