Title: Surface acoustic wave element
Inventor: EDA KAZUO
IPC: H03H9/25
Filed: 1994-03-15
Abstract: PURPOSE:To obtain a surface acoustic wave element which has a large electromechanical coupling coefficient and a small temperature dependence property by applying the flattening, specular surfacing, cleansing and hydrophilic treatments to the surface of each single crystal piezoelectric substrate and then applying the heat treatment to those piezoelectric substrates which are overlapped on each other. CONSTITUTION:A single crystal piezoelectric thin plate 20 uses the same material as that of a single crystal piezoelectric substrate 10 but is used by making thinner than the substrate 10 since the plate 20 functions to excite the surface acoustic wave. When a high frequency signal is supplied to a comb-line electrode 30, the surface acoustic wave is excited on a piezoelectric part near the electrode 30 and then propagated to a comb-line electrode 30' via a lamination structure. The surface acoustic wave is converted again into an electric signal by a piezoelectric part on the lower part of the electrode 30'. The single crystal piezoelectric substrates of the easy-to-handle thickness are prepared for both substrate 10 and plate 20. Then the flattening, specular surfacing, cleansing and hydrophilic treatments are applied to the surfaces of the substrate 10 and the plate 20. The heat treatment is applied to these substrate 10 and the plate 20 which are overlapped on each other for direct junction and for lamination. The plate 20 is made thinner by gring down to the prescribed thickness. The piezoelectric substance uses lithium niobate, lithium tantalate, lithium borate, a quartz, of etc., single crystal.

Abstract: PURPOSE:To judge easily the on-off state of a power supply switch, a tuning state, and a state of an in-use power source, by equipping a light emitting element, small current feeding circuit, large current feeding circuit, and intermittent current feeding circuit. CONSTITUTION:When the power supply switch SW of a radio part 3 is turned on, a small current is supplied to the LEDD1 through resistances R9 and R1 to turn on the LEDD1 in a dimmed state. Once the receiver is tuned manually, a voltage corresponding to the intensity of a radio wave of reception frequency is outputted from an AGC circuit 1 and divided by resistances R7 and R6 to apply the resulting voltage to the base of a transistor (TR) Q3; when it attains to a prescribed value, a TRQ4 is turned on through the TRQ3 and the LEDD1 increases in brightness. The output voltage of a voltage detecting circuit 2 is 0V while the voltage of the in-use power supply E is higher than an operation securing voltage, and once it drops below the operation securing voltage, a voltage VCC is outputted to allow an astable multivibrator AM to start operating for rectangular wave oscillation, permitting the LEDD1 to flash.

Abstract: PURPOSE:To dispense with the margin of a contact hole to conductor wiring layers and to contrive the improvement of the integration degree of a semiconductor integrated circuit device by a method wherein the surface of an interlayer insulating film covering the upper surface of the first conductor wiring layer is etched flat to the surface height of the first conductor wiring layer and after that, the second conductor wiring layer is formed. CONSTITUTION:A first conductor wiring layer 3 is formed on a semiconductor substrate 1 via a silicon oxide film 2. After an interlayer insulating film 4 formed with the aim of insulating from a second conductor wiring layer is grown on the layer 3, a photoresist 5 is applied in such a way that its surface is formed flat. The film 4 is flatly etched to the position of the surface of the layer 3 by an etchback technique. Moreover, a second conductor wiring layer 6 is formed, is patterned and the layers 3 and 6 are made to connect to each other without the intermediary of a contact hole. Thereby, the margin of the contact hole to the layers 3 and 6, which has been hitherto required in a semiconductor integrated circuit device, becomes unnecessary and the integration degree of the device can be improved.

