Title: Operating magnetic fluid
Inventor: EGUCHI KIYOSHI
IPC: C10N40/14
Filed: 1988-03-14
Abstract: PURPOSE:To prevent magnetic fluid for changing passages in branch pipes from reacting with reactive fluid, being oxidized and evaporating, by wrapping the magnetic fluid with a membrane made of soft and breakage-resistant materials. CONSTITUTION:A magnetic fluid 10 is charged in a branch pipe so as to perform valve action is wrapped by a spherical chloroprene membrane 11 which is soft and breakage-resistant. When the magnetic fluid 10 wrapped with the membrane 11 is led into a suitable recess in the branch pipe with the use of a magnet moved along the branch pipe, it is possible to change flow passages. When the fluid is displaced, the movement of the magnetic fluid along the passage may be facilitated since the membrane 11 is soft so that it can change its shape in conformity with the shape of the passage to allow smooth movement. This magnetic fluid 10 is errosion-resistant against the other fluid or the like, having a sufficient gas-tight ability, thereby there is no possibility of other fluid or air-bubbles passing therethrough.

Title: Radar transponder
Inventor: KAWAKAMI YOICHI
IPC: G01S13/76
Filed: 1987-03-16
Abstract: PURPOSE:To receive a searching radar signal, by providing a video switch (SW) opening and closing by the output signal of a control circuit between a video amplifier and a video auxiliary amplifier to return the same to a normal operation state immediately after the stoppage of transmission. CONSTITUTION:A received searching radar signal is sent to an FET amplifier 2 and a detector 3 and the detection output of said detector 3 is amplified to a level necessary for triggering a control circuit 6 by a video auxiliary amplifier 5 through a video amplifier 4 and SW 12. The circuit 6 triggered by said amplified output outputs a positive voltage pulse signal to SW 12. During a transmission period, a positive voltage pulse becomes an H-level not only to bring SW 12 to a closed state but also to cut off the output of the amplifier 4. Other than the transmission period, a positive voltage level becomes low to bring SW 12 to an open state and the output of the amplifier 4 is inputted to the amplifier 5. Since SW 12 is brought to a closed state during transmission period to prevent an input signal of an H-level from being applied to the amplifier 5, the searching signal can be received immediately after the stoppage of transmission.

Title: Terminal fitting of fluid transport tube
Inventor: UMEHARA MITSUO
IPC: F16L33/28
Filed: 1992-02-14
Abstract: PURPOSE:To shorten the time required for mounting, and to reduce the cost by bending the end part of an external reinforcing member into the letter V, and by sandwiching the end part in two direction, namely, between an inner ring and a front press fitting, and between the inner ring and a rear press fitting. CONSTITUTION:The end part of an external reinforcing member 17 is bent into the letter V, and is sandwiched between a front tapered surface 53a of an inner ring 53 and a front press fitting 55A, and between a rear tapered surface 53b of the inner ring 53 and a rear press fitting 55B, receiving gripping force in two directions. Strong anchoring force thus works on the load in the axial direction, and no welding is required. Since the end part of the external reinforcing member 17 can only be bent into the letter V, bending molding is facilitated compared with the case in which the end part is folded back. Mounting work of the terminal fitting to a liquid transport tube 11 is thus facilitated, and the time required for mounting can be shortened, while the cost can be reduced.

Title: Image recorder
Inventor: NONOMURA HIROSAKU
IPC: G03B27/50
Filed: 1987-03-13
Abstract: PURPOSE:To increase the size of the areas of individual picture element electrodes and to decrease the uneven colors and uneven streaks of recorded images by converting the luminous flux transmitted through a liquid crystal shutter array consisting of a liquid crystal cell having a rectangular or elliptic electrode pattern to a square luminous flux and guiding the same to a photosensitive material. CONSTITUTION:The pattern of the picture element electrodes 4 of the liquid crystal shutter array 2 is rectangular. The size of the short side 4a thereof is nearly the same as the size of one side of the conventional picture element electrodes and the size of the long side 4b is several - some ten times the size of one side of the conventional picture element electrodes. Lenses 13, 13' in this case are of a semicircular shape and converge light in an X-axis direction but not in a Y-axis direction. The luminous flux emitted from the lens 13', therefore, converges in the X-axis direction and does not converge in the Y-axis direction of the rectangular shape if the liquid crystal shutter 2 and the lens 13' are so disposed as to bring the direction of the long side of the luminous flux transmitted through the electrodes 4 to the direction of the X-axis. The picture element information of the square shape is consequently recorded on the photosensitive material 3. The 'uneven colors' and 'uneven streaks' of the recorded images are thereby decreased.

IPC: H04B3/04
Filed: 1983-04-05
Abstract: PURPOSE:To relieve the restriction of a transmission speed and to reduce the waveform distortion of a signal by controlling level variation in the output voltage of a main amplifier within the range of the amplitude of a steady error output voltage between both output voltages of a peak detecting circuit and a mean value detecting circuit. CONSTITUTION:The output voltage ep of a peak detecting transistor (TR) 3 including the steady error output voltage and the mean value detection output voltage ea of a mean value detecting TR4 are inputted to an operational amplifier 2. Then, the gain of the main amplifier 1 is controlled to hold the level variation in the voltage amplitude of an output data signal within the range of the steady error output voltage of the TRs 3 and 4. Consequently, the time constant of a negative feedback loop is increased, so the restriction of the data transmission speed is relieved to perform high-speed data communication; and the output level is stabilized without any influence of the DC level variation of the input signal and the loop gain of negative feedback is increased, so the waveform distortion of the output data signal is reduced.
