Title: Multinozzle ink jet head
Inventor: TOKUNAGA KAZUMI
IPC: B41J2/055
Filed: 1987-02-20
Abstract: PURPOSE:To make the driving voltage characteristics of a plurality of nozzle constant, by changing the cross-sectional area of each orifice with in a predetermined range. CONSTITUTION:A plurality of electrostriction elements 23 are adhered to the diaphragm parts 22 of a plurality of ink chambers 21 on the side opposite to the ink chambers 21 by an adhesive. In making orifice forming parts 13 to a thin plate 1 by etching, both sides of the thin plate 1 are easy to advance in etching as compared with the central part thereof and the thicknesses of the diaphragm parts on both sides become thin and, therefore, the jet speed from each of the nozzles positioned on both sides of a head to which constant voltage is applied becomes higher than that of the nozzle positioned at the central part thereof. However, the correction of the jet speed can be performed by reducing the diameter of the orifice of the nozzle at the central part of the head. When the effective cross-sectional area of the orifices exceeds 20%, an ink particle becomes large and ink flows out or blurs. When the effective cross-sectional area becomes -20% or less, since the injection of the ink becomes unstable, the parameter of the effective cross-sectional area of the orifices is restricted to a + or -20% range.

Title: Recorder
Inventor: MOTAI HIDEKAZU
IPC: B41J13/10
Filed: 1990-02-23
Abstract: PURPOSE:To prevent a printing surface of a recording medium from being stained by the contact of a recording means mounted on a carriage by providing a presser member that is mounted on at least one point of the carriage for pressing the recording medium against a platen. CONSTITUTION:On a carriage 4, a roller 6 for pressing a recording sheet 1 against a platen 2 is mounted through an arm 7. The roller 6 is made of a urethane material having cushion properties and absorption properties. When the recording sheet 1 is fed to the platen 2 and recording is started, the arm 7 is rotated by a control part 8 provided with a solenoid to press the roller 6 against the recording sheet 1. The carriage 4 is moved along a guide rail 3. Ink is delivered from a recording head 5 in accordance with recording information to conduct recording. Therefore, since the recording sheet 1 is positively pressed against the platen 2 by the roller 6 prior to the recording head 5, a printing quality can be improved. In addition, the possibility that the bulging recording sheet 1 may come into contact with the recording head 5 and result in a printing surface being stained is eliminated.

IPC: B43L13/00
Filed: 1988-02-24
Abstract: PURPOSE:To allow a detecting part to face a part to be detected for a long time to prevent the erroneous detection of the detecting part, by a method wherein the long-size part to be detected is disposed on the side of a platen so as to face the travel path of the detecting part provided on a pen head. CONSTITUTION:A detecting part 40 of a pen head 20 is relatively moved at high speed toward long-size parts to be detected 36, 38 disposed on the side of a platen 28. At this time, if the detecting part 40 fails to work when reaching one end of the part to be detected 36 or 38, the long form of the part to be detected 36 or 38 allows the detecting part 40 to face the part to be detected 36 or 38 for a long time. Thus, the detecting part 40 is necessarily actuated before it reaches the other end of the part to be detected 36 or 38. Therefore, the erroneous detection of the detecting part 40 can be prevented.

Abstract: PURPOSE:To carry out an objective determination escaping from any personal error by providing a displacement sensor detecting a condition of a joint part of a tire rubber as a displacement and a photoelectric sensor detecting a reflecting tape of the fixed length as the reference width signal. CONSTITUTION:A displacement sensor 4 detects the condition of a joint part of a tire rubber 2 as a displacement to output a displacement signal 17 via an amplifier 6. A photoelectric sensor 5 detects a reflecting tape 3, which adheres to the joint position of the tire rubber and is the fixed length, to output a reference width signal 16 in the circumferential direction. A clock circuit 11 measures a width of a signal, for which the signal 17 is waveform-processed via comparators 9, 10. A clock circuit 12 measures the time of the signal 16 via a comparator 7. A computing unit 13 computes the condition of the joint part of the tire rubber 2 on the basis of the measurement results in the clock circuits 11, 12 and an indicator 14 indicates this as an absolute amount. In other words, the condition of the joint part is found from the reference signal width time of the tape 3 and joint part condition signal time, so that the open/ lap amount is outputted to the indicator 14.

Title: Method of wire bonding, and registration of reference image
Inventor: MIYAZAKI NAOKI
IPC: H01L21/60
Filed: 1990-02-21
Abstract: PURPOSE:To enable automatic registration of a reference image by determining the likeness between an input image and part of it as a reference to produce the optimal reference image for bonding, which is the image presenting the maximum difference in likeness between the most likely point for the reference and the next most likely point. CONSTITUTION:A camera 5 takes the image of an object 1. As a reference, part of the image is input to a reference image processor 14, and it is sent through a reference image register 15 to a likeness detector 18 for correlation between the input image and reference image. The detector 18 extracts likely points 21 beyond threshold correlation from the input image, while other detectors 22 and 24 detect likely points for the closest and the next closest correlation, respectively. An optimum reference image detector 27 extracts a reference point of the closest correlation among all the most and next most likely points on the object. The detector 27 outputs the coordinates of the reference point to form the optimum reference image for bonding. The registration of the reference image is automatically performed, in this manner, to determine the bonding position with high positional recognition and low recognition jam rate.

Filed: 1994-03-11
Abstract: PURPOSE:To reduce the noise of a laser diode and to perform a stable recording and reproducing by allowing an optical pickup to obtain an output signal based on both a p-polarized light and an s-polarized light. CONSTITUTION:In the case where a double refraction is not present in an optical disk, the components of an incident light being made incident on a second photodetector are the reflected light of the s-polarized light 70% and the reflected light of the p-polarized light 30%, and in total, the outgoing light of the laser diode is made incident on the photodetector by 100%. On the contrary, in the case where the phase difference of the double refraction of the optical disk is 60 deg., an incident light being made to incident on the second photodetector is 86% by adding the s-polarized light and the p-polarized light and the turned-back light quantity to the laser diode is 14%. An RF envelope display is shown is figure (c) to grasp visually the change of light quantities, the figure shows that the turned-back light quantity is smaller than that of a conventional device and the incident light quantity to the photodetector is increased. Thus, the S/N of the diode is improved and the stable recording and reproducing is performed.
