Title: Measuring instrument for reflection factor
Inventor: HIYAKUMURA KAZUJI
IPC: G01N21/55
Filed: 1985-04-25
Abstract: PURPOSE:To obtain a reflection factor measuring instrument which is tolerant to noise and takes a high-accuracy measurement by using ring-shaped luminous flux and increasing the quantity of measuring light sufficiently. CONSTITUTION:luminous flux emitted by a light source 20 is made into the ring-shaped luminous flux through the ring opening 23 of a ring aperture stop 22 and the luminous flux is converged on an aperture stop 26 through a relay lens 24 and then reduced into a fine light spot through a pinhole 25. Luminous flux from the pinhole 25 is made into parallel ring-shaped luminous flux through a relay lens 27 and the luminous flux is reflected by a half-mirror 30 and converged on a surface 29 to be detected through an objective 28. Reflected light from the object surface 29 is made into parallel ring-shaped luminous flux by the objective 28, and the luminous flux is passed through the half-mirror 30, converged on an aperture stop 32 through a condenser lens 31, and incident on a photosensitive element 33 through a pinhole 31. This optical system uses the ring-shaped luminous flux, so the quantity of measuring light is increased.

Title: Dust cap for speaker
Inventor: INOUE TOSHIHIDE
IPC: H04R9/02
Filed: 1990-04-03
Abstract: PURPOSE:To make high stiffness and large internal loss compatible with each other by using a compound of liquid crystal high polymer fibers and thermoplastic synthetic resin fibers. CONSTITUTION:A dust cap is made of liquid crystal high polymer fibers and thermoplastic synthetic resin fibers and the liquid crystal high polymer fibers are linked and made composite by the molten thermoplastic synthetic resin fibers at heat molding. Since the density (rho) of the liquid crystal high polymer fibers is small and its tensile strength is large and its melting point is high, then the liquid crystal high polymer fibers are stable thermally, and the fibers have fibril structure, the internal loss (tandelta) of the fibers themselves is large. When the liquid crystal high polymer fibers are made composite by the molten thermoplastic synthetic resin fibers, the liquid crystal high polymer fibers are uniformly dispersed in the composite, and the density (rho) of the composite is small and the tandelta is high. Thus, high stiffness and large internal loss are made compatible in the dust cap.

Title: Electric blower
Inventor: SHIMADA SADAHIRO
IPC: F04D29/30
Filed: 1989-04-10
Abstract: PURPOSE:To pass air through a connecting path when the amount of air flow is small so as to eliminate unbalance of air flow and reduce vibration and noise by drilling the connecting path from the upper surface of a blade to the lower surface of it near the outer periphery of a fan comprising blades. CONSTITUTION:When a fan 14 is rotated by a motor 11 through a shaft 13, air is sucked from the opening 15a of a fan 15 into the suction port 14a of a fan 14 and exhausted through the interior of the fan 14 out of a delivery port 14e on the periphery of the fan. In the interior of the fan 14, air is forced out along the surface of a blade in the outer periphery direction by the blade 14b as fan 14 is rotated. In this case, when air flow passing through the interior of the fan 14 is reduced and becomes uneven, it passes through a connecting path 14f drilled slant in a blade 14b and blows from the pressure surface of the blade 14b into the basck side of it. Therefore, the fan 14 can be held in good balance. Thus, unbalance of the fan 14 can be eliminated to reduce rotational vibration and noise.

Filed: 1982-05-28
Abstract: PURPOSE:To shorten the rising time of gas laser output and eliminate fluctuation of gas laser output due to fluctuation of environmental temperature by providing a gas reservoir temperature control apparatus which makes temperature of gas reservoir equal to the temperature of discharge space. CONSTITUTION:The gas reservoir of hermetically sealed laser tube 2 is connected to discharge space in the tube through the connecting tube 3. Therefore, pressure in this system is always equal. In the not discharging condition, temperature of laser tube as a whole is equal and therefore density of particles is uniform and relation no/Vo= nds/Vd=nro/Vr can be obtained. (In this equation, no, ndo, nro are number of particles in the laser tube, discharge space and gas reservoir; Vo, Vd, Vr are volumes of laser tube, discharge space, gas reservoir.) On the other hand, in the discharging condition, temperature of discharging space rises and particle density is expressed as nd1/Vd=(nr1/ Vr)X(Tr1/Td1). (In this equation, nd1, nr1 are particle densities in the discharge space and gas reservoir during discharging; Td1, Tr1 are temperatures of discharge space and gas reservoir during discharging). Here, temperature Td1 is controlled to become equal to Tr1 using the gas reservoir temperature control apparatus. Therefore, nd1/Vd= nr1/Vr=no/Vo. Namely, particle density is always made equal and therefore rising time of laser output can be shortened and laser output fluctuation can be eliminated.
