Title: Electrophotographic device
Inventor: FUJII SHIGEHIRO
IPC: G03G21/06
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To accurately detect the capacity of a charge-removing equipment to removing charge, to prevent a trouble caused by a deterioration in the capacity to remove charge and to use the measured value of the potential of an electrostatic attracting belt after charge removing precessing, for the control of the operation of the charge removing equipment by measuring the potential. SOLUTION: A paper sheet 10 is electrified together with the electrostatic attracting belt 1, by an electrifying roller 4 and electrostatically attracted to the belt 1. Toner images of each color are transferred to the paper 10 by a transfer roller 54. After the toner images are fixed, an electric charge on the surface of the belt 1 separated from the paper 10 is removed by a charge removing brush 8, to uniformize the distribution of the charge. The potential of the belt 1 after charge removing processing is measured by a potential sensor 9, converted into digital data and then, inputted into a voltage control part 12.  Then, a voltage applied to the charge removing brush 8 is decided by the voltage control part 12, to make the potential of the belt 1 after charge removing processing a fixed one and the decided voltage data is converted into an analog signal, to be inputted to a high-voltage power source 14 and applied to the brush 8.

Title: Self-scanning type semiconductor laser
Inventor: ARIMOTO AKIRA
IPC: H01S5/00
Filed: 1985-12-23
Abstract: PURPOSE:To provide a semiconductor laser beam source itself with the functions of beam deflection and scanning by changing the oscillation direction of a laser to direct it toward and arbitrary direction by displacing the installed direction of a resonator. CONSTITUTION:On a ultrasonic crystal 11, electrodes for ultrasonic excitation are arranged in positions 131-13n and the symmetrical positions 131'-13n' regarding a laser amplification medium 12. For example, when ultrasonic waves are projected from a pair of electrodes 13k and 13k' toward the laser medium, interference fringes due to the two ultrasonic waves are produced on the laser medium 12 and a diffraction grating due to parallel interference fringes whose period is 1/2 the wavelength of the ultrasonic is formed. The direction of stripes of said diffraction grating is orthogonal to the line connecting the electrodes and a refractive index in the diffraction grating changes synchronously with its period. As laser oscillation is to be generated in the laser medium 12, the control of longitudinal mode is effected by the intervals of the diffraction grating which is formed also in the laser medium by leaking the ultrasonic waves excited in the ultrasonic crystal into the laser medium.

Title: Production of weakly acidic crystallized zirconia-based sol
Inventor: YOSHIKAWA MASATO
IPC: C01G25/02
Filed: 1988-11-16
Abstract: PURPOSE:To obtain the title sol which has never been obtained conventionally by heating an aqueous suspension containing zirconium hydroxide to give an aqueous mixture containing crystallized zirconia, adding an acid to the aqueous mixture, peptizing the mixture and dehydrating the zirconia sol. CONSTITUTION:An aqueous suspension containing zirconium hydroxide is heated and maintained at >=80 deg.C until zirconia is sufficiently crystallized to give an aqueous mixture containing crystallized zirconia. Then the aqueous mixture is blended with an acid and zirconia is peptized to give sol of fine crystallized zirconia dispersed in an aqueous solvent. Then the acid is removed from the sol. Removal of the acid is not especially restricted and, for example, removal of low-boiling acid by heating, adjustment of pH>=5.0 with anion exchange resin, etc., may be cited as the removal of acid. Consequently, weakly acidic crystallized zirconia-based sol having pH of weak acidity, excellent dispersibility and dispersion stability is obtained.

Title: Chip-type variable resistor and method of mounting the same
Inventor: HONMA TOSHIO
IPC: H01C10/32
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To stabilize electrical and mechanical characteristics by connecting terminals to electrodes using high-temperature soldering. SOLUTION: In this chip-type variable resistor, a cream solder 13 is coated on a conductive pattern on a printed wiring board 20, terminals 5 and 6 of the chip-type variable resistor are placed so as to be in contact with the cream solder 13. Low-temperature solder with lower melting point than the high- temperature solder (melting point of 220-330 deg.C) soldering the terminal 5 is used as the cream solder 13. In this state, the print wiring board 20 mounted with the chip-type variable resistor is passed through a reflowing furnace (at about 220 deg.C), and the chip variable resistor and the conductive pattern of the printed wiring board 20 are stably connected through soldering.  Gaps are formed between the lower surface of the insulating substrate 1 and the lower surface of the bottom plate 5a of the terminal 5, and between the lower surface of the insulating substrate 1 and the lower surface of the terminal 6, respectively, thereby surely causing flux and solvent of the cream solder 13 to scatter.
