Title: Optical reception circuit for ternary apd
Inventor: OGATA TAKAAKI
IPC: H04B10/50
Filed: 1991-10-04
Abstract: PURPOSE:To apply automatic control to the ternary APD so that the multiplication factor is not much decreased because the band width is rapidly reduced when the multiplication factor of the ternary APD is too much decreased. CONSTITUTION:An optical signal to be inputted is converted into an optical current signal by a ternary APD 1, subject to current voltage conversion by a preamplifier circuit 2, amplified by an equalization amplifier circuit 3, a high frequency component in an output signal of the equalization amplifier circuit 3 is extracted by a high pass filter 4 and a peak detection circuit 5 detects a peak level of a high frequency signal. A reverse bias control circuit 6 controls a reverse bias application circuit 7 so that the detected peak signal is less than a set threshold level thereby preventing the multiplication factor M of the ternary APD 1 from being much decreased. Thus, it is not required to make adjustment in matching with each characteristic of the ternary APD, the man-hour is reduced and even when the characteristic of the ternary APD is subject to secular change, since automatic control is always applied, the deterioration in the dynamic range of the optical receiver is not deteriorated.

Filed: 1992-10-22
Abstract: PURPOSE:To reduce the processing time by providing a standard coefficient table in a picture compressor so as to eliminate the need for loading the standard coefficient table from an external storage device and to attain high compression rate in the case of data compression. CONSTITUTION:When standard picture data are compressed, a standard coefficient table is read from an internal ROM 22 through an adder 20 and quantization or decoding is implemented by a computing element 14. Furthermore, in the case of compression for picture data for non-standard application, a difference coefficient table for difference between a coefficient table corresponding to the application and the standard coefficient table is loaded from an external storage device to an internal RAM 12, adds it by the adder 20 and the computing element 14 implements quantization or coding. Thus, the processing time of the standard application is shortened, the compression rate is increased, and the table information quantity is reduced for even the non-standard application and the compression rate is increased.

Title: Graphic output device
Inventor: KUMAZAKI HITOMI
IPC: G06T11/20
Filed: 1990-10-23
Abstract: PURPOSE:To enhance an effect of anti-aliasing process by correcting a state that lateral lines are expressed thinner than vertical lines at the time of outputting from a laser beam printer, etc., by using a filter of long vertical length when dividing a pixel to be used into subpixels, filtering it, and adding them in one pixel to calculate an area rate. CONSTITUTION:If a width ratio of a vertical line to a lateral line is c:1 and a subpixel division of m*m is used, when the vertical length of a filter is x=m(c-1)/2, it is extended by a value obtained by multiplying 2/m by the round-up fraction of the x. The total of one pixel part at the center of the filter is obtained, and the standard value of the filter is set to A. Since the filter has a vertical length of one pixel or more, an image to be filtered by the filter needs (1 + (round-up fraction of x) X 2/m) line, and hence image data of the line is always stored while updating the content. The image data of a plurality of the lines is divided into subpixels, and filtered by a filter having long vertical length to obtain an area rate. If the calculated value is larger than the value A of the filter, the value is replaced by a.

Title: Floor placement type of air conditioner
Inventor: KOZAI TETSUYA
IPC: F24F1/00
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To enable the cleaning work without separating a heat exchanger from a unit so as to shorten the work time, by making the roof plate and rear plate of a cabinet into split structure, and making the under partition plate of the heat exchanger into split structure. SOLUTION: Since the air sucked in by a blower 1 is sent to a heat exchanger, a dirt adheres to the primary side of the heat exchanger 3. The roof plate 5 and rear plate 6 of a cabinet are made in split structure capable of removal by screwing, insertion, or the like. Therefore, the user can draw out the heat exchanger 3 and see the rear side of the heat exchanger without taking off the roof plate 5 and removing a pipe from the heat exchanger 4. Then, the cleaning work of the heat exchanger 3 from above the unit becomes possible by putting a cleaning nozzle 15 into the unit from the topside of the unit. Moreover, since the partition plate 8 under the heat exchanger 3 is made in split structure capable of removal by screwing, insertion, or the like, there is no necessity to remove a blower 1 and a motor 2 at cleaning by taking off this service plate.

Title: Liquid crystal computing element and image processing system using this element
IPC: G02F1/13
Filed: 1991-10-31
Abstract: PURPOSE:To speed up computation and to eliminate the need for alignment by enabling the direct execution of all or a part of the computation of images without via LSIs. CONSTITUTION:Charges are accumulated in an auxiliary capacity C1 only in the point irradiated with light when the element is first irradiated with light having image information from a glass substrate 1 side in the state of impressing a voltage to a source line 7 and a lower electrode 4. The charges accumulated in the auxiliary capacity C1 are partly transferred to a liquid crystal capacity C2 and the image information is stored when the lower electrode 4 and a counter electrode 9 are short circuited. In succession, the charges accumulated in the auxiliary capacity C1 are partly transferred to the liquid crystal capacity C2 when the element is irradiated similarly by the light having another image information separate from the image information and when the lower electrode 4 and the counter electrode 9 are thereafter short circuited in the same manner. The image information by this transfer is then overwritten on the previously transferred and stored information. The above-mentioned computation is just one of examples and the various kinds of the computation by other processing are possible. Further, the continuous processing of the image computation is possible if this liquid crystal computing element and space optical modulator are combined.

Title: Integrated type polarization splitter
Inventor: BERUNTO ZAUERU
IPC: G02B27/28
Filed: 1992-09-30
Abstract: PURPOSE: To make a light splitter have a relatively short constitution length and to impose a low request on it relating to manufacture tolerance by providing a waveguide film and a specified curved rib in a curved rib shape waveguide integrated on a substrate. CONSTITUTION: A plane waveguide film 20 is formed on the surface of the substrate 1, the rib 21 uniformly curved and provided with a two-stage profile is formed on the film 20 and the rib 21 demarcates the curved waveguide 2 along with the film 20. Then, a waveguide mode made incident to the inner surfaces 212 and 215 of the waveguide 2 is diffused over an arc length and then, emitted from the outer surfaces 211 and 214 of the waveguide 2. For a different polarization direction, for instance for TM polarization, since the waveguide 2 is different from a valid refractive index for the polarization direction, detuning is performed. That is, the overcoupling of light between the outer surfaces 214 and 211 of the rib 21 provided with the two-stage profile is not performed.  Thus, when the waveguide 2 is used, the electromagnetic field of the various different polarization directions is separated spatially with a distance.
