IPC: B01D35/027
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent a supplying hot water pipe from taking out of a connecting section and from breaking when an internal pressure is raised according to a rising temperature of hot water reserved within an interior section at an operation for thermal sterilization by constructing the supplying hot water pipe in such a way that the hot water is slightly leaked in a closing condition of a prevention valve disposed at the supplying hot water section of the supplying hot water pipe for a weeping prevention. SOLUTION: When an operation for thermal sterilization is carried out, a temperature of hot water remained on the upper stream than a joint position of a bypass pipe 16 in a supplying hot water pipe 3 without being circulated is risen according to a rising temperature of hot water circulating in a closed loop and pressure is risen since a flow of the hot water in a direction to a bathtub 1 is stopped at a reverse stopping valve 14. Since a small hole 28 is provided at the valve body 27 of the reverse stopping valve 14, the hot water is reserved within the supplying hot water pipe 3 without being circulated, and rising of pressure according to the rising of temperature causes a flow through the small hole 28 of the valve body 27 in the direction to the bathtub 1, thus the pressure of the hot water within the supplying hot water pipe 3 is not raised.  The supplying hot water pipe 3 is not taken out of the connecting section by the rising pressure according to the rising temperature of the hot water reserved within the interior.

Title: Inverter
Inventor: NAKAGAWA NAOHITO
IPC: H02M7/06
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To enhance input efficiency without requiring significant modification of circuit or additional parts by providing an inductive load circuit for applying one rectified power supply voltage through a switching element, and a capacitor for arm connected at an intersection of the other switching element and the inductive load circuit. SOLUTION: If the instantaneous voltage level of a rectified power supply 40 is low, an arm capacitor 60 has a low voltage when a switching transistor 11 is turned on. Consequently, a high leftward voltage is applied to an inductive load circuit 50. Under that state, the voltage of rectified power supply 40 does not prevail and the output therefrom is suppressed. After a while, voltage of the arm capacitor 60 increases in the positive direction and the voltage of inductive load circuit 50 decreases. Consequently, the voltage of rectified power supply 40 prevails relatively to suppress discharge of a smoothing capacitor 30. According to the arrangement, power supply from the rectified power supply 40 is sustained even when the instantaneous voltage level is low and thereby the power factor is enhanced.
