Abstract: PROBLEM TO BE SOLVED: To bring an IC in a uniform contact with contact pins by providing a presser part pressing the IC mounted on the contact pins, an energizing means energizing an upper block arranged vertically movably in such a direction as separating the upper block vertically, and a magnet attracting in an approaching direction. SOLUTION: When an IC 2 is tested, an upper block 22 is pressed down by a press-down means 4 so that a press-down rod member 34 is pressed down. A stopper 35 of a rod member 34 compresses a spring 23 and an abutment member 26 of a lower block 27 of the presser means 21 pressurizes the IC 2 toward contact pins 13 at a prescribed energizing force. The respective terminals of the IC 2 and a test board 3 are thus brought in contact with each other via the contact pins 13. Where the dimensional tolerance of the IC 2 is small, the contact face of the respective springs 23 with the lower block 27 becomes approximately horizontal so that the compression quantities of the respective springs 23 become almost same and their energizing forces become the same. Their intervals to respective magnets 24a, 24b become same so that the attraction forces become same.  The respective terminals of the IC 2 are uniformly pressed by the contact pins 13.

IPC: H04N5/335
Filed: 1988-06-15
Abstract: PURPOSE:To attain high speed drive with low voltage, low power consumption and excellent start characteristic even with a high definition CCD whose drive frequency is high by making a bipolar transistor(TR) in standby at the off-state during transistor stop period in a drive circuit employing the bipolar TR as a switching element. CONSTITUTION:Variable inductances L1, L2 are resonated by an electrode capacitance at a drive frequency in a switching resonance drive circuit of biphase drive CCD. A 1st phase drive input signal VB1 is converted to a level proper to drive a base of a switching Tr1 by bias resistors 7, 8 and a capacitor 6 and the Tr1 repeats ON/OFF operation. The electromagnetic energy stored once in the inductance is transferred to the transfer electrode capacitance as the electrostatic energy and the result appears at the transfer electrode as a sinusoidal voltage. Since the Tr1 is in standby with off state during the transfer stop period, no carrier exists in the base-collector junction region and the on-operation is started momentarily at the starting period from the transfer stop period to the transfer start period.

Title: Evaluation method of film quality for insulation film
Inventor: NISHIOKA SUNAO
IPC: G01N21/956
Filed: 1977-12-06
Abstract: PURPOSE: To evaluate the film quality by changing the strength of electric field applied to the insulation film, through the application of dynamic scattering phenomenon of nematic liquid crystal.  
     CONSTITUTION: The test piece 100 has the SiO 2  film 2 including defects 3 on the substrate 1. The Al electrode 4 is formed on the film 2, nematic liquid crystal film 5 is coated, and the transparent conductive film 6 coated on the glass plate 7 is laminated. The insulation spacer 8 is inserted between the Al elctrode around the test piece and the conductive film 6.
