Inventor: NAKAYAMA YOSHINOBU
IPC: G02B6/12
Filed: 1989-07-28
Abstract: PURPOSE:To facilitate the manufacture and to eliminate a disconnection point at the coupling part between two optical waveguides by forming one optical waveguide in homogeneous structure, and the other optical waveguide in multi- layered structure. CONSTITUTION:The optical waveguide for TE-TM mode separation has two optical waveguides 3 and 4 which are separated into two area parts on a substrate 1 and contact each other at the coupling part for TE-TM mode separation; and one optical waveguide 3 is formed in homogeneous structure and the other optical waveguide 4 is formed in multi-layered structure. The optical waveguide 3 in homogeneous structure is equalized in equivalent refractive index between both the TE and TM mode, which are both coupled and guided efficiently to the optical waveguide in multi-layered structure. The optical waveguide 4 in multi-layered structure is differenct in equivalent refractive index between both the TE and TM modes and the TE-TM mode separation can be performed with small loss. Consequently, there is no disconnection point at the coupling part between the two optical waveguides, structure with small coupling loss is realized, and the manufacture is facilitated.

Title: Inner emission type liquid crystal display device
Inventor: EBIHARA TERUO
IPC: G02F1/1333
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To perform a bright display even when the periphery is dark by constituting so that light is made incident from a side surface of a light diffusion type liquid crystal panel. SOLUTION: The light emitted from an LED 6 is reflected by a reflection surface 2 to be made incident on the side surface 3a of the liquid crystal display panel 3. The light having an angle exceeding a critical angle on the boundary of the front substrate of liquid crystal display panel 3 of the incident light is closed between with a reflection layer provided on the liquid crystal display panel 3 to be light transmitted. In a light transmission state part applied with a voltage, guided light is transmitted as it is not to be leaked to the outside of the liquid crystal display panel 3, and an observer doesn't feel the light emitted from the LED 6 to see dark. However, in a light diffusion state part being a voltage nonapplied part, the guided light is diffused, and diffused light having the angle smaller than the critical angle is leaked to the outside.  This leaked light becomes the diffused light, and the observer feels bright.

Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily classify and dispose plastic members and electric members by pulling the cables of electric appliances, destroying armors and drawing internal package members outward. SOLUTION: At the time of disposing the electric appliance, there is a need for drawing the electric members, such as capacitors 7 and a transformer 8, which are the internal package members on a circuit board 9 outward from a casing 5 which is the armor and subjecting these members to a classification treatment.

At this stage, current is flowed in the deflecting systems 6-8 so as to give a magnetic field for moving an axes of a lens so that an orbit 19 of the main beam and an axis of the lens 2 coincide with each other. The light passes through a cross over 5, and the light is displaced from the optical axis by a third deflecting system 10', and becomes vertical to a surface of a sample 4 at the center of of a fourth deflecting system 11', and enters the sample 4.  A second projecting lens 3 adjusts the deflecting systems 9-11 so that the electronic optical axis and the orbit of the main beam 18 coincide with each other.

Title: Audio equipment having display device
Inventor: HATSUDA TERUO
IPC: G11B25/10
Filed: 1994-08-22
Abstract: PURPOSE: To make it possible to move a recording medium inserted from a front port on a body to a reproducing position without any trouble even when a reproducing device is arranged further close to a display device by cutting off the rear corner part of the display part which is opposed to the front face of the reproducing device by prescribed quantity or more. CONSTITUTION: A slope 31a is formed by previously obliquely cutting off rear upper and lower corner parts on the whole. A tape deck 23 is arranged extremely close to a liquid crystal display device 31. Since the upper corner part of the body case 31 of the display device 30 is obliquely cut off, trouble is not generated at the time of moving a casette tape 22 to a reproducing position P1 even when the deck 23 is arranged on a slightly forward position. Thereby even when a cassette insertion port 24b on a front panel 24 is formed on the same position as a displaying window part 24a, the tape 22 can be ejected and it is unnecessary to form a step difference between the prot 24a and the window part 24a. Consequently the appearance of the device can be improved, the cost can be reduced by simplifying the shape of the front panel 24 and the tape 22 can be smoothly ejected.

IPC: B21C47/02
Filed: 1981-12-08
Abstract: PURPOSE:To prevent generation of slackness and elongation of a wire by making winding diameter of a V-groove adjustable against winding diameter of another V-groove. CONSTITUTION:When a wire is elongated and slackness is generated, adjusting bolts 28, 28 are operated and a movable body 23 is brought near the main body 22 against springs 31, 31. As the winding diameter D2 on the second V- groove is increased by the operation, D2 is made greater than the winding diameter D1 of the first V-groove 24. The speed of the wire that enters the second V-groove 25 becomes greater than the speed of wire that leaves the first V-groove 24. Thus, elongation of the wire is absorbed and slackness of the wire can be prevented.
