Title: Dental x-ray film developing machine
Inventor: TANAKA HIROYUKI
IPC: G03D3/10
Filed: 1988-01-04
Granted: 1991-12-24
Abstract: ABSTRACT        A dental X-ray film developing machine is described.  The machine has plural compartments arranged along a predetermined travelling path of a dental X-ray film to be developed.  A film-mounting member is provided to mount the film detachably thereon.  The film-mounting member is supported pivotally and releasably by a support.  The plural compartments and support are displaceable relative to each other so as to allow the film to travel successively through the compartments.  Owing to these structural features, the dental X-ray film developing machine is simple in structure and small in overall size.  Its manufacturing cost is low.  It requires an installation space reduced significantly compared with conventional dental X-ray film developing machines.

Title: Method for optical communication of information
Inventor: ROCKS MANFRED
IPC: H04B10/64
Filed: 1988-04-07
Granted: 1991-04-09
Abstract: Summary The  invention describes a method for  optical  communi-cation  of information between transmitter and  receiver spatially  separated from each other. The  principle  of heterodyne  reception is utilized. A  non-modulated  op-tical carrier of a laser arranged on the receiving  side is subdivided in a first fibre-optical coupler (KE) into two portions, the transmission path (EMF) and the  local laser  wave (LL). In one branch, a disp]acement of  fre-quency by the amount .DELTA.f takes place. The  non-modulated optical carrier passes through a one-mode fibre (EMF) in direction transmitting side and is modulated there  with an effective signal in a modulator (MOD) (Fig. 1).  This now  modulated  optical signal travels back to  the  re-ceiving side, where it is converted with the local laser wave (LL) into an intermediate frequency band.

Title: Method and apparatus for expanding compressed video data
Inventor: KEITH JOHN M
IPC: H04N7/26
Filed: 1988-11-10
Granted: 1992-06-23
Abstract: RCA 84,946 Abstract A processor which expands a compressed video signal is disclosed.  The compressed video signal applied to the processor is generated by partitioning a video image into segments and then describing how each segment is filled by using a bilinear equation, that is to say, a linear equation which is a function of a horizontal coordinate X and a vertical coordinate Y.  The coefficients of the X and Y coordinates each include integer and fractional parts.  The circuitry develops a table of values from the coefficient of the X coordinate by repeatedly adding the coefficient in an accumulator.  As each sum is produced, the integer part of the sum is stored.  The table of values is developed from the stored integer sums as the difference between alternate sums, where successive alternate pairs of sums are interleaved.  For example, the table would include the difference between the first and third sums followed by the difference between the second and fourth sums, then the third and fifth sums and so on.          The segment is reconstructed by accumulating alternate ones of the table entries in separate adders.  At each stage in the accumulation, the output values of the two adders are two successive pixel values along the horizontal coordinate of the segment.

A device (Figure 4) using this method is also disclosed.
