Title: Test-and-set system
Inventor: YANO HIDEYUKI
IPC: G06F15/16
Filed: 1988-05-20
Abstract: PURPOSE:To attain an access carried out by a normal processor in case an area is locked by a faulty processor by writing the detecting result of troubles into a fault register set in a main memory control unit after diagnosing each processor via a diagnosing processor. CONSTITUTION:A diagnosing processor 30 diagnoses processors 40, 41... to detects their faults and writes these detecting results into a fault register in a main memory control unit 10. While the unit 10 receives a test-and-set TAS request from a processor 40, for example, and reads a TAS flag out of a main memory 20. In this case, if the flag is set at a processor whose fault is recorded into the fault register, this fact is informed to the processor 40. When the flag is not set, a TAS flag where a bit corresponding to the processor 40 is set is produced for replacement of the flag set in the memory 20. Thus an access can be carried out by a normal processor when an area is locked by a faulty processor.

Title: Liquid jetting device
Inventor: SADAMURA SHIGERU
IPC: B41J2/16
Filed: 1985-06-07
Abstract: PURPOSE:To obtain electrodes having sufficiently great bonding strength with a piezo-electric ceramic tube and free of damage to the original expansible actin of the piezo-electric ceramic tube by a method in which the thickness of the conductor-soldered portion of the electrode is made greater than that of the other portion. CONSTITUTION:Electrodes 4a and 4b are connected with conductors 5a and 5b by soldering, and the conductors 5a and 5b are connected to a power source. The thickness of the portions 6a and 6b where the conductors 5a and 5b are soldered is made greater than that of the other electrode portion, and thereby the bonding strength between the piezo-electric ceramic tube and the electrodes 4a and 4b is so raised that the electrode portion is not separated even when the conductors 5a and 5b are soldered to the portions 6a and 6b. The thickness of portions 4a and 4b where the conductors are not connected in the electrodes can thus be made smaller to 1mum or less. Therefore, since the expandable action of the tube 3 is not interrupted, it is possible to cause great displacement even at low voltage.

Title: Device and method for interpolating picture data, and medium for recording picture data interpolating program
Inventor: TOMIYAMA TADAO
IPC: G06T3/40
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To eliminate waste and to attain an efficient interpolation processing by extending the picture element with the prescribed interpolation processing through the use of picture data of a picture element in an applying area if not only for the background picture element so as to extend and executing the simple interpolation processing concerning the background picture element if only for the background picture element, according to a decision result. SOLUTION: A virtual plotting means C1 discriminates the background picture element from a foreground picture element and executes plotting in a virtual area corresponding to an actual area. A picture data reading means C2 reads picture data of the picture elements belonging to the respective areas while successively changing the object area from the virtual area. A background picture element decision means C3 judges whether the picture element belonging to the read-out area is only the background one or not. Based on the result, a picture element interpolating means C4 interpolates the picture element by the prescribed interpolation processing through the use of picture data of the picture element in the applying area unless the picture element is only the background one.  On the other hand, the picture element interpolating means C4 executes the simple interpolation processing concerning the background picture element in the case of only the background picture element, and a picture data output means C5 outputs it as picture data.

Abstract: PURPOSE:To enhance the shearing strength of a friction disk while keeping its bending strength, by thrusting a needle assembly or the like to a lamination of woven or knit carbon fiber fabrics, and providing a carbon matrix to conjoin the fabrics to each other. CONSTITUTION:A needle assembly, a spike roller, a needle roller or the like is applied to a lamination of woven or knit carbon fiber fabrics to entangle the fibers of the layers of the lamination with each other. After being impregnated with a thermosetting resin, the lamination is baked under pressure to carbonize the impregnated resin to fill the voids of the lamination. The shearing strength of the lamination is thus enhanced while its bending strength is maintained.

Title: Method and apparatus for evaluating brain wave
Inventor: NISHIMURA TOSHIHIRO
IPC: A61B5/0476
Filed: 1988-05-23
Abstract: PURPOSE:To estimate a sudden death syndrome beforehand by detecting the just before of an apneic state at a sleeping time, by evaluating the frequency component within a specific range of a brain wave spectrum obtained from brain wave data by overlap split analysis due to high speed Fourier transform. CONSTITUTION:The brain wave data detected from a newborn 11 by a brain wave detection part 12 is stored n a memory device 14 as timewise continuous data through an A/D converter 13 and said data is subjected to overlap splitting by a microcomputer 15 so that the number of data overlap with each other and the waveform of the brain wave of each section obtained by overlap splitting is subjected to frequency analysis by high speed Fourier transform to obtain a stepwise shifted brain wave spectrum. This brain wave spectrum is operationally processed within a real time and an increase and decrease in a frequency component of 3-12Hz is evaluated to make it possible to detect a state before apnea at a sleeping time. This evaluation can be performed, for example, by detecting that the amplitude of a brain wave spectrum is 0.05V or less. By an apparatus for automatically analyzing this detection, information becomes possible several minutes before apnea at a sleeping time is generated.
