Title: Aqueous composition for removing heavy metal ion
Inventor: SASAKI NAOMI
IPC: C02F1/62
Filed: 1981-09-25
Abstract: PURPOSE:To obtain aqueous composition useful for removing heavy metal ions, by dissolving an organic sulfide compound prepared by bonding thiocarbonyl group-having low-molecular constitutive bodies symmetrically through sulfur in a solvent, and diluting it with water. CONSTITUTION:An organic sulfide compound prepared by bonding thiocarbonyl group-having low-molecular constitutive bodies symmetrically through sulfur is dissolved in a solvent, e.g. dimethyl formamide, butyrolactone or ethanol amine, which can be denatured into a water-soluble state, and diluted with water to prepare aqueous composition for removing heavy metal ions. The amount of water to dilute the solution is sufficiently effective at 5-50%, preferably 40- 45%. When said aqueous composition is added to a heavy metal ion-contg. solution, the capture of heavy metal ions is immediately started, and precipitation is advanced. The advancement of the precipitation can be confirmed by eye. When the advancement of the precipitation is stopped, the addition of the aqueous composition is suspended.

Abstract: PURPOSE:To obtain the subject fiber paper wound in the form of a roll, having high interlaminar strength and low thermal shrinkage and resistant to internal peeling and surface cracking by adding glass fiber, fibrillated fiber and thermally coagulable binder to ceramic fiber. CONSTITUTION:The objective ceramic fiber paper having an interlaminar strength of >=100g, a stiffness of <=1000mg, a thermal shrinkage of <2% and a thickness of >1.5mm can be produced by compounding 80-89wt.% of a ceramic fiber (e.g. alumina silicate fiber), 5-14.5wt.% of a glass fiber (e.g. chopped strand), 0.5-2.0wt.% of a fibrillated fiber (e.g. softwood pulp) and 2-7wt.% of a thermally coagulable binder (e.g. polyether urethane emulsion) and making a paper by conventional paper-making process. The addition of the fibrillated fiber causes the entanglement of the ceramic fibers free from self-adhesivity and the addition of the thermally coagulable binder uniformizes the distribution of the binder in the direction of thickness and prevents the delamination in the sheet.

Filed: 1989-06-14
Abstract: PURPOSE:To obtain the generator of simple constitution, in small size and inexpensively by providing a charging reactor, charging a charge/discharge capacitor with the electromagnetic energy therein stored when a switch means is deenergized, and controlling the energizing width of the switch means. CONSTITUTION:When a switch means 17 is suddenly deenergized, an electromagnetic energy stored in a charge reactor 12 charges a charge/discharge capacitor 14. When the charging is finished, a succeeding energizing signal a1 energizes the switch means 17 at the succeeding point of time. In such a case, the generation period of the signal a1 is made constant and the energizing width of the signal a1 is varied by a monostable multivibrator 21 in a control circuit 19. Thus, the energizing width of the switch means 17 is changed and the electromagnetic energy stored in the charging reactor 12 is changed. As a result, the charging voltage of the charge/discharge capacitor 14 is made variable. Thus, no output controller is provided to the power supply.

Abstract: PURPOSE:To reduce a telephone charge by setting a received phone call number, a time and a destination or the like so as to limit number of times of transfer thereby avoiding meaningless dialing. CONSTITUTION:When the mode is not the transfer mode after the reception of picture information at a receiver side terminal equipment, the terminal equipment receives the information in the usual mode and a recording section 3 prints it out. In the case of the transfer mode, 1 is incremented to a communication counter in a main memory 5 and the picture information is stored in a picture information memory 6. Then number of communication counters in the main memory 5 and a transfer designation item numbers are compared. When the communication count number is less than the transfer designation item number, the reception of succeeding picture information is awaited. When they are equal to each other, a telephone number of a transfer destination terminal equipment is read from the main memory 5 and the transfer destination terminal equipment is called. The transfer destination terminal facsimile equipment receives the call signal and proceeds the succeeding processing. On the other hand, when the receiver side terminal equipment confirms the connection with the transfer destination terminal equipment, the receiver side terminal equipment makes FAX transmission procedure and sends the picture information of a predetermined item number stored in the memory 6 to the transfer destination terminal equipment. The transfer destination terminal equipment executes FAX reception procedure and receives the picture information to be sent and uses a recording section 3 to print out the picture information.

Title: Attendant board connection system
Inventor: TAKAGI HIDEO
IPC: H04M3/60
Filed: 1985-07-10
Abstract: PURPOSE:To increase the chance of the switch board to handle other calls by releasing once the attendant board from the handling relating to a call and connecting the attendant board and a called extension before being connected to a trunk line call holding tentatively when the called extension is not proper. CONSTITUTION:When a reply extension SUB is not proper, the operator of the attendant board ATT depresses a split holding key. The key depression information is transferred to a central controller CC via a position equipment controller POSC. Both the extension subscriber SUB and the calling trunk line are preserved respectively and the operator of the attendant board is released from the operation and supervision of the call. The central controller CC gives a command to a switch controller SWC to control an exchange SW and the called extension SUB is connected to a call tone RBT. The called extension is intervened again at the reply and the two party talking with the called extension is attained again before the connection to the calling trunk line in this way, the chance in handling other calls is increased more than a conventional system.
