Abstract: PURPOSE:To continue bonding work by a method wherein paste deposited on the side wall of a nozzle supporting the paste is removed with a cleaner before bonding a semiconductor element or wires to electrodes by interposing paste or a viscous substance. CONSTITUTION:A mount 5 with many thick film circuits 1 is carried into place by means of two carrier belts 3 and 4, and IC elements 2 are die bonded to the circuits 1 by being held with a hold lid 8 having holes 9 appointing bonding regions. In this construction, at the same time with the stop of the mount 5, a die-bonding position is fixed by a position recognizer 10, and a dispense nozzle 12 projecting downward out of the device 10 is lowered and made to spout the paste, resulting in die bonding.

Title: Adhesive strength measuring method for laminated substrate
Inventor: SUGIMOTO FUMITOSHI
IPC: G01N19/04
Filed: 1990-04-03
Abstract: PURPOSE:To obtain a measured value which is close to a real value by making the adhesion surface area of one measuring jig smaller than the area of a sample made of the laminated substrate and applying a tensile force until a blank material where a small measuring jig is adhered breaks. CONSTITUTION:The measuring jigs 5 and 6 are adhered to both surfaces of the sample 3 to be measured which consists of the laminated substrate having a layer 11 interposed between blank plates 1 and 2. The surface of the measuring jig 5 which is adhered to the sample 3 to be measured is smaller than the sample 3 to be measured. In this state, the sample 3 is applied with the vertical tensile force until the blank plate 2 breaks to separate from the blank plate 1. The blank plate 2 is ground thinnly (to about 100 mum) and breaks with a small force. The force required to cause the blank plate 2 to break can be calculated or obtained by a general tension test, so the force required for the breakage of the blank plate 2 is subtracted from tensile strength obtained by measurement to calculate only the adhesive strength of the laminated substrate.

As for the similarity, the posterior probability is a measure, and the occurrence of each word is an independent event, therefore, the mutual comparison can be executed, and the comparison can be executed by the sum of the similarity of words of the first half and the latter half. By dividing a store dictionary in a word dictionary memory 3 into each item, the processing time of a similarity arithmetic part 2 can be curtailed, comparing with the case of one kind of word dictionary. Also, since the correspondence of the words of the first half and the latter half can be decided by a word dictionary correspondence table 7, the candidates can be reduced and an erroneous combination can be eliminated. In such a way, the reliability of a result of recognition is raised.

Title: Method of preventing vaporization of liquefied gas and liquefied gas tank
Inventor: FURUHAMA SHIYOUICHI
IPC: F25J1/00
Filed: 1979-07-16
Abstract: PURPOSE:To cool gas evaporated in a tank and liquefy the gas again, by vaporizing pressurized liquefied gas in a gas layer in the tank with a heat exchanger and jetting the vaporized gas into the gas layer. CONSTITUTION:Liquefied gas in a liquefied gas tank 2 is pressurized by a liquefied gas booster pump 4, and a heat exchange is performed between said pressurized liquefied gas and vaporized gas by a heat exchanger 6 in a gas layer 5 within the tank 2. In this way, the vaporized gas can be cooled while the pressurized liquefied gas is vaporized to become high pressure gas. And then the high pressure gas vaporized from the pressurized liquefied gas is jetted into the gas layer 5. Such a jetting operation as described causes the Joule-Thomson effect by which the temperature of jetted gas lowers to liquefy the gas simultaneously with a peripheral gas, which has been vaporized, is liquefied. In such means as performed, a vaporization in the tank 2 can be prevented to avoid its abnormal temperature rise, thus to eliminate a loss of energy.
