Abstract: PURPOSE:To produce a composite material having high strength and stable characteristics, such as fracture-resistant toughness, by preparing a composition as starting material consisting of ceramic raw material, such as oxide, oxides of group IVa elements, etc., carbon, etc., sintering the above composition, and allowing metal carbide to dispersedly precipitate in ceramics. CONSTITUTION:A composition as starting material which consists of a ceramic raw material (Al2O3, Si3N4, etc.) consisting of at least one kind among oxides, nitrides, and nitrogen oxides, the oxides (TiO, VO, Cr2O3, etc.) of the group IVa-VIa elements of the periodic table or/and the precursors (TiZrO, etc.) of the above oxides, and carbon or/and organic substance (carbon black, etc.) forming carbon by thermal decomposition is prepared. The above composition is sintered in vacuum or in a nonoxidizing atmosphere at about 1500-2000 deg.C, by which metal carbide is precipitated and dispersed in ceramics as matrix so that the volume ratio of the matrix to the metal carbide is regulated to about 95:5-50:50. By this method, the composite material reduced in the dispersion of sintered-compact characteristics is produced.

Title: Manufacture of niobium-titanium alloy superconducting wire
Inventor: SUZUKI TAKUYA
IPC: B21F19/00
Filed: 1990-02-13
Abstract: PURPOSE:To make manufacturing of a superconductor efficient by contracting a diameter of an Nb-Ti alloy ingot, which is melted and cast, by hot/cold processing so as to make it into a bar-shaped body, applying homogenization heat treatment, cutting the bar-shaped body, the bundling many bar-shaped bodies, coating the periphery with Nb or Ta, inserting it into a pure copper pipe, and extruding it, after sealing it in vacuum, so as to elongate it. CONSTITUTION:It is effective to apply a surface reduction process to contract a diameter and then apply homogenization treatment to it, since it is difficult from the point of diffusion distance between atoms to homogenize an Nb-Ti alloy ingot as it is. Usually most of melted Nb-Ti alloy ingots are about 500mmphi, and homogenization treatment is extremely difficult. Therefore, the homogenization is made relatively easy by applying homogenization treatment after processing the surface to be reduced to obtain a bar-shaped body of about 10mm. Moreover, as a secondary effect, if we bundle many Nb-Ti bars of small diameters and perform surface reduction processing such as extrusion, drawing out or the like, junction interface acts as a pin stopping point, and critical current density is also improved.

In addition, the formation of the PTFE layer 12 containing the adsorbent and the PTFE layer 11 containing the photocatalyst is repeated a required number of times to manufacture a multilayer sheet. Finally, this multilayer sheet is peeled off the metal foil and then is orientated by a factor of about 2-5 times into a porous texture. This, the sheet 1 for cleaning is obtained.

Title: Remote control system
Inventor: MATSUSHITA HITOSHI
IPC: H04B14/08
Filed: 1984-02-24
Abstract: PURPOSE:To attain remote control of a reception part despite the existence of an opaque obstacle by using radio waves to radiate the remote control modulation signal which is obtained by modulating a carrier of an SCA frequency band with a code signal for remote control and by means of an IC for transmission. CONSTITUTION:An IC17 for reception demodulates a remote control modulation signal and produces a code signal for remote control to apply it to an analog switch 25. This switch 25 switches a carrier of 76kHz with said code signal and produces the remote control modulation signal. This control signal is synthesized with a stereophonic synthetic signal by a resistance 26 and transmitted to a reception part after subjecting to the FM modulation through an FM transmitter 29. The reception part receives the FM radio wave and demodulates both the original stereo synthetic signal and the remote control modulation signal through a high frequency amplifier 40, a mixer 41, a local oscillator 42, an intermediate frequency amplifier 43 and an FM demodulator 44 respectively.

Title: Zoom lens with hand shake correcting function
Inventor: HAYASHI KOTARO
IPC: G02B13/18
Filed: 1994-03-03
Abstract: PURPOSE:To lessen the generation of magnification chromatic aberration by composing a zoom lens of a first group including a movable hand shake correcting optical system and an immobile negative lens for correcting hand-shake, a second group having a positive power and a third group having a negative power. CONSTITUTION:In order from the object side, this zoom lens is composed of a first group Gr1 composed of an almost plano-convex positive lens CL1 whose convex surface confront the object side, a negative meniscus lens LN whose concave face confronts the image side and a positive meniscus lens L4 whose convex face confronts the object side, a second group Gr2 composed of the joined lens of a negative meniscus lens having concave face on the image side and a positive meniscus lens having convex face on the object side, a light-beam limiting plate S, the joined lens of a negative meniscus lens having concave face on the image side and a bi-convex positive lens and a diaphragm A, and a third group Gr3 composed of a positive meniscus lens having a convex face on the image side and a negative meniscus lens having a concave face on the object side. In this case, since magnified chromatic aberration generated in the second and the third groups is canceled owing to the dispersion of the negative lens, its generation is suppressed to be little even at the time of hand shake correction.

Abstract: PURPOSE:To obtain an inexpensive AD converter with fast converting speed by using an output of a reference voltage generating source generating plural reference voltages as a reference input of each block and using an analog input as a comparator input of the 1st stage block. CONSTITUTION:A comparison input X and a reference input Y are inputted to a comparator 1 and a subtractor 2, the comparator 1 compares the quantity of the X and Y and the subtractor 2 applies subtraction of (X-Y).

Then similar operations are applied up to the final stage block 8. The speed of the AD conversion is the sum of processing speeds of each basic circuit block and the processing speed of the basic circuit block depends on the comparator 1 or the subtractor 2, operated more slowly, and the switch 3. Thus, the converting speed is quickened very fast.

Abstract: PURPOSE:To lower the temperature of a seat surface and improve the durability by providing a groove in the connection of a valve body and a seat member and fixing an adiabatic material to this groove with the outside surface bearing against the seat member. CONSTITUTION:A valve body 1 is provided with a seat member 2 forming a seat surface 10 for a valve seat. In this case, the valve body 1 is formed on the outer peripheral portion with a groove 1a in which is fitted an adiabatic material 3 having small grooves 6 on the inner and outer surfaces. And the adiabatic material 3 is connected to the valve body 1 through a wax material 4b filled in the groove 6. Also, the valve body 1 is bonded to the seat member 2 by wax 4a. Thus, heat transmitted from a fire contacting surface 5 of mushroom valve is almost insulated by the adiabatic material 3, and the seat surface 10 has heat taken away by the valve seat so that the temperature rise of the seat surface can be restrained low, and thus the durability of the mushroom valve can be improved.
