Title: Heat/cold storage apparatus
Inventor: YAMASHITA HISANOBU
IPC: F28D20/00
Filed: 1993-03-19
Abstract: PURPOSE:To provide a latent heat utilizing heat/cold/ storage apparatus in which the area of heat absorbing/ dissipating surfaces is increased without increasing in size to improve a heat exchanging efficiency. CONSTITUTION:A porous heat transfer material is brought into contact with a heat storage material 3 contained in a sealed vessel 2. Foamed metal 1 is placed in contact with the heat storage material 3 in a structure in which impregnation of the molten material 3 is prevented, and heating medium is fed to pores of the metal 1. The metal has a very large surface area to become heat absorbing/dissipating surface, and hence the heat exchanging efficiency is enhanced even if many thin pipes are not provided.

Title: Water-intake control method
Inventor: ITOU OSAMU
IPC: F04B49/00
Filed: 1978-05-22
Abstract: PURPOSE: To increase controlling accuracy by controlling a water-intake pump resulting from calculation of controlling parameters based on water-level in a water tank, water-level of water channel upper stream, and flow rate of intake.  
     CONSTITUTION: Water flows into a reservoir 2 from a river through an open  chnanel 1, and water-intake is operated by a pump 3 by pumping up the water from the reservoir 1 to another reservoir 4. A water-level gage 6 identifies water-level of the reservoir 2, while another water-level gage 7 is installed in the upper stream of the open channel 1. Difference of these two levels is calculated as well as discharge rate of the pump is measured to give a data to an arithmetic unit 9 which decides controlling parameters that can cope with possible flow rate change in a water system. Then the parameters are transfered to an indicating controller 5 to control the pump 3, thus highly accurate water-level control of the reservoir 2 is achieved.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a bagged 'futon' allowing a zipper to be smoothly opened and closed, and keeping the zipper free from becoming a problem, regardless of the status of the 'futon'. SOLUTION: Regarding the first and the second two halves 21 and 22 for separating an outer sheet into two parts, a gusset piece 60 is provided only along the periphery of the first half 21, and a zipper 70 is provided at the free end of the gusset piece 60. The zipper 70 has the first zipper member 71 at the free end of the gusset piece 60 and the second zipper member 22 along the periphery of the second half 22. Also, the first zipper member 71 has semi-circular part 71c and 71c near a start point S and an end point E, and a linear part 71 for connecting the parts 71c and 71c to each other. As a result, the constituent of the zipper 70 is not positioned at the back of a 'futon'. Also, the zipper 70 extends along the periphery of an outer sheet to form a part of a 'futon' body 30.  Thus, the zipper 70, when opened and closed, is subjected to the resilient force of the 'futon' body 3, thereby being opened and closed relatively smoothly.

Filed: 1990-03-12
Abstract: PURPOSE:To effectively develop a desired latent image area by making almost all amount of thin-layered developer which passes the tip of an electrode piece into powder-cloud state by the action of strong electric field and forming uniform high-density cloud on a developing area. CONSTITUTION:By rotating a developer carrier 101 and a latent image carrier 2, toner is attracted to the carrier 101 and a thin developer layer 107 is formed by a regulating charging member 103. At the same time, the layer 107 is charged by the friction with the carrier 101 and the member 103. The layer 107 is carried under a stirring means 105 and variable electric field is added to the layer 107 by the electrode piece 105b, then it is carried while it moves back and forth violently between the carrier 101 and the electrode piece 105b by the strong electric field between both of them. The developer layer is sprung out by the strong electric field of the tip 105c to become powder-cloud PC and dispersed on the developing area R. The developer collides mutually to be charged. With such constitution, the desired latent image area is effectively developed because the uniform high-density cloud of toner is formed on the area R.
