Title: Ejector type cooling tower
Inventor: NAKAMURA HISAO
IPC: F28C1/00
Filed: 1980-03-14
Abstract: PURPOSE: To increase the cooling capacity of an ejector type cooling tower and to increase the range of operation temperature, by providing a by-pass passage in parallel to a load at a portion of a pipe for feeding water to circulation water injection nozzles that is opposed to an eliminator.  
     CONSTITUTION: Water supplied via a feed water pipe 6 to a load 7 by a pump 6 is carried via a feed water pipe 8 and ejected from nozzles 3 into a cooling tower 1. Here, if the amount of circulation water passed through the load 7 is changed, the flow rate of water passed through a by-pass pipe 9 is changed, so that the amount of circulation water passed through the pipe 8 and ejected from nozzles 3 into the cooling tower 1 is kept unchanged. Therefore, if the load 7 is reduced, a standard amount of water is always supplied as injection water. Thus, it is enabled to prevent degradation of cooling performance, to increase the temperature difference at the inlet and the outlet of the load, and hence to increase the range of operation temperature.

Title: Bactericidal lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J61/16
Filed: 1987-02-18
Abstract: PURPOSE:To obtain a bactericidal lamp with no change in its output of ultraviolet rays even if the ambient temperature is changed by converting luminescent lines of rare gas atoms into ultraviolet rays near 260nm having a bactericidal effect with phosphors. CONSTITUTION:Electrodes 30, 30' are provided on both ends of a discharge container 6 allowing ultraviolet rays near 260nm to permeate. When a discharge is performed across the electrodes 30, 30', luminescent lines of Xe of 147nm and 130nm are emitted by the discharge in the Xe of the low pressure. These luminescent lines of 147nm and 130nm are converted into the wavelength near 260nm with a remarkable bactericidal effect by phosphors 8 provided on the inner face of the container 6. Since the low-pressure discharge characteristic of Xe is not changed by the ambient temperature, ultraviolet rays near 260nm are not reduced regardless of the ambient temperature, i.e., at the low temperature and the high temperature. Accordingly, a bactericidal lamp with no change in its output of ultraviolet rays even if the ambient temperature is changed can be obtained.

IPC: G07B15/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an ETC(electronic toll collection) system which can accurately discriminates between an ETC vehicle and a non-ETC vehicle which are entering a lane. SOLUTION: This system changes the point for deciding that communication is established between high-speed travel vehicles and low-speed travel vehicles, and decides that communication is established at the position of a 2nd vehicle detector S2 for the high-speed travel vehicles and at the time when a time needed and sufficient for communication establishment elapses after a 1st vehicle detector S1 is passed by for the low-speed travel vehicles. In this case, the decision point is L1 away from the 1st vehicle detector S1. Even if a vehicle 37 enters the lane at a low speed, a following vehicle 38 never enters a communication area, so as ETC vehicle and a non-ETC vehicle can accurately be discriminated.

Abstract: PURPOSE: To ensure an effective etching of the Si 3 N 4  film with the high-temperature phosphoric acid by piling CVDSiO 2  on the metal film and then using the mask covering over the cavity in the metal film.  
     CONSTITUTION: Si 3 N 4 202 and Mo203 are laminated on P-type Si substrate 201, and then CVDSiO 2 204 is formed. A selective etching is given to film 204, and Mo mask 206 is formed with mask 205 to give etching to Si 3 N 4 . With this method, minute hole 207 and 207' of film 206 are blocked with film 205, and so no touch is given to Si 3 N 4  through the hole when Si 3 N 4  is etched via the high-temperature phosphoric acid. Thus, the stop-type etching is never caused. After this, substrate 201 is changed porous selectively in the hydrofluoric acid, and P-type layer 208 and 208' are formed by ion injection. Then oxide film 209 and 209' are formed through oxidation to obtain N-type layer 210. In such constitution, the pn junction features good characteristics with the reduced leak current.
