Title: Rotary drum type continuous sand separating equipment
Inventor: ISHIDA AKIRA
IPC: B03B5/56
Filed: 1979-05-01
Abstract: PURPOSE: To separate perfectly and treat a large quantity of turbid water per unit time, by returning the settling sand to the filter plate side by the action of sand sending vanes along with rotation of a drum.  
     CONSTITUTION: When turbid water is supplied into a rotating drum main body 1 through a turbid water lead-in trough 14, the settling sand is sucked up by a filter plate 17 and drops on a conveyor 11, and is discharged out of the drum main body by continuous transfer of the conveyor 11 to be dumped onto a hopper 16. On the other hand, the water content flows towards an overflow port 10, and fine sand settling in this course is returned by the spiral action of sand sending vanes 20, and is transferred to the side of filter plate 17 by way of a communicating window 19 in a ring plate 18 and is sucked up again by the filter plate 17 to be dropped onto the conveyor 11. Then, only the supernatant flows out from the overflow port 10 into a discharge trough 24. Since water sending vanes 21 rotate in reverse spiral direction of the sand sending vanes 20, flow of supernatant into the side of overflow port 10 is accelerated.

Abstract: PURPOSE:To eliminate the adverse effect of a light leakage current for an EPROM or the like by providing means for shielding a P-N junction region from a light at a device for containing a semiconductor substrate in which the P-N junction is provided in a container having a light transmission window. CONSTITUTION:There exist a method of forming a light shielding layer capable of being laid at the stage of forming a pattern on a P-N junction region in which a light leakage current becomes a problem in the operation of a circuit and a method of forming a light shielding layer on the overall surface of the circuit region becoming a problem. When the drain junction region of an FET having a drain 421, a gate 46 and a source 422 is, for example, concerned, an aluminum wire 50 connected, for example, through an insulating film is so formed as to cover the overall surface of the junction, thereby shielding the light. Similarly, the light can also be shielded by employing a polysilicon film 52 interposed as a contacting layer between the wire 50 and the drain 421. A metallic film 72 is, for example, formed through a light transmission insulating film on the upper surface of a chip 60 in which an EPROM is, for example, formed, thereby shielding the light from the overall surface of a peripheral circuit region. The light leakage current can be eliminated by applying  solely or in combination the above methods.

Abstract: PURPOSE:To obtain an optical branching and demultiplexing circuit which is reduced in branching loss by forming >=2 branching optical waveguides on a substrate in a shape based upon a square-law cosine function. CONSTITUTION:The optical branching and multiplexing circuit is constituted of the substrate 1, a main waveguide 2 which is formed by a Ti diffusing method, the branching waveguides 3a and 4a which are formed by the Ti diffusing method as well to equal width, and a branching point 5a, and those main waveguide 2 and branching waveguides 3a and 4a are single-mode optical waveguides. Then the optical branching and multiplexing circuit is formed so that the shape of the part of the branching waveguides 3a and 4a shown by length L, i.e. what is called a Y branching part is based upon the square-law cosine function. Consequently, the inclination of the optical waveguides 3a and 4a in the vicinity of the branching (multiplexing) point is decreased gradually to zero and the inside refractive index can be made smaller than the outside refractive index in the vicinity of the branching point, so the inclination of the wave front of light can be controlled properly and the optical branching and demultiplexing circuit which is reduced in branching loss is obtained.

Abstract: PURPOSE:To obtain an inexpensive detector with high measurement precision by dividing object light and reference light into mutually pi/2 out-of-phase polarized components and causing each polarized component to interfere. CONSTITUTION:Light from a laser light source 40 is transmitted through beam splitters 41 and 42 and reflected by a mirror 43 fitted to the surface of a body to be measured, and further deflected by the splitter 42 to obtain the object light. Light reflected by the splitter 41, on the other hand, is deflected by a fixed mirror 44 and then passed through a quarter-wavelength plate 45 to obtain the reference light. This object light does not change in polarization state, but varies with optical path length according to the displacement of the object. The reference light is polarized circularly by the quarter-wavelength plate 45 into pi/2 out-of-phase components. Then, the object light and reference light are each split into two by a beam splitter 46, and respective polarized components are separated by two polarizers 47 and 48 which have planes of polarization at right angles to cause each component to interfere on two detectors 49 and 50.
