Title: Thinning method for welding joint and continuous skin pass mill with thinning device
Inventor: KAMIMURA KOICHI
IPC: B21B1/22
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To completely prevent welding point mark from generating by simultaneously pressurizing/thinning a joint thick thickness part over all region in the sheet width direction. SOLUTION: End parts of a preceding sheet and succeeding sheet of a steel strip 1 are overlapped and welded by a welder 2. The steel strip having a joint thick thickness part 11 formed with lap welding is subjected to skin pass by a skin pass mill 8. In this case, a dedicated rolling mill 3 (thinning device) to simultaneously pressurize/thin the joint thick thickness part 11 over all region in the sheet width direction is arranged at a rear face of the welder 2 and operation is executed. Thus, before the steel strip 1 right after lap welding, the joint thick thickness part 11 is surely and quickly pressurized/thinned, generation of welding point mark at a work roll 9 is completely prevented. By this method, a working time is reduced.

Abstract: PURPOSE:To shorten a charge reception cycle compared to communication channel network charging. CONSTITUTION:A charging signal detection circuit 5 detects a network charging signal transmitted tram the communication channel network so as to collect a utilization charge and receives the utilization charge. A dial number detection part 7 detects a dial number transmitted to the communication channel network and a call originating destination ground decision part 8 decides a call originating destination ground based on the dial number. The storage part 9 of the unit time for the respective grounds stores communication time per a unit charge for the respective call originating destination grounds and the detection and rewrite part 17 of the unit time for the respective grounds rewrites the unit time for the respective grounds with network charging time when the unit time for the respective grounds and the network charging time do not coincide. An extra charging cycle calculation part 11 performs a prescribed arithmetic operation for an extra charge to the communication time and calculates a time interval shorter than the unit time and an extra collection part 12 collects the charge by the calculated extra time.

IPC: F02D45/00
Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To maintain detecting accuracy of an intake air flow by correcting a change of output characteristics of an air flow meter, in a diesel engine with supercharger which is not provided with an intake throttle valve. SOLUTION: A boost pressure Pt is found as an absolute pressure from the boost pressure Pt as a relative pressure detected by the boost pressure sensor and from an atmospheric pressure Pa, and an intake air flow is anticipated from the boost pressure Pt as the absolute pressure and an engine speed Ne. A correction factor is set based on a deviation b between the intake air flow Q detected by an air flow meter and the anticipated value a, and a detected result of the air flow meter is corrected by the correction factor. Setting of the correction factor and correction of the detected result are carried out in a normal operation state and in a non exhaust circulation region and only in a region in which a character of an output change due to a degradation of the air flow meter indicates the same tendency.

At the time of connecting the plates 13 to the main surfaces of the element 12, each plate 13 is put on one main surface of the element 12 by aligning the center of the plate 13 with that of the element 12. After putting, part of the narrow section 19 is welded to the corresponding position of an electrode 14 by bringing a pair of welding terminals into contact with the section 19 and making an electric current to flow between the terminals. Therefore, the fraction non-defective and working efficiency of this positive temperature coefficient thermistor device can be improved and deterioration of the connecting sections between the plates 13 and element 12 can be prevented.

Abstract: PURPOSE:To display characters in an easily visible state by displaying character signals superimposed upon video signals by moving the signals to the upper or lower no-picture section of an image receiver after the signals are separated from the video signals and interpolating the blank section from which the character signals are separated with data obtained by calculation on the basis of the upper and lower or left and right picture element data of the picture. CONSTITUTION:Character signals 32 composed of blank signals superimposed upon a prescribed extent of a picture 21 are discriminated and outputted as character signals 32 when the calculated ratio of the blank signals in the prescribed extent is higher than a prescribed value. At the time of outputting the signals 32, only the signals 32 composed of the blank signals are separated from a prescribed area of standard signals on the basis of the discriminated signal and the signals 32 and standard signals from which the signals 32 are separated are respectively outputted. Then the character signals are synthesized to a no-picture section produced at the top, etc., of the picture by the standard signals from which the character signals are separated after the signals 32 are delayed by desired time and, at the same time, the blank section produced by the separation of the blank signals from the standard signals is interpolated with an interpolating signal. Therefore, both the picture and characters become easily visible.

Abstract: PURPOSE:To prevent the deterioration of an echo path model in two-way simultaneous communication by providing a model state storage section storing tentatively the model the echo path model circuit and providing a switch transferring the model state of between the model state storage section and the echo path model circuit. CONSTITUTION:An input signal from a nearby talker terminal 8 is applied and then two-way simultaneous communication is established, a comparator 9 detects it to inhibit the self correction function in the echo path model 6. Since a state storage section 10 is not affected by the deterioration due to the detection delay caused by the movement from the echo path model 6 to the state storage section 10 in the steady-state and the state of better model than that of the echo path model 6 is kept, the comparator 9 closes a switch 13 and the state of the state storage section 10 is transferred to the echo path model 6. Thus, the deterioration in the echo path model at two-way simultaneous communication is prevented.

Abstract: PURPOSE:To perform an efficient observation by providing an integrated circuit, a shift register and a memory element and observing the output of the memory element by an observing device. CONSTITUTION:Clock pulses outputted from a clock source 8 are inputted to an integrated circuit 1 and a shift register 10, a control pulse generated by dividing the frequency of the clock pulse by (n) is inputted to the integrated circuit 1 and a memory circuit 11. The integrated circuit 1 fixes the conditions of (n) inside positions wherein the signal is observed every time when the circuit 1 receives the control pulse and outputs a signal indicative of the condition as a serial signal of (n) bits according to the clock pulse. The shift register 10 receives the serial signal in synchronism with it. Then, when the next control pulse is received, the memory circuit 11 reads the state of the shift resistor 10 and fixes the state until the subsequent control pulse is received. By observing a parallel signal of (n) bits outputted from the memory circuit 11 by an observing instrument such as a logic analyzer, the state of a logic circuit 2 in the integrated circuit 1 becomes clear.

Title: Water resistant treatment of woody material
Inventor: OZAI KOJI
IPC: B05D5/00
Filed: 1991-10-31
Abstract: PURPOSE:To improve the water resistance of a woody material with an exposed woody fiber layer at the cut end by allowing liq. resin having low viscosity to penetrate into the fiber layer and then blocking the cut end with resin fed. CONSTITUTION:Liq. resin having low viscosity is allowed to penetrate into an exposed fiber layer at the cut end of a woody material and then resin is fed to the cut end. Since the liq. resin is previously allowed to penetrate into the fiber layer, the fiber is made as a coated one with the resin or a resinated state formed by partial integration of the resin and fiber. Accordingly, the later fed resin is not sucked into the gaps in the fiber layer and can effectively be utilized. A tough resin coating film can be formed with the min. amt. of the resin and the cut end can surely be clocked with the resin. Since water can effectively be prevented from penetrating from the blocked cut end, the water resistance of the entire woody material can be improved.
