Title: Shift mechanism of transmission
Inventor: OKADA MITSUHIKO
IPC: G05G9/08
Filed: 1983-05-02
Abstract: PURPOSE:To attain a compact shift mechanism of a transmission by attaching a shift shaft and a shift head so that they can move in body only in a fixed range. CONSTITUTION:When a shift lever 75 is set at a neutral position, a shift head 51, a counter rod 53 and a counter lever 55 are unified so that they can have no link action. When the lever 75 is set at position D, only a shift head 50 moves to the left side. Thus a reverse driven gear moves left via a shift fork and engages a forward driven gear. When the lever 75 is set at position R, only the head 50 moves right. Then the reverse driven gear moves via the shift fork and engages a reverse intermediate gear. When the lever 75 is set at position P, the heads 51 and 50 move right and left respectively. Thus the reverse driven gear engages a parking gear.

Title: Fuse
Inventor: HANAZAKI HISASHI
IPC: H01H85/56
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To eliminate dispersion in fusion characteristics and provide stable fuse characteristics by a locking a low-melting point metal lump by surrounding it around a fuse element and providing an alloy layer so as to be equally generated at each part of the fuse element. SOLUTION: A fuse 21 is locked to a fuse element 26 with a lowmelting point metal lump 32 being surrounded around four sides of the fuse element 26. Consequently, even if the fuse 21 is mounted in any setting position of upward, transverse, and downward positions, the low-melting point metal lump 32 is scattered to the same degree in a fusion part 25a positioned in gravitational direction, and an alloy layer is formed. Even if the fuse 26 is mounted in any setting position, since a scale of joule's heat generated at the alloy metal of the same degree is identical, distortion in fusion time is never generated, and normally stable fuse characteristics are made possible.

Title: Processor and instruction take-out method for selecting one of plural take-out addresses generated in parallel to generate memory request
Inventor: DHONG SANG H
IPC: G06F9/32
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To shorten an instruction take-out wait time by generating a target address and sequential addresses and the a select signal in parallel. SOLUTION: A decoder 40 determines the target address according to an instruction in a take-out window 38. Further, an adder 48 calculates sequential take-out addresses from the address of the final instruction in an instruction queue 30 and the length of the final instruction. Then priority order logic 42 decides whether or not an unprocessed branch instruction is included in the take-out window 38. When it is decided that no unprocessed branch instruction is included, the priority order logic 41 selects the sequential take-out addresses. A multiplexer 50 selects at least one of decoded input addresses as a memory request address in response to the select signal 52. Then when the solution that the target address is correct is obtained, instructions in a sequential path can be discarded.

Title: Semiconductor package
Inventor: YAMASHITA HIROBUMI
IPC: H01L23/06
Filed: 1989-03-29
Abstract: PURPOSE:To realize light weighty to make heat-dissipating effect large and to effectively prevent a semiconductor element from being cracked or chipped off by a method wherein a package main body is formed of a specific aluminum- silicon alloy. CONSTITUTION:A package main body 1 which houses an integrated circuit for microwave band use or the like of a semiconductor package is formed of an alloy which is composed of 50 to 80wt.% of aluminum and 50 to 20wt.% of silicon. When a ratio of aluminum to silicon is changed for this alloy, it is possible to adjust its density, thermal conductivity and coefficient of thermal expansion. Since the package main body is strongly resistant to a thermal stress which is caused by a rapid heating operation and a rapid cooling operation during a welding operation, a solidification crack or the like is not caused even when the package main body is laser-welded. Thereby, a thermal stress caused by a difference in a coefficient of thermal expansion between the package main body and a semiconductor element is eliminated; long-term reliability is enhanced by preventing the semiconductor element from being cracked, chipped off or the like.

Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a stable discharge and to reduce the dispersion of pulse energies by making the contents of oxygen of discharging electrodes a specific ratio or less. SOLUTION: The ratio of the oxygen content of each discharging electrode A16, A17 is made 10ppm or less. It is desirable that the ratio should be 1ppm or less.

On the other hand, if discharge is performed the electrodes A16, A17 deteriorate and are consumed in shape, and the shape of the electrodes A16, A17 changes. When an inactive gas is led in, and discharge is performed for several seconds, the tips of the electrodes A16, A17 melt, and the electrodes A16, A17 are shaped. A laser chamber AO1 contains a heat exchanger A21, a blower A20, the electrodes A16, A17, and so on. For the electrodes A16, A17, a Heins alloy whose oxygen concentration is 9ppm for example is used.  And, F2 , Kr, Ne gases are put in the laser chamber AO1 and it is sealed.
