Abstract: PURPOSE:To obtain a semiconductor light emitting device in which the outline of dots formed as a latent image is clear by a method wherein LEDs are limited in refractive index, and at least the side faces of the LEDs are covered with a protective film prescribed in refractive index. CONSTITUTION:An LED array is provided onto a substrate 1, each LED 5 is provided with an N-type semiconductor layer 3b and a P-type semiconductor layer 3c both of AlxGa1-xAs crystal, the refractive indexes nLED of the LEDs 5 are so set as to satisfy a formula, 3.44<=nLED<=3.60. The side faces of the LEDs are covered with a protective film 9 which partially transmits and reflects light, the refractive index n of the film 9 is set to satisfy formulas, 1.85>n or n>1.90. Letting the refractive index and the thickness of the film 9 be n and d respectively, the light wavelength of an LED be lambda, n, d, lambda, and m are so set as to satisfy a formula, nd=mlambda/2 where m is an integer. Therefore, light emitted from the side face of an LED is less reflected from another LED adjacent to it, so that a sharp image can be obtained when an LED array of this constitution is used as an exposure light source.

Title: Adjusting valve
Inventor: OGAUCHI TOSHIO
IPC: F16K47/04
Filed: 1984-04-02
Abstract: PURPOSE:To adjust either of the whole length of a flow passage or the sectional area of the flow passage by forming the fluid flow passage so that the flow passage becomes longer than the whole length of the fluid passing part and adjusting an inner valve engaged with the flow passage. CONSTITUTION:The screw at the part corresponding to the whole length L of the fluid passing part of the body is formed into a tapered form at a prescribed angle (alpha) so as to be made thinner towards a valve seat 4, and the outer peripheral edge of the convex spiral 11 of an inner valve 2 is closely engaged with the inner peripheral wall of the spiral groove 3 of the valve body 1 when the valve is perfectly closed, and the fluid passage for the fluid is not formed when the valve is perfectly closed. When the inner valve 2 is shifted from this state, a gap is formed between the convex spiral 11 and the spiral groove 3, since the spiral is formed into tapered form thinner towards the top edge, and a spiral-shaped fluid passage 8 is formed. The whole length of said spiral flow passage becomes shorter, as the inner valve 2 shifts to a valve rod 5 side.
