Title: Electric mosquito catcher
Inventor: NAMITE YOSHIHIRO
IPC: A01M1/20
Filed: 1987-12-08
Abstract: PURPOSE:To enhance vaporizing performance of insecticidal ingredients and reduce decomposition of the insecticidal ingredients, by setting the heating temperature in the central part of a heat radiating plate and a heating temperature difference between the central part and the peripheral part within respective specific ranges. CONSTITUTION:An electric mosquito catcher constituted of a heating unit having a thermistor, having positive characteristics and sandwiched between a pair of electrode plates and a heat radiating plate for carrying a larger mat than the heating unit. The heating temperature in the central part of the heat radiating plate is kept at 140-165 deg.C and the difference between the central part and the peripheral part is set at <=15 deg.C by a method for inserting a metallic plate having excellent thermal conductivity between the heating unit and the heat radiating plate. This catcher is especially effective in the case of an insecticidal ingredient-containing mat, such as furamethrin or prallethrin, readily causing decomposition by heating at high temperature.

Filed: 1988-12-08
Abstract: PURPOSE:To make it possible to prevent a thermal head from being broken by judging whether the current temperature is a temperature at which a line thermal head is to be operated for color development, based on an output pulse from an oscillation circuit the oscillational pulse period of which varies with temperature. CONSTITUTION:Before starting color development by operating a line thermal head 1, it is necessarily judged by a high temperature discriminating means 4 whether the color development by the head is to be performed. When it is judged that the color development is not to be performed, the color development by the head is stopped by a head color development stopping means 5, and the color development is suspended by a head color development suspending means 6 until it is judged by the means 4 that the color development by the head is to be performed. When it is judged by the means 4 that the color development by the head is to be performed, a color developing time for the head is determined by a head color development time determining means 7, and the color development by the head 1 is effected by a head color developing means 8.

IPC: G01T1/20
Filed: 1990-11-19
Abstract: PURPOSE:To let sample water be smoothly displaced within a detecting cell and detect radioactive rays without deteriorating measuring accuracy by forming densely a sample water passage in the detecting cell and flowing the sample water along this passage. CONSTITUTION:A flow cell 20 sets up an inflow port 20A and an outflow port 20 B of sample water. One flexible tube 22 is connected from the inflow port 2OA to the outflow port 20B. This tube 22 is arranged so that a vortex is formed spreading out to directions of the plane parallel to the plane in which a solid scintillator is combined. The sample water flows in from the inflow port 2OA, flows at an about constant speed inside the flow cell and arrives at the outflow port 20B. Thus, the sample water can smoothly be flowed without being stagnant in the detecting cell because the sample water passage is densely formed. As a result the unnecessary contamination within the detecting cell can be prevented while the measuring accuracy is improved.
