A discharge accelerating unit which accelerates a discharge of a capacitive load (floating capacitor C1) of a signal line when a positive polarity input gradation voltage DAC(P) decreases is provided for a positive polarity operating circuit. A charge accelerating unit which accelerates a charge of a capacitive load (floating capacitor C2) of a signal line when a negative polarity input gradation voltage DAC(N) decreases is provided for a negative polarity operating circuit. Good characteristics can be obtained irrespective of a switching period of the positive polarity operating circuit and the negative polarity operating circuit and luminance levels of adjacent dots. The number of devices which are added by the invention can be minimized.

A method of testing a performance of the HGA has a step of writing information from the at least one thin-film magnetic head element onto a magnetic disk with driving the actuator for displacement by applying an alternating drive signal to the actuator, a step of reading out the information of at least one rotation of the magnetic disk by the at least one thin-film magnetic head element without driving the actuator for displacement, a step of storing the information read-out from the magnetic disk as a read-out information along a disk-rotating direction, a step of moving the HGA toward an off-track direction by a predetermined distance, a step of repeatedly executing the reading, storing and moving steps to obtain two-dimensional read-out information along the disk-rotating direction and the off-track direction, and a step of determining, from the two-dimensional read-out information, an off-track position where the read-out information becomes maximum at each position along the disk-rotating direction, the determined off-track positions being recognized as displaced positions of the actuator in response to the applied alternating drive signal.

A channel control apparatus is arranged in a plurality of nodes on a source as a transmission side and at a node on a sink as a reception side, and changes a bandwidth of virtual concatenation (VC) between the nodes on the source and the sink using link capacity adjustment scheme (LCAS) information. The channel control apparatus includes a VC/LCAS main controller that sets member use-request information for the VC or member usable information for the VC in the LCAS information, and changes the member of the VC between the nodes on the source and the node on the sink.

A Head Arm Assembly includes a head slider having at least one head element, an arm member for supporting the head slider at one end section, an actuator, mounted to the other end section of the arm member for rotationally moving the arm member in a direction substantially parallel with a recording medium surface around a horizontal rotation axis of the arm member, a load generation unit for generating a load for energizing the head slider in a direction toward the recording medium surface by rotationally moving the arm member in a direction substantially orthogonal to the recording medium surface around a vertical rotation axis, and a limiter unit for restraining the arm member from rotationally moving more than a predetermined limit around the vertical rotation axis in a direction away from the recording medium surface.

A complementary signal generator, for outputting complementary positive-phase and antiphase signals that vary between a first logical value and a second logical value, which includes a signal forming unit for outputting a positive-phase intermediate signal being in phase with an input signal varying between the first logical value and the second logical value, and an antiphase intermediate signal antiphase to the input signal. The generator also includes a first connecting means for simultaneously transferring the second logical value of the positive-phase intermediate signal and the first logical value of the antiphase intermediate signal to a positive-phase signal output part and an antiphase signal output part in synchronism with a state change of the input signal from the first logical value to the second logical value.

A ring configuring method configures a network in which a plurality of nodes are connected linearly, and performs topology construction for the ring by circulating topology data through the respective nodes and collecting connection information of the respective nodes. The method includes the steps of providing in the topology data a flag indicating whether the connection information is collected in each node; inverting the flag at a terminal station which is an end node of the open ring, and turning the topology data there; causing the topology data to passing through a node other than any terminal station as it is; and adding the connection information to the topology data in each node according to the flag, and performing topology construction.

A delay circuit includes an output circuit including first and second output elements. The first and second output elements are connected serially between a first power supply source and a second power supply source. The delay circuit further includes a delay element, which is coupled between a first input circuit and an output circuit to generate a first control signal that is delayed with respect to the input signal. The delay circuit still further includes a first node coupled between the delay element and one of the first and second output elements; and a second node, coupled to the other output elements to supply a second control signal having substantially no delay with respect to the input signal.

A magnetic head apparatus including a magnetic head slider having at least one thin film magnetic head element, a suspension mounting the magnetic head slider on one face thereof, an IC chip mounted with a circuit for the thin film magnetic head element and a support arm fixedly supporting the suspension in which the IC chip is mounted on the one face of the suspension and is thermally coupled to the support arm.
摘要:
An input circuit is established between an input pad and a first stage input gate; a determining portion and switching portion are established in this input circuit. The determining portion determines the presence of bonding to an input pad according to the potential of the input pad. The switching portion outputs a low level signal to the first stage input gate when the determining portion determines that “there is no bonding” and connects the first stage input gate with the input pad when the determining portion determines that “there is bonding”.

A lighting apparatus which enables a shade to be easily attached, detached and rotated with a simple structure and an enhanced degree of freedom in design. Grooves 9,10 defining arc-shaped portions 15,16, respectively, are formed around an axis of a head 4, to which is mounted a fluorescent light bulb 7. A shade 8 which is formed with protrusions 17, 18 opposite to the grooves 9, 10 is mounted to the head 4 so as to cover the fluorescent light bulb 7. By pressing the protrusions 17, 18 of the shade 8 into the grooves 9, 10 of the head 4, the shade 8 can be very easily mounted to the head 4. By lifting up the shade 8 from the head 4, the shade 8 can be very easily removed from the head 4. In addition, the shade 8 can be rotated by allowing the protrusions 17, 18 formed on the shade 8 to slide along the arc-shaped portions 15, 16. As such shade 8 allows a simple integral structure, degree of freedom in designing a lighting apparatus can be enhanced.
