Title: Treatment of radioactive waste
Inventor: INOUE SHUNJI
IPC: G21F9/06
Filed: 1988-05-12
Abstract: PURPOSE:To incinerate waste active carbon without clogging a ceramics filter as a dust remover and to store the same as stable ashes reduced in volume by crushing the waste active carbon contg. tributyl phosphate prior to incineration and mixing the same with a neutralizing agent. CONSTITUTION:The waste active carbon on which the tributyl phosphate TBP is adsorbed is crushed by a crusher 4 and a stoichiometrically excess amt. of a basic compd. (neutralizing agent) is added from a feeder 5 to a mixer 6; thereafter, the waste active carbon is incinerated in an agitation transfer type circular incineration furnace 9. The waste incineration gas is captured and filtered by the ceramics filter 16. The waste active carbon is crushed to increase the combustion rate prior to the incineration at this time and the neutralizing agent is added to the active carbon prior to the incineration to bring the phosphorus in the TBP into reaction with the neutralizing agent by which the waste active carbon is converted to a high melting material. The clogging of the filter is thereby eliminated. The wider hearth is taken by using the incineration furnace, by which the combustion time is increased. The sufficient and uniform contact with air is maintained and the good temp. conditions are maintained by the agitation arms.

Title: Method and device for measuring thickness of dehydrated cake
Inventor: SHIBAZAKI KAZUO
IPC: G01B11/06
Filed: 1981-07-22
Abstract: PURPOSE:To make the easy and continuous measurement of the thickness of dehydrated cake possible in the measurement stage of the thickness of said cake by intercepting a part of a laser luminous flux by means of the cake layer formed on a drum and measuring the intensity thereof. CONSTITUTION:A filter drum 5 is immersed in sludge mixed liq. 7 stored in a liq. tank 6. Since a filter cloth 9 is wound on the outside surface 8 of the drum and the inside of the drum is evacuated to a vacuum through an air release port, the sludge in the sludge mixed liq. is sucked and captured successively by the filter cloth as the drum 10 rotates, by which it is dehydrated and a dehydrated cake layer 11 is formed on the filter cloth. The cake layer is scraped off by a scraper 12. If a luminous flux of a beam diameter larger than the thickness of the cake layer is irradiated to the cake layer from a laser oscillator 13, part of the luminous flux is intercepted by the thickness of the cake layer. Since the quantity of the intercepted light is continuously proportional to the thickness, the thickness of the cake is obtained by measuring the intensity of the luminous flux with a measuring device 14 for luminous intensity.

Title: Skid control device
Inventor: MATSUMURA AKIRA
IPC: B60T8/66
Filed: 1979-09-07
Abstract: PURPOSE: To obtain a value of a car speed signal which is close to an actual speed in case of a failure in generation of speed signals by obtaining car speed signals at deceleration right before the car speed pulse failure.  
     CONSTITUTION: When a failure in car speed pulse is detected, Q output from a retriggerable monostable multi vibrator (RMMV)15 becomes "0", and a contact piece 33-1 of a switch 33 touches a contacting point (b) side to set a sample hold circuit 32 in a holding condition. Therefore, voltage which corresponds to deceleration right before the car speed pulse failure is impressed upon an unreversed input terminal of an inversion amplifier 31, and electric load is discharged from a condenser 8 at the constant rate that is equivalent to the deceleration rate right before the car speed pulse failure. At this time, as no power is charged from a phase comparator 4, a speed output voltage is reduced in accordance with the deceleration rate right before the pulse failure. Then, again, when a wave shaping circuir 2 starts to normally output the speed pulse, the Q output from RMMV15 becomes "1" and the car speed output voltage becomes the voltage which corresponds to the actual speed of the car at the moment.

