Title: Build-up welding method of inside surface of pipe
Inventor: HATSUTORI MASAJI
IPC: B23K9/12
Filed: 1984-04-02
Abstract: PURPOSE:To perform defectless and stable build-up welding of the inside surface of a pipe by detecting the coincidence of the height displacement of a welding torch provided to the top end of an arm with a reference value, upsetting the torch and profiling the end face of a bead thereby obtaining the smooth beads. CONSTITUTION:The oscillating direction of the welding torch 2 attached to the top end of the arm 7 consisting of a slender pipe is checked in continuous build- up welding of the inside surface of a pipe in which an arc voltage is controlled. The height displacement eA of the torch 2 is detected if the oscillating direction is in the direction of the build-up bead 5. The upsetting signal for the torch 2 is detected where the displacement eA rises up to set reference potential er. A command for stopping oscillation is emitted after time TA(sec) and the torch 2 is upset upon lapse of stop time TB. A set oscillating width W is detected and the torch 2 is upset if the oscillating direction of the torch 2 is on the side where there is no bead 5. The generation of an undercut or the trough in the lap part of the bead is eliminated by the above-mentioned method.

Title: Method and device for transmitting pulse signal and semiconductor switch suitable for transmission of the same
Inventor: KAWABATA SHIGEYUKI
IPC: H03K5/003
Filed: 1989-03-17
Abstract: PURPOSE:To transmit a pulse signal in two directions by using a unidirectional semiconductor switch without increasing the size of the switch by superimposing an offset current on the pulse signal so as to make a positive pulse larger than a negative pulse. CONSTITUTION:When the pulse signal consisting of the combination of the positive pulse with a forward direction to the semiconductor switch 4 and the negative pulse with a backward direction is transmitted by using the semiconductor switch 4 which shows conductivity modulation at an on-state, the offset current Ios is superimposed on the pulse signal so as to make the positive pulse larger than the negative pulse. Therefore, the offset current Ios makes a peak value at a positive pulse side larger than that at a negative pulse side when passing the semiconductor switch 4, thereby, which makes a reverse recovery period and a reverse recovery current larger than pulse width and the peak value. In such a way, it is possible to transmit the pulse signal in two directions by the unidirectional semiconductor switch without generating waveform distortion.

Abstract: PURPOSE:To obtain the MOSRAM device resistive to alpha rays by a method wherein the high density buried layer, having the homopolarity with a substrate, is provided at least on the lower part on either of a capacity section and a reverse conductive type diffusing region. CONSTITUTION:A P<+> layer 8 is implanted at the location where the cell capacity will be formed for a P type Si substrate 6, for example, and a P type epitaxial layer 7 is deposited on the whole surface. On this epitaxial layer 7, an FET is formed on a memory cell by providing the diffusion layer 5 to be used as a capacity electrode 2, a gate electrode 3 and a bit by means of a double-layer polycrystalline Si technique.
