Title: Safety device for room heater
Inventor: TAKEDA MASAAKI
IPC: F24C7/08
Filed: 1987-02-19
Abstract: PURPOSE:To minimize trouble due to the contact by a person or object with the guard without deteriorating heat transfer efficiency, by detecting an electromotive force, generated by a piezoelectric oscillating body due to the fluctuation of a load, to stop the heating function of a room heater. CONSTITUTION:The title safety device is constituted of a piezoelectric oscillating body 5, providing a guard 3 with weak oscillation, and an oscillation removing body 8, preventing the oscillation from the piezoelectric oscillating body from being transferred to the main body 4 of a room heater through the guard. The change of the electromotive force of the piezoelectric body, which is generated by the load fluctuation of the piezoelectric oscillating body due to contact of a man or a subject with the guard, is detected. When the change is large, the heat generating function of a heat generating body is stopped. The piezoelectric oscillating body 5, effecting a stationary oscillation having a level integrated with the guard 3, generates a counter electromotive force therein due to the load fluctuation when a person or object contacts the guard whereby the level of the oscillation is reduced. When the safety device is designed so as to stop the heat generating function of a heat generating body by detecting the change of the oscillating level, the temperature of the heating body begins to descend thereafter, therefore, burn or fire may be minimized.

Title: Photoelectrostatic recording method
Inventor: SHIMAZAKI TAKASHI
IPC: G03G5/02
Filed: 1980-03-24
Abstract: PURPOSE:To eliminate the need for holding recording paper still in a charging process and make contrast sharp and a conveying device simple by performing required charging and transferring by dividing a recording electrode to a full surface charging part and a latent image forming part. CONSTITUTION:A recording electrode 23 consisting of a substrate 24, a conductor 26 and a photoconductor 27 are divided to a full surface charging part 23a and a latent image forming part 23b. A counter electrode 33 is provided in opposition to the electrode 23, and power sources 38, 42 of different polarities are connected between both electrodes. If with this constitution recording paper 32 moves in an X direction, it is exposed over the entire surface by irradiating light 28 in the charging part 23a, and positive carriers are produced in the photoconductor 27, thus the recording paper 32 charges uniformly to positive. Next, in the latent image forming part 23b, the paper is irradiated with image light 30 and the 1st latent image is formed in the conductor 27 by negative carriers. Thence, the image is transferred to recording paper 30, and the 2nd latent image 31 is formed. In this way, charging and transferring are accomplished by every one line. This results in increased potential difference between the image part and the nonimage part, hence sharpened contrast and since the recording paper does not stop still, the conveying device is simplified.

Abstract: PURPOSE: To cut down on the costs of chemicals and waste water treatment without impairing the regenerating capability by reusing part of waste water for regeneration in the early period of the subsequent regeneration when the regeneration of purified water manufacturing apparatus is made.  
     CONSTITUTION: The hydrochloric acid 11 for regeneration is passed through the cation exchange resion tower 2 for a certain time, and when the concentration of Ca 2+  and Mg 2+  in waste water falls down rapidly, the waste water is stored in the recovery tank 15 by the timer 13 and then reused for the regeneration of the exchange tower 2 through the piping 16 in the early period of subsequent regenerating operation. In the same way, in the anion exchange tower 3, the waste water, when the concentration of Cl -  and So -2   4  in NaOH solution for regeneration drops abruptly, is stored in the recovery tank 15' by the timer 13' and then reused in the early period of subsequent regenerating operation. Thus, chemicals for regeneration can be greatly reduced and the amount of waste water can be decreased without impairing the regenerating capability, so that neutralizing agent for waste water can also be reduced and waste water treatment cost can be curtailed.
