Title: Waveguide type optical modulator
Inventor: SHUDO YOSHITO
IPC: G02F1/035
Filed: 1992-08-26
Abstract: PURPOSE:To provide the optical modulator of low loss and low voltage driving by forming a single mode waveguide structure consisting of an org. high-polymer material exhibiting a high primary electrooptical effect. CONSTITUTION:This optical modulator has the structure disposed with a coplanar electrode 11 consisting of metal on the uppermost part (or oxide silicon film of the lower part) and is constituted by using the org. high-polymer material exhibiting the primary electrooptical effect as the material of core layers 8, optimizing the difference in the specific refractive index from the materials of the ambient clad layers 7, 9, 10 to constitute the single mode waveguides and providing the surface of the silicon oxide layer (or upper clad layer) in the lower part with another grounding electrode 6. The confinement of electric fields is thereby increased and the modulation operation with the low voltage is executed. Then, the org. high-polymer material having the high primary electrooptical effect is used as the material of the waveguide layer and the difference in the specific refractive index from the material of the ambient clad layers is optimized to form the single mode waveguide. In addition, the grounding electrode 6 is separately provided in order to increase the confinement of the electric fields of coplanar line type electrodes 11. Further, the spacing between the upper and lower electrodes is narrowed and, therefore, the modulation operation is executed with the extremely low driving voltage.

Abstract: PURPOSE:To eliminate the need to execute processes for polishing the thin piece of an interference film forming substrate and for installing an interference film to an interference film installing groove, by providing a V-shaped groove whose depth reaches the bottom part of a core layer of a dielectric optical waveguide, and forming as one body an interference filter, the optical waveguide, and the branching V-groove. CONSTITUTION:A V-shaped groove 15 having a groove direction being roughly orthogonal to the propagation direction of waveguide light is provided on optical waveguides 12-14 which are formed on the surface of a dielectric multi-layer film interference filter 11. In this state, the waveguide light is reflected by an incident side slant face 15A of the V-groove 15 and led to the dielectric multi-layer film interference filter 11, and when the wavelength of its incident light is in a passing band, it is led to a reverse side 19 of the substrate, and on the other hand, when the wavelength of the incident light is in an obstructing area, the reflected light from the dielectric multi-layer film filter 11 is led to an emitting side slant face 15B of the V-groove 15, and its reflected light is coupled to the optical waveguides 12-14. Accordingly, the interference filter 11, the optical waveguides 12-14, and the branching V-groove 15 are formed as one body. In such a way, a process for working the interference filter 11 to a thin piece, and as assembly process for fixing the interference filter 11 to the interference filter installing groove with high accuracy become unnecessary.

Filed: 1985-11-11
Abstract: PURPOSE:To permit flat light quantity distribution on a photosensitive body and to form an image with high quality by driving each light controlling element array of an optical printer head in such a manner that the quantity of the light emitted by said array is substantially the same in amplitude as the uneven pitch of each imaging element array and is in anti-phase.

Title: Mold
Inventor: IKEDA YUZO
IPC: B29K21/00
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to positively fit a sprue part to a specific split mold during mold opening without allowing the spool part to fit to another split mold by providing a second sprue lock to the outer face of a protrusion with a tapered sprue lock which is formed as an undercut in the inner face. SOLUTION: A second sprue lock 11 of an annular recessed shape is formed on the outer face of an annular protrusion 9 with a tapered sprue lock 10 which is formed as an undercut on the inner face. Therefore, the fitting strength of a sprue part (b) to the second spool lock 11 is added to the fitting strength of the sprue part (b) to the spool lock 10. Consequently, if the fitting strength of the sprue part (b) to the sprue lock 10 is reduced by setting the inclined angle of the taper of the sprue lock 10 at a comparatively lower degree, this angular insufficiency can be compensated for by the addition of the fitting strength of the sprue part (b) to the second sprue lock 11. Thus, it is possible to positively fit the sprue part (b) to a stem 4 during mold opening.

Title: Ignition timing retarder
Inventor: ARAI MICHIHISA
IPC: F02P5/10
Filed: 1983-12-29
Abstract: PURPOSE:To prevent an engine from vibration and stalling, by installing a solenoid valve and also a lever interlock switch, making this valve open, in a suction passage which connects an intake manifold and a vacuum timing control device together. CONSTITUTION:A solenoid valve 5 is installed in a suction passage 4 connecting an intake manifold 3 to a vacuum timing control device 2 being built in a distributor 1. An engine water temperature detecting switch 6 detects engine water temperature and makes the solenoid valve 5 open or close. When a heater control lever 12 is in a position other than its hot position, it makes the solenoid valve 5 open irrespective of the engine water temperature detecting switch 5 being turned to ON or OFF. With this constitution, since the vacuum timing control device 2 is in no case retarded at all, vibration and stalling in an engine are thus preventable from occurring.

IPC: G01V8/20
Filed: 1985-11-12
Abstract: PURPOSE:To detect an IC without enlarging the space dimensions between parts by setting such that one of two optical axes crosses a small size IC transfer lane, the other crosses a medium size IC transfer lane but does not cross a heater. CONSTITUTION:An optical axis B is so set that it crosses a medium size IC2b on a small size IC transfer lane La, does not cross a medium size IC2b on a medium size IC transfer lane Lb but crosses a large size IC2c on a large size IC transfer lane Lc. Similarly, an optical axis C is so set that it crosses the medium size IC2b and the large size IC2c but does not cross a small size IC2a. Since the optical axes B and C are substantially vertically set within the range wherein the axes do not cross an electric heater 13a, it results that light projectors and light receivers (4b, 4c) and (5b, 5c) are positioned obliquely below and above a chute rail 11 and a heat block 13, respectively. Therefore, the space dimensions from adjacent rails 11' and 11'' and adjacent blocks 13' and 13'' are not increased.
