Title: Interpolating arithmetic unit
Inventor: TSUDA TAKU
IPC: G06F17/17
Filed: 1989-01-25
Abstract: PURPOSE:To prevent the accurence of an error in an interpolating arithmetic unit to be used for the cross fading operation of a dimmer by finding out the Y coordinate value of a point on a straight line passing the 1st point expressed by the 1st X coordinate value and the 1st Y coordinate value and the 2nd point expressed by the 2nd X coordinate value and the 2nd Y coordinate value. CONSTITUTION:In the case of finding out the Y coordinate value of a point of the straight line passing the 1st and 2nd points, the 1st Y coordinate value of the 1st point expressed by plural bits having the same number of digits is added to the complement of the 2nd Y coordinate of the 2nd point by the 1st adder 12a. On the other hand, a product value signal consisting of plural bits is read out from a ROM 13a in which the product value of the rate of the previously determined X coordinate value of the point of the straight line to the difference between the X coordinate value and the 1st X coordinate value and the output of the adder 12a and the Y coordinate value of the 1st point is added to the product value by the 2nd adder 14b to obtain the Y coordinate value of the point on the straight line expressed by plural bits. Namely, the prescribed data are read out from the ROM 13a in which multiplied values are previously stored and used so that operation can be executed only by processing the same number of bits.

IPC: F23N5/24
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain a combustor for an oil hot water heater in which good combustion can be sustained by detecting reduction of combustion quantity with time. SOLUTION: A decision is made that combustion quantity has dropped if the temperature of a vaporizer 21 detected by a vaporizer temperature detecting means 29 is lower than a second specified temperature and an abnormality signal is delivered to an indicating section 44 where combustion quantity drop is indicated and notified. Consequently, a user can take a countermeasure previously, i.e., a user can perform cleaning operation including removal of tar from the vaporizer 21 or a nozzle 23, and service life of the combustor can be prolonged. Furthermore, maintainability is enhanced because combustion quantity drop is indicated and notified when the temperature of the vaporizer drops below a second specified temperature being set higher than a first specified temperature required at least for combustion and a countermeasure canbe taken previously.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To increase high charging efficiency under a high temperature at the last stage of charging and accumulated amount charged, by including a step to charge by a first electric current value and another step to charge intermittently by a second electric current value bigger than the first electric current value. SOLUTION: Charging is started with an electric current value of 150A. Then, a battery temperature T is measured, and whether the battery temperature T is not less than 40 deg.C or not is judged. If the temperature is less than 40 deg.C, charging is continued with 150A. On the other hand, if the temperature is not less than 40 deg.C, the electric current value is raised to 450A, and charging is carried out intermittently afterwards. That is, when the battery temperature T rises for 2 deg.C, charging is once stopped, and when the temperature descends for 1 deg.C afterwards, charging is repeated again with 450A until the battery temperature rises for 2 deg.C. This action is then repeated, and whether the battery temperature T is raised to not less than 50 deg.C is judged, and if judged it is not less than 50 deg.C, charging is finished.
