摘要:
A method of operating a blast furnace enables substantial improvement of gas permeability and liquid permeability for stable operation of the blast furnace, involves packing the core section with solid high strength, carbonaceous blocks prior to ignition of the furnace. The carbon blocks resist wearing and high temperature reaction over very long periods of operating time, greatly stabilizing the furnace. Because of the improved stabilization, gas permeability and liquid permeability, a low grade solid reducing agent can be substituted for a quantity of the high quality coke normally used for operating the blast furnace and furthermore enables injection of pulverized coal at a rate of at least 200 Kg/ton-pig.

A reinforced rubber hose mainly consisting of a hose body composed of inner and outer rubber layers and a reinforcing layer interposed therebetween and adapted to be secured or fastened at its two ends to a pair of cylindrical mouth pieces to be connected to the associated pipe ends. At least free end of the reinforcing layer is composed of inner and outer reinforcing layers. The inner reinforcing layer is wound around a clamping ring arranged at each end of the hose body from its inside toward the outside thereof to form a turn-back portion and the outer reinforcing layer is superimposed about and covering the turn-back portion of the inner reinforcing layer.

摘要:
An apparatus and method for preventing an interruption of electrical power to a portable electronic device, such as, for example, a call device, supplied by an internal battery when the portable electronic device is dropped or subjected to an external shock. A battery cover seals a battery compartment in which a negative battery terminal and a positive battery terminal, of a battery, are in contact with a respective compressible contact terminal and a fixed terminal. A battery fixing base plate, attached to an inner surface of the battery cover, includes a set flange that is inserted between a battery compartment wall to which one contact terminal is attached and an associated battery terminal in contact with the one contact terminal, thus providing a mechanism that prevents a longitudinal movement of the battery in the battery compartment.

A light-emitting element is supported by hooking claw sections at tip sections of a pair of supporting arm sections onto a top surface of the flange section, and a lower section of a basic body of the light-emitting element is pressed by a tip section of an elastic member to energize the light-emitting section upward. The light-emitting section raised upward by the elastic member is positionally restricted by hooking claw sections of a pair of supporting arm sections on a flange section, thus height of the light-emitting element on a substrate being maintained at a constant level.
摘要:
A protector block is movable in a direction in which a key K can be inserted, and first engaging portions which engage each other when the protector block is pushed in are formed between the protector block and an outer lock cylinder. A crankshaft is movable in the direction in which the key K can be inserted, and second engaging portions which engage each other when the crankshaft is pushed in are formed between the crankshaft and the outer lock cylinder. When an object in place of a key is inserted into a key insertion hole and attempts are made to forcibly turn the object while pushing the object, the first engaging portions between the protector block and the outer lock cylinder engage each other, preventing the crankshaft from being turned. When attempts are made to turn an inserted object while pulling the object, the second engaging portions between the crankshaft and the outer lock cylinder engage each other, preventing the crankshaft from being turned. In combination with tumblers preventing the crankshaft from being turned, the above structure makes it highly difficult to unlock the handle lock device.
