Title: Discharge lamp lighting device
Inventor: SHIOMI TSUTOMU
IPC: B60Q1/04
Filed: 1992-05-15
Abstract: PURPOSE:To gradually darken a discharge lamp when a power source switch is OFF by varying the ON-duty or switching frequency of the switching element of an inverter circuit within a fixed time from the OFF-time of the power source switch. CONSTITUTION:When a power source switch S is ON, now, a capacitor C3 is charged to a fixed voltage determined by the divided voltage of resistors R1-R3 since a switch element Qx is OFF, and the duty of the output fH of a comparator CP1 in this case is constant. When the switch S is OFF, the electric charge of the capacitor C3 is discharged through the resistor R2, the element Qx, and the resistor R3, and voltage Vx across the capacitor C3 is gradually reduced. Thus, the ON-duty of a rectangular wave signal fH as the output of the comparator CP1 is gradually reduced in accordance with the reduction of the voltage Vx. Thus, the ON-period of the switching element of an inverter circuit is also shortened, and a discharge lamp is gradually darkened.

Title: Electrical hot water feeder
Inventor: YASUDA TADAO
IPC: F24H9/16
Filed: 1990-05-14
Abstract: PURPOSE:To reduce a mixing of hot water and cold water when the cold water is supplied, to take out a large amount of hot water and to perform a positive removal of water by a method wherein a connecting hole opened between a water draining pipe and a water supplying pipe of a T-coupling element is coaxially arranged on a water discharging valve and the connection of the water draining valve is carried out in concurrent with a closing of the water draining passage and another closing of the connection hole. CONSTITUTION:When water is to be supplied, water passes from a water supplying pipe 3 through a water supplying pipe passage 12 at a coupling element 11. The water is regulated to flow after striking against a flow regulating plate in the tank 1 to push up hot water silently which is boiled up in the tank 1 due to its difference in specific weight and then the hot water is fed out. At this time, a laminar flow is better obtained as compared with that obtained when cold water is supplied from a side surface of the tank 1 in a horizontal direction and no turburance flow is produced and so a mixing layer of hot water and cold water can be reduced. In addition, when the water is discharged, a mere opening of a drain valve 6 enables a positive water discharging within the tank 1 and the water supplying pipe 3 to be carried out. When the water is supplied, since the water supplying passage 13 and the water discharging pipe passage 12 are separated, so sediments in the tank 1 is not accumulated in the water supplying pipe 3 when the water is discharging into the water supplying pipe 13 and thus a clean water may always be supplied. In addition, since the T-coupling element 11 is disposed at a central part of a lower part of the tank 1, so that the water may easily be discharged and then a flow regulating effect can be increased.
