Title: Overvoltage self-protection type thyristor
Inventor: SHIMIZU YOSHITERU
IPC: H01L29/861
Filed: 1990-08-31
Abstract: PURPOSE:To control a breakdown voltage characteristic with high accuracy by a method wherein a part where an ion distribution density displays a peak value is formed by using a proton irradiation means and a part where a forward breakdown voltage is dropped is formed. CONSTITUTION:At a thyristor element in which electrodes 6, 7 have been formed, a shielding plate 15 is used so that only a region constituting a pilot thyristor part 8 is irradiated selectively with protons; the protons are irradiated from the cathode side of the element. After this irradiation has been finished, a short-time annealing operation is repeated until a prescribed breakdown voltage is obtained. Thereby, a peak region 12 appears in a prescribed position in an n-base layer 3 as shown on the right side in the figure as a damage distribution; a crystal defect production region 13 can be formed. An interaction between ion particles and semiconductor atoms appears strongly inside the region 13; the interaction becomes more strongly and a crystal defect density in a semiconductor becomes maximum in the region 12. An ion distribution and the damage distribution are set to a peak state in nearly the same position and the lifetime of carriers in the semiconductor becomes minimum at this part.

Filed: 1987-09-10
Abstract: PURPOSE:To prevent the damage and contamination of a terminal electrode by providing a pair of short-circuit electrodes, a power source, a magnetic flux detector, etc. CONSTITUTION:Two probes 3 are made to contact short-circuit electrodes 8 in a pair, respectively. Next, a current is allowed to flow through each line wiring by a power source 6. The current supplied flows in parallel through a plurality of wirings, and a magnetic flux is generated in each wiring by this current. This magnetic flux is subjected to magnetic flux detection 7 to be checked for abnormality thereof, and thereby abnormality of the wiring can be checked up. When any magnetic flux is not generated particularly in the wiring on the occasion, said wiring is ascertained to be disconnected. After one wiring is checked up, the detector 7 is transferred along the direction of a column by a controlling-measuring device, and a magnetic flux generated by a subsequent line wiring is detected. On the occasion, the electrodes 8 and the probes once made to contact with each other at the beginning may be left as they are. Since no contact is made with a terminal electrode 1, the damage and contamination of the electrode 1 can be prevented.

Title: Manufacture of coil-like heating unit
Inventor: TAKEDA YOSHINOBU
IPC: B29C45/73
Filed: 1990-08-30
Abstract: PURPOSE:To prevent fusion at the time of electrification by thinning a part of a heating wire by preventing that excessive tension is applied to the heating wire in the case where a coated pipe is wound spirally round an outer circumference of a cylinder, by a method wherein at the time of insertion of the heating wire into the foregoing coated pipe, after the heating wire is formed into a corrugated form, the same is inserted into the coated pipe. CONSTITUTION:Instead of insertion of a heating wire in a straightlike state into an insulation pipe, a heating wire 10 meandering in a corrugated form is inserted into the insulation pipe. Since the subject method is constituted as above, at the time of winding up of a formed heating part spirally round a cylinder, tensile force to be applied to the heating wire 10 can be absorbed reliably. Therefore, neither the heating wire is thinned by being extended partly nor the thinned part of the heating wire is fused.
