Title: Control of discharge quantity of liquid feeding pump in liquid chromatography
Inventor: NISHIMURA KENICHI
IPC: F04B49/06
Filed: 1986-09-29
Abstract: PURPOSE:To keep the discharge quantity always constant independently of the regional difference of cycle by controlling the number of revolution per time by an ac motor by utilizing a photocoupler and timer, in a liquid feeding pump which necessitates the discharge quantity having the correct shift phases. CONSTITUTION:The signal of a photocoupler 1 is outputted from the slit 3 on a shielding plate 4 installed onto the driving shaft 2 of a motor, and the revolution of the motor is suspended by the signal. Intermittent operation is carried out by starting the motor again by a starting timer set at a prescribed time. In the use in the 50Hz region, the motor is continuously operated without exeucting the intermittent operation. In the use in the 60Hz region, the motor is stopped by the photocoupler signal, and restarted after a prescribed time, and the motor is continuously driven. Therefore, independently of the regional difference of cycle, the discharge quantity of a liquid feeding pump can be kept always constant.

Title: X-ray goniometer
Inventor: HORI AKIO
IPC: G01N23/00
Filed: 1984-10-31
Abstract: PURPOSE:To obtain a goniometer having high accuracy without using a mechanism having high accuracy by driving a fine adjusting mechanism for correcting errors by a piezo-electric element. CONSTITUTION:A detector holding arm 7 of the goniometer is mechanismically connected to a theta driving shaft so that the arm rotates by as much as twice the rotating angle of the theta driving shaft. The lower part of a sample holder 2 is a circular cylindrical part 2a coaxial with the theta driving shaft 1 and is fitted to a cylindrical sleeve 4 in a tight slide fitting state. The holder 2 is made rotatable within the range of the elastic torsion of a leaf spring 3. A base 5 is formed to the sleeve 4 and the rear end of the piezo-electric element 6 having the expanding and contracting direction in the direction tangential to the outside surface of the part 2a in fixed and rear end thereof is kept always in slight contact with the attaching step surface 16 of the spring 3 of the sample holder. The piezo-electric element expands and presses further the one side of the spring 3 when a voltage is impressed thereto. The spring 3 is therefore twisted by receiving the torsional torque by which the holder 2 is rotated at a slight angle with the shaft 1 to correct the error of the rotating angle of the shaft 1.

IPC: G03G21/10
Filed: 1986-09-30
Abstract: PURPOSE:To decrease the adhesive power of a residual developer to an image carrier and to permit easy recovery of the developer in a developing stage by charging electric charge on the image carrier by an electric charging means while moving the developer remaining on the image carrier from the image carrier by a moving means. CONSTITUTION:Both a photosensitive body 2 and residual coloring powder 26B are simultaneously electrically charged to the same polarity and, therefore, said body and powder repel from each other, upon passage through the charging stage, but not to the extent that the powder 26B is detached from the body 2. An electric field heading toward a magnetic developing brush from the body 2 is generated in the high charge part in the unexposed part of the electrostatic latent image when said body arrives at the developing stage. Insulating wires 24 are disposed in pressurized contact with the body 2 between a charger 6 for electric charging and the body 2 so that the surface of the body 2 is charged while the residual coloring powder sticking to the body 2 is moved by the wires 24. The adhesive power between the powder 26B and the body 2 is thereby decreased and the efficiency of cleaning the powder 26B on the body 2 by a developing device 5 in the developing stage is thereby improved.
