Filed: 1991-05-31
Abstract: PURPOSE:To achieve the accurate positioning of a long film by forming a plurality of through-holes to the long film at predetermined positions to detect the same by a plurality of the sensors provided to a measuring apparatus at predetermined positions. CONSTITUTION:Since a transmission hole 15 of a solution to be examined having an unused diffusion restricting film 16 provided thereto is exactly opposed to a spotting opening 20 at the point of time when the measurement of concn. of the previous time is completed, the solution to be examined can be spotted. Thereafter, a long film l is allowed to run by a motor 27 and a motor 27 is stopped by an ON-signal when a sensor 24a is exactly opposed to a through-hole 13a. At this time, the transmission hole 15 is exactly opposed to a measuring position 21a. When the measurement of concn. is completed, the film l is again allowed to run by the motor 27 and, at the point of time when the sensor 24a is exactly opposed to the end edge part of a through-hole 13b, the motor 27 is stopped. At this time, the next transmission hole 15 of the solution to be examined is exactly opposed to the opening 20. Since a sensor 24b is exactly opposed to the through-hole 13b in this state, a spottable state can be discriminated on the basis of the output signals from the sensors 21a, 24b.

Title: Combustion equipment
Inventor: TOMINAGA NAOTO
IPC: F23N5/02
Filed: 1995-04-28
Abstract: PURPOSE: To eliminate a variation in gas pressure through a changing-over at a combustion stage of a burner and improve a combustion characteristic by a method wherein a capability control data for increasing a value of driving current for a minimum opened valve as a combustion capability stage is increased in such a manner that a pressure of the burner and a gas pressure of fuel gas supplied may become the same to each other at a minimums combustion capability position at each of the stages. CONSTITUTION: A capability control data of each of the stages of a multi-stage capability changing-over type hot water feeding burner 2 is provided in such a manner that gas pressures of fuel gas fed into the hot water feeding burner 2 at each of the stages may become same to each other at a minimum combustion capability position. Then, they are arranged in such a manner that the gas pressures of the fuel gas fed into the hot water feeding burners 2 may become same to each other at a maximum combustion capability position. Thus, even if the capability changing-over of the burner combustion stage is changed over, a gas pressure controlling range may become the same range at each of the stage combustions.  Accordingly, irrespective of a state of the burner combustion stage, if a degree of opening of a proportional valve 13 is same, a load resistance of a single burner at the combustion surface may become same. With such an arrangement as above, a gas pressure supplied to the hot water feeding burner 2 is not varied and a superior combustion performance is realized.
