Title: Optical head
Inventor: YONEKUBO MASATOSHI
IPC: G11B11/10
Filed: 1987-07-03
Abstract: PURPOSE:To contrive to make the device small in size by using a holographic element so as to divide a reflected light from a storage medium into two, receiving the lights by photoelectric converting elements and making the polarized axis of two polarized plates different from each other thereby simplifying the optical system. CONSTITUTION:The luminous fluxes 103, 104 being the result of two-division of a reflected light 101 from an optical storage medium by a holographic element 102 are collected by a condenser lens 105 and the light detected by polarized plates 106, 107 is received by photoelectric conversion elements 108, 109. In this case, the polarized axis direction of the polarized plates 106, 107 is not the same but arranged by a different angle obliquely with respect to the polarized direction of the radiated light from the optical head. Thus, the distance between two photoelectric conversion elements is made close and a magneto- optical signal is obtained by a 2-split photodiode 315. Thus, the optical system is simplified and number of condenser lenses is reduced by one more than that of a conventional device and the device is made small in size.

Filed: 1991-07-08
Abstract: PURPOSE:To suppress noise generation during travelling and also to make the car compact through simplification of the structure of a driving device by driving the monorail type inspection car, which performs inspection of apparatuses located in the places where men can not approach like a nuclear power station and the like during running. CONSTITUTION:A monorail type inspection car 10 travels vertically and horizontally along a monorail 2 by transmitting driving force through pushing the monorail 2 by means of an ultrasonic linear motor 9 and a press ring 4. In this case, layered actuators 13 are mounted on the U-letter shape foot 12 of the ultrasonic linear motor 9, and the longitudinal vibration of the layered piezoelectric elements is transformed to the deflection vibration of the foot 12. And, by making a phase difference of the deflection vibration to be 90 deg. or -90 deg. simultaneously, multi-foot rabit-like movement or reverse directional movement is performed. By this constitution, it is possible to suppress noise generation during travelling to be low by omitting a speed reducing mechanism of a driving device, and also to make the car compact easily by simplifying its structure.

Abstract: PURPOSE:To call out an erroneous recognition pattern having the highest degree of resemblance and to delete it by using the character code of an input pattern which produces the erroneous recognition and a pattern to be deleted as an input to perform matching again likely at a recognition mode. CONSTITUTION:The resemblance is calculated between an input character pattern and each dictionary pattern in a dictionary 10 by a resemblance calculating circuit 5.

The result of this sorting is sent to a deciding circuit 9, and the extracted character code is sent to a display device. When an undesired pattern is selected and then deleted, it bears the highest resemblance to the input character pattern. In this case, the input character pattern retrieved out of a memory 6 by a misread input character number is sent again to the circuit 5 to delet the undesired character. Then the serial number of a pattern having the same character code as that to be deleted by a deletion control circuit 8 is selected out of the output of the circuit 5 to delete.
