Title: Magnetic marker for article discrimination
Inventor: KATSUYAMA TERUSHI
IPC: G06M7/00
Filed: 1992-06-17
Abstract: PURPOSE:To prevent the degradation of detection precision by making one set of plural magnetic thin wires having the same coercive force and arranging plural sets of magnetic thin wires, which are different in coersive forces, in parallel with the direction of an applied magnetic field. CONSTITUTION:Three pairs of magnetic thin wires, namely, six thin wires in total are attached on a fixed plate 12 made of plastics or the like. That is, the coersive force of the pair of magnetic thin wires 2a1 and 2a2 is H1, and that of magnetic thin wires 2b1 and 2b2 is H2, and that of magnetic thin wires 2c1 and 2c2 is H3, and these three pairs of magnetic thin wires are arranged at proper intervals. Therefore, an induced voltage from a detecting coil due to the change of the magnetic flux of magnetic thin wires is increased several times in comparison with the individual use of magnetic thin wires whose coersive forces are different from one another. Thus, the distance between a magnetic marker and the detecting coil can be made long, and the detection precision of article discrimination is not degraded even if the length of magnetic thin wires is limited by the size of an article.

Title: Feedback controller for optical recording and reproducing device
Inventor: DEGUCHI TOSHIHISA
IPC: G11B7/09
Filed: 1988-06-23
Abstract: PURPOSE:To reduce the manhour required for the control and to attain the reduction of the production cost by providing an offset correcting means which outputs an offset correction signal to a control amplifier in order to set the control signal received from the control amplifier at a prescribed level. CONSTITUTION:The level of an offset correction signal is set so that the control signal received from a control amplifier 33 is set at a prescribed level via an offset correcting means 37 as long as the irradiation state of the light beam is normal to a recording medium. Thus it is surely prevented that the control signal of the amplifier 33 includes the DC offset even when the offset of the amplifier 33 itself and the unbalance of the power supply voltage, etc., differ according to the variance of each amplifier 33 and power unit. Then the information is surely recorded, reproduced and erased to the recording medium. Thus it is possible to reduce the manhour required for the control and also to reduce the production cost. In addition, the variance of performance can be avoided for each device.

IPC: G03G15/09
Filed: 1988-06-28
Abstract: PURPOSE:To regulate thickness without exerting adverse magnetic influence on a developer and without exerting adverse influence on the triboelectrified charges of the developer by forming a thickness regulating member of non- magnetic material and specifying the volume resistivity of the surface of the member. CONSTITUTION:The cylindrical thickness regulating member 33 regulating the thickness of a developer layer is formed of the nonmagnetic material, and its surface volume resistivity is <=7muOMEGA.cm. Since thickness can be regulated without exerting adverse magnetic influence on the developer 36, satisfactory development free from density lack and density irregularity can be accomplished with magnetic toner. Moreover, even if the friction contact of the surface of the thickness regulating member 33 with the developer 36 generates triboelectrified charges, they are diffused and averaged on the surface of the thickness regulating member 33; therefore the distribution of the triboelectrified charges in the developer layer is prevented from being influenced adversely, and the satisfactory development free form density irregularity can be attained.

Title: Test pattern generation method for combinational logic circuit
Inventor: KOUDA HIROSHI
IPC: G06F17/50
Filed: 1992-06-17
Abstract: PURPOSE:To make it possible to generate a test pattern efficiently for a short time by assigning to a head signal line in a combinational logic circuit a part of input variables of logical functions that are used for a shared binary decision diagram(BDD) and reducing the number of input variables thereby. CONSTITUTION:Logical functions that are specified respectively by signal lines B3 to B6 against input variables assigned to external input lines B1 and B2 and a head signal line HL, are stored as a shared BDD. Then, test pattern generation processing is started for stuck-at fault on internal signal lines B3 and B4 and the signal line HL. As an example of signal line B3, when assumed stuck-at fault is transferred to an external output line B5, a logical function XOR on an output line B5 during normal and out-of-order status on the signal line B3 is searched, and an input variable in which a logical function specifying the XOR becomes one is searched as a local test pattern. Further, after searching the value on external input lines A1-A3 that satisfies the value of the signal line HL in this pattern, these values are combined with the values on the input lines B1 and B2 so as to obtain a test pattern for entire combinational logic circuit for detecting stuck-at fault of the signal line B3.
