Title: Switching power supply
Inventor: HIGUCHI YOSHIO
IPC: H02M1/08
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To make switching between continuous and intermittent switching operations by providing an error detection circuit with a pulse of such a level as the error detection circuit makes a decision that the secondary DC output voltage of a switching power supply increases thereby operating a switching circuit intermittently depending on the pulse. SOLUTION: An error detection circuit 3 comprising a shunt regulator Q4, five resistors R8-R12, and a capacitor C8 detects voltage error of the DC output 21 on the secondary of a high frequency transformer 7. The detected voltage error is fed back to a switching circuit 1 through an insulating element, i.e., a photocoupler 2, in order to stabilize the voltage of the DC output 21. Regardless of the voltage of the DC output 21, a pulse generating section 5 provides the error detection circuit 3 with a pulse of such a level as the circuit 3 makes a decision that the voltage of the DC output has increased thus operating the switching circuit 1 intermittently depending on the pulse.

Title: Light divergence element and production thereof
Inventor: FUJII KIYOSUMI
IPC: G02B6/00
Filed: 1991-06-03
Abstract: PURPOSE:To enhance the divergence uniformity of light and efficiency of the light divergence element constituted in such a manner that the incident light from an end face is divergence from side faces. CONSTITUTION:High-refractive index glass plates are laminated on both side face sides of a low-refractive index glass plate as a center and the laminated surfaces positioned vertically are subjected to a heating treatment so as to be provided with a refractive index distribution by ion diffusion, by which an element 10 is obtd. If the end face 10A positioned on the upper side in this treatment is used as a light incident surface, the refractive index on this side is made lower than on the lower side as a result of the ion transfer and glass flow by gravity. Incident rays 11 on the element are, therefore, bent more largely toward the outer side the nearer the terminal of the element and the light divergence positions to the outside are widely dispersed in the longitudinal direction of the element according to the incident angles. Namely, the diverged light having the high uniformity is obtd.
