Title: Lance for blowing powdery raw material into converter
Inventor: KUROKI TAKASHI
IPC: F27D3/18
Filed: 1994-05-27
Abstract: PURPOSE:To provide a lance for blowing powdery raw material into a converter, resolving the problems, such that, as the hardness of the powdery raw material of chromium ore, etc., charged into the converter is high, a wear resistant material is lined on the inner wall surface of the blowing lance, but particularly the tip part of the lance develops remarkable wear because the flow speed of the raw material is fast, and thus, the service life is shortened, and further, the maintenance requires large labors. CONSTITUTION:A cylindrical wear resistant material 2 is arranged on the inner peripheral surface 1a at the tip end part of the metallic lance 1 so as to be attachable/detachable by screwing from the tip end part of the lance 1.

Filed: 1989-05-09
Abstract: PURPOSE:To make a dynamic damper smaller and lighter by installing plural mutually adjoining elastic members whose sections are opened frapezoid-shaped or inverted opened trapezoid-shaped between the outer periphery of a rotary shaft and an outside mass member. CONSTITUTION:Ring type mass members 11 are arranged coaxially at specified intervals, for example, from the outer periphery of a drive shaft for automobile and six elastic members 12, for example, are installed between both of them to fix its end with a fixed member. The mass member is a thick-wall steel pipe material coated with rubber or the like. In the elastic member, its one end is connected to the inner periphery of the mass member 11 and the other end is branched and has one end 122 coming into contact with the outer periphery of the drive shaft so that a space 12 may be generated. In the elastic member, the mass member is supported in a shearing direction against the vibration in the radial direction of a rotary shaft and a compression element is applied against distortion. It is thus possible to make a damper smaller and lighter.

Title: Base station for cordless telephone set
Inventor: YUZA MASAAKI
IPC: H04W72/04
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To use a physical slot effectively as a communication channel without the need for providing a special mobile station by stopping a logic control channel signal to a mobile station and using the physical slot as the communication channel instead. SOLUTION: In the case that a new 'link channel setup request' comes newly from a mobile station 11 to a base station 12 where a logic control channel is sent through one physical slot and the three remaining physical slots are used for communication channels, the base station 12 sends a 'link channel assignment' denoting that the physical slot having used for transmitting a logic control channel signal up to now is assigned to the mobile station 11 through an outgoing individual cell channel (SCCH) and stops the transmission of the logic control channel signal. Then synchronization burst signals are sent/received through the newly assigned physical slot as a communication channel to execute the usual setup procedure for the communication channel. In this state, the four physical slots of the base station 12 are used all for the communication channels.

Filed: 1981-07-24
Abstract: PURPOSE:To improve the safety of a water-wheel by applying a closed signal to a governor with a permanent magnet generator coupled directly to a generator shaft as a power source when a control DC power source in a station fails. CONSTITUTION:Since a DC failure detecting auxiliary relay 201 is energized when a control DC power source is present in a station, the movable coil 65c of an electrohydraulic controller 19 is normally controlled in regulation by the output signal of an operational amplifier 18. When the power source fails, the relay 201 is deenergized, a closed signal is applied to the coil 65c by the output of a permanent magnet generator 4 coupled directly to the generator shaft. Accordingly, the guide vane of the water wheel is closed. In this manner, even if the control DC power source in the station fails, the water-wheel can be safely operated.

Abstract: PURPOSE:To enable nonvisual retrieval in an early stage and to easily retrieve a defective circuit and a registered circuit by collating the connection states of circuit elements and terminals in a circuit to be retrieved with the connection states of each specific circuit. CONSTITUTION:All circuit elements and the connection points of terminals of mutually connected circuit elements are imparted with optional user set numbers, which are inputted from an input part 1 to generate a coordinate table. Then a CPU 2 converts the user set numbers into predetermined internal numbers in the order of terminals having larger electric features such as the directivity, etc., of the currents of the respective circuit elements. Further, the circuit elements are converted into element symbols determined by their kinds so as to facilitate collation between the circuit elements. Then a retrieval table wherein the circuit elements connected to the respective connection points are made to correspond in the order of the internal numbers is generated and stored in an external storage device 5. Thus, retrieval tables of many specific circuits are stored as respective records to constitute a data base which uses the internal numbers as retrieval keys.

IPC: C21C1/02
Filed: 1977-09-30
Abstract: PURPOSE:To enhance the desulfurization yield of CaC2 by mixing a CaC2 type dusulfurizing agent with a mixt. of Al ash and carbon as a desulfurization accelerator. CONSTITUTION:30-90wt% of finely divided CaC2 is mixed with 70-10wt% of a mixt. of Al ash and carbon. The Al ash is fine powder of 250mu or below contg. Al2O3, F2, etc. other than at least 60% of Al and the carbon is fixed carbon rich, finely divided coke, coal, graphite, etc. of 210mu or below. The mixing ratio of the Al ash:carbon is 90-65%:10-35%.

IPC: F02N11/08
Filed: 1977-09-30
Abstract: PURPOSE: To stop operation of starter and prevent rotation of the starter at an overspeed, by controlling a starter power source disconnecting circuit with the output of  a detection circuit for detecting the output level of a D-A converting circuit, which detection circuit is provided between the D-A converting circuit and starter disconnecting circuit.  
     CONSTITUTION: When the starter switch is turned ON, starter relay 3R is energized by the output of comparator COP and contact SW 1  is closed, whereby current is supplied to starter 4 and engine 1 is started. As rotational speed of engine 1 is increased, oscillation frequency of pulse generator 5 is also increased, whereby voltage of operational amplifier OP in D-A converting circuit 6 is amplified and supplied to level detector 8 and its output potential is raised. By this potential, output of comparator COP is reduced to zero, when the engine is rotated at a speed lower than the idling speed but higher than the minimum starting speed. As the result, current supply to starter disconnecting circuit 3 is stopped and operation of the starter is stopped
