Title: Ultrasonic probe
Inventor: TANAKA HIROTSUGU
IPC: G01N29/04
Filed: 1987-04-14
Abstract: PURPOSE:To prevent a vertical ultrasonic wave from being generated in a material to be inspected and to form a flaw detector with a good S/N by providing an ultrasonic wave absorber at a specific position on the surface where the wedge of a probe contacts an acoustic coupler. CONSTITUTION:The ultrasonic wave absorber 9 made of an elastic body is provided over the entire surface which is the surface behind the point where the sound pressure is maximum on the surface where the plastic wedge 3 of the ultrasonic probe 1 contacts the acoustic coupler 4 and <=-10dB in sound pressure from the point where the sound pressure is maximum. The main lobe of the strong sound pressure is propagated to the surface of the material 7 to be inspected, but the side lobe 6 of small sound pressure is absorbed and attenuated by the absorber 9. Consequently, the vertical ultrasonic wave is prevented in the material to be inspected and any echo which becomes a noise component is not generated in a flaw detection gate 8, so the probe with the good S/N is obtained.

Title: Display device
Inventor: YOSHIDA MASATO
IPC: G08B5/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To automatically discriminate the fact that a display device is lost or stolen by providing a memory erasing part for erasing contents described in a storage part when an attachment/detachment detecting part detects detachment from a prescribed attaching position. SOLUTION: When the mounted display device is detached, an attachment/ detachment detecting part 51 detects the detachment and reports it to an alarm generating part 52 and a memory erasing part 53. While receiving the notice from the attachment/detachment detecting part 51, the alarm generating part 52 sounds noises. Thus, it can be reported to the surrounding that the display device is not mounted in a normal state. While receiving the notice from the attachment/detachment detecting part 51, the memory erasing part 53 erases data stored in the storage part. Thus, the data stored in the storage part is prevented from being read out and maliciously used by the third person.

Title: Manufacture of superconductive thin film
Inventor: INASAWA SHINJI
IPC: C23C14/08
Filed: 1987-04-14
Abstract: PURPOSE:To manufacture a good-quality thin film productively by arranging targets face to face and forming the thin film made of a superconductive material on a substrate by spattering. CONSTITUTION:Targets 2, 3 are arranged face to face and spattered to form a thin film made of a superconductive material on a substrate 30. Since the targets 2, 3 do not face the substrate 30, shocks by gamma-electrons and recoil argon are not applied to the substrate. The substrate is not damaged, and such a problem that the composition of the formed thin film is deviated from the preset composition does not occur. A thin film with the preset composition ratio can be formed stably, and a thin film excellent in the superconductive characteristic can be formed. Thin films can be formed on multiple substrates 30 with one spattering, and many thin films with the uniform thickness can be manufactured.

Title: Thermal printer
Inventor: OTSU KENJI
IPC: G06K15/10
Filed: 1988-04-15
Abstract: PURPOSE:To improve thermal interference between heating elements without changing a dot density, by a method wherein the heating elements aligned in a line are not disposed at right angles to a head travel direction but inclined at a predetermined angle. CONSTITUTION:In a thermal head 1 on a coordinate, n-pieces of heating elements 21-2n are aligned at equal intervals on a straight line inclined at an angle of theta deg. to an axis Y, which is at right angles to an axis X, i.e. a head travel direction. Because the heating element alignment is disposed at an angle of theta deg., a distance between adjacent heating elements 21-2n is made 1-costheta deg. longer than that in the prior art with the alignment on the axis Y. Thus, the heating elements 21-2n hardly interfere with each other. On the other hand, if the issuance time of electric instructions to be applied to the heating elements 21-2n is controlled so as to be offset by a fixed value in the order from 21 to 2n as the head travels, a recording can be carried out with the same density and sharpness as observed in the prior art.
