Title: Control device of internal combustion engine
Inventor: TAKAHASHI HIDEAKI
IPC: F02D43/00
Filed: 1995-05-19
Abstract: PURPOSE: To suppress the deterioration of the operating property owing to the over shoot to the lean side, by correcting to advance the ingnition timing when the control speed to pontrol the air-fuel ratio to the lean side is higher than a prescribed value, as well as converting the control speed in an air-fuel ratio feedback control means according to the operating condition. CONSTITUTION: A control unit 23 which inputs the detecting signals of a throttle sensor 10, a crank angle sensor 11, a water temperature sensor 12, an oxygen sensor 14, and an air float meter 24 carries out a feedback control to the fuel injection amount of a fuel injection valve 5 according to the air-fuel ratio detected by the oxygen sensor 14, when a specific feedback control condition is accomplished. And in this case, the control speed of the air-fuel ratio feedback control is converted by converting an integration constant used for the integration control to the lean side according to the engine operating condition at that time. And when the control speed is higher than a prescribed value, in an air-fuel ratio feedback control in this case, the ignition timing is converted to the speed advance side, and the combustion is stabilized.

The key reference information on a single level consists of 8 bits, and higher 5 bits correspond to 5 types of keys. Bits '1' requires and '0' does not require the relevant keys respectively. When a file is selected through a reader/writer device, the key reference information stored in the directory (a) is outputted to the reader/writer device. Thus, the reader/writer device can identify a specific key for execution of a specific instruction of the selected file based on the key reference information.

Title: Vortex pump
Inventor: HARII PIITAA UEINRIBU
IPC: F04F1/18
Filed: 1985-06-05
Abstract: A pump (10) is provided with a vortex generaing member (35) which rotates about a central axis (32) to generate a vortex column (30) of liquid which has a rotary velocity and which is directed to the pump inlet (15). At the pump inlet, this energy is dissipated into the ambient liquid (16) causing an inward flow of liquid swirling in an opposite direction into and through the pump inlet (15) for discharge through a pump outlet (18). The preferred vortex generating member (35) has a plurality of outer liquid inlets (42) leading to passageways (48) of reducing cross section which causes the liquid to increase in velocity as the liquid flows radially inwardly toward the axis (32) and liquid streams are combined tangentially at the axis. The pump is particularly useful for pumping liquids with particulate content and overcomes the problem of abrasion between moving parts by such matter.

Title: Ceramics green sheet and formation of pattern thereon
Inventor: MASAKI YOSHIKI
IPC: C04B35/622
Filed: 1995-05-22
Abstract: PURPOSE:To form a pattern on a ceramics green sheet using photosensitive paste by providing a photo-set layer of a photosensitive resin compsn. on a ceramics green sheet substrate. CONSTITUTION:A photosensitive resin compsn. is used in the formation of the photo-set layer on a ceramics green sheet substrate. The photosensitive layer composed of the photosensitive resin compsn. is a layer becoming insoluble by the irradiation with active light. As an example of the photosensitive resin compsn., a compsn. prepared by mixing a functional monomer or oligomer having one or more unsaturated group in one molecule thereof with a proper polymer binder is designated. As a result of the sufficient curing of the photosensitive resin compsn. layer with ultraviolet rays, the chemical resistance or solvent resistance of a sheet is enhanced and the reaction with an org. solvent in photosensitive paste is almost eliminated and an undeveloped part is perfectly removed. By this constitution, a good pattern can be formed on the sheet using photosensitive paste.

Filed: 1984-06-14
Abstract: PURPOSE:To save the current consumption of an electromagnetic driving shutter and to stabilize the accuracy of the shutter by forming a blade holding means for mechanically holding a shutter blade at a travelling completing position and stopping power supply to an electromagnetic driving source.
