Filed: 1990-10-08
Abstract: PURPOSE: To improve transmission torque in a hump mode by crossing a sector portion formed between slits of each plate in a first plate group with a plate radial plane always at a same angle. CONSTITUTION: Many inner plates 7 axially movable in a certain limit are formed in a hub 2. These inner plates 7 are positioned alternately with outer plates 10 provided in a housing 3. The inner plates 7 and the outer plates 10 are relatively non-rotatably engaged with corresponding teeth 9 of the hub 2 through inner teeth 8 and corresponding teeth 12 of the housing 3 through outer teeth 11, and they are spaced by spacer rings 13. Sector portions 14 formed from slits of the inner plates 7 cross with a plate radial plane always at a same angle. One side of the inner plates 7 abuts to the outer plate 10, and axial component force applied to the plate improves transmission torque in a hump mode.

IPC: H03K19/14
Filed: 1985-11-29
Abstract: PURPOSE:To cascade a fundamental logic circuit as it is by obtaining the gain at the time when a semiconductor optical switch is in an on-state,without chang ing a light input level, against a change of an arithmetic function. CONSTITUTION:To input terminal I1, I2 an input optical pulse train is applied, and to an input terminal I3, '1' (a state that a prescribed light intensity input always exists, in case of a positive logic) is always applied. Only when '1' has been inputted to the input terminal I1, a semiconductor optical switch SW2 becomes on, therefore, an output of the semiconductor optical switch SW2 becomes '1', only in case both the input terminals I1, I2 are '1'. Accordingly, when the output of the semiconductor optical switch SW2 is seen, it becomes AND. In case semiconductor optical switches SW3, SW4 are in an on-state, an input optical signal is amplified and outputted as it is, therefore, an AND output of the input terminals I1, I2, and a NAND output are obtained in an output terminal O2, and an output terminal O3, respectively.

Filed: 1988-10-25
Abstract: PURPOSE:To realize high temperature resistance without using a beryllia ceramics by joining a thin alumina ceramic pipe into a metal pipe and by joining doughnut ceramic plates to both ends of the metal pipe. CONSTITUTION:An outer peripheral surface of an alumina ceramic pipe 1 and an inner side of a metal pipe 2 are joined and fixed by brazing, etc. Doughnut ceramic plates 3, 3' are also brazed to both ends of the pipe 2.
