Title: Manufacture of flake graphite
Inventor: SUETSUGU YOSHIO
IPC: C01B31/04
Filed: 1980-06-16
Abstract: PURPOSE: To efficiently manufacture high purity flake graphite by repeating a process of heat carbonizing a fixed amount of an iron group metal in a nonoxidizing atmosphere and a process of depositing flake graphite by cooling and collecting it.  
     CONSTITUTION: Carbon such as pitch coke is added to a molten iron group metal, especially molten cast iron held in a nonoxidizing atmosphere, and by heating to ≥1,400, especially ≥1,450°C the molten metal is satd. with carbon. The satd. molten cast iron is cooled to ≤1,300, especially ≤1,250°C by blowing a nonoxidizing gas such as N 2  to deposit flake graphite. The graphite is introduced into a cyclone or the like together with exhaust gas, and it is collected. Carbon is added to the molten cast iron again after collecting the flake graphite, and the iron is satd. with carbon at said temp. It is then cooled by similar operation, and deposited flake graphite is collected. By repeating said operation using the same molten cast iron, flake graphite is collected and recovered.

Title: Reducing method of amount of sludge produced in pickling of iron and steel
Inventor: TSUNODA HARUHIKO
IPC: C23G1/00
Filed: 1978-07-01
Abstract: PURPOSE: To reduce the amount of sludge produced and make handling of waste easy by oxidizing the sludge produced through neutralization of pickling waste solutions of irons and steels, etc. under the specific conditions thereby changing the colloidal irons hydroxide contents to crystalline irons oxide contents.  
     CONSTITUTION: Slurry of neutral sludge produced through neutralization of pickling or rinsing waster solutions of irons and steels is controlled to pH7 to 11 and is blown with air under temperature above 60°C, whereby it is thermally oxidized. This causes the precipitation of colloidal iron hydroxide of large volumes and weights to change to a small amount of crystalline iron oxide. If this is dehydrated, the amount of waste sludge becomes slight and the cost of waste treatment is saved.

Title: Electronic watch with speaker
Inventor: AMAKAWA HIDEKI
IPC: G04C21/02
Filed: 1979-06-26
Abstract: PURPOSE:To attain reproduction of broad frequency range by a miniature speaker by controlling the resonance frequency of the speaker by providing inside of a speaker vibration system parts that are movable with an electric signal. CONSTITUTION:Right before a melody tone is reproduced, driving pulses obtained by dividing the electric signal of a quartz oscillator are applied to coil block 9 so that sound emission opening part 7b with a resonance point that corresponds-to a driving frequency will come in contact with opening part 1a of resonance box 1, thereby turning stepping motor shaft 8. Since resonance-point adjustment piece 7 couples with shaft 8, the position of rotation agrees with shaft 8 and any position can be obtained by controlling a rotation pulse current. For the purpose, sound- emission opening part 7b that corresponds to the frequency can be made to agree with resonance box opening part 1a to obtain various resonance frequencies. Consequently, a melody tone of sufficient reproduction band width can be generated without reference to the size of the speaker, by driving diaphragm 2 by coil 5.

Filed: 1988-04-04
Abstract: PURPOSE:To check a dosage monitor circuit itself at all times and enhance the reliability by connecting together the open ends of a high voltage electrode and a measuring electrode by a means such as a resistor. CONSTITUTION:Within an electric dissociating box 1 a resistor 7 is connected between open ends of a high voltage electrode 2 and a measuring electrode 3 and a high voltage power supply 4, the high voltage electrode 2, measuring electrode 3, and a measuring display 5 constitute a closed circuit to allow flowing of current at all times, which is displayed on the mentioned measuring display 5. Thus current is allowed to flow at all times through the resistor 7. This permits the measuring display 5 to check abnormality of the high voltage power supply 4 and discontinuity in a connection cable 6 at all times in the form of variation in the standing current value whether there is irradiation with radiations to be measured, and in the event of any abnormality, a dosage monitor circuit can be interlocked and irradiation with the radiations to be measured be stopped, which accomplishes a cheap dosage monitor circuit with high reliability.

Title: Brake pressure controller
Inventor: KADOSAKI SHIROU
IPC: B60T8/66
Filed: 1993-03-16
Abstract: PURPOSE:To provide a brake pressure controller which does not worsen control accuracy even if an abnormality occurs in a ground car speed sensor. CONSTITUTION:When a ground car speed sensor is normal, a target slip rate alphais set to 12% (S4), and a target wheel speed VR is operated based on ground car speed VGS and the target slip rate alpha (S5). If the ground car speed sensor is abnormal, the target slip rate alpha is set at 5% (S7), and the target wheel speed VR is operated based on assumed car body speed VSO (S8). Since shift amount of the assumed car body speed VSO is smaller than that when the ground car speed sensor is normal, the assumed car body speed VSO is lower than ground car speed VGS, but the target wheel speed VR is not deviated largely from running speed of a vehicle. Delay in start of an antilock control becomes small, fluctuation of brake pressure is reduced, and wheel speed is reduced and its fluctuation is reduced to avoid deterioration of control accuracy.

Title: Method of regulating asynchronous fuel injection in acceleration of electronically controlled fuel injection engine
Inventor: ITOU HIROSHI
IPC: F02D41/10
Filed: 1983-05-10
Abstract: PURPOSE:To prevent fuel from becoming overrich in the sharp acceleration of an engine in which asynchronous fuel injection is performed in the acceleration of the engine, by controlling the number of times of continual fuel injection depending on the rotational number of the engine. CONSTITUTION:In a step S1, it is judged from the change in the degree of opening of a throttle valve whether asynchronous fuel injection should be effected in the acceleration of an engine. If it is judged that the asynchronous fuel injection should be effected, the number of times of the asynchronous fuel injection to be continually effected depending on the rotational frequency of the engine is determined in a step S2. In a step S3, a series of asynchronous fuel injection within the determined number of times are effected. The fuel is thus prevented from becoming overrich in the sharp acceleration of the engine.
