Title: Treatment of aluminum remaining ash
Inventor: MIYAKE MAKOTO
IPC: B09B3/00
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To surely remove aluminum nitride and to improve the durability of a refractory and a machine device used for combustion by perfectly burning an aluminum remaining ash to oxidize metallic components. SOLUTION: The powdery aluminum remaining ashes 2 having about 8μm grain diameter, are almost uniformly dispersed to the granular aluminum remaining ashes 1 having >=10μm grain diameter produced in an aluminum melting process over the whole body and heated at about 500-900 deg.C without unevenness over the whole body. By this method, the dispersed powdery aluminum remaining ashes 2 are ignited one by one and flux component 5 contained in the powdery aluminum remaining ash 2 becomes in fused condition and invades into gaps among the granular aluminum remaining ashes 1 and the granular aluminum remaining ashes 1 are slowly burnt over the whole body by heat insulating action of this flux component.

Title: History collection system
Inventor: INOUE HIROYUMI
IPC: G06F11/34
Filed: 1990-04-26
Abstract: PURPOSE:To easily and quickly restore a broken block without using any saving file by outputting the entire history information on the block even though the block is partly updated in a data file when the updating information is outputted to a history file. CONSTITUTION:A history output means 102 outputs the entire unupdated contents of a block 202 to be updated by an updating means 101 and the contents of the updated part to a history file 104 as the history information. Then the means 101 sends the entire updated contents of the block 202 to an external storage 201 in order to update a data file 103. Therefore the entire contents of the broken block 202 can be restored when the unupdated contents of the block 202 outputted to the file 104 are written again into the broken block 202. As a result, a broken block can be easily and quickly restored without using any saving file.

Filed: 1990-04-26
Abstract: PURPOSE:To allow molten metal to fly after being made into dust from nuggets of materials to be welded by bringing the pressurizing direction of an electrode chip for pressurization in line with the deflecting direction of an electrode chip for receiving which has received pressurizing force. CONSTITUTION:At the time of pressurizing, since the pressurizing direction of the electrode chip 12 for pressurization is almost brought in line with the deflecting direction of the electrode chip 6 for receiving, the tip face of the electrode chip 12 for pressurization and the tip face of the electrode 6 for receiving are maintained in an almost parallel state. In addition, the pressurizing force acted on the tip face of the electrode chip 6 for receiving from the tip face of the electrode chip 12 for pressurization almost points to the axial direction of the electrode chip 6 for receiving. Accordingly, in 4 pressurizing state, when a welding current is carried, it can be prevented that the molten metal flies after being made into dust from the nuggets of a baffle plate B and a muffler pipe M and the nuggets are maintained and the quality of welding can be stabilized.

Abstract: PURPOSE: To make readily possible drawing of the wire material compose of brittle material by applying axial pulling force to the wire material from the feed side of the plural dies disposed in the drawing direction and applying their axial compressive force to the wire material from the respective die inlet side.  
     CONSTITUTION: A wire material 1 is pushed into a die 4 by a pusher 2 and is given compressive force in its axial direction. At the same time, it is subjected to plastic deformation in the die 4 by the pulling force added by a puller 3, whereby sectional reduction is applied. Next, it goes through a capstan 5 and is subjected to sectional reduction by dies 4', 4", etc. in the similar manner as above subsequently as much as required times. In pushing, buckling is prevented by the guiedes 6, 6', 6" between the dies and pushers and the pushers and pullers are held of their dispositions by the grips fixed to a pair of endless chains or belts disposed opposedly in the drawing directions, whereby the pulling forces and compressive forces are applied simultaneously. In this way, the rate of sectional reduction in one pass is increased and the fabrication of the wire material of brittle material becomes easy because the pulling forces are lower.

Abstract: PURPOSE:To make an output DC voltage constant regardless of the gain by connecting a transistor (TR) in parallel with each of two TRs of differential connection and giving a gain variable voltage to a base of TRs connected in parallel. CONSTITUTION:The differential amplifier consists of a constant current source consisting of a TR 30 and resistors 31, 36, 37, a differential amplifier section formed by TRs 26, 29 and resistors 32, 33 acting like load resistors 32, 33. Then collectors of the TRs 27, 28 whose bases are connected are connected to collectors of the TRs 26, 29 respectively and the base of the TRs 27, 28 is biased by DC bias from a variable voltage power supply 29. Through the constitution above, the total sum of collector currents of the TRs 26-29 is always equal to a current IC30 of a TR 30 constituting a constant current source. Let Ie25-Ie29 be emitter currents of the TRs 26-29, the relation of Ie26+Ie27= Ie29+Ie28=IC30 is established independently of the voltage of the power supply 39 and since the IC30 is a constant current and independent of the voltage of the power supply 30, the DC potential of output terminals 34, 25 becomes a constant voltage.

IPC: B41J2/485
Filed: 1992-04-30
Abstract: PURPOSE:To perform an emphasis printing or the like at a high speed or a constant speed without the need for an exclusive ROM or the like by providing a drive control means which outputs drive signals at a fixed period when detecting an effective state of a printing signal to drive each driving part. CONSTITUTION:When a writing signal from a CPU is inputted to a writing terminal T with an input terminal D1 of a latch circuit 30 in an H level or an effective state, printing data is written in the circuit 30. With the falling of the signal T, H-level printing signals are outputted from an output terminal Q1 corresponding to the terminal D1 until the input of a next writing signal. With the output of the printing signal from the terminal Q1, a terminal Qa turns to an H level and a terminal Qb to a L level in a flip flop 35. Thus, a counter 38 starts counting clock signals supplied to a terminal CLK. At this time, a first comparator 40 before the counter 38 reaching a set value outputs an H-level signal, thus outputting a drive signal through an AND gate 36 to make a transistor 15 in an ON state to start an electric conduction for printing to a solenoid 13.

Title: Lead 1-bit detecting circuit
Inventor: ARAI SEIJI
IPC: G06F7/74
Filed: 1990-04-27
Abstract: PURPOSE:To decrease the maximum number of bits to be transmitted for a carry and to detect a lead 1-bit at a high speed by dividing the registers into plural groups and providing a carry line and a carry buffer to each group independently of each other. CONSTITUTION:The registers 10 - 17 are divided into groups 10 - 13 and 14 - 17, and the carry lines 8a and 8b and the carry buffers 12a and 12b are provided to these two groups of registers independently of each other. Thus the maximum number of bits to be transmitted can be decreased for a carry. That is, if a register has 16 bits in all, these bits are divided into four groups every four bits. Thus it is just required for a single carry buffer to drive a carry line having the 4-bit length at maximum. Therefore the carry transmission speed is never deteriorated despite a lead 1-bit included in a lower rank.
