摘要： In a removable disk storage apparatus, a reading/writing head can be stably and reliably moved so as to correspond to an information recording medium. A rotation supporting member for supporting the reading/writing head is formed of a rotary arm and an elastic supporting member fitted to a tip end portion of the rotary arm for supporting the reading/writing head. The rotary arm member is formed by bending it so that it should be dogleg-shaped. The elastic supporting body is fixed on a tip end portion of a bent portion thereof in the extended direction in which the elastic supporting body is bent. The rotary arm is inserted into a disk cartridge substantially straight with its tip end being faced to the disk cartridge, and then supported by a ramp on a center line thereof.

摘要： A door 20 is rotatably attached to a disk cartridge 1. In mounting the disk cartridge 1, an opening and closing pin 224 moving along a groove 223 is engaged with the door 20 and the door 20 is opened. For example, when the opening and closing pin 224 cannot return to a normal standby position by some cause, a front face of the door 20 and a projected streak portion 206 are brought into contact with each other and the disk cartridge 1 cannot be inserted further. Therefore, even when the disk cartridge 1 is inserted in a state where the door 20 is not opened, there is avoided beforehand an accident where the disk cartridge 1 collides with a head, a lamp or the like to cause the destruction thereof.

摘要： In a vehicle door mirror device, a bracket is divided into a frame and a case member. Thus, the frame and the like for a vehicle right side and for a vehicle left side can both hold a mirror at a vehicle rear side thereof. A mounting hole and a supporting hole of a case member are provided to be symmetrical with respect to a vertical plane which passes through a widthwise direction center of the case member. Thus, even if a common case member is used both for a vehicle right side and for a vehicle left side by left and right sides of the case member being reversed, the mounting hole of the case member can be mounted to the frame and the like for the vehicle right side and the vehicle left side.

摘要： There is provided a driver circuit which does not require a large driving current, even when a logic circuit having a large capacity component is connected as the load. When the input voltage level is “H”, the first driving means inserted between the source and the load is maintained at the on state and it is turned off when it is detected by the first detecting means that the voltage level of the load exceeds the first voltage level. When the input voltage level is “L”, the second driving means inserted between the ground and the load is maintained at the on state and it is turned off when it is detected by the second detecting means that the voltage level of the load is below the second voltage level. The above mentioned first voltage level is higher than the logic threshold of the logic gate for receiving signals from the driver circuit, and the above mentioned second voltage level is lower than the logic threshold of the logic gate for receiving signals from the driver circuit.

摘要： There is disclosed an SRAM including a number of memory cells located in the form of a matrix. When data "0" is written to a memory cell 100, a precharge signal PC is brought to a high level so that a bit line D0 is brought into an electrically floating condition. A corresponding power switch 30 is turned off so that a pseudo-ground line SS0 is brought to an electrically floating condition. A corresponding equalizing transistor 20L is turned on so that the bit line having a power supply voltage Vdd as an initial potential and the pseudo-ground line SS0 having a ground voltage Vss as an initial potential are electrically connected to each other, so that the potential of the pseudo-ground line SS0 is elevated to a potential Veq which is determined by a ratio in capacitance of the bit line and the pseudo-ground line. As a result, the data holding capability of the memory cell 100 is lowered, and therefore, when a corresponding word line is pulled up, a latch in the memory cell 100 is quickly inverted, so that the writing operation is completed at a high speed. After the writing operation, the potential of the bit line D0 is returned to the initial potential Vdd. In this operation, since the potential of the bit line D0 was lowered only to the potential Veq, the potential of the bit line D0 is returned to the initial potential Vdd quickly with a reduced power consumption.
摘要翻译：公开了包括以矩阵形式定位的多个存储单元的SRAM。当将数据“0”写入存储单元100时，使预充电信号PC达到高电平，使得位线D0进入电浮动状态。相应的电源开关30被关闭，使得伪地线SS0变为电浮动状态。相应的均衡晶体管20L导通，使得具有作为初始电位的电源电压Vdd的位线和具有接地电压Vss作为初始电位的伪地线SS0彼此电连接，使得电位将伪地线SS0提高到由位线和伪地线的电容比确定的电位Veq。结果，存储单元100的数据保持能力降低，因此当对应的字线被上拉时，存储单元100中的锁存器被快速反转，使得写入操作以高速完成。在写入操作之后，位线D0的电位返回到初始电位Vdd。在该操作中，由于位线D0的电位仅降低到电位Veq，所以位线D0的电位以降低的功耗快速恢复到初始电位Vdd。

摘要： The present invention provides an technique for compensating a operation speed variation based on a principle that a circuit operation speed is adjusted by reflecting a delay time of an internal circuit itself that is an object of the operation speed fluctuation compensation.An internal circuit (1 in FIG. 1) has a critical path with an output terminal pair that outputs the identical logical values till its each operation is finished, and data in a complementary signal format as soon as its each operation is finished. A logical gate (2 in FIG. 1) can detect its operation end by sensing the signal transition into a complementary signal format at the output terminal pair of the internal circuit.
