  • Publication number: 20100000235
    Abstract: A cryopump includes a radiation shield provided with a main inlet at one end thereof and a sub-inlet in a side thereof; and a cryopanel assembly cooled to a temperature lower than that of the radiation shield. The cryopanel assembly includes an upper structure having at least one cryopanel and a lower structure having at least one cryopanel. The upper and lower structures are arranged inside the radiation shield along a direction away from the main inlet. A frost accommodating space connected to the sub-inlet may be arranged between the upper and lower structures such that an amount of captured gas on an upper end cryopanel of the lower structure is greater than an amount of captured gas on a lower end cryopanel of the upper structure.

  • Patent number: 7555911
    Abstract: An inverter (22) is provided between a power source (20) and a suction/discharge valve driving motor (14) that controls cycle time of suction and discharge of a refrigerator unit (10). An output frequency of the inverter (22) is controlled in accordance with output of a sensor (24) that detects temperature of a thermal load portion (11) of the refrigerator unit (10). This enables temperature adjustment of individual refrigerators with a highly reliable method without using an electric heater.

  • Patent number: 7480390
    Abstract: The present invention provides a loudspeaker including an edge formed in such manner that a thickness of a sectional shape in a radial direction increases from an inner peripheral portion toward an outer peripheral portion. Due to this structure, a mechanical impedance of the edge against a diaphragm is decreased and bad influences on a vibration mode of the diaphragm are suppressed, and also, vibration energy is absorbed by a thick portion of the outer peripheral portion, thereby suppressing standing waves of the diaphragm.

  • Patent number: 7468282
    Abstract: A pin junction element includes a ferromagnetic p-type semiconductor layer and a n-type semiconductor layer which are connected via an insulating layer, and which shows a tunneling magnetic resistance according to the magnetization of the ferromagnetic p-type semiconductor layer and the magnetization of the ferromagnetic n-type semiconductor layer. In this pin junction element, an empty layer is formed with an applied bias, thereby generating tunnel current via an empty layer. As a result, it is possible to generate tunnel current even when adopting a thicker insulating layer than that of the conventional tunnel magnetic resistance element.

  • Patent number: 7136495
    Abstract: A loudspeaker device comprising a power amplifier (13) to which an input signal is delivered via a subtracter (6), a speaker unit (1) for reproducing output signals delivered from the power amplifier (13), an acoustic pipe (2) coupled in front of the speaker unit for guiding the sound waves, a microphone (4) for detecting an acoustic outputs radiated from the speaker unit, a microphone amplifier (5) for amplifying an acoustic output signals detected by the microphone, and a negative feedback circuit. Output signals of the microphone amplifier are delivered to the subtracter, at the same time the same output signal is connected to a high-pass filter (7) to be delivered to the subtracter. Thus the negative feedback circuit is formed to suppress peaks and dips for providing a flattened sound pressure frequency characteristic.
