Patent JP-H1197787-A (JP)
Title: Semiconductor laser controller
Inventor: EMA HIDETOSHI
IPC: H01S5/068
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To protect an integrated circuit or a semiconductor laser in safety against fluctuation of power supply voltage by ensuring turn off state of the semiconductor laser not only when the power supply voltage is low but also when it is high at the time of turn on power. SOLUTION: Since a start-up section 35 permits start of operation only when the power supply voltage is within a desired potential range, optical output of a semiconductor laser 1 is turned off not only before the power supply voltage reaches a desired potential level bur after the power supply voltage exceeds over the desired potential range at the time of turn on power. Since the semiconductor laser 1 enters into operating state only when the power supply voltage is within a desired potential range, the semiconductor laser 1 is protected against deterioration or damage and safety is enhanced by avoiding such a trouble as the semiconductor laser 1 emits light inadvertently.

Inventor: INOUE MASAMI
IPC: G02B6/40
Filed: 1987-10-16
Abstract: PURPOSE:To prevent the degradation in the opto-electric conversion efficiency of photodetecting elements by the shadow of bonding wires by bulging the bonding wires of the photodetecting elements, the surfaces of the photodetecting parts of which are drawn out toward the outside, to a loop shape atop the concentrical photodetecting elements. CONSTITUTION:Electrode parts 17(A-D) for the annular photodetecting elements 11A-11D are formed on part of the respective photodetecting element surfaces and the bonding wires 18A-18D are welded thereto in order to take out electric signals. These wires, supported by junction bodies 19, 19... formed on an insulating protective wire as bridge legs, are led out to the outside circumferential part in the state of insulating the wires from a photodetecting element array 10 and are connected to connecting pins 16E of a case 16. The bonding wires 18(A-D) are formed to an arch shape at the time of providing said wires so that the photodetecting sensitivities of the photodetecting elements 11(A-D) are uniformized even if the optical fibers opposite to the photodetecting element array 10 start rotation motion relative to each other.

Title: Device for treating contaminated water
Inventor: MASADA YOSHIAKI
IPC: B01D21/04
Filed: 1985-11-18
Abstract: PURPOSE:To improve the settling efficiency and the clarifying efficiency of the treated water by arranging a partition plate for separating an influent part and a settling separation part extending from a position below the water surface to the vicinity of the bottom part and a partition plate for separating the settling separation part and an effluent part extending from a position above the water surface to a position in water. CONSTITUTION:The contaminated water wherein flocs have been formed by a flocculant is filled from an inlet 4 into the settling separation part F and the effluent part G through the influent part E of the main settling vessel body to the water surface L. The part e and the part F are separated by the first partition plate 15 and large flocs having a high settling velocity are directly intorduced from the part E into a compression dehydrating bed D. Small flocs having a low settling velocity are sent from the upper end of the first partition plate into a clarification bed B and then settled in a constant-velosity settling bed C and the compression dehydrating bed D. The parts F and G are separated by the second partition plate 16, hence fine flocs suspended in the vicinity of the water surface flow into the part G, access of fine flocs to an overflow through 13 is blocked, and the fine flocs are introduced to the part D from the part C.

Title: Method for removing heavy metal from photographic waste solution
Inventor: STRAUEL PHILIPPE
IPC: C02F1/62
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To efficiently remove heavy metals such as silver and iron by forming hydrotalcite in a waste solution, sufficiently bringing the hydrotalcite and the waste solution into mutual contact, and separating hydrotalcite together with adsorbed heavy metals from the waste solution. SOLUTION: In the case of removal of heavy metals such as iron and silver precipitated from a photographic emulsion, hydrotalcite is at first formed in situ in waste solution. After the waste solution and hydrotalcite are sufficiently brought into mutual contact, the hydrotalcite together with adsorbed heavy metals is so treated as to be separated from the waste solution. The hydrotalcite is produced in situ in the waste solution from precursors directly added to the heavy metals-containing waste solution. These precursors are preferably waste soluble salts and an alkali is added as to precipitate hydrotalcite. Moreover, to carry out these processes, a flocculating agent and/or a silicic acid salt may be used.

Title: Broadcast receiving device
Inventor: KOYAMA TAKAHIRO
IPC: H04B1/16
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a broadcast receiving device which can secure the receiving results containing a smaller number of noises. SOLUTION: A CPU 6 measures the receiving signal intensity right before the reception of signals at the transmitting frequency F1 to FN [Hz] (N: an integer larger than 2) and the frequency F1+A to FN+A [Hz] which are approximate to the frequency F1+FN and radio waves not transmitted. This measurement is carried out based on the AGC signal 12 of a short wave receiver 1. Then the transmitting frequency corresponding to the largest one of ratios of the receiving signal intensity set between the frequency FM (M: all numbers of 1 to N) and the frequency FM+A is set at the receiver 1, and the broadcast is received at this set frequency.

IPC: E02D5/18
Filed: 1990-09-28
Abstract: PURPOSE:To prevent concrete from flowing into an interlocking pipe when concrete is cast into an excavated ditch by providing a pressurizing means to impart pressure to a space in the interlocking pipe. CONSTITUTION:An excavated ditch 1 having desired depth is formed by excavation in such a manner that said ditch is filled with stabilizing liquid 3 to insert two pieces of interlocking pipes 14 along opposite inner walls of said ditch, with opposite ends 14a, 14b of the pipes 14 being opened. A closing lid 14c is placed on the opening at the upper end 14a of one of the pipes 14, so that a space S is provided between the lid 14c and the surface of a liquid 3 which flows into the pipe 14 through the lower end 14b thereof. A vent hole 14d is formed in the lid 14c to connect said hole to a compressor 14f. Next, when concrete 6 is cast into the ditch 1, compressed air is fed into the space S from the compressor 14f to pressurize the space S, preventing thereby the concrete 6 from flowing into the pipe through the opening at the lower end 14b. Consequently, concrete is prevented from flowing into and solidifying in the space in the interlocking pipe 14.

Abstract: PURPOSE:To provide the membership function management device easily managing the membership function. CONSTITUTION:A membership function storage means 3 is constructed by a hierarchical structure where a characteristic of a membership function is contained by its low-order membership function. The means 3 does not store the characteristic common to the high-order membership function from among the characteristic of the low-order membership function, but it stores the membership function correction information correcting the high-order membership function.

Next when pressure oil is intended to be supplied to an oil chamber 12, the pressure oil can not be supplied and the pressure does not rise. Hence, it can surely be detected to be an article of inferior quality.

Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To improve toughness and machinability by incorporating C, Si, Mn, Cr, Mo, W, S, Ca, and the balance essentially Fe in the specific composition. SOLUTION: This steel casting has a composition consisting of, by weight, 0.5-1.2% C, <=3.0% Si, <=3.0% Mn, Sh3.0% Cr, 0.1-8.0% of (2Mo+W), 0.05-0.4% S, 0.0002-0.02% Ca, and the balance essentially Fe. Further, by adding either or both of <=3.0% Ni and 0.05-2.0% V, hardenability can be improved. Further, by adding either or both of 0.02-2.0% Nb and 0.02-2.0% Ta, deterioration in toughness caused by coarsening of crystalline grains when flame hardening is applied to the surface of the steel casting, can be suppressed. Moreover, at the time of manufacture of tools such as dies, it is desirable to apply soaking treatment in the gamma single phase region after forging. By this method, coarse primary carbides formed at the time of casting can be decreased or removed and toughness can be improved.
