Title: Semiconductor circuit
Inventor: MATSUO RYOSUKE
IPC: H03K5/08
Filed: 1987-03-25
Abstract: PURPOSE:To obtain a large amount of noise proof at a state where an operation margin is maintained, by preferring a noise proof quantity in a period that a power source noise is generated, and preferring the operation margin for an input signal in another period. CONSTITUTION:In addition to a transistor Q5 whose conduction is controlled corresponding to the potential of an output node, an N-type MOS transistor Q6 is provided additionally. Since the transistor Q6 is also turned on in the period that power source potential and reference potential fluctuate, a threshold voltage drops in the period and malfunction can be prevented from being generated. Since the transistor Q6 is turned off in the period other than that, an input/ output characteristic at that time becomes the one in which the operation margin for specification is preferred.

Title: Picture processing system
Inventor: UKEGAWA TAKESHI
IPC: H04N1/409
Filed: 1983-04-23
Abstract: PURPOSE:To eliminate the effect of dirt of background onto a picture by changing a threshold value for binary-coding through a binary-coding data corresponding to a preceding picture element. CONSTITUTION:A scanner 1 outputs an analog picture element signal AP corresponding to the density at each picture, the signal is converted into a digital signal DP by an A/D converter 2 and stored in a matrix register 3. A correcting value E' subject to MTF correction at an operating device (spatial filter) 4 is compared with a correcting threshold value SL' outputted from an adder 7 by a digital comparator 5 to output a binary-coding data BD. When the correcting value E' is changed, the correcting threshold value SL' is changed into a value adding the inverted value ''1'' of the binary data BD to the threshold value SL' from the step next to the step judged as white data. While a black picture element is detected from the step next to the step where the correcting value E' is judged as black data, since the inverted value of the binary data BD is ''O'', the correction threshold value is made to a value being identical to the threshold value.

Title: Brake control device for electric automobile
IPC: B60T8/172
Filed: 1992-03-27
Abstract: PURPOSE:To perform suitable realization of ABS control even at a split muroad. CONSTITUTION:In a state that either right or left wheel is brought into a lock tendency at 100 and 102, an increase gradient dp'/dt of an oil pressure by pedal operation is compared with a boosting gradient dp/dt at 110 and 120, and based on either of the gradients, an oil pressure is increased at 114 and 116. The increase of an oil pressure during a time in which after one wheel is brought into lock inclination, the other wheel is brought into lock inclination is relaxed and deflection of a car body is easily prevented from occurring through the steering action of a driver. Further, since motor torque during ABS is used by not only the regeneration side but also the powering side, coping with a low mu road is practicable.

Abstract: PURPOSE:To decrease the number holes of the outer peripheral surface of a bearing member not to be blocked up so as to improve assembling efficiency by providing an exhaust means for communicating the respective spaces with each other between the space between bearing members and the external space on the bearing member side. CONSTITUTION:In a bearing device, a turbine blade nozzle 11 blows off air supplied from an air hole 10b of a housing 19 from a gas supply outlet 11a toward a turbine blade 7 to rotate a rotary shaft 1. A bearing nozzle 12 blows off gas supplied from the air hole 10a from a gas supply outlet 12a toward a shaft part 6 to support the rotary shaft 1 in the radial direction with static pressure, and the gas flows along the shaft part to apply static pressure to a collar part 3 so that the rotary shaft 1 is supported in the axial direction. Air jetted from the nozzles 11, 12 is discharged to the outside through an exhaust hole 29 piercing a bearing nozzle member 18.
