Title: Conductive grinding wheel at low cost and manufacture thereof
Inventor: MASUDA TSUNEO
IPC: B24D3/34
Filed: 1990-06-11
Abstract: PURPOSE:To aim at the large cost down, and obtain a conductive grinding wheel having the same performance as a conventional one by making silver and carbon co-exist in a communicating pore of a grinding wheel to form a conductor made of silver and carbon into a continuous net in the grinding wheel. CONSTITUTION:Heat reversible or thermosetting monomer or oligomer is filled from the surface of a grinding wheel 1 into communicating pores inside of the grinding wheel 1, and is heated, and after the polymer or the oligomer is polycondensed, the grinding wheel 1 is heated under the inert gas atmosphere or Co2 atmosphere to carbonize the polycondensed polymer or oligomer. Next, silver ion solution is impregnated to the grinding wheel 1 to be heated for dry. These processes are repeated to adhere silver in the communicating pores, and thereafter, the grinding wheel 1 is heated under the inert gas atmosphere or reduced pressure atmosphere to form a conductor made of metal silver and carbon into a continuous net form in the grinding wheel 1.

Abstract: PURPOSE: To adsorb and collect uranium in seawater, by a method wherein an adsorption agent is held in a net-rope structure which is in the sea near the sea level, and the sea water passes through the adsorption agent due to the movement of the seawater.  
     CONSTITUTION: A cubical space is formed in the sea with net partitions in a net- rope structure which consists mainly of synthetic fiber rope and synthetic fiber net, and an adsorption agent is placed in the surrounding space to form an adsorption bed. Edges of the net structure consists of tension ropes and shape-holding materials. Floating objects 5 are located at adequate intervals, and sinking objects 6 are hung down corresponding to the objects 5 by means of ropes. A transverse tension is held by the use of mooring cable 7 and concrete block type anchors 8 positioned at corners of the net unit structure. The adsorption agent on the adsorption bed repeates the movement in accordance with the period of the wave to perform the adsorption of uranium. The adsorption agent which has adsorbed uranium in seawater is lifted onto a ship, and operations such as washing, desorption, and concentration of uranium are performed in a factory on land to collect the uranium.

Abstract: PROBLEM TO BE SOLVED: To reduce a residual error after convergence without reducing the convergence speed of an adaptive filter by controlling a step size at the time of obtaining an N-dimensional tap weight vector so that it becomes almost equal to the value minimum in the square average error at that time. SOLUTION: For the N-dimensional tap weight vector c<(n)> at time (n), which is realized as a non-cyclic filter, a probability grade sine algorithm given by an expression I is used as an input signal series where αc <(n)> is set to be the step size at time (n), en to be an error signal series, νn to be a noise series, sgn to be a polarity function and a<(n)> to be time (n). A step size controller controlling the step size αc <(n)> in the expression I so that the square average error ε<(n)> at time (n), which is given by an expression II, becomes almost minimum is provided. Thus, the residual error after convergence is reduced and convergence can be speeded up.

Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized luminaire having enhanced efficiency. SOLUTION: A luminaire 1 is so formed that the flat surface 19 of a reflector 17 is made to abut against a lower lamp body 6 to store the reflector 17 to eliminate clearance between the reflector 17 and the lower lamp body 6. To replace a lamp 26, the lower lamp body 6 is opened relative to an upper lamp body 2 and the lamp 26 is installed/removed from an opening 5 in the upper lamp body 2. To close the opening 5 in the upper lamp body 2 by means of the lower lamp body 6, a cut 20 for the positioning stay of time reflector 17 is fitted over the positioning stay 12 of the lower lamp body 6 to achieve positioning.  The reflector 17 is pushed up against a spring 22 and the opening 5 in the upper lamp body 2 is closed by the lower lamp body 6 with the flat surface 19 of the reflector 17 abutting against the lower lamp body 6, so as to reduce the vertical size of the luminaire for thinning. Direct light from the lamp 26 and the light reflected from the reflector 17 are emitted downward via a glass pane 11 and do not enter between the upper lamp body 2 and the lower lamp body 6, and therefore a light distribution characteristic and luminaire efficiency are enhanced.

Title: Optical beam scanner
Inventor: NOGUCHI MASARU
IPC: G02B27/00
Filed: 1982-09-03
Abstract: PURPOSE:To realize a scanner, which has a high timing precision of scanning, at a low cost, by compensating the distortion of the speed of light spot scanning on a scan face by a photoelectric signal obtained by a rotatable grating pattern. CONSTITUTION:When an oscillatory mirror 1 is deflected from the deflection center at an angle theta/2, laser beams 8 and 9 are deflected from reference directions 15 and 15' at an angle theta. As scanning lenses 2 and 2', ftheta lenses having focal lengths (f) and f' are used, and a spot position (x) of the deflected beam 8 on a scan face 3 satisfies equation x=ftheta. A spot position x' of the deflected beam 9 on a grating pattern 5' satisfies equation x'=f'theta, and x/x'=f/f' is ture. Thus, spot positions (x) and x' have a proportional relation through a coefficient independent of the angle theta of polarization of beams. Consequently, when the grating pattern is constituted in a certain cycle and the light spot scanning the scan face 3 is timed by the modulation photoelectric signal of the grating pattern, the distortion of the scanning speed is compensated.

Abstract: PURPOSE:To utilize the heat of steam on the turbine output side in an arrangement where the steam from a boiler drives a turbine and the output steam from turbine is liquefied and fed back to the boiler, by drying solid material etc. with this heat which the output steam has got rid of. CONSTITUTION:Steam produced by a boiler 2 is introduced into two units of turbines 4 interlocked with a blower 12 and a power generator 6, respectively, and upon driving them is sent to a heating device 14 in the low temp. and low pressure state. Part of this low-temp., low-pressure steam is condensed by said heating device 14 to emit the latent heat, which is used to warm the material and fuel. The low-temp., low-pressure steam, part of which is condensed, is liquefied by a condenser 8 to be sent back to the boiler 2 by a water supply pump 10. Thus solid material and fuel can be dried up or preheated by said output steam from the turbine 4, which means that the heat of the low-temp., low- pressure steam from boiler 2 can be collected effectively.
