Title: Focus controlling method
Inventor: ABE MICHIHARU
IPC: G02B5/32
Filed: 1980-06-07
Abstract: PURPOSE: To obtain a lightweight, inexpensive device by using a diffraction grating as a means of giving astigmatism when reflected light from a flat reflective surface is made incident to a four-split photodetecting element.  
     CONSTITUTION: Linearly polarized light from a laser oscillator 1 is condensed on a flat reflective surface 6 by way of a beam splitter 3, a quarter-wavelength plate 4 and a condenser lens 5. Its reflected light travels backward, and is reflected by the beam splitter 3 and then diffracted by a plane diffraction grating 18. A four-split photodetecting element 19 is located near the crossover point of primary diffracted light. When the focusing point of the laser light is on the surface 6, the pattern of the light beam on the photodetecting element 19 is circular and when it shifts from the surface 6, the pattern is elliptic, so focus control is exercised on the basis of the difference output between the sums of outputs of two couples of facing photodetection areas. Thus, a lightweight, inexpensive device is realized.

Title: Manufacture of field shielding material
Inventor: HASEGAWA YOZO
IPC: B32B7/02
Filed: 1988-03-30
Abstract: PURPOSE:To increase the density of hot-pressed mixed paper and impregnated paper through compression, and to unify the mixed paper and the impregnated paper firmly by superposing the impregnated paper impregnated with a thermosetting resin onto the surface of the mixed paper, in which thermosoftening synthetic resin pulp and metallic powder are mixed, and hot-pressing both the mixed paper and the impregnated paper. CONSTITUTION:Impregnated paper 2 is obtained by printing a pattern having high designing properties such as the grain is printed onto titanium paper of basic weight of 55-160g/m<2> and impregnating the titanium paper with a thermosetting resin such as melamine and drying the paper, and mixed paper 3 is acquired by mixing metallic powder with thermosoftening synthetic resin pulp such as polyethylene and polypropylene. The thermosoftening synthetic resin pulp is used because metallic powder is held and the pulp is softened on hot-pressing. Mixed paper 3 is compressed when these pulp and impregnated paper are hot-pressed, and heat and pressure are applied so that the density of the mixed paper 3 is increased by 20% or more. Accordingly, the shielding effect of an electrostatic field and a dynamic electric field is improved, and an electromagnetic wave can also be attenuated, thus acquiring a decorative board, in which bonding among each material is strengthened and which has superior designing properties.

Title: Aeration device
IPC: C02F3/22
Filed: 1992-03-31
Abstract: PURPOSE:To save power and maintenance cost and cut equipment cost so as to contribute toward water purification by aerating water in a water reservior for a close supply system using a nearby existing energy source without the use of a new power source, if water needs to be purified in such a reservior. CONSTITUTION:Ejector nozzles 4-1 to 4-4 aspirate air through an air aspiration pipe and eject a jet stream containing air bubbles and further supply oxygen by feeding a pressurized water to the ejector nozzles 4-1 to 4-4 from a pump 2. Thus a vortex is generated in a storage tank 1 to replace a bottom layer water with a surface layer water and further supply oxygen. Consequently, poisonous gas such as H2S, NH3 is released into an atmosphere from the bottom by the circulating stream and instead, oxygen is supplied to the bottom. Following the above process, an accumulated waste is oxygen-decomposed by microbes to contribute toward an increase in animal planktons and bottom creature. In addition, the oxygen allows the bottom creature or fish to live at the bottom and resultantly a plant chain system to recover its balance. In this way, it is possible to improve the water quality.

Title: Method for knowing sound pressure in three-dimensional sound field
Inventor: HIRATA HARUHIKO
IPC: G01H17/00
Filed: 1987-04-01
Abstract: PURPOSE:To efficiently perform calculation, by dividing a linear sound source having a cross-sectional dimension smaller than the wavelength of sound into cylindrical elements having almost linear vibration speed distribution when the sound pressure of a three-dimensional sound field is calculated by a boundary element method to calculate the sound pressure by operation and integration. CONSTITUTION:Each of cylindrical elements 1 is a vibrating rigid cylinder having a finite length being a linear sound source having a cross-sectional dimension smaller than the wavelength of sound and capable of neglecting the scattering of sound. For example, the piping 3 connected to the compressor of a refrigerator is divided into elements having almost linear vibration speed distribution by surfaces S1, S2... to form a plurality of the cylindrical elements 1. Complex vibration vectors V1a, V1b and V2a, V2b in known arbitrary directions are applied to both ends of 1a, 1b of each cylindrical element 1. The scattering of the sound from the cylindrical element 1 is neglected to calculate the surface vibration speed of the cylindrical element 1. This vibration speed is integrated over each section of the piping 3 to calculate the sound pressure of a three-dimensional sound field. By this method, the sound field is efficiently calculated and accuracy is enhanced.

Abstract: PROBLEM TO BE SOLVED: To eliminate abnormal and unstable operations in a drive part of an electric stapler by transmitting a vertical drive force converting the drive force of a motor by a lever via a spring and raising/lowering a hammer between a paper binding position and a standby position. SOLUTION: When binding paper sheets are pushed into a switch lever 19 with their contacted therewith, a motor is rotated so that a rod 6 is driven by a boss 4 in a drive gear 3 in the last stage, a shaft 9 provided in the other end of the rod part 6 pushes a compression spring 11 with a fulcrum 8 set to the axis, and a hammer 10 is lowered. Therefore, a staple stored between a staple case outer frame 14 and a staple case 13 is pushed down by a staple presser spring 12 so that the staple penetrates through the binding paper sheets and bent against the staple bending part of a clamp. After that, the shaft 9 is raised by the rotation of the drive gear 3 to raise the hammer 10 and a micro-switch 28 is turned off to stop the rotation of the motor. The staple case 13 is returned to its original position by a spring 17.

Title: Optical sensor using superconductor
Inventor: TAKEMURA YASUHIKO
IPC: H01L39/00
Filed: 1990-03-27
Abstract: PURPOSE:To produce the superconducting optical sensor which has sufficient reliability and excellent mass productivity by measuring a change in the Q value of a cavity from a change in the resistance of the surface of an oxide superconductor when the surface of the oxide superconductor formed in the cavity via a window is irradiated with light, thereby sensing light. CONSTITUTION:If Maxwell equation is solved under adequate boundary conditions, 25% of the loss of the cavity 1 takes place at the terminal of the cavity 1. The inverse number, 1/Qs of Q of a sample (thin film 2 of the oxide superconductor 2) is determined by subtracting the inverse number, 1/Qc, of the empty cavity 1 from the inverse number, 1/Qc+s, of Q of the cavity 1 contg. the sample. Since the superconductor is utilized, the response speed to light is extremely fast (50ps) and the sensitivity is high. In addition, the detection of IR light is possible. The detection over an extremely wide wavelength region is possible as compared with conventional detectors for visible light and IR light for which the semiconductors are used.
