Title: Temperature control in heating cooker
Inventor: KISHIMOTO SHUZO
IPC: F24C7/08
Filed: 1994-02-16
Abstract: PURPOSE:To optimize the ON/OFF period of heater excitation and a temperature amplitude with respect to an objective temperature by a method wherein a setting width of temperature between a first and second set temperatures is enlarged when the ON/OFF period of heater excitation is shorter than a set period. CONSTITUTION:An objective temperature is stored by a key input unit 3 as a heater OFF temperature while a data, obtained by decreasing one step, 1deg., for example, is stored as a heater ON temperature. On the other hand, the ON/OFF period of a heater such as more than one min. and less than two min. for example, is set in the ROM of a microcomputer 1 as the optimum value. When the heater 6 is excited and an input from a temperature sensor 4 arrives at the heater OFF temperature, the counting of the ON/OFF period of the heater is started and the heater 6 is put OFF. When an input from the temperature sensor 4 has become lower than the heater ON temperature, a program decides the result of counting of the ON/OFF period of the heater and when the result of counting is less than one min., the program increases the width of differential with respect to the set data.

Title: Manufacture of exhaust gas purification catalysts
Inventor: TAKAO HIROSHI
IPC: B01J23/44
Filed: 1987-01-30
Abstract: PURPOSE:To permit Pd particles to be supported by a carrier finely and uniformly by adding dimitrodiamine Pd to an aqueous nitric acid solution, melting it at 60-100 deg.C, applying it on the support after being cured and finally reducing the Pd compound on the support. CONSTITUTION:A mixture of Pd(NH3)2(NO2)2 and an aqueous nitric acid and an aqueous nitric acid solution added to the former is allowed to be melted within a temperature range of 60-100 deg.C. This solution thus obtained is allowed to be cured until its color changes from yellowish pale to reddish brown, then from reddish brown to dark reddish brown. For instance, in the case of Pd(NH3)2(NO2)2 containing 300g/l of Pd metal, it can be sufficiently cured at 80 deg.C for 9-15hr. Next, the aqueous solution cured completely is immersed in a carrier (e.g. aluminum carrier) to allow a Pd compound impregnated in the carrier to be reduced. Consequently, exhaust gas purification catalysts supported in the Pd particles finely and uniformly are obtained. The amount of HNO3 of an aqueous nitric acid solution in which Pd(NH3)2(NO2)2 is melted should preferably be within the range of 250g/l-450g/l.

Title: Loop control system
Inventor: KUROKAWA HIDEFUMI
IPC: G06F9/32
Filed: 1983-02-09
Abstract: PURPOSE:To improve the operation speed, by executing the operation control and the loop control independently of each other. CONSTITUTION:By the execution of a loop set instruction, the first operand is stored in a loop final address storage register 5. The second operand is stored in a loop counter 3, and the third operand is stored in a branch destination address storage register 2. Then, an address coincidence detector 4 becomes operation state. The detector 4 checks always the coincidence between contents of a counter 1 and the register 5 and counts down the value of the loop counter 3 by one if they coincide with each other. When the result is not zero, the output of the branch destination address register 2 is set to the counter 1 to execute the loop. Since the instruction in the loop final address can be executed in an operation processing part 6 during this operation, the loop control and the operation processing are executed in parallel.

Title: Hot-water boiler

IPC: F24H1/28
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of a bad smell by inserting a baffle plate into a flue and allowing the baffle plate to carry a catalyst for sucking and burning a non-burned gas constituent. SOLUTION: An exhaust gas that is generated from the flame of a combustion chamber 2 flows toward a smoke collection board while uniformly hitting against the inner wall of a flue 3 by a baffle plate 11 during the flow through the flue 3 being formed in a pressure vessel 4 and transfers heat to the baffle plate 11 or the inner wall of the flue 3. In this case, a temperature distribution in the flue 3 ranges from 1,000 to 200, for example, from the combustion chamber 2 at a right end to the smoke collection board at a left end. In this manner, the baffle plate 11 that is inserted into each flue 3 when a combustion gas flows from the combustion chamber 2 toward the smoke collection board carries a platinum catalyst 13, so that a non-burned constituent flowing into the flue 3 without complete combustion in the combustion chamber 2 is activated and burned by the platinum catalyst 13, thus weakening the bad smell due to a non-combustion gas.
