Disclosed is an aseismic support structure having one end secured to a fixed floor and another end connected to a subject structure placed on a floating floor. The aseismic support structure includes a toggle bar, an attachment section and a mounting section. The toggle bar has a universal joint at each end and is adjustable in its length to have a predetermined length. The universal joints are rotatable around axes in the horizontal and vertical directions, respectively. The attachment section is connected to the toggle bar through one of the universal joints, and has at another end a third universal joint comprising a vertical rotation section. A cantilever extends substantially parallel to the fixed floor, is connected to the attachment section by the third universal joint at one end and has a fourth universal joint at another end. The mounting section is connected to the cantilever by the fourth universal joint and secures the equipment.

An aseismic support structure which includes a fixed part which is attached to a stationary floor, an equipment connection part for holding part of the equipment and a moving part coupled to the fixed part and the equipment connection part and wherein the moving part is freely movable relative to the fixed part in any direction parallel with the stationary floor and the equipment connection part is freely rotatable about the moving part. The equipment can have a caster which is held by the equipment connection part. For a weak earthquake shock, a caster lock portion of the equipment connection part locks the caster of the equipment to prevent the movement of the equipment. For a stronger earthquake, resonance is prevented by the moving part moving in a direction parallel with the stationary floor, and for a ruinous earthquake the vibration of the moving part is absorbed by a shock absorbing member attached to the fixed part.

An electric current detector according to the present invention detects an amount of current flowing through a conductor inserted into a through-hole of the current detector. The current detector includes a magnetic core casing in which a ring-shaped magnetic core having an air gap is molded and a detector element holder made by resin on which a detector element such as a Hall element is mounted. The detector element holder is coupled to the magnetic core casing so that the detector element is correctly positioned in the air gap of the ring-shaped magnetic core. Since the detector element is exposed to the air gap without being molded by resin, the detection accuracy is not affected by temperature changes in the course of usage. The detector element holder is simply coupled to the magnetic core casing without using complex connecting members. Accordingly, the electric current detector is manufactured at a low cost.

In a light control device for a vehicle, a control portion determines whether an illuminance detected by an illuminance sensor reaches a first reference illuminance, and performs a turning on or off control of lights of the vehicle based on the determined result. When the control portion receives an external environment change signal from an environment change detecting means, the control portion uses a second reference illuminance higher than the first reference illuminance, instead of the first reference illuminance, and performs the turning on or off control when the illuminance detected by the illuminance sensor reaches the second reference illuminance. Accordingly, vehicle lights can be suitably turned on or off in accordance with an external environment of the vehicle.

A gas detecting apparatus includes a gas cell, a laser source, a light diffuser and a photodetector. The gas cell has a gas inlet hole for letting the target gas come inside and a gas discharge hole for discharging the target gas, and retains a target gas to be detected. The laser source emits coherent light into the gas cell in order to detect a concentration of the target gas. The light diffuser is disposed in the optical path of the coherent light output from the laser source to diffuse the coherent light, thereby eliminating coherence of the coherent light. The photodetector receives light diffused by the light diffuser.

An electronic system includes an electronic system cabinet housing at least one electronic system component and a power generation system. The power generation system includes a cooling system having a cooling medium that generates a cooling energy. The power generation system further includes a thermoelectric conversion element having a first side and a second side. The first side is in a heat exchange relationship with the at least one electronic system component and the second side is in a heat exchange relationship with the cooling medium. Heat energy generated by the at least one electronic system component raises a temperature of the first side and the cooling energy generated by the cooling medium lowers a temperature of the second side to establish a temperature difference. The thermoelectric conversion element produces an electro-motive force based on the temperature difference.

Blades are connected to the surface of a disk and slots are formed in the surface of a shroud, which is opposite from the other surface of the shroud where the blades are to be welded. The blades are arranged on the opposite surface from the slots and a laser beam is applied from the surface in which the slots are formed, to weld the shroud and the blades. Components are installed on the surfaces of the slots on the opposite side from the blades after the blades and the shroud in which the slots are formed are welded. Alternatively, the slots are filled with a material different from that of the shroud, such as a resin. With this configuration, distortion caused by welding heat can be reduced without degrading the fluid performance.
