Title: Ink jet recording method
Inventor: SHIROTA KINU
IPC: B41J2/21
Filed: 1992-12-08
Abstract: PURPOSE:To obtain an image which is high in both of image quality and solidity by improving image density of pigment ink by using a dying property of dying ink by a method wherein the pigment ink and the dying ink of which pH is prepared to a specific value or under are impacted onto the same point of a material to be recorded. CONSTITUTION:In a recording head 13, a glass sheet or the like having an ink pass groove 14 is stuck to a heating head 15. When an electric signal is applied to a plurality of electrodes 17-1, 17-2, a specific area (n) of the heating head 15 is heated, and a blowhole is generated in ink 21 coming in contact therewith. Then, a meniscus is projected by pressure, and the ink 21 is discharged. It becomes an ink drop 24, which is impacted onto a material 25 to be recorded from an orifice 22 as the ink drop 24, and recording is carried out. In that case, pigment ink and dying ink of which pH is prepared to 4 or lower are impacted respectively onto the same point of the material 25 to be recorded. Thereby, image density of the dying ink is improved by using the dying property of the dying ink.

Title: Thermal head
Inventor: FUKUDA MITSUHIKO
IPC: B41J2/335
Filed: 1995-12-18
Abstract: PURPOSE: To form a recording pattern on an upper surface of an insulating substrate in one layer by forming a ground electrode to extend linearly in parallel to a long side of the insulating substrate in the vicinity of an edge of the long side. CONSTITUTION: A thermal head substrate 17 is mounted on a heat radiation plate 10. At this time, the thermal head substrate 1 is bonded only at a center 10c of the radiation plate, with the fact taken into consideration that thermal expansion coefficients of the thermal head substrate 1 and the heat radiation plate 10 are different. Besides, the thermal head substrate 1 and heat radiation plate 10 are allowed to freely expand even when the temperature is increased, thereby avoiding warping. A flexible substrate edge part 11a overlaps with an insulating substrate part 2a, having a conductive pattern formed thereon to be connected with connecting terminals 4a, 5, 8a. Since the connecting terminals 5 of a signal system are concentrated at the insulating substrate rear edge part 2a, a flexible substrate 11 can be reduced in width (as well as a reinforcing plate 12).

IPC: H01J37/252
Filed: 1992-12-09
Abstract: PURPOSE:To acquire the information on crystal structure of sample surface easily by providing a slit-shaped electron-taking port at a detection part. CONSTITUTION:A slit-shaped electron-taking port 3 is provided at an electron energy detection part 1. The slit-shaped opening is provided between a measurement sample and an electron detector.

Also, a member with the slit-shaped opening consists of a conductive material and the slit size is normally equal to a slit width, namely approximately 0.5-3mm, depending on a detector where the slit is provided. The smaller the sit width is, the more the effect can be improved. On the other hand, the sensitivity is reduced.
