Title: Teletext receiver
Inventor: KOJIMA YUICHI
IPC: H04N7/025
Filed: 1990-05-16
Abstract: PURPOSE:To read out a sentence including external characters correctly by providing an external processing section converting an external character into other character string than the external character to a teletext receiver able to sound out an output. CONSTITUTION:An external character code detection section 10 checks the presence of an external character code in a data sent from a sentence segmentation section 9 and when an external character code exists, the external character code is sent to an external character code conversion section 23, which receives a character string for external character conversion and gives a sentence after conversion to a syntax section 11. The external character code conversion section 23 seeks a character string for the external character conversion from an external character conversion table 22 based on the external character code sent from the external character code detection section 10 and sends it back to the external character code detection section 10. The syntax section 11 applies syntax while using a dictionary based on a sentence received from the external character code detection section 10 and sends phoneme information and rhythm information to a voice synthesis section 12. The voice synthesis section 12 selects a phoneme from a phoneme dictionary, links the phonemes sequentially based on rules and a speaker 6 sounds the result.

Title: Tungusten material for welding structural body and its manufacturing method
Inventor: SHIMIZU TADASHI
IPC: H01J1/14
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a W material for a welding structural body which may be simply machined and welded, and hardly subjected to peeling and deformation while it is being annealed after welding by comprising the W material so that a specific quantity of thoria can uniformly be diffused and surface coarseness and tensile strength can be specified. CONSTITUTION:Thoria as a dope material specifies its particle diameter below 4mum by the workability of a W wire material and stability of a stable thermion emission material. When the quantity of compounding does not exceed 0.5wt%, thoria is poor in non-sagging property and weak in creep strength. Since the workability of the W wire material is deteriorated, when it exceeds 4.0wt%, 0.5-4.0wt% is occupied in the weight of W wire material. In addition, for the purpose of the stability of the thermion radiation characteristics, the surface coarseness of the W is restricted to 3mum or less and tensile strength is set to 170 to 245kg/mm.<2> considering the workability. As a result, the W material for a welding structural body with excellent resistance to deformation can be obtained.

Abstract: PURPOSE:To obtain a lead frame which has excellent corrosion resistance, excellent plating property and solderability by cladding Ni or Ni alloy in a base material made of Fe containing specific amount of Cr, specific amounts or less of C, Si, Mn, Al, and the residue of Fe. CONSTITUTION:A base material which contains by weight 5.0-10.5% of Cr, 0.10% or less of C, 2.0% or less of C, 2.0% or less of Si, 2.0% or less of 2.0, 0.10% or less of Al, and approximately the residue of Fe uses Ni- or Ni alloy- plated as a clad material 12. The Cr improves the plating property, heat resistance and corrosion resistance of the material. To obtain this effect, 5.0% or more is needed to be contained, if excess, it disturbs the plating property and solderability, and 10.5% or less is required. If the C is excess, the corrosion resistance and the solderability are deteriorated, and if the Si is excess, the solderability of the material is disturbed, the toughness of the material is disturbed. If the Mn is excess, the roughness of the material is deteriorated, and if the Al is excess, the solderability is disturbed, and the contents are required to be the above amounts or less.

Inventor: TAKAKADO YUZO
IPC: H02J3/18
Filed: 1994-05-17
Abstract: PURPOSE:To provide a reactive-power compensation device in which reactive power at a receiving end can be set arbitrarily. CONSTITUTION:A reactive current (an amplitude value) ILd which flows in a load 10 is found by three-phase/two-phase converters 2, 3 and a reactive- current detector 6. In addition, a reactive current which is generated by an inverter 9 is set by a reactive-current instruction value Id* which is output by an adder 17. When a switch 22 is turned off and a switch 23 is turned on, the load reactive current I is used as the reactive-current instruction value I as it is. On the other hand, when the switch 22 is turned on, the reactive- current instruction value Id* can be changed also by the amplitude V of receiving-end three-phase voltages VLU, VLV, VLW. When the reactive-current instruction value Id* is set properly in this manner, the reactive current (reactive power) which is generated by the inverter 9 can be set arbitrarily.
