IPC: A01N37/36
Filed: 1992-03-25
Abstract: PURPOSE:To obtain an antifouling agent effective for preventing the adhesion of aquatic organisms to ship bottom, fishing net, buoy, marine construction, etc., by using a 2-hydroxymonocarboxylic acid having high safety, antifouling effect on and repelling activity against noxious aquatic adhesive organisms as an active component. CONSTITUTION:The objective antifouling agent effective for preventing the adhesion and proliferation of harmful aquatic organisms can be produced by using a 2-hydroxymonocarboxylic acid originated from natural source, exhibiting high decomposability in natural environment and having high safety to human body and environment as an active component.

Title: Radiation sensor
Inventor: JIEEMUSU BUI HIYUUBAA
IPC: G01J5/02
Filed: 1988-03-22
Abstract: PURPOSE: To obtain a radiation sensor which can provide a radiation exposure data accurately for a long term while enduring all day exposure to sunshine and severe tropical weather by sealing a filter and a photocell hermetically. CONSTITUTION: The sensor comprises a housing, a filter 56, a photocell 57 arranged to detect a radiation passed through the filter 56, and means for receiving a signal designating the radiation. The filter 56 and photocell 57 are sealed in the housing by means of a hermetic seal 44. In order to enhance the detection accuracy and the service life of sensor, temperature of the filter 56 and photocell 57 is held lower than a predetermined highest level. More specifically, a thermoelectric crystal 68 is driven upon actuation of an apparatus to remove the heat from a block 16 and radiates the heat through a radiator 70. Furthermore, since the block 16 cools the wall of a recess 18, the filter 56 and photocell 57 are operated in cool environment even under direct sunshine and thereby a radiation exposure data can be provided accurately for a long term.

Title: Packaging structure of display device
Inventor: URANISHI KAZUO
IPC: H05K1/02
Filed: 1994-04-07
Abstract: PURPOSE:To prevent an increase in cost, to shorten the time for heating and to prevent mispositioning by a difference in the quantity of thermal expansion between terminal electrodes and wiring leads at the time of connection by providing a packaging structure with a heat transmission means having the higher thermal conductivity than the thermal conductivity of a base material in the parts to be connected to the terminal electrodes on the wiring leads. CONSTITUTION:This packaging structure is provided with an aperture 5a at the base material 5 in the connecting part of the wiring lead 4. Au auxiliary base material 8 to cover this aperture 5a is formed thin to have the higher thermal conductivity than the thermal conductivity of the base material 5. There is, therefore, no need for rising the temp. of a bonding tool too high when the wiring lead 4 is heated via the auxiliary base material 5 by the bonding tool. Setting of the temp. at 260 to 300 deg.C is possible. Consequently, the mispositioning by the difference in the amt. of thermal expansion between the terminal electrode 2 and the wiring lead 4 at the time of joining is lessened. Since the mispositioning is lessened to 5 to 20%, the frequency of maintenance of the bonding tool is lowered, the operating rate of equipment is improved and the stability of processes is enhanced.
