Title: Led array head
Inventor: IZUMI YASUTAKA
IPC: B41J2/44
Filed: 1996-04-20
Abstract: PROBLEM TO BE SOLVED: To eliminate reflection of a radiated light on a substrate surface, make an emission pattern uniform, realize a higher density and a higher reflectance, and enable high-speed processing. SOLUTION: A reflector element 16 reflects a light radiated from an LED 13 into a substantially vertical direction. The reflector element 16 prevents a light emitted from a radiation end surface (active layer) from being reflected on the upper surface of a substrate 12, thus causing an emission pattern 17 to be uniform. This emission pattern 17 is condensed by an image forming optical element, such as, a rod lens array, so as to form a desired fine beam spot on an image surface. Consequently, a higher density at the LED array head is realized. The reflector element 16 uses AlGaAs which is the same material as the LED 13, thereby obtaining a high reflectance.

Title: Safety valve of enclosed lead storage battery
Inventor: TAKASU MASATOSHI
IPC: H01M2/12
Filed: 1986-05-28
Abstract: PURPOSE:To maintain the function of a safety valve, by fusing a film or sheet on a periphery of an exhaustion hole in a mold cap formed by injection molding, with a non-fused area partially left, to cover the exhaustion hole. CONSTITUTION:An exhaustion hole 7 formed in a molding cap 1 is covered with a film or sheet 3, and the periphery of the film or sheet 3 is fused on the molding cap 1 by supersonic or heat sealing method, with a nonfused area partially left. A gap is formed between the film or sheet 3 and the periphery of the exhaustion hole 7 outlet. A viscous liquid is injected into the gap and be held therein by an capillary action. A rise in battery internal pressure produces a gap between the battery and the liquid, and resultantly gases flow through the gap. On the other hand, a decrease in battery internal pressure causes the liquid to return in an original state by its molecular force, functioning to keep the battery in an enclosed state. The function of a safety valve can be hence maintained.
