Title: Condenser
Inventor: KUSUKAWA YASUTA
IPC: F28B1/02
Filed: 1982-12-27
Abstract: PURPOSE:To increase reliability and durability, by preventing condensate streams falling from a group of cooling pipes from meeting exhaust streams from a turbine for driving a feed water pump. CONSTITUTION:The exhaust from a main turbine flows down from each upper opening 11, then after the exhaust is condensed by the cooling pipe groups 14, the resulting condensate falls from the cooling pipe groups 14 onto condensate receiving plates 19, and then flows through guide troughs 22 to reach opening sections 21 of hot well rool plates 17, from which it flows into hot wells 16. The exhaust from the feed water pump driving turbine is allowed to flow through feed water pump driving turbine exhaust pipes 18 horizontally into a space between each hot well roof plate 17 and each condensate receiving plate 19 in each condenser, diffuses in said space, and rises along the shorter sides 19c, 19d of each condensate receiving plate 19. Thus, the vertically falling condensate streams from the cooling pipe groups 14 and the horizontal exhaust streams from the feed water pump driving turbine are separated from each other by the condensate receiving plates 9 without meeting each other, so that the reliability of the condenser can be improved.

Title: Sound field adding device
Inventor: SAWAI TOSHIHITO
IPC: H04S1/00
Filed: 1990-09-03
Abstract: PURPOSE:To prevent a listener from feeling incongruous by compensating the difference in total sound volume between an actuation time and a non-actuation time of a sound field generation circuit by means of direct control of the reproduction level of sound. CONSTITUTION:When a sound field generation circuit is brought into an actuation state with a selection switch SW, a control circuit 6 controls switches 8B and 8C to be connected to the sides of a initial reflection generation circuit 4 and a reverberation generation circuit 5, respectively. At the same time, the control circuit 6 raises the amplification degree of an amplifier 2 to raise the level of a direct sound signal, which increases the volume of the direct sound reproduced by front speakers FL and FR. Accordingly, the total volume of the reproduced sound can be leveled off between the actuation time and the non-actuation time of the sound field generation circuit. Thus, an incongruous feeling given to the listener due to variance of sound volume can be prevented.

Abstract: PURPOSE: To eliminate the external piping for switching a passage and reduce the installation space and the cost by providing a compact switching vale in one heat storage gas burner to switch an air supply passage and an exhaust passage. CONSTITUTION: First, secondary air supplied from an air supply port is passed through a first heat storage unit 21, passed through a first passage 11, and burnt together with the gas of already burning state and primary gas. Exhaust gas is sucked from holes of a second group under the negative pressure control of an air supply port 35 from an exhaust port 36, retained heat is stored in a second heat storage unit 22 when it is passed through the unit 22, and exhausted. Then, when a switching valve 24 is driven to be switched, the secondary air is injected, burnt, while the exhaust gas is sucked from the holes of a first group, and its heat is stored in the unit 21. Thereafter, the heat of the unit 21 preheats the secondary air and the heat of the unit 22 preheats the secondary air, and hence the thermal efficiency is improved.
