Abstract: PROBLEM TO BE SOLVED: To enhance water stopping property by forming a projection plate part on the end of one hand being a front side and rear end side in the axial line direction of a tunnel, and forming an engaging part engaging with the projection plate part on the other end. SOLUTION: An inner form 3 is assembled rearward of a skin plate 2 while ground G is excavated by a shield excavator 1 to form a shaft, and a water stopping form 11 is arranged on the outer peripheral side of the inner form 3. The new inner form 3 is joined rearward of the preceding inner form 3 while the ground G is excavated. An engaging stage part 13 of the rearward side end 11b of the new form 11 is engaged to be joined on a water stopping plate part 12 of a frontward side end 11a of the preceding form 11. Next, a space between the form 11, a peripheral wall TW of the shaft and a gable side form 8 is filled with a self-hardening filler 4 to form a covered wall W. Furthermore, the excavator 1 is advanced frontward, and the new inner form 3 and the form 11 are assembled. Furthermore, similar working is repeated to construct a tunnel T. Thereby water stopping property is enhanced.

Abstract: PURPOSE:To improve the degree of integration, and to shorten the time for automatic wiring by determining the area of each block and the position of an external terminal and disposing standard cells in succession in response to the input-output of a signal from the external terminal in respective blocks. CONSTITUTION:The areas of each block 40-44 are calculated by standard cells such as ones 46-50 in a block such as one 40 and wirings first, and the positions of external terminals 40a-40g, 41a, 42a-42c, 43a, 44a, 44b for separate block are determined so that wiring distances among the blocks are minimized. The standard cells are arranged in succession along the flow of signals from the positions of each block external terminal. The standard cells are disposed along the flow of the signals in respective blocks, wiring channel regions are reduced because the external terminals for respective blocks are decided so that the wiring distances among the blocks are minimized, and the standard cells need not be rearranged because the areas are calculated in consideration of wiring channels in respective blocks. Accordingly, the time for automatic wiring can be shortened.

Title: Exhaust purifying facility for engine
Inventor: OOKUBO KENJI
IPC: F01N3/02
Filed: 1984-04-03
Abstract: PURPOSE:To remove combustible particles contained in the exhaust gas of an engine effectively, by providing an injector for injecting a catalytic solution and hydrochloric acid substantially simultaneously on the upstream side of a particulate filter, and burning combustible particles effectively even when the temperature of exhaust gas is low. CONSTITUTION:When the back pressure of an engine 1 becomes higher than a predetermined value due to clogging of a particulate filter 4, a pump 9 of an injecting means 5 is set into operation and a mixture liquid is injected from an injector 7 into an exhaust pasage 3 on the upstream side of the filter 4. Resultantly, a catalytic component and hydrochloric acid pre-dissolved in the mixture liquid cover uniformly the surfaces of combustible particles captured by the filter 4. Thus, catalytic reaction is caused between the catalytic component and the combustible particles, and hydrochloric acid activates the surfaces of the combustible particles by forming an easily burnt composite matter.

Title: Cleaning method for carbon monoxide sensor and carbon monoxide detector
Inventor: KONO TAKASHI
IPC: G01N27/409
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent a change with the passage of time of a sensor by a method wherein, while the temperature of the sensor is being kept higher than that in a measurement, a voltage is applied across sensor electrodes for a definite time. SOLUTION: The temperature of a sensor is raised to about 600 deg.C or higher, 5 V is applied for about ten seconds, a polarization treatment is executed, the temperature of the sensor is kept at about 600 deg.C for about five seconds, and an operating temperature is set at about 400 deg.C. After the polarization treatment, the temperature of the sensor is kept at about 600 deg.C for about five sencods so that an air-based return is made quickly. Normally, the treatment for about one to 20 seconds is sufficient. By the polarization treatment, the output of the sensor with reference to carbon monoxide is increased, the sensitivity of the sensor with reference to hydrogen is decreased, and the S/N ratio of the sensor is enhanced relatively. By this method, a change with the passage of time of a solid electrolyte-type carbon monoxide sensor can be reduced, and an air-based change can be reduced, the carbon monoxide can be measured precisely, and the life of the sensor can be made long.

IPC: H03H11/04
Filed: 1990-03-16
Abstract: PURPOSE:To reduce the chip size in the case of circuit integration by connecting a capacitor between output terminals of a voltage current converter. CONSTITUTION:A capacitor is provided between output terminals of voltage current converters 1, 3 and between output terminals of voltage current converters 2, 4 and a resistor 13 adjusting a current of a current source determining a mutual conductance of the voltage current converters 1, 3 and a resistor 14 adjusting a current of a current source determining a mutual conductance of the voltage current converters 2,4 are provided to the active filter. In this case, as the basic operation, a constant of the filter is decided by the mutual conductance of the voltage current converters 1-4 and capacitors 5,6. Since the capacitors 5,6 are connected between a circuit point when a noninverting signal just appears and when an inverting signal just appears because of the input signal is balanced, the circuit is equivalent to that one capacitor connects between an output terminal of the voltage current converter 1 and ground and the other capacitor connects between the ground and an output terminal of the voltage current converter 3. Thus, in the case of circuit integration, the chip size is decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a transmission and reception circuit, capable of performing the transmission and reception of signals utilizing the advantage of differential signals. SOLUTION: Two or more pairs of signal transmission lines S1-S4 are provided on a plane provided with noise generation source A and B for the noise generation sources A and B adjacent to both sides of a signal line S.

Title: Control device for continuously variable transmission
Inventor: MORIMOTO YOSHIHIKO
IPC: B60W10/101
Filed: 1986-03-25
Abstract: PURPOSE:To ensure a smooth change gear control at the time of transition so as to improve convergence performance by determining a gear shifting speed based on a target variation of an element for advance in phase corresponding to delay in a drive system including a target change ratio and an actual change gear ratio whereby establishing manipulated variables based on said gear shifting speed and the actual change gear ratio. CONSTITUTION:An actual change gear ratio, a target change gear ratio, and change in speed of the target change gear ratio are obtained by an actual change gear ratio computing section 45 of a control unit 40, a target change gear ratio retrieval section 46, and a target gear shifting computing section respectively. Then a gear shifting speed computing section 49 computes the gear shifting speed based on the above mentioned values taking an element for advance in phase into consideration. In this case, when a deviation of the target change gear ratio is small, the gear shifting speed becomes low, and the gear shifting speed becomes higher as the deviation becomes greater. As a result, the smooth characteristics of gear shifting can be obtained continuously at the time of transition whereby convergence performance of the actual change gear ratio toward the target change gear ratio is improved.
