    摘要: A television receiver comprising a first printed circuit board having a helical resonator filter, an adjacent channel trap circuit and an impedance converter circuit for providing a reduced output impedance, the first printed circuit board being secured to the tuner casing, and a second printed circuit board having first and subsequent i-f amplifier stages, the two printed circuit boards being connected to each other, whereby good skirt characteristics can be simply obtained. Also, no overall adjustment is required but the tuner and i-f amplifier may be adjusted separately, thus providing improved serviceability.

    摘要: A single flare tube, and a joint structure of the single flare tube makes a flare of the single flare tube hardly deformed plastically. Additionally, a tensile stress remains lower and is lower when the single flare tube is fastened. A joint structure of the single flare tube coupled with a union includes a single flare tube having a tube and a flare, a flare nut having a thread and a through-hole that receives the tube of the single flare tube, and a union having a thread for coupling with the thread of the flare nut. A width of a narrow inner circumferential groove of a radially outward extending part of the flare is substantially zero and stays substantially zero when the single flare tube is pushed against and coupled with the union by fastening the threads of the flare nut and the union together. Additionally, an internal diameter of the inner circumferential groove preferably is smaller than an external diameter of the tube. Furthermore, a curvature at a radially outer side of an outer corner of the single flare tube (where the tube is connected with the flare) is larger than a curvature at a radially inner side of the outer corner of the single flare tube along a longitudinal cut section of the single flare tube.

    摘要: Provided is technology which can prevent plunger deformation and further stabilize an intraocular lens insertion operation, even when an insertion tube section of an intraocular lens insertion apparatus has been further reduced in terms of the diameter thereof and has been made flatter. The intraocular lens insertion apparatus includes: a tip end region where a plunger comes into contact with an intraocular lens main body and an intraocular lens holding section; and a bar-shaped section extending from the rear end of this tip end region to the rear of the plunger. The bar-shaped section has a fixed thickness in the direction of the optical axis of the intraocular lens, and has an increasing thickness in a portion where the distance from the tip end of the tip end region is equal to or greater than a predetermined distance in a direction perpendicular to the optical axis direction and perpendicular to the plunger advancement direction.

    摘要: A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which different gas fluids are caused to flow so that they are electrochemically reacted in a pair of electrode reacting portions disposed with an electrolyte layer being interposed therebetween. In consequence, the sealed portions provided at the peripheral edges of the gas flow passages deform in accordance with the creep caused in the electrode reacting portions. This enables a balanced, adequate bearing pressure to be kept applied to the electrode reacting portions and the sealed portions, thereby enabling the fuel cell to be operated in an excellent gas sealed state for a long time.

    摘要: A dielectric resonator microwave oscillator in which the gate of a FET is connected to a resonance circuit. An inductor is connected to the drain of the FET, and the output is taken from the source of the FET. This dielectric resonator microwave oscillator has enhanced negative resistance and positively starts the oscillation even when there is a low reflection coefficient of the resonance circuit. Using a circuit which consists of a capacitor and inductor between the source and the output terminal, a further increasing of negative resistance at the gate of the FET is obtained.
