Title: Receiver of measuring device for shell speed
Inventor: MIYAZAWA FUMIO
IPC: G01S13/58
Filed: 1984-02-15
Abstract: PURPOSE:To narrow down passing band width, improve radar performance, and manage with one band-pass filter and simplify the constitution by making the passing frequency of the band-pass filter coincident with the frequency of a Doppler signal automatically. CONSTITUTION:The Doppler signal amplified by a video amplifier 1 is distributed by a distributor 10 as an input signal fd1 to the frequency control type variable band-pass filter 13 and an input signal fd2 to a frequency discriminator 11. The discriminator 11 converts the frequency of the signal fd2 into a voltage, which is supplied to a voltage-controlled oscillator 12. The filter 13 is brought under switching control with the output signal fCNT of the oscillator 12, whose sensitivity is so adjusted that the detection frequency of the discriminator 11 coincides with the passing frequency of the filter 13; and the Doppler signal fd1 of the distributor 10 is passed through the filter 13, amplified by the video amplifier 9, and sent out to a signal processor.

Title: Flexible tube for endoscope
Inventor: HOSAKA KIYOKAZU
IPC: G02B23/24
Filed: 1983-02-21
Abstract: PURPOSE:To obtain a flexible tube for endoscope that does not crease on its outer cover by bending and does not lose flexibility by interposing a porous tube made of a specified material between the flex and braid. CONSTITUTION:In the flexible tube 5 of an endoscope 1, as a porous tube 18 made of polytetrafluoroethylene interposed between the flex 14 and braid 15 has a very small friction coefficient, the flex and braid 15 can move freely to each other. Accordingly, when the flexible tube 5 is bent, the flex 14 contracts the inside of bent of the flexible tube 5, and the pitch between plates becomes small. Howver, the braid 15 absorbs the change of distance by its whole length of inside of bending. Consequently, no excessive force is applied on the braid 15, and no contraction and swelling is caused. Thus, no crease is formed on the outer cover 16. The flex 14 is elongated on the outside of bending and the pitch of plates is enlarged. However, as the change is compensated by the whole length of the braid 15, elongation of the flex is not suppressed, and the flexible tube 5 can be bent freely and easily and largely.

Filed: 1980-03-05
Abstract: PURPOSE:To maintain the intensity of a laser beam at a fixed level by monitoring a laser beam from one optional facet of a plural number of facets of a polygon mirror for laser beam scan and controlling the intensity of a laser output light. CONSTITUTION:In accordance with an output from a sample hold circuit 8, a laser diode drive current is changed and a polygon mirror 3 is controlled through its correction once for every revolution so that the intensity of a laser beam on a photosensitive plate may stay at the same level. In addition, a laser diode is again put in ''ON'' position so as to obtain a horizontal synchronous signal. The first laser drive current is set at a reference set value and after this setting, a laser power is detected with the assistance of a beam detector once for every revolution of a polygon mirror. Following this process, a laser drive current is corrected moment by moment every time a sample is held by a sampling circuit in such manner that the said current may always be at a fixed level on the photosensitive element 1.

Filed: 1980-03-05
Abstract: PURPOSE:To automatically compensate for by operating and estimating an approximate electric energy which would otherwise be obtained by a faulty measuring instrument, even when part or the entirety of the measuring instrument is faulty temporarily. CONSTITUTION:An output from an integrating wattmeter W1, W2 is converted to a digital value by means of an external counter C1, C2 and then is input to a computer system 10. An output from an integrating wattmeter W2-W7 of a feeder is input to the computer system 10 as a pulse signal. For instance, when the wattmeter W1, W2 is faulty or is turned around for maintenance past electric energy data regarding the wattmeter W1, W2 which is memorized by an auxiliary memory unit 11 is input to the computer system 10. As a result, the electric energy during the faulty or maintenance period is operated and estimated to provide an estimated value. Under this constitution, it is possible to compensate automatically for an electric energy close to the electric energy which would otherwise be obtained by means of a faulty measuring instrument, etc.

Title: Fluid bearing type rotary magnetic head device
Inventor: INAMI TOMOTAKE
IPC: G11B5/52
Filed: 1989-02-07
Abstract: PURPOSE:To prevent a bearing from being damaged in the course of recording and reproduction by incorporating a device for detecting a service life of a fluid bearing. CONSTITUTION:When a radial bearing 9 is rotated, a thrust bearing 4 floats up a little, and also, the radial bearing 9 and the center axis 3 hold an appropriate gap, the axis 3 and the bearing 4 do not come into contact directly to each other and a fixed cylinder 5 is rotated. A head 6 attached to the cylinder 5 also rotates and information is recorded and reproduced to and from a magnetic tape. When a voltage is applied between a brush 12 and the center axis 3 is such a normal state and a contact resistance is measured, it becomes large. However, when a bearing 11 reaches its service life or evaporates and its quantity decreases, pressure of bearing grease 11 of a thrust bearing part and a radial bearing part is eliminated and the bearing 4 and the bearing 9 come into contact with the axis 3. In such a way, by detecting a fact that an electric resistance becomes small and outputting an electric signal, a recording/ reproducing device is stopped and an alarm is issued to the outside.
