Title: Fuel controller for engine
Inventor: TERAO SHUJI
IPC: F02D41/04
Filed: 1989-06-29
Abstract: PURPOSE:To soften the deceleration shock and improve fuel consumption by executing fuel cut after the shorter delay time in comparison with the operation in the state where the air-fuel ratio is rich, when the deceleration state in which fuel cut is executed in the state where the air-fuel ratio of the mixed gas is lean is generated. CONSTITUTION:A control unit 1 consisting of a microcomputer, etc., executes a prescribed calculation processing on the basis of each detection signal of a variety of means for detecting the engine operation state such as air flow meter 2, throttle sensor 3, idle switch 4, revolution sensor 5, and a linear O2 sensor 6, and controls the fuel supplied from an injector 7. In this case, if a declaration state where the engine satisfies the prescribed fuel cut condition is generated, the control unit 1 determines the delay time for the fuel supply according to the air-fuel ratio of the mixed gas at this time point. As the air- fuel ratio of the mixed gas becomes lean, the above-described delay time is shortened.

Title: Refining of product containing estersof non-prduced sugar and more than one type of fatty acid
Inventor: KIISU KOOTSU
IPC: B01D11/00
Filed: 1990-06-22
Abstract: The invention relates to a process for purifying crude products containing esters of a non-reducing sugar like sucrose, and one or more fatty acids such as palmitic acid, stearic acid etc. by subjecting said crude esterification products to an extraction treatment with supercritical carbon dioxide. After carrying out this extraction treatment a residue comprising the fatty acid esters of non-reducing sugars, the unreacted sugar and the salts as well as an extract comprising the fatty acids, fatty acid alkyl esters and also any solvents, if present, are obtained. The unreacted sugar and salts, present in the obtained residue, can be removed from said residue by, for example, a washing operation resulting in a final product of pure esters of the non-reducing sugar and one or more fatty acids. This last removal step concerning the unreacted sugar and salts may also be carried out before the application of the above indicated extraction treatment with supercritical carbon dioxide.

Title: Superconductive apparatus
Inventor: AMANO TOSHIYUKI
IPC: H01F6/04
Filed: 1984-08-06
Abstract: PURPOSE:To contrive to reduce the reserved amount of liquid helium by a method wherein a flexible continuous porous substance capable of keeping liquid heliumis provided by including at least part of the cooled surface of a superconductive magnet in contact. CONSTITUTION:The flexible continuous porous substance 6 capable of keeping liquid helium by sucking it up by capillary phenomenon is provided by including at least the cooled surface of the superconductive magnet (SCM)1 in contact. This manner enables LHe to be kept in gaps of the porous substance 6 by capillary phenomenon even if the upper part of the SCM1 is evaporated above the LHe surface; therefore, the exposed part of the SCM1 comes into contact with the LHe in most part of its surface. When the SCM1 is excited under such a situation, the good characteristic of thermal conduction is kept even under some thermal disturbance, and this apparatus can be operated without the trouble of quench because of being maintained at LHe temperature. As a result, the reduction in LHe consumption and the LHe content in the cryogetic container 2 can be contrived, and the whole apparatus can be contrived to be made compact.

Filed: 1990-06-27
Abstract: PURPOSE:To improve the throughput of a CPU by performing DMA transfer in a local bus by controlling a local bus controller separately when a DMA requirement is issued from a DMA controller to the bus controller. CONSTITUTION:A system bus used by the CPU 10 is separated from the local bus used by the local bus controller LBC 1, the DMA controller 11, a peripheral LSI 12, and a RAM 13. When the requirement of DMA transfer is issued from the controller 11 to the LBC 1 while the CPU 10 makes access a device at a local bus side, the LBC 1 outputs no hold acknowledge signal 1b positively to the controller 11 until access at the local bus side of the CPU 10 is completed, and performs no DMA operation by making the DMAC 11 await. In such a manner, the throughput in a system with high frequency of DMA transfer can be improved.
