Title: Heat exchange device
Inventor: KODERA TAKURO
IPC: F24F7/08
Filed: 1990-03-01
Abstract: PURPOSE:To enable a heat exchange device to be applicable for a housing wherein a distance between beams is low by a method wherein the direction of connection between a feed duct and a duct for exhaust is extended in parallel to a direction in which the partition plates of a heat exchange element are superposed with each other. CONSTITUTION:A fan 3 for feed and a fan 4 for exhaust are located approximately on the same axis, and a duct 9 for feed is also located approximately on the same axis. A duct 11 for exhaust is extended in parallel to a direction in which partition plate 6 of a heat exchange element 5 are superposed with each pother, and a distance between the ducts 9 and 11 can be set to a low value. This constitution also enables reduction of a lateral width E of a heat exchange device body 1. The partition plates 6 of the heat exchange element 5 are equalized in a whole area, and the number of the plates can be increased instead of reduction of an area per one plate. Namely, by increasing the length of the heat exchange element 5 in a longitudinal direction J of the heat exchange device body 1, a lateral width E of the heat exchange device body 1 can be further decreased.

Title: Fiber having rounded end and its production
Inventor: KIYONO MINORU
IPC: G02B6/32
Filed: 1988-03-04
Abstract: PURPOSE:To easily position a fiber having the rounded end and extend the distance between fibers having rounded ends by joining a transparent round bar-shaped member having a spherical front end face to the front end of the optical fiber and setting the distance from the junction surface to the front end face and the radius of curvature of the front end face so that the emitted light is parallel beams. CONSTITUTION:Since the round bar-shaped member is joined to the front end of a single mode optical fiber 1 and its front end face 2a is made spherical, a distance L and a radius R of curvature can be freely selected and a desired light beam state is obtained. When a multimode fiber 2 having the rounded and is used in a fiber type optical circuit after the distance L and the radius R of curvature are so set that the emitted light from the front end face 2a of the rounded end part is parallel beams, the coupling loss is kept very small even in case of the deviation of the position in the axial direction of the fiber 2 because the emitted light A is parallel beams. Thus, the fiber 2 having the rounded end is very easily positioned in the axial direction and the distance between fibers 2 having rouded ends is extended.

Abstract: PURPOSE:To shorten a photometric time, by performing reaction by dripping a sample to a measuring element 2 impregnated with a reagent and irradiating a light receiving element with auxiliary illumination when optical density is detected by irradiating the measuring element with photometric light in a photometric part. CONSTITUTION:A measuring element 2 impregnated with a reagent is successively inserted in a disc. Next, a disc is rotated at every one pitch to transfer the measuring element 2 to a sample dripping part where a sample is dripped to the measuring element 2 to perform reaction. Photometric light is emitted from a light source 54 passed through a lens 55 to be reflected by a mirror 57 and the reflected light is allowed to irradiate the measuring element 2 through an optical fiber 58. The reflected light from the measuring element 2 is transmitted to a light receiving element 6 through an optical fiber 59 to detect optical density. At this time, definite bias is applied until the reflected light is incident to the light receiving element 60 from an auxiliary illumination means 80 and illumination is interrupted at the time of photometry. Because the auxiliary illumination means is provided, the measuring element can be instantaneously measured and an analytical response speed can be increased.
