Patent JP-H06197043-A (JP)
Title: High frequency switch
Inventor: TSURU TERUHISA
IPC: H04B1/44
Filed: 1992-12-26
Abstract: PURPOSE:To reduce an insertion loss at transmission and to improve the isola tion at reception by employing a 2nd diode with a small ON-impedance and connecting its cathode to ground via a parallel circuit comprising a capacitor and a resistor. CONSTITUTION:When the high frequency switch 10 is used to make transmission, a positive voltage is impressed to a control terminal 22. The voltage is impressed to a 1st diode 14 and a 2nd diode 30 as a forward bias voltage respectively to turn on the diodes 14, 30. Thus, a transmission signal from a transmission circuit TX is sent from an antenna ANT. In this case, an ON-impedance of the 2nd diode 30 is as small as 1ohm and a 2nd strip line 26 is connected to ground via the 2nd diode 30 and resonated and the impedance is almost infinite. Thus, the transmission signal is not almost sent to a reception circuit RX and the insertion loss is reduced. On the other hand, when the switch 10 is used to make reception, the diodes 14, 30 are nonconductive and the reception signal is not almost sent to the circuit TX.

Title: Method for removing halogen radical in copper halide solution
Inventor: INOKO MASANORI
IPC: C23F1/46
Filed: 1991-12-27
Abstract: PURPOSE:To remove a halogen radical from copper halide solution. CONSTITUTION:A tube pump 2 and an anion-exchange resin tower 3 are arranged in a line 1 in this order from the upstream side and the anion-exchange resin tower 3 is packed with anion-exchange resin 4. Copper halide solution is made to flow in the anion-exchange resin tower 4 through the line 1 by the tube pump 2 and then solvent is similarly made to flow in and recovered after it leaves the tower. When the copper halide solution flows in the tower, copper in the copper halide solution becomes anions to adsorb them by an anion-exchange resin layer 4. On the other hand, free halogen flows out on the downstream side of the anion-exchange resin layer 4. Next, when solvent flow in the tower, the adsorbed copper becomes cations to eliminate them from the anion-exchange resin layer 4, causing them to be included in the solvent for recovery. Therefore, the total amount of halogen radicals in the recovered solution is decreased compared with that of halogen radicals in the original copper halide solution.

Title: Screw-feeding motor
Inventor: MATSUBARA FUMIHIRO
IPC: H02K5/173
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a screw-feeding motor which can use a screw shaft with a small diameter and realize cost reduction. SOLUTION: A screw-feeding motor has a screw shaft 31, whose base end side is pushed into a cylindrical hole 30a of a PM-type inner rotor 30 and which has a male screw part 31a over its entire length. The shaft 31 is a rolled screw shaft, obtained by cutting a rolled screw rod to a prescribed length. The PM- type inner rotor 30 is a bottomed cylindrical unit, which has a thrust bearing mechanism 40 regulating the rotating center of the outer surface of its bottom 30b and a ring plate 50 which elastically biases the PM-type inner rotor 30 consistently via the thrust bearing mechanism 40 in the axial direction. Since it is not necessary to form a ball receptacle hole in the end surface of the screw shaft itself by cutting machinning, the cost reduction can be realized.  Furthermore, since a screw shaft with a small diameter which is not suitable for cutting machinning can be employed, this contributes to reduction in size of the motor.
