Title: Drawn image coding method
Inventor: KISHIMOTO TOMIO
IPC: G06T9/20
Filed: 1981-05-25
Abstract: PURPOSE:To realize coding with high efficiency and without causing an overload, by comparing a differential decision with two threshold values and coding coordinate data with the vector value having the differential value smaller than a certain value as well as with the absolute coordinate value. CONSTITUTION:The coordinates Pi or Pi' is delivered according to the fact whether the enclosed point is the changing point obtained immediately after a pen-up state is changed to a pen-down state. Then the differential between the point where the coding is over and the point enclosed next is calculated in terms of the (x) and (y) directions to obtain DELTAxi=xi-xi-1 and DELTAy1=y1-yi-1. Then the question whether or not these differential values are larger than the prescribed value DELTAm1 is decided. If the differential values are smaller than DELTAm1 both in the (x) and (y) directions, DELTAi or DELTAi' is delivered according to the fact whether the point is equal to the changing point. If not, whether or not the differential value is larger than the threshold value DELTAm2 is decided again. If both differential values are smaller than the threshold values, respectively, the differential vector is divided.

Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To restrain the strain and the shifting of a roll caused by the difference of expansions by forming a casting surface with a copper or copper alloy- made cylindrical tubular roll body having a specific wall thickness and directly connected with one pair of stub shafts. SOLUTION: In a constitution of the copper or copper alloy-made cylindrical tubular roll having 30-200 mm wall thickness, the tubular roll body 20 is fixed between the stub shafts 21, 22, and this peripheral wall is not supported between the stub shafts 21, 22.

The stub shafts do not receive the strain caused by thermal effect and the force in the lateral direction. The compact constitution of a cooling water passage and the constitution having uniform temp. distribution and sufficient mechanical strength can be achieved by using the hollow part in the longitudinal direction of the tubular roll body in order to obtain the cooling water passage and the stub shaft fixed points.

Title: Oxygen dissolving apparatus
Inventor: NISHIDA SOUICHIROU
IPC: B01F1/00
Filed: 1979-06-26
Abstract: PURPOSE: To dissolve oxygen in good efficiency by a method wherein, between an inflow pipe of an oxygen dissolving apparatus and a dissolving tower, an intermediate tower having an intermediate cross sectional area between both of them is provided and mutually connected.  
     CONSTITUTION: An inflow pipe 1 and a dissolving tower 3 are connected through an intermediate tower 2 having an intermediate cross sectional area between that of the inflow pipe 1 and the dissolving tower. In this constitution, an oxygen-containing gas is supplied from a gas supply pipe 5 and released through a gas diffusing device 4 into the dissolving tower 3 as bubbles. Water is introduced from a water inlet pipe 1 through the intermediate tower 2 and flowed downward through the dissolving tower 3. Then, because water flow speed in the intermediate tower 2 is slower than the upward flow speed of large gas bubbles and higher than the speed of fine gas bubbles, said water stream shears said large gas bubbles and disperses them into the dissolving tower 3 as well as disperses throughout the dissolving tower 3. Therefore, a gas-liquid contact area and time are increased and the dissolving efficiency of oxygen is enhanced.
