Title: Upward-flow filter
Inventor: YAMADA SADAO
IPC: B01D29/62
Filed: 1979-01-25
Abstract: PURPOSE: To regenerate filter medium without causing abrasion, by, in passing water upward through a filter tower contg. the filter medium of specified specific gravity, settling the muddy material from the filter medium in the filter tower while the filter medium being stirred up, then by passing water downward after the filter medium is agitated.  
     CONSTITUTION: The raw water contained in a tank 4 is charged by a pump P 1  upward to a filter tower 1, which is packed with filter medium such as PE pellet of a a pellet diameter about 0.5W1.5mm and a specific gravity not larger than 1, in order to capture with filter layer 3 the muddy material which floats and accumulates under an upper water-collecting plate 2. The treated water is discharged through the tower top and a pipe 6 to a tank 7, where it is stored. After filtration for a prescribed time, or when the filter 3 is filled with the captured muddy material and indicates a prescribed head loss, the filtration is stopped and the regeneration is started. The regeneration is carried out by blowing air from a compressor C through a pipe 8 in order to stir the filter medium in the tower.

Title: Transformer device for high voltage generation
Inventor: YOSHIDA SHOJIRO
IPC: H01F38/42
Filed: 1989-01-13
Abstract: PURPOSE:To lower the peak value of pulse voltage at the final end of a wiring in each layer by making larger the permittivity of an insulating layer provided between the adjacent layers in the vicinity of the final winding end than in the starting end of each wiring. CONSTITUTION:The dielectric constants of dielectric films 9a-9d of an insulating layer 9 provided between the secondary windings of a flyback transformer are defined to be 9a<9b<9c. The films 9a-9c are sticked to each other, arranged parallely to the film 9d. Insulating layers A-C are constructed with the films 9a-9c in the layer 9, and elements C3-C1 having lumped constants are formed at portions of the layers A-C. Once a pulsed current flows through a primary side, voltages of respective pulse voltage sources en are added and applied to respective capacitors C1-C3. Since the permittivities of the films 9a-9c are set 9a<9b<9c, the capacitance of the respective capacitors satisfy a relationship C3<C2<C1. Therefore, the peak value of the pulse voltage in the vicinity of the winding end of the wiring can be lowered.
