Abstract: PURPOSE:To improve deciding capability of similarity with respect to an input pattern by correcting a standard pattern. CONSTITUTION:A provisional standard pattern 25 of an expansion/contraction normalizing means 5 and a correction learning pattern 20 are sequentially inputted to the 2nd map function generating means 6. Assuming that the 2nd map function of each learning pattern and a standard pattern 14 is j=phi1(i), j=phi2(i)... phi5(i) in terms of the 2nd map function generating means 6, it turns out map functions 141, 142, 143 and 145, which are transmitted to the 2nd expansion/contraction normalizing means 7 as the 2nd map function 26. The 2nd expansion/ contraction normalizing means 7 has the same constitution as that of the expansion/contraction normalizing means 5, and the learning pattern 20 and the 2nd map function 26 are inputted to said means 5. By utilizing a map function j=phis(i), a correction learning pattern j=f1(i)...f5(i) is subjected to expansion/ contraction normalization, and j=fs(i)=fs[phis(i)] can be obtained.

IPC: H04Q3/58
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To enable registration, with which a call originating number is made correspondent to a terminal to be periferentially called, through simple operation by identifying the call originating number from a received signal, detecting a prescribed setting signal sent onto a communication line and correspondently registering the identified call originating number and the terminal sending the setting signal. SOLUTION: When a call is originated from the telephone set of caller on an outside wire 2, a call originating number identifying function part 102 identifies it and call terminating processing is started. A control function part 106 retrieves the call originating number from the list of relation between call originating numbers and terminal numbers stored in a storage device 108. Corresponding to a connecting terminal command, an exchange function part 101 connects the outside wire 2 and a terminal 50c. Wen a setting signal identifying function part 103 detects the setting signal, the control function part 106 judges whether the terminal responding to the incoming call is continuously kept in off-hook state later or not.  The control function part 106 correspondently registers the call originating number and a prescribed number corresponding to a terminal 50d on the list in the storage device 108.

Abstract: PURPOSE: To interrupt external influence to reduce distorsion and stress caused by heat and improve the accuracy by providing a resistive element formed by silicon variously doped in a deformed area under a conductive type layer. CONSTITUTION: A conductive path 9, a resistance element 3, a conductive type layer 8, an earthquake material 20, a frame 21 and the lower area of a deformed area are formed by silicon. Strong p-doping for forming the conductive path 9 is introduced into the surface of an n-doped silicon wafer, a p-doped silicon wafer or an n-doped silicon wafer, and further weak n-doping is introduced to form a resistive element 3. In this case, the layer 8 is disposed in such a manner as to have electric contact with n-material of the wafer. The deformed area 1 is not covered with a dielectric insulating layer 23. Accordingly, the bimetal effect produced by a difference in coefficient of thermal expansion between silicon oxide or silicon nitride for forming the insulating layer 23 and silicon can keep the deformed area from being deformed.

Filed: 1983-03-09
Abstract: PURPOSE:To detect the oblique movement of sheet surely in accordance with the output signal of a composing unit by composing the output signals of a pluality of sheet detecting units. CONSTITUTION:When a recording paper is running without moving obliquely, a plurality of optical fiber alleys 503 in the sheet detecting meanses arranged in parallel along the front rim of the recording paper are shielded simultaneously by the recording paper, as a result, the output of a photodetector 504 is reduced suddenly and a voltage V1, larger than the potential Vs of a reference voltage generator 605, is outputted from a differentiator 602 in an oblique movement decision device thereby indicating a normal running. On the other hand, in case the recording paper is running obliquely, the optical fiber alleys 503 are shielded sequentially, therefore, the output of the photodetector 504 is reduced gradually, the voltage V2, smaller than the same Vs, is outputted from the differentiator 602 and an oblique movement detecting signal 606 is outputted from a comparator 605 into a main control unit.

Title: Method for controlling temperature of hot water feeding device
Inventor: SEO MASAMI
IPC: F24H1/10
Filed: 1994-03-09
Abstract: PURPOSE:To perform an effective utilization of calorie during a gradual ignition period, and make fast a rising of hot water discharging characteristic by a method wherein a method for controlling a temperature of a hot water feeding device is carried out such that a water proportional valve is adjusted before a combustion operation is started and a flow rate of discharged hot water is limited for a period reaching a normal combustion, i.e., until a temperature of hot water discharging operation reaches a set temperature. CONSTITUTION:A water proportional valve is adjusted in such a way that a flow rate becomes F1 before a combustion operation is started. When a hot water feeding is started at the time t1, water of limited flow rate F1 flow in a water feeding passage through the adjusted water proportional valve. However, a time from the time t1 to t2 is a preparging period and gas is not yet supplied to a burner. Although the burner is ignited at a time t2 after the preparging period, a time ranging from the time t2 to the time t3 is a gradual ignition period and the gas proportional valve is gradually opened so as to cause a volume of gas at the limited gradual ignition level to rise from G1 to G2 during this period, resulting in that the flow rate is limited to F and so the hot water discharging temperature rises rapidly and a calorie during the gradual ignition period is effectively utilized.
