Title: Photocoupler
Inventor: KOSHIBA SATOSHI
IPC: H04B10/2507
Filed: 1986-07-17
Abstract: PURPOSE:To improve the efficiency of coupling between a light emitting element and an optical waveguide and between a light receiving element and a optical waveguide by adding lens coupling system to coupling between the light emitting element and the optical waveguide and between the light receiving element and the optical waveguide. CONSTITUTION:Beams (a) emitted and projected from light emitting element 3 are turned to parallel beams (b) by a collimater lens 13 and made incident upon a spherical lens 14. The spherical lens 14 converges the parallel beams (b) and projects the converged beams (c) to the end part 20 of a core 12. On the other hand, light transmitted through an optical fiber 11 is projected from a beam waist 16 to a space as optical beams (b). If positional relation (optical axis adjustment) is selected so that the beam waist 16, the center 15 of the lens 14 and the light receiving surface 17 of the light receiving element 4 are linearly arrayed, the optical beams (d) are converged by a spherical lens 15 and focused on the light receiving surface 17. The adoption of the collimater lens 13 and the spherical lens 14 makes it possible to execute photocoupling between the cores 12 of the optical fiber 11 extremely efficiently.

Title: Method for recognizing moving speed of image sensor
Inventor: TAKENAKA SHINYA
IPC: G06K9/20
Filed: 1984-08-10
Abstract: PURPOSE:To recognize the speed without malfunction by recognizing and updating the speed only when the second sensor detects a black picture element in the same position as the black picture element which the first sensor detects and removing black picture elements due to noise from the object of speed recognition. CONSTITUTION:When the first sensor S1 detects first a black picture element, the pattern at this time is latched in a shift register 1, and the register 1 outputs this pattern repeatedly in serial, and a timer counter 4 is started simultaneously with latching. AND between the output of the register 1 and the pattern of the second sensor S2 is operated, and the AND output is set to ''1'' only when they are ''1'' together, that is, the sensor S2 detects a black picture element in the same position as the black picture element which the sensor S1 detects. The timer counter 4 is stopped then to obtain the accurate passing time between sensors S1 and S2, and speed informtion is obtained. Thus, black picture elements are removed from the object of speed recognition, and the speed is recognized without malfunction.

Title: Automatic correction system of memory data error by microcontrol
Inventor: SUGAWARA YOSHINORI
IPC: G06F12/16
Filed: 1982-09-28
Abstract: PURPOSE:To eliminate the need for hardware for data correction by sending a request to resent the data to a CPU under microcontrol when a parity error occurs and correcting the data on the basis of it. CONSTITUTION:A read command for data a is outputted from a processor 9 to a memory 7. At this time, if a parity error occurs to the data A, the processor 9 sends a data request to a host CPU1 through a serial interface controller 5. The host CPU1 finds the data A and sends out the data A from the work station channel WSC4 of the host CPU1. The data A is stored in a buffer 6 through the serial interface controller 5. The data A stored in the buffer 6 is written in a memory 7 after the image explosion of print data in an image memory 8. Consequently, for the data A whose parity error is detected is written again by the same new data.

Abstract: PURPOSE:To perform both a demagnetization test and a package test with just a single device and to improve the operability of this tester device, by unifying a demagnetization tester and a package tester with common use secured for same components and at the same time having a loadable/unloadable structure for both a demagnetization program electric power supply and a demagnetization coil. CONSTITUTION:Both a demagnetization program power supply 34 and a demagnetization coil 35 can be loaded and unloaded and then loaded only for a demagnetization test. In the case of this demagnetization test, a demagnetization control part 31 is started and transfers the contents of a demagnetization test data part 32 to a program power supply part 16 to decide the current value of a bubble driver 18. In a package test mode a package test control part 13 transfers the contents of a package test data part 15 to the part 16 to decide the current value of the driver 18. Both exclusive data parts 15 and 32 are required for both demagnetization test and package test since the sequences are different from each other for measurement of characteristics. A read/write data part 14 and a data pattern generator 20 can be used in common with both tests.

Filed: 1990-06-29
Abstract: PURPOSE:To prevent the overlap of a retrieval processing by generating a clause candidate by means of processing operating in parallel in synchronizing with the extraction of a morpheme coincident to the partial character string of an input character string in an appearing order from the top in the input character string. CONSTITUTION:A multi-process means 4 retrieves the registered morpheme and generates the clause candidate by processes (types A and B) operating in parallel in synchronizing with the extraction of the morpheme coincident to the partial character string of the input character string the input character in the appearing order from the top in the input character string. The type A always exists one, and it generates the type B storing the morpheme inside when the morpheme comes to the top of the clause. The type B generates the type B connecting the morpheme at the end when it can be connected to the end of a morpheme string which the morpheme stores inside. The morpheme in which a plate detached back from the end position of the morpheme string stored inside is set to be the top is eliminated. The newly generated type B outputs the morpheme string as the clause candidate when the end of the morpheme string stored inside comes to the end of the clause.

Abstract: PURPOSE:To eliminate occupancy of a transmission line when a pattern with less change is consecutive in following to a rapid pattern change by allowing a packet composing circuit to form a packet from difference information at the transmission side and allowing a packet decomposing to reproduce the difference information at the reception side. CONSTITUTION:A television conference terminal device 100 at the transmission side uses a comparator circuit 3 to compare picture information picked up by an image pickup device 1 with picture information of a preceding frame stored in an image pickup pattern storage circuit 2. When difference information is a prescribed information or over, the difference information is formed into a packet by a packet composing circuit 11 and transmitted to a packet conversion network 10 through a subscriber terminator 4. When the device 100 at the reception side receives a packet from the device 4, the packet decomposing circuit 12 reproduces the difference information, a pattern synthesis circuit 7 synthesizes it with the pattern information stored in a received picture storage circuit 6 and displays the result on a receiver 5. The picture information synthesized by the circuit 7 is stored in the circuit 6 to prepare the synthesis processing with the next reception difference information.
