Inventor: SAKAMOTO MASAKI
IPC: C21D9/00
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a chain having excellent rupture toughness at a low temp. in a flash butt weld zone by subjecting a steel bar consisting of a low alloy steel to two times of hardening and tempering treatments in a heat treatment after chain making and further limiting the heating temp. in the respective heat treatments to a specific range. CONSTITUTION:The steel bar consisting of the low alloy steel is cut to a prescribed length and is formed to a toric shape; thereafter, the end face is subjected to flash butt welding and studs are press-fitted thereto to form the chain. The chain is further subjected to the heat treatment, by which the large- diameter chain is produced. The chain is subjected to the tempering treatment at 500-700 deg.C after two times of hardening including primary hardening by which the chain is cooled after heating to 900-1,050 deg.C and secondary hardening by which the chain is quickly cooled after heating to 850-950 deg.C as the heat treatment after the chain making. The high rupture toughness chain useful under sever conditions such as anchoring of an ocean structure, for example, rig for petroleum drilling is obtd.

Abstract: PURPOSE: To greatly enhance the sensitivity of a photoelectric surface by allowing antimony to sublimate or evaporate at a temp. below its melting point, evaporating thereafter an alkali metal, activating it for reactions in a vacuum, and thereby forming a photoelectric surface. CONSTITUTION: In formation of a photoelectric surface, a vacuum envelope 13 fitted interiorly with an input screen 14 is held at a high degree of vacuum, and current is fed in such an arrangement that an antimony (Sb) vapor source 18 is installed in the envelope 13 while confronting the screen 14. Therein the feed current is predetermined so that the vapor source 18 becomes below 630 deg.C which is the melting temp. Then observation is made by a photo-ray penetrating amount sensor 19 by current feed and incandescence of the vapor source 18.

Then current is fed to an alkali generator 20 and alkali vapors of K and Cs are introduced to the envelope 13, and alkali metal is evaporated and activated for reactions in a vacuum so that a photoelectric surface is formed.  According to this constitution, alkali metal molecules intrude into antimony film so that a sufficient activation is achieved, and it is practicable to enhance the sensitivity to a great extent.

Title: Sub-synchronous detection type radio equipment
Inventor: ANDOU ATSUHISA
IPC: H04B1/707
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To properly reproduce data in simple configuration even when there is carrier offset. SOLUTION: Code converters 16 and 17 perform code conversion from NRZ signals to differential signals by discriminating the polarities of NRZ signals contained in in-phase and quadrature-phase base band signals outputted from mixers 12 and 13 (actually on the basis of the result of comparing upper and lower limit levels in the dead zone of a circuit). On the basis of the differential signal, differential decoders 18 and 19 decode respective codes constituting a spreading code. Correlators 20 and 21 inversely spread the in-phase and orthogonal-phase base band signals having the decoded codes while using the spreading code. A switcher 22 selects the base band signal of a greater correlation value and supplies it to a demodulator, etc. A frequency regulator 24 regulates the frequency of a local oscillation signal so that the swell cycle of the in-phase or orthogonal-phase base band signal can be longer than a prescribed cycle, namely, the number of NRZ signals can be reduced.

Title: Washer also working dehydrator
Inventor: YAMASHITA KIYOSHI
IPC: D06F33/47
Filed: 1978-04-14
Abstract: PURPOSE: To prevent an overflow accident at an abnormal time, by setting the device so that a flow volume from an electromagnetic valve at a drainage passage will be larger than a flow volume to the valve, and by detecting whether water is normally drained or not due to the presence of decrease in the pressure at a flow-in side.  
     CONSTITUTION: When a washing process is changed to a dehydrating process by means of a timer, an electromagnetic valve 39 is opened and water in a water passage 41 is drained through the valve 39. Since the device is set so that a flow to the valve 39 will be smaller than a flow volume from the valve, the pressure in an air trap 37 becomes low, a water level switch 42 detects it and starts to drive a bath 4. Then water in the bath 4 is discharged into a upper casing 2 through a space 6 due to a centrifugal force, and is drained through a drainage hose 27. Since water is not drained through the valve 39 at an abnormal situation such as occurs due to forgetting to bring down the drainage hose and so on, the pressure in the trap 37 does not lower, and the rotation of the bath, which is driven by means of the switch 42, does not start. An overflow can thus be prevented.

The filtering agent 2 is piled up to thickness of 1m on a filtering bed 3 in a filtering tank 1, to constitute a filtering layer. On the occasion of filtration, pressurized air is charged in a pipe 4 for the inflow of raw water to hold the sufficient amount of dissolved oxygen in the phosphorus-dissolved raw water. Thereafter, a ferrous sulfate solution is injected into the raw water from a connecting pipe 5 connected to the pipe 4 for the inflow of raw water. After the raw water is filtered in the filtering tank 1 under the condition of LV= 12.5m/H and SV=12.5l/H, it is withdrawn through a pipe 7 for with-drawing purified water.

IPC: G10L25/00
Filed: 1988-02-25
Abstract: PURPOSE:To obtain an artificial voice producer with a large sound volume by providing a reed body in almost parallel with the axial line of an air path. CONSTITUTION:A reed body 41 is provided in almost parallel with the axial line of an air path 19. Namely, the reed body 41 oscillates and produces voices due to the air flow passing through the air path 19 and when the reed body 41 produces voices, the contacting position of the reed body 41 with its facing section 47 changes depending upon the flow rate of the air flow. Therefore, voices of desired tones can be produced. Since the reed body 41 is provided in almost parallel with the axial line of the air path 19, the length of the reed body 41 can be set optionally. In other words, the opening area of the facing section 47 can be enlarged irrespectively of the cross-sectional area of the air path 19. Therefore, an artificial voice producer of a large sound quantity can be obtained.
