Title: Blade control type towing body
Inventor: EMORI ICHIROU
IPC: B63G8/42
Filed: 1979-03-14
Abstract: PURPOSE: To ascend or descend a towing body to maintain a fixed height thereof automatically by a method wherein an attack angle of a blade is varied by means of the link mechanism actuated by the water bottom detecting leg.  
     CONSTITUTION: When the sea bottom E of towing direction is going up, the height from the sea bottom surface E becomes short, in this case the blade 2 being inclined to B' side to develop the angle of attack by pushing the leg 4, allowing the towing body 1 to go up by increasing the resistance force by water current. On the contrary, when the sea bottom E of towing direction is going down, the attack angle of the blade 2 becomes a depression angle, allowing the towing body 1 to go down by increasing the water current resistance force.

Title: Metal multiple oxide powder and its production
Inventor: TAMURA MINORU
IPC: C01B33/18
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain fine irregular metal multiple oxide of high purity with little metal contamination by hydrolyzing and condensing a mixture of silicon alkoxide and specified metal alkoxide to obtain a gel, then pulverizing and burning the gel. SOLUTION: Water is added by 0.1 to 2.0mol to silicon alkoxide in the presence of an acid catalyst to induce partial hydrolysis and condensation to obtain a silicon alkoxide low condensate. The obtd. low condensate is mixed with an alkoxide of group IV metals in the periodical table except for silicon, or with a mixture of an alkoxide of these metals and an alkoxide of group I to III metals in the periodical table by 100:0 to 40:60 molar ratio, and the molar ratio of the mixture of the condensate and the alkoxide is 99:1 to 50:50. Then water is added by 2 to 100mol to one mole of the alkoxide to hydrolyze and condensate at -10 to 80 deg.C in the presence of an acid catalyst to obtain a gel. The gel is dried, pulverized and burned at 400 to 1400 deg.C to obtain an irregular metal oxide powder having <=10μm average particle size and <=200ppm sum content of Fe, Cr and Ni.

Title: Ultrasonic sensor for measuring distance
Inventor: USUI KATSUYA
IPC: G01S7/527
Filed: 1987-02-10
Abstract: PURPOSE:To measure distance accurately in a wide distance measuring range from a short to long range, by automatically setting a threshold according to changes in the intensity of reflection of an ultrasonic wave. CONSTITUTION:An ultrasonic sensor S3 transmits an ultrasonic wave to the ground at a set cycle from a transmitter 4a based on a command P0 of a threshold control means 101 and the reflected ultrasonic wave thereof is received with a receiver 4b to output a reception signal P1 to a reception detecting means with the level corresponding to the intensity of the reflected ultrasonic wave. The reception detecting means composed of a comparator 27 and an FF 28 detects the level of the signal P1 and outputs an interrupt signal P3 to the means 101. When the reception detecting means does not detect the reception of the reflected ultrasonic wave, a set threshold is brought down to a lower value by one order of magnitude than the current set value by a threshold altering means 29 based on the command of the means 101. Thus, even when the intensity of the reflected wave lowers, the timing of receiving the reflected wave can be detected accurately. With the reception of the reflected wave, the threshold once lowered is raised by one order of magnitude to suppress malfunctioning of the reception detecting means due to excessive lowering of the threshold thereby enabling accurate measurement of distance in a wide distance measuring range.

Filed: 1983-02-24
Abstract: PURPOSE:To prevent degradation of the engine performance at the time when operation of a sensor for detecting the quantity of intake air becomes abnormal, by setting the basic injection quantity of fuel at a prescribed value corresponding to the engine speed when operation of the above sensor becomes abnormal in a control apparatus in which the basic injection quantity of fuel is calculated from the quantity of intake air and the engine speed. CONSTITUTION:In operation of an engine, a signal representing the quantity Q of intake air detected by an air-flow meter 11 and a signal representing the engine seed N detected by a crank-angle sensor 13 are picked up from an input circuit 12 to a judging circuit 14 at predetermined time intervals. In the judging circuit 14, the quantity Q of intake air is compared with a reference value Q0. In case of Q>Q0, the air-flow meter 11 is judged to be normal. In case of Q<Q0, on the other hand, it is judged to be abnormal. Here, if the air-flow meter 11 is judged to abnormal, comparison is made between ''fuel cut'' engine speed Nc and the actual engine speed N in an auxiliary arithmetic circuit 16, and in case of N>Nc, ''fuel cut'' is effected. On the other hand, in case of Nc> N>No (No is the cranking speed), the final injection quantity of fuel is determined by furnishing a prescribed basic injection quantity Tpo to an arithmetic circut 15 and correcting the injection quantity Tpo appropriately.
