Abstract: PURPOSE:To adapt for a high speed operation and highly integrate a semiconductor memory device by using a lateral P-N-P type transistor as a load element of a memory cell. CONSTITUTION:In a bistable circuit type semiconductor memory device, an N-P-N type transistor is composed of an N type region 4 as a collector region, a P type region 5 as a base region and an N type region 7 as an emitter region, and a lateral Schottky barrier collector transistor is composed of a PtSi region 9 as a collector region, an N type region 3 as a base region and a P type region 8 as an emitter region. This transistor is formed by substituting the base and collector junction of a lateral P-N-P type transistor for an SBD.

Title: Bending method of a plurality of rod shape insulated conductors and apparatus for the same
Inventor: HORUSUTO ENGERUMAN
IPC: H02K15/04
Filed: 1986-10-09
Abstract: For manufacturing approximately hexagonal coils for the rotors of electrical machines, conductor assemblies must be bent into the desired shape. In this case, curvature in the spatial direction is also required as well as the special contour. Until now, such conductor assemblies have been bent either purely manually, by matching them to a template, or also mechanically, by means of separate work processes in which the contour of the conductor strands was produced first followed by the spatial curvature. According to the invention, the individual bending processes are carried out about different spatial axes within the course of a single handling of the conductor assembly. In the associated device, with a U-shaped end of a rod clamped in a retaining device, stop parts (110, 120, 130, 140, 150, 160) are provided as a boundary of the templates for the conductor strands (10; 11 to 16), to which stop parts there is allocated in each case one bending head (210, 220, 230) with moving bending fingers (215, 225). <IMAGE>

IPC: H01L21/265
Filed: 1986-10-09
Abstract: PURPOSE:To prevent faults and quality accidents in a device by sensing malfunctioning of an ion beam interrupting part and forming an interlocking circuit in which ion beams are forcedly interrupted. CONSTITUTION:Ions generated in a device are drawn out by an ion beam drawing power source 1 and implanted in semiconductor substrates 3 disposed on a rotating disk 2. When interruption of the ion beams 4 are required for replacement of the substrate 3 or so, structure of a beam interrupting part 5 allows the beams traveling to be interrupted.

If a beam interrupting part 5 becomes into its non-closed state when the disk 2 is not rotated, the ion beam drawing power source 1 is turned forcedly OFF and so the ion beams 4 are interrupted. Thus, faults and quality accidents in the device can be prevented.
