摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： A hydraulic shock absorber that can reduce outflow amount of oil by maximally removing an oil film attached to an outer periphery of a rod and that can achieve securement of high slidability between the rod and a rod packing and prevention of wear of the rod packing. A rod packing interposed between an outer periphery of a rod and an inner periphery of a rod-side end wall includes a first lip for scrapping off an oil film attached to the outer periphery of the rod, and a ring-shaped grease holding member for supplying holding grease to the outer periphery of the rod. The grease holding member is in contact with the outer periphery of the rod at a position closer to a rod distal end than the first lip.

摘要： A main-bearing outer diameter of an electric motor is made smaller than a rotor outer diameter without causing a drop in production efficiency, and the ease of performing a shrink-fitting step is also enhanced by making it possible to mount a rotor to a main shaft in an early stage. A bearing journal portion (14b) of a main shaft (14) of an electric motor is formed in a shape into which an inner race (18b) of a main bearing (18) can be press-fitted from both sides in the axial direction thereof, and, in addition, an outer diameter of the bearing journal portion (14b) is made larger than an outer diameter of a rotor press-fitting portion (14a), whereas a bearing bore portion (5a) of a partition member (5) is formed in a shape into which an outer race (18a) can be press-fitted from both sides in the axial direction thereof. It is preferable that a space (S) into which a press-fitting tool for press-fitting the main bearing (18) can be inserted be provided between the rotor press-fitting portion (14a) of the main shaft (14) and the bearing journal portion (14b) thereof.

摘要： Embodiments of the present invention help to adjust the recess depth of a head element portion of a head slider. In an embodiment of the present invention, in a test step in manufacturing an HDD, the HDD examines the recess depth of a head element portion and decreases and adjusts the recess depth if the recess depth of the head element portion does not satisfy the predetermined condition. The HDD moves an actuator to a ramp of a retract position and supplies power to a heater in a head slider. If the heater power is large, the head element portion undergoes plastic deformation. The plastic deformation of the head element portion decreases the recess depth of the head element portion.
