Title: Board for chip mounting and manufacture thereof
Inventor: YOKOUCHI KISHIO
IPC: H05K1/14
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To facilitate manufacturing of a board for chip mounting that has a low coefficient of thermal expansion, high thermal conductivity and large size by employing as the material of the board a metal group composite material that has a metal of high thermal conductivity as matrix and contains a non-metal inorganic material having a small coefficient of thermal expansion in the matrix. SOLUTION: Binder resin and solvent are added to SiC particles 1a, 1b mixed in a rotary drum 2, and the materials are kneaded. The kneaded product is molded into a tape shape, and is cut to obtain square plate-like green sheets. The green sheets are fired in the air at 300 deg.C to form plate-like molded bodies 3. The molded bodies 3 are placed in a mold 5 made of graphite, and molten metal of Al-Si alloy at 700 deg.C is filled under pressure to impregnate the molded bodies 3 with Al-Si alloy. Warps and undulation in the metal group composite material 7 are removed by hot pressing 10 a nitrogen atmosphere at 600 deg.C to turn the metal group composite material into a flat board. The metal layer 6 is removed from the surface of the flat board.

Abstract: PURPOSE: To absorb and relax impact following a collision of a hand with a work bench by sliding of a base plate to prevent damage to the hand by allowing the base plate to be slidably and elastically in contact with a base body at the tip of an arm, and installing the hand in the base plate. CONSTITUTION: Even when a hand 17 at the tip of an arm 12 collides with a work bench (work bearer) 3 during operation, the impact force is absorbed and relaxed since a base plate 16 is slid into a base body 15. As a result, damage to the hand 17 is prevented. Further, sliding displacement of the base plate 16 is detected by means of a detector, and based on the detected sliding displacement, an origin-point of the hand 17 is automatically corrected by means of a correcting means, and thus the required operation is continued by the hand.

Filed: 1986-12-29
Abstract: PURPOSE:To inspect the surface unevenness of a specimen, by a method wherein the surface of the specimen is irradiated with the planar beam due to laser and a beam cutting image is picked up by a camera composed of an image sensor and a window is moved to an objective range to process the image in the window. CONSTITUTION:A beam projection apparatus 4 projects planar beam on a specimen 5 from the diagonally upward part of said specimen 5 and a camera 3 is arranged on the lateral side of the specimen 5. When the specimen is a proper product, a cutting-plane line 6A is generated on a solder built-up part 12 and, when the specimen 5 is an inferior product, a cutting-plane line 6B is generated on the end surface 13 of the specimen 5. The beam images 14A, 14B of the cutting-plane lines are stored in a memory 11 and a window 15 form observing a specific range by an operational controller is set at a predetermined position and the operational controller calculates the average brightness in the window and compares the same with a predetermined threshold value to judge the presence of a beam image. When the specimen is a good product, the beam image is raised by the built-up part 12 and the beam image 14A is not present in the window 12 and the average brightness becomes lower than the threshold value. By this constitution, soldering inferiority can be accurately detected and the extraction of the whole of the beam image or the analysis of a wave-form becomes unnecessary.

IPC: G01R31/26
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce a total height of an IC-testing apparatus and easily take out a test head, by moving a test tray in a vertical posture and bringing an IC to be tested into touch with the test head. SOLUTION: When an IC to be tested is loaded at a loader part (position C), a test tray TST is changed to a vertical posture by a first posture-changing means 310. The changed tray TST is moved downward, and inserted in a thermostatic chamber (position D), where a thermal stress is applied to the tray TST. Then, the tray TST is transferred to a test chamber (position E) by a belt transfer means 307. The tray TST still in the vertical posture is brought in touch with a test head 104, and the IC to be tested is tested. After the testing, the tray TST maintaining the vertical posture is carried to a heat removal chamber (position F). Since the tray TST is brought in touch with the test head 104 while maintained in the vertical posture, a transfer path for the tray TST can be close to a floor face, so that a height of the testing apparatus is decreased.

Title: Electronic balance
Inventor: SAKURA YASUHIRO
IPC: G01G23/37
Filed: 1991-11-28
Abstract: PURPOSE:To inexpensively reduce the weight measuring error of an electronic balance at its minimum scale switching point by averaging weight measuring errors over a whole weight measuring range. CONSTITUTION:A counter value obtained when no article is placed on a balance section 9 is stored in the area 3a of a RAM 3 and the counter value obtained when the maximum weight is measured is stored in the area 3b of the RAM 3. In addition, the counter value corresponding to the weight at which the minimum scale is switched is stored in the area 3c of the RAM 3. The weight measuring error of a switched weight is calculated by calculating a theoretical count value zero-corrected for the switched weight from the counter values stored in the areas 3b and 3c and subtracting an actually measured value. Then an assumed error at the maximum weight is calculated by multiplying the calculated weight measuring error by the ratio of the maximum weight to the switching weight and a corrected span value is calculated by adding 50% of the count value to the difference between the counter values stored in the areas 3b and 3a. The corrected span value is stored in the area 3b of the RAM 3. A CPU 1 converts data converted by means of an A/D converter 10 into a weight based on the corrected span value and counter value (at zero point) stored in the area 3a.
