Inventor: ADACHI JUNJI
IPC: G01R1/067
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a probe needle, a probe card and manufacture of the probe needle which are excellent in contact, strength and durability. SOLUTION: This probe needle 1 has the dual structure of an inner needle material 3 and an outer needle material 4 covering its periphery. The inner needle material 3 is formed by VIII metal or IB metal, while the outer needle material 4 is formed by VIB metal, VIB metal or VIIB metal. The outer needle material 4 from the tip end of the probe needle 1 to a predetermined length is eliminated by chemical treatment so as to expose the inner needle material 3. As the inner needle material 3 is excellent in contact, a contact resistance at the time of contact with an article to be tested becomes low, and the accuracy becomes high accordingly. The inner needle material 3 protected by the outer needle material 4 with excellent strength and durability is excellent in strength and durability.  If a dummy needle for eliminating impurity is provided beside a test needle, real electric characteristics of the article to be tested can be tested, and test accuracy is improved.

Title: Two color electrophotographic copying method
Inventor: SAKAI TOSHIO
IPC: G03G15/01
Filed: 1978-11-28
Abstract: PURPOSE: To obtain good copied images of two colors by providing two layers of photoconductive  layers of a layer having photosensitivity to two colors of light and a layer having no photosensitivity thereto to a photoreceptor, insulating these two layers, performing the specified photosensitive  operations and using two kinds of the toners having been charged to mutually opposite polarities.   
     CONSTITUTION: A photoreceptor 1 is made by laminating the first photoconductive layer 12,  transparent insulation layer 13, second photoconductive layer 14 and transparent insulation layer  15 on a conductive substrate 11. While the first photoconductive layer 12 has photosensitivity to  A-color light, the second photoconductive layer 14 is insensitive to the A-color light. First, the  photoreceptor 1 is radiated with white color light then with A-color light, and this enables the  polarities such as the illustrated ones to be obtained in the photoconductive layers 12, 14, but the  photoreceptor surface is destaticized next by being subjected to positive corona discharging in the  dark by a charger 4. Next, the light images of the original 0 are exposed to the photoreceptor 1.  Since white ground part OW, black color image OB and A-color image OA are stated on the  original 0, the electrostatic latent images are visualized by the negatively charged black color  toner and the positively charged A-color toner to obtain the TB image and TA image, which are  then combined with the white color part, whereby the visible copied images of the two colors are  obtainable.

Title: Link amplifier
Inventor: TAKAI HITOSHI
IPC: H04N7/16
Filed: 1985-07-04
Abstract: PURPOSE:To reduce distortion trouble by taking out cross modulation components from a TV signal to a pilot signal through a filter which allows the above components to pass a horizontal scanning frequency of the TV signal and integer multiple of the above frequency and also lowering the amplification degree at levels. CONSTITUTION:Signals included by the TV signal and non-modulated pilot signal enter in an input terminal 1 and is amplified by a line amplifier 8. The pilot signal receiving cross modulation is extracted by the first filter 18 and is amplified by a pilot signal amplifier 19 then envelope lines can be taken out after being detected by a detector 20. An output of the detector 20 permits one or plural components among frequency components of the horizontal scanning frequency and integer multiple of the frequency to pass the second filter 9 then develops detecting signals. The second filter 9 allows S/N of the detecting signals to improve. The detected signals are amplified by a detection amplifier 10 and detected signal levels are detected by a level detector 11. If the detecting signal levels go to abnormally hi the distortion is lightened by lowering amplification degree of the line amplifier 8.
