Title: Method for matching impedance of coaxial connector
Inventor: YAMAZAKI SHUJI
IPC: H01R13/646
Filed: 1993-12-28
Abstract: PURPOSE:To facilitate the matching of characteristic impedance of a coaxial connector. CONSTITUTION:In a coaxial connector formed of an external conductor 3, an insulating material 2 and an internal conductor, a range of the opposite characteristic impedance is set near a range, in which the characteristic impedance of the coaxial connector is displaced from the characteristic impedance of a transmitting system. Characteristic impedance of the coaxial connector can thereby approach the characteristic impedance of the transmitting system to obtain the matching of impedance.

Title: Wet-type recovery of iron chloride powder
Inventor: KASAI KATSUJI
IPC: C01G49/10
Filed: 1994-12-29
Abstract: PURPOSE: To prevent the formation of sediment in a dissolution tank and the flying of iron chloride powder out of the dissolution tank in a wet-type recovery of the iron chloride powder such as FeCl2 powder. CONSTITUTION: Iron chloride powder is transported to a dissolution tank by the flow of a non-oxidizing gas and the non-oxidizing gas is bubbled in the tank to dissolve the iron chlorine powder in a liquid. The use of the non- oxidizing gas as a carrier gas enables the suppression of hydration to the iron chloride powder during transportation, the reduction of the amount of the dissolved oxygen in the liquid in the tank, the efficient deaeration of the oxygen dissolved in the liquid by bubbling, and the extension of the contact time of the liquid with the iron chloride powder. These effects suppress the formation of iron sediment in the liquid.

Abstract: PURPOSE:To detect the angle of rotation of a rotary shaft over an entire circumference by setting the area of the parts where a projection part for detection and a magnetic circuit constitution part in each group are faced with each other so that the area is increased or decreased in specific relation as the rotary shaft is rotated. CONSTITUTION:A rotational angle detection part 5a detects the angle theta of rotation of the rotary shaft 1 by projection parts 9a1 and 9a2 from zero to piand by projection parts 9a3 and 9a4 from pi to 2pi. When the angle theta, however, is almost zero, pi, or 2pi, the facing area between a magnetic body piece 3 and the projection parts 9a1 - 9a4 is varied greatly, so the value of a detected voltage is also varied and a discontinuous point is generated in the detection area. For the purpose, the detection projection parts 9b1 - 9b4 of a rotational angle detection part 5b are disposed by shifting from the projection parts 9a1 - 9a4 by an angle pi/2 in terms of rotation, so a rotational angle area which becomes the detection discontinuous point of the detection part 5a can be covered. The angle theta of rotation of the rotary shaft 1 can accurately be detected over the entire circumference.
