Title: Antenna coil
Inventor: MORIFUJI MOTOYOSHI
IPC: H01Q11/08
Filed: 1990-04-27
Abstract: PURPOSE:To prevent the characteristics of an antenna coil from being deteriorated due to a secular change by fixing a spiral coil whose one end is open to a bobbin molded with a resin material, linearly stretching linearly the other end of the coil from the lower end of a projection part formed on the center part of the lower side of the bobbin and divided in the peripheral direction at its head, and inserting the projection part into a waveguide to insert and fix the other end of the coil. CONSTITUTION:The spiral coil 101 whose one end is opened is fixed to the bobbin 104 molded with a resin material such as polyethylene, the other end of the coil 101 is linearly stretched out from the lower end of the projection part 108 formed on the center part of the lower side of the bobbin 104 and divided in the peripheral direction at its head and the projection part 108 is inserted into the waveguide 202 to insert and fix the other end of the coil 101 into/on the waveguide 202 and obtain the electromagnetic coupling of both the elements. For instance, the coil 101 is pressed and fixed into/on a leading groove 105 whose inside is slightly narrower than the diameter of the coil 101 and the antenna coil is inserted and fixed into a hole 201 formed on the upper face 202a of the waveguide 202 by utilizing the projection part 108 formed on the lower face of the bobbin 104. Consequently, no secular change is generated in respective sizes of respective parts of the antenna and the electric characteristics can be prevented from being deteriorated.

Title: Recovering method for noble metal
Inventor: TANAKA YOSHINOBU
IPC: B01J41/04
Filed: 1985-05-23
Abstract: PURPOSE:To allow a noble metal contained in a dilute solution to be adsorbed in high yield and to recover it by passing the dilute solution of the noble metal through an ion exchange resin layer ascendingly from the bottom toward the top. CONSTITUTION:The dilute noble metal-containing solution containing Au in a concentration of 50mg/l is passed through the layer of strong-basic anion exchange resin grains of 0.3-0.5mm diameter ascendingly from the bottom. The slight amount of Au in the solution is adsorbed successively from the bottom of the ion exchange grain layer. The ion exchange resin grains increased in weight by adsorption of Au are allowed to fall one after another, to which new ion exchange resin grains are supplied from the upper part. In this way, the Au-containing solution is continually passed through the layer of ion exchange resin grains low in adsorbed Au content from the bottom toward the top, so that Au can be adsorbed by the ion exchange resin grains in high yield with high adsorptivity. Then the ion exchange resin which has adsorbed Au to the full is incinerated and the incineration residue is dissolved in aque regia, which is reduced to recover Au.

IPC: G02F1/1339
Filed: 1990-04-26
Abstract: PURPOSE:To obtain an image which has a high contrast and high picture quality by using spacers which are nearly spherical on the whole, and absorb or scatter incident light as spacers of a liquid crystal cell.
