Filed: 1990-08-28
Abstract: PURPOSE:To send a parallel data without losing the transmission efficiency by providing a delay time measuring means measuring a delay time from a bit delayed most for each bit and a delay means delaying plural bits respectively by each delay time and outputting the result to the circuit. CONSTITUTION:A phase correction circuit 100 consists of an inverter 101, a D flip-flop 1 connecting to the inverter 101, a counter 2 connecting to a Q output of the D-F/F1, a delay circuit 6 and a selector 7. Moreover, a data transmission circuit is provided with an AND circuit 4 receiving the Q output of the D-F/F1 of each of phase correction circuits 100-400 and an OR circuit 5 connecting to a clock generator 3 and the AND circuit 4. Then the delay time among input bits A-D is measured and the input bits A-D are delayed respectively only the measured delay time. Thus, output bits A-D are a transmission data without a phase difference. Thus, the parallel data transmission for a long distance is attained and the transmission efficiency is enhanced.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a cutting work due to formation of a recessed part and a protrusion part when the element of a belt for a continuously variable transmission having a recessed part and a protrusion part is manufactured. SOLUTION: An element is a plurality of elements laminated together in the direction of a sheet to form an annular belt for a continuously variable transmission and provided with a recessed part 21, a protrusion part 22, and a hole 23 formed on one side in the direction of a sheet thickness. The protrusion part 22 is formed on the other side in the direction of a sheet thickness and engaged with the recessed part 21 of an adjoining element 20. The hole 23 is formed in the protrusion part 22. The recessed part 21 and the protrusion part 22 are simultaneously formed by a press work. A hole 23a being the origin of the hole 23 is formed at a process followed by a press work to simultaneously mold the recessed part 21 and the protrusion part 22. The volume of the internal space of the recessed part 21 is larger than that of the protrusion part 22.  The internal volume of the hole 23a before a press work is larger than a difference between the volume of the internal space of the recessed part 21 and the volume of the protrusion part 22 containing the hole 23.

Title: Ceramic ball grid array using on-site extension of solder
Inventor: PETER J BROFMAN
IPC: H05K3/34
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To form an extended solder bond between two electronic substrates which are mutually connected by the solder to form an electronic module, by heating the two substrates, imparting controlled separating force to the solder bond plasticized by the heat between the substrates, extending the solder bond, and refrigerating the resultant module to set the extended solder bond. SOLUTION: Solder bonds 12 having a height S are generally used for treating a printed circuit board or the like, i.e., a substrate 11, which is connected to a chip, i.e., a substrate 13. Specifically, the solder bonds 12 are formed between these two electronic substrates 11, 13 to form a mutually connected electronic module. Thereafter, the module is heated to plasticize the solder bonds 12. Subsequently, separating power is imparted to the two electronic substrates 11, 13 so as to extend the plasticized solder bonds 12, thereby forming an extended solder bond. Then, the module thus extended is refrigerated to complete the electronic module comprising the extended solder bond.

IPC: B24B37/30
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of micro-crushing of an edge part of a work body by providing a recessed groove part on an inner peripheral surface edge part of a retainer constituting a one side working machine to machine the plate type work body by adsorbing and fixing it. SOLUTION: A surface plate 2 is rotated and an upper part pressure plate 4 moves its position on the surface plate 2 around a support point 6 as its center by a support arm 5 at the time of machining. At this time, working liquid containing an abrasive material is supplied onto a working surface from a nozzle. Machining proceeds by pressure force by the pressure plate 4 and rotational work of the surface plate 2, but a side surface of a work body 10 of glass, etc., slightly rattles in a holding hole of a retainer 15 and makes contact with an inner peripheral edge part. At this time, an edge part 13 of the work body 10 makes contact with a recessed groove 17 engraved on an edge part of the retainer 15.  That is, there is nothing with which the edge part substantially makes contact and contact with the edge part and impact are avoided, and accordingly, micro-crushing never occurs on the edge part.

IPC: B01D53/12
Filed: 1992-08-27
Abstract: PURPOSE:To decrease fluctuation in the amount of an exhaust gas fed in an adsorption tower and to make movement of a granulated active carbon on an air-permeable panel smooth by connecting a chamber wherein a gas can be stored with a duct and connecting another end of a reflux duct one end of which is connected with a discharging hole of a purified gas of the adsorption tower with the chamber. CONSTITUTION:A chamber 31 wherein gas can be stored is connected with the intermediate part of a duct 22 connecting the first air blower 21 with the second air blower 23 and it is also connected with another end of a reflux duct 25 connected with one end of a discharging hole 24d of a purified gas of an adsorption layer 24. Therefore, even when the amt. of discharge of an exhaust gas 11 from an exhaust gas generating source is fluctuated, as the fluctuation is reluxed in the chamber 31, the amt. of the exhaust gas 11 (in more detailed description, the exhaust gas 11+ the purified gas 12) fed in the adsorption tower 24 is stabilized. In addition, fluctuation of the inner pressure is made milder as the vol. of the chamber 31 increases and the vol. is determined by the discharging speed and its fluctuation of the exhaust gas 11 and the space of installation.

Abstract: PURPOSE:To strengthen joint further and to carry out a continuous hot rolling high in productivity by partially joining a preceding and a succeeding steel materials at first on the inlet side of rolling installation and contact-joining the tip part of the billet all over the width at the stage of finish rolling. CONSTITUTION:After the heel part of the preceding steel billet 1 and the tip part of the succeeding steel billet 2 are cut respectively in a flat shape, upsetting is performed in the middle area excepting both end areas of each billet 1, 2 so as to produce a specified interval in the abut contact state of two billets. After both steel billets are abutted, heating and pressing are executed. As a result, deformation begins from both end areas being high temperature parts, the joining area expands gradually from both end areas to the central area and the joining strength is solidified efficiently. Consequently, the joined part of the steel billet during rolling is not broken and separated and can be rolled stably.
