A headrest moving mechanism includes linking members that links a support portion and a headrest base portion to each other; and elongated holes formed in the headrest base portion. The elongated holes slidably receive a connection shaft provided to the support portion, thereby determining a postural position of the support portion. The elongated holes are shaped so as to move the support portion forwardly and upwardly with respect to the headrest base portion from an initial position in a time before the vehicle back-side collision happens to a collision preparatory position as the linking members are rotated.

A lead frame at least provides a semiconductor-element-mounting portion, plural leads and plural auxiliary leads. The auxiliary leads are arranged to be associated with plural leads, while a tie bar is provided and connected among the leads. According to a method of making the lead frame, an IC-chip mounting process, a wire-bonding process, a sealing process, a resin-cutting process and a dambar-cutting process are sequentially effected on the lead frame. After effecting the dambar-cutting process, a thin-plating process is effected so as to form a thin-plated layer, approximately having a thickness of 5 .mu.m to 15 .mu.m, on the leads. Then, the leads are bent by a predetermined bending process. Thereafter, a thick-plating process is effected so as to form an uniform thick-plated layer, approximately having a thickness of 15 .mu.m to 100 .mu.m, on the leads. After effecting the thick-plating process, a trimming process is effected on the leads. Incidentally, the thin-plating process can be effected after the bending process and before the thick-plating process.

In construction of a magnetic encoder used for detection of displacement of a mobile body, a circular magnetized pattern is formed on one longitudinal end face of a magnetic rotary spindle mechanically coupled to the mobile body, and a magnetic sensor faces the magnetized pattern with a prescribed gap. Direct formation of the magnetized pattern on the rotary spindle excludes production errors caused by the conventional coupling process and end-face magnetization assures significant compactness of the entire construction.

In construction of a golf club head having a fiber reinforced plastic shell, the neck section of the shell provides the first hold and an inward bulge on the sole side section of the shell provides the second hold, both for the club shaft so that presence of a dual hold joint structure enables effectual energy transmission at hitting balls and reliably prevents accidental separation of the club head from the club shaft.

One object of the present invention is to provide a production method of a steering wheel in which divided bodies are securely integrated into a single unit without using adhesive. In order to achieve the object, the present invention provides a production method of a steering wheel comprising the steps of: a) providing a plurality of divided bodies 6, each of which comprises a surface material 3 and a plastic layer 4 provided on the inside of said surface material 3; b) forming an outer shell 2 by integrally welding said plastic layers 4 of said divided bodies 6; c) providing a core metal 1 to be arranged in said outer shell 2; and d) filling plastic between said outer shell 2 and said core metal 1.

An electroplating apparatus carries out an electroplating on a work by using an insoluble anode for keeping the electrolyte clean, and, thereafter, makes up ionized metal into the electrolyte by respectively connecting a soluble anode and the insoluble anode with a positive electrode and a negative electrode, thereby preventing an operator from the make-up work.

In construction of a peripheral-magnetization type magnetic encoder having a rotary spindle and a magnetic head, a resin housing is formed by insert moulding so as to embrace the spindle leaving a slight tubular clearance to allow free axial rotation of the spindle, thereby providing direct, simple and stable support to the rotary spindle for enhanced precision in direction.

A magnetoresistive detection head for detecting relative displacement of a magnetic recording medium relative to the detection head includes two sets of magnetoresistive elements which change their respective resistances in response to changes in the intensity of a magnetic field generated by the magnetic recording medium during the relative displacement. The magnetoresistive elements are overlapped and spaced relative to each other by a specified space lag in the direction of the relative displacement. One set of magnetoresistive elements produce a sine output and the other a cosine output. The overlapping and precise spacing of the elements aligns the phases of the signal envelopes of the sine and cosine outputs, reducing reading errors when physical warps appear on the magnetic recording medium.

A wood-type golf club head containing a fiber reinforced plastic outer shell formed by heat pressing in a mould, around an intermediate shell. A solid center core is formed inside the intermediate shell by injection of foam synthetic resin for reduced generation of harsh and keen noises at hitting balls, ideal transmission of striking energy to balls and high durability against shocks by hitting balls. The elastic modulus of the outer shell material is greater than that of the intermediate shell material. The buckling strength of the intermediate shell material is greater than that of the foam resin core material.

An operation cable has an operational structure in which an inner member inserted into a tubular outer member is pulled from a lower end side thereof. The operation cable having a double layer structure is axially connected to a double layer cable that is constructed from a stay of a headrest and a push rod inserted into the tubular stay. In particular, the stay is inserted into a support positioned on an upper portion of the seat back, a lower end of the stay and an upper end of the inner member are axially connected to each other, so that a lower end of the push rod in the tubular stay and a head portion of the outer member are positioned closer to each other. As a result, the push rod can be pushed by the head portion of the outer member when the operation cable is pulled.
