Filed: 1993-02-04
Abstract: PURPOSE:To improve economical efficiency and to surely backup an important line by setting priority corresponding to the degree of importance to respective master lines and providing a monitor means and a control means for the master lines. CONSTITUTION:Line switch processing functions (such as a data bus changeover switches 7-1-7-n, CPU 16, memory 17 and time division multiplexing part 8) to be operated when an abnormality monitor part 9a monitors the states of master lines 4-1-4-n and any abnormality is detected, previously sets the priority to the master lines 4-1-4-n corresponding to the degree of importance, the priority of the master line generating the abnormality is checked, and the master line at the highest priority is switched to a slave line 2a and backed up. Thus, even when the plural master lines generate the abnormality, the more important master line is backed up, and the backup system to prevent the severe influences with minimum slave lines can be secured.

Title: Method of burning fuel with moisture instead of air in ignition type internal-combustion engine
Inventor: OOSAKO NOBUYOSHI
IPC: F02B47/02
Filed: 1983-02-04
Abstract: PURPOSE:To increase the output of an engine by adding a fuel such as hydrogen, etc. to oxygen in which water is saturated, instead of suction air. CONSTITUTION:At the time of the suction stroke of an engine, only oxygen to an amount of about 25% of the volume of the engine suction stroke is sucked. Water is mixed into this oxygen in a saturated state and, immediately before this oxygen enters a cylinder, a fuel-air mixture in which an amount of 19-20% of the suction volume of oxygen or gasoline fuel is added, is sent in, and these are compressed, ignited and exploded. At the moment of this ignition and explosion, the combustion of the hydrogen or gasoline fuel in the oxygen provides an extraordinarily high temperature, and the finely atomized water in the oxygen is assimilated in a detonating flame and burned, while producing a strong explosion pressure of about 27 to 30kg/cm<2>. Thereby, fuel consumption can be reduced to less than 30% of the conventional one, preventing environmental pollution due to nitrogen oxide.

Title: Electromagnetic spring clutch
Inventor: OSAWA MASANORI
IPC: F16D27/10
Filed: 1987-01-28
Abstract: PURPOSE:To make accurate angular dividing possible by providing a coil spring which is woundly fixed to a curved turning part abutedly locked or unlocked to the locking part of an armature by turning on or off at its one end, and to the primary rotary shaft at its another end, and extends over the secondary rotating shaft. CONSTITUTION:A clutch comprises a hook 36 formed at the end on the side of the secondary rotary shaft 32, a coil spring 34 woundly fixed to the primary rotary shaft at its another end and extending over both the rotary shafts 30, 32, and the locking part 40 of the hook 36 fitted on its outside armature 24. During the turning off of an electromagnetic coil 18, the hook 36 is locked to a locking part 40 to enlarge the diameter of the coil spring 34 for releasing coupling between both the rotary shafts 30, 32. During the turning on of the coil 18, the hook 36 is released from its locking to the locking part 40 to reduce the diameter of the coil spring 34 for coupling both the rotary shafts 30, 32. Thus accurate angular dividing can be executed by simple structure without accumulated error, resulting in the low manufacturing cost of the clutch.

Title: Method and apparatus for dry-etching
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/3205
Filed: 1994-02-15
Abstract: PURPOSE:To fill a contact hole with an excellent surface flatness by a method wherein a blanket CVD tungsten layer is etched back. CONSTITUTION:A high melting point metal layer 5 is formed over the whole surface of a substrate including a contact hole 6 and radical mode high speed etching and ion mode over-etching are applied. A high density plasma etching apparatus which has a substrate stage shifting means and a substrate bias frequency switching means is employed as an etching apparatus. Therefore, a microloading effect caused by excessive F radicals produced at the time of the overetching can be avoided and etching-back can be realized without abnormal corrosion. Further, as a bulk etching process proceeds with a high etching rate, the decline of a throughput can be avoided. With this constitution, a multilayer interconnection structure with a highly reliable contact plug can be realized.
