Title: Oil tank structure in tanker
Inventor: KONDO KIMIO
IPC: B63B3/00
Filed: 1993-04-05
Abstract: PURPOSE:To facilitate the installation of a bellmouth and the maintenance of an oil tank structure by forming an oil sucking recess on the bottom surface of an inner plate even without providing a reinforcing longitudinal material on the bottom surface of the inner plate. CONSTITUTION:Oil 10 stored in an oil tank 4 is sucked by a bellmouth 9 to start the oil transfer to the outside of a tanker hull 1. As the oil 10 is successively reduced, the oil 10 flows toward an oil sucking recess 8 along an inclined bottom surface 3A of an inner plate 3 so that almost all the oil 10 stored in the oil tank 4 is transferred to the outside of the tanker hull 1 through the bellmouth 9.

IPC: H01M12/08
Filed: 1982-05-11
Abstract: PURPOSE:To eliminate camber, distorsion, etc. by lowering the apparent linear expansion factor of an electrode and electrode material. CONSTITUTION:Rectangular inside frame 60a having predetermined thickness, glasswool sheet 12 and an outside frame 60b serving as a frame for a microchannel 5a are laminated sequentially to produce a framed electrode 50. The thickness of the electrode 70, inside frame 60a, outside frame 60b and glasswool 12 are set respectively to 1, 0.3, 1, 1. In this case the total thickness of the inside frame 60a and outside frame 60b is 1.3, preferably 1.3-1.4. When it is thinner than 1.2, the absolute volume of the inside frame 60a is insufficient to produce defective mold due to insufficient filling of frame at the detail of metal die, while when it exceeds over 1.5-1.6 the volume of frame will be excessive to produce ripple on the surface of the electrode 70 or to produce a portion where the metal die electrode surface is not transferred completely.

IPC: H04N1/41
Filed: 1981-05-22
Abstract: PURPOSE:To decrease the time of transmission and to reduce the capacity of storage, by separating a half-tone picture signal of N gradation to a binary signal and an N/2 gradation signal and then coding the binary signal and the N/2 gradation signal by a binary facsimile signal coding system and by the difference of gradation to the contiguous picture element, respectively. CONSTITUTION:A half-tone picture signal of N gradation which is stored in a half-tone picture signal memory 1 is binary-coded and stored in a binary coded signal memory 3. For this binary coded signal, the changing point and the duration of the code are discriminated by a changing point detecting circuit 4 and a state mode discriminating circuit 5 to be stored in a binary coded data memory 8. On the other hand, the N gradation signal in the memory 1 is converted into an N/2 gradation 9 to obtain a difference to the contiguous N/2 gradation signal. This difference is stored at 11. A difference signal discriminating circuit 12 decides whether or not the gradation difference signals are all ''0'' in terms of the block of the memory 11. The result of this decision is stored in a gradation difference code data memory 15. Then the coded binary signal in the memory 8 and the coded gradation difference signal in the memory 15 are delivered alternately.

Title: Extracting device of marker signal
Inventor: TOKUNAGA SHIGEKI
IPC: G01S7/285
Filed: 1988-03-30
Abstract: PURPOSE:To enable the stable detection of a marker pulse signal in a reproduced state, by converting a stem marker into a stem marker pulse signal having a specified pulse width and being continuous by the specified number of pulses. CONSTITUTION:A stem marker Ma indicating the direction of operation, i.e. the direction of advance, of a moving body such as a ship is inputted to a pulse train generating circuit 1 and converted therein into a pulse train, which is mixed with a radar video signal Vi in a mixing circuit 2. The mixed signal turns to be as shown in the figure, and therefore it is unnecessary to give any special level discrimination thereto. Consequently, recording and reproduction thereof in a recording-reproducing element 3 of a determined dynamic range can be implemented easily. Since the mixed marker pulse signal Ma2 is determined in respect to a pulse width and the number of repetition beforehand, a reproduced marker RMa can be obtained only when the pulse train Ma2 arrives.

Title: Ultrasonic parametric speaker
Inventor: KOBAYASHI SUSUMU
IPC: H04R1/40
Filed: 1990-03-27
Abstract: PURPOSE:To prevent a side lobe from being generated from an ultrasonic wave (primary wave) radiated from plural ultrasonic wave vibrators and to improve the directivity by arranging lots of the ultrasonic wave vibrators in the middle and a few vibrators toward the circumference so that the sound pressure distribution of the ultrasonic wave is made close to the Gauss distribution. CONSTITUTION:Plural ultrasonic wave vibrators 1 are not arranged uniformly to a ultrasonic wave vibrator fixed member 2 as seen in a conventional system but many ultrasonic wave vibrators are arranged in the middle and less toward the circumference. In more details, the ultrasonic wave (primary wave) radiated from the plural ultrasonic wave vibrators 1 causes a sound pressure distribution close to the Gaussian distribution (so-called normal distribution) G in which side lobe is theoretically zero through the arrangement of the ultrasonic wave vibrators 1 at a narrow interval in the middle of the ultrasonic wave vibrator fixed member 2, that is, a dense state, and at a wider interval toward the circumference gradually, that is, a thin state. Through the configuration above, the production of a side lobe from the primary wave is prevented to improve the directivity, and then the directivity of the secondary wave caused from the primary wave is improved.

Title: Plasma vacuum device
Inventor: NAKAGAWA YOSHIYUKI
IPC: H01L21/205
Filed: 1988-04-01
Abstract: PURPOSE:To prevent any scattering materials from bonding onto the surface of an anode thereby enabling plasma to be formed in a constantly stable state by a method wherein the pressure near the anode opposite to a hollow anode type plasma beam source is made higher than the pressure in a vacuum vessel. CONSTITUTION:Atoms and molecules permeating from a vacuum vessel 10 into an anode 30 are extremely decreased by an electron beam passing port 36 in small diameter of an anode focuccing coil 35. The electrons in plasma focussed by the magnetic field of the coil 35 past through the passing port 36 to reach an anode plate 32. The part near the anode 30 is pressurized higher than the vacuum vessel 10 due to the gas led in from a gas leading-in port 34. The gas runs from the anode 30 to the vacuum vessel 10 to collide against the permeating atoms and molecules for interrupting the permeation thereof. Even if the atoms and molecules contaminating the anode plate 32 permeate into the anode 30, the mean free strokes thereof are shortened by the higher pressure in the anode 30 to make them hardly bond onto the anode plate 32. Through these procedures, plasma may be enabled to be formed in the constantly stable state.
