Title: Installment chraging system for calling
Inventor: YAMADA TAKASHI
IPC: H04M15/08
Filed: 1978-02-25
Abstract: PURPOSE:In case the subscriber at the incoming side is stored in the exchange distant away from the mobile subsriber or from the original storage exchange due to the transfer service an other factors, the transfer destination information is memorized in the original storage exchange in advance and the charging is burdened to the subscriber at the incoming side. CONSTITUTION:Incoming-side subscriber 6 should be originally stored in exchange 4 but is stored in exchange 5 as a result of movement or by receiving the transfer service. Exchange 4 memorizes the current position of the transfer destination of subscriber 6. When originating-side subscriber 1 performs the operation to call subscriber 6, the connection is secured between subscriber 1 and 6 through the ordinaly way. In this case, the call frequency corresponding to section 7 up to exchange 4 to which subscriber 6 is originally to be stored is registered to call meter 10 of subscriber 1, and the call frequency corresponding to section 8 caused by transfer of subscriber 6 is registered to call meter 11 of subscriber 6 respectively. The charge to subscriber 6 can be set to the value obtained by subtracting the charge of section 7 from that of section 9.

Title: Filter and filtering method
Inventor: UIRIAMU FUREDERITSUKU BOUAASU
IPC: B01D33/00
Filed: 1988-02-02
Abstract: PURPOSE: To rapidly and efficiently filter a sample mingled with a dilute soln. and particles by using a vessel which is mounted with a special filtering cylinder and holds the sample of the liquid to be filtered and filtering the sample by utilizing centrifugal force. CONSTITUTION: The sample enters into the chamber part 60 of the filtering cylinder 40 through a filter 80 and a filter support 70 from the vessel 10 during filtration. The filtering cylinder 40 is forcibly sunk into the vessel 10 and a pressure head is created above the filter 80. When centrifugation starts, the filtering cylinder 40 tends to ascend in the vessel 10 by receiving the large buoyancy of the liquid from the sample, but the ridge 41 of the filtering cylinder 40 comes into contact with the inner edge 84 of a first cap 83 and, therefore, the filtering cylinder is maintained in such a state that the cylinder is forcibly sunk. The filtering cylinder 40 contg. the filtered liquid rides on the bed of the filtered particles entering the inside of a reservoir 110 under the filter 80.  The filtrate is easily inclined and discharged by removing the second cap 90 and pouring out the liquid.

Filed: 1979-02-26
Abstract: PURPOSE: To detect the charging state of ink particles with a simple method by applying the first search pulse for charging the ink particles and the second search pulse displaced in phase from the first search pulse to a charging electrode.  
     CONSTITUTION: A phase search signal b having very short pulse duration as compared with that of a particulation signal a applied to an ultrasonic vibrator with the same frequency as the signal a is applied to a charging electrode. A charging search pulse b-1 is applied in phase to the charging electrode in one half period of switching pulse C having 2.5kHz and a non-charging search pulse b-2 is applied thereto on the other half period of the pulse C. When the ink particles are normally charged at the application timing of the pulse b-1, the particles are not charged when non-charging search pulse b-2 is applied thereto. Accordingly, an electric current occured at the nozzle responds to the period of the pulse C.
