Title: Logic circuit
Inventor: MIYAZAKI MASAHIDE
IPC: G01R31/28
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To make changeable a serial access system and a parallel access system only by only changing an addition circuit outside an IP core regarding the bidirectional three-state output terminal of the IP core and to minimize the number of addition circuits by providing a signal propagation route by which a bidirectional-mode changeover-signal internal terminal is connected to a bidirectional-mode changeover-signal external terminal. SOLUTION: In ordinary operation, an element 350 outputs a signal which controls the signal value of the mode changeover-signal internal terminal 322 of a lower-layer logic circuit 320 with reference to three-state elements 354, 352. Thereby, a bidirectional data external terminal 152 and a three-state output terminal 156 function normally according to the logic level of the mode changeover-signal terminal terminal 322. Then, in a test operation, the element 350 is fixed to a level 'LOW' irrespective of the logic level of the mode changeover-signal internal terminal 322, and the three-state elements 354, 352 are set to a high-impedance state. Thereby, it is possible to prevent a fear that a through current due to a bus conflict during the test operation is generated.

IPC: G11B15/467
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To intensify the reading capability of a read head of a magnetic tape data storage device. SOLUTION: This method for the data storage device which may be constituted to write and read the stream of data as a series of tracks in a direction crossing the main length of a data memory medium minimizes the difference between the route that the read head of the data storage device follows up and the route that the plural tracks written on the data memory medium follows up. The method described above reads the plural data block fragments constituting at least one among the written tracks from the data memory medium (1401), stores the respective positions of the plural fragments existing within the tracks of the read data into the memory device (1402), and stores the time for reading the respective fragments of the plural fragments of the read data (1402).  In succession, calculates the differences between the positions of the read fragments on the data memory medium and the corresponding ideal positions (1404, 1405, 1406, 1407 and 1408) and corrects the route that the read head of the data storage device follows up by using these differences.

Title: Bending operation device
Inventor: TAKEHATA SAKAE
IPC: G02B23/24
Filed: 1989-08-31
Abstract: PURPOSE:To always maintain the bending quantity of a tubular insertion tool at the optimum state regardless of the injection of liquid by detecting the injection of fluid to the tubular insertion tool, and controlling energizing with the output. CONSTITUTION:When physiological saline solution is injected with a syringe 5, the physiological saline solution flows from a physiological saline solution injection tube 1a to a treatment tool insertion hole 14, and flows out from a treatment tool projecting port 3. When the physiological saline solution is injected, the detection pressure P of a pressure sensor 10 is increased. At this time, an injection detecting signal is supplied from a pressure detecting part 14 to a control part 11 when the detection pressure P exceeds a preset value  P. The control part 11, in the case of receiving the injection detecting signal, reduces the cycle of a driving voltage pulse in a driving circuit 13 less than that at the present time by a prescribed value. When the cycle of the driving voltage pulse is reduced, an energizing quantity supplied to a wire 6a or 6b is increased. The temperature of the wire 6a or 6b intends to decrease transiently when the physiological saline solution is injected. However, the lowering of the temperature can be compensated with the increment of the energizing quantity. Thereby, the bending quantity theta of a catheter 1 can be kept constant regardless of the injection of the physiological saline solution.

Title: Solid-state image pickup device and signal processing method of the same
Inventor: NAKAMURA SATOYUKI
IPC: H04N5/335
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To normally signal-process output from a LOG sensor even if a circuit of a post stage, which executes various signal processings, is left to be the circuit processing a signal which is linearly converted in a solid-state image pickup device where the LOG sensor of a wide dynamic range (area sensor where photoelectric current is logarithm-converted) is installed as the area sensor. SOLUTION: The output of an electric signal which is logarithm-converted by an area sensor 1 is converted so that it becomes the electric signal which is linearly converted with respect to incident light by a conversion circuit 3 by using a calculation expression by which inverse logarithm conversion stored in a memory 2 is executed. The output is converted and is transmitted to a processing circuit 4. Thus, the electric signal outputted from the area sensor 1 can be signal-processed in the processing circuit 4 processing the existed signal which is linearly converted even if the area sensor 1 is set to be the LOG sensor.
