Patent JP-H06268589-A (JP)
Title: Optical communications method and communications equipment
Inventor: SAKAI HIDETOSHI
IPC: H04B10/07
Filed: 1993-03-15
Abstract: PURPOSE:To attain the communication unless a fault takes place simultaneously in an active system and a standby system. CONSTITUTION:When a fault takes place between a 1st stage repeater 2a and a 2nd stage repeater 2b in existence in a transmission line of an active system, for example, the 2nd repeater 2b sends the effect that a controller 4 detects a fault. In this case, the repeater 2b allows the controller 4 to switch an optical switch 9 to the position of a contact (b) thereby pulling in standby system transmission data via an optical branch coupler 8 of a correspondent repeater 2b'. Thus, the repeater 2b of the active system takes in normal data corresponding to fault information from the repeater 2b' of the standby system and sends the data to a repeater 2c of the next stage.

Title: Recovery of terephthalic acid
Inventor: ARASHI MASAKIMI
IPC: C07C63/26
Filed: 1983-03-31
Abstract: PURPOSE:Terephthalic acid in an aqueous solution of its alkali metal salt is allowed to precipitate acidically by using a weak acid whose acid dissociation constant is in a specific range whereby the size of the precipitate is made large to facilitate separation, draining and drying and high-purity terephthalic acid enough to be used readily without purification is recovered. CONSTITUTION:An aqueous solution of an alkali metal terephthalate, such as a waste solution after the thinning finish of polyester filaments with aqueous alkali metal hydroxide, is treated with an acid whose acid dissociation constant is in the range from 1.5-5.0 in pKa, for example, acetic acid (4.76), formic acid (3.75) or phosphoric acid (2.15 at the first dissociation) and the precipitate formed thereby is recovered. The use of the wead acid grows the crystals of the formed terephthalic acid more than 25 microns in size to enable sedimentation separation. In the draining process, the content of water readily reaches lower than 50%, thus the energy for drying is saved. Further, rinsing becomes so easy that contamination with the salt can be avoided.

Title: Generator for pcm signal
Inventor: YAMADA YASUHIRO
IPC: H03M3/04
Filed: 1978-05-08
Abstract: PURPOSE: To make it possible to use an A-D converter for a small number of bits and also to generate a normal PCM signal by A/D-converting the differential signal of an analog signal and by accumulating it.  
     CONSTITUTION: Analog signal S 1  is sampled by S/H circuits 2a and 2b respectively and differential analog signal S 4  is A/D-converted 3 by a digital PCM system as the word goes. Since the above-mentioned signal S 4  has its dynamic range narrower than that of signal S 1 , a converter for a small number of bits can be used. Next, SUM7 accumulates sequentially signals of converter 3 and outputs a numeral signal equivalent to the accumulation value at constant intervals of time. In this way, normal PCM signals can be obtained at terminal 4. Even if an inexpensive A/D converter is used, therefore, an analog signal with the broad dynamic range can be converted into a PCM signal.

Title: Reverse preventer for internal combustion engine
Inventor: HIRANO YUICHI
IPC: F02D17/04
Filed: 1989-03-07
Abstract: PURPOSE:To perform a reverse judgement with one sensor by performing this reverse judgement through size relation with a passing time at engine ungenerating reverse rotation from a time when a detected body passes through a passage detecting means. CONSTITUTION:A time when projections 1, 3, 4 at 10 deg. in projection width angle and a projection 2 at 50 deg. set up at regular intervals by rotation of a rotor 21 by a single cylinder engine 10 pass through a magnetic pickup sensor 22 is counted by a central processing unit 32 of an electronic controller 30. Whether it is reverse rotation or not is judged from size relation between a time ranging from a terminal of the projection 2 at engine speed ungenerating reverse rotation and a passage time ranging from the terminal of the projection 2 to the next projection 1 when the reverse rotation occurs. When the reverse rotation is judged hereat, a control signal SG4 is outputted, at least either of ignition and fuel apply of the engine 10 is cut off. Thus, even in an internal combustion engine securing a reference signal and an angle signal by one sensor, reverse judgement can be performed.

Title: Automatic receiver for radio wave transmitted from mobile station
IPC: H04W16/28
Filed: 1992-03-13
Abstract: PURPOSE:To use the receiver with high reliability over a long period by receiving a television signal from a program source transmitter with plural stationary antennas installed while being directed in multidirection. CONSTITUTION:Each of antennas 1-8 of an antenna section 9 installed in multi-direction is connected to a switch 12 and an FPU (program source transmitter) reception control section 11 sweeps the antenna for a prescribed time interval. When the radio wave sent from the FPU is received by, e.g. a stationary antenna 1, the received signal is amplified by a low noise amplifier 13 through a switch 12 and an FPU receiver 14 divides the amplified signal into an intermediate frequency and a demodulation signal. The intermediate frequency signal is used to discriminate the presence of the signal and the demodulation signal is used for confirmation and discrimination of the television signal. When the FPU automatic reception control section 11 discriminates the signal to be the television signal, the control section 11 decides the direction of the arrival of the radio wave and allows an FPU reception section 10 to set the FPU reception state. Then the reception level is always confirmed and when any change is in existence, the phase control section controls a phase device 1a to ensure a maximum level.

Title: Pattern forming material
Inventor: TODA KAZUO
IPC: G03F7/023
Filed: 1982-03-31
Abstract: PURPOSE:To reduce swelling during development and to enhance resolution and positioning accuracy by using a polymer having >=2 naphthoquinonediazido groups in the molecule and a polymer having acid chloride in the side chain as pattern forming materials. CONSTITUTION:It is well known that naphthoquinone diazide forms carboxylic acid when irradiated with ultraviolet light. A compound having >=2 naphthoquinonediazido groups in the molecule is utilized as a cross-linking agent after irradiation with ultraviolet rays, and by incorporating carboxylic acid chloride which reacts very efficiency with carboxylic acid into a polymer, a cross-linking reaction is rapidly caused by heating. When said compound and polymer are used as pattern forming materials, swelling is hardly caused, and the resolution of the resulting pattern and the positioning accuracy are enhanced.

Abstract: PURPOSE:To provide excellent non-adhesion, and high rubber elasticity and heat resistance in a roll having a rigid core and an non-adhesive coat by forming the non-adhesive coat layer with a peroxide cross-linked fluorine rubber in which a low molecular weight polytetrafluoroethylene is mixed. CONSTITUTION:An non-adhesive coat layer is formed out of a peroxide cross- linked fluorine rubber in which a low molecular weight polytetrafluoroethylene is mixed. The peroxide cross-linked fluorine rubber is a fluorine rubber of the type in which a halogen, particularly, bromine and/or iodine, and hydrogen atom are introduced into the polymer molecule chain terminal and side chain, and the cross-linking is conducted by the abstraction reaction of halogen atom and hydrogen atom. As the peroxide cross-linked fluorine rubber, a high molecular weight one having a Mooney viscosity ML1+10 (100 deg.C) of 90 or more is preferably used. The mixing ratio of the low molecular weight polytetrafluoroethylene is not particularly limited, but 60 parts by weight or more is desirably mixed per 100 parts by weight of the fluorine rubber to provide sufficient non-adhesion.
