摘要:
A fluorescent lamp in which a connecting terminals of a lighting circuit board and lead wires of a fluorescent tube easily can be connected. The lamp includes a fluorescent tube, a holder holding the fluorescent tube, a lighting circuit board provided with a lighting circuit for lighting the fluorescent tube, and a case connected to the holder and housing the lighting circuit board. At the end portion of the lighting circuit board, V-shaped or Y-shaped cut-outs, which widen toward an outer side, are formed. In the vicinity of the inner narrow portion of the cut-outs, the connecting terminals connected to the lighting circuit are provided. On a side wall formed on the holder opposite to the fluorescent tube, V-shaped or Y-shaped cut-outs, which widen as the distance from said fluorescent tube increases, are provided, and the broad portion of the cut-outs of the holder and the broad portion of the cut-outs of the lighting circuit board are arranged facing each other. The lead wires of the fluorescent tube are connected to the connection terminals by welding.

A less costly bulb-shaped fluorescent lamp with improved assembly efficiency is provided which prevents the impairment of product quality due to the change in color of a holder or the slipping off of a fluorescent tube from the holder decreased in resin strength. The fluorescent lamp includes a set of fluorescent tubes, filament coils disposed at both ends of each fluorescent tube, a starter circuit for activating the fluorescent tubes, a holder for retaining the fluorescent tubes, and a case containing the starter circuit. The holder includes holes for receiving the fluorescent tubes, and a recess defined in a central portion of the holder and extended in the opposite direction of the fluorescent tubes.

A small fluorescent discharge tube and a bulb-shaped fluorescent lamp using the same with improved rise characteristics with respect to luminous flux in the case of a relatively short non-operation time of one to six hours after a stop of operation are provided. The fluorescent discharge tube includes at least three U-shaped glass tubes joined to form one body, electrodes provided at the ends thereof, and one discharge path formed therein. The fluorescent discharge tube further includes first auxiliary amalgams in vicinities of the electrodes, main amalgams placed at least in two locations in the discharge path between the electrodes, and a second auxiliary amalgam placed at least in one location between the main amalgams.

The present invention provides an inexpensive low-pressure mercury vapor discharge lamp having enhanced productivity. The low-pressure mercury vapor discharge lamp comprises an arc tube, a holder for holding the arc tube, a lighting circuit held on the opposite side of the holder from the arc tube and adapted for lighting the arc tube, a case having a screw portion provided at one end thereof and adapted for accommodating the lighting circuit, and a base threaded and fixed to the screw portion. A recessed groove is provided in a helical screw thread of the screw portion. The two lead wires (top lead wire and side lead wire) which are power source wires are respectively connected at one end thereof to the lighting circuit. The side lead wire is disposed along the groove and is sandwiched and fixed between the base and the screw portion.

A light-bulb-shaped fluorescent lamp accommodates in an outer housing that includes a transparent globe and a case, a bent fluorescent tube that has a pair of electrodes at both ends and contains an amalgam and a rare gas, and an electronic lighting circuit lighting the fluorescent tube. A light-bulb-shaped fluorescent lamp which has high conformity to regular light bulbs and realizes the same brightness as a regular 60 W light bulb while consuming less power than a conventional light-bulb-shaped fluorescent lamp is provided by setting the external diameter of the globe in the range of 55-65 mm, the total length of the globe in the range of 65-80 mm, the internal diameter of the fluorescent tube in the range of 7-11 mm, and the distance between the electrodes in the range of 200-280 mm.

A vehicle data analysis apparatus analyzes vehicle data that indicates chronological change of a vehicle state. The vehicle data analysis apparatus is provided with a computing unit and a recognition unit. The computing unit is configured to make obvious data fluctuation accompanying the development, in the vehicle data, of mechanical or control-related fault in a vehicle control system. The recognition unit is configured to recognize the vehicle data to be considered during vehicle fault diagnosis on the basis of a result of computation by the computing unit.

The present invention relates to auto-provisioning of authentication data for client devices. A registration server includes a gateway determination unit, which is configured to determine a gateway apparatus transferring a request signal from a device, and a processing unit. The processing unit is configured to transmit a first signal including a token and first access information of the gateway apparatus to the device if an identifier of the gateway apparatus is stored on the server, and to transmit a second signal indicating a positive response to the gateway apparatus when it obtains the token and the identifier based on a third signal received in response to the first signal. The gateway apparatus sends the secret value to the device when it receives the second signal.
