Title: Water purification system by reverse osmosis and booster pump therefor
Inventor: IBUAA SHIEENMAIA
IPC: C02F1/44
Filed: 1995-04-28
Abstract: PURPOSE: To prevent the degradation in the pressure increasing ratio of a pump by providing the system with a piston detecting means which opens a first valve when a piston arrives at a stroke position and opens a second valve when the piston arrives at a return position and a returning means which opens the first valve to move the piston to a return position.  
     CONSTITUTION: When the piston 36 arrives at the stroke position, the detecting member 88 comes near to a second transducer 86 and emits an input signal to a control circuit 90. A first solenoid control valve 80 turns on and a second solenoid control valve 82 turns off, allowing feedwater to flow through a first supply port 28 from a water filter 16 into a return chamber 44. The force of a return spring 45 and the pressure of the feedwater in the return chamber 44, thereupon, overcomes the pressure of the feedwater in a stroke chamber 42 and, therefore, the piston 36 moves to the return position and the water pressure in the stroke chamber 42 rises. The pressurizing water in the piston chamber 58 opens an intake valve 62 to admit the feedwater in the stroke chamber 42 into a pressurizing chamber 46. Not only the feedwater pressure is increased but also the continuous self-flashing of a reverse osmosis membrane 18 is induced.

Title: Position registration method
Inventor: SUZUKI YUKIHIKO
IPC: H04B7/26
Filed: 1993-04-30
Abstract: PURPOSE:To reduce wear of a battery of a mobile station and to relieve the load imposed on a base station by setting a moving range from a mobile speed of the mobile station and registering the position at a point of time when the mobile station is at the outside of a mobile range so as to reduce number of times of position registration of the mobile station. CONSTITUTION:A mobile station P moving a service area having plural zones covered by plural base stations each connecting to an exchange station is located. The mobile station P calculates a position reached when the station keeps moving for an elapsed time at a registered speed from a point A being a registered position, that is, a predicted position X1. A proper range around the predicted position X1 is referred to as a predicted zone Z1. When the mobile station P is called and a point at the outsize of the zone is not within the predicted zone Z1, the position is registered again at that point of time and when the mobile station P stays within the prediction zone Z1, the position is not registered but the mobile station P keeps travelling as it is. Thus, number of times of position registration is decreased, the load of the base stations is relieved and the radio wave is effectively utilized.

Filed: 1995-05-26
Abstract: PURPOSE: To eliminate the need of packaging at a shop by a method wherein two or more products are packaged in a bag having handles on the opening side and the handles are weakly adhered together to seal off the bag. CONSTITUTION: Handle holes 3a and 3b are formed near the open ends of the long sides of two side panels of a bag 1. The bag 1 has an enough height to allow sealing the open ends of the bag 1 after a pile of five video tape cassettes 2 is put in the bag 1. A weak adhesive agent 4 is applied on a specified areas along the open ends that form handles of the bag 1 together with the handle holes 3a and 3b. After the five video tape cassettes 2 in a pile are put in the bag 1, the open ends of the bag 1 are sealed by the weak adhesive agent 4 to form a package. The bag 1 of the package serves as a packaging bag when the weak adhesion on the open ends of the package is peeled off, that provides such a merit that the need of packaging at a shop is eliminated.

Title: Background noise renewal system/method
Inventor: NOMURA SHIGEO
IPC: H04B14/04
Filed: 1995-05-26
Abstract: PURPOSE: To renew the generation of background noise when background noise renewal information is received in a facing radio movable station or a sound processor in a VOX control system in a movable communication system. CONSTITUTION: The sound/silence judgement of input sound information is judged in a radio movable station 30. A sound preamble is transmitted to a radio base station 31 through a radio line prior to encoding sound information at the shift time of sound from silence. At the shift time of silence from sound, the transmission of encoding sound information to the radio base station 31 is stopped, and background noise renewal information is transmitted at every prescribed time and VOX control is executed during silence. A sound processor 32 receiving background noise renewal information transmitted from the radio base station 31 through a communication line 34 stores received renewal information, and adopts it at every two information, for example, by using stored renewal information. The renewal period of background noise transmitted to an exchange transmission network 33 becomes long and the change of background noise does not become frequent. Thus, noise dose not become jar on one's ears.
