Title: Microwave oven
Inventor: MIURA TAKASHI
IPC: F24C7/02
Filed: 1988-04-05
Abstract: PURPOSE:To prevent positively a humidity sensor from being damaged by an ignition by a method wherein a micro-wave oscillation means is driven and controlled in response to a detected humidity of the humidity sensor when the micro-wave heating is carried out and a driving control and supplying of air are stopped as a sensing temperature of a temperature sensor becomes an abnormal temperature. CONSTITUTION:As a micro-wave heating is specified by a key-board 10, a magnetron 2 is driven and controlled in response to a detected humidity of a humidity sensor 7. In this case, as a food is abnormally heated due to a certain cause and generates a fire, a temperature within a heating chamber is increased and reaches a predetermined abnormal temperature. This is detected by a temperature sensor 8; thereby, a driving control of the magnetron 2 and a supplying of air into the heating chamber 1 by a fan 4 are stopped. The predetermined abnormal temperature is substantially lower than 400 to 500 deg.C whore the humidity sensor 8 is damaged. The fire is rapidly diminished in response to a state in which the driving control and the supplying of air are stopped. Accordingly, even if the fire is generated, the humidity sensor 7 may not be exposed to 400 to 500 deg.C, an abnormal temperature, continuously and so there is no danger of damage.

IPC: B05D7/14
Filed: 1988-04-07
Abstract: PURPOSE:To prevent the nonuniform distribution of an electric current resulting from the resistance increase due to the consumption of a coating film and the variance in the film thickness and to exert a high-performance antifouling effect by setting a power source for applying a DC current in the direction of an electric conductor from an inner conductive coating film through an outer conductive coating film. CONSTITUTION:A DC current is allow to flow in the direction of a cathode 6 in seawater 2 from the inner conductive coating film 4 through the outer conductive coating film 5, hence the surface of the outer film 5 is covered with a dense chlorine film, and the deposition of marine organisms on the surface is prevented. The DC current in this case is supplied in the thickness direction of the outer film 5 through the base current of the inner film 4 having a low electric resistance from an electric terminal 4a provided to the inner film 4. Accordingly, even when the inner film 4 is consumed, the current density is not concentrated close to the terminal 4a, a stabilized uniform current density distribution can be maintained over a long period, and hence a high-performance antifouling effect can be exerted with low power consumption.

Title: Optical filter
Inventor: IWAOKA HIDETO
IPC: G02F1/055
Filed: 1981-06-01
Abstract: PURPOSE:To change a wavelength area of light passing through a substrate consisting of a photoelectric material by controlling voltage to be applied to electrodes formed so as to put the substrate between them. CONSTITUTION:Electrodes 2, 3 are fitted to the surfaces of a substrate 1 consisting of a photoelectric material and polarizers 5, 6 are arranged in a path of the light passing through the optical substrate 1 so as to put the substrate 1 between them. If voltage is applied from a driving circuit 4 to the substrate 1 through the electrodes 2,3, an electric field generated in the substrate gives the phase difference between vertical and parallel polarizing components against the electric field. Thus, when nonmonochromatic light is made incident from the side of polarizer 5 to the substrate 1, a wavelength area of projected light passed through the polarizer 6 can be optionally changed according to the value of voltage to be applied between the electrodes 2 and 3.

Title: Device and system for charging battery
Inventor: SAKAKIBARA KAZUMASA
IPC: H02J7/10
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To charge a battery in a short time while the temperature rise of the battery is suppressed. SOLUTION: The temperature rising pattern of a battery is retrieved from charging time based on the difference between the temperature of the battery when the charging is started and a target temperature value (S116). Then the battery is charged by adjusting the current value so that the temperature rise value may match the temperature rising pattern (S118 and S120). Therefore, the battery can be charged so that the temperature of the battery at the charging completing time may become the target temperature value (the lowest temperature) by optimizing the temperature rising pattern.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To enable a changing-over between a cooling operation and a heating operation to be carried out within a short period of time by a method wherein a flow of cold water and a flow of hot water are changed over without stopping a heating operation for working gas in a heating device. SOLUTION: As a cooling or heating changing-over operation is started when a heating operation is performed, a controller 53 sets a four-way valve 80 at a broken-line position, a heating device 56 is operated and then only a water pump P1 is stopped while He gas passing through a heater 7 is being heated. As the water pump P1 is stopped, the four-way valve 80 is changed over from its broken-line position to its solid line position, a water pump P2 is energized to cause cold water to be flowed in an indoor heat exchanger 16 in place of hot water. With such an arrangement as above, the heating operation is changed over to the cooling operation by stopping an operation of the water pump P1 and energizing the water pump P2 while the heated and ignited state is being kept.
