Title: Optical functional element
Inventor: ABE NAOMICHI
IPC: G02F1/17
Filed: 1987-03-25
Abstract: PURPOSE:To miniaturize and to improve functioning speed of an optical functional element by exciting molecules of the element with light and irradiating the molecules with second light having a different wavelength to the exiting light, thus allowing the element to function by the transmission or reflection of the second light due to the photoexcitation of the molecules. CONSTITUTION:Molecules are excited with light and the molecules are irradiated with second light having a different wavelength to the exciting light, thus an element is made to function by the transmission or reflection of the second light due to the photoexcitation of the molecules. By the irradiation of a molecule with light, the molecule is excited to an excited state of vibration or rotation of electron, and the excited state is switched to transmission or reflection of light having a different wavelength to the exciting light. Or, the element is allowed to function as a memory element by regulating the change between a ground state and an excited state to a change between 0 state and 1 state. By this constitution extremely high switching speed is obtd. Since, moreover, an element functioning as one molecule is also obtainable, the dimension of an element is miniaturized to a level of several Angstrom .

Filed: 1992-02-21
Abstract: PURPOSE: To improve the write speed of a page mode by improving a sense amplifier circuit, and to attain the reduction of an error ratio and low power consumption by reducing leak below a threshold value. CONSTITUTION: When a row decoder turns word lines WL0 and WL1 active, a sense amplifier 25a connected with each bit line pair in Tr 64-67 detects, amplifies, and latches the differential voltage of a bit line BL and an inversion BL, and stores it in memory cells 30 and 31. Then, the latched voltage can be read and written in a following cycle in a page mode, and when the page mode cycle is ended, the latch voltage updates and refreshes a bit stored in the selected memory cell. Then, after a prescribed time, the BL-and the inversion BL are separated from the sense amplifier, and equalization is started. An applied voltage is low at that time so that the leak of the memory cell can be reduced. Also, it is necessary only to charge and discharge the parasitic capacity of the sense amplifier latch 4 only at the time of writing, and efficiency can be attained.

Title: Method for washing filter element
Inventor: OGAWA TOSHIO
IPC: B01D29/62
Filed: 1982-04-28
Abstract: PURPOSE:To make it possible to simultaneously carry out the washing of a filter element and the internal purification of a filter vessel, by a method wherein the outside of a cylindrical filter element of which the outer peripheral surface is precoated with powdery ion exchange resin is filled with water while stirring and flowing action is imparted to filled water to carry out the washing of the element. CONSTITUTION:As a process for releasing resin, the supply of condensed water from an inlet 20 is stopped while water in a filtering and desalting vessel 6 is discharged from a pipe 28. When purified and filtered water 26 is introduced from the internal side of each element under pressure after all of water is discharged, the procoated resin layer 25 applied to each element is broken and released from the element by water discharged from the outer peripheral part of the element. Because the precoated resin 25 is high in specific gravity as compared to that of water, it is disharged out of the vessel from the pipe 28 along with water. When the interior of the element is filled with purified and filtered water 26 up to the upper part thereof, the greater part of the precoated resin is released and, therefore, when the mixing amount of resin in water discharged from the pipe 28 becomes little, the flowine of the pipe 28 is stopped. When the precoated part of the element in the vessel is covered with purified water, the introduction of purified and filtered water is stopped and water in the filtering and desalting vessel is stirred and flowed.

CONSTITUTION:A plastic pipe 7 is composed of the material different from the material constituting the main part 8 of the pipe to obtain stably the fitting parts 3, 4 with irregular shapes. This different material is the material having no compatibility and adhesivity with the material of the peripheral part 8 and its smooth surface, and then its curing speed is faster than that of the material of the peripheral part 8. As the combination thereof, there are e.g. the combination of olefin resin and rubber or metal and synthetic resin, etc., and the combination may be selected accordingly to its use. In the manufacture of the corrugated pipe 7, the parison obtained by extrusion is inserted into a corrugated forming machine, and the peripheral part 8, i.e. the side wall of the pipe is corrugation-worked. Then, the fitting parts 3, 4 are not deteriorated by the different material, and the parison shape is kept as it is. Next, the fitting parts are cut, and the temporary connecting rod 5 composed of the different material is taken out. Thus a product is obtained.
