    • A self-expanding mount controls transmission of vibration of a vibration source to a base. A main liquid chamber is defined between a resilient member fixed to the vibration source or the base and a casing fixed to the base or the vibration source. A metallic bellows is driven in response to a control signal corresponding to vibration of the vibration source, cause a variation in the pressure of liquid within the main liquid chamber. This variation in the liquid pressure causes contraction and expansion of the resilient member to thereby control the transmission of vibration of the vibration source to the base. A cylinder is formed in the casing and defines part of the main liquid chamber. A driven member is received in the cylinder for axial displacement therein in response to the above control signal. The driven member may be a bellows or a piston.

    • A rotary piston vacuum pump has a rotor eccentrically disposed in a cylinder and mounted therein for revolution in rolling contact with the cylindrical inner peripheral surface of the cylinder so that a crescent-shaped space is defined between the rotor and the cylinder and moved around the axis of the cylinder. A vane is radially reciprocally mounted in a vane chamber having an inner end open to the cylindrical inner peripheral surface of the cylinder. The vane has an inner end in sliding contact with the outer peripheral surface of the rotor to divide the crescent-shaped space into a suction chamber in communication with a suction port and a discharge port to be communicated with a discharge port having an inner end open in a wall of an outer part of the vane chamber. The rate of communication between the discharge port and the discharge chamber through the outer vane chamber part is varied by the reciprocal movement of the vane so that the communication is interrupted at least when the point of contact between the rotor and the cylinder inner peripheral surface reaches the vane.

    • Temperature of power generating cells is measured, and, if the measured temperature is lower than a preset standard operating temperature, control is performed for zeroing an allocated amount of cooling air via an air allocation mechanism. During a startup period, cooling-air introduction openings are closed with reacting-air introduction openings kept open and an air-sucking-in fan activated. Thus, the entire amount of introduced air is caused to flow through the reacting-air introduction openings into the cells for reaction with hydrogen with a minimized cooling effect so that the power generation reaction can be promoted, which can reduce a time necessary for the cell temperature to increase up to a predetermined operating level. By constantly performing the control for zeroing the allocated amount of cooling air during the startup and subsequent periods, the power generating cell temperature is constantly allowed to rise readily as desired.
    • 测量发电电池的温度,如果测量温度低于预设的标准工作温度,则通过空气分配机构对分配的冷却空气量进行调零。 在启动期间,冷却空气导入口关闭,反应空气导入口保持打开,吸入风扇启动。 因此,使引入的空气的总量通过反应空气导入开口流入细胞以与氢反应,并以最小的冷却效果,从而可以促进发电反应,这可以减少电池所需的时间 温度升高到预定的操作水平。 通过不断地执行用于在启动和随后的时段内对分配的冷却空气量进行归零的控制,发电单元温度被恒定地允许随意地上升。

    • An object of the present invention is to provide a charge amplifier which can be operated at low cost so that electric charge generated in a piezoelectric pressure sensor having one end grounded is converted into a voltage signal.In the charge amplifier (1) according to an embodiment of the present invention, a plus side power source input terminal of an operational amplifier (5) is connected to a plus power source (+5 V) while a minus side power source input terminal of the operational amplifier (5) is grounded, so that the operational amplifier (5) is supplied with a single power source. Further, an offset voltage lower than the plus power source voltage but higher than the ground potential is applied to a non-inverted input terminal of the operational amplifier (5). Accordingly, change of pressure in both positive and negative directions can be converted into a voltage signal with the offset voltage as its center though the operational amplifier (5) is driven by a single power source. That is, cost can be suppressed because a double power source is not required.
    • 本发明的目的是提供一种可以以低成本操作的电荷放大器,使得在具有一端接地的压电式压力传感器中产生的电荷被转换为电压信号。 在根据本发明的实施例的电荷放大器(1)中,运算放大器(5)的正侧电源输入端连接到正电源(+ 5V),而负侧电源输入端 运算放大器(5)接地,使得运算放大器(5)被提供有单个电源。 此外,低于正电源电压但高于接地电位的偏移电压被施加到运算放大器(5)的非反相输入端子。 因此,通过运算放大器(5)由单个电源驱动,正负方向的压力变化可以转换为以偏移电压为中心的电压信号。 也就是说,可以抑制成本,因为不需要双电源。
