Title: Quartz glass doped with rare earth element and production thereof
Inventor: OYOBE AKIRA
IPC: C03C3/095
Filed: 1991-02-05
Abstract: Rare earth element doped silica glass according to the invention is prepared by doping silica-based glass co-doped with a rare earth element and aluminum additionally with fluorine and has excellent physical properties including remarkable light emission characteristics and an excellent capability of being fused with other silica-based glass.  Such doped silica glass provides high amplification gains and a wide wavelength bandwidth and therefore can be used as a material for manufacturing miniaturized optical devices.  Particularly, since the manufacturing process adapted to produce rare earth element doped silica glass according to the invention does not involve crystallization that normally characterizes the type of doped silica glass under consideration, the obtained doped silica glass is transparent and totally free from air bubbles.  As a method for manufacturing rare earth doped silica glass according to the invention combines means for producing articles made of porous glass and a solution impregnation method, it provides easy and effective means for manufacturing rare earth doped silica glass which is co-doped with both a rare earth element and aluminum and highly transparent and therefore can be used as a suitable material for active optical devices.

Patent CA-2065074-A1 (CA)
Title: Electric power cable line and a method of fabricating the same
Inventor: OOSHIMA HIROTO
IPC: H02G15/064
Filed: 1992-04-03
Abstract: An electric power cable line is arranged in which the insulating layer is increased to a greater thickness at two end portions of each cable than a thickness at the other or center portion of the same.  Since the insulating layer is increased in thickness at the end portions of the cable, thus an electrical stress exerted on the overall layer construction of the end portions is lowered.  Hence, the dielectric strength of the end portions of the cable becomes high and the power cable line will thus be increased in the operational reliability.

Title: Electronic shift or clutch actuator for a vehicle transmission
Inventor: REUTER DAVID C
IPC: B60K23/08
Filed: 1992-08-21
Abstract: The present invention is directed to an electronic actuator for use in a vehicle transmission such as a four wheel drive transfer case. In one preferred embodiment, the transfer case includes two separate electronic actuators, a range shift actuator which is utilized to effect shifting of the transfer case between high range, neutral, and low range drive positions, and a clutch actuator which is utilized to control engagement of a clutch between two wheel drive, automatic ("on demand" four wheel drive), and "part time" four wheel drive operating modes. The range shift actuator includes a rotary electric motor coaxially mounted relative to a rear output shaft of the transfer case, and a linear screw for translating the rotational movement of the motor shaft to selective axial movement of a range shift sleeve. The clutch actuator is similar to the range shift actuator except that, since the torque requirements necessary to bias the clutch are substantially greater than that necessary to effect the range shift, the clutch actuator includes additional gear reduction to enable the actuator to generate a sufficient axial force to fully engage the clutch. The actuators do not draw any current load after they have moved to their controlled positions and, because the linear screws can not be back driven, their previously set positions are maintained in the event of motor failure or power loss.
