Title: Heat sink for laser diode
Inventor: IWASAKI NOBORU
IPC: H01S5/00
Filed: 1990-10-12
Abstract: PURPOSE:To prevent adhesion of a fused material layer which is easily peeled off and enable reduction of let-go of the fused material layer when performing dicing for achieving an improved yield by providing a stage difference so that one part or an entire periphery around a chip surface can be lowered by on stage. CONSTITUTION:After patterning is performed on an Si substrate 1 by using a photo resist, the Si substrate is etched, thus forming a groove 5 in a lattice shape with a pitch of groove of a heat sink. Then, metallized layers 2 and 3 are formed on front and rear surfaces by the sputter method and a fused material layer 4 is formed by deposition using a metal mask of a pattern where the fused material layer part for two heat sinks is connected. Then, a central part of the groove 5 is cut by dicing, thus preventing adhesion of the fused material layer which is easily peeled off on a side surface of the heat sink, enabling let-go of the fused material layer when performing dicing to be reduced, and preventing ball-shaped hardening of the fused material when mounting a pellet.

Title: Water treatment flocculant and its production
Inventor: HASEGAWA TAKAO
IPC: B01D21/01
Filed: 1991-09-27
Abstract: PURPOSE:To make it possible to store for long time with high coagulating effect being maintained by making the flocculant mainly composed of a high polymer silicic acid solution whose alkali metal concentration is made the specific % or less by dealkalizing metal treatment and which has SiO2 concentration of the specific % or more and limiting the viscosity to the specific value or more. CONSTITUTION:As a water treatment coagulant, is used high polymer silicic acid solution whose alkali metal concentration is made about <=0.3% by dealkalizing metal treatment and which has SiO2 concentration of about >=8% and limiting the viscosity to about 0.2(100ml/g). The deakalizing metal treatment is made by passing alkali metal silicate solution through an ion exchange resin layer or adding an ion exchange resin and agitating the mixture before filtrating it. Thereby alkali metal in the silicate solution is removed and acidic silicic acid solution whose alkali metal concentration is markedly decreased as mentioned above is obtained. Next, a small quantity of an alkalizing agent is added to the solution to correct the pH value to around neutrality and the limiting velocity and the SiO2 concentration are adjusted so that they have the above-mentioned values, respectively.

IPC: H04N5/369
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To improve the incident efficiency of a light by efficiently making a light having an angle with an optical axis incident on a light receiving picture element. SOLUTION: Almost semi-spherical microlens 19 and 20 on which inclined faces 19a and 20a are formed are formed on the light incident face of a solid image pickup element 12 corresponding to each light receiving element 12a. Also, inclination angle θ1 and θ2 of each inclined face 19a and 20a is gradually made smaller toward a peripheral side from an optical axis O side.  Therefore, an inclined light having an inclination angle more than a prescribed angle ϕ1 and less than a specific angle ϕ2 with the optical axis O can be fetched from an inclined face 19a of the microlens 19 at the optical axial O side, reflected, and converged on the corresponding light receiving element 12a, and an inclined light with an angle more than the specific angle ϕ2 with the optical axis O can be fetched from the inclined face 20a of the microlens 20 at the peripheral side, reflected on a spherical face 20b in the microlens 20, and made incident on the corresponding light receiving picture element 12a. Thus, a light crossing the optical axis O can be efficiently made incident on the light receiving face 12a.
