IPC: F16C5/00
Filed: 1978-01-25
Abstract: PURPOSE: To permit mounting and removal of a piston with respect to a crosshead simply, reliably and speedily with such an arrangement that the piston rod is secured to a divided ring through a tapered ring by clamping a clamp nut.  
     CONSTITUTION: An end portion of a piston rod 1 is inserted into the hole 2b of a crosshead 2, and their end surface are joined to each other. Thereafter, a tapered ring 8 is moved in the direction of arrow a by clamping a clamp nut 4, whereby its tapered surface 9 is urged against the tapered surface 7 of the divided ring 5 and rendered into close contact therewith. The clamping force acting upon the clamp nut 4 is transmitted to the divided ring 5 through the tapered ring 8. Thus, a component of force in the direction of arrow b is produced in the divided ring 5, so that the divided nut 5 is forcibly secured to the piston rod 1.

Title: Surveying device utilizing electric wave and sound wave
Inventor: FUKUSHIMA MADOKA
IPC: G01K11/22
Filed: 1979-01-23
Abstract: PURPOSE: To improve the efficiency and accuracy of coherent addition of reflected electric waves and miniaturize an antenna in a surveying device, by designing the device such that a beam of sound waves and transmitting and receiving beams of electric waves are aligned with each other.  
     CONSTITUTION: The sound waves radiated from a primary sound wave radiator 21 are reflected on a parabolic reflector 23 to advance in the upward direction. The electric waves radiated from a primary electric wave radiator 22, which utilizes a reflector-carrying dipole, are reflected on the reflector 23, on which both sound waves and electric waves are reflected, to advance in the upward direction. Thus, the center of a sound radiation beam and that of an electric wave radiation beam are substantially in agreement with each other. Accordingly, the relation between the propagation of sound waves and the reflection of electric waves is as shown in curves in the drawing. The incident angle θ 2  of electric waves with respect to the sound wave surface is 1/2 of that in a conventional device of this kind. Thus, the efficiency of coherent addition of reflected electric waves can be improved.

Title: Method for detecting pixel change point for image data
Inventor: MURAKAMI YASUMICHI
IPC: H04N1/411
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To execute coding and decoding processing quickly with a simple processing configuration by using exclusive OR between image data and data obtained by shifting the image data by one bit right for change point detection data. SOLUTION: Image data d1 being a bit image and mask data d2 obtained by shifting the image data d1 by one bit right are XORed to generate change point detection data d3. Then the change point detection data d3 are referenced to detect a bit location in which an arithmetic operation result is true '1' as a change point between a pixel and a black pixel of the image data d1. Since one line is started from a white level image without fail, in the case of conversion to run length data d4, number of bits from a bit detected as a change point till a bit just before a succeeding change point is sequentially counted.

Filed: 1988-01-14
Abstract: PURPOSE:To rapidly display a picture by extending data by a codec and transferring it to an image memory in a time division. CONSTITUTION:In order to display the left side of a first displayed transfer range 8, it is scrolled towards the direction of a second transfer range 9 to transfer a picture to a frame memory 4 from the image memory 3. In parallel therewith, the picture read from a disk device 1 in the time division is extended by the codec 2 to store the picture displayed in a second picture storing range 11 and is started to transfer to the memory 3. When the transfer range 8 comes to the boundary of a first picture storing range 7 by repeating the two types of the transfer operations in the time division, the picture of the storing range 11 is generally completely stored. Therefore, the picture can be entered to a third transfer range 10 without stopping the scroll.

Abstract: PURPOSE:To divide character matrix to two lines and enable them to be printed out by loading the scanning number per se and the scanning number of the lower line into a line buffer and printing control codes to the character codes to be divided and printed. CONSTITUTION:The scanning line number (n) of the 1st line in the 1st line buffer 1 is set in a scanning counter 5, and the scanning line number (m) of the 2nd line is added to a lower line register 6. A divided printing flag 7 is set at 1, and is added with character code printing control codes. Therefore, the output of an AND circuit 9 is 1, and a selector 13 selects the total of the values of the counter 5 and register 6 from an adder 12. When the scanning times of the buffer 1 reach (n), the counter 5 goes 0, and the scanning of the buffer 1 ends, then the scanning of the buffer 2 is started. At this time, scanning line number (m) is set in the counter 5, the register 6 is made 0, and the flag 7 is reset at 0. Hence, the output of the circuit 9 comes to 0, and the selector 13 selects the output of the counter 5. On completion of the (m)-th scanning, the scanning of the buffer 2 ends.

Title: System timing synchronizing system
Inventor: MIYAO FUMIO
IPC: H04B10/07
Filed: 1984-01-20
Abstract: PURPOSE:To simplify an arithmetic device for executing the arithmetic at each station for the purpose of synchronism by setting a flag only to the packet of a station having leadership, and allowing each station to establish the system timing based on the distance from an optical star coupler. CONSTITUTION:A packet signal formed by a transmission logical circuit 11 is transmitted to optical cables 31a-31d and received by each station. When the transmission of the initial packet signal is succeeded, its station acquires a position as the master station and a flag is set to the packet transmitted from the station to establish the reference of frame synchronism. When stations other than the master station detect that the master flag is set, it is transferred to a timing set circuit 24. The set circuit 24 operates a distance code of the own station and a guard time of a packet signal at a position of the optical star coupler 30 to synchronize the system timing.
