Title: Field-emitting display element and method for controlling its brightness
Inventor: TANAKA MITSURU
IPC: H01J29/08
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To monitor the state of emission of a field-emitting display element and to hold its brightness constant by use of monitor outputs. SOLUTION: This field-emitting display element has a monitor anode 30 and a monitor cathode, both provided therein independently of a display anode 7, to which a phosphor layer 8 is applied, and a cathode array. The voltage of the monitor anode 30 becomes proportional to the amount of emission of a field-emitting element, and the difference between the voltage and a reference voltage 45 proportional to the emission current of the field-emitting display element in an initial state is output by a differential amplifier 48, so that in accordance with this output the anode voltage of the display anode 7 or a gate-emitter voltage to be applied to the display cathode array is controlled. The brightness of the phosphor layer 8 provided over the anode electrode 7 is thereby controlled to become the same as that in the initial state.

Title: Substrate for manufacturing josephson integrated circuit
Inventor: KATOU YUUJIROU
IPC: H01L39/22
Filed: 1983-11-12
Abstract: PURPOSE:To obtain the titled substrate satisfying various requirements thereto by using a fluorine compound of a metal as the substrate for manufacturing an integrated circuit employing a tunnel type Josephson junction element. CONSTITUTION:A substrate 1 for a Josephson circuit in which an Nb or Nb compound superconductor thin-film is used as a grounding surface 2 and a foundation electrode 4 is constituted from a metallic fluoride, such as LiF, NaF, KF, BeF2, MgF2, CaF2, SrF2, BaF2, YF3, ZrF4, HfF4, AlF3, TlF3, PbF2, SbF3, BiF3, LaF3, CeF3, NdF3, etc. Consequently, adhesive properties between a substrate 1 and the Nb group thin-film are improved, and the whole is divided easily into chip size. Even when a reaction is generated between an initial depositing layer of the Nb group thin-film and the surface of the fluoride substrate, a lower oxide of Nb is not formed because there is no oxygen on the surface of the substrate. The superconducting characteristics of the Nb group thin-film are not deteriorated because a fluoride NbF5 of Nb belongs to a sublimating gas and does not remain in the thin-film.

Abstract: PURPOSE:To elevate a base plate portion without a truck by supporting the base plate portion at a suitable height above the floor surface through supporting rods supported in a suitable turning state, inner wheels, rolling elements and outer wheels by an inter-locking driving mechanism. CONSTITUTION:When a crank handle 8 is turned to elongate an expansion driving rod 7, with a base plate portion 1 supported in a lower position, a left supporting rod 3a is turned counter-clockwise by a driving arm 6 and simultaneously a right supporting rod 3b is turned in the same direction by an interlocking driving mechanism comprising right and left interlocking arms 4a, 4b and an interlocking link 5. Right and left inner peripheral surface wheels 9a, 9b are also turned in the same direction as supporting rods 3a, 3b. As these inner wheels 9a, 9b are eccentric, the distances between the center of rotation, that is, the positions of the supporting rods 3a, 3b and points of outer wheels 11a, 11b, which are in contact with the floor surface 22 of a patient's room or the like are changed, so that the center of rotation is lifted up and the base plate portion 1 is lifted up through the supporting rods 3a, 3b and the supporting arms 2a, 2b. When the expansion driving rod 7 is shortened, the base plate portion 1 can be lowered by the reverse operation.

Title: Luminaire
Inventor: ENDO YOSHIMI
IPC: F21V23/04
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To secure a detecting range of a remote controller without impairing operability and an external appearance by installing a gathering member composed of an outward projecting mold part in the cover part opposed to the light receiving part of the remote controller receiving part. SOLUTION: A gathering member 35 composed of a mold part is installed in a cover or a V-shaped baffle main body 42 as the cover part opposed to the light receiving part 11 of the remote controller receiving part 10 so as to project downward from these. Thus, the gathering member 35 is not so bad in operability since a position of the remote controller receiving part 10 cannot not be specified by covering the remote controller receiving part 10 with a cover such as a shade so that a transmission signal transmitted from a remote controller can be easily picked up to decide a detecting range of the remote controller. Since the remote controller receiving part 10 is arranged in a position covered with the gathering member 35 and the V cover or the V-shaped baffle main body 42, an external appearance is not impaired.

Title: Dam fish way device
Inventor: TAKAHASHI TATSUNORI
IPC: E02B8/08
Filed: 1993-08-27
Abstract: PURPOSE:To guide fishes to the upper reaches of a dam without installing a long and large water channel. CONSTITUTION:Fishes which run up a river 2 are induced into a fish transfer vessel 9 in watertight structure. A door 23 of a fish entrance 21 is closed and then a lift mechanism 18 is driven, thereby lifting up the vessel 9 along a downstream side wall surface 1b of a dam 1. After the vessel 9 is halted at a position where a fish outlet 22 of the vessel 9 communicates with openings for water channels 5H, 5M and 5L formed in the dam 1, the fish outlet 22 is opened and gates 7H, 7M and 7L are also opened, thereby communicating with the vessel 9 and a dam lake 3 so that the fishes in the vessel 9 may swim to the dam lake 3. Since then, a proper time is selected when the fishes in the vessel 9 are assumed to have moved to the dam lake 3, and the fish outlet 22 is closed. The vessel 9 is lowered to the river 2 where the above operations are repeated. This repeated operation makes it possible to transfer fishes running up the river 2 one after another. Since the water channels 5H, 5M and 5L are installed so as to conform to three different stored water levels, it is possible to correspond to changes in the stored water levels in the dam 1.
