Abstract: PURPOSE:To simultaneously test existence of a defect of a memory region and short circuit between bit lines by simultaneously performing writing data in a first memory region, reading out data to a second memory region, and reading out data from a third memory region. CONSTITUTION:Addresses of memory cells 30, 40, 50, and 60 are made '00', '01', '10' and '11', and initialization data logic '0' is written.

Title: Plasma cutting method with oxygen curtain
Inventor: MATSUYAMA KINICHI
IPC: B23K10/00
Filed: 1983-06-10
Abstract: PURPOSE:To cut a plate body while suppressing intrusion of nitrogen in air into an arc part without rounding the angle at the top edge of a cut surface by using a plasma arc covered with an oxygen curtain around working gaseous oxygen. CONSTITUTION:Working gaseous O2 is blown from the top end of a small diameter nozzle 5a and an arc 8 is generated between an electrode 6 and a plate body 7; at the same time O2 is also ejected to cover the circumference of the arc 8 from the top end of a large-diameter nozzle 5b thereby forming an oxygen curtain S around the arc 8. Such double nozzles 5 are moved toward an arrow A and the plate metal 7 is melted and cut by the arc 8. Since the circumference of the arc 8 is covered by the curtain S ejected from the nozzle 5b, the purity of the working gaseous O2 for the arc 8 is maintained always at a high value and the energy of the arc 8 is substantially high. The top edge of the cut surface is thus formed neatly to a square shape and a bevel angle is made small, by which the finish of the cut part is improved. The cutting of the thin sheet material, etc. having no dross stuck thereto is also made possible.

Abstract: PURPOSE:To make it possible to measure the dispersion and distribution of a wavelength without destruction by measuring the dispersion and the distribution of the wavelength based on the backward scattered light of optical pulses which are guided through an optical fiber. CONSTITUTION:Optical pulses LP1 and LP2 which are the rectangular optical pulse having the wavelength of 1.55mum and the saw-tooth optical pulse having the wavelength of 1.48mum, respectively, are generated with laser-driving-waveform generating circuits 2-1 and 2-2 and semiconductor lasers 3-1 and 3-2 at a repeating period which is outputted from a synchronized signal generator 1. The two optical pulses LP1 and LP2 are synthesized in a wave synthesizer 4. The pulses are introduced into a fiber 6 to be measured through an optical switch 5-1. Immediately after the introduction, the switch 5-1 is switched. The backward scattered light of he pulses LP1 and LP2 is taken out of the fiber 6. Only the light of 1.55mum is taken out through an optical switch 5-2 and an optical fiber 7. The light is transduced into an electric signal in a photodetector 8. The backward scattered optical pulses of 1.55mum is added in an average-response processing part 9. Then the waveform is measured. In an operating part 10, the difference between said waveform and a converted distribution waveform of the wavelengths 1.55mum and 1.48mum which are stored in a distribution value memory part 11 is obtained, and the dispersed and distributed waveforms are outputted.
