Title: Method for backwashing pleated film filter and filtration equipment using the same
Inventor: SATO YASUKIYO
IPC: C02F1/44
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To improve backwashing efficiency more than that attainable by a conventional backwashing method. SOLUTION: In this backwashing method, a group of box type members 30 used as a backwashing object selection means are placed on a perforated plate 10 so that the members 30 cover a part of the total number of the water collection members 10a, and accordingly, when a pleated film filter 2 is backwashed, each of sections of the filter 2 can be backwashed one by one separately from the other sections. Therefore, since the period of time for one backwashing run becomes longer than that in a conventional backwashing method, as a result, the backwashing can be performed for a longer time than that in a conventional method without interrupting the backwashing operation, to sufficiently secure the required amount of backwashing water for swell, release and outflow of suspended matter (filtration cake layer) deposited on the pleated film filter 2.  By using the backwashing method, even when the total backwashing time is the same as that in a conventional method, as compared with the conventional method, the total amount of suspended matter allowed to flow to the outside by the backwashing is increased and also the filtration pressure difference is remarkably reduced.

Title: Current detecting circuit for motor
Inventor: MIYATA TOMOJI
IPC: H02P27/08
Filed: 1991-03-26
Abstract: PURPOSE:To provide a circuit for detecting the current of AC motor accurately. CONSTITUTION:Motor current flowing through a current detecting resistor 16 can not be measured accurately as it is because a positive driving current and a negative flywheel current appear alternately through PWM switching. In the invention, an operating circuit comprising operational amplifiers 13, 14, 15 subjects a detected current to polarity conversion to produce a motor current waveform having continuous polarity which is then measured through a current measuring circuit 17 thus detecting the current.

Filed: 1993-03-22
Abstract: PURPOSE:To accurately detect the life of a discharge lamp by stopping the lighting of the discharge lamp when the integrating lighting time of the discharge lamp reaches a given value. CONSTITUTION:The lamp voltage VDL of a discharge lamp DL1 is gradually raised following lamp life performance, and when the value of the lamp life performance reaches some value, the life of the discharge lamp DL1 is expired.

Title: Resistor
Inventor: ONO YASUO
IPC: H01L27/04
Filed: 1986-03-19
Abstract: PURPOSE:To maintain the excellent linearity of resistance up to higher electric field without raising the carrier temperature by a method wherein semiconductor layers with the same conductivity type but different carrier concentration are alternately laminated in the current flowing direction. CONSTITUTION:A resistor is composed by alternately laminating semiconductor layers 3, 4 with the same conductivity type but different carrier concentration in the current flowing direction. Joule's heat is generated as usual in the low carrier concentration layer 4 comprising N-type Si 0.1mum thick in the current flowing direction in impurity concentration of 1X10<17>cm<-3> but less heat is generated due to weak electric field in the high carrier concentration layer 3 comprising N-type Si also 0.1mum thick in the current direction in impurity concentration of 1X10<18>cm<-3> to be let off in lattice efficiently due to the high carrier concentration. Through these procedures, the heat generated in the low carrier concentration is let off in the lattice not only on the spot but also through the high concentration carrier layer 3 not to raise the electron temperature. In other words, the linearity of resistance can be maintained up to the electric field higher than usual field.
