Title: Double shaft inversion centrifugal type fluid booster
Inventor: TATEISHI FUMIKO
IPC: F04D1/00
Filed: 1988-02-24
Abstract: PURPOSE:To reduce friction loss of fluid and boost efficiently pressure of fluid by introducing high speed fluid discharging from the outer periphery of a first impeller into a second to convert dynamic pressure to static pressure and then introduce the fluid into a casing. CONSTITUTION:A first impeller 3 is rotated through a shaft 2 by a motor 1 while a second impeller 6 is rotated through a shaft 8 by a motor 7. A swirl chamber 5 is formed between the respective impellers 3, 6, while a casing 9 is disposed on the outer periphery. High speed fluid discharged from the outer periphery of the first impeller 3 is introduced into the second impeller 6 to generate the relative speed in an inlet of the second impeller 6, while the speed of fluid in an outlet of the second impeller 6 is reduced to convert dynamic pressure to static pressure. Thus, friction loss is reduced by introducing fluid into the casing 9 with low speed so that fluid is efficiently boosted as a whole.

Title: Electrolytic protection method for duct and pipe
Inventor: NAKAMURA NORIMICHI
IPC: C23F13/00
Filed: 1988-02-24
Abstract: PURPOSE:To surely perform electrolytic protection of a duct or pipe connected to an iron reinforcing bar in a reinforced concrete structure by enclosing most of the region of the structure kept in contact with earth or water with electrifiers for vanishing macro-cells and by supplying electric current to the entire region kept in contact with earth or water. CONSTITUTION:In order to perform electrolytic protection of a duct or pipe 1 connected to an iron reinforcing bar 5 in a reinforced concrete structure 4, many electrifiers 2 for vanishing macro-cells are arranged so that most of the region of the structure 4 kept in contact with earth or water is enclosed with the electrifiers 2. An electrifying anode 13 is then placed so that the duct or pipe 1 and the bar 5 act as a counter electrode and electric current 20 for electrolytic protection is supplied to the entire region of the structure 4 kept in contact with earth or water. Macro-cell voltage Ec is minimized, contact resistance Rc is relatively increased and the dispersion of the electric current 20 is prevented to inhibit the corrosion of the duct or pipe 1.

IPC: H01H39/00
Filed: 1993-01-20
Abstract: PURPOSE:To make the operational continuance of an apparatus and a device in themselves impossible when the apparatus and the device are put in an abnormal condition. CONSTITUTION:Since a spherical electrically conductive body 2 is always pushed against/contacted with an electrically conductive body 4 by spring force (f) of an electrically conductive body 1, the electrically conductive body 1 and the electrically conductive body 4 are continued electrically to each other. Here, when external force F acts in a direction for overcoming the spring force (f), the spherical elecrtrically conductive body 2 slips out a central part hole of the electrically conductive body 1, and the spring force (f) of the electrically conductive body 1 is put out of the spherical electrically conductive body 2 so as to be unreturnable, and electrical continuity between the electrically conductive body 1 and the electrically conductive body 4 is lost.

Abstract: PURPOSE:To carry out efficient agriculture by a simple device, by equipping a long pipe with opening parts in the longer direction at proper intervals and dented parts for storing a nutrition solution, planting plants in artificial mediums set in the opening parts and sending the nutrition solution through the pipe. CONSTITUTION:A long pipe 1 is equipped with opening parts 2 in the longer direction at proper intervals and with a dented part 5 capable of storing a necessary amount of a nutrition solution after stopping of feed of the nutrition solution.

Title: Corotron for transfer
Inventor: TANAKA MASAYUKI
IPC: G03G15/16
Filed: 1985-03-04
Abstract: PURPOSE:To prevent specified ions from remaining nearby a photosensitive body by connecting a means which applies a plus and a minus voltage selectively to a discharge wire, and applying a voltage of the opposite polarity from toner during transfer operation and a voltage of the same polarity with the toner when transfer operation is not performed. CONSTITUTION:A high voltage power source 24 which generates a high plus voltage and a high voltage power source 25 which generates a high minus voltage are connected to the discharge wire 22 of a corotron 7 for transfer in parallel. Then when the transfer operation is performed, voltage of the opposite polarity from the toner, i.e. minus voltage is applied to the transfer corotron 7, but a selection switch 26 is changed over to its minus side right after the transfer operation to apply the plus voltage for several seconds. Therefore, when continuous recording is carried out, the minus and plus voltages are applied alternately. Consequently, H2OnH<+> ions generated during the transfer operation are neutralized by CO2 ions generated when the transfer is not performed, thereby preventing constant ions from remaining at the periphery of the photosensitive body 2.
