Title: Mold material for continuous casting with built-in electro-magnetic mixer
Inventor: MIYATO MOTOHISA
IPC: C22C9/06
Filed: 1988-01-22
Abstract: PURPOSE:To reduced the electric conductivity to the range where the magnetic field does not diminish, to improve the proof stress at normal temp. and the heat resistance of the title material and to facilitate its atmospheric melting by specifying the compsn. of the title mold material. CONSTITUTION:The mold material contains, by weight, 0.4-4.0% Ni, 0.1-1.0% Si, 0.05-5.0% Zn, 0.1-2.0% Sn, 0.02-1.0% Mn, 0.001-0.01 % Mg and one or more kinds among 0.001-0.01% Cr, Ti and Zr and the balance consisting of Cu. In the material, since Ni and Si form the deposits of Ni and Si contributing to the improvement of the strength, the above range must be independently incorporated thereto; and since Ni regulates its electric conductivity to the required value, <=2.0% is needed, and because of the improvement of its strength, >=0.1% is needed. The molten metal is oxidized to reduce its fluidity at the time of >0.01 % Mg. Cr, Ti and Zr improve the fining of the crystal grains of the ingot and its expansibility at high temp., but in the case of >0.01% additioning thereof, the oxidizability of the molten metal is made severe.

Title: Cleaning apparatus for welding base metal
Inventor: SAMEJIMA OSAMU
IPC: C23F1/08
Filed: 1980-02-04
Abstract: PURPOSE: To remove skillfully and easily rust formed on the surface of base metal with a cleaning apparatus by generating arc between the base metal with a negative voltage applied and an electrode with a positive voltage applied.  
     CONSTITUTION: Arc generating torch 2 provided with electrode 4 in casing 3 is placed opposite to base metal 1, and arc is generated between electrode 4 with a positive voltage applied and metal 1 with a negative voltage applied. As a result, electrons of metal 1 move to electrode 4, so an iron oxide film on the surface of metal 1 is broken through and removed by emitted electrons to clean the surface of metal 1. Electrode 4 is a hollow rod, and it is prevented from being superheated by feeding cooling water to feed water pipe 10 put in the rod and allowing the water to flow out of discharge pipe 11. In the drawing, 13 is a gas supply inlet.

Title: Heat-exchanger
Inventor: HATADA TOSHIO
IPC: F28F1/32
Filed: 1979-02-07
Abstract: PURPOSE:To improve heat transfer performance, increase the strength of fins and make then thin by making slits in the fin perpendicularly to the flowing direction of the liquid, forming the slit pieces in a specified shape and shifting the height position of the neighboring edge part in the specified form. CONSTITUTION:Fluid for heat exchange flowing in the direction of A flows in the direction of the arrow due to the tiny pieces 14a-14c formed on a fin. As a result, a temperature at interfacial layers 20 of an air current can not develop fully between the fore and back ends of a piece 14a and becomes much thinner than usual. Therefore, the heat exchange efficiency between the face of fin and the air current can be improved remarkably. In addition, since many tiny pieces are bent and arranged in the form of stairs, the fall of the strength of fin to be caused by slits can be prevented, or rather the strength can be increased, which, in its turn, makes thinning of the fin possible.

The dust is removed together with the bubbles from the upper part of the aeration tank 3. This water is subjected to temp. control by a refrigerator 5 and is then returned through the biological treatment vessel 6 into the breeding water tank 1.  As a result, the treatment of the harmful ammonia at a low temp. is made possible and, therefore, the damage, etc., of the fish are suppressed.

Title: Instantaneous contact type ultrasonic flaw detecting method
Inventor: MATSUMOTO KIYOSHI
IPC: G01N29/04
Filed: 1979-02-05
Abstract: PURPOSE: To obtain a constant level of ultrasonic wave transmitting to a inspected object by providing an ultrasonic flaw detecting system having a flaw detecting main transducer disposed on the central axis of the flaw detecting and an auxiliary transducer disposed so as not to interfere with the signal from the main transducer.  
     CONSTITUTION: A flaw detecting main transducer 9 having a spherical lower face 8 for contact with an inspected object 7 is disposed on the axis of the flaw detecting head. Auxiliary transducers 10, 11 of the transmitting and receiving sides for the monitoring purpose have resonance frequencies which are different from that of the main transducer 9. These auxiliary transducers 10, 11 are so orientated that the monitoring signal does not interfere with the flaw detecting signal from the main transducer 9. Assuming here that a sine wave curve signal 12 is transmitted, the signal is reflected by the lower face 8 and is then received. The main transducer 9 is excited when a predetermined level of the monitoring signal is reached, so that the level of the ultrasonic wave transmitted through the inspection object 7 can be maintained constant.

Title: Dma controller
Inventor: KIKUCHI MICHIYO
IPC: G06F13/28
Filed: 1995-01-30
Abstract: PURPOSE: To provide a DMA controller which can minimize the influence on the entire processing speed of the DMA transfer when a transfer error is detected. CONSTITUTION: A table access control part 2 takes the DMA operation data out of an operation definition table 1 and stores the data in an internal register 3. A DMA transfer control means 5 controls an I/O bus 8 based on the operation data taken out of the table 1 and carries out the DMA transfer. A transfer abnormality detection means 6 monitors the transfer contents. When a transfer error is detected, the means 6 writes the error contents in an error information table 7 and also outputs a wait signal to a table access control part 2 to retract the take-out of the next operation data. And, the means 6 outputs a retry signal to the means 5 and judges a normal or abnormal transfer result obtained by a retry operation by comparing this result with the contents of the table 7.  If the normal DMA transfer is impossible even when the retry operations are carried out in the set frequency, the means 6 outputs a transfer abnormality signal to a CPU.

Abstract: PROBLEM TO BE SOLVED: To provide a vibration-type gyroscope which can increase the detecting accuracy of an angular velocity by a method wherein a change in the phase of a detection output can be detected with higher accuracy than in conventional cases. SOLUTION: Two detection output parts are installed at a vibrator. In the detection output parts, an output can be output at an in-phase when an angular velocity is not given (a null output F0), and an output can be output at an opposite phase in which a Coriolis output component FωC and a Coriolis output component FωD are opposite to each other. An output C and an output D from both detection output parts become the vector sum of the null output F0 and the Coriolis output component FωC and the vector sum of the null output F0 and the Coriolis output component FωD. When the phase difference ϕ between the detection output C and the detection output D is found, the detecting sensitivity of the Coriolis output components can be increased.

Title: Channel selector
Inventor: TAKESHITA MASAHIRO
IPC: H03J5/00
Filed: 1978-02-07
Abstract: PURPOSE: To ensure an easy channel selection for many channels through a simple constitution by combining two pairs of switch circuits via the gate group and then presetting them at the making time of the power source.  
     CONSTITUTION: With making of the power source, the output of a low level is produced at output terminal (a) of the lowest step in switch circuit 13 through operation of preset circuit 10 and 20. At the same time, the output of a low level is generated at output terminal (p) of the highest step in switch circuit 23. Thus, the channel set by variable resistor 11a is selected. Here, with operation of switch 9U, the output is generated from 1-step higher output terminal (b) and also from 1-step lower output terminal (p) with operation of switch 9D respectively. In this way, switch circuit 13 and 23 are combined by gates 31∼38 and then preset at the powder making time. Then output terminals (a)∼(o) are shifted sequentially in the higher or lower direction to generate the output. Thus, the selection is possible for many channels through a simple constitution.
