Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To obtain an adaptive filter device and a signal processing method for realizing a highly precise movement adaptive processing by suppressing the increase of a circuit scale. SOLUTION: An adaptive filter device 10 writes supplied data in a memory part 14 under the control of a memory control part 16, and reads the data under the reading control of the memory control part 16 so that the reading start position DS of the data is shifted at each number of 4 taps and a data block DB divided at each number of 8 taps of an FIR filter part 12 is delayed. The reading speed is set two times as fast as the writing speed, and data corresponding to each delay element circuit 12b-12h of a delay circuit 12 are provided to each delay stage of a tap part 12B. Also, reading under the consideration of movement detection amounts (for example, vectors or the like) is operated in the memory part 14.  The memory control part 16 controls the output of a multiplication coefficient from a multiplication coefficient outputting part 18 to the tap part 12B so that only the number of coefficients corresponding to the number of 4 taps can be outputted, and the arithmetic results are totaled by an adder 20 and outputted.

Title: Rotational driving mechanism
Inventor: AKITAKE HIROSHI
IPC: G03B9/08
Filed: 1987-10-15
Abstract: PURPOSE:To prevent a sequence from generating a time loss by selectively driving two loads coupled with a differential gear mechanism and allowing one load to drive in both directions. CONSTITUTION:When an AE gear 30 is locked by a driving pin 9 and disabled to form rotating, rotation of an inner gear 24 with light load in the differential gear mechanism 20 is interrupted, a planetary gear 23 is revoluted and a carrier 22 is rotated. The rotation of the carrier 22 with heavy load is transmitted to an AF gear 35 and focusing operation is executed. At the time of transferring operation to the focusing operation, a motor 5 is enabled to rotate in both the forward and reverse directions. If the rotation of the inner gear 24 is interrupted when the motor 5 is forward rotated, the carrier 22 is practically rotated in an arrow (b) direction. When the motor 5 is reversely rotated as shown by a dashed line, the carrier 22 is rotated in a dashed arrow (c) direction. After stopping the rotation of the inner gear 24, the driving torque of the motor 5 in both the directions is transmitted to the AF gear through the carrier 22, so that the motor can be optionally rotated in both the forward and reverse directions.

Filed: 1986-10-30
Abstract: PURPOSE:To perform a laser beam machining without having the adverse effect due to the plasma generation by scanning a laser beam by reducing the output of a laser machining part, removing the plasma generating substance on the surface with its burning and scanning it by increasing the output by the same laser beam. CONSTITUTION:A laser beam head 4 is set at the upper part of the weld zone 3 where the respective end part 1a, 2a of zinc plated steel plates, 1, 2 are overlapped and the scanning by a layer light of lower output than an ordinary laser beam machining time is performed. In this stage the zinc plating on the surface of the zinc plated steel plate 1 is removed with its burning and the plating removed part 3' exposing the steel plate of the base metal is formed on the weld zone 3. The scanning by the laser light of higher output than that at the pre-machining stage is performed by the same laser beam head 4 for the plating removed part 3' formed by the pre-machining treatment. The plasma generation by the laser light projection is thus restrained remarkably and a sure and good welding is obtd.

Title: Image blur correcting device for camera
Inventor: TERAMOTO TOGO
IPC: G03B5/00
Filed: 1989-10-04
Abstract: PURPOSE:To highten a correctable image blur speed by actuating a stepping motor in its actuating area before a shutter opens, and followingly operating it so that its pulse speed can be accelated to that required for correcting the image blur immediately before the shutter opens. CONSTITUTION:The stepping motor 2 is driven a prescribed time before the shutter opens, and an image blur correcting pulse is generated by a pulse generating circuit 31. When a judgeing circuit 32 judges that the pulse speed fp of the image blur correcting pulse exists in a through area, a slow-up pulse is outputted from a slow-up circuit 33. Moreover, when the slow-up circuit 33 is in operation, a compareing circuit 34 compares the pulse speed fp of the image blur correcting pulse with the pulse speed fSL of the slow-up pulse. If fP> fSL, the slow-up pulse is outputted, whereas if fp<= fSL, the image blur correcting pulse is outputted. Thus, the correctable image blur speed can be hightened immediately after the shutter opens.

Title: Position information discriminating device of position controlling system and its method of distinguishment
Inventor: KOU SANEI
IPC: G05B19/19
Filed: 1993-10-19
Abstract: PURPOSE: To reduce the production cost of the positional information discrimination device through its simplified and software constitution by comparing the current positional information on a motor obtained by a position counter with the normal position instruction value. CONSTITUTION: A position counter 60 counts in every fixed cycle the current positional information on a motor 50 that is detected with a position detector 40 and sends this information to a CPU 10. The CPU 10 reads the received information to obtain the position information data and compares this data with the normal position instruction value stored in the CPU 10 itself. Then the CPU 10 outputs the position control value of the motor 50 that corrected the difference between the preceding positional information data and position instruction value to a D/A converter 20. The converter 20 converts the position control value into the analog data to control the motor 50. As a result, the system constitution part is minimized and simplified and then the system production cost is reduced through a software structure of the system together with improvement of the system accuracy.  Therefore, both productibity and workability can be improved on a production line. In other words, the current positional data on the motor 50 can be accurately counted and the system can be accurately controlled in its minimum constitution.

Inventor: TAMURA SHUICHI
IPC: B23Q3/00
Filed: 1984-12-10
Abstract: PURPOSE:To prevent the abnormal abrasion and leak of oil and reduce the dimension of the apparatus by laying a chain onto a sprocket at the top edge of a cylinder rod and turning the sprocket through the elongation and contraction of the rod by a case-side rack and transferring a clamp at the top edge of the chain. CONSTITUTION:When a working cylinder 23 is extended from contraction state to extension state, a sprocket 19 is raised, and a chain basic edge part 13 lowers. Then, a top edge side longitudinally long chain 21 is raised, and a clamp 51 connected to the chain top edge part 12 is pulled rightward. When the working cylinder 23 is contraction-driven reversely, the sprocket 19 is lowered and the chain basic edge part 13 rises. Therefore, the sprocket 19 is turned rightwardly by the engagement with the basic edge side longitudinally long chain part 20, and the top edge side longitudinally long chain part 21 is pushed- down to push-out the clamp 51 leftward. Since a hydraulic motor is not used, the abnormal abrasion due to acceleration speed is eliminated, and leak of pressurized oil is prevented, and the useless consumption of pressurized oil can be prevented, and a simple apparatus having a low height can be obtained.

IPC: G03G21/18
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent a streaked stripe caused on an image because a contaminant adhering to the electrification surface of an electrifying member absorbs moisture and resistance becomes low, so that it becomes the nucleus of abnormal discharge. SOLUTION: A resistance layer 24 is provided on the surface of a conductive heating electrifying plate 23 and arranged proximately to the surface of a photoreceptive drum 1.

By impressing the voltage, magnetic flux interlinked is formed on the plate 23 and in turn an induced current is generated in the plate 23 by the magnetic flux, and further Joule heat is generated. The moisture of the electrification surface is removed by the Joule heat.
