Title: Character reader
Inventor: NAGAI TOMIO
IPC: G06K9/03
Filed: 1985-01-31
Abstract: PURPOSE:To complete a reading job without stopping the actuation of a character reader despite the generation of errors by providing a reversible feeder device to a rejection table together with a selector guide and therefore attaining the feed of slips to a reading part from both directions. CONSTITUTION:When a reading error occurs, a slip 2 is led to a rejection table 10 by a selection guide 8. While the slip 2 is sent to a stacker table 9 when it is read with no error (Fig. A) The slip 2 having a reading error is taken into a character reader after al reading jobs are through at a reading part 6. In such a case, the table 10 moves up and a feeder 13 and a dry blower 15 are turned toward an arrow head in Fig B. Then the part 6 performs the reading job. Hereafter the slips 2 read with no error are led to the table 9 by a selection guide 16 and then the slip 2 is sent to a hopper table 1 when an error occurs.

Abstract: PURPOSE:To make electrical spectrums coincident in density and to obtain a light frequency stabilized device high in stability of frequency by a method wherein an original signal and a modulated signal are electrically filtered, and a relative error signal is detected. CONSTITUTION:Lasers 1 and 2 contained in a feedback systems 3 and 4 respectively are directly modulated by an FSK modulating signal, the optical signals converted in intensity fluctuation through a Fabry-Perot resonator 10 are detected by a photodetector 11, and the detected signals are added to the either input of mixers 5 and 6 after they pass through a low-pass filter 12. The signals obtained by making the FSK modulating signals which modulate the lasers 1 and 2 pass through a low-pass filters 7 and 8 possessed of nearly the same frequency characteristic with the filter 12 are added to the other input of the mixers 5 and 6. The mixers 5 and 6 have a function as a correlator and generate error signals correspondent to correlative frequency deviation from the resonant frequency of a resonator 10 of the light frequency of the lasers 1 and 2. When the error signals concerned are fed back to the drive current or the temperature of the lasers 1 and 2, the optical frequency of the lasers 1 and 2 is locked to the resonant frequency of the resonator 10.

Abstract: PURPOSE:To reduce the use quantity of a memory, to increase the storage capacity for display data which is high in necessity, and to shorten the wait time at the time of a glance at a program consisting of many pages by interrupting the storage of additional sound data, which is small in necessity as information in the majority of a program except KAR KARAOKE (recorded instrumental accompaniment) programs, in a memory. CONSTITUTION:When a read parameter is the additional sound data of a teletext including a data unit, the setting state of the reset flag of an additional sound deleting function by the specification of a remote control operating device 14 or key input part 12 is confirmed. When the reset flag is in a clear state, the storage of data following a data length code with length specified with a data length code in the RAM 8 is quieted. When the parameter is not the additional sound data, or when the reset flag is in a set state while the parameter is the additional sound data, the data following the data length code with the length specified with the data length code is stored in the RAM 8c in order. Consequently, the substantial storage capacity for data is increased and the wait time for teletext data to be sent next is shortened.

Abstract: PURPOSE:To prevent the lowering of the quantity of light due to oil, dust and the like, by arranging magnetic flux generating means at a specified space from a rotor so that an optical switch is connected to the output of a detection coil provided at the position where the magnetic flux of the generation means interlinks it to form a closed structure of the optical path. CONSTITUTION:A magnetic flux generating means 34 is made up of a permanent magnet 36 and a magnetic body 38 facing a detection gear 30. The magnetic flux of the means 34 interlinks the coil 40 to form a magnetic circuit and as the gear 30 turns, the movement of the gear part 32, the number of magnetic fluxes interlinked with the detection coil 40 changes to induce an AC voltage in the coil 40. The AC output is connected to a limited resistance 46 and a constant voltage diode 48 with leads 44 and 50. Then, a switch 42 is operated with a pulse voltage developing at both ends of the diode 48 and an intermittent signal of light proportional to the rotation of the gear 30 is converted into an electrical signal with a photodetector 64 through a optical connector 58 or the like to detect revolutions with a processing circuit 66. This optical path is so arranged in a closed structure to prevent the lowering of the quantity of light due to oil, dust and the like thereby enabling the maintaining of a highly accurate measurement for a long time.

Title: Block transfer system
Inventor: YOKOYAMA TOSHIO
IPC: H04L1/00
Filed: 1986-01-28
Abstract: PURPOSE:To avoid very simply a case that an end horizontal checking character comes to be wholly 0 and to decrease hardly the transferring speed for the checking effect by constituting all characters between the block of the data transfer and the block of all 0 bits. CONSTITUTION:A circuit GE 16 and a circuit GF 17 are added and the OR circuits of 8 bits of a circuit GD 15 are respectively changed from a 2-input to a 3-input. When a parity bit from a circuit GC 14 is wholly 0, an output 1 from the circuit GE 16 is given through the circuit GE 17 to the circuit DG 15 and all bits of the parity character are converted to 1. When all bits of the horizontal checking character come to be 0, it can be though that the probability to generate the error is very little in which all bits of the horizontals checking character come to be 1. Thus, even when checking is not executed by the above-mentioned means, the effect of the parity checking is hardly damaged.
