IPC: C02F1/42
Filed: 1995-05-16
Abstract: PURPOSE: To provide alternate operation control system for water softeners in which the supply of soft water to the supply side does not stop. CONSTITUTION: A control system 6 for operating two water softeners 1A, 1B connected in parallel alternately. When a water sampling softener is changed over, after the confirmation of the supply of soft water from the changed-over water softener 1B, a regeneration command 7A is output to the water softener 1A before the change-over. When the confirmation is failed, abnormality is judged, and the water sampling softener is returned to the original water softener 1A in the control system. The confirmation of the supply of soft water is conducted by a signal from a flow rate mater 3 or a flow switch, a pressure sensor installed on the water sampling side, etc.

Title: Motor structure
Inventor: SUZUKI YUZURU
IPC: H02K37/14
Filed: 1995-06-07
Abstract: PURPOSE: To suppress the rotational fluctuation by making magnetic grooves in the vicinity of neutral point (border of N and S poles) of a rotor magnet and bringing the flux density distribution in the air gap closer to sinusoidal distribution thereby reducing torque ripple and cogging torque. CONSTITUTION: A rotor magnet 9 is magnetized with 16 poles and has magnetic grooves 2a-2p identical, in number, to the 16 poles. Each of the magnetic grooves 2a-2p is located at the switching point of pole (neutral point) and has a width corresponding to θ/2 of central angle from that point toward the N and S poles. The magnetic grooves 2a-2p reduce the surface flux density extremely as compared with other parts and the surface flux density distribution of rotor magnet 9 is brought closer to sinusoidal distribution. This structure reduces the torque ripple without lowering the motor efficiency and the torque constant thus suppressing the rotational fluctuation.

IPC: B29C45/37
Filed: 1986-06-19
Abstract: PURPOSE:To prevent the generation of warpage, torsion and a short shot, by pressurizing a core of a rule part immediately after an injection process and compressing a resin of the rule part. CONSTITUTION:A core 17 of a rule part 12 is set in such a state that the head of the core 17 is located in a cavity 18 at a position where a compression amount (alpha) is added to the objective thickness (t) of the rule part 12. Next, a thermoplastic resin 19 is injected in the cavity 18, and the rule part 12 is filled with the resin in a thickness of t+alpha. Immediately after the filling is completed, only the core 17 is pressurized to pressurize the thermoplastic resin 19 in the rule part 12 and the thickness of the rule part 12 is compressed to the objective thickness (t). At the time of the take-out of a product, the core 17 returns to the thickness of t+alpha to be separated from the solidified resin of the rule part. Therefore, the resin density of the rule part becomes high by compression, and the strength of a rule becomes great and hinge properties become good.
