Filed: 1981-03-11
Abstract: PURPOSE:To record information on both sides of an original at a high speed, by recording the reverse surface of the original, read during the forward movement of a reader, at the 1st recording part, and the top surface at the 2nd recording  part. CONSTITUTION:Once a sheet-like original 2 comes into contact with paper feed rollers 4 and 6, a photocoupler composed of an LED34 and a photodetecting element 36 detects the insertion of the original 2, and paper feed rollers 4, 6, 8, etc., start rotating. Then, the front end of the original 2 is detected by said photocoupler, whose detecting signal is used as a synchronizing signal for recording. Then, the reverse surface of the original 2 is read at a reverse-surface readout position A, and its top surface is read at a top-surface readout position B.

Title: Distributed processing system for automatic vending machine
Inventor: YOKOYAMA HITOSHI
IPC: G06Q40/00
Filed: 1990-02-15
Abstract: PURPOSE:To easily decide whether a reconnected slave is the same as the preceding one or not at the time of its reconnection by storing the time when timer abnormality is released between a master and the slave as a collating cipher data. CONSTITUTION:At the time of releasing the abnormality of a timer A, cipher data formed by a cipher data forming means B are stored in the cipher data storing means D of the master M and the corresponding slave S (e.g. S1). When a connection detecting means C detects the reconnection of the slave S1 after disconnection, the master M compares whether the cipher data stored in the means D coincide with the cipher data transmitted from the slave S1 or not by a data comparing means E and the coincidence of both the data means the reconnection of the same slave S1. Thereby, the initialization of the slave can be made unnecessary.

Title: Ladder-type ceramic filter
Inventor: YOSHIDA TETSUO
IPC: H03H9/58
Filed: 1979-03-27
Abstract: PURPOSE:To improve a spuriousness by using vibrators, which utilize length vibration of rectangular plates of a ratio of length to width of 2 or more, as series resonators and parallel resonators of a ladder-type ceramic filter and by connecting capacitors to parallel resonators. CONSTITUTION:Plural series resonators 1 and parallel resonators 2 are combined to constitute a ladder-type ceramic filter, and piezo-electric vibrators which utilize length vibration of rectangular plates of a side ratio of 2 or more are used as both resonators. By setting the side ratio to 2 or more, the effective coupling coefficient can be 90% or more, and the area of the rectangular plate becomes one third or less of the area of a square plate, so that the filter can be small-size. Since the capacity ratio becomes large because the stopping attenuation quantity of the normalized filter characteristic is enlarged, a capacity about 10 times as large as the capacity of the series resonator is required for the capacity of the parallel resonator, and capacitor Ca is added in parallel to the parallel resonator. As a result, no spuriousness is generated from main resonance frequency 455kHz to 1MHz.

Abstract: PURPOSE:To shorten the response time, by discriminating the accepting method of service-in and the skew compensating method of data on a bus in both reading and writing operations and then sending back service-out to both operations in the optimum period. CONSTITUTION:The service-in SRVIN is always scanned in the case of a reading operation for a channel device which is connected to an input/output device via an input/output interface. Then the data on a BUSIN is taken into an internal buffer if the internal buffer connected to the BUSIN in 100ns after the rise of the SRVIN. At the same time, the service-out SRVOUT is sent back. In the case of a writing operation, the time is counted at and after an internal buffer connected to a BUSOUT becomes available. At the same time, the scan is started for the SRVIN to check whether the SRVIN is accepted or not at and after 100ns elapses. If the SRVIN is accepted, the SRVOUT is immediately sent back. Thus the response time is shortened.
