Abstract: PURPOSE: To prevent a yarn from being damaged by friction when winding is started around a vacant bobbin with a friction roller, related to a method and apparatus for winding a yarn. CONSTITUTION: When a winding is started with a bobbin winder with a gap S provided between a contact roller 19 and bobbin case 11, a controller which controls the speed of a peg 9 bearing the bobbin case 11 is instantly switched by utilizing the disturbance in speed which is caused by contact of a bobbin package on the bobbin case 11 to the contact roller 19.

Title: Acceleration responding element and acceleration sensor
Inventor: URANO MITSUHIRO
IPC: G01C9/06
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a small-size acceleration responding element outputting a sufficiently large output signal, allowing an easy distinction process between earthquake vibration and living vibration. SOLUTION: This acceleration responding element 1 has a nearly cylindrical sealed vessel 2 that is a main electrode, and plural sub electrodes 5A, 5B disposed at even intervals. An electroconductive liquid 4 is enclosed in the sealed vessel 2 by a proper amount. When a slant angle of the sealed vessel 2 changes, a contact amount between the sub electrodes 5A, 5B and the electroconductive liquid 4 changes to cause a change in a resistance between the main electrode 2 and the sub electrodes 5A, 5B. By setting an inner diameter of the sealed vessel 2 to 4-25 mm, a resonance frequency can become higher than a frequency of an earthquake wave.  By disposing the respective electrodes 5A, 5B at intervals above at least 1 mm from each other within a moving range of a liquid surface 4A, influence of viscosity of the electroconductive liquid 4 upon movement of the liquid 4 can be reduced to a negligible degree.

Title: Image forming device
Inventor: IZUMIZAKI MASAMI
IPC: G03G15/16
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent toner from adhering to an oil removing means by separating the oil removing means from a recording material carrier and allowing an auxiliary cleaning means to abut on the recording material carrier when the jamming of a recording material occurs. SOLUTION: In the case of detecting the jamming in the midst of forming an image, an oil removing roller is separated from a carrying belt 130 before stopping machine actions. After performing preparation for restart such as the removal of the jammed recording material, a cleaning blade 23 is allowed to abut on the carrying belt 130 so as to clean the carrying belt 130 with a cleaning web 19. Since the oil removing roller is separated from the belt 130 at this time, a situation that the toner adheres to the oil removing roller and oil removing ability is lowered is prevented. Furthermore, since much toner exists on the belt 130 at the time of cleaning the belt 130, releasing agent oil is removed from the belt 130 together with the toner.

Title: Variable gain amplifier
Inventor: DEGUCHI TAKUMI
IPC: H03G3/10
Filed: 1989-07-14
Abstract: PURPOSE:To suppress the fluctuation of an output operating point by connecting each collector of a 1st transistor(TR) pair for signal amplification and of a 2nd TR pair for current bypassing, and using a 4th TR pair to control a load current constant. CONSTITUTION:An input signal is amplified with a gain depending on load resistors 7, 8, emitter resistors 9, 10 and a DC current at TRs 1, 2. TRs 22, 23 are used to decrease the impedance when viewing from collectors of TRs 1-4 and do not give almost any effect onto the gain. Since the current flowing to the TRs 1, 2 varies with the potential difference at grain adjustment terminals 16, 17, the gain is also changed. Then the same current as the change in the DC current increased/decreased by the TRs 1, 2 is decreased or increased in the TRs 3, 4. In such a case, the load current flowing to the TRs 23, 24 is the sum of collector currents of the TRs 1, 3 and 2, 4 and the sum is constant. Then the operating point at output terminals 18, 19 is made constant.

Title: Multi-sheet copying electrophotographic method
Inventor: NISHIKAWA MASAHARU
IPC: G03G13/22
Filed: 1980-12-23
Abstract: PURPOSE:To prevent the deterioration of a latent image, by applying a process for activation using the full-surface exposure in case plural sheets of copy are obtained from the same latent image with use of a photoreceptor comprising a conductor layer, a visible light conductor layer plus a function layer different from those two layers mentioned above. CONSTITUTION:A visible light conductor layer 33 and a function layer 34 are laminated on a conductor layer 32 to form a photoconductor 31. The layer 34 consists of an insulated matter or an ultraviolet light conductor. The electric charge is trapped on both surface of the layer 33 or 34 to form an electrostatic latent image. Thus plural sheets of copied pictures are obtained from the above- mentioned latent image. Figure A shows the process of development in which a part of the charge of the latent image leaks out. Figure B shows the process of transcription in which the electric charge is injected to a non-picture part. In accordance with these processes, the electric charge is induced to the layer 32. Figure C shows the recovery process for the deterioration of the latent image under which the full-surface exposure is carried out with the visible light for instance. The induced electric charge disappears, and the effect of the electric field to the outside is increased.
