Abstract: An isobutylene is polymerized in the presence of an aromatic initiator and a catalyst under the conditions that either a chlorinated hydrocarbon or an aromatic hydrocarbon is used singly or in admixture with an aliphatic hydrocarbon so that the reaction solution has a dielectric constant of 1 to 5 and a solubility parameter of 7.5 to 9.0.

Abstract: A seesaw switch including a rigid member bridging first and second elastic click members, each elastic click member carrying a moveable contact positioned over a fixed contact. A lever is pivotably positioned over the rigid member and includes a first projection contacting the rigid member near the first elastic click member, and a second projection contacting the rigid member near the second elastic click member. When the lever is pivoted a first angular amount in a clockwise direction, the first projection presses against the rigid member, causing the rigid member to rotate with respect to the second elastic member to buckle the first elastic click member. Further pivoting of the lever in the clockwise direction causes the rigid member to rotate with respect to the buckled first elastic click member, thereby buckling the second elastic click member.

Abstract: A switch device comprising a first sliding switch operated by a first knob, a second sliding switch operated by a second knob, a connecting member for connecting the slider of the first sliding switch and the slider of the second sliding switch and a mechanism prohibiting operation of the second sliding switch when the first sliding switch is operated and conversely prohibiting operation of the first sliding switch when the second sliding switch is operated. With such an arrangement, the capacity of the electro-conductive network for power source which is shared by the two sliding switches in such a switch device can be significantly reduced and consequently the size and weight as well as the manufacturing cost of such a device can be considerably reduced. Such a switch device can be conveniently used for a power operated automobile seat.

The lever switch includes mounting the switch mechanisms for the first and second switch knobs around a portion of the rotational shaft, thereby allowing the rotational shaft to be shortened and the lever switch to be connected at an angle to the base.

Abstract: An automatic cancelling device for a winker is disclosed, in which a locking removing member can efficiently transmit a stroke of a working member of a solenoid when returning a holder to neutral position. Construction of the locking removing member includes an engaging portion that engages with the working member of the solenoid, a first fulcrum portion on one side of the locking removing member which is brought into contact with the holder, and a second fulcrum portion on the other side of the locking removing member which is brought into contact with a supporting portion located on the lower case. Further, engaging protruding portions, disposed on one side of the holder, slide upon cam portions disposed on the locking removing member on either side of the engaging portions. Hence, by using the construction above, the locking removing member is rotated around one of the fulcrum portions without rotation of the working member of the solenoid.

Abstract: A metal-making apparatus is suited for the production of molten iron from iron ore which is in a state of particles with a wide range in size. Included are a solid-state prereduction furnace for preliminarily reducing the raw ore particles in a solid state, and a smelting reduction furnace for smelting the prereduced ore particles and reducing them in a molten state. High temperature reducing gas generated within the smelting reduction furnace is directed into the prereduction furnace and blown up through a distributor on which there is loaded a charge of raw ore particles. The ore particles of larger size form a fluidized bed on the distributor and so are prereduced by making intimate contact with the gas. Ore particles of smaller size, on the other hand, are carried away from the fluidized bed by the waste gas and thereby prereduced while being recirculated through the prereduction furnace.
