IPC: F24H1/10
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure in a water piping from rising abnormally due to thermal expansion of retained water in a heat exchanger. SOLUTION: A heating-times control device 40 is provided, and when a temperature detected by a hot water detector 25 does not rise to an initial set temperature or above even if heating of a heat exchanger 17 is performed by specified times while flow of water is not detected by a water amount detecting means 20, heating of the heat exchanger 17 is stopped. Thus, the pressure in the water piping in a hot water supply device 26 is prevented from rising abnormalily, and the temperature of retained water in the heat exchanger 17 is kept at a constant temperature or above within a range of normal pressure, thus a hot water is supplied quickly at starting of hot water supply.

Title: Preparation of metal carrying catalyst with high surface area
Inventor: POORU SUTONHARUTO
IPC: B01J21/18
Filed: 1991-12-13
Abstract: PURPOSE: To provide a method for preparing a large surface area noble metal carrying catalyst, by which a catalyst metal is reduced with high dispersibility and with a uniform particle size on a carrier and a single metallic form with a superior resistance to sintering is deposited, by using a reducing agent having weak reducing power as a reducing agent and incorporating a sulfur atom. CONSTITUTION: A large surface area metal carrying catalyst is prepared by reducing metal containing ions in a solution of the metal containing ions with one or more kinds of reducing agents selected from thiourea and thioacetamide and by depositing the large surface area metal on a carrier. Reducing power of a reducing agent incorporating sulfur is comparatively weak so as to uniformize particle sizes. Furthermore, because metal particles grow utilizing sulfur atoms, which are separated in a reduction step, as nuclei, this tendency becomes still more notable.
