Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide distortion suppression quantity more than a specified value while attaining miniaturization by providing a filter inside a distortion detection loop or a distortion removal loop and parallelly setting plural filters to a signal line. SOLUTION: An output from a signal synthesizing part 7 is amplified through a vector adjuster 8 of a distortion detection loop through an auxiliary amplifier 9 while being mainly occupied with distortion quantity at a main amplifier 4. When the main amplifier 4 applies a high output such as 43dBm, plural filters 6 are parallelly inserted so that the characteristics of its frequency, phase and amplitude can become inverted in phase, and flattening in the phase and amplitude characteristics is attained to the frequency. On the other hand, the signal from the main amplifier 4 is transmitted through a directional coupler 5 and a filter 11 of a distortion removal loop to the signal synthesizing part of the directional coupler 12.  At such a time, the plural filters 11 inverted in phase and amplitude characteristics are parallelly inserted so as to cancel the frequency characteristics of the auxiliary amplifier 9, the phase and amplitude characteristics are flattened and the distortion suppressing quantity more than 40dB can be secured.

A pulse code modulation(PCM) and pulse width modulation(PWM) converter 33 is the PCM PWM converter of a front edge-type, a trailing edge-type and a symmetrical type. The scaled clock signal is generated, based on the PCM signal of N-bit and the PCM signal of the most significant k-bit in the PCM signal of N-bit and converts the signal of the most significant into a PWM output signal, based on the clock signal.

IPC: H01J37/317
Filed: 1982-01-18
Abstract: PURPOSE:To prevent a specimen base from being melted, by a method wherein a supporting member of the specimen base is made of material being different from a specimen plate in reflection coefficient, and beam is irradiated only to the specimen plate. CONSTITUTION:A specimen base 7 is made of Al or the like, and a supporting member 9 on which a wafer 5 is directly held is made of metal having high melting point. A detector 10 for detecting a reflection beam 12 is installed near a deflecting member 6. When the scanning by the deflecting member comes to narrow region including end portion of the wafer 5 and outside portion of the wafer 5, the detector 10 detects that intensity of reflected beam 12 of irradiated electron beam is different between the wafer 5 and the metal supporting member 9. Based on this information, a generating member 1 stops the beam generation and a drive unit 8 moves the specimen base. As a result, the specimen base needs not be made of expensive material and even when the specimen plate is changed in size or the like, detection is performed automatically.

Filed: 1990-01-17
Abstract: PURPOSE:To assure collection of refrigerant and to prevent degradation of compressor due to vacuum operation by a method wherein finish of refrigerant collecting operation carried out at the start of air warming operation is decided on the base of detection signal provided from a current detector which detects current flowing in the compressor. CONSTITUTION:A current detector 10 detects current flowing from a power source 12 to a compressor 1 and provides detection signal to a controller 11 to control the operation of the compressor 1 on the base of the signal. When a refrigerant collecting operation starts, the current in the compressor 1 rises up once and then drops down gradually. After the refrigerant collecting operation finishes, as the compressor 1 is unloaded, its current continuous substantially constant because of unloaded operation. In this constitution, this constant current is detected, and the detection means the finish of the refrigerant collecting operation. Thus the refrigerant collection can be assured and its operation can be minimized, and, as a consequence, the duration of the compressor 1 can be lengthened.

Abstract: PURPOSE:To enable a discharge between first and second surface electrodes to be suppressed and popcorn noise to be reduced by positioning the three sides of each electrode except two opposing sides at prescribed spacings from the outer peripheral ends of the surface of a pellet. CONSTITUTION:When a person passes the front of a pellet 1 in a direction shown by an arrow A, infrared rays from the human body are incident upon an electrode 3a side and the amount of charge in the portion of the pellet 1 just under the electrode 3a is changed (for example, decreased). Negative charge on the electrode 3a becomes movable and, in this case, negative charge on an electrode 3b becomes immovable. Therefore, signals in accordance with difference between movable charges on both the electrodes 3a and 3b are led out outside from leadout wires 5a and 5b. Then, when infrared rays are incident upon the portion of the pellet 1 on the electrode 3b side, the amount of charge in the portion of the pellet 1 just under the electrode 3b is changed and the amount of charge in the portion of the pellet 1 just under the electrode 3a is also changed because infrared rays are not incident. Accordingly, signals in accordance with difference between the movable charges on both the electrodes are led out from the leadout wires 5a and 5b to emit an intrusion alarm.
