Title: Negative pressure, air volume adjusting method for glove box
Inventor: ASANO TAKASHI
IPC: F24F7/06
Filed: 1990-02-22
Abstract: PURPOSE:To adjust negative pressure in a glove box without changing the exhaust air volume, improve the safety by evaluating clogging of a filter accurately, and realize rational preliminary quality control by a method wherein the increase of pressure loss for a portion of filter clogging is adjusted by compensating with the decrease of pressure loss of valves for the system. CONSTITUTION:For a by-pass system 34, a micro differential pressure gauge 42 is provided. An air supply valve 22, air exhaust valve 26 and by-pass valve 32 are set under a throttle condition up to a certain degree at the initial condition. Under the initial condition, the apertures of the valves 22, 26, 32, which are located immediately behind respective filters 20, 24, 30, are throttled so that the same pressure loss as the filter's rated pressure loss is given, and is made that the total of both pressure losses becomes a required differential pressure for the system. When indicated values of a differential pressure gauge 16, negative pressure gauge 18 and micro differential pressure gauge 42 deviate from the initial set values during operation, the indicating value for each differential pressure gauge is returned to the initial value by adjusting all the valves to the opening directions. Thus, no matter which filter generates clogging, the increase of the filter pressure loss is compensated by the decrease of pressure loss of a valve which is located immediately behind the filter.

Title: In-furnace brazing method
Inventor: NISHIMURA MAKOTO
IPC: B23K3/00
Filed: 1980-04-02
Abstract: PURPOSE:To make it possible to form uniformly brazed joint by changing the heat receiving conditions by installing a heat isolating body having a prescribed oize at a prescribed location between the material to be brazed and heat source. CONSTITUTION:When material to be brazed 8 passes through the center of furnace by conveyor 1, the heat receiving conditins from heat source 5 become similar to those from pulse heating between heat isolating bodies 6, and, as the temperature of material to be brazed is raised, the temperature gradient which occurs at the material to be brazed becomes smaller. Therefore, by changing the heat receiving conditions of the material to be brazed in the furnace, uniformly brazed joint can be obtained quickly. Moreover, it is desirable to change the heat receiving conditions by moving or rotating either one of, or both of the heat isolating body and the material to be brazed against the heat source.
