Title: One-side arc welding method
Inventor: KATOU TAKASHI
IPC: B23K9/23
Filed: 1984-01-11
Abstract: PURPOSE:To prevent the low-temp. crack of arc welding from the surface of a groove and the transverse crack of a penetration bead by spraying a flux contg. a viscous binder at a specific rate or below to a specific thickness on a brass backing strip having specific heat conductivity and pressing the strip to the rear of the groove. CONSTITUTION:Flux contg. a viscous binder consisting of carbide of dextrin, grape sugar, etc. a phenolic resin, etc. at an adequate amt. of <=3% is sprayed to 2-8mm. thickness on a brass backing strip having not so much high heat conductivity of 0.20-0.85cal/cm<2>.S. deg.C(20 deg.C). Such backing strip is pressed to the rear of the groove of the materials to be welded and the materials are subjected to arc welding from the front of the groove. Diffusible hydrogen is suppressed in a harmless range by the limited amt. of the binder by which a low-temp. crack is prevented. The poor fluidity of the flux owing to a small amt. of the binder is covered by the relatively low heat conductivity of the backing strip by which the bead part is uniformly cooled and the transverse crack of the penetration bead is pevented.

Abstract: PROBLEM TO BE SOLVED: To attain reductions in cost and the scale of a device by supplying gas separately to an ion-trap mass spectrographic part and an ion source from a gas supply source, and providing independent pressure control mechanisms in branch gas passages. SOLUTION: A gas with low reactivity is supplied from a gas supply source 3-13 to an ion source 3-3 and an ion-trap mass spectrographic part through pipelines 3-15, 3-16 that branch from a connector 3-14. The pipelines 3-15, 3-16 are provided with pressure reducing valves 3-17, 3-18 for controlling the gas inside the pipelines and with pressure gauges 3-19, 3-20, so that the pressure of the gas going toward the ion source 3-3 and that of the gas going toward the ion-trap mass spectrometric part can be controlled independently. Thus a gas pressure, such that a flow rate most suited for ionization is available, can be set at the ion source. At the ion-trap mass spectrographic part, a gas pressure can be set such that degrees of vacuum optimum for confining ions therein are attainable.

IPC: H01L27/146
Filed: 1983-01-14
Abstract: PURPOSE:To inhibit a smear completely by forming an active region of a charge transfer element to a section upper than a light-receiving element. CONSTITUTION:Other regions except a charge transfer region 4 are removed through etching in a semiconductor substrate 1. A reverse conduction type impurity layer 2 is formed on the substrate 1, and a photoelectric conversion element 3, the charge transfer element 4 and a transfer gate element 5, which interposes between the element 3 and the element 4 and controls charges, are set up in the layer 2. When the substrate 1 is brought to an N type and the layer 2 to a P type and reverse bias is applied between these impurity layers, a minimum potential line Vmu is generated in the layer 2. The potential line Vmu is formed to a section nearer to the surface of a semiconductor under the element 4. Consequently, even when a large amount of charges generated under the element 3 are diffused in the lateral direction, a section under the element 4 has potential higher than a section under the element 3, and the potential of the section under the element 4 is close to substrate potential. Accordingly, charges flow to the substrate 1 side, and a smear is not generated.
