Patent JP-S59229192-A (JP)
Title: Heat exchanger
Inventor: ISHIZAKA TAKESHI
IPC: F28F1/42
Filed: 1984-05-18
Abstract: PURPOSE:To increase a heating surface area and improve the turbulent flow of cooling medium inside of a tube of cooling medium, by providing a spiral groove over the interior wall of cooling medium tube. CONSTITUTION:A spiral groove 2d of a predetermined depth is formed over the interior wall of a cooling medium tube 2. The bevelled angle of this spiral groove 2d relative to the longitudinal length of cooling medium tube is arranged such that the angle alphab of portion which corresponds to a curvature 2a is sufficiently smaller than the angle alphaa of portion which corresponds to a linear portion 2b in a step of forming the spiral groove 2d, that is, prior to the formation of curvature 2a. By making small the bevelled angle alphab of curvature 2a, it becomes possible to make a portion which is less sharp acting to increase the flow resistance of cooling medium, and thereby allowing for the sufficient relaxation in the flow resistance to the cooling medium at the curvature where it is apt to increase, compared to the linear portion.

When the clock B is sent out, it appears on a line l3, and the 1st latch output thetam of the odd-numbered FF is fetched to the 2nd latch of the same FF. Then the clock A' apears on a line l2, and the odd-numbered FFs fetch outputs SID, thetas2- from an input terminal and precedent FFs to their 1st latches. Then, the clock B appears on a line l4, and the latch outputs thetam2, thetam4- of the even-numbered FFs are fetched to their 2nd latches; and the operation is carried on similarly. Thus, the data is shifted.

Title: Reinforced molded product of water-hardening inorganic material
Inventor: MORITA HIROSHI
IPC: C04B41/63
Filed: 1987-04-24
Abstract: PURPOSE:To enable formation of a formed product of excellent water resistance, solvent resistance, acid resistance, alkali resistance and high mechanical strength, by impregnating a formed water-setting inorganic material with an aqueous emulsion having particle size of less than a specific value, cross-linking structure and a specific glass transition point. CONSTITUTION:A formed product of a water-setting inorganic material is impregnated with an emulsion having an average particle size of less than 100nm, cross-linking structure and a glass transition point lower than that calculated by the weight fraction method. In this case, when the particle size of the emulsion exceeds 100nm, the adhesion becomes low, when a coating film is formed, resulting in low impregnation into the inorganic material. In some cases, further the gloss and transparency and smoothness of the coating film become unsatisfactory. Additionally, the aqueous emulsion has cross-linking structure and the coating films formed can meet the required properties. Further, the emulsion has the above-cited glass transition point, and shows good plasticizing effect to lower the lowest film-forming temperature, thus the coating films of desired properties can be readily formed at room temperature.
