Abstract: PURPOSE: To improve the access speed of the recording medium reproducing device which reads data out of a recording medium and reproduces them. CONSTITUTION: A head data storage memory 39 for storing head data of respective data files recorded on an optical disk 22 is prepared and the head data of the respective files are stored in this memory 39 by N blocks in a period other than a reproducing operation period corresponding to a data read request. When a request to read data out of a file on an external device is generated, the data begin to be read from a K(2<=K<=<=N+1)th block from the head of the file on the disk and are transferred to the external device after reading data of the file from the head out of the memory 39.  The data read out of the disk are processed as specified and stored in a buffer memory 32 and then when they become able to be read out of the memory 32, the read of data from the memory 39 is quit at a (K-1)th block and data begin to be read out of the memory 32 and are transferred to the external device.

Abstract: PURPOSE:To always stably print an image having a satisfactory high resolution on paper by opposing segment electrodes and a spiral electrode through a toner conveyor, feeding a recording material to an electrode opposing part, and interposing an insulator between signal electrodes. CONSTITUTION:When a screw pole 4b is rotated in a direction of an arrow (b), a linear electrode 4g is moved in parallel from left to right.

IPC: G01L19/14
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To suppress the flow-out of, for example, a gas to a specific safe range during measurement even if an airtight part is damaged by providing a flow-rate-limiting part for narrowing the space of a fluid-introducing port at one portion in the fluid-introducing port. SOLUTION: A cylindrical fluid-introducing port 20 that projects downward is provided at the center of the bottom surface of a lower housing 18 of a pressure sensor and a projecting flow-rate-limiting part 22 is formed around the inner wall surface of the peripheral surface. Then, the diameter is set to, for example, approximately 0.3-0.5mm. Then, by introducing a gas to be measured through the limiting part 22 from the introducing part 20, the limitation in the flow rate does not cause any problem for pressure measurement since the pressure of the gas to be measured may be transferred for normal measurement.  Then, even in the case of the break of the airtightness of an O-ring, and the peeling-off of the adhesion surface, the flow rate of the gas to be measured that flows out is limited to a specific, safe range by the limiting part 22, thus preventing a large amount of flow-out toward the outside.

Abstract: PURPOSE:To prevent the occurrence of crosstalk between input and output signal lines by adopting the constitution such that the lower end face of a gate type vertical plate is bonded closely to a metallic base while its opening bridges over a semiconductor chip so as to fix a shield body to the metallic base. CONSTITUTION:The space of the semiconductor device is separated into, the side of all input signal line 3 and the side of an output signal line 4 by a shield body grounded to the metallic base 10.
