Title: Production of optical transmission coupler
Inventor: MIKAMI KAZUO
IPC: G02B6/13
Filed: 1982-08-10
Abstract: PURPOSE:To make coupling loss less and manufacture easy by emitting polymn. light to a coupling part to obtain high refractive index layers, irradiating fixing light thereto to obtain condensing means and coupling optical waveguides and optical transmission means by said condensing means. CONSTITUTION:An optical fiber 16 for input and optical fibers 17, 18 for output are placed on a plastic substrate 10, and a polymn. liquid is flowed to form a polymer film layer 11 united to each fiber. A glass mask having a pattern for optical waveguides is superposed thereon and polymn. light is irradiated thereto to form the core parts for the optical waveguides. When the polymn. light is made incident to the fiber 16, high refractive index layers 22, 23, 24, 25, 26 are formed. As a result, waveguide type lenses 19a, 19b, 19c are formed by said high refractive index layers. When the lenses 19a-19c are formed, UV light is irradiated over the entire part of the film 11 to fix and stabilize the same. The optical waveguides, the fibers 16-18 and condensing means 19a-19c are thus united to one body and an optical transmission coupler is perfected.

Title: Installation of defoaming agent and purification tank
Inventor: SATO HACHIRO
IPC: C02F3/00
Filed: 1991-06-12
Abstract: PURPOSE:To ensure that a manhole is installed not so as to allow a container of defoamer to stand in the way for internal inspection when the manhole is opened and also at a position where the defoamer is efficiently utilized by fixing the manhole with a defoamer arranged on the internal peripheral part. CONSTITUTION:A ring-like sponge R impregnated with a liquid-phase defoamer is installed on the internal peripheral part at the rising end of a manhole M using a double adhesive tape. At the same time, an injection aperture 5 is provided at four points where the aperture is oriented upward in the ring-like sponge R. A liquid-phase defoamer is injected through the aperture 5 so that the sponge is impregnated with the defoamer. That is, if the bubble comes in contact with the ring-like sponge R impregnated with the defoaming agent, the defoaming agent disperses in the bubble, so that the bubble can be prevented from coming upward the top of the manhole. Further, the generation of bubbles in the tank can be restrained under the effects of the spread foaming agent. As the space near the open part of the manhole is hardly occupied by the ring- like sponge R, the field of vision becomes large when the interior of the tank is inspected.

SOLUTION: When a radiation 2 having a spacious dose distribution enters semiconductor radiation detecting elements 3a-3i formed from semiconductors 13a-13i, such as silicon or the like, electrons and holes are generated in the semiconductors 13a-13i. A high voltage is applied on each detecting element 3a-3i from a high-voltage power source 6 to generate electric fields in each semiconductor 13a-13i, therefore, the electrons generated in each semiconductor 13a-13i flow toward electrodes 11a-11i and the holes flow toward electrodes 12a-12i, thereby an ionization current flows. A dose rate of the radiation entering the detecting elements 3a-3i can be measured from the current quantity.  In this case, operations of MOS transistors 4a-4i are controlled by a control circuit 5, and each current from each detecting element 3a-3i is outputted in the prescribed order at every prescribed time from an output terminal OUT.
