Title: Vapor brazing method for al alloy containing mg
Inventor: KOYAMA KATSUMI
IPC: B23K103/10
Filed: 1989-09-12
Abstract: PURPOSE:To obtain an assembly excellent in surface treatment properties and corrosion resistance in post treatment by brazing a member of Al alloy containing a limited weight of Mg in a non-oxidizing atmosphere wherein a limited mmHg of chloride or fluoride flux vapor exists as the partial pressure. CONSTITUTION:When the member of Al alloy containing 0.3-1.2% Mg by weight is brazed through brazing filler metal, the member is brazed in the non-oxidizing atmosphere wherein 0.05-3.5mmHg of chloride or fluoride flux vapor exists as the partial pressure. At this time, since this vapor attaches uniformly to the member and breaks the oxide film on its surface, wettability of the brazing filler metal is promoted. Further, the vapor combines with water, oxygen in the atmosphere, makes the atmosphere of non-oxidizing properties and prevents oxidation of the member effectively.

Title: Image forming device and control method of fixation temperature
Inventor: FUKUSHIMA MASAHIKO
IPC: G03G15/20
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To make realizable an energy conserving mode, in which energy consumption of an image forming device is sufficiently reduced, by reducing the operating voltage of a second power supply to be not more than the normal operating voltage in a state where a first power supply is turned off in the energy-saving mode in which the first power supply is turned off. SOLUTION: When no action is performed for a prescribed time period while the power supply switch of an image forming device is turned on, the device goes into an energy-saving mode. In this mode, a control means CPU turns off a power supply EB. During an image forming period or a warm up time, the output voltage of a power supply EA of the means CPU is set to 5.2 V that is a rated voltage. However, when no action takes place after the power supply switch is turned on, for example more than 15 minutes, the means CPU executes a control to switch to the energy-saving mode, the power supply EB is turned off and the power supply EA is switched to a lower limit value of a rated range, i.e., 4.94 V or close to that value from the rated voltage 5.2 V.

The resulting sheet is subjected to decarburization annealing, coated with a protective coating material for annealing and coiled to form a loose coil having <=90% space factor. The coil is finish-annealed. In the finish annealing stage, N is infiltrated into the steel at 700-850 deg.C during heating before secondary recrystallization to form fine (Al, Si)N having the action of an inhibitor. Secondary recrystallization is then caused and a glass film is formed by the reaction of an oxide layer on the surface of the steel sheet with the protective coating material.
