IPC: G06T7/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To make improvable the identification ability of paper sheets by controlling the number of neurons on the basis of the recognized result and reliability evaluation with respect to learning data. SOLUTION: Sampled paper sheet data are defined as data for learning, data preprocessing is performed to these data (S10), the coefficient of coupling is initialized (S20) and LVQ(Learning Vector Quantization) is executed (S30). When initializing the coefficient of coupling, the average value of input data corresponding to respective neurons is used. By learning the coefficient of coupling, a neural network is constructed, a threshold is prepared corresponding to the learning data (S40) and a neuron not to be ignited is excluded (S50). Next, the evaluation of the learning data and the check of neuron addition are performed (S60 and S70) and it is discriminated whether a neuron is added or not (S80). When no neuron is added, the threshold is expanded (S90). When a neuron is added, operation is returned to S30.

Title: Assembled pinion cutter
Inventor: FUJIWARA SEIJI
IPC: B23F21/10
Filed: 1984-09-07
Abstract: PURPOSE:To facilitate the securing of a tip to a tool body to reduce the working hours in order to reduce the cost, by fixing, to the tool body, a gear shape tip in which several gear cutters are integrally incorporated with a rotary member therearound. CONSTITUTION:A gear shape tip 12 in which cutters 12a for a tooth cutting process are integrally incorporated with a rotary member chip body 12a is brazed onto a shank 11 which is a tool body, and therefore, with the shank 11 and the gear shape chip 12 a pinion cutter 02 is obtained. That is, the pinion cutter 02 may be obtained only by one time of the process of brazing the gear shape tip 12 onto the shank 11, and the positional accuracy of the cutters 12a with respect to each other may be made high. Accordingly, the polishing margin of teeth upon blade-sharpening may be set to be minimum. Further, the shank 11 and the gear shape tip 12 are made into contact with each other through a wide contact area, and therefore, the attaching rigidity of the gear shape chip 12 is increased, so that the accuracy of cut materials may be easily maintained and as well the manhours for attachment may be also reduced.

Title: Rod coating application method and device therefor
Inventor: NARUSE YASUTO
IPC: B05C1/08
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of streaks, column-like unevenness, etc., by specifying the ratio of the contact length of a rod with a supporting body with respect to the circumferential longitudinal direction of the rod of a coating device. SOLUTION: The contact state is so set as to attain >=3% of the ratio of the contact length in the circumferential direction at which the rod 14 for the coating device comes into contact with a web 10 with respect to the circumferential length of the rod, i.e., the circumferential contact ratio. Since this contact ratio receives the restriction of a rod supplying member 18 and a weir plate 22, about 30% is an upper limit. The contact ratio in the transverse direction indicating the contact state of the rod 14 with the web 10 with respect to the width of the web 10 is specified to >=5%. About 95% of this contact ratio in the transverse direction is the upper limit in terms of a working method and working accuracy. The metering accuracy of the coating liquid amt. by a groove formed at the rod 14 is improved by setting the contact ratio in such a manner.  The generation of the stripes and unequalness is thus prevented.

Title: Tunnel transistor
Inventor: YAMADA TAKAHIRO
IPC: H01L29/739
Filed: 1983-10-05
Abstract: PURPOSE:To form a semiconductor element operating at very high speed by completely removing the effect of deceleration in a carrier travelling region except a tunnel barrier. CONSTITUTION:Degenerate semiconductors 101, 102 consisting of the same or reverse conduction type are formed on both sides of a non-degenerate semiconductor 105. Voltage V2 is applied between a source and a drain while voltage V1 is applied among gate electrodes 103, 103' and the source. Tunnel barriers are formed between the regions 101 and 105 and between the regions 102 and 105 by the application of the voltage. Consequently, the charges of a valence band in the region 101 reach to a valence band in the region 102 by a tunnel effect. Accordingly, the speed of a tunnel traisistor can be increased because the tunnel effect between the degenerate semiconductors is controlled by the nondegenerate semiconductor region and carriers are moved in a non-scattering manner.