Title: Boosted signal drive circuit
Inventor: MIYATAKE HIDEJI
IPC: H03K17/06
Filed: 1986-03-28
Abstract: PURPOSE:To prevent the level reduction of a word line by connecting an internal power supply having a prescribed level having a capacity being several times or over of a load capacitance of the word line and boosted to a potential or over of the word line to the word line at the same time when the word line is boosted or after that. CONSTITUTION:When a phiF signal goes to a high level, a voltage at a node (x) is discharged via a transistor (TR) 103 and a TR 102 is turned off. When the phiP signal goes to a high level after than, a node (y) is boosted to a power supply voltage or over (e.g., 8V) by the capacitive coupling. In this case, a word drive signal phiW is boosted to the power supply voltage or over (normally 7V) at the same time. When the potential of the word line is lowered by the capacitive coupling with the bit line after sensing, the phiW signal is brought into a level being the power supply voltage or over via a TR 105. In this case, since the capacity of the internal power supply VS is set larger than the load capacity of the word line by several times or over, the level reduction of the internal power supply VS is not almost caused. Further, the level of the internal power supply VS is kept always to the level of the word line or over.

Abstract: PURPOSE:To realize a separation of a satisfactory Y (luminance signal) and a C (color signal) by determining the selection of the result of plural arithmetic means in a digital color decoder with a correlation code word superimposed by the evaluating means of a digital color encoder. CONSTITUTION:The output of delaying devices 3 and 9 of a digital color encoder is added 10 and a correlation code word is superimposed and outputted to this in a superimposing circuit 11. The correlation decision necessary to superimposing is executed by inputting the output of a vertical correlation circuit 5 and the output of a horizontal correlation circuit 6 to a correlation deciding circuit 7 and outputting the decision result to a control circuit 13. A correlation code decoding circuit 20 of a digital color decoder controls a switching circuit 21, and by the result of the exclusive OR of the output of delaying devices 16 and 17, the output of a horizontal direction arithmetic circuit 19 or a vertical direction arithmetic circuit 18 is outputted. Thus, concerning two horizontal and vertical directions, a luminance signal Y and color difference signals I and Q are completely separated.

Abstract: PURPOSE:To make it possible to immediately input a character to the position outside a margin in connection with the operation of the key for releasing the margins, by setting and storing the moving position of a moving body outside a set moving range and controlling the movement of said moving body. CONSTITUTION:A carriage 4A is moved and left and right margin setting keys are pushed down to generate left and right margin codes which are, in turn, stored in a LM and RM storing memory apparatus 5 along with the position of the carriage 4A obtained from a carriage position detection apparatus 3 at this time. The position of the left side from the left margin and the position of the right side from the right magin are set and respectively stored in memory apparatuses 6, 7. For example, when the printing of one character is desired on the left and right margins, a margin release key is pushed down and a central processing unit 1 judges whether the present position of the carriage 4A detected by the carriage position detection apparatus 3 is equal to the left and right margins already set. When said position is equal, the carriage 4A is present on the left margin and the positions stored in the memory apparatuses 6, 7 are read to perform control so as to move the carriage 4A to said positions. By this method, a character can be printed at said positions by a character key.

Abstract: PURPOSE:To simplify the connection with a VTR to be measured and to simplify the overall structure of measuring instrument for recording/reproducing characteristics, by changing slightly the frequency within a range where the effect is reduced satisfactorily to the reproduction output in accordance with the change of a recording current. CONSTITUTION:When the characteristics corresponding to a curve 20, for example, is measured, an oscillator 14 and an attenuator 15 are controlled by a computer 18. Thus the frequency of a recording current flowing to a video head 4 is set at ...f1-DELTAf, f1, f1+DELTAf,... for a fixed period of time together with the current value set at ...-n, 0, n,...dB when the set level of the recording current of a head 4 set at 0dB. A series of such signals are recorded on a tape 3 via the head 4 of a VTR 1 and observed by a spectrum analyzer 16 through a reproduction amplifier 12. The display of the analyzer 16 is equivalent to a curve 20 when the observation is through with a series of signals. Thus the recording current/reproducing output characteristics can be obtained in the form of the curve 20 when the frequency is set at f1. So is with other curves 21 and 22. This omits the use of extra audio tracks, etc.
