Title: Splicing tape for magnetic tape
Inventor: SUZUKI SHINJI
IPC: G11B5/627
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To suppress the deformation of a magnetic tape and to reduce noise by forming a pressure sensitive adhesive layer having a specified thickness and a specified Young's modulus on the surface of a polyethylene naphthalate film or a poly-p-phenylene terephthalamide film having a specified thickness and a specified Young's modulus. SOLUTION: A base film made of a polyethylene naphthalate film or poly-p- phenylene terephthalamide film is required to have 3-10μm thickness. In the case of <3μm thickness, such strength as to withstand tension at the time of running is not ensured and splicing function cannot well be satisfied. In the case of >10μm a small-sized high density magnetic tape is liable to deformation. A pressure sensitive adhesive layer is formed on the surface of the base film. The pressure sensitive adhesive may be selected from among known various adhesives if the layer has 0.8-10kg/cm<2> , preferably 1.2-7kg/cm<2> Young's modulus.

Title: Output control circuit
Inventor: KAWAI SHUICHI
IPC: G06F1/26
Filed: 1991-12-18
Abstract: PURPOSE:To obtain the output control circuit which can maintain a stable output control signal even when a power supply potential rises. CONSTITUTION:This output control circuit is provided with a charge pump part 6, which increases a charge potential 5 to a power supply potential 4 with a GND as a reference according to a transmitting clock signal 1 only when an output control signal 2 is active, and a capacitor 7 between the charge potential 5 and the GND. By inputting an output signal 8 to the gate of an N-ch output buffer 9, an output is controlled and the state of an output terminal 10 is decided. After the power supply potential starts rising, since no transmitting clock signal 1 is generated until the potential reaches an internal circuit stable voltage, the charge pump part 6 is not operated and no electric charge is supplied to the charge potential. Therefore, even when the output control signal is instable, the charge potential and the output signal are kept at the GND by the capacitor. Thus, the N-ch output buffer is always turned off, and the output terminal can stably maintain a high impedance state.

Title: Method for dividing inspecting sequence of semiconductor integrated circuit and method for generating the insecting sequence
Inventor: HIRAOKA TOSHIHIRO
IPC: G01R31/28
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To easily divide a large scale fault inspecting sequence into a plurality of divided inspecting sequences, even in a partial scan designed or non-scan designed semiconductor integrated circuit by adding a state transition sequence transitable to an identifying inner state identified, so that a second divided inspecting sequence becomes significant for a head of the second divided inspecting sequence. SOLUTION: An internal state decided by a combination of input values from external inputs is identified, so that second divided inspecting sequences of a rear side which is divided become significant, thereby to decide the identified inner state, and thereafter the state is validated so as to become the identified inner state from an initial state. Then, after a state transition sequence has transited to the identified inner state is generated, the transition sequence is added to the head of the second divided inspecting sequences. Thus, even if a fault simulation is conducted by using the second divided sequence, the inner state of the first divided sequences when the fault simulation is finished agrees with that of the second divided sequences at the start of fault simulation.

Title: Circuit for protecting power supply feeding apparatus from overcurrent
Inventor: RI JUKICHI
IPC: H02H3/08
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To recover a power supply feeding apparatus to its normal state without a shutdown such as one caused by an overcurrent as to make it unrecoverable by recovering in a short time its circuit protecting function from the overcurrent through the normal recovery of the overcurrent. SOLUTION: The output voltage of an amplifying portion 34 so applied to a control portion 10 as to control it is discharged by a fifth resistor R5, a capacitor C1 connected across the output terminal of an amplifying element IC1, and a ground. Therefore, since the time wherein the applied output voltage of the amplifying portion 34 to the control portion 10 is charged and discharged by the capacitor C1 is controlled according to a time constant value determined by the fifth resistor R5 and the capacitor C1, the output of the amplifying portion 34 is delayed, resulting in delay of an overcurrent protection operation caused by an overcurrent. As a result, no shutdown of a power supply feeding apparatus caused by the overcurrent is performed at once to delay it by a predetermined time specified through the fifth resistor R5 and the capacitor C1. Therefore, when the overcurrent has recovered within a range delayed by the predetermined time, the apparatus recovers to its normal state.

Abstract: PROBLEM TO BE SOLVED: To make an interval between microstrip lines smaller than the limit of the process of electrode formation, and to increase the degree of connection by making the interval of between the surface parts smaller than the interval between the parts brought into contact with a dielectric substrate between the two microstrip lines. SOLUTION: Microstrip lines 3 and 4 are mutually connected by an electromagnetic field, and the cross-section shape is like a trapezoid with large width at the surface part and small width at the part brought into contact with a dielectric substrate 2.
