Abstract: A wishbone type suspension system for a motor vehicle comprises upper and lower suspension arms each having one end pin-connected to the body of the motor vehicle and a knuckle member operatively connected to an axle of a wheel of the motor vehicle. The suspension system further comprises a connecting rod having one end connected to an intermediate part of one of the suspension arms and a bell crank lever having a first end pin-connected to the other end of the connecting rod, a second end pin-connected to one end of the knuckle member and a bent portion between these first and second ends. The bent portion is pin-connected to the other end of the other one of the suspension arms.

Abstract: An apparatus for polishing end faces of optical fibers so that they are each given a convex spherical surface. The optical fibers are mounted on a jig so that their end faces are pressed against a polishing film attached to a rotary disk. The polishing film is made of a flexible (or cushionable) soft material having a Shore hardness of 10 through 100, such as synthetic rubber. The jig performs an orbital motion without rotation on its own axis.

Abstract: A disk cartridge shutter opening and closing mechanism which is disclosed herein is designed to open and close a shutter of a disk cartridge having a variety of disks contained in a shuttered hard case and is of a construction having a pair of arms swingably mounted within a range of a width of the disk cartridge, the arm having a block which is pivotally mounted on its leading end and integrally formed with an engage head portion and an arm portion which are used for opening and closing of the shutter. The pushing-in of the disk cartridge causes the pair of arms to be swung toward each other, thereby opening and closing the shutter. A smaller pushing-in force enables the shutter to be smoothly opened and closed. Moreover, the whole mechanism is thin and compact.

Abstract: An oil hydraulic clutch having opposite disks is provided in a power transmitting system. One of disks is operatively connected to one of side gears of the central differential through a gear train and the other of the disks is operatively connected to the other side gear of the central differential through another gear train, whereby torque is transmitted to front and rear wheels in a distribution ratio.

Abstract: An optical fiber connector according to the present invention is of the type in which optical fibers are inserted into a pair of ferrules which in turn are forcibly inserted into a sleeve so that the end surfaces of the optical fibers are in contact. The fiber misalignment, or disagreement of the centers of the optical fiber cores, may be corrected by relating a ferrule supporting plug while the ferrules are disposed in a sleeve adapter which holds the sleeve.

Abstract: A metal mold for resin molding of the type which comprises the combination of a fixed side metal mold assembly and a movable side metal mold assembly. Melt resin material is supplied into and filled in a cavity formed between the fixed side metal mold assembly and the movable side metal mold assembly, and pressure applied to obtain a desired mold thickness of a disk, etc. The metal mold for resin molding according to this invention further includes a spacer inserted between the ends of the guide post rods and the movable side metal mold assembly, to define a gap for adjusting the metal mold thickness.

Abstract: A novel process for preparing an ester of cyanoacetic acid which comprises reacting a cyanoacetaldehyde acetal, hydroxylamine and an alcohol.

Abstract: Composite powder coated with a noble metal is produced by adding a powder of a metal or alloy baser than the noble metal to a powder of a metallic sulfide, carbon, activated charcoal, metallic carbide, or metallic oxide, and then adding to the resulting mixture a solution containing the noble metal with stirring. The particles of the composite powder are coated with the noble metal that results from a cementation reaction.

Abstract: A multilayer-coated composite powder is produced by a first step of treating a core powder to be coated with first metallic ions and a metallic powder for reducing the first ions and thereby forming a single-layer coated powder, and a second step of treating the single-layer-coated powder with either only second metallic ions other than the first metallic ions or the second ions in the presence of a metallic powder for reducing the second ions. Where necessary, the second step is repeated the number of times required for forming a predetermined number of coating layers.

Abstract: A method for plating a powder with a metal by substitution, which comprises adding a crystalline powder of a metal chloride hydrate after and/or during mixing a powder to be plated and a reducing metal powder, and after the initiation of the reaction, adding water and/or hydrochloric acid.

Abstract: A drum type disc filter device for dehydrating paper pulp slurry. The drum and the disc filters are axial drain chambers and sector type filter members. Pressurized air is fed into the drain chambers sequentially when each drain chamber and corresponding filter members are at a predetermined angle of rotation of the drum. Paper guide plates are secured between the disc filters to guide separated paper pulp cakes safely into a chute without causing interference of lumping of the paper pulp cakes.

Abstract: A process for obtaining chlorine and iron oxide from iron chloride by adding iron oxide to iron chloride prepared by chlorinating iron-containing titanium ore, in an amount of above 10 percent by weight of the resulting mixture, charging the mixture in solid phase into a fluidizing roasting furnace for oxidizing roasting, extracting the overflow from the fluidized bed in the furnace, and charging the extract into another secondary furnace for additional oxidizing roasting. The iron oxide thus obtained is cooled and recycled to the fluidized bed in the primary fluidizing roasting furnace for the purpose of controlling the reaction temperature in the furnace.

Abstract: Various types of repeaters which are requisite in combination for making electrical networks such as CATV or MATV systems are unified into a common or universal repeater enabling three fundamental performances comprising a trunk line junction, a branching junction and a distributing junction each use of which is selectively determined by changing connective angles of two plugs containing a branching circuit and a distributing circuit, respectively.

Abstract: In producing slag ballast from molten slag obtained from metal smelting processes, molten slag is poured into a revolving cylinder which is supported in an inclined position, and the whole external peripheral surface of which serves as the cooling surface, and the molten slag is cooled at a rate exceeding 20.degree. C/min.As the molten slag is cooled while it moves forward in the revolving cylinder, it is broken up into medium sized lumps to become slag ballast.

Abstract: A process for preparing dialkyl oxalates by reacting an aliphatic alcohol with carbon monoxide and oxygen under pressure. In the present process, (a) a catalyst consisting of a mixture of a salt of a platinum group metal and a salt of copper or iron and (b) an accelerator composed of one or more compounds selected from the group consisting of carbonates, hydrogen carbonates, nitrates, sulfates, hydroxides and carboxylates of an alkali metal and of an alkaline earth metal, pyridine, quinoline, glycine, alanine, urea, thiourea, formamide, acetamide, acetylacetone, ethyl acetoacetate, dimethylglyoxime, a tertiary amine, and a substituted or unsubstituted triphenyl phosphine are both used.
