Title: Roller feed mechanism for cable laying equipment
Inventor: HARA MOTOJI
IPC: H02G1/06
Filed: 1991-02-25
Abstract: PURPOSE:To prevent the jumping up and melting loss of cable caused by the tilting of a pressure roller forming a roller feed mechanism together with a feed roller. CONSTITUTION:A circular guide plate 21 having the diameter larger than that of a roller is attached to a feed roller 20 and/or a pressure roller 25 at the same center in one united body respectively. Even though a cable 7 trying to jump upward touches the bottom surface of the circular guide plate 21, an excessive frictional force due to sliding at a high speed will not occur because there is no difference in relative speed between the cable 7 and the plate 21 by which the jumping of the cable can be fully prevented. Therefore, automatic feeding of smooth cable 7 can be assured.

Title: Schottky-barrier-gate field-effect transistor
Inventor: TAKEUCHI MAKOTO
IPC: H01L21/338
Filed: 1979-03-15
Abstract: PURPOSE:To increase gate voltage resistance, by increasing the carrier density in the semiconductor layer gradually from the surface toward the substrate, when a Schottky-barrier-gate FET is formed by providing a semiconductor layer on a semi- insulator substrate. CONSTITUTION:n-type GaAs thin film 2 if grown on semi-insulator substrate 1. Schottky-barrier-gate electrode 3 is formed on its center surface, and on both sides surrounding this and at an interval, source and drain regions 4 and 5 are formed, and thereby a MESFET is constructed. In this structure, the carrier density in layer 2 is not made uniform, but its distribution is made to increase in the direction of increasing thickness: when the thickness of layer 2 is 0.2-0.5mum, the absolute value of the density is 1-8X10<16>atoms/cm<3> in the neighborhood of the surface, and 1X10<17>atoms/cm<3> in the neighborhood of the boundary of substrate 1. In this way, since the density in the neighborhood of the surface is lowered, the electric field here is lowered. consequently, the gate voltage resistance is improved to 15- 20V compared to about 10V in the conventional devices.

Title: Semiconductor integrated circuit device
Inventor: ARAI YUJI
IPC: H01L29/78
Filed: 1985-02-20
Abstract: PURPOSE:To protect an internal circuit positively while surely preventing the generation of a latch-up even against abnormal input voltage by forming one part of a diode for an input protective circuit onto a surface oxide film in a semiconductor substrate. CONSTITUTION:A diode D1 clamping voltage inputted to an internal circuit 10 from an input terminal Pin at voltage Vcc on the substrate 1 side is formed by polycrystalline silicon layers 53, 54 shaped onto a surface oxide film 4 in a substrate 1, not depending upon a diffusion layer in the substrate 1. The diode D1 is connected in the forward direction to the substrate 1 side from the input terminal Pin side, thus clamping a large change to the positive side of input voltage. Accordingly, since the diode D1 connected on the substrate 1 side is shaped separated from the substrate 1, a parasitic thyristor is not formed around at least the diode D1, thus positively preventing a latch-up due to the abnormality of input voltage.
