Title: Moisture resistant molybdenum disulphide solid lubrication film and manufacturing method thereof
Inventor: LI HSIN-CHUNG
IPC: C23C18/16
Filed: 2000-06-30
Granted: 2003-09-21
Abstract: A kind of moisture resistant molybdenum disulphide solid lubrication film is disclosed, in which a adequate amount of metal (about 1-50 at%) is added into the molybdenum disulphide deposited film and the oxidation potential of the metal, such as titanium or chromium, is greater than that of the molybdenum. Therefore, the added metal can react with the oxygen and moisture in the moist air first to prevent the molybdenum disulphide in the molybdenum disulphide solid lubrication film from reacting with the oxygen and moisture in the moist air and thus maintain good solid lubrication property under high humidity (above 80% relative humidity) so that its friction coefficient will not increase sharply with humidity and time. Moreover, the added metal can densify the texture of the molybdenum disulphide solid lubrication film to obtain good mechanical property, such as increasing hardness from HV150 to above HV500, and still maintain its friction coefficient below 0.05 so as to continue performing its solid lubrication effectiveness.

Title: Negative feedback gain control for common electrode transistor
Inventor: FURINO JAMES JR
IPC: H03G1/00
Filed: 2001-06-18
Granted: 2002-11-21
Abstract: The unwanted variation in operating point associated with varying the gain of a common input/output electrode transistor, such as a common emitter bipolar transistor, is obviated by coupling an electronically controllable conductance in a negative feedback path between a first input/output electrode (collector) and the control electrode (base) of the transistor. A first embodiment applied to a bipolar device, the electronically controlled feedback element comprises a diode, having its forward conductance varied by adjusting current flow through a controllable current source. This controls the amount of feedback from the collector to the base and the forward loop gain of the common emitter transistor. A second embodiment for a bipolar device, the controlled feedback element comprises an emitter-follower transistor, with its forward gain controlled by varying the current drawn through its emitter by a controllable current source/sink. This, in turn, varies the amount of voltage fed back from the collector to the base and thus the gain of the common emitter transistor.

By means of the self-propelled body traveling along the lower traveling track, the model body is induced by magnetic forces to travel along the upper traveling track based on the racing game machine on which the model body travels. On the platen provided with linear motors at the lower traveling track is provided with an X-axis movable yoke and a Y-axis movable yoke on the underside of the self-propelled body, subjecting bearings to support the underside of the self-propelled body, such that the bearings cause the self-propelled body to travel along the lower traveling track. The induction magnet of the induced model body of the self-propelled body is made to allow rotation, so as to drive rotation of the induced magnet of the model body by means of a rotation driving motor. The induced magnetic body provided at the lower part of the model body and the induction magnet of the self-propelled body construct a torque transmission coupler. The rotation driving motor controls angle of the rotation of the induction magnet. The angle of the rotation of the induction magnet resulted from the rotation driving motor is controlled by the direction which the self-propelled body travels. Further, since the bearings are directionless, the bearings are able to support the self-propelled body and to cause the self-propelled body to move freely in any arbitrary direction on the traveling track.

Abstract: This invention provides a cutting method of processed object, formation method of predetermined cutting line and formation apparatus of predetermined cutting line by means of laser, which can cut processed object off without producing melting or crack outside the predetermined cutting line on the surface of said processed object. Pulse laser beam L irradiates on the predetermined cutting line 5 of the surface 3 of processed object 1, under the condition of generating absorption of multi-photons and the beam focusing point P being merged on the interior of processed object 1. Substance-change domain is formed in the interior of processed object 1 along the predetermined cutting line 5 due to the moving of the beam focusing point P along the predetermined cutting line 5. The processed object can be cut off with less strength by the cracking of processed object 1 along the predetermined cutting line 5 happened with the use of the Substance-change domain as a starting point. Upon the irradiation of the laser beam L, the surface 3 of processed object 1 doesn't absorb any laser beam L. Therefore, the surface 3 doesn't melt due to the formation of substance-change domain.
