It is a subject to provide a method for manufacturing a tire rubber member and a pneumatic tire using the same capable of improving productivity and of accurately finishing sectional shapes. The method includes: a step of fixedly attaching winding start points 8As, 8Bs of a first rubber strip 8A and a second rubber strip 8B at positions located further inside in a width direction than respective sides e1, e2 of a rubber member R; a first winding step of forming a first layer 10 by spirally winding the first rubber strip 8A towards the one side e1 and the second rubber strip 8B towards the other side e2 up to the respective sides e1, e2; a second winding step of respectively turning the first rubber strip 8A up at the one side e1 and the second rubber strip 8B at the other side e2 so as to successively form a second layer 11 outside of the first layer 10; and a step of fixedly attaching a winding end point 8Af of the first rubber strip and a winding end point 8f of the second rubber strip to positions further inside in the width direction than the respective sides e1, e2.

The invention can reduce a step between rubber strips even in the case that the rubber strip is made thick, and inhibits a reduction of uniformity and tire quality, a deterioration of a tire outer appearance, and the like. A rubber strip (10) may be scalene triangular shape, a trapezoidal shape or a parallelogram shape having has a bottom line (11) forming a strip width (W), a first diagonal line (12) extending from one end of the bottom line (11) and a second diagonal line (13) extending from the other end (P2) of the bottom line (11), a length (L0) of the bottom line is set to 5 to 50 mm, and a thickness (T) thereof is set to 0.2 to 5.0 mm.

An LC resonant circuit of an oscillator includes a parallel circuit of an inductor, a first fine adjustable capacitor and a first capacitor bank, and a series circuit of a second fine adjustable capacitor and a second capacitor bank. A frequency conversion gain of the oscillator is the sum of a frequency conversion gain of the oscillator based upon the first fine adjustable capacitor which decreases according to increase of a capacitance value of the capacitor bank and a frequency conversion gain based upon the second fine adjustable capacitor which increases according to increase of a capacitance value of the second capacitor bank. Accordingly, an LC resonant circuit for an oscillator with reduced fluctuation of a frequency conversion gain, and an oscillator and a data processing equipment using the same are provided.

The present invention provides a pharmaceutical composition for treating chronic hepatitis C characterized by comprising at least one active ingredient selected from the group consisting of IL-15, myeloid dendritic cell maturation stimulators (for example, CpG oligo deoxynucleotide, GM-CSF, IL-4, LPS, CD40L, polyI:C, TNF-a and IFN-?) and lectin-binding substances (for example, mannose carbohydrate, fucose carbohydrate and anti-lectin antibody); and a method of treating chronic hepatitis C by using such active ingredient(s). In the above pharmaceutical composition and therapeutic method, it is possible to use INF-a together with these active ingredients.
摘要:
A pneumatic tire comprises a carcass reaching a bead core of a bead portion from a tread portion via a side wall portion; a side wall rubber arranged in an outer side of said carcass and forming an outer side surface of said side wall portion; and a clinch rubber for preventing a rim displacement connected to a lower end of the side wall rubber and forming an outer side surface of said bead portion. The sidewall rubber and the clinch rubber are constituted by a strip wind body formed by winding and overlapping a side wall rubber strip and a clinch rubber strip in a circumferential direction and spirally, and the respective rubber strips are wound in the same direction from the bead portion side toward the tread portion side.

The present invention provides an ameliorant for enhancing the therapeutic effect of IFN-&agr; on hepatitis C; a therapeutic composition for the treatment of hepatitis C which comprises IFN-&agr; and IFN-&ggr; as active ingredients and further contains a pharmaceutically acceptable carrier; a kit for the treatment of hepatitis C which comprises an IFN-&agr; preparation and an IFN-&ggr; preparation; and a therapeutic method for the treatment of hepatitis C which comprises administering IFN-&agr; and IFN-&ggr; to a subject at the same time or administering IFN-&ggr; before the administration of IFN-&agr;. The present invention is capable of making the patient continuously HCV-RNA negative and is extremely useful in the treatment of chronic hepatitis C which is intractable with, IFN-&agr; and conventionally difficult to remedy.
摘要:
A casting method and apparatus using a resin core wherein a portion of a wall of the resin core that receives a greater heat and/or load than other portions of the wall of the resin core, is increased in thickness. As a result, even if the resin core receives more heat and/or load in places, a local deformation or breakage of the resin core is effectively prevented.
摘要:
A casting method is disclosed in which a resin core is fabricated by using a resin which maintains a mechanical strength satisfying a shape accuracy required for a cast product until solidification of molten metal in contact with the core and is softened when heated beyond the core temperature at which the molten metal in contact with the core was solidified. The removal of the resin core from the cast product after the cast product containing the core from a die, includes a step of forcedly cooling the cast product containing the core down to a predetermined temperature at which the resin core can be removed from the cast product without being broken apart by pulling one of its ends, and a step of withdrawing the core at the predetermined temperature from the cast product having been forcedly cooled down. It is thus possible to cool the core down to a predetermined temperature suited for the withdrawal and preclude the inconvenience that the core being pulled is broken apart.
摘要:
DC power is supplied to an induction motor for a compressor by switching ON/OFF in response to a modulated voltage waveform obtained from modulating waves which are used for generating AC power for energizing an induction motor and a carrier wave according to PWM theory. The compressor has a compressing element rotated by the induction motor, and the modulating wave is corrected according to a rotational angle of the compressing element. A sine wave having the same frequency as the modulating wave is added to the modulating wave, and a phase of the sine wave is controlled so that a maximum value of the sine wave corresponds to the compression stage of the compressing element. Thus, a rotation speed of the compressing element is constant in a suction stage and a compression stage.
