Title: Oil-filled submarine cable laying method
Inventor: KOIZUMI YOSHINOBU
IPC: H02G1/10
Filed: 1989-01-09
Abstract: PURPOSE:To limit the range of cable which will not be usable upon occurrence of fault by providing steps in the cable with predetermined interval when an oil-filled submarine cable is laid. CONSTITUTION:An oil-filled submarine cable 2 is laid with steps being provided with predetermined interval. When a fault such as damage occures in the cable between points A and B, oil in the cable is substituted by sea water at a point lower than a fault point 4, but the substitution phenomenon is stopped through the step arranged at point B and damage is limited within this range.

Filed: 1983-01-11
Abstract: PURPOSE:To make a photodetector compact to improve the visibility of driving, by interposing an aspherical cylinder lens between a slit plate of the photodetector and a photodetecting element. CONSTITUTION:The light from a projector 8 on the outside of a vehicle is made incident into a photodetector 1 through a window glass 13 and an infrared transmission filter 3 of the photodetector 1, and the incident light is led to a photodetecting element 5, which are provided in the depth, through a slit plate 4 and an aspherical cylinder lens 6.

Title: Formation of oxide film of platinum group metal
Inventor: TSUKADA KEIJI
IPC: C07C39/14
Filed: 1985-01-11
Abstract: PURPOSE:To form the oxide film of the platinum group metal itself with good reproducibility and controllability on the surface layer of said metal by driving oxygen ions by an ion implantation method to the platinum group metal at prescribed acceleration energy to implant the ions to the concn. of a prescribed value or above. CONSTITUTION:O<+> ions are formed by the ionization of O2 by an ion source 1. The ions are passed through an ion lead-out electrode 2, a separating electromagnet 3 and a slit 4 and are thus made into the O<+> ion alone. The ions are then focused by a quadruple lens 6 at the acceleration energy accelerated to several keV-several hundreds keV by an ion acceleration pipe 5. The focused O<+> ions scan, for example, Pt10 of the platinum group metal via a scanning electrode 7 and a deflecting electrode 8 for the uniform implantation of the O<+> ions to the surface of the Pt10. The oxide film having >=10atom% O<+> ion concn. on the surface of the Pt10 is formed. The Pt10 is then taken out into the air and is heat-treated in an electric furnace in which an O2 atmosphere is maintained. The platinum group metal is preferably Ir, Rh, Ru and Pd in addition to Pt.

Abstract: PURPOSE:To use an input signal without reference to whether the signal is at an H or an L in the presence of it and at the L or the H in the absence of it, without using an external circuit, by setting or resetting an FF by an instruction. CONSTITUTION:When a power source VDD is negative one, an n type is employed as an MOS transistor TR19, and a p type is used as an MOSTR20. When an input signal is at an H in its presence, an instruction is set holding the real output of an FF30 at the H, and consequently TRs 19 and 20 turn on and off, respectively, so that an input terminal is held at an L when no signal arrives. When the input signal is at the L in its presence, the instruction is set holding the real output of the FF30 at the L, and consequently the TRs 19 and 20 turn off and on, so that the input terminal is at the H when no signal arrives. In a circuit which uses a negative power source VDD, a p type TR19 and an n type TR20 are used. In this case, when the input signal is at the H in its presence, the real output of the FF30 is held at the H and when at the L, its is held at the L.
