IPC: G03B21/11
Filed: 1981-09-09
Abstract: PURPOSE:To detect blip marks accurately with a set of sensor by generating a detection signal of the blip marks at the point of the time when the number of pulses generated at specified time intervals attains a prescribed value. CONSTITUTION:Clock pulses (c) are generated from an NAND gate GA1 corresponding to a high level signal detecting blip marks of prescribed lengths through a sensor from a terminal B and the synchronizing pulses proportional to film speeds and the blip marks are detected with FF1-FF4 of D type FFs of 4 stages or the like responding to the fall of the input pulses. The erroneous detection by dust, etc. shorter than the blip marks is prevented by such constitution whereby the detection outputs for the blip marks are generated after lapse of the specified time by the prescribed number of pulses according to film speeds and blip mark lengths, and the blip marks are detected accurately with a set of sensors.

Title: Superconducting magnetic device
Inventor: NISHIDA TAKAYUKI
IPC: H01F6/00
Filed: 1990-05-30
Abstract: PURPOSE:To achieve secure connection and disconnection between the superconductive coil of a superconductive magnet device and its power source and to make it possible to suppress external heat coming therein by relatively moving an outer member and an inner member to connect electric conductors of both members with each other and further by making the inner member contact with a fixed connector. CONSTITUTION:In order to disconnect a power source 8 from a superconductive coil 2, an inner member 27 is regressively moved outward from a low temperature container to disconnect a fixed connector 36 from the inner member 27. In such a state, a contact member 29 is positioned oppositely to each conductor 31 of the inner member 27, and external heat that conducts from the conductors 31 of the inner member 27 is isolated by an isolator 32. In order to connect a power source 8 with the superconductive coil 2, the disconnected inner member 27 is thrusted into the low temperature container 1 and moved forward. The inner member 27 thus moves forward while sliding on the contact surface of the contact member 29, and when the forward tip of the moving contact member 29 touches a lower plate 26, the fixed connector 36 is fitted into a hollow 44 of the inner member 27, thereby resulting in such a state that the conductor 31 is connected in series to the fixed connector 36 via a cylindrical electrodes 30.

Title: Field-effect transistor
Inventor: TOKUDA HIROKUNI
IPC: H01L29/80
Filed: 1993-06-15
Abstract: PURPOSE:To reduce gate length by forming gate electrodes on the side surface of a protrusion of an uneven part formed on a main surface of a compound semiconductor substrate. CONSTITUTION:When bias voltages are so applied that a source electrode 3 is ground, a drain electrode 4, is of a positive potential, and a gate electrode 5 is of a negative potential, a drain current flows from the drain electrode 4 to the source electrode 3, and is controlled by a depletion layer 6 stretching from the gate electrode 5. Since a semiinsulative substrate does not exist in a drain current path, the current component toward the substrate side, as one of short channel effect, is completely controlled. Since the depletion layer 6 under the gate stretches from both side surfaces of a protrusion, a channel thickness can be designed to be large. Thereby the short channel effect can be remarkably reduced. Since the gate length is almost determined by the trench depth of the unnvenness, an FET having an extremely short gate whose length is 0.1mum or smaller can be easily manufactured only by controlling the etching depth.
