Title: Dynamic pressure bearing structure
Inventor: SHIMADO KOJI
IPC: G02B26/10
Filed: 1990-03-22
Abstract: PURPOSE:To reduce the number of parts, facilitate assembling work and improve durability by setting the outer diameter of the thrust bearing face formed of the end face of a supporting shaft to be specific times longer than the length of the radial bearing face of a rotor. CONSTITUTION:In this dynamic pressure bearing structure, the end face of a supporting shaft 5 is formed into a thrust bearing face, and the outer diameter of the thrust bearing face of the supporting shaft 5 is set to be two to five times longer than the length of the radial bearing face of a rotor 7. The rotation of the rotor 7 in the specified direction is started by the mutual action between the magnetic field generated to each coil 12 on the basis of the current application control of each coil 12 and the magnetic field of a magnet 10. In association with this rotation, air in a case 1 is forcibly led in between the supporting shaft 5 and the rotor 7 through air lead-in grooves 16, 17 to form an air bearing. Then the rotating speed of a polygon mirror 8 on the rotor 7 is increased and kept to the specified rotating speed, so that the upper end face area of the supporting shaft 5 is enlarged to support the whole rotor 7 stably through a thrust bearing body 14.

Title: Reverse conductive gto thyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/744
Filed: 1985-04-08
Abstract: PURPOSE:To enhance the turning OFF function by forming a high density impurity region having a reverse conductive type to a base layer and the prescribed diffusing depth in the base layer between the surface of a semiconductor substrate and the first P-N junction of a separating region, thereby providing sufficient reverse voltage between the gate and the cathode of a reverse conductive GTO thyristor. CONSTITUTION:A high density N<+> type region 8 is formed by diffusing in a depth D of a P-type base layer 10 from the surface 9 of a semiconductor substrate so as not to arrive at the first P-N junction 12 between the layer 10 and an N-type base layer 11 in the vicinity contacted at a boundary with a diode 2 of a separating region 3. The interval between the region 8 and the P-N junction is so formed that the depth d of the region 8 is large and the resistance increases as the interval becomes narrower and the resistance value alters with respect to the width (t) of the region 8. When a reverse voltage is applied between the gate electrode and the cathode electrode of a GTO thyristor, sufficiently high reverse withstand voltage is obtained, and a turn OFF is performed. The interval between the region 8 and the junction 12 is necessary to be decided to the optimum value from the relationship between the reverse voltage between the gate and the cathode of the thyristor and the forward withstand voltage.

Title: Output controller of compound power plant
Inventor: MASUYAMA HIDEO
IPC: G05B13/00
Filed: 1983-04-28
Abstract: PURPOSE:To ensure a stable operation of a compound power plant with high efficiency and low load by supplying the generated gas pressure signal in response to the operating state of a fuel gas base to obtain the corresponding optimum number of operating units and tripping other power generating units. CONSTITUTION:When the gas pressure GP has a drop at a compound power plant, a unit trip selecting circuit 5 calculates the number of power generating units which the power plant has the optimum effciency in response to the pressure GP. Then the excess number of operating units are tripped by drivers 3-1- 3-n. At the same time, a target load command signal TL is also run back. Here the output mw of the power generating unit that is selected by the circuit 5 and tripped is reduced down. Therefore, the output request signal RD to be supplied to unit output control parts 12-1-12-n is not so much deteriorated as the efficiency of the power generating unit. Thus the output request to an operating power unit belongs to an output request area of the operating state of high efficiency.

Filed: 1988-03-30
Abstract: PURPOSE:To control air fuel ratio in acceleration to a desired value even if the concentration of alcohol in the fuel varies during acceleration, by correction- setting the additional fuel injection quantity in accordance with the concentration of alcohol after variation. CONSTITUTION:When the engine acceleration operation state is detected on the basis of the variation of the opening degree of an intake throttle valve 15 which is detected by an opening degree sensor 38, a control unit 40 sets the additional fuel injection quantity in the additional injection which is carried out separately from the normal injection, on the basis of the acceleration operation state and the concentration of alcohol which is detected by an alcohol sensor 39. Then, the additional injection is controlled according to the additional fuel injection quantity. When the concentration of alcohol is varied during the additional injection control after the setting of the additional injection quantity, the additional fuel injection quantity is correction-set in accordance with the concentration of alcohol after the variation. Therefore, a desired additional fuel injection quantity is obtained, and the air-fuel ratio in acceleration can be controlled to a desired value.
