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.

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 constructoin of a magnetic recording medium provided with one circular track for magnetic graduations and another circular track for standard marks, the standard marks are accompanied with specified magnetic identification marks so that discrimination between the standard marks can be fairly done without any influence by the number of the standard marks only by reading them out together with the identification marks. The medium is advantageously used for displacement detectors such as magnetic rotary encoders and magnetic linear scales.

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 head rest of a vehicle seat may include a head support portion for supporting a head of a passenger, and a drive unit for moving the head support portion. The drive unit has a moving mechanism that is arranged and constructed to move the head support portion toward and away from the passenger head, an actuator for actuating the moving mechanism, a load detecting device that can detect a load applied to the actuator and generate a control signal representative of the detected load, and a controller that can control the actuator so as to control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion toward the passenger head. The controller controls the moving mechanism based on the control signal so as to stop the motion of the head support portion.

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.

It is one object of the present invention to provide a control for moving a head rest in response to a signal from a sensor detecting a distance between the head rest and a head of a passenger, in which even if the head of the passenger moves within a predetermined range, the head rest can be prevented from moving depending on the motion of the head of the passenger so as to remove discomfort for the passenger.Therefore, the present invention has a construction as follows.A head rest control system in which a head rest of a seat of a vehicle is constructed to be moved back and forth by a head rest moving mechanism may include a sensor detecting a distance between the head rest and a head of a passenger, and a control device controllably actuating the head rest moving mechanism. The control device is constructed to actuate the head rest moving mechanism when the distance between the head rest and the head detected by the sensor is outside of a proper range of clearance in which it is possible to deal with a back-side collision of the vehicle, thereby moving the head rest to a proper position in which it is possible to deal with the back-side collision of the vehicle.

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 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.
