Title: Safety device in heat treating furnace
Inventor: TANAKA SHIYUUICHI
IPC: B22F3/10
Filed: 1983-12-26
Abstract: PURPOSE:To maintain always the gas in a heat treating furnace in a non-explosive state by providing a mechanism which feeds an inert gas into the furnace and to release the explosive gas therefrom when the oxygen ratio in the furnace approaches to the explosion limit ratio. CONSTITUTION:The oxygen ratio in a vacuum sintering furnace 1 is detected by an O2 sensor 5 and is transmitted via a converter 6 to a control means 7. When the oxygen ratio in the furnace attains the value near the explosion limit ratio, the means 7 outputs a danger signal O to solenoid valves 9, 10 to open the valve 9, thereby feeding an inert gas from a storage device 8 to the inside of the furnace through the supply path (c) and at the same time said means opens the valve 10 to expel the gas in the furnace to the external atmosphere through the release path (d), thereby decreasing the oxygen ratio in the furnace. An explosion accident is thus prevented.

CONSTITUTION:At the time of utilizing the heat accumulated in a heat storage tank 2 in use of a heat exchanger 1, a primary side pump 3 and a secondary side pump 7 are operated. In this case, an automatic ON-OFF valve 12 is kept closed so that the heat in the tank 2 is transferred through a primary piping part 5 and a heat exchanger 4 to a secondary apparatus 6 at a secondary piping part 8. When the heat from the tank 2 is insufficient, an operation of a pump 10 and opening of the valve 12 are carried out additionally, whereby heat from a heat source apparatus 9 is added to the heat fed from the heat exchanger 4 to the secondary apparatus. The heat exchanger enables division of the system into the primary piping part comprising the heat storage tank, etc. and the secondary piping part comprising the heat source apparatus, secondary apparatus, piping, etc. It is therefore possible to form the secondary piping part as a closed piping system, prevent the dissolution of oxygen, which would cause corrosion, and to prolong markedly the useful life of the apparatus and piping in the secondary piping part.

Title: Optical recording medium
Inventor: FUCHIGAMI YASUKO
IPC: G11B7/24
Filed: 1988-10-04
Abstract: PURPOSE:To hardly generate incomplete erasing at the time of erasing by interposing a required heat insulating layer between upper and lower layers which form the recording medium. CONSTITUTION:The lower layer 2 consisting of an org. dye recording material which expands by absorbing a recording beam and the upper layer 3 consisting of an org. dye material which absorbs an erasing beam and allows much transmission of the recording beam while partly absorbing this beam are formed on a substrate 1. The heat insulating layer 6 which prevents the transfer of the heat of the layer 2 by the absorption of the erasing beam to the layer 3 and allows the transmission of the recording beam is interposed between the layers 2 and 3. The erasing beam at the time of erasing is absorbed into the layer 3 by this layer 6 and the layer 3 is softened to a rubber state from a glassy state and is restored together with the rubber-like layer 2 to the state before recording. The incomplete erasing of the recording bumps is thus substantially prevented; in addition, the layer 6 allows the transmission of the recording beam and, therefore, the recording is executed without hindrance.
