Title: Electric water boiler with temperature control
Inventor: NAKAO YOSHITADA
IPC: A47J27/21
Filed: 1989-12-20
Abstract: PURPOSE:To prevent erroneous detection of boiling even if voltage is fluctuated to cause fluctuation in the ascending curve of water temperature or if gradually cooled hot water is heated and a bending point is generated on the ascending curve, by composing a device so that the boiling is effectively detected only when output is generated from a temperature comparing means. CONSTITUTION:In a nonvolatile storage means 6, the temperature data of previous boiling detection and the like are stored. Besides, according to the output of an atmospheric pressure detecting means 7, by a storage value correcting means 8, the storage value of said storage means 6 is corrected. The corrected temperature data and the output of a temperature detecting means 4 are compared with each other by a temperature comparing means 9, and when a difference between them is set to come within a specified value, then output is generated. Thus, by a boiling detecting means 10, it is discriminated to be boiling when both the output amounts of a gradient dulling detecting means 5 and the temperature comparing means 9 are obtained, and the electrification of a heater 2 is stopped, and at the same time, in the storage means 6, the output of temperature detecting means 4 is stored. A temperature at the time of previous boiling is kept stored, and in the area of a temperature lower than a temperature corrected according to atmospheric pressure, a device is composed not to perform the boiling detection 10, and so even if fluctuation and a bending point are generated on the ascending curve of water temperature due to the fluctuation of line voltage and the change of convection, the erroneous detection of boiling cannot be performed.

Title: On-off combustion controller for hot water supply device
Inventor: SUNAKAWA KAZUO
IPC: F24H1/10
Filed: 1987-12-25
Abstract: PURPOSE:To enlarge the range in which the discharge of hot water can be made and to prevent boiling, etc., by carrying out combustion when the quantity of water which is fed is over a required minimum quantity and stopping the combustion when a required quantity of heating is below the heat quantity of combustion of a burner and the temperature of the water is over a specified temperature. CONSTITUTION:When an inflow water quantity sensor 8 detects a water quantity over a beforehand specified minimum operation water quantity, the temperature of the water inflow, a set temperature of discharged hot water in addition to the water inflow quantity are read in a microcomputer 15 to calculate a required heat quantity per unit time. This required heat quantity is compared with the heat quantity of combustion per unit time at the lowest combustion capacity in a hot water supply device. If the required heat quantity is lower than the lowest heat quantity of combustion, the water temperature after the heat exchange is further calculated from the lowest heat quantity of combustion, the quantity of the water inflow, and its temperature. If the water temperature is over a maximum temperature (Tmax) which is beforehand specified, the combustion is no started. If the temperature goes over Tmax during the ON-combustion, the combustion stops. When the required heat quantity per unit time which was calculated is larger than the lowest heat quantity of combustion, a suitable combustion ON-time is selected from the required heat quantity and the quantity of the water inflow rate.

In a vertical blanking period TB, the switching part SW1 is changed over to the side of an output signal FO2 of a latch circuit LTH2 and the differential tabulating values of a TL period and TW period are separately read. Then, the values are separately stored in latch circuits LTH1 and LTH2 and output data are added in the adder AD1. Further, the data are stored again in a differential tabulating address part to correspond to the TL period of the differential tabulating memory M1 as the differential tabulating value of a first tabulating area T1.

Title: Voltage controlled oscillator
Inventor: HASHIMOTO HIDEO
IPC: H03B5/04
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To make a frequency change with respect to a control voltage constant even in the presence of a temperature change by changing the control voltage applied to a voltage varactor component depending on temperature to make a capacitance temperature characteristic of the voltage varactor component flat, where the capacitance of the voltage varactor component changes depending on the temperature of the voltage varactor component. SOLUTION: A control voltage Vc is divided by a resistance R(T) of a thermister 7 depending on temperature and a resistance R8 of a resistor R8, resulting in a corrected voltage Vc' expressed in expression: Vc'= R8/(R(T)+(R 8))}.Vc, which is fed to the varactor diode 5. Thus, the corrected control voltage Vc' depends on temperature (T) and the corrected control voltage Vc' changes when ambient temperature changes. Thus, the temperature versus capacitance characteristic of the varactor diode 5 can be made constant against the temperature (T), resulting that a change in the frequency with respect to the control voltage can be made constant against an ambient temperature change.

Title: Password dialing restriction device
Inventor: NISHIDA KOKI
IPC: H04Q3/58
Filed: 1992-11-18
Abstract: PURPOSE:To allow even a telephone set of a low-order class to make dialing as a telephone set of a high-order class. CONSTITUTION:A telephone set 6 of a class 1 whose international dialing is inhibited dials a password '*1234*'. Then a dial restriction control section 2 retrieves the password from password tables 3,4 through a control section 1. Since the dialed password is set to the password table of class 0, the dial restriction control section 2 recognizes it that dial data in succession to the password are data from a caller of class 0 and does not place restriction onto the control section 1. Thus, even telephone sets 6,7 whose international dialing is inhibited are able to make the international dialing.
