Title: Backwashing method for filter
Inventor: IWANE HIROSHI
IPC: B01D29/62
Filed: 1992-08-07
Abstract: PURPOSE:To cause the agitating action of particulate matter in each layer of a filter medium to effectively remove foreign matter from the filter medium by intermittently feeding the backwashing water from the bottom part of a tank filter to above. CONSTITUTION:When filtration is performed within a specified time, foreign matter such as dirt accumulates in a filter medium 10, thus backwash is required. That is, after a circulating pump is stopped and simultaneously three- way switching valves 5, 7 are switched as shown by the solid lines, a backwash pump is operated, but its operation is intermittent, i.e., the feed and stoppage of backwashing water are alternatively repeated. Consequently, particulate matter in each layer of the filter medium 10 moves at random (up and down and right and left) to cause agitation action and foreign matter, such as dirt accumulated between particulates is forcibly suspended. The suspended foreign matter is discharged from the filter medium 10 together with next backwashing water.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To retain the endurance strength of a stop pin, and enlarge the relative rotatable angles of an input side plate and an output side hub, by forming a retaining member of a cylindrical member, retaining an interval between both input plates in a predetermined distance, arranging a fastening member by being passed through the inside of the retaining member, and fastening both plates. SOLUTION: A collar 21 is produced by a cylindrical steel pipe or carbon tool steels, and a connecting pin 22 is produced by a cylindrical material which can be rivetted, so that a stop pin is formed. Rivetting is executed to both end parts of the connecting pin 22 so as to form tightening head parts at both ends of the connecting pin 22 while the connecting pin 22 is passed through the hole 6b of the peripheral part of a retaining plate 6 and the hole 7b of the peripheral part of a clutch plate 7. This stop pin comprises two members 21, 22, therefore the conventional bent part does not exist. Therefore, a shell part, namely, the diameter of the collar 21 can be diminished by the part of the conventional bent part, and a relative rotatable angles of both plates 6, 7 against a spline hub 2 can be enlarged.

Title: Method for operating optical amplifier which is connected in chain mode
Inventor: EMANIYUERU DEZAABUIAA
IPC: H01S3/07
Filed: 1991-08-23
Abstract: PURPOSE: To suppress the accumulation of ASE noise, to amplify signal light and to improve an S/N in a coherent transmission system. CONSTITUTION: The plural light amplifiers OAs as many of them as possible of any one of distribution constant types, concentrated constant types and Er dope optical fiber types are connected in a cascade. For the pumping wavelength of an Er doped optical fiber amplifier, the wavelength for which the generation amplification of ASE is as short as possible is selected. When the sum of the signal light and the power of the ASE becomes close to saturation, since the S/N has deteriorated, the respective amplifiers are optimally controlled, corresponding to a signal level. An input end amplifier can be operated in a state, where the gain of signals is larger than the noise and an output end amplifier can be operated in the state where the gain of the signals is smaller than the noise.  The respective amplifiers are appropriately distributed to the three modes of free running, total power fixation and signal power fixation and operated, so as to enlarge the S/N as much as possible for the entire amplification system. Also, a filter Bo for transmitting the signal light is arranged on an output side for the respective amplifiers, in an effort to eliminate noise light.

Title: Reference voltage generating circuit
Inventor: OSHIMA YOSHIKAZU
IPC: G11C11/407
Filed: 1985-09-25
Abstract: PURPOSE:To generate a reference voltage by a small number of transistors (TR) while maintaining low current consumption by connecting TRs which have a common substrate and operate in a saturation and a nonsaturation region and a reference voltage generating element in series. CONSTITUTION:Transistors TRs 1 and 2 operate in the saturation region and a voltage nearly equal to a threshold voltage are developed between the source and drain of each TR. Then, TRs 3-11 operate in the nonsaturation region and are in charge of a voltage below the threshold voltage that the TRs operating in the saturation region can not be in charge of. Source-drain currents of the TRs operating in the nonsaturation region depend upon source-drain voltages applied to the TRs 3-11, so the plural TRs which operate in the nonsaturation region are connected in series to reduce an operating current. Further, the substrate of respective P channel MOS TRs is connected to a power source and the TRs 2-10 have back gate effect, so the threshold voltage of the TRs rises and the source-drain currents decrease.
