Filed: 1983-03-24
Abstract: PURPOSE:To provide an excellent discharging characteristic, by using a positive electrode active material made from water-washed or neutralized electrolytic manganese dioxide mixed and treated with water solution of manganic salt or the like. CONSTITUTION:Electrolytic manganese dioxide washed in water or neutralized with an alkaline water solution of sodium or ammonia is mixed and treated with a solution of manganic salt in water or a mixture of manganese hydroxide and water, and thus the positive electrode active material is provided. As the manganic salt, chloride, nitrate, or sulfate, for example, is usable. As the result, protons, sodium ions, or ammonium ions on the surface of the manganese dioxide are replaced with bivalent manganese ions, whereby the intersection of the two straight lines represented the relationship between the potential on the manganese dioxide and the PH value is shifted toward the acidic side and therefore the potential variation per PH is kept low in a wider range of PH values. Thus, the excellent discharging characteristic can be provided, that is, the voltage drop of the cell during its discharging is suppressed and, in particular, the increase in the impedance in and after the middle period of the discharging is made practically negligible.

Title: Selective call receiver
Inventor: ISHIGURO SATOMI
IPC: H04W84/02
Filed: 1991-02-25
Abstract: PURPOSE:To easily change a reception frequency without increasing a current consumption much. CONSTITUTION:A crystal vibrator 22 is connected to a 1st local oscillation circuit 20 via a socket 21 and replaced with each other. On the other hand, since a decoding control section 30 of an antenna tuning circuit 3 sets any of control signal lines 35-37 to a high level based on the information written in a storage section 31 corresponding to the reception frequency, any of transistors(TRs) 9-11 connecting to the control signal lines set to a high level is turned on. Since only a capacitor among capacitors 5-7 connecting to the TRs 9-11 set to the ON state is connected in parallel with a trimmer capacitor 2, the reception frequency is easily changed without need of fine-adjustment by setting the capacitors 5-7 to a capacitance minimizing the transmission loss in response to the reception frequency band.

Abstract: PURPOSE:To produce the title shift fiber with a low transmission loss by providing the inside core of Ge-SiO2, the outside core of F-SiO2, and the clad of F-SiO2 to form a stepped refractive index distribution. CONSTITUTION:Fine glass particles are deposited on the tip of a starting quartz rod 3.2 while rotating the rod to form the porous glass body 3.3 for the inside core of Ge2SiO2, F is added into the SiO2 by the same method to form the porous glass body 4.2 for the outside core, a hole is then bored at the center, and the inside glass body 4.1 is inserted into the hole, heated, and contracted. The SiO2 similarly formed is added with F, and the composite of the inside and outside cores is inserted into the center hole of the clad, heated, and contracted to a specified size. Since F is added in this way, the loss deteriorating factor in the UV region is reduced, and the transmission loss of the stepped dispersion-shift fiber can be lowered.

Filed: 1985-03-15
Abstract: PURPOSE:To increase the permeability along a magnetic circuit and to restrain the eddy-current loss in a vertical plane by making a magnetic field in the same shape with the magnetic circuit of an electric apparatus in which a magnetic material is used. CONSTITUTION:For example, soft magnetic powder such as iron powder, etc. is injection-molded using a pellet previously kneaded with nylon, etc. When plastic is melted in a cavity 3 and a magnetic field is formed in the cavity 3 applying a current in a coil 4, the soft magnetic powder in the plastic is orientated in the direction of a magnetic path and fixed in the plastic in the orientated state by cooling. A coil 4 with the core material manufactured in this way for a transformer and a primary winding 5 constitute a magnetic circuit which has the same shape for each of the cavity 3 and a core 7. This reduces the magnetic reluctance in the direction of a magnetic path in the core 7 of the transformer and can restrain the eddy-current loss generated in a vertical plane.
