Title: Error correcting system
Inventor: FUJIWARA TOSHIYUKI
IPC: H04J1/02
Filed: 1980-06-09
Abstract: PURPOSE:To correct the error due to fading and radio interference normally in an FDM system, by frequency-dividing transmission data, transmitting it >=3 times by shifting time and modulated frequency, and discriminating it by majority decision at demodulation at reception side. CONSTITUTION:Transmission data is frequency-divided at transmission side each subchannel, the data is transmitted >=3 times by shifting time and modulation frequency without duplication, it is demodulated at the reception side and correct data is obtained by a majority decision method. For example, a serial digital data as shown in Figure, is fed to a code converter, where serial-parallel conversion is made to form the data as shown in Figure, and further it is fed to an FDM modulator and then transmitted by modulating it by PSK etc. At the reception side, this signal is demodulated at an FDM demodulator to reproduce the original data, and this is applied to a majority decision discriminator, and if the transmission data is transmitted consecutively 3 times, when the data of twice or more is correct, this is outputted as a correct data.

IPC: H05K3/34
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of voids when a soldering section between a BGA(ball grid array) and a printed wiring board is filled with an insulating resin. SOLUTION: On the lower surface of a BGA or FPBGA(ball grid array or fine-pitch ball grid array), four grooves 1 are arranged in a grid-like state. Each groove 1 is formed between arrays of bumps 2 and the width and depth of the groove 1 are adjusted so that the groove 1 may not deteriorate the function of the BGA or FPBGA. At the time of injecting an insulating resin 8 into a soldering section, the resin 8 is injected from a certain side of the BGA or FPBGA. Of the injected resin 8, the part which gets in the grooves 1 flows in the grooves 1 as shown by the arrows A prior to the part which gets in the other section than the grooves 1 due to a capillary action and the part which gets in the other section than the grooves 1 flows in the directions shown by the arrows B and spreads around the bumps 2.

Title: Manufacture of lead frame
Inventor: KAWAMURA TOSHIO
IPC: H01L23/50
Filed: 1991-04-10
Abstract: PURPOSE:To provide a method for manufacturing a fine lead frame. CONSTITUTION:When lead frame for IC with a dam bar 1 and a tie bar 2 an manufactured, a lead frame with an expansion and contraction portion 3 where a lead interval can be expanded and contracted is produced at the above dam bar and the tie bar portions while the expansion and contraction portion is expanded, and the above expansion and contraction portion is reduced, thus enabling the above expansion and contraction portion to be reduced and hence enabling a lead tip portion 4 to be highly dense. Since an extraction width dimension can be increased for a completion dimension for a punch and a die, they are less restricted by punch strength and machining dimensions, thus achieving highly accurate machining with a conventional technology (1). By controlling an amount of expansion and contraction, a lead frame with a lead interval matching the chip size can be produced (2). A structure of mold can be simplified since press machining can be made with the lead interval being wide.

Title: Method for recycling activated beryllium
Inventor: KAWAMURA HIROSHI
IPC: B09B5/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To remove oxides or activated impurities from the spent activated beryllium which is activated by neutron emission, recover beryllium and recycle it. SOLUTION: Either one halogen gas selected from the group of chlorine, bromine and iodine is used to make activated beryllium into beryllium halide, whereby a high purity beryllium halide is recovered as gas at a temperature of the natural sublimating temperature or more. In order to suppress the reaction of an oxide such as beryllium oxide or a radioactive impurity such as Co-60 with a halogen, the reaction temperature is set to a temperature higher by 100 deg.C than the sublimating temperature of the beryllium halide. Then, the recovered high purity beryllium halide is thermally decomposed to recover metal beryllium. In this case, when the beryllium halide is preliminarily reduced with a silane gas represented by Sin H2n+2 to make the beryllium halide non- sublimatable, and then thermally decomposed, the yield of metal beryllium is increased.

IPC: G01S7/527
Filed: 1980-06-12
Abstract: PURPOSE:To prevent erroneous operation due to noises by transmitting two-phase ultrasonic wave having specified phases, and comparing the phase difference between the transmitted and reflected waves. CONSTITUTION:Two-phase pulses (b), which have a pulse width t, a period To, and phase difference t1, are transmitted from an ultrasonic wave transmitter 1. The phase difference t2 between two phases is detected (e) in a flip-flop 14 using the received signal c which is the reflected signal. Said phase difference t2 and the phase difference t1 obtained from a monostable multivibrator 16 are compared in a compared in a comparator 17. If the phase differences are equal with each other, a switch circuit 20 is opened, a pulse is fed to a measuring circuit 10 from a counting pulse oscillator 19 via a pulse gate circuit 9 and counting is performed. If the phase differences are not equal with each other, the presence of the noise is recognized,  the switch 20 is closed, and the passage of the pulse to the measuring circuit 10 is  blocked. Thus the erroneous operation due to the noises can be prevented.

Abstract: PURPOSE:To restrain deflection of a flexible membrane to improve durability of the membrane and improve compression and discharge performance of a compression device by providing a back pressure chamber divided from a compression chamber with the flexible membrane and having half of pressure in the compression chamber at compression in a casing. CONSTITUTION:A flexible membrane, namely, a diaphragm 15 is received in a casing 2 composed of a case 1 and a valve case 26.
