IPC: H04B10/00
Filed: 1985-01-16
Abstract: PURPOSE:To compensate any non-linear distortion of LED driving signals by a method wherein after rectifying the positive and negative side half-waves of LED driving signals and mixing both rectifying outputs with each other, compensating signals with signal wave form almost reverse to that of LED driving signals are transmitted as negative feedback to LED driving system. CONSTITUTION:Any positive side halfwaves of LED 18 driving signals are rectified by the first rectifying circuit 20 comprising diodes D1, D2 and any negative side half-waves are simultaneously rectified by the second rectifying circuit 21 comprising diodes D3, D4 while both rectifying outputs are mixed with each other by a variable mixed circuit 22 comprising a variable resistor etc. to form compensating signals with signal wave form almost reverse to that of LED 18 driving signals by means of adjusting the mixing ratio. Finally after reversing the phase of said compensating signals by a phase reversing circuit 23, a reversing input terminal 16b of a signal amplifier 16 may be inputted to constitute a negative feedback loop.

IPC: F27D7/06
Filed: 1978-01-25
Abstract: PURPOSE: Time-varing O 2  amount in a heating furnace is detected by O 2  probes installed in each furnacr zone, and the detected values are calculated using formulas and set to an adequate value, thereby to control O 2  amount in the zone at the most proper value.  
     CONSTITUTION: Actual O 2  amount is continuously detected from O 2  probes 3 installed in each zone of the furnace. The detected value is, through instructing adjusters 2, transmitted to the computer 4, which checks the value for its correctness. The computer stores two calculation formulas, one for normal stable furnace condition, the other for transit periods when the rate of fuel flow is caused to change suddenly by load variation or furnace temperature setting variation. The computer 4 treats the actual O 2  value using either formula depending on the value correctness or abnormality, and puts out an air-ratio instruction to the flow adjuster 5 for regulation.

Abstract: PROBLEM TO BE SOLVED: To provide a single-boiler twine-channel type water heater and a method for deciding a simultaneous use of hot water filling and supplying to decide whether the simultaneous use of the hot water filling and supplying is executed or not without providing a special purpose flow sensor. SOLUTION: A distribution ratio of a water flowing from a hot water supply channel 20 to a reheating channel 40 of a bathtub water in the case of dividing it to two ways is previously obtained and stored. Data representing the relationship among a supply heat amount from a burner 12, a heat absorption amount at the channel 20 side, a water temperature before reheating by a heat exchange 11 via the channel 40, and a flow rate of the reheated water flowing to the bathtub 30 is previously obtained and stored. An actual heat absorption amount at the channel 2O side is obtained from an input water temperature, output water temperature, and total flow rate.  And, whether the simultaneous use is conducted or not is decided by whether the relationship among the actual heat absorption amount, a burner supplying heat amount, a water temperature before reheating and single use of the hot water filling and a flow rate of the water reheated and flowing to the bathtub in the case of executing a single use of the hot water filling is coincident with that among the four parameters of the data previously stored.
