IPC: G01N27/06
Filed: 1991-12-12
Abstract: PURPOSE:To measure residual chlorine and a carbonic acid simultaneously even when the residual chlorine and the carbonic acid coexist in sample water being an object of measurement. CONSTITUTION:In a water quality meter, a flow passage of a separating part is parted by a gas permeation film and sample water is made to flow through one flow passage of this separating part, while a solvent having a prescribed conductivity is made to flow through the other flow passage. An acid solution is mixed in the sample water flowing through the flow passage on one side, a gas produced by a reaction with the acid solution is made absorbed in the solvent flowing through the flow passage on the other side, through the gas permeation film, and the conductivity of the solvent is detected by a conductivity detecting part. The separating part is constructed of a first separating part 11 and a second separating part 12. On the upstream side of the flow passages 20 on one side of these first separating part 11 and second separating part 12, sample water flow passages 24 having the same source are provided in branches and a filter part 15 absorbing residual chlorine is provided in either one of the branching sample water flow passages 24.

Title: Camera
Inventor: WATANABE AKIRA
IPC: G08B21/00
Filed: 1990-11-28
Abstract: PURPOSE:To reduce the cost of a circuit and to simplify the circuit by making the circuit multiple functions by using the reset input terminal of a logical circuit IC such as a CPU also as a function other than the detection of the tuning-on of a power source for the decision of battery check. CONSTITUTION:Since the outputs of voltage detection means 20 and 34 which detect whether the source voltage of a camera becomes a prescribed value or under or not are given to the reset terminal RST of the logical circuit 1 such as the CPU, the logical circuit 1 is reset when it is detected by the detection means 20 and 34 that the source voltage becomes the prescribed value or under. On the contrary, in the case that the CPU is reset by executing the battery check, it can be judged that the residual quantity of a battery is small. Thus, by using the reset input terminal of the logical circuit IC such as the CPU also as the function other than the detection of the turning-on of the power source and making the circuit the multiple functions, the cost of the circuit is reduced the circuit is simplified.
