IPC: H04Q9/00
Filed: 1984-01-30
Abstract: PURPOSE:To utilizie overlappingly a slave device to plural signal paths in addition to the simplicity of a signal transmission means by coding a supervisory signal and a control signal of slave devices in a remote supervisory and controlling system having multi-stage hierarchy connection. CONSTITUTION:The lowest order slave device 7 detects a change in an input signal line, and the state change information, a supervisory signal comprising an input line code 9 and state change information 8 as shown in Fig. A is transmitted. The salve device 5 adds an input line code signal 10 to the inputted supervisory signal as shown in Fig. B and transmits the result further to the high- order slave device 3. The supervisory signal inputted to a master device 1 via high-order slave devices of a prescribed number according to the signal transmission means consists of the state change information 8 of the slave device 7 and plural input line code signals 9-11 as shown in Fig. C and the master device 1 discriminates the information from which input line of slave station the information comes. Similarly, the control signal transmitted from the supervisory controller to the low-order direction of the slave supervisory controller is transmitted while the code signal of each supervisory controller is added in the opposite order.

Title: Exhaust gas purifier for internal combustion engine
Inventor: SHINDOU HIROSHI
IPC: F01N3/20
Filed: 1980-02-08
Abstract: PURPOSE: To restrict abnormal overheat of exhaust gas purifying catalysts by forking an exhaust pipe connected to one cylinder into a few branch pipes and disposing the exhaust gas purifying catalysts on the way of the branch pipes, respectively.  
     CONSTITUTION: An exhaust pipe 20 is connected to a cylinder 10 of an internal combustion engine and exhaust purifying catalysts 30a, 30b are disposed on the way of branch 20a, 20b, respectively. As a great amount of unburnt gas generated due to a misfire inside the cylinder 10 is separately fed to each catalyst, its abnormal overheat caused by a reaction heat generated in each catalyst may be restricted. In addition, as a small-sized catalyst converter is used, an exhaust gas is prevented from running through a specific area inside each purifying catalyst, thereby facilitating catalyses.

Abstract: PROBLEM TO BE SOLVED: To prevent the unauthorized use of a program by a third party by ciphering deciphering key data outputted from an IC card by common key data and outputting them. SOLUTION: The cipher generation part 16 of the IC card generates the cipher generation information data (YB) of a prescribed length by a power remainder arithmetic operation in a power remainder arithmetic operation part, based on a random number (XB) generated in a random number generation part. The cipher generation information data (YB) are outputted through an IC card reader to a game machine body. Also, the cipher generation information data (YA) generated by a cipher processor 11 are outputted from a game machine as well and inputted to the power remainder arithmetic part of the IC card and the common key data (KAB) are generated by performing the power remainder arithmetic operation of the respective cipher generation information data (YA) and (XB) by the power remainder arithmetic part.  Based on the common key data (KAB), the deciphering key data stored in a ROM part are ciphered in a ciphering arithmetic operation part.

Title: Digital-to-analog converter
Inventor: SHIMOMURA HIROSHI
IPC: H03M1/68
Filed: 1981-02-04
Abstract: PURPOSE:To obtain a D/A converter having high accuracy and a low cost, by adding an accessory circuit to an ordinary D/A converter which is put on the market. CONSTITUTION:An EPROM2 received an m-bit digital signal 1 discriminates an optional value which is set to perform a fine/rough switching action and produces a switch signal 4. At the same time, the EPROM2 transmits a 2-bit digital signal to a selector 5. Receiving the signal 4, the selector 5 transmits an n-bit signal 7 to a D/A converter 6. In this case, the low-order q-bits of the fine side (low-order bit side) are cut, and the number of superposed bits of the rough side (high-order bit side) is set at p-bits. As a result, the LSB of the fine side has the 1/2<n-1-q> weight for the output signal of the converter 6. Here the ratio of a fine resistance group 9 is decided by Ac/Af=2<n-p>, where the amplification gains of the rough and fine sides are Ac and Af, respectively. At the same time, the limit of resolution M is defined by n+1<=M<=2n-1 for a D/A converter.

Filed: 1980-02-09
Abstract: PURPOSE: To treat the titled exhaust gas without requiring desulfurizing equipment by adjusting the amount of limestone powder blended in starting materials for sintering and allowing unslagged lime in a region of a sintering zone to capture and fix SO x .  
     CONSTITUTION: Blended starting material 1 for sintering consisting of fine iron ore, 8W20wt% limestone powder, coke breeze and a little water is charged into the pallet and fired with firing furnace 3. Sintering progresses while leaving wet unsintered zone 6 at the lower part in the early stage of firing, burning zone 7 and sintering zone 8 and slowly extended, and sintering is completed at the right end of the pallet. Unslagged lime (free lime) remains in sintered ore 8 in the form of quick lime even after passing through zone 7. Accordingly, exhaust gas of high SO x  concn. from latter half part VIWIX of wind boxes 4 is fed through hood 10 to allow unslagged lime in 800W1,000°C region 9 of zone 8 to capture and fix SO x . Thus, the SO x  content of exhaust gas exhausted from first half part IWV of boxes 4 into chimney 5 is reduced to ≤20%, resulting in ≥80% desulfurizing rate due to sintered ore 8.
