Title: Sintering method of nitrogen-containing cermet
Inventor: TOBIOKA MASAAKI
IPC: C22C29/04
Filed: 1985-02-14
Abstract: PURPOSE:To produce nitrogen-contg. cermet having high strength by subjecting an alloy which is specified in the content of Ti and Ni of the hard phase consisting of the carbonitride of Ti, Mo and W and is specified in the content of the bond metallic phase consisting of Co and Nio sintering, preserving and reheating under specific temp. conditions. CONSTITUTION:The carbonitride of 1 or 2 kinds of Mo and W and Ti is used as the hard phase and the content of Ti in the metallic atoms in said hard phase is specified to 0.5-0.95 by atomic ratio and the content of the nitrogen in the non-metallic atoms is specified to 0.1-0.3 by atomic ratio. The binding metallic phase of the remaining part is constituted of 1 or 2 kinds selected from Co and Ti and is incorporated at 3-50wt% into the alloy. The nitrogen- contg. cermet made of such compsn. is sintered at 150 deg.C of the temp. at which the liquid phase is produced or above and <=300 deg.C and thereafter the cermet is held for >=10min at the temp. lower by 100 deg.C than the temp. at which the liquid phase is produced. Such cermet is subjected to the reheating treatment at 150 deg.C of the temp. at which the liquid phase is produced or about nd <=300 deg.C. The strength of the nitrogen-contg. cermet is thus remarkably improved.

IPC: G03C5/00
Filed: 1991-02-22
Abstract: PURPOSE:To record information inexpensively and easily by doping or dedoping it partially on a specified thin film before developing. CONSTITUTION:Doping or dedoping is partially carried out on a thin film, consisting of a high molecular compound mainly having conjugation in its principal chain, being capable of doping or dedoping and soluble by a solvent in a state of being not subjected to the doping, and a part not doped is solubilized by the solvent and removed away. For example, diphenyl ionium hexafluoroalsinate is solubilized in a solution in which poly-3-dodecylthiophene is dissolved in chloroform, and a mask is attached to the surface of a film to be secured by drying after casting it on a glass substrate, then light of a tungsten lamp fitted with an infrared cut film is radiated thereto. In addition, a soluble part is dissolved by the chloroform, through which there are leftover such parts exposed to light, thus a pattern of the mask is recorded in a clear-cut manner.

Abstract: PURPOSE:To turn an output terminal to a floating state when an operation is turned off. CONSTITUTION:By turning off a constant current source CS, transistors Q3, Q15 and Q14 are turned to an off state. Then, the output terminal OUT is turned to the floating state. Also, when a power source VCC falls to a ground potential, the bases of the transistors Q14 and Q15 become the ground potential, the transistors Q14 and Q15 are turned off and the transistor Q3 is not turned on either, since the emitter of the transistor Q3 becomes the ground potential. Thus, the output terminal is turned to the floating state even in this case, and adverse influence is not exerted on the output terminal even when this amplifier is turned off while the output terminal is kept connected.
