Title: Lateral insulated gate field-effect transistor and semiconductor substrate therefor
Inventor: MATSUMOTO SATOSHI
IPC: H01L29/78
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce internal power loss by providing a depletion layer spreading from a second single crystal semiconductor layer side toward a first single crystal semiconductor layer side with a p-type impurity concentration and a thickness sufficient for diffusing the impurities over the entire thickness of the first single crystal semiconductor layer. SOLUTION: When a high voltage is applied between a source electrode 51 and a drain electrode 52, a depletion layer spreading from a second insulation layer 5 side toward an offset region 16 is required to spread over the entire thickness of the offset region 16. The offset region 16 can be depleted over the entire thickness thereof by making thin the second insulation layer 5 without lowering the concentration of n-type impurities in the offset region 16. Consequently, the resistance is not required to be increased under a state where the source electrode 51 and the drain electrode 52 are switched on in order to increase the resistance of the offset region 16 and the internal power loss is reduced under the state where the source electrode 51 and the drain electrode 52 are switched on.

IPC: C21C5/38
Filed: 1979-11-10
Abstract: PURPOSE:To prevent the excess suction of external air and the jet of exhaust gas to improve the recovery efficiency of CO gas by detecting slag level in the furnace during the period of recovery of the exhaust gas and carrying out the interruption control when the detection value exceeds a predetermined value. CONSTITUTION:During the period of recovery of the exhaust gas of the converter 1, etc, the slag level in gas is detected as acoustic level in furnace by a sound meter 14 attached to an upper part of the hood 4. In the case where the slag level exceeds a predetermined value and foaming phenomenon is expected, the acoustic level detection value is fed to a slag level converter 15 to be processed as a signal. This signal is compared with a set value by a slag level difference detecting device 16. This difference signal is fed to a controller 11 and a control signal is fed to a servo device 13 as an interruption signal preceding normally to the control. Thus, a damper 12 is operated and the exhaust gas attaracting amount is determined. According to this method, the change in pressure in the hood is restricted to minimum.

Title: Microwave oven
Inventor: ICHIKAWA NOBORU
IPC: H05B6/68
Filed: 1984-07-11
Abstract: PURPOSE:To make it possible to use a simple and less expensive measuring mechanism despite of the usage of digital display by indicating ''approximately'' or its synonyms along with the measured value on the display means. CONSTITUTION:Under the no load condition of a turn table 4, a switch 7 is pressed to start the weight measurement. The oscillation frequency signal at this moment from an oscillation means 9 through a signal rectifying means 11 is counted and computed by a central arithmetic control means 12, and the weight is determined, for example, to be Wo. Next, an object to be measured is placed on the turn table 4, and the switch 7 is again pressed to measure the total weight of W1 of the table 4 and the object. Then, the subtraction of W1-W0 is done inside the control means 12 to compute the weight of the object to be measured. The computation result is supplied from the control means 12 through the matching means 11 to a display means 8. The display means 8 displays the weight as measured along with a word ''approximately''. By displaying ''approximately'' or its synonym along with the measured value on the display, a mechanism for precision weight measurement becomes not necessarily needed, allowing the usage of a simple and less expensive measurement mechanism.
