Title: Tilt extent detecting device for disc
Inventor: IDE TSUNEO
IPC: G11B7/09
Filed: 1985-09-25
Abstract: PURPOSE:To always detect stably the tilt extent of a disc without a problem such as mis-detection by using only one photodetecting element. CONSTITUTION:One position detection semiconductor element 5C is used for the photodetecting element, a lens, etc., are assembled between a light emitting element and the photodetecting element so as to focus a spot on the position detection semiconductor element. That is, when the disc 1 is deformed and an angle is tilted by DELTAtheta1, the light from the light emitting element 5A is reflected on the disc 1 by the angle of 2DELTAtheta1 to change the irradiated position of the spot on the position detection semiconductor 5C. Since the spot position is changed on the same position detection semiconductor 5C, the tilt extent is easily extracted as an output signal. In this case, since only one photodetecting element is used, there is no problem such as mis-detection due to the difference in the characteristic between two elements which has been a problem in a conventional system and the tilt extent of the disc is always detected stably.

IPC: B41J15/16
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce the incidence of an error in feeding a sheet by a thermal transfer printer which creates a print sheet for display. SOLUTION: The power of a stepping motor 6 is transmitted to a platen roller 9 and a sprocket wheel 11 through a reduction gear mechanism.

Because of the pressing force of the bolt 27, the whole bodies of upper and lower inserting metallic parts are strongly pressed against the inner peripheral surface of the conduit 22 and firmly attached and fixed to the inner peripheral surface by a downward vertical force.  In addition, the front end section of the lower inserting metal fittings 19 is bent outward along the mouth of the conduit 22 and formed in a notched shape having no projecting section protruded toward the center of a manhole. Therefore, the total length of a cable tension detecting device is reduced and the tension detecting section of the device is brought nearer to the mouth of the conduit 22.

IPC: H01J9/227
Filed: 1990-08-13
Abstract: PURPOSE:To enhance tolerance in forming a black matrix(BM) film and adhesive strength in forming a phosphor(PH) film and prevent both the films from deviating from the positions, by performing exposure at the time of forming the BM film keeping a greater distance between a light source and a shadow mask than at the time of forming the PH film. CONSTITUTION:An exposure unit having a diameter A of a light source larger than that in forming a phosphor(PH) film stripe 7 is exposed in forming a black matrix(BM) film stripe 6. Therefore, tolerance in forming the BM film strip 6 as well as adhesive strength of the PH film stripe 7 can be enhanced. Since the difference in thickness between a photoresist and a phosphor slurry is considerable, exposure is performed at the time of forming the BM film, keeping a greater distance between the light source and a shadow mask than at the time of forming the PH film in consideration of the difference, thereby preventing the PH film and the BM film from deviating from the positions.
