Title: Multi-cylinder two-cycle internal combustion engine
Inventor: HIROSE KATSUHIKO
IPC: F02B75/02
Filed: 1988-06-16
Abstract: PURPOSE:To prevent the occurrence of self-ignition by controlling air fuel ratio as that the air and fuel mixture of a primary cylinder group is enriched more than that of the theoretical ratio, the air and fuel mixture of the secondary cylinder group is lean and the above-mentioned air fuel ratios of each of cylinder groups are set to the theoretical air fuel ratio. CONSTITUTION:The cylinders of a multi-cylinder two-cycle internal combustion engine are divided into a primary cylinder group 100 and a secondary cylinder group 101 and the air fuel ratio of the cylinders in the primary cylinder group 100 is controlled to be richer than the theoretical air fuel ratio by a richness control means 102. The air fuel ratio of the cylinders in the secondary group 101 is controlled to be leaner than the theoretical ratio by a leaning control means 10. The overall air fuel ratio of the internal combustion engine, that is, the average air fuel ratio of the cylinders included in the groups 100 and 101 is controlled to an approximate theoretical air fuel ratio by an average air fuel ratio control means 104. So the self-ignition may be prevented and the purification operation of a three-way catalyst placed in an exhaust system be maintained to a high level to effectively remove the harmful content inside exhaust gas.

Abstract: PROBLEM TO BE SOLVED: To stably support a spindle member in an axial direction and a diameter direction with a dynamic pressure groove formed on a nearly conical surface by forming the groove for generating dynamic pressure so as to generate peak of dynamic pressure at a plurality of positions of the axial direction. SOLUTION: A conical part 1 is provided with first bending dynamic pressure grooves 6 bent in a circumferential direction on the large diameter side of the outer peripheral surface 1c of the conical part 1, and second bending dynamic pressure grooves 7 bent in a circumferential direction on the small diameter side of the outer peripheral surface 1c. The first and second bending dynamic pressure grooves 6, 7 are arranged in parallel with each other at a prescribed clearances. In the conical part 1, peak of dynamic pressure generated by rotation of a spindle member 3 are generated in the vicinity of an angle 6a of the first bending dynamic pressure groove 6 and in the vicinity of the angle 7a of the second bending dynamic pressure groove 7.  Since two dynamic pressure peaks are generated on positions which are separated for a prescribed distance from each other in the axial direction, resistance force against a moment load is enlarged so as to stably support the spindle member 3. It is thus possible to prevent oscillation of the spindle member caused by external disturbance on rotating.

Abstract: PURPOSE:To reduce the delay in the access to the cell memory information, by adding a transistor to the final stage gate circuit and decreasing the delay in the trailling of work line at the transistion of status. CONSTITUTION:A transistor Q30 controlled with a signal -CS' is added to the final stage gate circuit G3, and the circuit G3 constitutes an NOR gate which takes the output N2 of the gate circuit G2 and the signal -CS' as an input.

Title: Controller for electric rolling stock
Inventor: TAKAHARA HIDEAKI
IPC: B60L3/00
Filed: 1986-06-26
Abstract: PURPOSE:To eliminate an excess charging current to a capacitor when a power is reapplied by stopping a converter and an inverter before a capacitor voltage drops when a power source is interrupted. CONSTITUTION:When a power supply is stopped during the power drive of an electric rolling stock an inverter IN is powered by the charge of a capacitor C and continues operating. In this case, no power is supplied from a converter CN. When a capacitor voltage drops and the detected value of a voltage detec tor VD reaches a reference voltage V2 or lower, a stop command is output from a comparator REF2 to a converter controller SC and an inverter controller IS. When the interruption of a power source is long and the capacitor voltage drops to a reference voltage value V1, a command for opening a contactor KS is output from a comparator REF1. Thus, it can prevent an excess charging current from flowing when a power is reapplied.

Filed: 1987-06-15
Abstract: PURPOSE:To measure humidity highly accurately in a broad range, by providing a porous layer at the outer surface part of a core, and providing a reflecting film, which is formed at one end surface of the core, reflects incident measuring light inputted from the other end surface and returns the light to the other end surface. CONSTITUTION:The moisture sensitive part of a sensor is positioned in a gas to be measured. Measuring light is inputted into a core through a rear end surface 9 of the core 1. Then, the measuring light repeats reflection from the interface between the core 1 and a clad layer 2. The light is propagated and reaches the moisture sensitive part. A porous layer 3 adsorbs moisture in the gas to be measured. The measuring light reaching the moisture sensitive part is subjected to the effect corresponding to the amount of the adsorbed moisture in the porous layer 3 when the light is reflected from the interface between the core 1 and the porous layer 3. The scattering amount of the measuring light at the interface between the core 1 and the porous layer is changed. After the measuring light is reflected from a reflecting film 5, the light undergoes intensity change at the interface between the core 1 and the porous layer 3 again. Then, the light returns to the rear end surface 9. The outputted reflected light is separated and measured. Thus, the relative humidity of the gas to be measure is detected.
