Title: Method for melting and refining superplastic alloy
Inventor: DEGAWA TORU
IPC: C22C1/02
Filed: 1986-04-14
Abstract: PURPOSE:To make the grains of a superplastic alloy fine in an industrially advantageous manner by melting and refining the alloy in a calcic refractory vessel under specified conditions. CONSTITUTION:A superplastic alloy is melted and refined in a vessel lined with a calcic refractory. At this time, the molten alloy is held at a temp. higher then the m.p. of the alloy by >=100 deg.C and/or under reduced pressure. Al and/or Ti can be added beforehand to the molten alloy. By this method, the calcic refractory is reduced by metals having an affinity for oxygen in the molten alloy, e.g., Al and Ti to leach Ca. This Ca is effective in making the resulting grains fine.

Filed: 1980-06-26
Abstract: PURPOSE:To shorten a time for information transfer, by constituting so that information of a desired extent can be directly transferred from one input/output device to the other input/output device, in case of information transfer. CONSTITUTION:In a central processing equipment CPU, information in a floppy disk FPD is read out by an input/output device I/O-1, and in case of instructing its transfer to a random access memory RAM of an input/output device I/O-2, a controlling circuit DMA-C of the I/O-1 receives only a start address of the FPD and a load start address of the I/O-2 from the CPU, and an address generation device I/O-AD sends out a load start address as an address of a register REG used by the I/O-2, but a socket of a data is fixed unti-information transfer is finished. Accordingly, when information is received and is written in the register REG, the I/O-2 sucks it up to the memory RAM immediately, therefore, the I/O-1 is able to send  out transfer information continuously.

Abstract: PURPOSE:To eliminat a malfunction against an hourly variation of a system by making a tone burst of an (n) wave having a different frequency correspond to a data of an (n) value, discriminating the data of an (n) value by a difference of frequency of the tone burst, and executing a reproducing. CONSTITUTION:Low band and high band tone oscillating parts 11, 12 always output a sine wave, and an output waveform is controlled by a data control part 14. The data control part 14 controls a changeover switch 13 so that a low band frequency fL and a high band frequency fH are obtained when a data is ''1'', and when the data is ''0'', respectively, and so that there is no tone when the data is ended. In a magnetic tape sound recording device 15, a data is sound-recorded by a signal format. A signal outputted from a magnetic tape reproducing device 21 is discriminated as to frequency by low band and high band passing filters 22, 23. A signal system of a mark signal 1 rectifies a level of a tone passing through the low band passing filter 22 by a level detector 24, outputs it from a level comparator 26, and a decoding system of a space signal ''0'' outputs the tone at an H level from a level comparator 27. A stop part becomes necessary for every 1-bit of the data, and sound recording and reproducing are executed without causing a malfunction.

Title: Connecting part structure of fluid route for automobile engine
Inventor: MATSUZAKI YOSHITOMI
IPC: F01P11/02
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To improve the safety of a connecting part, which includes a hose and a metal pipe, by passing the fluid of a high-pressure side to the safe direction when a connecting part is disconnected. SOLUTION: For example, a water passage changing part 4 is provided in an over-low connector 3 of a radiator 1. This water passage changing part 4 is formed by inclining an inner passage 3a of the over-flow connector 3 downward. This inclination is formed by a projecting part 5, which is formed by projecting an upper wall part 6 of the hover-flow connector 3 downward, and an inclined surface 6, which is formed by inclining a lower wall part 3c thereof downward. Consequently, in the case where a reserve hose is disconnected from the over-flow connector 3 by the fitting failure and deterioration of the reserve hose, the over-flowed cooling water is discharged downward like an arrow B.  Namely, since the over-flowed cooling water is securely discharged to a ground side different from the projecting direction of the over-flow connector 3, a danger that the over-flowed cooling water is spread on a person is reduced, and the safety can be improved.

Title: Clad material for lead frame
Inventor: KAWAKAMI MAKOTO
IPC: B32B15/01
Filed: 1990-03-30
Abstract: PURPOSE:To use easily and securely a Cu wire for bonding in assembly without using expensive Au or Ag spot plating by pressure welding at least one strip of stripe-shaped pure Cu foil having purity higher than specified with the specified thickness. CONSTITUTION:For good Cu wire bonding, pure Cu foil 2 with purity higher than 99.9% must be pressure welded to the required bonding area of a Cu-Fe alloy strip 1. Oxygen tree copper can be used for the high-purity Cu foil 2 and it must be 2-50mum thick after pressure welding because, if it is thinner than 2mum, additional elements diffuse from the Cu alloy strip 1 in heat treatment such as diffusion anneal and its bonding ability decreases and, if thicker than 50mum, the difference in strength between the foil and the Cu alloy strip 1 enlarges undesirably. The lead frame thus made has pure Cu only in the surface in the bonding area and Cu ball bonding can be performed easily and securely without expensive pre-treatment such as Au or Ag plating.
