Title: Constant pressure grinding method
Inventor: ITO TOSHIHARU
IPC: B24B47/10
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent a lowering of grinding efficiency due to clogging, to dispense with frequent resetting, to lengthen the life of a grinding wheel and to simplify a grinding process by fluctuating the number of revolution of the grinding wheel in chaos. SOLUTION: A computer 21 is incorporated into a control panel and the control panel controls the number of revolution of an AC servo motor 8 rotating and driving a grinding wheel. A secular target number of revolution outputted from the computer 21 is determined as a number of revolution proportional to a time series Z solution between a maximum value and a minimum value by solving a Lorentz equation and obtaining the time series Z solution showing a chaos behavior. The number of revolution is reproduced at the same time as the starting of an operation of a grinding device and is outputted to a servo amplifier 23. The servo amplifier 23 controls the number of revolution of the AC servo motor 8 to follow up the target number of revolution, referring to a feedback signal from an encoder incorporated into the AC servo motor 8.  As a result, grinding efficiency becomes efficient and clogging of the grinding wheel is effectively prevented.

Title: Toner for developing electrostatic latent image
Inventor: YASUNO MASAHIRO
IPC: G03G9/08
Filed: 1990-11-13
Abstract: PURPOSE:To make improvements in developability and image density as well as to make it have sufficient transferability by providing a nonisolable fine grain locally on an isolative toner grain surface, and letting a toner grain act as its isolability in a static manner. CONSTITUTION:A nonisolable fine grain stuck fast to an isolative toner grain surface is locally provided on a toner surface, and this toner grain acts as its isolability in a static manner. This nonisolable fine rain receives an electric load from a latent image, and this part shows an electric potential approximating to the latent image after the toner grain is stuck onto the latent image, whereby a new toner grain is further stuck onto the toner grain, therefore plural layers of toners are stuck onto the latent image, thereby making image density improvable in consequence. On the other hand, at time of transfer, the nonisolable fine grain stuck onto the toner surface is merely provided locally and discontinuous, so that at time of electrostatic transferring, such a fear that the electric charge will run past on the toner surface is not caused, thus good transferability is secured. With this constitution, sufficient image density is securable and simultaneously both of good developability and transferability are securable too.

Title: Measuring method for coercive force of magnetic medium
Inventor: ISHIMORI HIDEO
IPC: G11B5/84
Filed: 1989-11-22
Abstract: PURPOSE:To shorten the measuring time of coercive force by shortening one cycle of an alternating magnetic field by performing the sweeping of an exciting current slowly with respect to a range large in the change of a degree of magnetization while performing the same at high speed with respect to a range other than said range. CONSTITUTION:An alternating magnetic field is swept from the point st of the min. value Hmin of magnetic field intensity to the point sp of the max. value Hmax. thereof with respect to a magnetic medium and, next, when the alternating magnetic field is swept in the opposite direction to measure one cycle of the alternating magnetic field, a loop curve of magnetic field intensity H : magnetization degree K is obtained as shown by a drawing (a) and, at this time, coercive force is suddenly changed in the vicinity of points (q), (r) where the magnetization degree K becomes zero. Then, the sweeping of an exciting current I within a range of points (a) - (d) centering around the points (q), (r) is made slow to prolong the time while the current is swept at high speed within a range other than said range to shorten the time. Whereupon, the waveform of the current I is deformed as shown by a drawing (b). By this method, sampling of a short time interval becomes possible in the vicinity of coercive force to enhance measuring accuracy and, since the exciting current is swept at high speed within the range other than the range of the points (a) - (d), one cycle time is shortened as a whole. Therefore, many measurements become possible.

Title: Concentration detector for developer
Inventor: KUBOTA YOICHI
IPC: G03G15/08
Filed: 1987-12-01
Abstract: PURPOSE:To simplify mechanism and to exactly detect the concen. of a developer without receiving the influence of a temp. rise by monitoring the detection voltage obtd. from a light receiving part for detecting reference light and feeding the same back to a bidirectional light emitting part. CONSTITUTION:A transparent window 34 and a light receiving element 31 are provided on one side of a light emitting element 30. A light receiving element 32 as the light receiving part for detecting the reference light is provided on the other side. The concn. of the developer D is detected by the diffused and reflected light from above a developing sleeve 14. The voltage of the light receiving element 32 for detecting the reference light which hardly receives external influence is monitored and fed back to the light emitting element 30. Namely, the specified detection voltage of the light receiving element 32 for the reference light is maintained at all times constant by decreasing the current flowing in the light emitting element 30 when the output voltages of the light receiving elements 31, 32 increase with an increase in the temp. The mechanism is thereby simplified and the concn. of the developer is always detected exactly without receiving the fluctuations in the characteristics of the light receiving and emitting parts by the change with time and environment.

IPC: B29L7/00
Filed: 1987-11-30
Abstract: PURPOSE:To make exchange of heating units unnecessary even if a length of a stuck side of a polyester film varies by a method wherein a heating unit of a necessary length whose heating surface has been formed on a fixed slope is moved in parallel with the stuck side along the same within a very short distance of the same while taking contraction of the stuck side of the film piece into consideration. CONSTITUTION:A film piece A obtained by superposing two sheets of the films upon each other, a stuck side (a) of which is pinched, pressed and supported between a pinching, pressing and supporting plate 1 and pinching, pressing and supporting rest 2 so that the stuck side (a) is ejected out of a pinching, pressing and supporting device 3 by a necessary width and a moving stage 7 in a heating device 5 is moved in parallel with the film piece A from the right side to the left side at a fixed speed. Therefore, the heating unit 4 is moved along the stuck side (a), the stuck side (a) is heated continuously in lengths of the heating unit 4 each and the whole length of the same is heated. When the stuck side (a) is heated, contraction is generated through melting at a certain place corresponding to the length of the heating unit 4 in the stuck side (a) and the contraction is kept becoming larger according as the heating unit 4 moves a distance corresponding to its length. As a space of a heating face 4a to the stuck side (a) becomes gradually smaller extending from a tip part to a rear end part is kept superposing upon the stuck side (a) from appearance point of view at the rear end part, in the heating face 4a of the heating unit 4.
