Title: Revetment work
Inventor: NISHINO HIROSHI
IPC: E02B3/12
Filed: 1985-08-05
Abstract: PURPOSE:To protect sea-eroded cliff from the eroding action of ocean current while keeping its landscape by a method in which coarse sand having good fixability is charged in the front of sea-eroded cliff to form an artificial beach. CONSTITUTION:Coarse sand of Takahagi-bed sandy rock group is charged in the front of a sea-eroded cliff 1 up to the upper height of a waves-eroded cavity 2 to form an artificial beach 5 between the cavity 3 and the surrounding to the reef 4. The sea surface of the coastal area can thus be calmed down, the force of reflecting waves is weakened, and the sand of the offing is deposited on the artificial beach 5. The eroding action of ocean current to the sea-eroded cliff 1 can be lowered without damaging the landscape.

Title: Amplifying circuit
Inventor: TAKEYASU KENJI
IPC: H03G3/12
Filed: 1984-08-17
Abstract: PURPOSE:To decrease the number of components and to eliminate variation of a DC component in the input of a muting signal by connecting means which receives the muting signal and performs switching operation in parallel to a feedback resistance connected between input and output terminals of an amplifying means. CONSTITUTION:When no muting signal is inputted to an input terminal 8 and a signal is inputted to an input terminal 1 while the switching means is off, this signal is amplified by -R2/R1 (R1 and R2: resistance values of input resistance 3 and feedback resistance 4) times through the amplifying means 2 and outputted to a terminal 7. On the other hand, when the muting signal is inputted to the terminal 8 and the means 5 is on, the output terminal and inverted input terminal of the means 2 are short-circuited, so the voltage of the means 2 is 0 time; even if a signal is inputted to the terminal 1, it does not appears at a terminal 7. Therefore, variation of the DC component in the input of the muting signal is eliminated.

Filed: 1980-12-08
Abstract: PURPOSE:To effectively stabilize the variance in horizontal amplitude of a screen, by detecting the anode current of a cathode ray tube and superimposing it on a reference voltage of a power supply circuit of switching regulator type or a detected voltage. CONSTITUTION:When an anode current of a cathode ray tube of a television set is increased, the anode voltage is lowered and horizontal amplitude of screen is increased and a minus AML voltage is greatly generated at a point (c). This voltage is divided at resistors R10, R9 and applied to one end of a constant voltage diode D1, allowing to add it to a part of the reference voltage of a point (b). Thus, a switching control circuit Q changes a conducting period of a transistor TR2 and lowers an output voltage of a point (d).

Abstract: PURPOSE:To completely shield the rays of light with slight movement of an shielding piece, by shielding the rays of light by inserting the shielding piece between a rod lens and optical fiber. CONSTITUTION:When optical fibers 11a and 11b are respectively inserted into precise sleeves 12a and 12b which have the same diameter as a rod lens 13 has and the sleeves 12a and 12b are put in a V-groove 14, the optical axis of the fibers 11a and 11b are automatically aligned with each other. Therefore, when the focal distances of the lens 13 and fibers 11a and 11b are adjusted, they can be coupled optically.
