Title: Method for purifying isoquinoline
Inventor: HOTTA TSUGIO
IPC: C07D217/02
Filed: 1989-06-30
Abstract: PURPOSE:To obtain high-purity isoquinoline, especially highly desulfurized isoquinoline at a high recovery ratio by separating tar-based isoquinoline from coal tar using cupric chloride, converting the resultant isoquinoline into a complex, decomposing the formed complex and carrying out purification. CONSTITUTION:Tar-based isoquinoline, preferably separated form coal tar regulated to >=90% purity by acid extraction and distillation from coal tar and containing quinoline, quinaldine and sulfur compounds is reacted with cupric chloride in a molar amount of >=1/2 based on the isoquinoline predissolved in an alcoholic solvent, such as ethanol, to form a complex. The resultant complex is then decomposed with a basic aqueous solution in an amount of preferably 5-60 times based on the cupric chloride and heat-treated at 60-100 deg.C for 10-60min preferably in or after decomposing the complex to carry out purification. The isoquinoline after decomposing the complex is subsequently extracted into an aromatic hydrocarbon-based solvent to afford the objective high-purity compound.

Title: Double grid reflection mirror antenna system
Inventor: MAKINO SHIGERU
IPC: H01Q15/22
Filed: 1986-07-18
Abstract: PURPOSE:To constitute the titled system inexpensively by making each grid reflection mirror the same in shape in an orthogonal two polarized wave multicoupler antenna and also making its relative position in the parallel movement so as to use only one forming die. CONSTITUTION:The grid reflection mirrors 1a, 1b are formed as the same specular face form and its relative position is in the relation of parallel movement. For example, as to the grid reflection mirrors 1a, 1b whose reflecting face is symmetrical to each other, the two grid reflection mirrors 1a, 1b are not overlapped to each other by moving them within the symmetrical face groups in parallel and the double grid reflection mirror antenna system is constituted symmetrically. Furthermore, they are moved in parallel within a plane orthogonal to a ray along with the central axis of each of primary radiators 2a, 2b, since the aperture of the primary radiators reside on the same plane and the directions of the center axis of the primary radiators 2a, 2b are made equal, the primary radiator 2a for the polarized wave in the direction e1 and the primary radiator 2b for the polarized wave in the direction e2 are easily fixed by a common structure and the alignment of them is also facilitated.

Abstract: PROBLEM TO BE SOLVED: To prevent buckling deformation of an eaves gutter by solar heat, and improve external appearance of the eaves gutter by forming an interval between a front lug holding part and a rear lug holding part shorter than an interval between a front lug and a rear lug. SOLUTION: First of all, fixtures 9 are fixed in a plurality to an outside surface of a building of the eaves edge by penetrating driving-in pieces through fixing holes 9a at constant intervals in the almost same height. Next, a front lug 2 of an eaves gutter A is put on this side, and is held by a lower part of a suspender of the eaves gutter in a condition of being slightly inclined to the building side. A rear lug holding part 7c is pushed upward in a condition where a front lug holding part 6a is fitted to a recessed part of the front lug 2. The front side tip of a front side horizontal piece 22 is brought into contact from below with a projecting part 2b of the front lug 2, and a horizontal piece 7b of the rear lug holding part 7c is brought into contact from below with a rear lug 4; and the eaves edge A is locked on the suspender of the eaves gutter.  Since a rear plate pressing spring 27 presses a rear plate 5 backward, the rear plate 5 does not fall down forward, and a rear lug holding part 7c firmly holds the rear lug 4.

Title: Dome type diaphragm
Inventor: TANAKA SHOJI
IPC: H04R7/12
Filed: 1990-06-28
Abstract: PURPOSE:To increase a high frequency reproduction limit frequency without increase in the weight by truncating a flat spheroid formed from rotation of an ellipse whose major diameter is a multiple of 1.1-1.2 of a minor diameter around the minor diameter at a face perpendicular to the rotation axis. CONSTITUTION:Since the cross sectional shape of a dome is a flat ellipse, a gradient of a dome outer circumference is increased, in addition since the gradient in a dome inner circumference is conversely decreased, the weight of the dome inner circumference is decreased. Since the major diameter is selected to be a multiple of 1.1-2 of the minor diameter, the gradient of the dome inner circumference is not too much decreased. As a result, an event of occurrence of abnormal resonance or the like due to the deterioration in the strength of the dome inner circumference is not caused regardless of the same weight as a conventional spherical dome and the primary high resonance frequency is increased.
