Title: Production of waveguide lens
Inventor: SEKI MASAFUMI
IPC: G02B6/124
Filed: 1985-10-14
Abstract: PURPOSE:To permit working with good accuracy by providing a stage for forming a concave curved face part having a geodesic lens shape by machining to a substrate consisting of crystallized glass and stage for forming an optical waveguide to the substrate surface. CONSTITUTION:The concave curved face 3 constituting the geodesic lens is worked by using a grinding tool 2 consisting of a high speed steel, etc., on the surface of the free-cutting crystallized glass substrate 1 consisting of the crystallized glass internally contg. the fine-grain crystal of mica. The top end face 2A of the grinding tool 2 is preliminarily formed to the curved face of the geodesic lens and an aq. soln. of, for example, cerium oxide is coated on the face 2A of the grinding tool 2 and said face is pressed to the surface 1A of the substrate 1 at about 300rpm to machine the surface and to form the geodesically curved face 3. The waveguide layer 4 consisting of three layers formed and laminated with transparent dielectric materials is formed on the substrate surface. The crystallized glass internally contg. the fine-grain crystal of mica has the extremely good machinability. The concave curved face part constituting the geodesic lens is thereby easily machined with the high shape accuracy.

Title: Motor driven steering control device
Inventor: NISHIKAWA KENJI
IPC: B62D113/00
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To detect an abnormality of a steering mechanism rapidly and surely by considering that the state where an excess current flow continues as long as the duration of the state where the excess current does not flow is less than a second threshold value once the excess current flows through an electric motor. SOLUTION: A main CPU 28 monitors an excess current detection flag by a predetermined cycle. When the excess current detection flag continues to be ON, a first counted value is incremented per predetermined cycle and when this first counted value reaches a first threshold value, a contact of a relay 36 is turned off and then, an electric current circuit from a power source to a DC brushless motor 17 is cut off. When the excess current detection flag is turned off, a second counted value is incremented. When the excess current detection flag is turned on again while the second counted value is less than a second threshold value, the second counted value is initialized, and after confirming that the first counted value is less than the first threshold value, increment is continued without initializing the first counted value.

IPC: B02C19/00
Filed: 1993-08-23
Abstract: PURPOSE:To reduce the size and weight over the entire part of the device, to save a floor space and to promote the recovery and reutilization of empty bottles by arranging a bottle charge port on one side of a bottle transporting path and a bottle striking means on the other and installing this bottle transporting path by inclining the path in such a manner that the bottle charge port faces upward. CONSTITUTION:The empty bottle 17 is dropped by its own weight by inclination of the transporting path 1 and is brought into collision against a moving striker 8 when an operator opens a cap 4 by operating an opening/closing handle 12 and charging the empty bottle 17 from the bottle charge port 2 into the transporting path 1. The bottle is then broken by a striking piece 30 and part of the broken pieces thereof drop from a grid 10 into a recovering container 50. The splinters larger than the grid 10 further collide against a striking piece 31 and drop from the grid 10. The glass which is not crushed by the striker 8 or is not dropped from the grid 10 glides down on the transporting path 1 and further falls downward until the glass is again struck again by a striker 9 and is thus crushed. This striker 9 has striking pieces 32 and 33 like the striker 8 and strikes and crushes the glass in two stages. The crushed glass falls from the grid 10 into the recovering container 50.
