Title: Liquid crystal display element
Inventor: ITO HIROSHI
IPC: G02F1/1335
Filed: 1987-11-24
Abstract: PURPOSE:To switch and display necessary display colors of three colors through five colors based on a white color as a reference by forming interdigitally a stripe-like electrode of a two-color portion of three colors corresponding to stripe-like color filters red, green and blue, respectively, and a stripe-like electrode of the other one color, and forming a common electrode on the opposed substrate. CONSTITUTION:As for three pieces of stripe-like electrodes corresponding to red R, green G and blue B, two pieces among them are connected in common and by a simple interdigital constitution of two pieces-to-one piece, a pattern can be drawn out. At present, a segment electrode 5G and 5B are connected in common and taken out as a segment GB. A segment 5R is taken out as a segment R as it is, and two kinds of segments constitute one display segment like the teeth of a comb. On the other hand, a common electrode 4 determines a display segment shape. In this state, a voltage applied to the common electrode 4 and between the segment R and the segment GB is controlled. In such a way, by a simple electrode pattern constitution and a control, display colors of white, blue green and red can be switched arbitrarily.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/64
Filed: 1988-11-22
Abstract: PURPOSE:To obtain the magnetic recording medium having a good head touch by forming a perpendicularly magnetized film of a Co alloy directly on a high- polymer film in which a carbon black is incorporated. CONSTITUTION:The perpendicularly magnetized film 3 of the Co alloy is directly formed on the high-polymer film 1 into which the carbon black 2 is incorporated. The surface ruggedness formed with the carbon black as a nucleus is not steep in this way and, therefore, the degradation in the crystallinity generated in the initial growth of the thin film is lessened and the film thickness increase is minimized. The rigidity of the high-polymer film is increased by the incorporation of the carbon black and the touch with a rotary head at a high speed is assured. Further, the thermal conductivity and electrical conductivity of the film are improved at the time of the thin film formation and, therefore, the nonuniformity generated in the thin film by the charge particles is hardly admitted and since the good noise level is obtd., the high-density recording performance is satisfied.

Title: Cpu system
Inventor: MOTOMURA KAZUMASA
IPC: G06F11/08
Filed: 1989-11-14
Abstract: PURPOSE:To send an ACK (acknowledge) signal from only an accessed I/O unit by providing each I/O unit with an ACK control part in the system which consists of a CPU and plural I/O units and shares an ACK line. CONSTITUTION:Each I/O unit 2 is provided with an ACK control part 4, and a CPU 1 and respective control parts 4 are connected by an ACK line 3 and an ACK control line 5. When the CPU 1 accesses each I/O 2, it sends a code corresponding to the I/O 2 through the control line 5, and only the control part 4 of the unit corresponding to this code sends the ACK signal to the CPU 1 through the ACK line 3 after the end of processing. Thus, the ACK signal is prevented from being sent to the CPU 1 from the I/O unit which does not detect the code corresponding to the unit itself. That is, multiple generation of the ACK signal is prevented regardless of erroneous access due to a bug or noise, and the CPU 1 can continue the normal operation.

IPC: H01J47/02
Filed: 1990-11-01
Abstract: PURPOSE:To make the reading of a normally measured value easy without providing the vibrationproofing, etc. to a ionization chamber by holding the value of a signal with compensation into the value of the signal at the prescribed time when the magnitude of one side of several vibrations arising in the ionization chamber becomes the value at the prescribed time or more. CONSTITUTION:A vibration detector 28 is fixed to the outside of an ionization chamber 9, detects the vibration arising in the ionization chamber 9 and outputs the vibration signal 28a according to the magnitude of the vibration. A signal delay element 29 delays the input detecting-signal 17a only the prescribed delay time and outputs a delay detecting signal 29a. A signal output element 30 to which the signals 29a and 28a are input outputs the signal 29a as it is, as a measured signal 30a when the signal value V of the signal 28a is smaller than the prescribed value. The element 30 holds the value of the signal 30a in the value of the signal 29a only the elapsed time when the signal value V is larger than or equal to the prescribed value at a certain time, and outputs again the signal 29 as it is, as the 30a from the elapsed time on. A tritium gas monitor 31 has the time set so that the vibration settles within the holded time and the signal 29 becomes a signal state without influence of the vibration even if the vibration whose the signal value V becomes not less than the prescribed value arises in the ionization chamber 9.
