Title: Optical switch
Inventor: TSUKAMOTO MAKOTO
IPC: G02B26/08
Filed: 1981-06-29
Abstract: PURPOSE:To reduce deterioration in optical transmission characteristics based upon repetitive inflection of optical fiber in an optical switch which moves the optical fiber by using magnetic force, by covering the fiber to be moved with a magnetic metal. CONSTITUTION:When the contact of an optical switch 9 is connected to an S1, an electromagnet 11 turns on and a magnetic pole piece 8 atop of a light signal lead-in fiber 1 is attracted to a magnetic pole 6 to allow the tip of the optical fiber 1 to face an optical fiber 2 for leading out a light signal, which is guided through a route (a), (b), (c). When the contact of the switch 9 is changed over to an S2, an electromagnet 12 operates to allow the end surfaces of the optical fibers 1 and 3 to face with each other, and the light signal is guided through a route (a), (d), (e). The optical fiber 1 for optical path switching is covered with a magnetic metallic layer 22 (with 20-80mum thickness) of Fe, Co, Ni, etc., to provide an attracted part 23 with an about 1mm. external diameter, reducing deterioration in optical transmission characteristics based upon inflection of the optical fiber 1.

Title: Facsimile equipment with voice synthesis section for information
Inventor: OKANO HISASHI
IPC: H04N1/32
Filed: 1987-04-24
Abstract: PURPOSE:To improve the efficiency of a sender and to allow a receiver to acquire received data at a proper time by providing an information function telling the reception of a facsimile to the receiver by voice. CONSTITUTION:In case of transmission, an operator inputs an opposite receiver identification code and the facsimile number of the receiver side from an operation section 1. A facsimile function section 3 sends the opposite telephone number and the receiver identification code to a line 8 and transfers an original. The receiver side uses a receiver ID detection section 4 to detect the receiver identification code sent from the sender side. When the original is generated entirely, an information control section 5 extracts the telephone number of the receiver corresponding to the receiver identification code inputted from the receiver ID detection section 4 from a receiver identification code and receiver telephone number table and outputs it to the line 8. A network control section 7, in detecting the arrival to the opposite party, informs the information control section 5, which starts a voice synthesis section 6 to output the receiver name corresponding to the receiver identification code and the transfer of the facsimile to said receiver to the line 8 in a synthesized voice.

CONSTITUTION: In the blowing the pulverized coal into the blast furnace, at the time of ordinary operation, the pulverized coal 7 is passed through the inner pipe 6 of the double pipe lance 4 and blown in a tuyere 1 and a blow pipe 3. The oxygen is flowed in the outer pipe 5 of the lance 4. Successively, the blasting reduction is started in the blasting-stop preparing period. An oxygen stop valve is closed and an air stop valve 10 is opened through a stop valve control unit 17 to flow the air into the outer pipe 5 of the lance 4. When the blasting-stop preparing period completes, the blowing of the air into the outer pipe 5 is stopped. At the time of starting up the blasting, the air stop valve 10 is opened to flow the air into the outer pipe 5.  By this method, even if the plugging of the tuyere caused by the dropping of raw ore is developed, the erosion of the lance can be prevented.
