Title: Slotted type deflection yoke core and its manufacture
Inventor: ITAGAKI KAZUYA
IPC: H01F3/08
Filed: 1988-09-14
Abstract: PURPOSE:To lessen the number of burrs so as to attempt the facilitation of grinding the burrs by forming each projecting part located on the side of a large diameter-end part, into a chamfered shape. CONSTITUTION:A slotted core 1 made up of a roughly cylindrical body consisting of a small diameter-end part 2 and a large diameter-end part 3 provided respectively at both ends thereof, is formed with recessed parts 5 and projecting parts 6, which constitute a region of winding along the entire circumference of the inner wall surface 4 of the body. Each projecting part 6 is formed at tits end section 7 on the side of the large diameter-end part 3, into a chamfered shape by an inclined surface 7a and a horizontal plane 7b, turning to the inner wall surface 4 from the outer wall end surface 8a, while the outer wall surface 8 of the body is formed with the outer wall end surface 8a and a curved surface 8b. The projecting part 6 located on the side of the large diameter-end part 3 is thus formed into a chamfered shape. the number of sections suffering burrs is therefore decreased while simplifying the shape of any place having burrs, so that the time required for grinding the burrs may be shortened.

Filed: 1985-10-17
Abstract: PURPOSE:To suppress the generation of hydrogen by applying paste, which is composed mainly of one kind of cadmium oxide or cadmium hydroxide or metallic cadmium and includes antimony oxide or antimony hydroxide, to a conductive core body. CONSTITUTION:Antimony oxide such as antimony trioxide or tetraoxide or the like, or antimony hydroxide reacts with alkali, thereby producing highly- reductive antimonite such as potassium antimonite. Therefore, the antimonite is produced in a cadmium anode, to which active material paste including these materials as mentioned above is applied, by the injection of alkali electrolytic solution at the time of fabricating a battery.

Title: Semiconductor amplifier circuit
Inventor: HIRAKATA NOBUYUKI
IPC: H03F3/45
Filed: 1990-09-03
Abstract: PURPOSE:To compensate a current change due to a drain conductance and to prevent the gain from reducing by providing a load transistor(TR) and a feedback TR between 1st and 2nd drive TRs. CONSTITUTION:The amplifier circuit is provided with a load TR 19 whose source connects to a drain of a 1st drive TR 12 and a feedback TR 18 whose source connects to a drain of a 2nd drive TR 11 and whose gate connects to a source of the load TR 19. Thus, when a differential input signal is impressed to input terminals 15,16, a current signal of the TR 12 is converted into a voltage signal via the TR 19 and the signal is fed back to the TR 11 via the TR 18. Then the feedback signal acts as compensating a current change by the drain conductance of the current signal supplied to a constant current source 13 from the TR 12 according to the drain conductance of the TR 11. Thus, even when the drain conductance is increased, the gain is not reduced and the high speed and high gain amplifier circuit is realized.
