Abstract: A method of manufacturing a semiconductor device, comprising the steps of sequentially forming a buried region (32) and an epitaxial layer (33) on a major surface of a semiconductor substrate (31), forming a conductive layer (40') along an annular trench (38) extending to the buried region (32), filling the annular trench with an insulating material (41) and forming a functional element in said epitaxial layer (33) surrounded by said buried region (32) and said insulating material (41) within said annular trench. In this method, the step of forming the conductive layer (40') along the annular trench (38) is carried out by the steps of forming an annular trench (38) extending through said buried region (32), and depositing a conductive layer (40') on only a side wall surface of said annular trench (38).

Abstract: A system is disclosed for providing multi-channel transmission of digital and broadband video information in optical fiber communication for local area networks through frequency-division-multiplexing. A plurality of closely spaced optical carrier wave pairs is generated with the optical carrier waves within each optical carrier wave pair having a predetermined separation frequency between one another. Each of the plurality of optical carrier wave pairs is assigned to a predetermined frequency slot and optically combining the plurality of optical carrier wave pairs to provide a multiplexed optical output wave. Advantageously, in addition to direct detection the plurality of optical carrier wave pairs may be detected by opto-electronic heterodyne detection and/or incoherent optical-heterodyne detection to electronically recover the optical carrier wave pairs.

Abstract: An air-cooled block cylinder head adapted for mounting on an open-deck cylinder casing of an internal combustion engine. In order to maintain a tight seal of the cylinder head to the cylinder casing, the combustion chamber floor of the cylinder head is designed to be deflected in a manner that does not adversely affect the sealing of the cylinder head to the cylinder casing. This is achieved by designing the cooling chamber side of the cylinder head floor with a gradually changing floor wall thickness in the area directly above the cylinder combustion chamber. In the preferred designs, the combustion chamber floor is designed to be concave or convex. The cylinder head also includes features for effectively cooling the combustion chamber floor and for isolating the exhaust conduit.

Title: Means for parking read/write heads in a disc drive using the  back-emf of the spindle motor to operate a stepper motor
Inventor: WEVERS WILLIAM E
IPC: G11B20/10
Filed: 1986-11-19
Abstract: Electronic circuitry is provided to position the read/write heads (10) in a designated landing zone when the electrical power is removed from the drive (27). when power is removed from the drive, the stored energy of the rotating spindle motor (27) is used as a source of electrical power and timing pulses to the stepper motor (30) which drives the actuator of the disc drive. The power generated by the spindle motor as it spins down is referred to as "back EMF". A sequencer circuit (50) is provided to couple the power and clock pulses to selected windings of the stepper motor (30) in an order that will cause the stepper motor to rotate in the direction necessary to move the transducer heads (10) to a predetermined park position at the inner diameter of the disc whenever power is removed from the disc drive. Since the location of the heads at power down may not be known, the timing of the pulses in such that a sufficient number of steps will be taken to move the transducer heads to the parking zone within the time allotted even if power down occurred when the heads were at the outermost track. Step pulses will continue to be generated until the back EMF of the spindle motor is insufficient to generate such pulses. After the transducer heads are at the predetermined parking location, any additional steps will cause the actuator to contact a mechanical "inner crash stop" designed to prevent damage to the transducer heads from contact with the clamp which retains the discs.

Abstract: A method and apparatus for improving the per­formance of data compression processes, such as rela­tive address coding, CCITT standard facsimile process­es, and similar two-dimensional image coding processes, by block coding one or more of the vertical mode codes produced by these processes. The performance of data compression processes is improved by representing one or more sequences of vertical mode code words with a single block code word. A reference scan line is pref­erably selected from among a plurality of previous scan lines, for example, the immediately preceding ten scan lines, for two-dimensional image coding. The previous scan line which is most similar to the current scan line to be coded is selected as the reference scan line. The selected reference scan line is then fed with the current scan line to be coded to a two-dimensional data compression coding process so as to yield a first tier of data compression. The image data are preferably checked during the two-dimensional data compression coding process for a predetermined run of a given ver­tical mode code, and a preselected block code is substi­tuted if the predetermined run of the given vertical mode code appears so as to yield a second tier of data compression. Preferably, eleven consecutive vertical offset zero code words are represented by a single block code word. This provides enhanced data compression and reduces the amount of image data stored or trans­mitted and concomitantly lowers the cost for operation of the image data storage or transmission apparatus.

By means of through-­holes (37...42) formed in the reinforcing rings (13) and end rings (14), the compartments communicate with each other so that a temperature-control medium, which is supplied and dis­charged at one end, flows completely about the tank along a meandering path and through a vertex channel (34) which in­cludes the tank fittings (18).

Abstract: A method and apparatus for identifying the class of an operator assistance call in order to reduce the operator work time for serving such a call. A customer dials 0 or dials 0 plus a directory number and is connected to a program controlled operator assistance system or switch (1). The switch initially connects the calling customer to a voice processing unit (14) and prompts the customer to speak a command or key a command code. The command or command code is recognized and used to direct the flow of the control program to selectively defer a connection to an operator position (24). For example, for person-to-person calls, the operator position is only connected after the called customer terminal answers. Advantageously, such a method and apparatus substantially reduces operator work time for broad classes of frequently used operator assistance services.
