Title: Frequency-voltage converting circuit
Inventor: SUGIMOTO IHEI
IPC: H03K9/06
Filed: 1979-04-24
Abstract: PURPOSE:To improve a conversion efficiency with a simple constitution by providing an output transistor and a smoothing circuit in the output part of a differential amplifier and providing a delay circuit in the input part. CONSTITUTION:The voltage waveform of the base of transistor (TR)7 has a time delay for the voltage waveform of TR6, namely, input signal source 5 due to delay circuit 11 consisting of resistance 9 and capacitor 10, and a different potential is applied across bases of TR6 and 7 only during time delay (t), and therefore, a signal waveform where the output voltage is lowered only during this time is obtained in the collector of output transistor 20. Then, the input signal waveform is converted to pulses of width (t) from edges of rise and fall of the input signal waveform, and the number of pulses generated within a fixed time is larger according as the frequency of the input signal is higher. Consequently, when the output voltage is smoothed by integrating circuit 4, the average output voltage performs the f-v conversion operation indicated by the function of the frequency. As a result, the conversion efficiency can be improved with a simple constitution, and the circuit can be made into an IC easily.

Title: Forming method apparatus for composite blade
Inventor: YAMADA TAKUO
IPC: B64C11/20
Filed: 1993-02-16
Abstract: PURPOSE:To lessen remaining bubbles by repeating the process of shutting off an outlet at resin injection discharging surplus resin after a specified time until bubbles are not contained in the discharged resin. CONSTITUTION:In a mold 1 for forming there occurs a portion (path) where resin flows easily and a portion (stagnation) where the flow is difficult, so that pressure difference locally appears within the mold 1. Then by closing an opening/closing valve 8 flow of resin stops and thus there is no pressure difference in the mold 1. Then, by opening the opening/closing valve 8 at a time when the pressure within the mold 1 is possibly uniform, resin in a portion where the flow is easy, flows to lower the pressure, so that resin stagnating in a portion where the flow is difficult is pushed out. Bubbles involved in the stagnant portion are thus discharged.

Title: Off-line sign recognizing method
Inventor: MORIFUJI TSUKASA
IPC: G06T7/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain recognition with a high recognition rate by using off-stroke data by performing the recognition by dividing into a time series one piece of stroke data obtained by connecting stroke data and off-stroke data together. SOLUTION: When characters are inputted to tablets 6 and 7, the time and coordinate points are recorded and the total time of the respective strokes is stored. Then the movement distances of the respective strokes are totalized to find the total stroke length. A number N for normalization is calculated from the total stroke length. Then a sampling interval is calculated. Namely, the coordinates of sampling points are calculated by dividing the total time by the number N and the movement quantities of the respective sampling points are calculated. The X and Y coordinates which are thus proportionally distributed are converted into fuzzy angle information.  The fuzzy angle information is represented as the grade of a membership function and the similarity to angle information of reference data that a writer has registered is found to decide whether or not the input is the registered sign of the writer.

Title: Paper pay-out control device
Inventor: MAEDA AKIRA
IPC: B65H7/06
Filed: 1984-03-16
Abstract: PURPOSE:To make it possible to reduce the rate of jamming, in a banknote pay- out control device, etc., by stopping the monitoring of transfer of papers subsequent to the frontmost paper of each paper group when papers are paid out with being abnormally close together or being overlapped together. CONSTITUTION:When banknotes are abnormally close together an inter-banknote counter 17 delivers a less count value so that the previous pay-out order of the banknotes is set on a lead-out pointer 14 before the pay-out of the banknotes is stopped, and as well the counter 14 is cleared while a termination counter 16 is set. Further, addition is made on an S2 counter 11 and the thus obtained count value is compared with the pointer 14 to carry out a distribution process. When the distributing point is attained so that both values are coincident together, an abnormal banknote counter 19 is added with ''1'', and then the recovery order of the preceding banknotes is set on an abnormal banknote lead-out pointer 15 to complete the monitor of banknote transfer in a discriminating section 2. Thus, it is possible to prevent the occurrence of jamming from being erroneously judged. Further, when two banknotes are paid out being overlapped together, the monitor of banknote transfer is similarly stopped.

Abstract: PURPOSE:To make it possible to maintain the fixed accurate rotational frequency of a turntable even in case of a change in the rotational frequency of a turntable driving motor and fluctuations of a load caused by variations in electric power supply, by forming an alternating magnetic field by an electromagnet responding to pulses of a fixed period. CONSTITUTION:Once transistor 5 only conducts by being supplied with pulses of fixed frequency, electric power is fed to one-side winding 91 of coil 9 to excite an electromagnet so that magnetic pole 101 on the center side of a turntable will be given the N polarity. At this time, magnetic-pole belt 11 on the turntable is so applied with force in the gap of the electromagnet that the center side opposing to magnetic pole 101 will have the S polarity. Next, once transistor 6 only conducts, electric power is fed to one-side winding 92 of coil 9 and the electromagnet is so excited that magnetic pole 101 will be given the S polarity, changing the magnetic field in the gap in direction by 180 deg.. At this time, magnetic-pole belt 11 is applied with force in the gap while the N pole is placed inside. Synchronizing with pulses, a magnetic field is formed in the gap and this is inverted at even intervals. For the purpose, the magnetic poles of belt 11 pass through the gap synchronizing with pulses so as to stabilize the rotational frequency of the turntable.
