Title: Method for monitoring gas leakage
Inventor: NISHINO HARUO
IPC: G01M3/04
Filed: 1993-07-26
Abstract: PURPOSE:To rationally monitor the leakage of a gas proportionally to the leaking amount of the gas by processing measurement data from gas detectors and anemometers near or at the same location of the gas detectors and calculating the gas flux of each gas detector. CONSTITUTION:A data processor fetches gas concentration data from a gas concentration data collecting and storing device 1 and the wind speed data corresponding to each gas detector from a wind speed data collecting and storing device 2. When both data respectively fall within their measurable ranges, the processor 3 calculates gas fluxes by multiplying the data by each other. When the wind speed data are lower than the measurable range, the processor 3 calculates the gas fluxes by multiplying the measurable lowest wind speed by gas concentrations. In the case, a gas flux exceeding an alarm setting value is calculated except the case where the gas concentrations are lower than the measurable range, the number, etc., of the gas detector against which the high gas flux is calculated is displayed on a CRT display device 8.

Title: Motor speed controller
Inventor: NAKAMURA YUJI
IPC: H02P29/00
Filed: 1994-08-05
Abstract: PURPOSE:To obtain a speed feedback signal which has only a small deterioration in accuracy in a low-speed range and which has no phase lag by estimating the speed based on the positional information obtained from an encoder, etc., characteristics of a motor, and a torque command and finding a weighted running average of the speed using a calculating formula. CONSTITUTION:A control calculator 5 receives a speed command and a speed feedback signal vfb and then outputs a torque command (u). A motor 6, having a torque controller and a position detector, receives a torque command u (i) at the present time (i) and then outputs a detected value of position y (i-K) at a time KTs (K>=0, Ts: sampling frequency) before. A predictor 1 outputs estimated values of speed v* (i+m) from the present time to a time M samplings after based on a dynamic characteristics model of the motor 6, the torque command (u), and the positional information (y). A calculator 4 calculates a speed v (i-K) and a memory 3 stores speed v (i-m) till the time i-K from earlier M' samplings. Then, a calculator 2 calculates a running average using a formula including weight coefficients w, w' and obtains a speed feedback signal.

Title: Gas cooker
Inventor: NANGO HARUYUKI
IPC: F24C3/12
Filed: 1986-08-29
Abstract: PURPOSE:To contrive accurate automatic extinguishment by determining the intensity of flame while cooking by a judgement means, and, if the intensity is lower than the set value, raising the reference value for automatic extinguishment by a certain amount over the value corresponding to the automatic extinguishment temperature. CONSTITUTION:When the cooking temperature set by a switch 43 is attained after the ignition by a high-flame heating, a valve coil 29 is energized to close a thermo valve 22 to set the heating back to a low-flame condition. Having memorized the fact that the valve coil 29 was energized, a micro computer 36 sets a value theta1+DELTAtheta which is higher than the automatic extinguishment temperature theta0 by a predetermined value DELTAtheta. If the amount of cooking object is small, the temperature continues to rise even when the flame is set back to a low- flame, and when a thermistor 3 detects a temperature corresponding to theta0+DELTAtheta1, a relay switch 31 is opened to interrupt the current flowing to a coil 27 to close a safety valve 21 for the automatic extinguishment. In this manner, an automatic extinguishment can be performed when the temperature at the bottom of a pot actually became the automatic extinguishment temperature.

Title: Burner device
Inventor: TANAKA KAZUMI
IPC: F23D14/08
Filed: 1986-08-29
Abstract: PURPOSE:To reduce the fluctuation of electromotive force by forming a thermoelectric generation element with jointed N-type and P-type semiconductor elements, juxtaposing the thermoelectric generation elements in many a number in the opening of the burner body in its thickness direction, and by forming a groove which acts as a flame hole on either one or both sides of the joint of the thermoelectric generating element. CONSTITUTION:When gas fuel is supplied into the gas feed port 5 of a burner body 1, the gas in a mixing tube 4 is jetted out of grooves 10, 10... of thermoelectric generation elements 9, 9... and, upon ignition, it burns in the burning flame 18. Shorter sides 7', 8'... of the thermoelectric generation elements 9, 9... are heated to a high temperature by the combustion heat of the flame 18, while their longer sides 7'', 8'' which remain at a low temperature are cooled by the mixed gas flowing toward the opening 3 in the mixing tube 4 to cause the thermoelectric generation elements 9, 9... to generate an electromotive force. In this manner, the electromotive force can steadily be retrieved without being adversely affected by the swaying of the burning flame due to the wind or the like.

Title: Rice cooker
Inventor: NOGUCHI HIROYUKI
IPC: A47J27/00
Filed: 1994-08-30
Abstract: PURPOSE: To eliminate the nonuniformity of temperature inside a pan by forming a specified angle from the peripheral edge of a bottom wall part for the corn-shaped part of the pan and setting a separate distance between first and second heating coils more than the specified multiple of a separate distance between the pan and the first heating coil. CONSTITUTION: When heating is performed by a first induced heating coil 19 arranged from the peripheral edge of a bottom wall part 14b to a corn-shaped part 18, the corn-shaped part 19 forms the angle of 60 deg. so that a moving vector can be generated along the inner surface of the corn-shaped part 18 by properly balancing the buoyancy of heated water and cohesion. Therefore, a strong up current is formed along the inner surface of the corn-shaped part 18 and a current suitable for rice cooking at comparatively high circulating speed with less temperature nonuniformity can be provided. Besides, a separate distance Qc between the first induced heating coil 19 and a second induced heating coil 20 is set almost longer than the double of a separate distance Qn between a pan 14 and the second induced heating coil 19.  Therefore, a magnetic field caused by the first induced heating coil 19 is hardly interferred with a magnetic field caused by the second induced heating coil 20 and preferable heating distribution can be provided.
