Title: Hot water heater with reheating of bathtub water
Inventor: YAJIMA TAKUYUKI
IPC: F24D3/08
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in a heating capacity at the time of operating with reheating of bathtub water and heating. SOLUTION: This water heating and room heating equipment 1 has a water heater 2 for supplying a hot water to a room, a bath and the like, and a water heater 5 for room heating to supply hot water to a plurality of radiators 3 installed in rooms. The heater 5 is accompanied with a reheater 6 of a bathtub water and installed in a single casing 7. The heater 5 has the radiator 3 for room heating, a heat exchanger 27 for room heating, an expansion tank 20, a hot water heater pump 19 for circulating room heating water between the radiator 3 and the exchanger 27, and a by-pass mechanism for by-passing and combining the circulating forward heating water to the return heating water. The reheater 6 has a bathtub 21, a heat exchanger 2 for reheating of the bathtub water, a bath circulating pump 25, and a temperature detector 28 for detecting a temperature of the reheating hot water.  Since a by-pas motor driven valve 30 for controlling a by-pass amount based on a detected output of the detector 28 is disposed in the mechanism, a decrease in the heating capacity due to the reheating accompanied with room heating can be suppressed as much as possible by regulating an opening of the valve 30.

Title: Wire for welding and welding method
Inventor: GODAI TOMOKAZU
IPC: B23K35/30
Filed: 1979-07-07
Abstract: PURPOSE: To decrease the residual stress of welded part and improve toughness by TIG welding Ni-steels for low temperature use by the use of an eutectic Ni alloy wire of limited composition.  
     CONSTITUTION: The composition of the welding wire comprise essentially 8W15% Ni and 0.1W0.8% Mn based on weight as well as ≤0.15% silicon, ≤0.1% C, ≤0.1% Al and ≤0.1% Ti. Boron is kept at ≤0.003% based on weight and oxygen and nitrogen are kept at ≤200ppm respectively. Next, ultra-low-temperature steels containing 8.5W9.5wt% Ni are TIG-welded, by using this wire. The reasons for limiting the compoment ratio are: at <8% Ni, toughness lowered at low temp. is and at >15%, ductility decreases. If Mn is <0.1%, workablility becomes low and blowholes are liable to occur, and if it exceeds 0.8%, toughnes is lowered. If the amounts of boron, oxygen and nitrogen exceed the specified amounts, toughness is lowered.

Title: Noise reducer
Inventor: ONO KOICHI
IPC: H04N5/21
Filed: 1989-04-07
Abstract: PURPOSE:To reduce color flicker at the upper part of a television pattern caused due to head changeover of a VCR by avoiding amplitude limit by a limiter circuit for a blanking period or a period equivalent thereto. CONSTITUTION:The amplitude limit by a limiter circuit 24 is stopped for a period just after head changeover or for a horizontal blanking period when a burst signal exists. Since a signal 17 multiplied with a prescribed coefficient with a difference signal 16 is supplied to a subtraction circuit 8 independently of the magnitude of the difference signal 16 for a limiter release period, even when the noise component included in a signal 11 is large, the noise is sufficiently reduced. Thus, the disturbance of a burst signal just after the head changeover at VCR reproduction is suppressed smaller and color flicker on the upper part of the television pattern is reduced.
