Title: Dewdrop preventive device for photosensitive body
Inventor: MORIKI ETSUZO
IPC: G03G21/00
Filed: 1986-09-18
Abstract: PURPOSE:To prevent vapor contained in an atmosphere from being condensed as dewdrops due to cooling on the surface of a photosensitive body, by heating the photosensitive body by a heating means, when the surface temperature of the photosensitive body is lower than an atmosphere temperature, and always keeping a state that the surface temperature of the photosensitive body is higher than the atmosphere temperature. CONSTITUTION:A temperature S2 detected by a photosensitive body temperature sensor 32 is lower than the actual temperature of the outside surface 12a of a photosensitive drum 12. A atmosphere temperature S1 is detected by an atmosphere temperature sensor 28, and a detecting signal corresponding to the temperature S1 and S2 is inputted to a comparator 52. When a difference between the temperature S2 and the temperature S1 becomes 1 deg.C, the output terminal of the comparator 52 becomes an on-state, the rectifying voltage of a charger 44 is applied to a heater 14 through a diode 48, and the photosensitive drum 12 is heated. As a result, the temperature S2 of the outside surface 12a of the photosensitive drum 12 is always kept higher than the atmosphere temperature S1. In such a manner, it does not occur that a dewdrop for exerting an adverse effect on the quality of a print is generated on the outside surface 12a of the photosensitive drum 12, in the course of operation.

Inventor: CHIBA TOMOO
IPC: B60M7/00
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To lower the generated electromagnetic force of a current collecting coil and restrain the vibration of an outer tank by mounting a current collecting coil at a position where electromagnetic force working on the ground coil side surface of the outer tank in the external direction becomes weak. SOLUTION: Four current collecting coils 311 to 314, 321 to 324, 331 to 334, 341 to 344 are mounted, respectively, at equal intervals for superconducting coils 11 to 14. If the disposing distance of the superconducting coils is L, a pitch (b) for disposing current collecting coils 30 is 1350 mm/4 = 337.5 mm. The pitch (b) becomes smaller than a pitch of 2/3 of the cycle of harmonic generated at the surface of an outer tank. With this constitution, a boundary between the current collecting coil is positioned near a boundary 26 between race track superconducting coils, and the perpendicular conductor of the current collecting coil 30 is not installed on the arc part of the superconducting coil where the outward electromagnetic force of the outer tank is maximum, thus it is possible to lower outward electromagnetic force working on the current collecting coil 30.

Title: Reproducing device
Inventor: YAMAGISHI YOICHI
IPC: H04N5/91
Filed: 1988-09-05
Abstract: PURPOSE:To prevent the occurrence of distortion in a reproducing processing even when a track recorded in a different recording method is reproduced in succession and to prevent the occurrence of deviation in the vertical synchronization of a picture and white stripes by selecting or controlling a level adjustment for an adjusting means according to a detecting result of a detecting means. CONSTITUTION:A switch 74 is connected to a contact (c) to select a DC voltage source 73 for mute by a system control circuit 10 to move a head 14 to a first track to be retrieved with a head driving circuit 60, and the switch 74 is connected to a contact (b) in the case of a low band or to a contact (a) in case of a high band by judging an output of a band discriminating circuit 66. Then, at the time of reproducing a low band recording track, an FM demodulation output is impressed as it is on a deemphasis circuits 22 and 28, and at the time of reproducing a high band recording track, the FM demodulation output is negated in its DC potential difference by a level shift circuit 72 to be impressed as well. By this method, irrespective of the recording form of a recording medium, fluctuations of the demodulation signal in its electric potential can be offset, thus preventing deviation in the vertical synchronization and white stripes from happening to the reproducing picture.
