Title: Electric dust collector
Inventor: MATSUMOTO YOUICHI
IPC: B03C3/36
Filed: 1983-08-03
Abstract: PURPOSE:To enhance dust collecting capacity to ultra-high resistance dust easy to generate inverse ionization or high resistance dust easy to generate a low current spark to a large extent, by providing a preparatory charging apparatus comprising an opposed electrode having distributing action and a discharge electrode. CONSTITUTION:When high negative voltage is applied between discharge electrodes 1 and distribution plates 2 by a pulse power source 5, a continuous or pulse like negative ion current flows toward the earthed distribution plates 2 from the discharge electrodes 1. In this case, because applied voltage is a high voltage pulse, spark voltage rises to a large extent and an extremely high electric field is also formed. Particles in exhaust gas guided into the inlet enlarged pipe part 6 of a dust collecting apparatus are charged up to the vicinity of the theoretical charge amount thereof within a short time by a high electric field and an ionic current formed between the discharge electrodes 1 and the distribution plates 2 (one stage or several stages) and flowed to the dust collecting part of the electric dust collecting apparatus in the downstream side.

Title: Color image forming apparatus
Inventor: KASAHARA NOBUO
IPC: H04N1/23
Filed: 1992-06-03
Abstract: PURPOSE:To increase a monochromatic image forming speed and reduce the energy loss by making an image forming process speed at the time of the formation of a monochromatic image higher than that at the time of the formation of a full-color image and increasing the scanning speed of laser beam. CONSTITUTION:A signal indicating either one of full-color, white and black and monochromatic copy modes is outputted by an operation part selection switch 13 and received by a scanning speed changeover means 12. This changeover means 12 sets the rotational speed corresponding to an indicated mode to a motor driver 17 through a DC controller 11. That is, a scanner motor 1 is controlled so that an image forming process speed becomes a desired speed and the rationalization of an image forming process condition such as developing bias is performed through a developing bias power supply 20 and a high voltage power supply 21. In the case of the white and black or monochromatic mode, the number of rotations of a rotary polygonal mirror 3 is set high. That is, the scanning speed of laser beam 8 is changed over to a higher speed.

Title: Dry control system for grain dryer
Inventor: NISHINO EIJI
IPC: F26B17/14
Filed: 1990-05-30
Abstract: PURPOSE:To improve the dry efficiency of grains and to prevent a mottled drying by controlling the dehumidification air capacity to be sucked up by an exhaust fan based on time elapsed from the start of dry operation and the moisture of the grains, and the amount of grains to be delivered by a delivery valve so that the grains may be dried up. CONSTITUTION:All the exhaust air to be sucked up and exhausted by an exhaust fan 5 is controlled based on the time elapsed from the start of dehumidification/dry operation and the moisture of grains in the early stage of dry operation. The exhausted air is controlled so that it may not be reduced. The open air to be sucked up into a dehumidification device is controlled so that its capacity may be increased to a large extent while the dehumidified and dried air is controlled so that its air capacity may be increased to a large extent. The amount of delivered grains which flow down by a delivery valve 2 is controlled so that the grains may be increased to a large extent and dehumidified and dried. In the middle period of dehumidification/dry operation, the exhaust air from the exhaust fan 4 is partially controllably reduced to the dehumidification device 3 where the open air capacity to be inhaled into the dehumidification device 3 is controlled so that its air capacity may be middle while the dehumidified and dried air is controlled so that its air capacity may be standard. Moreover, the amount of grains to be delivered by the delivery valve 3 is controlled so as to conform to a standard air capacity. In the latter period of dehumidification/dry operation, all the exhaust air from the exhaust fan 4 is controllably reduced to the dehumidification device where the open air to be sucked into the dehumidification is controlled so as to keep a small air capacity while the dehumidified and dried air is controlled so as to keep a standard air capacity.

Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide an evaluation method in which a dynamic electricity phenomenon can be evaluated in a many-sided manner by a method wherein a zeta potential is computed on the basis of data obtained by measuring the dynamic electricity phenomenon of a solid- liquid interface a plurality of numbers of times and the zeta potential is captured as a distribution amount which expresses its electric charge state so as to be processed on the basis of a statistical technique. SOLUTION: A solid sample whose zeta potential is to be measured is filled between an electrode 1 and an electrode 2 inside a cell 10, and a filled layer 3 is formed. A liquid which is made to flow into the cell 10 is housed in a fluid-liquid supply container 11, and the pressure at the inside of the supply container 11 is made higher than atmospheric pressure while valves 17a, 17b at a fluid-liquid receiver container 12 and values 14a, 14c at the supply container 11 are opened and closed. In this state, the liquid inside the supply container 11 flows to the cell 10, and a fluid potential E which is generated in the filled layer 3 is measured by an electrometer 13. The output of the electrometer 13 and outputs of pressure gages 15a, 15b are input to a computer 22 via respective A/D converters 21. Then, a zeta potential ζis found by ζ=k.E/P [where (k) represents a constant] on the basis of a fluid pressure P which is found from the pressure difference between the pressure gages 15a, 15b and on the basis of the fluid potential E. By a computing operation based on a statistical technique, the mode value, the mean value, the standard deviation and the like of distribution amounts are found.

Title: Construction of drum head
Inventor: ROBAATO SHII BIIRUSU
IPC: G10D13/02
Filed: 1988-06-13
Abstract: PURPOSE: To prevent the detachment of an adhesive material for fixing a drum head to a metallic hoop from this hoop by disposing a spring clip for fixing the butt joint part to be formed between the two ends of the hoop. CONSTITUTION: An internally bent edge makes an interference fit with a polyester resin 38 in order to strengthen the hoop 20 and to mechanically fix the resin within a groove 22. A diagonal rim 44 existing on the inner wall of the groove has the same angle as the angle of the flange of the drum head 10 and, therefore, the flange 18 is flatly pressed and mounted to the diagonal surface without coming into contact at all with the sharply pointed rim 44 which causes undue wear or applies cutting force or other parts. Simultaneously, the large contact surface between the drum head 10 and the diagonal surface prevents the incidental spillage of the resin from the groove 22.  The clip 36 fixing the butt joint part of the hoop 20 fits so as to press the wall of the groove 22 by spring force and is nabbed by the internally bent edge of the groove 22 and the pointed teeth 46 existing at its flank bite into the inside wall of the groove 22, thereby securely connecting the groove.
