摘要:
A micro terminal for inspection or installation with high connection reliability is provided at lower cost. A micro terminal according to the present invention has electrical conduction between the micro terminal and an electrode of an electronic device or an inspection device and includes a columnar contactor in contact with the electrode. The contactor has a spring structure which is elastically deformed when pressed against the electrode. The contactor includes a protrusion protruding outwardly at its end in contact with the electrode and the shape of the protrusion has a part of a sphere or a part of a paraboloid of revolution.

Disclosed is a technique for reducing noise superimposed on an output signal while keeping loop gain constant without increasing the circuit scale and without changing the transfer function of the amplifier apparatus (frequency characteristics of gain and phase). According to the technique, there are included a power-supply voltage control unit 7 for detecting the amplitude level S9 of an input audio signal S1 and outputting power with a voltage value indicated by target set voltage value information Vs corresponding to this amplitude level S9, and a PWM modulation unit 2 including a PWM converter 23 for converting the pulse width of the input audio signal S1 and a correction unit for correcting the signal modulated by the PWM converter 23. The PWM modulation unit 2 corrects the pulse width of a PWM signal S5 modulated by the PWM converter 23 so that the correction unit will cancel out a change in amplification gain of a power amplification unit 4 according to the target set voltage value information Vs.
摘要:
A contact probe is fabricated by forming a resin mold with a cavity on a substrate having conductivity, and filling the cavity with metal through electroforming. The metal includes a cobalt-tungsten alloy. Alternatively, a cobalt-molybdenum alloy may be used instead of the cobalt-tungsten alloy. Alternatively, a contact probe can be made from nickel, cobalt or copper, and have a coat film of cobalt-tungsten alloy or cobalt-molybdenum alloy formed thereon to increase the abrasion resistance. A nickel-molybdenum alloy can be used instead of the cobalt-tungsten alloy or cobalt-molybdenum alloy.

摘要:
An electronic stringed instrument is provided where the value of a pitch that has been currently detected and the value of a pitch that has been stored are compared. A determination is made as to whether or not the pitch has dropped roughly a half tone. In those cases where the currently detected pitch has dropped roughly a half tone from the pitch detected a specified period earlier, a tone generator begins the attenuation of a musical tone that is generated and the note height of the musical tone is controlled so that the note height does not change.
