Title: Explosion-proof unit for refrigerator
Inventor: TAKEDA YASUHITO
IPC: F25D11/00
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the problem of cost increase due to provision of a plurality of gas sensors for ensuring sufficient safety being required because a large number of switches, electric contacts, heaters, and the like, are provided generally in a refrigerator in order to turn a motor on/off by detecting the temperature in the refrigerator and because the majority of refrigeration cycle is installed in the cabinet of the refrigerator. SOLUTION: A refrigerator having a refrigeration cycle employing a combustible coolant is provided with an outer air temperature sensor 11 and a temperature sensor arranged in the delivery tube 12 of a compressor 1. A microcomputer makes a decision that the gas has leaked if the temperature of the delivery tube detected through the temperature sensor 11 during operation of the compressor 1 is abnormally lower than the outer air temperature. When a decision is made that the gas has leaked, power supply to the refrigerator is interrupted to stop the system.

Title: Continuous production of aluminum nitride
Inventor: MATSUDAIRA YASUSHI
IPC: C01B21/072
Filed: 1990-06-27
Abstract: PURPOSE:To continuously and efficiently obtain high-purity AlN at a low cost by continuously introducing a mixture of aluminum hydroxide with a carbonaceous substance at a specific ratio into a tunnel kiln and reacting the mixture with countercurrently introduced nitrogen gas at a specified high temperature. CONSTITUTION:A mixture of 70-75wt.% aluminum hydroxide with 30-25wt.% carbonaceous substance (e.g. carbon black) is prepared. The resultant mixture is then continuously fed into a tunnel kiln and brought into contact with nitrogen gas introduced countercurrently in the transfer direction of the mixture at 1600-1700 deg.C temperature to initiate reaction expressed by the formula. Thereby, aluminum nitride is continuously produced. As a result, since CO, H2O gases, etc., formed by the reaction are directly discharged to the outside of the system and the reaction product is constantly brought into contact with the fresh nitrogen gas to completely finish the reaction, the objective high-purity aluminum nitride can be obtained.
