Title: Automatic water supply system
Inventor: FUJINO KIYOSHI
IPC: H02J1/00
Filed: 1992-02-14
Abstract: PURPOSE:To obviate the necessity of electric work or battery change by sensing presence or absence of user while storing electric energy of solar cells in a storing means when the system is not operated whereas opening a solenoid valve with thus stored electric energy and collecting the electric energy generated from a hydraulic power generating means in the storing means when the system is operated. CONSTITUTION:When a flushing unit, for example, is not operated a storing means 5 stores power being fed from solar cells 3 under sunshine and a sensing means 2 senses presence or absence of user while being fed with power from the storing means 5. When a user is sensed, a water supply control section 6 delivers an open valve command signal 6d and a solenoid valve 7 is driven to open valve state mainly with power stored in the storing means 5. At that time, a hydraulic turbine 9a is rotary driven at high speed by the water flowing through a water supply pipe 8 to produce electric power from a generator 9b. Thus produced electric power is collected through a diode 10 to the storing means 5. Upon elapse of preset water supply time, the solenoid valve 7 is closed by a valve close command signal 6e to finish water supply operation.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent the development of surface defect by adding a projection having the same material as a pattern and the shape gradually reducing the cross sectional area toward the end part of molten metal stream or reducing step by step to the last reaching portion of the molten metal stream in a lost foam pattern, executing casting and removing the portions except the cast product shape after casting. SOLUTION: The lost foam pattern 2 is embedded in molding sand 4 filled in a molding flask 3. The poured molten metal reaches the lost foam pattern 2 through a sprue 5, runner 6 and gate 7, and the lost foam pattern is burnt and lost and gasified to form the cast product having the same shape as the lost foam pattern 2. This lost foam pattern casting method has comparatively small cross sectional area and can effectively be applied to the cast product having high height. In the case of arranging the conical projection 10 shrunk at the upper part in the upper end of the lost foam pattern 2, when the molten metal surface raises the portion of this projection 10, the molten metal pouring speed is reduced and shock is releaved, and on the surface of the cast product, the defect is not developed. This projection 10 is cut off and removed and can be used as a columnar body.
