Title: Picture signal processing unit
Inventor: MARUYAMA YUJI
IPC: H04N1/405
Filed: 1987-10-23
Abstract: PURPOSE:To improve the quality of a line picture or character picture by calculating a difference of density level between a preceding picture element and a noted picture element and bringing forcibly the binarized level to a black or a white level depending on the quantity between the difference signal and the threshold value. CONSTITUTION:A differential operation means 102 consists of a register and a differential arithmetic unit, calculates a difference between the density level of the preceding picture element and the density level of the noted picture element and outputs a difference signal Bxy to an output discrimination means 103. The means 103 consists of a comparator receiving positive/negative threshold values and a AND and an OR gate, and receives the signal Bxy and the binary level Pxy from the binarizing means 100. When the signal Bxy is larger than the positive threshold value, the level Pxy is forcibly to the black level and when the signal is larger than the negative threshold value, the white level is obtained forcibly. When the signal Bxy is smaller than the positive/negative threshold value, the level Pxy is outputted as it is as the output picture Oxy. Thus, the quality of the line picture and character picture is improved.

Title: Grid type conveying device
Inventor: KATAOKA NOBORU
IPC: B65G17/06
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To simplify work and to give consideration to workers by composing a conveying device of a grid-like pallet provided in an intermittent rotary endless carrying section, a connecting body, a connected body provided in an always rotary endless carrying section for connecting the same and a stopper for stopping the pallet. SOLUTION: An always rotary type chain is always rotated at a constant speed by a driving device. Accordingly, while the magnet of a grid-like pallet is magnetically fixed to a steel plate provided in the chain element of the always rotary type chain, an intermittent rotary type chain and the grid-like pallet are traveled in the same direction and at the same speed integrally with the always rotary type chain. These are almost simultaneously stopped by the stopping of the pallet with a stopping means. When a stopper is operated during pallet traveling, the pallet is forcibly stopped and the magnet provided in the pallet is always separated from the steel plate of the always rotary type chain, and thus only the always rotary type chain is traveled. This stop state is always held during the operation of the stopper.
