摘要： PURPOSE: To provide a temperature keeping and cooking device capable of performing an accurate control of a cooking temperature without moving a cooking container such as a pan and the like. CONSTITUTION: A gas table 1 is provided with an ignition switch 3, a grid frame 5, a temperature sensor 7 and a load sensor 9. In addition, the gas table 1 is provided with a setting switch 11. A user optionally sets a boiling time b1 after a temperature T of a main body of a cooking container 13 is not less than a first set temperature a1 and a temperature keeping time b2 in which the temperature T of the main body of the cooking container 13 is not less than a second set temperature a2 and is not more tan a third set temperature a3 every time a cooking operation is performed, resulting in that the user can control the temperature keeping and cooking operation. In addition, a presence or a non-presence of a cooking container 13 on the gas table 1 is discriminated by the load sensor 9 and this heating operation is stopped in the case the cooking container 3 is not present on the gas table 1.

摘要： PURPOSE:To detect automatically and early gas leakage and to estimate its amount at a gas piping in the upper stream of a gas meter. CONSTITUTION:A gas meter 20 is provided with a speaker 24 which emits sound wave toward upper stream side and a microphone 25 which detects the reflection wave, emitted by the speaker 24 and reflected in the gas supply system. A control part 30 compares the data of reflection wave detected by the microphone 25 when the gas supply system is normal with that of at inspection, and, based on the amplitude changes amount of waves appearing earlier than the reflection wave detected by the microphone 25 at inspection, gas leakage is detected and its position is estimated based on time sequence.

摘要： PURPOSE:To suppress interruption of a breaker due to overccurent, to allow a small current contract, and to lighten the load on an appliance due to turn ON/OFF of power while enhancing the operability. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle. When the detected current exceeds a contract current limit, the breaker 1 interrupts the adapter and if the contract current exceeds the limit even after interruption of all adapters, the breaker interrupts. The breaker makes a decision whether somebody is present based on the operating state of alliance and relaxes the conditions of automatic interruption control set for safety if some person is recognized. The alliances are interrupted only partially when the current exceeds the limit and if the contract current exceeds it continuously, the breaker functions to interrupt power in safety. Furthermore, since the conditions of automatic interruption control for safety are relaxed, long time operation is allowed to enhance the operability.

摘要： PURPOSE:To suppress interruption of a breaker due to overcurrent, to allow a small current contract, and to lighten the load on an appliance due to turn ON/OFF of power. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle, and a communication means is provided for a breaker 1. The breaker 1 stores the priority of interruption for the adaptor and when a detected current exceeds a contract current limit, the adapter is interrupted according to the priority. If the overcurrent is eliminated in the way of interruption, the adaptor is reset at that moment. If the current exceeds the limit even after interruption of all adapters, the breaker interrupts. Consequently, the appliances are interrupted only partially even if the current exceeds the limit and when the contract current exceeds continuously, the breaker functions to interrupt power in safety. Furthermore, various signals may be transmitted from the adapter to the breaker.

摘要： PURPOSE:To protect an electric appliance over-loading due to abrupt interruption of power thereto by interrupting power to preselected electric appliances when the total current exceeds a contact current limit. CONSTITUTION:Adapters 2 are provided for an air-conditioner 6c, a hair dryer 6d and a microwave oven 6e which do not cause serious trouble upon abrupt power interruption. When the total current exceeds a contact current limit, an interrupting mechanism built in the adapter 2 functions to interrupt power to the electric appliance connected with the adapter 2. If the total current does not drop below the contract current limit, a breaker 1 functions to interrupt power to all the systems. This system realizes efficient use of power without increasing the contract current limit while taking account of temporary increase of power.

摘要： PURPOSE:To avoid interruption by a breaker due to overcurrent, to allow a small current contract, and to prevent an accident of an appliance not turned OFF inadvertently. CONSTITUTION:An adapter 2 is connected between an appliance 6c which can be interrupted with an overcurrent and a receptacle. When a detected current exceeds a contract current limit, a breaker 1 interrupts the adapter current and if the contract current limit is exceeded even after interruption of all adapters, the breaker is interrupted. An allowable conduction time is set for the breaker or the adapter and it is interrupted when the working time of adapter exceeds the allowable time. Consequently, the appliances are interrupted only partially even if the contract current limit is exceeded and when the current exceeds the contract limit continuously, the breaker functions to interrupt power in safety. When the current flows longer than the allowable time, a decision is made that an appliance is not turned OFF inadvertently and power is interrupted automatically.

摘要： PURPOSE:To obtain a discrimination apparatus which can further classify gas appliances belonging to the same flow-rate classification and which can discriminate the gas appliances in more detail. CONSTITUTION:A gas supply pressure is changed actively by an active-pressure-change means 45. A flow-rate-ratio operation means 46 finds the ratio of a flow rate which flows in an appliance equipped with a governor out of the total gas flow rate on the basis of a gas supply pressure and a gas flow rate which are detected by a pressure detection means 41 and a flow-rate detection means 42 before and after a pressure change. On the basis of the ratio and the total gas flow rate, a flow-rate operation means 47 for appliances equipped with gas governors and appliances not equipped with the gas governors finds a flow rate flowing in the appliance equipped with the gas governor and a flow rate flowing in the appliance not equipped with the gas governor. A gas-appliance-attribute-information detection means 48 detects information on the attribute of a gas appliance other than the gas flow rate and the gas supply pressure. A discrimination means 49 discriminates a gas appliance by fuzzy inference on the basis of individual pieces of information from an individual-flow-rate operation means 44, the flow-rate operation means 47 for appliances equipped with gas governors and the applainces not equipped with the gas governors and the gas-appliance-attribute- information detection means 48.

摘要： PURPOSE:To improve both the workability and the safety by reducing the high pressure gas supplied to a governor unit from a gas supply source via a flow-in side valve down to a medium or low level by the governor unit and supplying this reduced gas to the demander side. CONSTITUTION:A flow-in side valve 17 which is connected to the flow-in side gas pipeline, a flow-out side valve 18 which is connected to the flow-out side of a gas pipeline 42, and a governor unit 16 which is connected to both valves 17 and 18 via a pipeline are provided in a watertight case 11 in an attachable/ detachable way. In such a constitution, the high pressure gas supplied to the unit 16 from a gas supply source via the valve 17 is reduced to a medium or low level by the unit 16 and supplied to the gas demander side. Thus such a governor device can be installed even in a narrow space in a simple way. Furthermore the maintenance of the device is facilitated together with improvement of its workability and safety.
