Title: Process for manufacture of mos gated device with reduced mask count
Inventor: KINZER DANIEL M
IPC: H01L21/28
Filed: 1995-08-17
Abstract: A reduced mask process for forming a MOS gated device such as a power MOSFET uses a first mask (33) to sequentially form a cell body (50) and a source region (51) within the cell body (50), and a second mask step to form, by a silicon etch, a central opening (80, 81) in the silicon surface at each cell and to subsequently undercut the oxide (60) surrounding the central opening (80, 81). A contact layer (84) then fills the openings (80, 81) of each cell to connect together the body (50) and source regions (51). Only one critical mask alignment step is used in the process.

Title: Process and apparatus for the agglomeration of hydrolytically sensitive substances by means of steam
Inventor: WALTER REINHARDT
IPC: B01F33/40
Filed: 1997-04-04
Abstract: In the process for the agglomeration of slightly soluble and hydrolytically sensitive substances, a powder of the slightly soluble substance is conducted, together with at least one water-soluble binder, in free fall through a steam atmosphere at temperatures between 85°C and 105°C essentially without the action of compacting forces. In this process, the residence time in the steam atmosphere is approximately 0.5 to 10 seconds. The agglomerates formed are then dried in free fall, so that small solid bridges form from the binder liquid bridges formed at the points of contact between the primary particles. In a following integrated fluidized-bed dryer, the final drying then takes place to a water content of less than 0.5 % by weight. The process is carried out in a steam jet agglomerator in which a freely falling product curtain of the pulverulent mixture to be agglomerated is impinged by steam using steam jet nozzles (5, 6). A fluidized-bed dryer (2) is connected at the lower part of the agglomerator (1) in such a manner that the agglomerated particles (4) fall directly into the fluidized bed.

Abstract: To increase reliability of telephone services in a local multichannel distribution system, a switching function to a bypass line is added not only to a terminal unit, but also to an entire system, and reliability of a line is increased by employing a microwave radio link and a public telephone line network.  In a local multichannel distribution system capable  of  providing  services  of  pictures,  data,  and telephones  by highspeed  wireless  transmissions,  when  a failure happens to occur in a wireless line used to connect a base station to set top boxes,  the set top boxes are connected to the public telephone line network as a first bypass line.   When a failure happens to occur in a cable (coaxial cable and/or optical fiber cable:PSTN)  used to connect a head end station with the base station, both the head end station (node station) and the base station are connected to the microwave line as a second bypass line.

Title: Remote audience survey system and method therefor

IPC: H04H1/00
Filed: 1996-01-26
Abstract: An antenna (26) projects a detection zone (28) across a road. A scanning receiver (32) couples to a computer (34). The receiver looks for one FM local oscillator (LO) signal (22) that may be emitted from within the detection zone. If one LO signal is detected, other LO signals that may be detected at the receiver are ignored until the one signal is no longer detectable (90-106). Detected LO signals are ignored if they are detected for less than a minimum duration (100) or if they are detected for greater than a maximum duration. The second of two consecutively detected LO signals is ignored if it occurs within a minimum duration from the previously detected LO signal and exhibits the same frequency as the previously detected LO signal.

Title: A call recording system and method for use with a telephone switch
Inventor: VAN BERKUM PAUL E
IPC: H04M11/00
Filed: 1997-09-18
Abstract: A call recording system and method records telephone calls routed by a telephonic switch 104 to agents located at computer terminals 108. A call information circuit 110 associated with the telephonic switch 104 detects information, such as DNIS via a DNIS circuit 112 and/or information provided by the caller, relating to the telephone calls. The computer terminal 108 includes a recording device 114 which records the telephone calls based on the call information relating to the calls. The recordings of the calls are stored in a storage device 116. To facilitate later replaying a call, a call sequence indicator 118 attaches a call sequence number to a recording of telephone call. Alternatively, or in addition to, a call time indicator 118 attaches a time and day indicator to the recording based on when the call was received. An automatic recorder 122 automatically records specified telephone calls based on the call information. An overwrite circuit 126 overwrites the call recording in the storage device every time period. A period selector 128 permits the agent, or an administrator, to select the length of the time period.
