摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a high quality share mode inkjet head whereby precise electrodes in high density and precise solid wiring patterns in high density can be formed by a simple and highly reliable method as compared to heretofore and leakage of ink, or falling or cracking of a partition wall between channel grooves does not occur. SOLUTION: A piezoelectric element plate is subjected to mechanical grinding to form the channel grooves 2. After vertical grooves 6 communicating with the channel grooves 2 are formed by emitting a laser light, the plate is subjected to electroless plating. A head substrate 5 is abraded to form longitudinal wiring patterns. The laser light is emitted to the head substrate 5 to form lateral wiring patterns communicating with the longitudinal wiring patterns. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To prevent deterioration in quality due to a heat generated in laser processing for forming an electrode and oxidation occurring upon removing a catalyst. SOLUTION: There is disclosed a method of manufacturing an inkjet print head for ejecting ink from a channel. After the catalyst is absorbed to a member A including a piezoelectric material, the member A is dipped into a liquid and a part of the catalyst is removed by emitting a laser light D thereto and the catalyst which is not removed by the laser light D is subjected to a plating treatment, and then a desired plating film is formed to form an electrode having a desired film thickness. After the catalyst is absorbed to the member A, the member A is dipped into a plating liquid to apply a plating treatment thereto and the laser light is emitted to a part of the member A during the plating treatment, and then a desired plating film is formed at the part which is not removed by the laser light D to form a desired plated film, thereby forming an electrode having a desired film thickness.

摘要： PROBLEM TO BE SOLVED: To form connecting electrodes and electrodes of a high-speed, high- image quality and high-density ink jet printing head in a combination of plating and laser patterning, and form a high-density and solid wiring by removing unnecessary parts by a laser during plating or before plating simply as compared with the conventional method in which patterns are formed by removing unnecessary electrodes and a plating metal by the laser after plating. SOLUTION: In a method of manufacturing the ink jet printing head for jetting ink from channels by forming the channels to a member including a piezoelectric body, impressing a voltage to the electrodes set to the piezoelectric body and driving the piezoelectric body, at least one side face and a bottom face of a channel plate having grooves for a plurality of the channels are plated with a catalyst adsorbed, whereby a plating thin film thinner than a desired film thickness is formed. Then, the plating thin film is partly removed by a laser beam and plated again. As a result, a further plating film is formed on the plating thin film not removed by the laser beam. Electrodes of the desired film thickness are formed accordingly.

摘要： PURPOSE:To record magnetic information with a specified constant recording density even if the moving speed of a film is changed and to reproduce the recorded information, at the time of recording/reproducing the magnetic information on the film having the formation of a magnetic layer on a base layer. CONSTITUTION:The moving speed of the film 2 is detected by a speed detector 3 and film moving speed information is outputted to a transfer device 12, an encoder 5, a writing device 6, a read-out device 9 and a decoder 10. When the rotational speed of a rotary drum is detected by a rotary encoder, the film moving speed information is outputted via a multiplying circuit. Then, the pulse signal vout of a frequency fout used as a clock signal for operation is outputted to the encoder 5 and the decoder 10.

摘要： PURPOSE:To possess a function for making a magnetic head follow curling of a film at both ends by providing two arm parts consisting of elastic members inclined from both ends of a fixing part and equipping 1st supporting arms of extensions of these two arm parts intersecting a track middle part of the head. CONSTITUTION:The arm parts in the 1st supporting arms 2a1, 2a2, 2b1 and 2b2 are formed with their extensions to be intersected in the track middle part of the head, and when the film is curled at right angles to its traveling direction, no track deviation takes place even upon an angular change of the head. Film guides 5a and 5b are fixed to 1st supporting parts 4a and 4b so as to make their space from each other narrower than the width of the film by approximately 1mm, where 2nd supporting arms 3a1, 3a2, 3b1 and 3b2 as of parallel leaf springs are provided. Consequently, the heads 1a and 1b engaged always with both ends of the film are also moved parallel to the film surface by the film guides 5a and 5b, so that a relative surface angle between the film surface and the head surfaces is not changed at all.

摘要： PURPOSE:To prevent the function from being incomplete because of sticking of foreign matters by suspending a floppy disk (FD), whose function is incomplete because of sticking of foreign matters, in a washing liquid to wash away foreign matters. CONSTITUTION:First, a water washing liquid is selected as the washing liquid, and it is preferable that the water washing liquid is switched to an organic solvent liquid incompatible with the binder of an FD 1 for persistent oily stain which is left unwashed away by water washing. With respect to the washing method, it is preferable that the FD 1 is suspended in the washing liquid and is immersed to a sufficient depth. FDs 1 are suspended in the washing liquid by holders 2 without being brought into contact with the other objects such as a washing tank and the FDs 1 of one another in case of continuous treatment. Ultrasonic waves having 30-50kHz frequency are radiated to FDs 1 suspended in the liquid and these FDs 1 are rotated and/or reciprocated upward and downward. Thus, the functions of FDs 1 are restored from incompletion.
