Title: Drive for bicycle
Inventor: SUZUKI MASAKI
IPC: B62M3/06
Filed: 1987-11-10
Abstract: PURPOSE: To always apply torque to a crank without play part by arranging a speed variable interlocking means, by which rotational speed of a crank to a gear wheel is continuously varied from that for a predetermined section to that for the other section in a single rotation of the gear wheel. CONSTITUTION: When the shaft center of a planetary gear 10a on a crank 5a side is positioned at the top while the shaft center of a planetary gear 10b on a crank 5b side is positioned at the bottom, the cranks 5a, 5b are tilted forward by angles of θa deg., θb deg. respectively to their shaft centers of rotation if a cam followers 11a, 11b are positioned toward the body front side eccentrically to the shaft centers of the planetary gears l0a, 10b. Therefore, if either of the cranks 5a, 5b is rotationally driven from the position, in which the crank is rotated by an angle of θa deg. from the upper dead point, to the position before the dead point at an angle of θb deg., a gear wheel 8 is rotationally driven by 180 deg. respectively, so that the gear wheel 8 can be rotationally driven without generating any play section.

Abstract: PURPOSE:To improve the operability by recognizing characters in a device and storing the results to reduce the data volume to be stored and storing them in a memory of the device and eliminating a need of transfer them to the computer side at each time of read. CONSTITUTION:The image read by an image sensor 32 passes an amplifier 33 and is distributed and processed to binary data by a half tone processor 35 and is stored in an image preserving RAM 39. Characters are recognized by comparison with contents of a dictionary ROM 43 for OCR and the results are stored in the RAM 39, and they are displayed on a display device 2, and characters to be corrected are selected and correct characters are written on an input device 3 with a hand. These characters are compared with contents of a dictionary ROM 44 for OLCR; and if they are correct, correction object characters are changed. The results are stored in a work RAM 42 or an IC card 4. The data volume is reduced because stored data is not image data but character data, and data transfer to the computer is unnecessitated.

Abstract: PURPOSE: To enhance electron collecting efficiency and shorten the dimensions in the lateral direction and the long direction of a photomultiplier by constituting an input electrode with a truncated conical conductor, inside which an electron multiplier device having stack dynodes are arranged. CONSTITUTION: An input electrode 40 is constituted with a truncated conical conductor, inside which an electron multiplier device 50 having a stack dynode is arranged. Since the electron multiplier device 50 occupies a central position in a photo multiplier, the dimension in the lateral direction of the tube is shortened. When a potential V2 near a potential V1 of a photoelectric cathode 10 is applied to an input electrode 40, an electric field is produced mainly with a first dynode 51 in an input space 70 of the device 50, all photoelectrons 11 radiating form the photoelectric cathode 10 are caught with the dynode 51, combining of the photoelectric cathode 10 with the device 50 and the collection of photoelectrons 11 are increased.  Since the device 50 can be made to approach the photoelectric cathode 10 without disturbing electron collection, the dimension in the long direction of the tube is also shortened.

IPC: G06F11/30
Filed: 1986-11-29
Abstract: PURPOSE:To avoid the runaway or breakage of an equipment to be controlled when abnormality occurs by detecting the discontinuation of the CPU working and then restarting the CPU so as to not stop the operation of the CPU at the discontinuation of the CPU. CONSTITUTION:The discontinuation of the working of a CPU 10 is decided in case an external access is not given for a certain period of time or longer. Thus a restarting instruction is given to the CPU 10 from an abnormality detecting circuit 18 to avoid the long-time discontinuation of the CPU 10. The fact that the restarting instruction is executed is stored in a memory means and this memory contents are read out by the restarted CPU 10. In such a constitution, the CPU 10 can recognize that said restart is not carried out with normal application of a power supply but caused by the abnormality of a system. Thus the CPU 10 stops the operation of an equipment to be controlled or analyzes the factor of the abnormality based on a prescribed program. In such a way, the abnormal working or breakage of the equipment can be avoided.