Filed: 1992-05-07
Abstract: PURPOSE:To send a reply signal to a terminal station without attenuation by allowing the optical direct amplifier to use a low frequency signal with a high excitation light modulation efficiency for the reply signal and allowing each repeater to reproduce and relay the reply signal. CONSTITUTION:A received light from a transmission line is branched into two at an optical branching device 1 and the one branched light is inputted to a photo diode 14, in which the light is converted into an electric signal and inputted to a BPF 15. The BPF 15 extracts a reply signal f1 sent from each repeater installed to a forward transmission line. The frequency of the signal f1 is selected to be a low frequency offering a high excitation light modulation efficiency. The extracted signal f1 is inputted to a modulation circuit of a monitor control circuit 16 to modulate a drive current. A exciting light source 13 is driven by the drive current to generate a modulation excitation light and it is synthesized with an optical main signal at a optical wavelength synthesizer 2. The synthesized optical signal is amplified and outputted to the other transmission line, then the reply signal f1 is reproduced and relayed. Thus, the reply signal whose main signal S/N is not deteriorated is sent.

Title: Current transformer
Inventor: SUGIO MASATO
IPC: H01F38/28
Filed: 1981-07-23
Abstract: PURPOSE:To equalize flux density distribution in an iron core, by a method wherein a ring-shaped iron core is wound through by compensating winding consisting of first and second winding portions, and said first and second winding portions are wound in different turns with each other, and are differentially connected in series. CONSTITUTION:A ring-shaped iron core 10 is wound by a secondary winding 11 and a compensating winding 12. The secondary winding 11 consists of an integral turn portion 11a and a fractional turn portion 11b. The compensating winding 12 consists of the first winding portion 12a and second winding portion 12b wound along different sides of the ring-shaped iron core 10, respectively, passing through the core 10. The first and second winding portions are wound in different turns with each other and differentially connected in series. Accordingly, the short-circuit current flows through the winding 12 due by the difference of induced voltage between the first and second winding portions. The resultant magnetic flux prevents the flux stream from flowing through the iron core surrounded by the portion 11b, and at the same time, promotes the flux stream to flowing through the iron core radially inner than the portion 11b. Thus, the magnetic flux distributed in the iron core can be equalized practically.

Abstract: PURPOSE: To prevent the occurrence of mis-operation with a simple constitution by performing stopping and releasing between plural operating levers themselves by a lock lever oscillating in cooperation with a recording operating lever and a cam  operating interlocking with this lever.  
     CONSTITUTION: When in a tape recorder or the like a recording or reproducing  state is set by depressing a recording operating lever 13, a lock lever 17 is oscillated  by the pin 107 which is defined by the sloped face 13b of the lever 13, causing the protrusion 17a of the lever 17 to fit into the recess 16a of the cam 16 and a quick lever 14 to be stopped. Hence, the operations such as fast feeding, rewinding, etc by the lever 14 cannot be performed in the recording or reproducing state. When a fast feeding or rewinding state is set by operating the lever 14, the cam 16 is turned by the pin 14a of the lever 14. The lever 7 is then stopped by the cam face 16b and the lever 13 cannot be operated. The same also applies to the cue state, thus the occurrence of miss-operation of the tape recorder or the like is prevented with the simple constitution

Title: Controller of private power generating equipment
Inventor: TANIGUCHI TAKESHI
IPC: H02P9/04
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To regulate the generated power speedily and reduce the power received from a commercial power system, by limiting the target value for generated power of an output signal from an adder-subtractor, amplifying an error between the target value for the generated power and a detected value, and converting it to a rotating speed command signal for a governer. SOLUTION: The target value for received power is constant and generated power does not change suddenly. Therefore, if the received power decreases, a generated power control deviation (Δp) becomes negative. Then, an amplifier 37 continues to amplify Δp until the value of the received power is the same as the target value. After the value of the received power becomes the same as the target value, that value is kept as it is, thereby controlling the received power and keeping it at the target value. A rotation command value for a groverner 4 is given in an analog signal by a rotating speed command converter 39. The rotation command value for the govener 4 is PI-controlled.  By this method, the rotation command value for the govener 4 can be changed rapidly and thereby the power is controlled rapidly and finally the received power can be recovered to the set value immediately.
