Title: Floating head for magnetic disk
Inventor: NAKAYAMA MASAO
IPC: G11B5/60
Filed: 1986-05-29
Abstract: PURPOSE:To attain high sensitive detection for the presence/absence of contact between a head and a disk, by connecting a shock sensor in which electrodes are formed on both planes of a piezoelectric plate, to a magnetic head core on one end face of the sensor, and sandwiching and making them in one body with a non-magnetic slider member from both planes. CONSTITUTION:A floating head 20 is structured in such a way that a shock sensor 26 in which electrodes 24 are formed on both planes of a piezoelectric plane 22, is connected to a ring type magnetic head core 28 on one end face of the sensor, and they are sandwiched and made in one body with non-magnetic slider members 30 and 32 from both planes. A piezoelectric ceramics is used for the piezoelectric plate 22, and the electrodes 24 are formed at the lower part of both planes of the plane, thereby, constituting the shock sensor 26. A magnetic head core is formed by joining two C-type cores oppositely. and a recording/reproducing gap 34 is formed at the joined plane. If the head 20 is brought into contact with the disk, an electric charge is generated at the piezoelectric plate by shock vibration generated at the time of the content, and a voltage is induced between both electrodes, thereby, it is possible to detect the presence/absence of the contact by a voltage signal between both electrodes.

Similarly, the input voltage is sequentially changed and the error in the upper rank 4-bit of the converter 11 is all memorized 21. Next, the memory 21 is read out and it is converted into readout mode, allowing to each corrective output according to the outputs 3-1 to 3-4. This is added 72 to the outputs 3-1 to 3-4 and accurate output 8 can obtained

IPC: G06F13/00
Filed: 1981-08-08
Abstract: PURPOSE:To enable correction of reading error by a pseudo input/output device and facilitate testing, by using an IC in place of a reading medium of an input/ output device and performing correction of errors when the frequency of occurrence of errors attains a required frequency. CONSTITUTION:A pseudo input/output device consisting of an IC memory 2 that is substitutive for the reading medium of an input/output device 1 and a controlling section 3 is connected to a channel device CHC or an input/output controlling device IOC.

Title: Communication equipment
Inventor: ASO TAKASHI
IPC: H04J3/16
Filed: 1996-05-20
Abstract: PURPOSE: To make data multiplex transmission efficient by changing the code compression method for each data block of a short time by the voice input signal characteristic. CONSTITUTION: A data amount comparator section 10 measures a digital data amount generated from A/D converters 5, 8 to obtain its ratio. A code compression method decision section 11 decides a compression method of voice and image data as a processing result of a sound processing section 4 and information being an output of the comparator section 10 for each period of a synchronizing signal time of a synchronization generating section 14. That is, when a voice input indicates silence and high quality transmission is not required, the compression rate is increased to reduce the transmission data quantity to increase image transmission data quantity. Furthermore, when high quality transmission requiring rapid fluctuation in voice data is requested, the compression rate is decreased to compress data in a form reproduced tightly.  Since the image data transmission capacity is reduced in this case, a data reception speed by an image input section 7 and a conversion section 8 is reduced. Then a data synthesis section 12 synthesizes data from voice and image data compression sections 6, 9 based on a synchronizing signal outputted from the synchronizing signal generator 14 to provide an output of the result via a modulation section 13.

Title: Method and apparatus for diagnosis of corrosion-proof coating damaged part in buried pipe
Inventor: AMANO YOSUKE
IPC: G01N27/83
Filed: 1995-05-24
Abstract: PURPOSE: To judge and diagnose a corrosion-proof coating damaged part easily and quickly by a method wherein an AC signal is made to flow to a corrosion-proof coated buried metal pipe and zero points of signals in which a positive polarity and a negative polarity have been added to rectified values due to the rectified output of a detected ground surface potential difference and due to the phase relationship between the ground surface potential difference and a magnetic detector are set in the same position. CONSTITUTION: Magnetism VS which is generated by an AC signal current 110 flowing in a metal pipe 10 is detected 130 by a detector 19, and a potential VB, on the surface of the ground, which is generated by a signal current 111 flowing in the ground is detected 120 by wheel electrodes 17, 18. Then, when a receiving device 16 advances to a corrosion-proof coating damaged part 14, the polarity of the magnentism VS by the signal current and the polarity of the potential VB in the ground are set to a reverse correlation. However, after a receiving device 16A has passed the damaged part 14, both polarities are set to a normal correlation. When they are in the reverse correlation, the potential VB is output as a negative signal, and, when they are in the normal correlation, the potential is output as a positive signal.  The zero point of a waveform which has full-wave-rectified the potential VB and that of signal waves to which a positive polarity and a negative polarity have been added are set in the same position so as to be output. Then, the damaged part 14 can be read easily.

The mixed flow of air and water from a space 1' passes rapidly through the sponge filter layer 2 at high speed to press the sponge filter layer 2 so that captured turbid matter is squeezed out. Then the mixed flow is discharged to the outside through a wash water discharge pipe 10 and the rapid opening valve 9.
