Hybrid FRP shell by the carbon + Tekisaryumu

Vibration mode becomes the single is a single material, the inherent nature of the material will be reflected. In Oyaide electricity, based on the experience obtained in INS-CF, adopt state-of-the-art material "Tekisaryumu" over both sides of the front and back of the head shell. This state-of-the-art material was aluminum metallization coating for high-density glass fiber, high density than carbon, has the qualities that somewhat soft (density: Tekisaryumu 2.55g / cm3, carbon fiber 1.84g / cm3 Young's modulus : Tekisaryumu 69GPa, carbon fiber 392GPa). By hybrid this Tekisaryumu to dry carbon cloth, it has to disperse the vibration mode of a single carbon material. 1K plain weave and has been Tekisaryumu is, not only the terms of performance, has given a beauty shining in silvery white on the head shell.

Inner layer sandwiched between the Tekisaryumu is composed of a carbon cloth over 13 layers. The carbon cloth material is also used in the Boeing new aircraft, manufactured by Toray Industries high strength employs a carbon fiber "T700".

In addition, without the uniform thickness of the carbon cloth layers, by slightly changing, we have to maximize the damping effect of vibration. CFRP of these Tekisaryumu and carbon cloth with high toughness epoxy resin.

Molding of the shell as well as the HS-CF, adopt an integrated angle molded by a mold. This results in the case of the L-shaped two plate members joined at right angles adhesive, and avoiding detachment of disturbance or plate of the vibration moment. Molded product is then, one by one cutting process is performed by the CNC machining, it will be completed as a part. As a result, high-rigidity, equipped with a high toughness, even while quickly damping vibrations, does not impair the atmosphere of music, it has succeeded in the development of the head shell portion having advanced performance.

The socket part

Socket portion to be fitted to the tone arm is constructed by press-fitting the 30% glass filler mixed PBT resin in an aluminum coupling. The resin is a high strength resin to be classified as engineering plastics, contributing to enhanced vibration damping and strength of the socket portion. Contact pin was gold-plated to brass. The tone arm contact portion and the lead wire contact part, adopted a brass material were plated rhodium plating. We are working to improve the high-frequency characteristics and durability.

Finger hook

Also to finger rest, there is a commitment Oyaide electrical unique. In the "HS-TF", adopted a finger hook which has been subjected to chic satin chrome plating on aluminum material. By disposed on the front side of the head shell portion, Smoother operability of the arm. Finger hook portion, which is designed with exquisite Earl, the fingertips invite the arm on the record board, it gives a pleasant feel, high-quality.

Shell lead wire (HSR-CU Special Edition)

PCOCC-A a (unidirectional crystal oxygen-free copper wire) adopted the conductor, on the basis of the "HSR-CU," which was released in the spring of 2009, and modify to a dedicated "HS-TF", "HSR-CU Special Edition "a standard feature. Wire part is similar to the "HSR-CU". That is, rather than twisting the entire wire, the wire of 0.08mm to geometrically stable 1 unit twenty concentric twist structure, further grouped into one of three units.

Adopt the PFA with the electrical characteristics unparalleled among the insulating material on the exterior. Moreover, the thickness of the insulating body achieve phenomenal thin as 0.18mm. These fuselage structure, by an insulator, reducing the transmission loss before stoic. Terminal tip portion, a phosphor bronze as the base material, in order to improve the prevention and conductivity and durability oxidation of aging, has undergone a "HSR-CU Special Edition" unique rhodium plating.

In the rhodium plating is sound quality, contributing to a sharp music playback capability to more prominent ones of "HS-TF".By the "HSR-CU Special Edition", the signal captured from the face of a board, will be communicated to the tone arm without leaving the energetic.
