Title: Production of optical transmission line
Inventor: SHIRAISHI SATOSHI
IPC: C03B37/012
Filed: 1979-04-09
Abstract: PURPOSE:To provide a high-productivity preparation of optical transmission line having dense sectional area and desired refractive index distribution by a method wherein a glass tube internal surface is formed with layer whose optical property is different from the glass tube, heated to form into a rod, then is spinned into fiber form. CONSTITUTION:The internal surface of a transparent glass material tube 5 is smoothed, on which a glassy deposited layer 6 whose optical property is different from the glass tube 5 is formed. This complex body is charged in a furnace 7 and is heated to about its melting temperature so that the center hollow section is closed to form into a rod. The formed rod has the deposited layer 6 whose density is higher than that of the outer glass. The rod is inserted into a second tube whose media 8, 9 have desired refractive index. This combination glass is heated in the furnace 7 and is spinned to form a fiber. The fiber, as required, undergoes heat treatment to enhance light transmissin.

IPC: H04L12/40
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To enable a slave using a data line to make a read request to a master when two-direction data transfer is performed by reducing the number of lines between the master and slave. SOLUTION: A slave is connected to a master through three lines for clock CL, data DT, and control signal CE. The AND output of a first flip flop(FF) which is set by a read request REQ to the master and a second FF which is set by a clock CL applied upon a bus drive connected to the data line DT and the second FF is reset from 'H' to 'L' in response to the level change of the control signal line CE. In addition, the read request is canceled when an output data mode is set by informing the read request to the master by resetting the second FF based on the input to an address for output mode from the master during the 'L' period of the line CE and, at the same time, temporarily inhibiting the read request until data transfer is completed.

Then the contacting impulse elements 36 and 37 are fitted to the fitting ring 34 and the resistance layers 42 and 44 are formed by carbon printing. Consequently, the film 49 which has the low friction coefficient is formed on the contacting surface of the substrate 40 where the end of the boss part 34 is pressed and slid, so the friction resistance becomes extremely small and the friction is reduced. The durability is therefore improved greatly.

Title: Protecting method for tuyere of bottom-blown refining furnace
Inventor: KOBAYASHI ISAO
IPC: C21C5/34
Filed: 1980-04-08
Abstract: PURPOSE:To protect the tuyere securely and enhance the durability of the tuyere by a method wherein a protecting material is blown in together with a carrier gas and is coagulated at the periphery of the tuyere, in the bottom-blown refining furnace. CONSTITUTION:The tuyere 13 of double-pipe structure consisting of an outer pipe 11 and an inner pipe 12 is provided at the bottom part of a vessel of the bottom- blown refining furnace. Oxygen gas for refining is blown in through the inner pipe 12, while the particulate protecting material 14 is blown in through the outer pipe 11 by using the carrier gas and is coagulated to form a protecting member 14' at the periphery of the tuyere. Alternatively, the tuyere is comprised of a single pipe and the protecting material is injected into the flow of oxygen gas. The protecting member 14' formed by said method is rigid and protects the tuyere securely. Incidentally, since the protecting member 14' is not formed on the inner side of the tuyere, the effective inside diameter of the tuyere is prevented from being changed. Accordingly, a reduction in the activity rate of the refining furnace due to replacement of the tuyere is avoided and the productivity is enhanced.

Title: Semiconductor pulse generator
Inventor: MITA AKIRA
IPC: H01L29/80
Filed: 1979-04-16
Abstract: PURPOSE:To enable generation of light pulse train having high speed and sharpness by integrally forming a light oscillator and a FET through a light waveguide on a monocrystal line substrate to effectively create the modulating action. CONSTITUTION:Both the FET position 11 and the light oscillator position 12 are located at 1/4 of the end surface 14 and 15, respectively of a light waveguide. When the FET is operated at special frequency, a gate is optically opened when the FET is on, the carrier density of the light oscillator is increased, so that the amplified light pulse locus 13 is reciprocated at a period of four times of the excitation signal period between the ends 14 and 15. Since three types of light pulses 16a-16c displaced in phase can be existed at this time, an external output light pulse finally has the same frequency as the modulation frequency. Thus, the positional relationship between the light oscillator and the FET is so located that the modulating operations of both the light oscillator and the FET are superimposed within the distance for coupling the end surfaces of the light waveguide.
