Title: Folding ruled line of corrugated fiberboard case material and case manufacturing machine
Inventor: YAMAMOTO MANKICHI
IPC: B31B50/25
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent positioned deviation and bent of a folding crease in bending a corrugated fiberboard case material along a ruled line in a crease direction of the material. SOLUTION: Adjacent parts 11b, 11b', 12b, 12b' obtained by intermittently collapsing advance to main ruled lines 11a, 12a extended in a crease direction of a corrugated fingerboard case material 10 are formed. The adjacent parts are formed laterally asymmetrically at part or entirely of overall length of the main ruled line part, and for example, formed only at opposite side to a direction that the folding line is easily deviated at the time of folding. When the ruled line is to be folded, since mean strength of a corrugating material of the fiberboard is lowered at the adjacent part, one of the main ruled line is more easily collapsed, thereby preventing positional deviation or bending of the folding line in a specific direction at the time of folding.

Title: Power supply circuit
Inventor: AZEGAMI TADASHI
IPC: G05F1/565
Filed: 1984-08-17
Abstract: PURPOSE:To secure the stable internal voltage regardless of a current consumption amount by combining a current route formed by a series circuit of a constant current control means and a detecting resistance and a current consumption means which compensates the change of current consumption of an internal circuit. CONSTITUTION:An end of a constant current element Q1 is connected to an input terminal T1 of a power supply circuit, and a detecting resistance R1 and a constant voltage element DZ are connected in series between a common terminal T3 and the other end of the element Q1. A bridge of resistances R2-R5 is connected to the gate of the element Q1 via an operational amplifier Q2; while a resistance R11 is connected from a bridge of resistances R6-R10 via an operational amplifier Q3. Thus a receiving current I1 is constant as long as the voltage EZ of the element DZ is kept constant. Then both currents I3 and I4 are also fixed. In addition, the internal voltage Ei is constant regardless of the value of the current I3 as long as the current I1 and a current (I3+I4) are kept constant. Then a circuit to be energized can consume the current within a range of (I3+ I4).

Title: Manufacture of semiconductor device
Inventor: SASAKI NOBUO
IPC: H01L21/26
Filed: 1982-09-30
Abstract: PURPOSE:To maintain the electric characteristics of a semiconductor element by a method wherein, in the case of laser irradiation where a shifting of flatband voltage is generated in the laser process, a low power laser beam is reirradiated, thereby enabling to recover the flatband voltage to the level maintained before shifting. CONSTITUTION:When a powerful laser beam is irradiated on a silicon substrate 1 whereon an oxide film 2 is attached, silicon is fused and the stress of the oxide film 2 is released, and an unevenness phenomenon is generated. When a laser beam having the power of 7-8W is irradiated on the uneven part, the flatband voltage is restored. Accordingly, when the laser, having the power with which a change is made in flatband voltage due to having the laser process such as activation and the like of the ion layer of the substrate, is irradiated, a laser beam of low power of 7-8W is reirradiated after the irradiation of laser. Said low power laser irradiation can be performed easily by lowering the power of the source of laser beam. Also, the period of irradiation of such a low power laser irradiation is determined by measuring the time required for recovery of the flatband voltage in advance. Accordingly, the above-mentioned laser irradiation can be performed easily using the laser irradiation device used before.

Title: White balance adjustment method and computer-readable recording medium
Inventor: ITO KENICHI
IPC: H04N9/73
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To adjust white balance simply and with high accuracy in a short time. SOLUTION: In a step ST71, whether an adjustment end value is stored is discriminated. When adjustment of the white balance of an image display device is finished already and the image display device stores the adjustment end value, the adjustment end value stored in a step ST72 is used to decide the adjustment initial value of an image display device whose white balance is next to be adjusted. The operation of the image display device is set by using the above adjustment initial value and the image display device displays an image for adjusting the white balance. The color of the adjustment image is measured and an adjustment value by which the measurement result is brought into a predetermined adjustment standard range is obtained in steps ST73-75. In a step ST76, this adjustment value is stored as an adjustment end value.  The processing in the steps ST73-75 can be finished in a short time by using the stored adjustment end value to decide a succeeding adjustment initial value.
