Title: Solder material and method for joining
Inventor: ABE SHUNICHI
IPC: H01L21/52
Filed: 1992-07-16
Abstract: PURPOSE:To eliminate variance in treating time for a high melting point and to shorten the time by forming a solder layer thinly on one material to be joined and forming a higher melting point solder layer more heavily on the other material to be joined. CONSTITUTION:A solder material is constituted of a thin first solder layer (Sn layer 5) which is formed by a vapor deposition or a sputter method on one material to be joined (semiconductor element 1) and a second solder layer (Pb layer 6) which is formed on the other material to be joined (die pad 2) and is provided with a higher melting point and a heavier thickness than the first solder layer. Then, both materials to be joined are superposed and heated to the temperature not more than the melting point of the first and the second solder layer to form an eutectic solder layer 7a; this two layered solder layer is heated to make a high melting point and both materials to be joined are soldered together. Thus, the treating time for a high melting point is extremely shortened.

Title: Electronic controller
Inventor: KOMORI HIROKAZU
IPC: G05B11/36
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To set keeping/stopping of power supply at the time of rewriting a program according to the importance of the program stored in a flash ROM. SOLUTION: A boot program or a control program and data for internal combustion engine stored in a flash ROM 13 are rewritten by a flash ROM rewriting processing by the microcomputer 11 of an ECU(electronic controller for internal combustion engine) 10. At this time, since the boot program becomes non-rewritable when power supply is disconnected during the rewriting of the boot program, a main relay control circuit 19 is controlled to keep power supply from a main relay 22. In the case of the other programs, etc., since interruption in the middle of rewriting is possible, the whole power supply is disconnected by an ignition switch 21. Thus, it is possible to set keeping/stopping of power supply at the time of rewriting the program according to the importance of the program stored in the flash ROM 13.

Filed: 1989-07-21
Abstract: PURPOSE:To detect a paper sheet set tilt with high accuracy by providing a tilt discrimination means correcting a dispersion between a step number detected by a carrier motor when each paper sensor detects and operates and a step number stored in a dispersion storage means through the comparison and discriminating a carried picture read paper set tilt.

Title: Frame synchronizing device
Inventor: ARAKAWA TADAHIRO
IPC: H04J3/06
Filed: 1984-09-11
Abstract: PURPOSE:To automatically correct an erroneous output of a frame synchronizing signal which is outputted by means of a false synchronizing signal, by providing a synchronization hold inspecting circuit and always inspecting the rightness of frame synchronizing signals. CONSTITUTION:A synchronizing bit pattern detecting circuit 4 takes the bit correlation between a digital input signal and synchronizing bit pattern and sends a subframe synchronizing signal (b) to a synchronism securing circuit 5 and synchronization hold inspecting circuit 9. The circuit 5 takes the correlation between frames from the signal (b) and outputs a main frame synchronizing signal (f). An 1-frame counter circuit 6 outputs an inspecting signal (d) of one frame to the circuit 5 and, under the self-running mode, a frame synchronizing signal (c) instead of the signal (f). The circuit 9 starts synchronism inspecting operations immediately after the synchronism is secured and, when the signal (f) rises, resets the circuit 6 by outputting a signal (g) and resets the initial value of the counter. At the same time, the circuit 9 commands the circuit 5 to secure the synchronism again. The circuit 5 stops the operation of the circuit 9 by outputting an operation inhibiting signal (e) to the circuit 9 and, at the same time, causes a selection switch 10 to select the signal (c).

Abstract: PROBLEM TO BE SOLVED: To prevent turning together and contrive uniform soil improvement of high quality by providing a first agitating unit and a second agitating unit in parallel, driving each drive sprocket by a separate hydraulic motor and driving each agitating chain with fins in mutually reverse directions. SOLUTION: Respective rotation directions and rotation speeds of hydraulic motors 8, 9 can be separately arbitrarily varied. Chains with fins 20, 21 are driven in reverse directions to deliver and move clod between both units A, B. Furthermore, agitating fins 22, 23 withdraw a solidifying agent scattered on a ground surface into a ground, and agitating and mixing are performed so as to transmit it to the other unit side. In this case, since scattering is prevented during and after spraying of the solidifying agent such as a cement powder by strong wind, the whole device 3 is covered by a bellows expansion and contraction skirt bringing a lower edge opening end into contact with a ground surface.  Thus, the agitating and mixing device 3 can be shallowly or deeply inserted into soil, delivery and movement of clod are performed between a plurality of units to be fined and uniform mixing by agitation of the solidifying agent can be performed.
