The flowing hot water is cooled with the cooling fan 21 and stored in a hot water storage tank 13. When the temperature of the hot water drops to the predetermined level, the second temperature sensor 19 detects the temperature of the hot water and sends a signal to the controller 22. Upon receipt of the signal, the controller 22 actuates the second solenoid valve 20 and stops the cooling fan 21. As a result, the outlet of the hot water storage tank 13 opens and the hot water drops to a vessel 15 via a tea filter 14.

Title: Water level controller
Inventor: HANADA YOSHIYUKI
IPC: G05D9/12
Filed: 1988-01-14
Abstract: PURPOSE:To obtain a compact water level controller having high accuracy and high reliability by driving a motor-driven open/close valve based on the state signals of a level sensor and a switch. CONSTITUTION:When a water tank 1 is filled with water, the contact of a level sensor 5 is turned on and an open/close valve 3 is closed. In this case, a switch 8 is also turned on. When the water overflows out of the tank 1, a float 6 moves up to turn off the switch 8 and a signal (d) is turned off. Then a signal (e) is transmitted to open a valve 9 and an overflow state is displayed on a monitor device 10. When the water is discharged from a normally filled tank 1 with the valve 9 opened, both upper and lower contacts of the sensor 5 are successively turned off with drop of the water level together with the switch 8 kept turned on respectively. Therefore the occurrence of abnormality can be decided with the sensor 5 or the switch 8 and displayed on the device 10 via a control circuit 4 in case only the lower contact of the sensor 5 is kept off or both upper and lower contacts of the sensor 5 and the switch 8 are all kept off. Thus the accuracy and the reliability of an electrical system are improved for a water level controller.

Abstract: PURPOSE:To facilitate the variable speed control by performing the concurrent change-gear or change-gear through intermediate stages when the fluctuated rotating speed is high, and reversely when the fluctuated rotating speed is low, selecting an engagement/release pattern for avoiding the concurrent change-gear. CONSTITUTION:In an automatic transmission which consists of a first - a third epicyclic gear mechanism 1 - 3, clutches K1 - K4 and brakes B1 - B4 are selectively engaged/released to perform the predetermined change-gear.

Reversely, when the rotating speed of the predetermined rotating member such as the input shaft 4 exceeds the preset value, the concurrent change-gear or change-gear through intermediate stages is performed with an engagement/release pattern that the fluctuated rotating speed of any one of rotating member is low. Variable speed control is thereby facilitated, and while deterioration of a change-gear shock and lowering of the durability can be prevented.
