摘要:
A metal vapor discharge lamp comprises a discharge tube having a ceramic container into which a pair of electrodes and a discharge metal compound are sealed. The container comprises a first cylindrical portion, tapered portions, second cylindrical portions and third cylindrical portions. The third cylindrical portions are shrinkage-fitted to the second cylindrical portions. The electrodes are attached to the third cylindrical portion with a sealing member. An inner wall of the third cylindrical portions and the electrodes define a gap. The inner surface of the tapered portions and a central axis of the electrodes define an angle of 40°-80°. Thus, a metal vapor discharge lamp is provided whose discharge tube does not include disks among its parts, and which can maintain, over a long period of operation, good operating characteristics that depend only little on the lamp orientation.

A metal vapor discharge lamp having a highly reliable sealed portion. The lamp has an arc tube including a discharge portion of translucent ceramic in which a discharge metal is filled and a pair of electrodes is disposed; small tubular portions coupled to both ends of the discharge portion; feeder bodies inserted into the small tubular portions; and a sealing material sealing the gap between the feeder body and the small tubular portion at the end portion opposite to the discharge portion. The end of the small tubular portions and the inner surface of the discharge portion define a discharge space. The feeder bodies are composed of a conductive cermet and connected to the electrodes. The ends of the feeder bodies extend at least to the ends of the small tubular portions. The temperature of the end of the sealing material on the discharge space side during the lamp operation is not more than 800° C.

A metal halide lamp comprises a discharge tube of transparent ceramic in which a discharge metal is sealed, the discharge tube having a main cylindrical portion, ring portions provided at both ends of the main cylindrical portion, and tubular cylindrical portions provided at the ring portions; and a pair of electrodes inside the discharge tube; wherein a wall thickness .alpha. (in mm) of the main cylindrical portion satisfies the relation0.0023.times.W+0.22.ltoreq..alpha..ltoreq.0.0023.times.W+0.62,and a wall thickness .beta. (in mm) of the ring portion satisfies the relation0.0094.times.W+0.5.ltoreq..beta..ltoreq.0.0094.times.W+1.5,wherein W is the lamp power expressed in Watt. Alternatively, the discharge tube is air-tightly enclosed in the outer tube; the outer tube is filled with a gas comprising nitrogen gas; and the wall thickness .alpha. (in mm) of the main cylindrical portion satisfies the relation0.0023.times.W+0.12.ltoreq..alpha..ltoreq.0.0023.times.W+0.62,and the wall thickness .beta. (in mm) of the ring portion satisfies the relation0.0094.times.W+0.3.ltoreq..beta..ltoreq.0.0094.times.W+1.5,wherein W is the lamp power expressed in Watt. Thus, a metal halide lamp can be obtained that has a stable lifetime and considerably increased lamp efficiency compared to conventional high-color-rendition high-performance metal halide lamps using a quartz discharge tube.

A modular television apparatus including a video display module, a tuner module, and a power supply module, the modules being releasably combinable in a variety of combinations. The tuner module is provided with a switch for controlling a supply of power supply voltage from the power supply module to the remaining modules. The tuner module has a casing including an elongated recess into which a telescopic antenna can be stored, the recess conforming to the shape of the antenna. Switches are disposed within the recess, some of the switches having an exposed surface that conforms to the contour of the recess. The video display module is provided with a circuit for controlling the supply of power to other circuits according to detection of input of audio/video signals to the display modules.

A tablet packing apparatus of the present invention have a tablet feeding section 2 for feeding tablets, tablet vessel feeding sections 3 for feeding tablet vessels 11, and a tablet packing section 4 for packing tablets fed from the tablet feeding section 2, into a tablet vessel 11 fed from the tablet vessel feeding sections 3. The tablet feeding section comprises a plurality of feeder vessels 36 for storing different types of tablets and a tablet conveyor 27 for conveying the tablets discharged from the feeder vessels 36, to the tablet packing section 4. In the apparatus, the following restoring process is executed. After the apparatus is stopped due to abnormality, the tablets remaining in the guide paths 31 and the tablets conveyor means 27 are conveyed to the tablet packing section 4 by the tablets conveyor means 27 to recover them into the tablet vessel 11 and then the tablet vessel 11 is transferred to the container chamber 6 of the storage shelves 1.

Disclosed is a divalent silver oxide cell having amorphous carbon and a current collector in the positive active material. Amorphous carbon is useful for quickly dropping the high voltage of the AgO which appears at the initiation of discharge to a lower constant voltage level. The current collector which is disposed in the positive active material reduces the internal resistance of the cell when operating at low ambient temperatures including room temperature.
