IPC: G21D1/00
Filed: 1985-03-30
Abstract: PURPOSE:To prevent heat from being generated and noises from being induced by fixing plural module bodies to a header plate in a sleeve, fitting plural optical connectors to both end plates connected to the module bodies, and supporting and connecting between optical connectors. CONSTITUTION:A module 18 has a joint pipe 21 with a flange 20 connected to the right end of its module body 19, an end plate 22 is connected to the joint pipe 21 airtightly, and an end plate 23 is connected to the left end of the module body 19 airtightly. An optical connector 24 is fitted to both end plates 22 and 23 and an optical cable 25 formed by bundling many optical fibers is connected between optical connectors 24 and 24 of both end plates 22 and 23. The optical cable 25 is supported at a specific interval by supports 26 extending from both end plates 22 and 23. Consequently, there is not any heat generation due to cable conductor resistance, so neither the number of cables used in each module nor the intensity of a light signal is restricted and there is no induced noise from outside or a contiguous cable.

IPC: F01C3/00
Filed: 1983-04-15
Abstract: PURPOSE:To raise the efficiency of a rotary engine, by employing such an arrangement that the lower portion of an eccentric part of a main shaft is pulled in the direction of rotation by the explosive pressure acted to a rotor through provision of an intermediate rotor shaft so that the rotational force, revolutional force and inertial force are all acted in the same direction. CONSTITUTION:A rotary engine, in which the apex portions of a trifoliate rotor 7 move along a helicoidal curve constituting the inner surface of a fixed outer casing 12 and the volume of the space defined between the outer casing and the rotor 7 is changed continuously, is designed to have an intermediate rotor shaft 5 disposed between an eccentric part 1 of a main shaft and the rotor 7 so that the upper portion of said eccentric part 1 as viewed from the side of explosive pressure s not pushed by the force applied to the rotor 7 but its lower portion is pulled in the direction of rotation. Resultantly, at the position about 20-90 deg. after the top dead point where the explosive pressure is high, the inertial force, rotational force and revolutional force are all acted in the same direction, so that it is enabled to obtain a higher thermal efficiency than a reciprocating engine.

Abstract: PURPOSE:To reduce the leakage current of a gate electrode so as to increase the breakdown strength of the gate electrode by providing the third semiconductor layer having an electron affinity which is smaller than that of the first semiconductor layer between the gate electrode and first semiconductor layer only at the section under the gate electrode. CONSTITUTION:The first semiconductor layer (channel layer) 1 and second semiconductor layer 2 are respectively constituted of undoped GaAs and n- GaAlAs, with the thickness and n-type impurity concentration of the layers 1 and 2 being made similar to those of conventional ones. An AlGaAs barrier layer 3 which is used as a barrier to electrons is provided between a gate electrode 6 and the channel layer 1 only at the section under a gate electrode section where a leakage current becomes an issue. Since no effect can be expected when the layer 3 is too thin in thickness and the distance between the electrode 6 and channel becomes longer and such element characteristics as transmission conductance, etc., deteriorate when the layer 3 is too thick, it is preferable to set the thickness of the layer 3 at about several tens of nm.

Title: Racing preventing circuit
Inventor: KUBOTA KATSUHISA
IPC: G06F1/04
Filed: 1988-03-23
Abstract: PURPOSE:To prevent racing at a reception latch by arranging a kind of a slave latch by using a clock pulse inverted before the reception latch or a clock pulse having a wider width than the width of a chop clock. CONSTITUTION:A latch (reception latch) 1 uses a chop clock with a small pulse width generated by chopping a supplied clock so as to fetch and store a data, and outputs it, while a latch (slave latch) 2 uses a clock with a wider clock width than the chopped clock width so as to fetch and store a data inversely from the phase of the chop clock and outputs the result to the latch 1. A clock chopper 3 generates a chop clock with a narrow pulse width from the clock. Since a time difference between clocks given the latches 1, 2 is large, the racing in the latch 1 is prevented completely.
