Abstract: PURPOSE:To improve the stability and the reliability by providing a thin plate diaphragm over a communicating part, and making a thin plate composing a lamination type displacement element of the electric mechanism converting material of which piezoelectric distorsion constant in a range of the specified temperature shows a constant value approximately. CONSTITUTION:A thin plate 24 composing a lamination type displacement element 21 is made of a lamination type displacement element (electric mechanism displacement material) of which piezoelectric distorsion constant d33 in a range from an ordinary temperature to a high temperature area more than 100 deg.C shows a constant value approximately. When a direct voltage is applied to the element 21, the element 21 is extended in the laminated direction to push down the central part of a diaphragm 17 downward through a valve rod 22, against the reaction force of a compression coil spring 27, and a space between the diaphragm 17 and a valve seat 15 is reduced, namely, the open degree of a valve port 16 is reduced to reduce a gas flow quantity. When the applying voltage to the element 21 is cancelled, the diaphragm 17 is returned to its original position. In this case, since a sliding part does not exist between the diaphragm 17 and the valve seat 15, the metal powder is never mixed with the gas.

Title: Magnetic cleaning device
Inventor: ASANAE MASUMI
IPC: G03G21/10
Filed: 1981-03-25
Abstract: PURPOSE:To improve the cleaning efficiency and to prolong greatly the lifetime of a cleaning member, by setting a magnetic member and a toner recovering roll at the lower part of a cleaning roll containing a cylindrical porous elastic matter fixed on a sleeve. CONSTITUTION:A magnetic member 7 is set within a range of the magnetic sucking force of a permanent magnet 6 and at the lower part of a cleaning roll 3 containing a cleaning member 5 made of a cylindrical porous elastic matter fixed on a sleeve 4. At the same time, a toner recovering roll 8 having a permanent magnet 10 is set in a sleeve 9. Thus the magnetic toner 2 stuck to the member 5 is detached from the surface of the member 5 at the position near the member 7 by the repulsion of the same polarity and drops into a recovering container 12. Some of the toner 2 is scattered in the opposite direction and adsorbed by the sleeve 9 to be collected into the container 12 through a scrape- off plate 11. In such way, the cleaning efficiency is improved and at the same time the lifetime is greatly prolonged for the member 5 since it has just a light touch to a photoreceptor 1.

Abstract: PURPOSE:To enable the loading efficiency to be augmented by allowing both panned loading information and loading work information to be operated based on the information which is stored in advance, permitting the resultant to be displayed, documented, and memoried, in a loading plan where various kinds of cargoes are mixedly loaded. CONSTITUTION:When a shipping cargo is designated by a light pen 21, a computer 10 reads out data for the cargo specification from an auxiliary memory 24, then, the data is set in a memory device 13 allowing it to be displayed 22. Subsequently, if the condition required for the planned loading is designated by an operator while the display 22 is being watched, the computer 10 determines the required number, the required size, and the allocation of a pallet. This allows them to be stored 14 and 15 permitting the loading allocation to be displayed 22. After being checked by the operator, it is inputted 21 as an acceptance signal. A coordinate for a loading position is stored 16 by the computer 10. The loading is performed while the loading position which has been already loaded, is being watched on the display panel 22. After the loading has been completed, the resultant is stored 17 allowing an automatic operation sequence to be determined, stored 18, and automatically processed. Thus, this configuration enables efficiency to be augmented.
