Title: Treatment of building waste and utilization thereof
Inventor: OTA TATSUMI
IPC: C04B18/26
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To carry out the detoxifying treatment and effective utilization of a waste by chipping a woody material, stirring and mixing the resultant chips with a cement as a binder and solidifying the prepared mixture into the form of blocks. SOLUTION: A woody waste such as a formwork waste or a demolished material of a woodwork in a building field is collected and crushed into chips having about 10-50 mm size. The resultant chips are used and compounded with a cement paste (25-50% W/C) at 1/(0.015-0.07) volume ratio of chips/cement and, as necessary, an adequate amount of a fine powder produced from a reclaimed aggregate of a concrete is compounded therewith. The resultant mixture is then stirred and mixed. The prepared mixture is subsequently filled in a formwork, compacted with a vibrator, etc., and solidified to form blocks of an optional shape such as a rectangular parallelepiped, a cylinder or a plate and an optional size. The blocks are rich in water permeability due to a high void ratio thereof and handling is readily carried out due to light weight thereof.  Thereby, the blocks can be used for a paving board, a laying material for a walk, a fence for a boundary, a substrate material, etc.

IPC: H04L25/02
Filed: 1992-06-15
Abstract: PURPOSE:To eliminate the need for improvement of connection by detecting connection error even when the polarity is not correct so as to send transmission data of correct polarity. CONSTITUTION:When the connection of branch lines 3a, 3b to positive/negative signal lines 2a, 2b is correct and a start bit detection circuit 5 detects a start bit from binary reception data from a reception circuit 4, a level of a start bit in inverted transmission data inputted from the signal line 2b from a polarity level detection circuit 6 via the branch line 3b is negative. When the connection is wrong, the level of the start bit is positive, a discrimination circuit 7 discriminates the state and outputs the result to a transmission changeover circuit 8. When the connection is correct, the circuit 8 outputs the transmission data of the transmitter 1 to the branch line 3a and the signal line 2a via a transmission circuit 9 and sends inverted transmission data to the lines 3b, 2b via the transmission circuit 9. When the connection is wrong, the circuit 8 sends the transmission data to the line 2a and the inverted data to the line 2b. Thus, the positive polarity data are sent to the lines 2a, 2b even when the connection is wrong.

Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a spectrometer in which a true peak is determined from a spectral data through a simple arrangement with no effects from ghost peaks. SOLUTION: A hybrid power spectrum H(x) is calculated (150) from the square root of the product of the background power spectrum B(x) and the sample power spectrum S(x) being measured, based on the spectral data of an adsorbed species analyzer. A noise-enhanced spectrum Rn(x) is then calculated (160), depending on the B(x), S(x) and H(x) according to a formula; Rn(x)= H(x)-S(x)+1}  S(x)/B(x)}. Furthermore, a peak-enhanced spectrum Rp(x) is then calculated (170) depending on the B(x), S(x) and H(x) according to a formula; Rp(x)= H(x)-B(x)+1} S(x)/B(x)}. Subsequently, the standard deviation δ is calculated, based on the Rn(x) and the intensity of spectral data at such (x) that the first-order derivative of the Rp(x) is larger than the standard deviation δ is determined (190) to be a peak.

Title: Optical transmission system
Inventor: FUJIOKA FUMIO
IPC: H04B10/00
Filed: 1986-07-04
Abstract: PURPOSE:To obtain an optical transmission system whose picture quality is not deteriorated even if a normal photocoupler is used while using one optical fiber by transmitting a control signal during a synchronizing signal detection period for a video signal. CONSTITUTION:The video signal obtained by an ITV camera comes to an optical receiver 6 through an optical transmitter 5, a photocoupler 9A, an optical fiber 10 and a photocoupler 9B. A synchronizing signal detection circuit 12 makes the output signal B of the video signal A at a level H during the period of the horizontal synchronizing signal included in the video signal A, and passes a control signal C coming from a terminal 3 through an AND gate 19. A control signal D comes in the optical receiver 8 through the optical fiber 10 from the optical transmitter 7. A triggerable multivibrator 18 reproduces the control signal C, which is transmitted to the ITC camera from an output terminal 4. The output of the optical transmitter 7 leaks to the optical receiver 6 through the photocoupler 9B. However, during said period only the horizontal synchronizing signal is transmitted, which never affects picture quality.

Title: Attenuator
Inventor: MIYAMOTO MASANORI
IPC: H03H7/24
Filed: 1978-12-18
Abstract: PURPOSE:To enable to make almost completely zero that the output signal at maximum attenuation, by the constitution of two resistor networks, switching elements of the same number as resistors, and control circuit performing ON, OFF controlling the switching elements. CONSTITUTION:Assuming that the switching elements S1-S4 are all closed when the output 4-bit of the control circuit 6 is 0000, the output of the resistor network 7 in this case is grounded via the elements S1-S4. Thus, when the ON resistance of the elements S1-S4 is neglected, the attenuation is infinitive and the output signal is completely zero. When the number of counts is sequentially increased from this state, the switching of the elements is controlled and the attenuation is sequentially made small. Further, when the output of the circuit 6 is 1111, all the elements S1-S4 are opned and the attenuation is minimized. By selecting the resistance value for each resistor, the change in the output signal level to the number of counts can be almost made to straight line.

Title: Water purifier
Inventor: ARAGADA KUNIKAZU
IPC: C02F3/06
Filed: 1981-10-01
Abstract: PURPOSE:To simplify the structure of a water purifier and to enhance its purifying power, by communicating two purifying cells having the differences of head and packed with porous fillers each having specific gravity of about 1 through a siphon, and providing washing pipes for washing sludge at the bottoms of both of the cells. CONSTITUTION:Waste water flowing into the first purifying cell 2 is brought into contact with a filler 4. When it reaches HWL, the waste water in the cell 2 is let flow through a siphon 6 into the second purifying cell 7. When the cell 2 becomes empty and the waste water is reserved in the cell 7 only, the water level in the cell 2 is gradually raised by inflow from an inflow pipe 1 and a circulating pipe 13. When the water level in the cell 2 comes near HWL, the cell 7 becomes almost empty. The fillers 4, 10 charged in the cells 2, 7 have apparent specific gravity of about 1, so that each particle can be separated from other and easily washed by pouring a slight amount of washing water through washing pipes 17, 18. The entire parts of the cells 2, 7 except their bottoms are repeatedly alternatively submerged and exposed, and the fillers 4, 10 being porous have proper water- and air-permeability so that they can aerobically decompose organic substance.

Title: Snubber circuit of gate turn-off thyristor
Inventor: FUKUI HIROSHI
IPC: H02M1/06
Filed: 1980-11-10
Abstract: PURPOSE:To suppress the overvoltage at the early time of turn-ff, by using a diode to which the platinum is doped for an overvoltage absorbing circuit of a gate turn-off thyristor. CONSTITUTION:A capacitor 2 is connected in series to a parallel circuit of a diode 4 and a resistance 3 to form an overvoltage absorbing circuit. This absorbing circuit is connected in parallel to a gate turn-off thyristor GTO1. When the GTO1 is turned on, the discharged current of the capacitor 2 passes through the resistance 3 to reduce the discharged current value during the turn-on. While the load current passes through the diode 4 to charge the capacitor 2 when the GTO1 is turned off. Thus the voltage increase factor is suppressed for the GTO1. A diode to which the platinum is doped has a low degree of the forward recovery and has a low level of the generated voltage when it is turned on. Accordingly the overvoltage of the GTO1 is suppressed at the early time of turn- off.
