Title: Production of stationary light attenuator
Inventor: KURODA KENICHI
IPC: G02B5/00
Filed: 1979-02-16
Abstract: PURPOSE:To obtain the light stationary attenuator having no effect of reflection on metal film by installing two optical fibers parallel, fixing them by epoxy resin and cutting the same diagonally then forming a metal film on one cut face and bonding the respective cut faces. CONSTITUTION:Two optical fibers 1, 2 are installed parallel and are fixed by means of epoxy resin 4. If these are cut diagonally with respect to the optical fibers 1, 2 like a cut face 5, then the end faces of the optical fibers 1, 2 may be readily cut at the same angle. After the polishing, a metal film is formed on the end face of one optical fiber and the both end faces are bonded. When, with the light stationary attenuator made in this way, light is entered from the optical fiber 1 into the optical fiber 2, the light reflected by the metal film 3 is prevented from entering the optical fiber 1 again and propagating in the optical fiber 1. Hence, by changing the film thickness of the metal film 3 suitably, the specified attenuation amount may be obtained without the effect of reflection on the metal film 3.

Title: Frame synchronization monitor circuit
Inventor: SUGA SEIICHI
IPC: H04J3/06
Filed: 1990-01-29
Abstract: PURPOSE:To attain validity and invalidity processing of a CRC function automatically by providing a CRC invalidating section invalidating the operation of an error notice section when an output state of a frame synchronization acknowledge signal has dispersion for a prescribed number of times within a prescribed time. CONSTITUTION:The retrieval by a CRC frame synchronization information retrieval section 2 is failed because relevant synchronization information is not included in a PCM data string while being opposite to a PCM communication equipment without a CRC function and the output state of a frame synchronization acknowledge signal has dispersion. In this case, a CRC invalidating processing signal generating section 5 is started on the condition that the appearance of a PCM data is detected by a PCM data detection section 6 and when a prescribed number of times of dispersion is generated and detected in the output state of the frame synchronization acknowledge signal from a frame synchronizing signal retrieval section 1 within a prescribed time from the start, a high level signal is outputted. As a result, an output of an AND gate 4 is fixed to a low level and the passing of an error notice signal is blocked and the CRC function is invalidated. Thus, the invalidating and validating processing of the CRC function are implemented automatically and a troublesome job is eliminat ed.

IPC: C21B5/00
Filed: 1981-02-10
Abstract: PURPOSE:To control the distributions of charging materials at the furnace top in such a way as to meet the purposes of operations in a bell type charging method by dividing the ore charging after coke charging to the 1st and 2nd charging, and changing the dividing ratios of the rate of the 1st charging and the  rate of the 2nd charging. CONSTITUTION:In a bell type charging method of a blast furnace, the dividing ratio of charging of ore is determined from the relation with the rate of flowing- in of coke by the falling impact of ore during charging of the ore. More spcifically, the rate of flowing-in of coke layers increases as the rate of charging of the ore increases. In accordance with this finding, the ore charging after the coke charging is divided to the 1st charging and the 2nd charging. Thereupon, the dividing ratio of the 1st charging and the 2nd charging is changed so that the distributions of the charging materials at the blast top are matched to the purpose of operations.

Abstract: PROBLEM TO BE SOLVED: To provide a substrate made of resin enabling a clearance between its substrate body and a different substrate, etc., to be lessened when the substrate made of resin having many pins as input/output terminals erected thereon is mounted in a socket or on the different substrate., etc. SOLUTION: This substrate 1 made of resin is made up by soldering a pin 11 having an Au plating layer formed on a surface thereof, with a solder material 15 made of Sn and Sb, to a substrate body 2 made of resin or of a composite material including resin, formed substantially into a plate shape, and having a first principal plane 2A, and causing the pin 11 to project from the first principal plane 2A of the substrate body 2.  Because the wettability of the solder material 15 for fastening the pin 11 to the substrate body 2 is lower than that of a Pb-Sn solder material, the height of the solder material 15 creeping up the pin 11 becomes lower, The pin 11 can be sufficiently inserted into the interior of a socket ST, therefore a gap between the first principal plane 2A of the substrate body 2 and an upper surface STA of the socket ST can be lessened and the total height can be lowered when the substrate 1 made of resin is mounted in the socket ST.
