Title: Fsk demodulation circuit
Inventor: KANDA YUJI
IPC: H04L27/14
Filed: 1992-07-01
Abstract: PURPOSE:To reduce the distortion of a waveform detected by a band-pass filter or the like and to remarkably reduce the processing amount by executing the delay detection without the frequency shift of an input FSK signal. CONSTITUTION:The input FSK signal F is inputted to multiplier circuits 3 and 6 and to a delay circuit 1. The output of the delay circuit 1 is inputted to a multiplier circuit 4 and to a delay circuit 2. Further, the output of the delay circuit 2 is inputted to a multiplier circuit 5. Coefficients 8-10 are inputted to the other input of the multiplier circuits 3-5, and the results of the multiplication are inputted in an adder circuit 7. The adder circuit 7 adds the multiplication result of the multiplier circuits 3-5 and inputs an addition signal A being the result of the addition to the other input of the circuit 6. The multiplier circuit 6 executes the multiplication for the delay detection between the input FSK signal F and the addition signal A, that is, the detection multiplication, outputting a detection output D. A low-pass filter 11 eliminates the frequency component which is the double of the input FSK signal F by the detection multiplication included in the detection output D and outputs it as demodulation output OD.

Title: Differential type fire alarm device
Inventor: OKAYAMA YOSHIAKI
IPC: G08B17/00
Filed: 1988-07-14
Abstract: PURPOSE:To omit a large capacity memory by finding out a reference level by a weighted mean value and making it unnecessary to form a detecting level for a prescribed time or for the number of times to find out a mean value. CONSTITUTION:A fire alarm device having different detecting method can be obtained by changing the weight value N of weighted mean. Namely, when a large value is selected as the weight value N (e.g. a value corresponding to the read sensor level for one hour), a reference level (a dotted line tauA) obtained by weighted mean shows a moderate change due to the variation of an environmental condition and the operation at that time is so-called constant temperature operation to be driven when the sensor level is changed from a certain steady value only by a prescribed width A. In this case, the reference level absorbs influence to be generated due to a long-time environmental change such as dirt and a temperature change between the daytime and night.

IPC: B21B37/00
Filed: 1984-08-23
Abstract: PURPOSE:To promote the increase in production capacity by providing the differentiator calculating the difference in the rolling reduction set value and the present value of the rolling reduction quantity and by connecting the rolling reduction calculating device of different accuracy with switching to a differentiator. CONSTITUTION:A rolling reduction position detector 7 detects the present value of the gap (d) between rolling rolls 1, 3 and rolling reduction setter 10 outputs the set value (ds) of the set roll intervals to a memory device 8. A differentiator 11 calculates the difference between the present value of the roll intervals (d) detected by the detector 7 and the set value (ds) and inputs into the rolling reduction speed arithmetic device 13 or 14 of lower accuracy and higher accuracy via a changeover mechanism 12. The rolling reduction time is shortened with said mechanism with performing the control of rolling reduction with using the arithmetic device 13 of lower accuracy for the initial several passes. The positioning of higher accuracy is then performed with using the arithmetic device 14 of high accuracy for the several last passes. Consequently, the dimensional accuracy of a rolling material is secured and the production capacity is increased by the shortening in rolling reduction time.

Abstract: PURPOSE:To assure as an SOI structure a MOS LSI using a trench gate and a trench capacitor by forming the SOI structure by implanting the side wall of a trench formed on an Si substrate surface with oxygen ions or hydrogen ions. CONSTITUTION:An SOI structure is formed at least in a trench by forming the trench section 2 from an Si substrate 1 surface by photolithography and dry etching, forming an ion implanted-layer 3 by implanting the trench section with oxygen by changing an angle of implantation, and forming an about 0.1mum thick Si film 4 at least in the trench section 2, and further changing the layer 3 to an oxide film layer by annealing. Once an oxide film has previously been formed on a surface or a flat surface outside the trench section 2, the surface of the layer 3 can be confined in the oxide film. Hereby, only the interior of the trench can be constructed as the SOI structure by later oxidizing only the portion of the film 4 outside the trench section 2. The trench SOI structure can be used as a gate section of a trench-gate MOS FET and a capacitor section of a trench-capacitor.

IPC: F16H59/70
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To cancel judgement processing of acceleration in a driving condition causing a wrong detection. SOLUTION: If an idle signal on flag FIDLON is equal to 1 or an idle signal off flag FIDLOF is equal to 0 when difference between atmospheric pressure PA and an atmospheric pressure initial value PAINT is less than 10mmHg and a starting acceleration counter value CSPD showing the judgement frequency of the acceleration of a vehicle is at 10 or more, an idle switch 17 is judged as an abnormal state, and a warning lamp is lighted.

Title: Thermosetting resin laminated sheet
Inventor: IKETANI KUNIO
IPC: B32B5/28
Filed: 1990-07-04
Abstract: PURPOSE:To make adhesion of plating extremely favorable, by forming a thermosetting resin laminated sheet where a base of a surface layer is comprised of at least a sheet of woven fabric having a thickness of 100mum or thinner and the central layer is comprised of at least a sheet of woven fabric or nonwoven fabric having a thickness of at least 150mum. CONSTITUTION:A fiber base is impregnated with thermosetting resin, laminate molding is performed, the base of a surface layer is comprised of at least one sheet of woven fabric having a thickness of 100mum or thinner and the central layer is comprised of at least one sheet of woven fabric or nonwoven fabric having a thickness of at least 150mum. The whole thickness of the central layer is made thinner than the total of apparent thickness of the base constituting the central layer and a thermosetting resin laminated sheet is formed. Since the woven fabric having the thickness of 100mum or thinner for the surface layer is preferable for thinning of a wire of a circuit and making mount into high density, ordinarily even one layer is enough. Although even one layer is good for the central layer, in the case where a thickness of a laminated sheet is at least 0.5mm, the central layer can be constituted also of at least two layers.

Title: Memory back-up system
Inventor: MATSUSHITA TADAO
IPC: G06F12/16
Filed: 1989-07-05
Abstract: PURPOSE:To attain the effective use of a back-up battery power supply and at the same time to prevent the overdischarge by detecting the voltage of a battery of a back-up power supply and controlling the supply of power to plural divided memory blocks. CONSTITUTION:The detection voltage levels V1 and V2 of the voltage detecting circuits 4 and 6 of a battery 15 are increased with reduction of the DC output Vm of a power unit 11. Then the detection signals Da and Db of both circuits 4 and 6 are set at high levels. Therefore the transistors TR Q2 and Q4 are turned on and then the TR Q1 and Q3 are also turned on. Then the power of the battery 15 is supplied to the memory blocks 13a and 13b. When the battery power supply is carried on and the voltage of the battery 15 drops down to the level V2 of the circuit 6, the signal Db of the circuit 6 is set at a low level. Thus, the supply of power is stopped to the block 13b. As a result, the overdischarge is prevented and at the same time a back-up period can be increased.
