Abstract: A photopolymerization sensitizer may not cause problems of dusting or coloring of a cured product due to bleeding of additives such as the photopolymerization sensitizer on the surface, e.g., by blooming at the time of photo-curing or during storage of the cured product, and which provides a practically sufficient photo-curing rate. A 9,10-bis(alkoxycarbonylalkyleneoxy)anthracene compound having ester groups, of formula (I): wherein A is a C1-20 alkylene group, optionally branched by an alkyl group, R is a C1-20 alkyl group, optionally branched by the alkyl group, the C1-20 alkyl group optionally being a cycloalkyl group or a cycloalkylalkyl group, and X and Y are independently a hydrogen, a C1-8 alkyl group, or a halogen.

Abstract: An electronic apparatus includes a housing having a predetermined face; a power receiver that receives electric power in a contactless manner by way of the predetermined face; a secondary battery that is charged by electric power received by the power receiver; a front-back detection unit that detects whether or not the predetermined face faces a charger; and an alarm unit that notifies that the predetermined face is situated at a position inappropriate for charging when the front-back detection unit detects that the predetermined face does not face the charger.

Abstract: There is provided an electronic device for enabling the user to recognize the relative position of the electronic device to a power supply device such as a charger. An electronic device 11B includes a main coil 18 having a conductor wire wound around a main point 33 for receiving power for charging a secondary battery from a charger 12, a position detection coil 31 placed at a first point in the electronic device 11B, a position detection coil 32 placed at a second point in the electronic device 11B, and a position shift display section 39.

Abstract: A thermocouple (6) is provided for detecting a temperature of the tip of a needle electrode (1). The thermocouple (6) includes a tip connecting portion (18) where the tips of a pair of coated wires (8, 9) are electrically connected to each other and a tip coated portion where the tip connecting portion (18) is coated with polyolefin synthetic resin. The tip coated portion is bonded and fixed to the needle electrode (1). They provide a needle electrode device for medical application capable of being compact with the needle electrode provided with the thermocouple and of detecting a temperature using the thermocouple with high accuracy.

Abstract: A protective device for a hermetic motor-driven compressor comprises a protective device main body and an insulating layer made of a heat-resisting insulating material having a heat-resisting temperature of 155.degree. C. or higher, wherein the insulating layer surrounds the main body.

Abstract: A roller tunnel kiln includes a lower kiln body half composed integrally of a kiln bottom and a pair of transversely spaced lower kiln side wall halves which are made of refractory brick, a pair of endless chains disposed respectively on transversely opposite sides of the lower kiln body half outside thereof, the endless chains being movable forward along the lower kiln side wall halves at a height substantially equal to upper ends of the lower kiln side wall halves and movable backward along the lower kiln side wall halves at a height lower than the kiln bottom, a drive device for driving the endless chains in synchronism with each other, couplings mounted at regular intervals on link plates or link pins of each of the endless chains, feed members having opposite ends gripped by respective couplings and movable in a longitudinal direction of the lower kiln body half directly thereabove in response to the endless chains being synchronously driven, the feed members being made of a heat-resistant material and h
