Title: Welding wire contained in pail pack
Inventor: FUKUDA EIICHI
IPC: B65H55/04
Filed: 1986-01-07
Abstract: PURPOSE:To feed smoothly a wire to a weld zone by setting an open angle of a bent part of a taking-out terminal wire of a welding wire, to above a prescribed angle which is determined by a yield stress of the wire, and a diameter of the wire. CONSTITUTION:A wire W which has been held upward from the lower face of a wire laminated body 2 in a pail pack 1, and has been stretched out of an inner hole 4 of a holding member 3 is fed to a weld zone through a feed chip 5, etc. In this case, bent parts A (B) are spread out to the right and left, and moved. In said part, the feed chip part is the narrowest, therefore, in this part, a deformation resistance against an expansion of the bent parts A (B) becomes maximum. In order to reduce a feed resistance of the wire by this resistance, open angles theta (thetaa, thetab) of the bent parts A (B) are enlarged as shown by an equation. In this regard, (y) and (d) denote a yield stress (kgf), and a wire diameter (mm), respectively. In this way, an adverse influence exerted on a feeding property of the bent part, of a taking-out terminal wire E can be solved.

Title: Apparatus for forming image
Inventor: YOSHIDA FUTOSHI
IPC: B41J2/45
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To form high-quality images with good processing efficiency without deteriorating finish quality even at the occurrence of errors in the movement amount of a sub scan. SOLUTION: A dot 452 is formed by a main scan and exposure of the (n)th time at an overlapping area 450 formed by a sub scan of a predetermined amount, thereby partly forming a main scan line of the overlapping area 450. A dot 454 is formed at a part without the dot 452 by the main scan and exposure of the (n+1)th time. The main scan line is completed in this manner. Since a boundary part between the dots 452 and 454 is not even in a sub scan direction P, a streak-shaped irregularity extending in a main scan direction W is not given rise to even at the occurrence of an error in the movement amount of the sub scan.

Title: Magnetic sensor
Inventor: TANAKA AKIRA
IPC: G01R33/09
Filed: 1990-01-08
Abstract: PURPOSE:To obtain the magnetic sensor which substantially prevents the generation of temp. characteristic defects and offset defects and can shorten the process for production by forming a wiring part of the extension part of a detecting part and an Al alloy film laminated thereon. CONSTITUTION:The wiring part 3 of the magnetic sensor constituted by forming the detecting part 2 consisting of the thin film of a magnetic material on a glass substrate 1, connecting this detecting part 2 by the wiring part 3 to a terminal 4 for connecting an external electric circuit and covering the front surfaces thereof with a protective film is formed by laminating the alloy film 3b on the part 3a provided by extending the thin film of the ferromagnetic material. The terminal 4 is made contact with the film 3b. The thin film of the ferromagnetic material and the alloy film 3b have a good adhesive property. The current from the detecting part 2 flows only in the alloy film 3b on account of varying resistance values in the part where both are superposed. The thin film of the ferromagnetic material as the wiring part is merely necessitated to be formed by extending the detecting part at the time of forming this part and, therefore, the defective rate at the connecting point is lowered and the process for production is shortened, which eventually lead to a cost reduction.

Title: Method for analyzing minute amount of lead in stainless steel according to emission spectrochemical analysis
Inventor: OISHI TAKASHI
IPC: G01N33/20
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To analyze a minute amount of lead in a stainless steel, by using a wavelength of magnesium as an internal standard element in an emission spectrochemical analysis through spark discharge of lead in an iron steel material by an electric spark discharge. SOLUTION: A wavelength of a primary component element is not used as an internal standard element, but a wavelength (386.8nm) of magnesium is analyzed as the internal standard element. Samples of representative four types of steel in stainless steel are repeatedly analyzed. An average value of analyzed values agrees well with a chemical analysis value, thereby enabling a correct analysis to the chemical analysis value. The analysis method enables a quick analysis of lead in a stainless steel and therefore is applicable to an analysis before melting at a steel melt process an useful to improve quality characteristics of materials. The analyzing apparatus can be operated without skill, so that workability is improved.

IPC: F01D9/02
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To avoid resonance of excitation force and a natural frequency of a moving blade, and to prevent damage of the moving blade by the resonance by setting circumferential directional arrangement of stationary blades to an unequal pitch in the stationary blades to control an air flow flowing in the moving blade arranged on the stationary blade backwash side of a compressor. SOLUTION: In a compressor stationary blade 13 to control an air flow flowing in a moving blade, circumferential directional arrangement of an inserting hole 12 arranged by penetrating through an outside casing 11, is set so as to become different between the stationary blade number of the upper half part of the outside casing 11 and the stationary blade number of the lower half part. That is, a stationary blade 2 arranged in the upper half part of an air passage 7 is set to an upper half pitch angle (θ2 =9.43 deg.), and a stationary blade 2 arranged in the lower half part is set to a lower half pitch angle (θ1 =8.57 deg.).  Thus, in the stationary blades 2 respectively arranged in the upper half part and the lower half part of the air passage 7, an interval between adjacent stationary blades 2 is set to a mutually different dimension to avoid generation of resonance of excitation force and a natural frequency of the moving blade.

Abstract: PURPOSE:To perform the reproduction of signals despite of a head clogging phenomenon and to improve the reliability of a digital signal recording system, by switching successively plural recording means to carry out a recording job in a recording area. CONSTITUTION:The converted digital signals are supplied through terminals 101 and 102, and a multiplexer 11 gives the time division processing to the data on two channels and sends them to a data bus 12.

In this case, such operations are repeated as the read-out operation from the RAM13, the generation of an error correction code by the generator 14 and the rewriting cycle to the RAM13. Thus the data are supplied to a modulator 15 via the bus 12 and modulated. Then the modulation outputs of two systems are supplied to a selector 16, and the selected recording signals drive heads 181-184 via a recording amplifier 17 for execution of a recording job.
