Title: Image forming device
Inventor: HANADA SHINJI
IPC: G03G15/08
Filed: 1985-06-04
Abstract: PURPOSE:To prevent toner from sticking to a no-image area by controlling the DC component of the developing bias of the no-image area so that the DC component is larger in absolute value than a development start voltage when a positive image is formed and smaller in absolute value than the development start voltage when a negative image is formed. CONSTITUTION:A switch S1 is changed over to a contact (e) in the no-image area and a switch S2 is changed over to a contact (f) during positive image information to apply the specific developing bias 16. No-image areas (h) and (k) are areas where parimary electrostatic charging is not performed and held at about 0V and while no-image areas (i) and (j) are held at a photosensitive body potential of -200V by exposure for charge erasure, a DC voltage of -350V is applied as the developing bias to the no-image areas (i) and (j). The potential contrast between the no-image areas of a photosensitive body and the developing bias is -150V and reversal neither normal development nor reverse fogging occurs. Consequently, much toner is prevented from sticking to no-image areas of the photosensitive body and no waste of toner consumption and no contamination in the device are caused, so that excellent images are obtained.

Filed: 1983-06-30
Abstract: PURPOSE:To obtain a high-sensitivity cell by constituting a cell body with materials whose acoustic impedance is approximaterly equal to acoustic impedances of a stored solution and a piezoelectric film and adding an electric signal taking- out lead wire to the piezoelectric film. CONSTITUTION:A piezoelectric film 4 is attached to cover the outside circumference of glass or quartz glass of a cell body 1, and they are brought closely into contact with each other by an epoxy adhesive, a silicone grease, or the like for the purpose of preventing a considerable attenuation of pressure waves due to penetration of air between the outside circumferential face and the film 4. Both faces of the piezoelectric film 4 are electrodes, and lead wires 7 are added, and one is earthed, and the other is connected to an amplifier. A sample solution is introduced into a storage part 8 from a leading-in part 2 and is filled up there, and light from a light source is irradiated into the storage part 8 through a transmission member 3 in the direction of a arrow X, and acoustic waves are generated in the sample solution, and a pressure is sensed through the cell body 1 by the piezoelectric film 4 to generate p potential. This potential is measured through the amplifier.

Title: Magazine replacing device
Inventor: SUZUKI HISAYA
IPC: B65G47/91
Filed: 1987-05-19
Abstract: PURPOSE:To transfer magazines of various sizes reliably and stably by providing a magazine holding/transferring device for transferring a magazine between a magazine mounting section and a magazine lifting/lowering section. CONSTITUTION:When a cylinder 29 in a magazine holding/transferring device 16 operates, a magazine holding section 28 advances toward the moving end of a magazine feed table and sucks a magazine 6, then the holding section 28 retreats to the moving end of a magazine lifting/lowering section so as to transfer the magazine 6 onto a lifting/lowering section 14. Consequently, the magazine 6 is transferred between a magazine feed table 12, a magazine discharge table 13 and the magazine lifting/lowering section 14 while being held on the magazine holding section 28 of the magazine holding/transferring device 16. As a result, even a narrow magazine 6 and a low height magazine 6 can be transferred stably without tilting at border abutting portions between the magazine feed table 12, the magazine discharge table 13 and the magazine lifting/lowering section 14.

Title: Descent height setting device of electric blind
Inventor: MINAMI KATSUJI
IPC: H02P3/06
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To specify and release a descent position of an electric blind easily by rotating a motor by a descent command, lowering the blind by winding a stringlike member back, and setting descent height by a dip switch based on a counted value. SOLUTION: Descent position height of an electric blind is set in ascent and descent commands of a controller 2. Moreover, it is possible to set descent position height of the blind at ascent and descent positions of the controller 2 which is away from a head box 15. Furthermore, the setting of its descent position height is done very easily and securely due to the simultaneous operation such as ascent and stop of descent. Consequently, it is possible to facilitate the adjustment of descent height of the blind even after the electric blind is installed on a window frame. Furthermore, easy change of descent height becomes possible even after descent position height is set.  Consequently, it is possible to improve the workability at the time of construction and assembly of the blind, omit a lower limit switch and reduce a combination of the lower limit switches, and control the blind accurately by a microcomputer.
