Title: Driving control method for microwave oven
Inventor: KIN KOUKON
IPC: F24C7/08
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To eliminate cooking deficiency due to excessive cooking of a food and prevent a heater from being driven for an unnecessary long period by driving a magnetron and the heater only for a maximum allowable time in the case where a weight of the food is lower than a minimum weight. SOLUTION: With a power source of a microwave oven turned on, a user puts a predetermined quantity of food into a cooking chamber and selects a desired cooking type. When a cooking operation is started by inputting a cooking start command, a weight WFOOD of the food is detected. A shaft 43 pushes a weight detector 45 by force as large as about the weight WFOOD of the food placed on a tray 12, thereby calculating the weight WFOOD of the food by comparing a waveform detected in a state in which no food is placed with an output waveform detected in a state in which the food is placed. Subsequently, the detected weight WFOOD of the food is compared with a preset minimum weight WMIN. If the weight WFOOD of the food is smaller than the minimum weight WMIN, a maximum allowable time TMAX when a magnetron is driven is set.  Consequently, the magnetron V6 and a heater 20 are driven only for the time TMAX.

Title: Method and device for measuring temperature using total area air/fuel ratio sensor
Inventor: KONDO TOSHIAKI
IPC: F02D45/00
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for measuring temperature by using a total area air/fuel ratio sensor by which the temperature of exhaust gas can be measured accurately. SOLUTION: A cell 10 is heated by a heater 70 up to a temperature in which the oxygen concentration can be measured, and when the cell 10 is heated by exhaust gas at the target temperature or higher, the temperature of exhaust gas is measured according to the resistance value of an electromotive force cell 24. At this time, since the resistance value of the cell 24 which is placed between a space 20 kept in a constant atmosphere and an oxygen reference chamber 26 with constant oxygen concentration, the resistance value can be measured accurately independent of the oxygen concentration in the atmosphere to be measured. Further, since the cell is heated by a heater and a temperature exceeding the target temperature is measured, high response can be established.

Title: Hood opening and closing device of dump truck
Inventor: NANUN DAISUKE
IPC: B60P7/04
Filed: 1982-03-10
Abstract: PURPOSE:To prevent a supporting frame from obstructing the opening motion of a side gate even when a hood is stored in a dump truck wherein a deck body having the side gate can be inclined to one side, by rotatably attaching the supporting frame to a part of the hood. CONSTITUTION:When a dump truck runs with a deck body 1 laded, an arm 21 which is rotatbly pivoted to a bracket 22 of a guide 11 is turned counterclockwise by a motor. Then, one end of a supporting frame 19 which is linked at its opposed end to the free end of the arm 21 makes an arc motion so that a hood 15 covers overall the top of the deck body 1. On the other hand, when the truck is unladed, the arm 21 is turned clockwise. Said end of the supporting frame 19 makes the arc motion reverse to said direction until the hood 15 is folded into two and stored, therefore opening the top of the deck body 1. In particular, for dumping the load to one side, for example, the deck body 1 is inclined to the side, and locks 8 are unfastened to open a side gate 7 on account of its own weight.
