Title: Work mounting base
Inventor: YAMAGUCHI MASAO
IPC: B23Q3/02
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a work mounting base on which a work can be supported accurately according to the shape on the surface of the work even when a work support pin tilts. SOLUTION: Many work support pins 9 are supported by a frame body 4 at the work mounting base 1. The upper ends of work support parts 9a constitute a work mounting face M. A very small gap is ensured between respective large-diameter parts 9b at the pins 9, and the raising and lowering operation of the pins 9 to their axis-line direction is permitted. When a clamp fitting 17 is made to protrude into a pin housing space 6, the pins 9 as a group are pressed, their crowding degree is increased, and the very small gap between the large-diameter parts 9b is eliminated. As a result, a sliding contact resistance between the large-diameter parts 9b is increased, and the pins 9 are fixed so as to be not ascendable and descendable. A vibration giving body 21 gives a vibration to the pins 9, and the pins 9 are corrected to an upright state so as to be ascendable and descendable.

Title: Method for forming electrode of ink jet recording head and ink jet recorder
Inventor: SEO NAOYUKI
IPC: B41J2/16
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To resolve the problem of a conventional method for forming electrode of ink jet recording head such as that, when an electrode is formed by evaporation from the head top part of a channel separation wall to a prescribed depth of an inner wall, a drive voltage becomes high or ink ejection speed varies due to the unevenness of a metal film thickness of the lateral inner walls of the channel so that the positional precision of dot worsens to pose a factor for the deterioration of a recording quality. SOLUTION: After the electrode 4 is formed on one side face of the separation wall 3 of an actuator member 9 at an evaporation angle θ1 to a prescribed film thickness, a metal film 12 having a laterally equal film thickness is formed on the separation wall 3 by varying the evaporation angle θ2 corresponding to the film thickness of the evaporated metal film 12, and conducting evaporation on the side face in apposition to the separation wall 3. Thus, the drive voltage can be lowered and ink ejection stability can be improved.
