Title: Digital signal receiver
Inventor: MIYAKE HIDENORI
IPC: H04Q1/45
Filed: 1985-05-29
Abstract: PURPOSE:To receive surely a pushbutton signal by providing a means for interpolating sampling data between a frequency separation means and a limiter and applying the processing after the limiter in a frequency higher than the sampling frequency of an input signal. CONSTITUTION:A pushbutton (PB) signal sampled in 8kHz by an A/D converter 1 passes through an HPF 2 and is separated into low and high frequency groups by BEFs 3A,3B. Then the signal is subjected to re-sampling at a sampling frequency 16kHz by interpolation devices 7A,7B to increase the sample number during one period of the PB signal. Thus, the PB signal is detected by applying the processing of LIMs 4A,4B, BPFs 5A-5H and DETs 6A-6H at a sampling frequency16kHz. Then the output square wave of the LIM 4A,4B approaches 50% duty to receive surely the PB signal.

Title: Endless belt for electrophotographic device
Inventor: ISHIZAKI SATORU
IPC: G03G15/20
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To bring a fixing roll into contact with the outer surface of an endless belt provided with a heat resistant elastic layer on the surface of a base substance film principally composed of heat resistant resin so as to guarantee long-term stability even in a system that a belt is made to travel by the driving of the fixing roll by setting the surface roughness of the base substance film within a specified range. SOLUTION: The base substance film 11 made of the heat resistant resin is set so that its thickness is 10 to 200 μ and the surface roughness Rz of the surface 111 is 0.1 to 50 μm. When the surface roughness Rz is <0.1 μm, an anchor effect is not satisfactorily presented, and when it exceeds 50 μm, it becomes a hindrance in the case of maintaining the strength of the film 11, and the ruggedness of the surface appears the surface of the heat resistant elastic layer 12. The layer 12 provided on the surface of the film 11 is set so that its thickness is 100 to 300 μm. When the thickess is <=100 μm, it is hard to generate strain for mixing a superposed color layer uniformly, and when it exceeds 300 μm, it is hard to mix the toner layer sufficiently because the strain gets insufficient under the same compression margin by a pressure roll.

Abstract: PURPOSE:To prolong the service life of a power supply battery by supplying only a boosting voltage to a synthesizer circuit by providing the synthesizer circuit and supplying power from a power supply circuit to this synthesizer circuit. CONSTITUTION:As an output voltage Vo of a D/D converter 102, when a display circuit 90 in a display mode is turned on, a first power supply voltage Va is outputted and when the display circuit 90 in a reception mode is turned off and a synthesizer circuit 200 is turned on, a second power supply voltage Vb lower than the first power supply voltage Va is outputted. When both the display circuit 90 in a holding mode and the synthesizer circuit 200 are turned off, a third power supply voltage Vc is outputted as a bottom voltage required for holding memory. Thus, when the synthesizer circuit 200 is turned on, the output voltage is dropped, energy consumption can be reduced for the lowered output voltage and the service life of the power supply battery can be prolonged.

Title: Fuzzy inference system

Filed: 1987-05-12
Abstract: PURPOSE:To improve accuracy of the inference result by using the theoretical value of each rule condition part as a weight and applying the weighted average to the manipulated variable of the conclusion result of each rule conclusion part for output of the final manipulated variable. CONSTITUTION:The input variable of a controlled system 4 detected by a sensor part 2 is supplied to each of rules 1-n of a rule part 11. The part 11 applies the rules in response to the input variable value related to each rule for output of the theoretical value Li and the manipulated variable Yi. A weighted average part 12 performs the calculation where the weighted average is applied to the variable Yi with the value Li used as the weight Wi for the groups of both values Li and Yi outputted from each rule of the part 11. Then the part 12 outputs the result of said calculation as the final operation variable. An operation value setting part 3 sets the output operation variable as the control value to be given to the system 4. Thus it is possible to avoid such a case where the priority is given as a weight depending on dispersion showing the ambiguity degree of the fuzzy set.

     CONSTITUTION: An ester, e.g. acetate, is obtained by the reaction of an olefin, e.g. ethylne, propylene, butene, and an aliphatic caaboxylic acid, e.g. formic acid, acetic acid, acrylic acid, in liquid phase at 15-300°C under 10-300Kg/cm 2  in the presence of a W heteropoly acid, e.g. silico tungstic aicd, phospho-tungstic aicd, or its acidic metal salt and water. The amount of water is 0.01-5wt%, preferably 0.1-3wt% to the total amount of the aliphatic acid and the water. The catalyst is so stable that the catalyst isolated from the reaction mixture can be recycled together with the unreacted carboxylic acid. The continuous reaction is also possible.  
     EFFECT: The reaction pressure can be reduced. This may be a merit on the point of the cost of equipments and the safety in work operation
