IPC: H01L21/203
Filed: 1992-03-06
Abstract: PURPOSE:To obtain means for so forming wafers in a lot in size to be obtained in a latter half of a conventional lot that grain sizes of the wafers in the lot are uniform without increasing its cost by using an existing apparatus by providing a preliminarily heating step of previously heating an atmosphere in a chamber to a predetermined temperature before sputtering. CONSTITUTION:A method for forming a wiring has the step of film-forming a metal wiring material by sputtering in a chamber and comprises the step of preliminarily heating to previously heat an atmosphere in a chamber before sputtering. For example, a wafer is set in a preliminary evacuation chamber, the chamber is preliminarily evacuated, and is so previously heated as to reach a preliminarily heating temperature under predetermined conditions. When it reaches the preliminarily heating temperature, heating is stopped, the chamber is completely preliminarily evacuated, the wafer is then set in the chamber, started to be heated, set to a heating temperature during sputtering by a temperature control, and a metal wiring material is film-formed by sputtering.

Title: Combustion of pulverized coal
Inventor: KANEKO SHOZO
IPC: B02C23/32
Filed: 1989-03-03
Abstract: PURPOSE:To make it possible to provide pulverized coal combustion in which the concentrations of the unburned portion in ash and nitrogen oxide in the exhaust gas are both low and the ignition performance is excellent by specifying an air-fuel ratio respectively for a thick mixture gas and thin mixture gas and adjusting the degree of pulverization of the pulverized coal to a specified degree. CONSTITUTION:It is possible to adjust the grain size of fines, NOx, and unburned portion as desired and automatically by adjusting the rotational speed of a rotary classifying machine 65. When coal is pulverized to 85% pass at 200 mesh by an upright type coal pulverizer 1 which incorporates the rotary classifying machine 65, coarser gains over 100 mesh in the pulverized coal are reduced down to 0.1%. It is known that when the air-fuel ratio of a thick mixture gas is smaller than 1, unburned portion increases rapidly, and when the air-fuel ratio is over 2 the NOx increases rapidly. It is, therefore, desirable to adjust the air-fuel ratio of the thick mixture gas between 1 and 2 according to the requirments for NOx and the unburned portion. At this time the air-fuel ratio of the thin mixture gas is approximately 3-6. It is possible to adjust the rotational speed of the classifying machine in the above mentioned range by changing the angle of the classifying vane 75 with respect to the rotational direction.

Title: Measurement of radio wave generated in apparatus
Inventor: NAKAO TOMOYUKI
IPC: G01R29/08
Filed: 1988-03-03
Abstract: PURPOSE:To enable discrimination from extraneous radio waves by a single measurement, by providing antennas, one at a position near an apparatus to be measured and the other at a position away therefrom. CONSTITUTION:A first antenna 11 located near an apparatus 10 to be measured can receive intense radio waves generated from the apparatus 10. On the other hand, since a second antenna 13 is separated by a distance L from the first antenna 11, the intensity of radio waves generated from the apparatus 10 and received by the second antenna is weak to such an extent that it can be hardly detected. Extraneous radio waves arrive at the both antenna 11, 13 with the same intensity remaining unchanged independent to a distance L. Therefore, the radio waves detected by the respective antennas 11 and 13 are analyzed with separate spectrum analyzers 12 and 14 to be outputted. Output components existing in common in the both output of the spectrum analyzers 12 and 14 are determined to be those of the radio waves generated from the apparatus when they are more intense in the output of the analyzer 12 of the antenna 11 near the apparatus but less in the output of the analyzer 14 of the antenna 13 away therefrom. When there is no difference in intensity between both the output of radio waves, the radio waves can be judged to be extraneous radio waves.
