    摘要: If a local oscillation wave of a frequency approximately half the received signal frequency is input to a low noise amplifier 2, a dc offset voltage caused by the nonlinearity of the amplifier is produced, thus degrading reception sensitivity. This problem is resolved by disposing before the low noise amplifier 2 a filter means, such as a bandpass filter 12, band-elimination filter 13, or high pass filter 14, with characteristics for passing the received wave and suppressing a frequency band at approximately half the received wave frequency, thus preventing a radiation wave at substantially the same frequency as the local oscillation wave from being input to the low noise amplifier 2. A filter circuit 15 is also provided in the low noise amplifier 2 as a means for eliminating a radiation wave input to the low noise amplifier 2.

    摘要: A set of bonding pads are ultrasonically connected to a set of leads. The bonding pads are formed on a predetermined plane of a slider held by a slider holder accessible to the recording plane of a disk in a disk drive. The leads are held by the slider holder and have joints that are formed so as to respectively face each of the bonding pads. A front end plane of a wedge working on the joints is tilted in a direction in which the first sides of the joints correspond to external connection sides. The ultrasonic connection is completed by pressing the joints of the leads against the faced boding pads.

    摘要: When a thin film is formed on a flexible and filmy substrate by a vapor phase method, the substrate is prevented from warping to be caused by the internal stress remaining in the thin film. When the thin film is formed by the vapor phase method, the substrate is previously curved so that the stress acts in the direction canceling the internal stress remaining in the thin film to be formed prior to the filming. Accordingly, the stress of the curved substrate cancels out the stress remaining in the thin film formed on the substrate. The substrate having a thin film formed thereon is not warped, the stress in the interface between the thin film formed and the substrate is removed, and the thin film has no cracks to be caused by the stress.

    摘要: An auxiliary part mounting bracket for an in-line multi-cylinder engine. An oil pump, an auto-tensioner, an alternator, a water pump and a compressor are preassembled on the auxiliary part mounting bracket to form an assembly. This assembly is fixed to a side of the engine cylinder block by six bolts. One bolt is threadedly inserted into the cylinder block through a space defined between the upper oil pump and auto-tensioner and the lower alternator and water pump; two bolts are threadedly inserted into the cylinder block through a space defined between the upper positioned alternator and water pump and the lower positioned compressor. Thus, it is possible to enhance the assembling operation, when the plurality of auxiliary parts are fixed to an engine body through the auxiliary part mounting bracket.

    摘要: In a transmitter-receiver having a transmitting circuit and a receiving circuit, the present invention mitigates an interference between the transmitting circuit and the receiving circuit. A quartz-crystal oscillator is provided as a common reference signal source for the local oscillators and the relation among frequencies is determined so that the frequencies such as local oscillating frequencies and intermediate frequencies within the transmitter-receiver do not overlap each other. Interferences between the transmitting circuit and the receiving circuit are mitigated to prevent a characteristic deterioration, spurious radiation, etc. Thereby the transmitter-receiver may be reduced in size and weight. Further, by sharing a quartz-crystal oscillator having a high frequency stability, narrowing of bands in radio channel spacing may be readily achieved.

    摘要: A transport system installed in a cleanroom where clean air is caused to flow from a ceiling toward a floor. The transport system includes a vehicle for transporting loads, and a guide rail suspended from the ceiling to guide the vehicle. The vehicle has a main body for running along the guide rail, a load supporting deck disposed over the main body, and connecting members for interconnecting the main body and load supporting deck. The guide rail is enclosed in a tubular cover defining an opening extending longitudinally of the guide rail for receiving the connecting members. The cover has a substantially streamline configuration with respect to the direction of clean air flows.
