Title: Devices having shallow junctions
Inventor: HILLENIUS STEVEN J
IPC: H01L29/36
Filed: 1989-05-08
Granted: 1992-12-22
Abstract: Abstract In CMOS based integrated circuits, stricter design rules require source and drain junctions shallower than 2500 .ANG.. By using a specific device configuration, a shallow junction is obtainable while resistance to latch-up is improved and other electrical properties, e.g., low leakage current, are maintained. To achieve this result the p-channel device should have an activation energy of the junction reverse leakage current region less than 1.12 eV, with a junction dopant region shallower than 1200 A and a monotonically decreasing junction dopant profile.

Title: Method for producing glass preform for optical fiber
Inventor: ITO MASUMI
IPC: C03B8/04
Filed: 1989-06-28
Granted: 1996-04-02
Abstract: The present invention relates to a glass preform for use in fabrication of an optical fiber having no residual bubbles.  The glass preform is produced by depositing glass soot on a periphery of a starting glass rod to form a porous glass preform, heating and sintering the preform in a helium atmosphere to consolidate the preform and then heating the sintered glass in an atmosphere containing an inert gas, except helium, having a partial pressure of the inert gas of not lower than 0.8 atm.  A transparent glass preform is thereby obtained.

Abstract: There is provided a self-actuating, variable pitch propeller having a plurality of blades.  All of the blades are automatically movable between a first, relatively lower pitch position and a second, relatively higher pitch position, substantially simultaneously and equally in response to achieving a predetermined combination of propeller rotational speed and hydrodynamic loading on the propeller blades.  The blades are releasably locked to prevent pivoting of the blades, at least in the lower pitch position, but preferably can be locked in both the high and low pitch positions.  More preferably, a feedback force is transmitted from the blade to the locking means to vary the locking force in response to the net turning moment on the blade.  The locking means are released in response to the combined effects of centrifugal force generated by the blades and other portions of the propeller and the hydrodynamic loading on the blades.

Abstract: ABSTRACT             A user, through the use of a input device, provides signals indicative of x,y and z coordinates to a host central processing unit (CPU). Thex,y and z coordinates provided by a user correspond to a desired viewpoint for the display of an object stored in an original data image memory. A graphics CPU is coupled to the host CPU for receipt of the x,y and z coordinates as well as to the original data image memory. The graphics CPU is further coupled to a program memory as well as two display buffers, each of which of comprises a bit map of points on the display. The graphics CPU, executing a rendering program stored in the program memory, renders (writes) the data comprising the object for the viewpoint corresponding to the x,y and z coordinates provided by the user. After a predetermined percentage (N) of data comprising the object have been rendered into the non-displayed buffer, the graphics CPU signals a multiplexor which couples the display to the previously non-displayed display buffer, thereby displaying the predetermined percentage (N) of data which have been rendered. In the event that the user does not provide any new x,y and z coordinates representing a different viewpoint, the graphics CPU continues to render the data comprising the object into the displayed buffer, resulting in the appearance to the user that the object is "sparkling" into view. if, however, after the graphics CPU displays the predetermined N percentage of data points, the user provides new x,y,z coordinates corresponding to a different viewpoint, the graphics CPU ceases rendering the object data corresponding to the previous viewpoint, and begins rendering randomized data corresponding to the current viewpoint into the non-displayed display buffer.

Abstract: A cellular radio system comprises cells or cell groups (A1 to A3, B1, B2) complementing the network capacity locally. These cells or cell groups have not been presented as neighbouring cells for the surrounding network. This means that a mobile station (MS) of the cellular radio network will not at any stage become aware of these complementary separate radio coverage islands (A, B) on the basis of the neighbouring cell information received from a base station (BTS1 to BTS9). The coverage of these separate cells and cell groups (A1 to A3, B1, B2) may topologically overlap the other cells (C1 to C9) of the cellular radio network. An access of the mobile station (MS) to the cells of a complementary system is based on its a priori information of at which frequencies such a complementary radio coverage may be found (depending on the location of the mobile station). At least part of the mobile stations have then an automatic or user-operated facility of scanning these frequencies. Moreover, various checkings of access rights and various priority systems may be associated with the use of the complementary systems.
