Filed: 1992-11-02
Abstract: PURPOSE:To prevent an operator from feeling the glare of a screen by varying the screen brightness according to the brightness of operation environment. CONSTITUTION:A screen illuminance measurement part 1 measures the illuminance of external light in-coming to a display screen, a screen brightness arithmetic part 2 calculates a limit screen brightness value at which the glare of the display screen is not felt from the illuminance measured by the screen brightness arithmetic part 2, and a control 3 dims the screen to less than the screen brightness value calculated by the arithmetic part 2. Consequently, display performance which eliminates the glare can be secured irrelevantly to the variation of the light made incident on the screen.

Title: Recording and reproducing device for magnetic sheet
Inventor: TAMURA TOMOAKI
IPC: G11B17/34
Filed: 1985-12-26
Abstract: PURPOSE:To reduce the driving torque of a magnetic sheet while a stable contacting state is maintained between the magnetic sheet and a magnetic head, by forming a habit of bending to the magnetic sheet with a stabilizing member, etc., when the stabilizing member is pushed against the magnetic sheet. CONSTITUTION:Under a condition where a lid 8 is a little lowered, the projecting end face 7E of a stabilizing member 7 is contacted with the outer peripheral margin section of a magnetic sheet 3 and bends the outer peripheral margin section downward together with a magnetic head 5. When the lid 8 is completely closed, the stabilizing members 7C and 7D face the magnetic head 5 with the magnetic sheet 3 in between. Since a bending habit is formed to the outer peripheral section of the magnetic sheet 3, the pushing forces of the magnetic head 5 and stabilizing member 7 against the magnetic sheet 3 are made weak so that the violent behavior and runaway of the magnetic head can be suppressed and a stable contact can be obtained between the magnetic head 5 and magnetic sheet 3. Therefore, the rotating torque of the magnetic sheet 3 can be reduced.

Filed: 1985-12-26
Abstract: PURPOSE:To reduce sharply the number of adjusting processes by forming a metalized layer only a part of a resonator hole and inserting a resonance frequency adjusting member consisting of a metal rod or a dielectric rod into the resonator hole. CONSTITUTION:The metalized layer is formed only a part of the resonator hole 12 without forming the layer on the whole inside, a metallic screw rod 16 is inserted into the resonator hole 12 as the resonance frequency adjusting member and the rod 16 is screwed into the hole 12 and fixed on a required resonance frequency position with an adhesive. When the rod 16 is inserted into the resonator hole 12, the resonance frequency is not changed on the position completely covered with the metalized layer, but when the rod 16 is projected by the length L, the projection is made equivalent to the extension of the metalized layer of the hole 12, so that the resonance frequency is reduced. Consequently, reversible adjustment to obtain a required resonance frequency level can be attained by rotating the rod 16 to change the screwed position.