Title: Fuel pump for car
Inventor: MATSUDA TAKESHI
IPC: F04D9/00
Filed: 1983-10-05
Abstract: PURPOSE:To prevent the vapor lock of a fuel pump by forming an increased flow-passage part where the sectional area of a flow passage is large onto the suction-port side of a pump flow-passage and forming a vapor discharge port on the reverse side of the suction port. CONSTITUTION:A pump flow-passage 46 has a ring form which leads from a suction port 1 to a discharge port, and the sectional area of the flow passage on the side close to the suction port 1, namely the sectional area of the flow passage on the relatively low-pressure side is increased, and an increased flow- passage part 46a is formed into circular form. A stepped part 46b is formed at the position where the sectional area of the flow passage is sharply reduced. Close to the stepped part 46b, a vapor flow-out port 6 is formed close to the inner peripheral side of the flow passage, namely to the inside of an impeller 32. Since said vapor discharge port 6 communicates to the inside of the flow passage 46 and the inside of a gasoline tank as the pump outside, vapor lock of a fuel pump can be prevented.

Title: Liquid jet recording method
Inventor: TAKAOKA MAKOTO
IPC: B41J2/205
Filed: 1986-08-08
Abstract: PURPOSE:To easily achieve representation of gradations, by providing a first heating step of simply applying thermal energy to a liquid and a second heating step of applying to the liquid thermal energy for forming a bubble. CONSTITUTION:Gradation data are set by a reverse current preventive diode 11, and a decremental counter 1 is set. Thereafter, a High signal is outputted from a comparator 3, and one pulse is generated by a one-shot phase generator 2 at the moment the counter 1 reaches zero. Then, a voltage value is determined through amplifiers 4, 5 connected in series with the counter and the pulse generator 2, and a desired waveform is synthetically formed at a terminal 01. A pulse width t1 is determined according to a set value of the gradation data, and the amount of a liquid droplet ejected is increased or decreased through the heat generation by a heat generating element according as the pulse width t1 is larger or smaller. The voltage of a signal corresponding to t2 exceeds an ejection threshold voltage, thereby forming an ejection timing for the liquid droplet. The liquid droplets thus formed are absorbed by a paper, thereby forming dots having different diameters. These operations are continuously performed, whereby printing with different dot diameters can be achieved.

Filed: 1987-07-28
Abstract: PURPOSE:To prevent erroneous detection of a level change point by deciding a level of an input signal sampled periodically and using it as a level change point when either of high/low discriminating times exceeds the majority. CONSTITUTION:A signal V enters a sampling means A, sampled at a prescribed period and its output is inputted to a level decides means B. The means B decides high or low level for the level of the inputted signal whether or not it is at a high or a low level at each sampling point of time and gives the result to a change detection means C. The means C applies the signal processing of the inputted signal. Then it is decided as a level change point when the result of decision of either the high or the low level exceeds the majority with respect to a prescribed number. Thus, the level change point is detected by the principle of majority. Thus, it is prevented that an erroneous level change point due to a noise superimposed on a signal is detected and a quick response is attained.

Title: Capacitor charging circuit
Inventor: MITOME MITSUO
IPC: H01G11/10
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit configuration of a capacitor charging circuit whiteout using any expensive parts by connecting a serially connected body of diodes in parallel with each capacitor and charging the capacitor to a voltage which is nearly equal to the forward voltage drop of the diodes. SOLUTION: For example, an electric double layer capacitor C is used as a capacitor to be charged. A charging circuit 20 composed of a serially connected body of diodes D1,..., Dn is connected across the capacitor C. The forward voltage drop of the diodes in adjusted to the breakdown voltage of the capacitor C in such a way that, when the breakdown voltage of the capacitor C is 2.4 V, the forward voltage drop is adjusted to 2.4 V by connecting the diodes in series. Since the breakdown voltages of the electric double layer capacitors C fluctuate, the forward voltage drop of the diodes are adjusted to the breakdown voltage of each electric double layer capacitor C by variously combining the diodes D1,..., Dn in accordance with the breakdown voltage.  When, for example, the forward voltage drop Vf of each diode is approx. 0.6 V, 2.4-V breakdown voltage Vc of the capacitor C can be obtained by connecting four diodes in series (Vc=4Vf≈2.4 V) and a value close to the conventional value Vc=2.5 V can be obtained.
