Title: Method for modifying activated carbon
Inventor: MIKAMI HIDETO
IPC: B01J20/20
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To suppress the release of a chemical substance from activated carbon and the generation of dust, to remarkably improve the ability of the carbon to adsorb chemical substances, especially volatile org. compds. and to remarkably increase the amt. of chemical substances adsorbed by impregnating an aq. sodium silicate soln. into the activated carbon and coating the pores in the carbon with a thin glassy film. SOLUTION: Activated carbon is added to an aq. sodium silicate soln. enough for impregnation and they are mixed under mild stirring so that the powdering of the carbon is not caused. In order to accelerate the penetration of the sodium silicate soln. into the pores in the carbon, a vessel contg. the resultant mixture is evacuated and the internal pressure is suddenly raised preferably to atmospheric pressure by introducing gas into the vessel. The sodium silicate soln. is forced to enter the pores in the activated carbon and satisfactory impregnation is carried out in a relatively short time. The activated carbon is then taken out, freed of the soln. and dried preferably under heating. The surface of the activated carbon and the surfaces of the pores in the carbon are coated with a thin glassy sodium silicate film.

Title: Positioning device
Inventor: SHIRAKI SHINJI
IPC: G05B19/404
Filed: 1994-10-31
Abstract: PURPOSE: To correct the position shift of a motor that is caused by the offset voltage generated by a control system. CONSTITUTION: When the position command Pd outputted from a position command production circuit 3 is not equal to the final one, a decision circuit 14 outputs '0' to a correction value production circuit 15. At the same time, the preceding correction voltage V stored in the circuit 15 is used as it is and outputted to an adding point D. If the information showing that the command Pd received by a deviation calculation circuit 11 is the final one is received, the circuit 14 receives the deviation (e) from the circuit 11 and outputs it to the circuit 15. The circuit 15 multiplies the deviation (e) by a transmission function 1/Ts and adds this multiplication value (e/Ts) to the voltage V which is used this time. Then this addition value (e/Ts+V) is outputted to the point D as the new correction value V.

Title: Recording part cleaning device of ink jet recorder
Inventor: NISHIYAMA RITSU
IPC: B41J2/20
Filed: 1986-11-12
Abstract: PURPOSE:To improve cleaning capacity and thereby obtain a cleaning device capable of drying in a short time by introducing ultrasonic cleaning and permitting alternate selection of washing solutions in such an order as flon solvent, water and flon solvent. CONSTITUTION:Flon solvent is introduced into a washing vessel 2 from a washing solution container 5 by means of a circulation device 4. This introduction process continues until it overflows into a washing bath inside an ultrasonic cleaner 1 and accumulates there. Then a recording part 3 is cleaned by means of ultrasonic waves in the washing bath by the ultrasonic cleaner 1. This cleaning enables separation and floatation above the liquid level of dust or ink in the minute corners of the record ing part 3. The ink afloat overflows into the washing bath of he ultrasonic cleaner 1 by the circulation device 4 together with a flon solvent. The overflowing liquid is recovered into another container to minimize the contamination of the liquid in the container 5. Next, water in a washing solution container 6 is introduced into the washing bath and washing vessel 2 by the same process to perform ultrasonic cleaning in a circulation state. Finally flon solvent in a washing solution container 7 performs ultrasonic cleaning in the same steps, removing the residual water. The flon solvent remaining in the recording part 3 evaporates spontaneously in the air or is forcibly dried by a blower provided in the cleaning device.

Title: Converging type solar battery element
Inventor: TANGE KYOICHI
IPC: H01L31/0236
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a solar battery element which can restrain carrier recombination and flow-in of carrier to a bank part and can improve photoelectric conversion efficiency. SOLUTION: A p<+> -diffusion layer 16 is formed in a surface of photosensitive part 10 formed on a silicon board 12 constituted of p-type silicon. Since an energy gradient is generated between the p<+> -diffusion layer 16 and the silicon board 12, it is possible to prevent free electron which is minority carrier of carriers generated in the silicon board 12 as the photosensitive part 10 is irradiated with solar light from moving to a surface side and prevent recombination of free electron due to the lattice defect of a surface. Furthermore, the p<+> - diffusion layer 16 is also formed in a rear side of a bank part 14 in a circumference of the photosensitive part 10 and free electrons of minority carrier is prevented from flowing in, owing to function of the energy gradient. As a result, photoelectric conversion efficiency can be improved.
