Title: Reading device
Inventor: FUKUI TAKESHI
IPC: G02B1/10
Filed: 1984-02-01
Abstract: PURPOSE:To prevent the deterioration of reading performance of a device which reads originals optically by using SiOxNy (x>0, y>0) to form a protecting layer. CONSTITUTION:The 1st electrode 2 is formed on a substrate 1, and a photoelectric conductor 3 is formed on the electrode 2. Then a 2nd electrode 4 is formed on the conductor 3 with a light transmitting material, and a protecting layer 8 is formed on the electrode 4. The layer 8 is formed with SiOxNy (x>0, y>0) and therefore excels in the wear resistance with high hardness and reduced flaws. Furthermore the transparency is kept satisfactory for a long period of time with a small refractive index for the layer 8. Thus the incident angle at which the total reflection is caused in increased at the interface of air between the layer 8 and the original 9. This reduces the generation of noises.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a power element without being affected by external noise by incorporating one or plural circuits among an overcurrent detection circuit, overheat detection circuit and a control power voltage drop detection circuit in a semiconductor element and arranging an oscillation circuit outside the semiconductor element. SOLUTION: One or plural circuits among the overcurrent detection circuit 1b, the overheat detection circuit 1c and the control power voltage drop detection circuit 1d, a stop circuit 1f and the power element 1a having a switching function are incorporated in the semiconductor element 1.

Here, a drain groove 12 is formed to the left side as illustrated from the center line 11 of the brake surface 7 and a groove 13 deeper than the drain groove 12 is formed in the central part. Close to the rear end of the main body 5 is formed an equilateral triangle hole 14 and one vertex 14a of this hole 14 is located so that it may face the front end side of the main body 5. Accordingly, through the main body 5 becomes oblique by some cause, the rear end 10 is bent in the reverse direction against the rim 6 because there is the hole 14 when the rear end comes in contact with the rim 6 and so the rear end 10 comes in surface contact C with the rim 6. Accordingly, the linear contact by the front end alone can be avoided to realize the intended purpose.
