Title: Flux for coating
Inventor: SEIKE NORIO
IPC: B23K35/365
Filed: 1984-07-04
Abstract: PURPOSE:To improve the binding strength and dislodging-resistant performance of a flux by incorporating specific weight % of alkali metal ions and Cl ions into the flux and adjusting the ion compounding ratio expressed by the ion concn. ratio within a prescribed range. CONSTITUTION:The Cl ions are incorporated at 0.0005-0.011% in the form of the Cl-contg. water glass added with Cl ions to water glass into the flux and further the alkali ions are incorporated at 0.5-2% therein by compounding of an alkali metal compd., etc. The ion compounding ratio expressed by the ratio between the concn. of the alkali metal ions and the Cl ions is adjusted within a 100-3,000 range. The binding strength of the flux is improved by the oxidation effect of the Cl ions for the surface of a wire. The moisture absorption of the flux is prevented by the alkali metal ions incorporated therein. The rate of oxidation reaction is adjusted by the balance of the ion concn. and therefore the dislodging resistance is improved.

Filed: 1978-11-13
Abstract: PURPOSE: To make it possible that the memory unit side has a TEST&SET instruction by setting a read operation state and a write operation state in the first half and the latter of one operation cycle respectively in respect to memory access.  
     CONSTITUTION: AND between memory access signal 10 and the result obtained by decoding 6 the signal on address bus 9 is operated in 8C, and memory unit 4 is accessed. Read of read/write command R/W to memory 4 is performed in a low level, and a write command is delayed by a fixed time by delay line 7a and is given to memory 4 through AND gate 8a. Consequently, the read/write command can be defined as a read command in the first half of memory access and can be changed to a write command in the latter at the end of read. In respect to write data, all "1" or "0" data is written in the memory according to presence or absence of signals on command line 11 sent from a processing unit. Read data from memory 4 is transmitted to data bus 12. The response signal for memory access is transmitted to response signal line 13 after delayed by a fixed time in 7b, so that the TEST& SET function can be realized by memory control circuit 5.

Abstract: PURPOSE:To obtain a flat characteristic over the entire frequency by providing a metallic damper supporting a magnetic circuit and a magnetic fluid filled in a magnetic gap in a magnetic circuit so as to suppress the peak of the primary resonance level at a low frequency. CONSTITUTION:The magnetic circuit 10 is contained in a casing 18, the peripheral ridge of the circuit 10 and the casing 18 are connected by the metallic damper 19 and the circuit 10 is supported in a suspended way in a space at the inside of the casing 18.

IPC: H02P1/42
Filed: 1980-10-06
Abstract: PURPOSE:To prevent the flowing of abnormal currents through auxiliary winding by mounting a protective device responding to the currents of the auxiliary winding. CONSTITUTION:When a control switch 11 is closed and a power supply is made, the auxiliary winding 3 is conducted through a capacitor 5 for starting because a bimetal contact piece 7 contacts with the fixed contact a side. When the bimetal contact piece 7 generates heat and is deformed to a condition that contacts with the fixed contact 6 side, the auxiliary winding 3 is conducted through a capacitor 6 for operation. When overcurrents which cannot be detected by means of an overload protective relay 13 flow through the auxiliary winding 3 during operation, an overcurrent protective relay 15 is actuated, and condution to the auxiliary winding 3 is interrupted. Accordingly, the flowing of abnormal currents through the auxiliary winding can be prevented.

Title: Stainless steel sheet with high brightness, excellent in ridging resistance and workability, and its production
Inventor: YOKOTA TAKESHI
IPC: B21B3/02
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a stainless steel with high brightness, satisfactorily excellent in ridging resistance and press workability, by providing a specific range of crystal-orientation distribution in the arbitrary plane perpendicular to rolling direction and parallel to plate-surface normal. SOLUTION: The ridging resistance of the steel can be greatly improved by regulating the value of d hkl}/t to <=0.3, where d hkl} is the length (μm) of an  hkl} colony in sheet-thickness direction and (t) is sheet thickness (μm) and the  hkl} colony is a group of crystalline grains in which the orientation vector in the direction perpendicular to the plane surface of respective adjacent crystals is within 15 deg from the <hkl> direction, that is, the ridging height can be greatly improved by regulating the colony size in sheet-thickness direction to <=30 vol.% of sheet thickness. This is because ridging is generated as the sum of the amounts of plastic deformation of respective crystals.  Further, workability can be improved because deformation in sheet-thickness direction is made uniform, and the degree of brightness can also be improved because of the decrease of oil pits at the time of rolling deformation and the uniform deformation of the surface of the steel sheet.
