Title: Data processing system
Inventor: KASHIDA MOTOICHI
IPC: G06F3/05
Filed: 1988-07-15
Abstract: PURPOSE:To simplify hardware constitution without improving the processing speed of a CPU by executing the reading of a reproduced time code and the control of data output timing with the same CPU. CONSTITUTION:A buffer memory 61 controls the output timing of the parallel data of 16 bits to a terminal 62 in order to compensate a part, in which the time mismatching of reproduced data from two types of decode data can not be mechanically compensated. The timing control of writing and reading in the memory 61 is executed by supplying the reproduced time code to a host computer with a CPU64 and receiving the command of output time control. Further, the CPU64 executes the giving and receiving of the data with a clock generator 56 for the formation of the time code. However, since the CPU64 executes processing at a low speed in comparison with a CPU for the correlative arithmetic of a correlation device, the high speed processing is not requested. Accordingly, since the exclusive CPU is not provided, a data processing system is simplified even in the hardware constitution.

IPC: B23K26/08
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To maintain a stable working accuracy and working quality even when a cutting plane of a pipe is inclined. SOLUTION: When cutting a pipe on condition that a laser beam machining head 7 equipped with a freely swingable nozzle 9 for emitting laser beam is moved and positioned on a processing plane of a pipe, e.g. in the direction of X, Z axes, the pipe is held by a holder attached to a pipe rotating device on a working table and then two coordinates of point P1 and point P2 on the processing plane of the pipe are measured by a profiling detector 23 at a fore end of the nozzle. By measured coodinates (X0, Z0) and (X1, Z1) of the points P1 and P2, inclined angle θ of the pipe is automatically calculated. According to that the nozzle 9 is inclined by the same inclination angle θ, the fore end of the nozzle is set perpendicular to the processing plane of the pipe.  On such condition, the pipe is rotated by a pipe rotating device and is cut, so faults in processed size due to inclination of the pipe and defective working do not occur, and working accuracy and working quality get stable.

Abstract: PROBLEM TO BE SOLVED: To attain synchronized output of both voice and image data by adding synchronization information through time control to the voice and image data so as to generate synchronized data as intended by the sender and allowing a receiver side to reproduce the data with the synchronization information. SOLUTION: The receiver side stores received voice data and image data to a voice storage section 104 and an image storage section 106, an integral processing section 107 extracts synchronization information and a time control section 1-9 controls outputs of voice or image data based on its output time. Thus, the voice and image data with the synchronization information are stored in each storage section and the synchronization data are reproduced. Furthermore, voice and image data are entered by a voice entry section 112 and an image entry section in the transmitter side and a synchronization information input section 116 enters the synchronization information and a synchronization information addition section 115 adds the synchronization information using time information.  Thus, a sender sends the data with the synchronization information so as to synchronize the voice and image data as intended.

CONSTITUTION:During the compression stroke in which a piston 2 moves toward a lower operating oil room B, the operating oil in the lower operating oil room B pushes a back valve 5 open from the compression side port 2a of the piston 2 irrespective of vibrational frequency and flows into an upper operating oil room A. Also the oil pushes a check valve 6 open from the through hole 4f of a piston nut 4 and passes through a compression side variable orifice 15d and flows into the upper operating oil room A while pushing a check valve 24 open through a check port from an inner passage 15f. Simultaneously, the oil flows into a reservoir room through a base valve. A compression-side damping force is generated by the combined action of the back valve 5 and the compression side variable orifice 15d and by the base valve.

Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce the production of NOx in the ignition stage of coal dust by a method wherein an average ratio, consisting of the rate of oxygen in primary gas and a necessary amount of oxygen for burning combustible volatile constituents, is reduced. SOLUTION: A ratio, based on the rate of oxygen in primary gas and the necessary amount of oxygen for burning voltage constituents in the primary gas, is reduced. For this purpose, a swirler 24 is arranged at the vicinity of entrance of a burner in a dust pipeline 7 while the swirler 24 divides the flow of mixture, consisting of the primary air and coal dust, into a dust-rich branch flow at the outside and a dust-poor branch flow at the inside of the pipeline 7. Thereafter, the dust-poor branch flow is received from the divided flow of mixture through a predetermined pipeline constitution and is supplied into a primary gas pipe 9. On the other hand, the dust-rich branch flow or the branch flow including little air arrives at a primary dust pipe 6.  Thus, these branch flows are supplied into the ignition area of the burner through mutually separated passages under different loads of dust.
