Filed: 1992-10-19
Abstract: PURPOSE:To obtain a testing method which eliminates the problem that interruptions by channel ends are reversed by repeatedly re-setting the interruption mask number of a channel device to the interruption mask number of another channel device after the lapse of a certain time. CONSTITUTION:An interruption mask number Z for a channel device 2 on each central processor 1 is fixedly set and an input/output interruption is tested; and the interruption mask number of the channel device 2 is repeatedly re-set-to the interruption number Z of another channel device 2 at every lapse of specific intervals of time, e.g. 60 minutes to test input/output interruptions from all channel devices 2. Therefore, all the channels can be tested when viewed from a specific CPU. The channel number Z set in the specific CPU is fixed for the specific time, so the interruptions of a channel end CE and a device end DE are never reversed even in case of a divisional interruption test.

Title: Steel sheet for enameling excellent in enameling adhesiveness
Inventor: INOUE TADASHI
IPC: C23D3/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To execute enameling of a steel plate eliminating a pickling process without controlling the surface roughness by adhering a film of iron phosphate in a specific quantity on the surface of the steel sheet. SOLUTION: An adhesion amt. of a film of iron phosphate on the surface of a steel sheet is 5-100 mg/m<2> . When the adhesion amt. is below a lower limit value, since an adhesion of P is small, no excellent enameling adhesiveness can be obtained. When the adhesion amt. exceeds an upper limit value, P covers the whole surface, in a case of directly enameling once, Ni is adhered thereto in a plate shape at the time of Ni-dipping and a boundary between the steel sheet and an enameled layer is not roughened at the time of subsequent baking. Further, the boundary between the steel sheet and the enameled layer is not roughened at the time of baking a ground coat in the case of enameling twice. Thus, in neither case, the excellent enameling adhesivity can not be obtained. Any steel substrate can be basically used irrespective of the kind of steel.  By executing the Ni-dipping treatment after the adhesion treatment of iron phosphate, the enameled steel sheet can be used as a pre-treatment eliminated type steel sheet at an enameling manufacturer.

Abstract: PURPOSE:To simply and accurately detect the slippage quantity of a laser beam from the scanned face by providing a pair of knife-edges arranged in the scanning direction of the laser beam, a light receiving element put behind the knife-edge, a differentiating circuit, a peak holding circuit and a computing circuit. CONSTITUTION:A pair of knife-edges 7a, 7b are severally arranged at positions which are mutually opposite in the scanning direction of a laser beam and different in a distance from a scanned face 9, and a light receiving element 1 is provided behind them. An electrical signal issued from the element 1 passes through an amplifier 2 and a differentiating circuit 3, and is divided into peak voltages severally having a signal waveform formed by the two knife-edges. In the case where beam diameters at the two knife-edges are equal, the peak voltages turn into the same output waveforms having mutually different polarities. In the case where a converging point slips from the middle between the two knife-edges, the peak of the waveform formed by the approaching knife-edge rises and therefore narrows in its width, and the peak of the waveform formed by the receding knife-edge lowers and therefore widen in its width. The peak voltage of the waveform formed by the two knife-edges is held by peak holding circuits 5a, 5b, and its absolute value is comparatively computed to give the slippage quantity of the condensing point and its direction.
