Filed: 1980-04-26
Abstract: PURPOSE:To obtain stable images over a long term by forming many recesses and small holes on the surface of a developer support and embedding a substance increasing the triboelectric charging quantity of a developer in the recesses, etc. CONSTITUTION:To increase the triboelectric charging quantity of a one-component developer to a proper value, a charge controller is added to the developer, yet when the controller is used over a long term, developer support 9 is coated. As a result, the charging quantity is not increased to the proper value to cause a reduction in the image density.

When copy is repeated 30,000 times using the resulting sleeve, no reduction in the image density is caused since the nylon 66 increases the charging quantity to the proper value. Thus, stable images are obtd. over a long term.

Title: Optical disk apparatus
Inventor: TACHIBANA TADASHI
IPC: G11B21/02
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk apparatus which can increase a moving speed of a pickup thereby shortening an access time without affecting servo control. SOLUTION: Pulse waves (oscillation signal) of a higher frequency than a rotational frequency of a disk motor 14 (disk 12) are output from a pulse generator 30. The pulse waves are superposed selectively via a switch 34 to a driving voltage applied to a thread motor 24 (thread driver 26). As a result, the thread motor 24 is oscillated so much as not to move a pickup 16. A coefficient of static friction of gears between the thread motor 24 and pickup 16 is reduced, so that the pickup 16 can be tracked with improved efficiency. A gear ratio between the thread motor and pickup can be set low, and therefore the speed of the pickup is improved. Moreover, the pulse waves (oscillation signal) from the pulse generator never affect servo control.

IPC: H04N1/417
Filed: 1990-03-09
Abstract: PURPOSE: To increase the reproducing processing speed by using a reversible difference operator to generate an additional data set. CONSTITUTION: A microprocessor 1 applies the reversible difference operator to data of each dimension from the first position of each dimension to generate encoded data of an N-dimension array. With respect to at least one dimension, the reversible difference operator is applied to encoded data from a second position different from the corresponding first position to generate an additional data set which can reproduce the original data value of this dimension. Since the reversible difference operator is used and at least, one additional data set is generated in this manner, reproducing of the whole or a part of the original data value can be started from one or more positions in encoded data.  Therefore, the reproducing processing speed is increased and the storage capacity is reduced because it is unnecessary to reproduce the whole of a picture at the time of reproducing a part of the picture.
