Title: Circuit borad composition
Inventor: SHIMADA YOSHIHIRO
IPC: H01L23/498
Filed: 1981-05-19
Abstract: PURPOSE:To obtain a low cost circuit mounting composition by applying gold and tin alloy plating on the whole surface including IC connection fingers and electrodes for connection to indication elements. CONSTITUTION:A gold and tin alloy film 5 is formed on the surface of a copper foil pattern 4 on a circuit board 1 by a plating bath. Gold bumps 7 on an IC3 and fingers 4a are heated and compressed, so that the gold and tin alloy 5 is diffused into the gold bumps 7 and strong junction can be obtained. As the surfaces of connecting electrodes 4b are also covered by the gold and tin alloy 5, the electrodes 4b have good solderability and their contact condition is stabilized. With this constitution, plating with high productivity and high quality can be obtained and the IC can be mounted with high yield.

Title: Laminated sheet having diving marks, and apparatus for detecting the dicing marks of the laminated sheet
Inventor: INAI MASAYUKI
IPC: H01L21/301
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a laminated sheet capable of accurately detecting dicing marks. SOLUTION: A straight line groove 2a, having a U-shaped transverse section is formed along each of the four sides of an upper face of a laminated sheet 1, and a dicing mark 3a is constituted of an array of a plurality of mark pattern ends exposed to an inner face of the groove 2a. Since the width of the mark pattern end exposed to the inner face of the groove incrementally increases toward groove bottom, the dicing mark 3a can be made clearer. Therefore, even if the image of the dicing mark 3a is picked up by the camera of an image processor, detection of the dicing mark 3a is readily effected and accuracy in detecting the mark is also improved.

IPC: H01K3/00
Filed: 1981-05-20
Abstract: PURPOSE: To perform a measurement of sealed gas pressure, by a method wherein a computing formula, having a proportional constant being common to lamps of the same type, is set, and through projection of coherent light at each lamp, a measurement is made on the second of an interference fringe representing a change in a photo path length produced after lighting has elapsed from a non- lighting time of a lamp serving as a reference.  
     CONSTITUTION: Provided a refractory rate at a normal temperature of a pressure p o , in which sealing gas exists, is set to a known n o , a relation of mλp o = pηl(n o -1) is recognized between a sealing pressure P and a second degree m of an interference fringe, and thereby, a proportional constant η, being common to lamps of the same type, is previously found. Laser light 2 is then focused on a lamp 20 placed on an optical path 8a between a first semiclear mirror 4 and a reflecting mirror 5, and based on the length of the optical path at a normal temperature (non-lighting) of two optical paths 8a and 8b, a change in the optical path length, produced after t-second has elapsed from a point of time when a heating substance 21 lights on, is caught as the second degree of the interference fringe, and from the second degree m of the inteference fringe, the sealing gas pressure P at the normal temperature is found by an arithmetic unit 18.

Filed: 1979-06-13
Abstract: PURPOSE: To prevent interlocking members from colliding with each other and also to decrease noises by preventing rotations according to inertia force of a rotary shaft of a starting motor for a plunging starter.  
     CONSTITUTION: From turning a starting switch on, an electromagnet 58 attracts a pressure plate 50 rightward against a spring 52 to detach it from a friction plate 46. A starting motor 10 is then driven simultaneously, and rotations of its output shaft 16 are transferred to an interlocking member 32 through a gear 16 and a reduction mechanism 12. Then the interlocking member 32 moves rightward to engage with an interlocking member 28, and thus a crankshaft 14 is rotated. When the starting switch is turned off after that, the plate 50 is left free, pressed leftward by the spring 52 and then interlocked with the friction plate 46, thus stopping the rotary shaft 16 quickly according to a friction force working then.

Title: Lubricating oil control ring for piston of internal combustion engine
Inventor: YAMAMOTO OSAMI
IPC: F16J9/20
Filed: 1981-05-18
Abstract: PURPOSE: To control the lubricating oil failed to be scraped off and to prevent the burning of the skirt of the piston of the internal combustion engine by a method wherein a ring groove is formed in the lower end of the piston and a piston ring having no gap between its fitting sections and having no oil hole or groove is fitted in the ring groove.  
     CONSTITUTION: In a burning preventive structure for the piston 2 of the internal combustion engine, a crankcase oil splashed upon a cylinder liner 3 by a crank is utilized to lubricate the skirt 8 of the piston. In case where the quantity of such oil is too large, the ring groove is formed in the lowermost end of the piston 2 and the lubricating oil control ring 7 is fitted in the groove to thereby control the oil. In this case, the ring 7 is usually made in the form of the piston ring and to have no gap between the fitting sections 7a and 7b thereof. In other words, as will be understood from Fig. (a) and Fig. (b) showing the conditions of the fitting sections 7a and 7b of the ring 7 prior to their fitting into the ring groove, the section 7a and 7b are so formed that the gap between the them becomes zero when they are fitted in the ring groove.

Title: Plate passing speed control method in tandem rolling mill
Inventor: AOKI SHIGEO
IPC: B21B37/00
Filed: 1978-06-21
Abstract: PURPOSE: To prevent the breakage phenomenon at the biting of the leading end and roll mark flaws by making the work roll revolving speed of each stand substantially lower than the steady plate passing speed before the material to be rolled bites into the stand and make it higher than the steady speed until the material bites into the stand of the next stage after the biting and returning it to the steady speed after biting into the stand of the next stage.  
     CONSTITUTION: Before the material to be rolled 24 reaches the first stand 18a, the work roll revolving speed of each stand is subjected to controlling of number of revolutions. When it is detected that the leading end of the material to be rolled 24 reaches the first stand and bites into the work roll 14, the work roll revolving speed of the first stand 18a is increased. When the leading end of the material to be rolled 24 reaches the second stand 18b, the work roll revolving speed of 18a is decreased and the work roll revolving speed of the second stand increased. Since the speeds are lower and higher than those of conventional steady plate pass speeds, the tension between the first and second stand becomes smaller.
