Title: Picture data compressor
Inventor: TOYOMURA YUJI
IPC: H03M7/30
Filed: 1989-09-11
Abstract: PURPOSE:To improve the compression rate and to suppress the deterioration in a restored picture by quantizing a difference between the representative value of blocks each split to a prescribed number of picture elements and a predicted data to compress a picture data. CONSTITUTION:For example, a luminance component Y is subject to block coding by a 2 mean value method in block size of 2X2 at a block coder 55 and the result is converted into large and small luminance component representative data and a bit map data. Then data selectors 63, 64 are used to select a group with a larger value in two representative data obtained by the 2 mean value method. A data selector 91 outputs an actual mean value of a group having a large block value predicted this time. The said data and a data from a prediction section 90 are given to a differential arithmetic section 55, which outputs a difference of both the data. A quantization section 66 applies quantization converting a data from the differential arithmetic section 55 into a data of a prescribed bit number.

Filed: 1983-12-13
Abstract: PURPOSE:To enable characters to be printed at high speed and with high accuracy, by fitting a driving spring member perpendicularly to an armature. CONSTITUTION:One end of a driving perpendicular spring member 6is fitted to a spring holder 7, and the other end is fitted to the armature 8 fitted with a printing wire movable part (a printing wire 4, a backbone 3) so that the bending direction of the spring member 6 is substantially perpendicular to the moving direction of the armature 8. Since the armature 6 is fitted directly to the spring member 6, the wieght W of the armature 8 can be located in proximity to the spring member 6, and a length l5 can be minimized as compared with a length l1. Accordingly, it can be contrived to enhance printing speed without breaking an ink ribbon or a paper.

Title: Solid-state image pickup television camera
Inventor: NOGA TAKEHIRO
IPC: H04N5/372
Filed: 1989-09-11
Abstract: PURPOSE:To prevent inconvenience that a video signal is lost from a telecamera by eliminating a transfer gate pulse from another transfer gate pulse fed to a solid-state image pickup element when a strobo pulse is in a specific timing. CONSTITUTION:In the special case that a timing pulse ST lighting a strobo 2 exists within a consecutive time of vertical synchronizing signal VD of a CCD(Charge Coupled Device) telecamera 4 and a transfer gate pulse TG near the trailing edge of the vertical synchronizing signal VD, the transfer gate pulse is eliminated from the transfer gate pulse TG supplied to the CCD image pickup element so as to avoid the signal charge stored so far in the photodiode of the CCD image pickup element from being transferred. The signal charge has been transferred in a conventional telecamera and outputted as a video signal from the telecamera, but when the strobo pulse ST was in the special timing in the picture processing unit, since the video signal just after the timing was not stored, it resulted in inconvenience of losing the video signal finally. Thus, the inconvenience is prevented.

Abstract: PURPOSE:To prevent wirings from disconnection without lowering element integration by a method wherein the surface is subjected to etching of a lower interconnection layer led out of a window when a layer-connecting window is provided in an insulating film between multilayer interconnection layers. CONSTITUTION:On a semiconductor substrate 1 wherein the construction of elements and the provision of a window for connection of wirings have been completed, a lower interconnection layer 2 is formed and, thereon, an inter-layer insulating film 3 is formed. Next, a photoresist 4 is formed and serves as a mask in a selective etching process for the creation of a layer-connecting window 5. After removal of the photoresist 4, the surface, exposed in the window 5, of the lower interconnection layer 2 is subjected to etching. This widens a gap 7 between the inter-layer insulating film 3 and an interconnection layer 2a, created when there is a displacement between the window 5 and an upper interconnection layer 6. A process follows wherein the upper interconnection layer 6 is formed on the interconnection layer 2a lower in the window 5, the semiconductor substrate 1, and insulating film 3. A step in the interconnection 6 at the gap 7 is covered better in this way, which ensures the prevention of a step-caused disconnection.

Abstract: PURPOSE:To obtain an excellent muffling effect while keeping the compactification and increase in output by forming the outside of an acoustic material installed to the muffler cylinder inner surface of glass wool and the inside of brass wool. CONSTITUTION:An inner cylinder 3 having a plurality of ports formed thereon by using a stainless mesh or punching metal is held within an outer cylinder 2 by end plates 4a, 4b. An acoustic material 5 is installed to the inside of the outer cylinder 2.
