Abstract: PURPOSE:To reduce the thickness and weight of the progressive multifocus lens for eyesight improvement and long-sightedness correction by making the curvature on a main meridian curve parallel to the curve different from the curvature perpendicular to it. CONSTITUTION:This progressive multifocus lens which varies in refractive index between a long-sightedness center A and a short-sightedness center B to give an addition and the difference rho=¦rhos-rhot¦ between the curvature rhos on the main meridian curve M perpendicular to the curve M and the curvature rhot along the curve M is made larger than zero in at least one of a long-sightedness part area and a short-sightedness part area. With a curve C1 passing the long-sightedness center A and a curve C2 passing the short-sightedness center B, the lens curved surface is so formed that the angle containing the normal of the lens curved surface and a plane containing the main meridian line M is equal to variation in refracting power between the long-sightedness center A and short-sightedness center B on the main meridian curve M in the long-sightedness part area and short-sightedness part area.

Title: Solid electron beam generator
Inventor: MIYAWAKI MAMORU
IPC: H01J1/30
Filed: 1986-08-12
Abstract: PURPOSE:To improve electron emission efficiency by injecting electrons from a 1st range to a 2nd range and emitting electrons from the end surface of the 2nd range. CONSTITUTION:A heterojunction structure comprising a 1st layer 8 including a 1st band gap and a 2nd layer 10 including a 2nd band gap which is narrower than the 1st band gap is formd on an epitaxial film 2 of GaAs provided on a substrate 1 of Si, and electrons are injected from the 1st layer to the 2nd layer 10, while the electrons are emitted from the end surface of the 2nd layer. Due to difference of band gaps between the layer 8 and the layer 10, spikes are formed in the boundary. Therefore quantity of carriers injected from one semiconductor to the other is increased compared to a structure with uniform band gaps. Since carries in the hot form ar directly emitted to the external instead of being transmitted in the semiconductor, they are not subject ti scattering. Thus electron emission efficiency is extremely improved.

Abstract: PROBLEM TO BE SOLVED: To provide a leak countermeasure device in a pure water producing apparatus wherein an influence by a leak accident can be reduced by a simple method. SOLUTION: A water feed request signal from a pure water consuming equipment is generated to start feeding water, and when the water feed request signal is continued even after a predetermined time T, an output signal of a three-input AND circuit 3 is set to L.
