Title: Magnetic head
Inventor: KOSEKI HIDEO
IPC: G11B5/127
Filed: 1988-01-25
Abstract: PURPOSE:To widely decrease a magnetic flux to leak from the side surface of a head and to improve head efficiency by holding the both surfaces of a metallic magnetic thin film, which is a main core, with a superconductor. CONSTITUTION:The both surfaces of a metallic magnetic thin film 1, which is the main core, are held by a superconductor 2. For example, on the both surfaces of a superconductor substrate 2, whose thickness is 1mm, an amorphous alloyed thin film 1 is formed and on the film, an SiO2 film is formed as a protecting layer. Further, on the both surfaces of the superconductor substrate, a glass layer, whose thickness is 3mum, is prepared. Then, the three pieces of the former and the four pieces of the latter are alternatively laminated and adhered at a glass fusion temperature. Then, a laminating block is obtained. Thus, the side surface of the magnetic head is covered with the superconductor and the leakage of the magnetic flux in the side surface of a magnetic path, which is composed of the metallic magnetic thin film, can be extremely decreased by a Meissner effect. Then, the efficiency of the magnetic head can be extremely improved.

Title: Thermal head
Inventor: MORIYA BUNJI
IPC: B41J2/335
Filed: 1988-01-25
Abstract: PURPOSE:To inhibit the scatter in the amount of adhesive to be applied so as to obtain a thermal head having stable properties by applying adhesive only to the top of a projecting portion, while allowing extra adhesive to flow into the side groove portions thereof, and by keeping the bonding area between a ceramic board and a mounting plate constant. CONSTITUTION:In a case where a mounting plate having a width W2 which is wider than a ceramic board having a width W1 is fixedly bonded to the ceramic board, the mounting plate is constructed such that it has a projecting portion 5 having a width a provided at a central portion thereof and grooves 3, 4 formed on each side of the projecting portion 5, which is made lower than the side portions of the mounting plate. In other words, the height of the projecting portion 5 is made lower than the distance B between the bottom of the grooves 3, 4 and the top surface of the mounting plate so as to produce a distance (b) between the top surface of the projecting portion 15 and the ceramic board, and an adhesive 6 capable of holding the rubber elasticity after cured, i.e. a rubber adhesive, is filled thereinto. The ceramic board 1 and the mounting plate 2 are bonded together with this rubber adhesive. In this case, even if the adhesive 6 is applied in the amount slightly more than what is required, the extra adhesive flows into the grooves 3, 4 formed on the sides of the projecting portion 5, thereby accomplishing constant stable bonding.

Abstract: PURPOSE:To make the fingers of a robot reach a desired position quickly and exactly without making a teaching device heavy and complicated, by providing a manual data input function key which can designate numerically a moving extent of a robot moving axis. CONSTITUTION:In case a teaching work is ended by advancing an X axis by 1m, an operator decides whether a manual data input (MDI) command is executed or not. 1m is a large value, therefore, when it is considered to execute manually a movement, a robot is moved to 10cm before a target position by selecting a speed by a speed selecting key 49 without depressing an MDI key 57, and depressing an axis moving key 45. Subsequently, the operator can select the key 57. When an executing key 51 is depressed after designating 8mm. by a ten-key part 39, the X axis advances by 8mm.. Positioning is completed by determining the remaining 2mm. by an inching operation. In this case, when 2mm. can be set numerically and exactly, the robot is moved by an MDI function.

Filed: 1988-01-26
Abstract: PURPOSE:To enable large-sized light-capacity display of STN, NTN, ferroelectric liquid crystal, etc., by having a stage for coating a patterned resist on the transparent electrode coated on a glass substrate. CONSTITUTION:The transparent ITO electrode is coated to 2,000Angstrom by a sputtering method on, for example, soda glass subjected to a passivation treatment with SiO2. The sheet resistance is 10OMEGA/sq. The positive type resist is then formed to the prescribed pattern with a photo stage. The transparent ITO electrode is then patterned by etching with a hydrochloric acid soln. of ferric chloride. The substrate is then sent to the next stage without stripping the resist. Ferrite is coated on the surface for about 5min to about 2,000Angstrom  (thickness of the transparent electrode) by a spraying or spin coating method. The resist is stripped by an alkali and the substrate is subjected to curing for 10min at 1,000 deg.C to obtain the liquid crystal panel substrate. The substrate is subjected to the prescribed orientation treatment and the liquid crystal panel of the STN display is assembled. The large-sized high-capacity display is thereby enabled.

Title: Optical fiber stress providing sensor
Inventor: OTA JUNICHI
IPC: G01D5/26
Filed: 1990-01-26
Abstract: PURPOSE:To make the influence of high-order modes small by providing a 1st clad which has a less refractive index smaller than a core and a 2nd clad which has a higher refractive index than the 1st clad. CONSTITUTION:In a sensor part 5 which is stressed to deform, light pulses sent in an optical fiber 4 from the side of an OTDR 3 generate backward scattered light to generate optical transmission loss. Consequently, reflected light from the sensor part 5 to the OTDR 3 is reduced and the stress in the sensor part 5 can be detected by the OTDR 3. Namely, the refracting index n2 of the material forming the 2nd clad 8 is larger than that of the 1st clad 7 and less than that of the core 6, so the high-order mode which enters the 1st clad 7 from the core 6 as the backward scattered light is generated becomes easy to enter the side of the 2nd clad 8. Consequently, the attenuation of the high- order mode in the optical fiber 4 becomes extremely large.
