Title: Method and device for bus arbitration of multiprocessor system
Inventor: TAN KUAN GUEN
IPC: G06F13/364
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To give equal chances to access a common bus to all processors by allowing a next request-side device to access the bus when the device having top priority requests no bus access, and giving the top priority to the device which is logically adjacent to the next request-side device. SOLUTION: Work stations 70, 72, and 74 are coupled with BUCs (bus unit controller) 30, 32, and 34 by PCI buses 31, 33, and 35 of IBM respectively. The BUCs 30, 32, and 34 enable a communication between the work stations 70, 72, and 74 and a memory controller 20 through a 6XX-MX input/output bus 40. A memory controlled by the memory controller 20 can be accessed with request signals from the work stations 70, 72, and 74. An arbitration logic circuit 10 arbitrates requests from the BUCs 30, 32, and 34 by sending an arbitration signal to the BUCs 30, 32, and 34 by an arbitration signal bus 50.

Title: Developing device
Inventor: SAKAGUCHI MIKIO
IPC: C04B35/565
Filed: 1995-03-15
Abstract: PURPOSE: To obtain a developing sleeve having excellent sliding characteristics, proper electric conductivity for application of developing bias voltage, and high durability by constituting the sleeve of a silicon carbide-carbon composite material. CONSTITUTION: This sleeve consists of a silicon carbide-carbon composite material. The amt. of carbon is 10-50 pts.wt. to 100 pts.wt. of silicon carbide. The domain diameter of the carbon included is usually <=20μm, and preferably 0.1 to 10.0μm. If the domain site exceeds 20μm, sliding property is hardly obtd. or it becomes difficult to process the material into specified surface roughness. It is preferable that in the intensity curve of laser Raman spectroscopy, the peak area ratio of the crystalline phase to the amorphous phase carbon is 1.00-10.00. If the peak area ratio is <1.00, the sliding characteristics decrease with increase in the amt. of the amorphous phase. If the ratio exceeds 10.00, graphitization proceeds, which improves the sliding characteristics but deteriorates the composite characteristics.  The surface of the developing sleeve (sliding surface) is controlled to have <=35μm flatness and 0.01-5μm center line average roughness Ra.

Abstract: PURPOSE: To ensure the arm to be moved even if the amount of displacement of the stylus exceeds the set value of the hysteresis comparator, by compulsively inverting the output of the said comparator after the drive of arm drive motor.  
     CONSTITUTION: The amount of displacement of the pickup stylus is detected from the coil movement circuit 5, the amount is compared with the set value of the comparator 22, and if the amount exceeds the set value, the output of the differential amplifier 22A inverts from low to high level. This inverted output turns on the monostablemultivibrator 23 for an arbitrary time to drive the motor 16 for the arm drive. Further, when the inverted output of the monostable multivibrator 23 is inverted from low to high level, the output of the differential amplifier 22A is compulsively inverted to a low level. With this operation, even if the amount of displacement of the pickup stylus exceeds the set value of the said comparator 22, the problem of nonmovement of arm can be solved.

Title: Flash discharge light emitting device responding to luminosity of field
Inventor: TAKEMATSU YOSHIYUKI
IPC: G03B15/05
Filed: 1980-06-26
Abstract: PURPOSE:To prevent overexposure automatically by stopping the oscillations of the DC-DC converter of a charging source for a main capacitor on detecting the luminosity of a field exceeding a prescribed value. CONSTITUTION:When the luminosity of a field exceeds a prescribed value, the resistance of a photoconductive element 7 increases to turn off a transistor 3, so that an oscillation transformer 2 forming a DC-DC converter will not oscillate. Therefore, a main capacitor 12 is not charged, and a flash discharge tube 18 never flashes. On the other hand, if the luminosity of the field exceeds the prescribed value while the  discharge tube 18 is flashing to stop the oscillations of the transformer 2, capacitors 11 and 14 are discharged via a resistance 17 to turn off a neon lamp 9. Simultaneously, a trigger voltage obtained through a boosting transformer 15 is vanished to stop the flashing of the discharge tube 18, thus preventing over-exposure automatically.
