Title: Food heating device
Inventor: HOTSUTA KOUICHI
IPC: F24C7/02
Filed: 1980-05-15
Abstract: PURPOSE: To provide the food heating device wherein by switching a variable device in accordance with a selected heating system, a heating time and baking condition can be set by a single variable device, and once the variable device is set, any further operation is unnecessary, and further any damage which is likely to be caused by a misoperation to the food to be heated can be eliminated.  
     CONSTITUTION: When a cooking card is inserted into a card holder 5 and the card holder 5 is turned and then returned to the starting position, since the cooking card is not provided with, for example, a cut-off 6-d, only a grill heating switch 1-d is operated to be of level 1. A signal from this switch 1-d is converted into a binary code by a decorder 3-1 and then inputted into a control circuit 7 for the storing purpose. This signal of level 1 enters directly into a control terminal Y 2  of an electronic switch 9-2 to turn the terminal Y 2  to be ON, while it enters through an inverter 8 to a control terminal Y 1  of an electronic switch 9-1. In this instance, since the signal has been inverted to have level 0, the terminal Y 1  is turned to be OFF.

Abstract: PURPOSE:To prevent a semiconductor Al wiring from corroding due to highly dense phosphor in an interlayer insulation layer, by forming a polycrystal silicon film between an Al wiring and an interlayer insulation layer and providing an intermediate layer after oxidizing it. CONSTITUTION:A field insulation layer 12, an impurity diffusion layer 14 and a polycrystal silicon layer 13a for wiring are formed on a semiconductor substrate 11. A phosphor silicate glass interlayer insulation layer 15 is formed and a contact hole 16 is provided thereafter. The contact hole 16 edge is smoothed by heating and fluidizing. Next, a polycrystal silicon film 17 and a silicon nitride film 18 are formed. The silicon nitride film 18 masks the contact hole, and the other parts are oxidized to make an oxide film 17a. Next, a mask 18 is removed. An Al wiring 22 is formed to connect to the polycrystal silicon 17 at the contact hole. This prevents the Al wiring form conrroding, because the existance of oxide film 17a keeps the phosphor silicate layer 15 away from hygroscopicity.

Title: Underwater buoy waves meter
IPC: G01C13/00
Filed: 1992-03-24
Abstract: PURPOSE:To maintain measurement accuracy and achieve an accurate measurement by mounting an ultrasonic wave-height meter on an artificial horizontal stand which is mounted to an underwater buoy which is retained at one underwater point in tension. CONSTITUTION:This meter measures waves of water surface in a water region with a relatively deep part, an artificial horizontal stand 5 is mounted to an underwater buoy 3 which is connected to the top of a bridle 2 which is extended to an anchor 1 which is installed at a water bottom B, and then an ultrasonic wave-height meter 10 is mounted on the stand. The underwater buoy 3 which is retained at one point in tension under sea can cope with any water depth by changing the length of the bridle 2. Also, since the reception part of the ultrasonic wave-height meter 10 is located on the horizontal stand 5, the distance in vertical direction can be measured constantly even if the buoy 3 is inclined. When the buoy 3 is retained at a relatively deep position in tension, the buoy 3 does not rock even if waves approach a point on the water surface, thus minimizing influence to the measurement accuracy.

Abstract: PURPOSE:To reduce the necessary amount of operation by carrying out the detection of the dynamic vector in multiple steps. CONSTITUTION:The evaluating function is obtained at the 1st step for the 1st shift vector group which is displayed in A, B, C, D and E each, and then the shift vector featuring the minimum evaluating function is obtained among those in the vector group. Here if D is the vector to be obtained, the evaluating function value is obtained in the same way at the 2nd step for 2nd shift vector groups D1-D9 which are distributed near D. And then the shift vector featuring minimum evaluating function is obtained among the 2nd shift vector groups. And if D9 is minimum, the evaluating value is obtained at the 3rd step for 3rd shift vector groups D9.1- D9.9 which are distributed near D9. Then the shift vector featuring the minimum evaluating function is obtained. And if D9.5 features the minimum value, D9.9 is decided as the dynamic vector to the block. In this case, the signal of the preceding frame is shifted by vector D9.5 to be used as the predicting signal. Thus the differential signal of this predicting signal and the present-frame signal plus shift vector D9.5 are coded in the form of the dynamic vector to be transmitted.
