Inventor: HIGUCHI HISAO
IPC: C10L5/00
Filed: 1981-03-19
Abstract: PURPOSE: To obtain an additive for a petroleum coke/water slurry, which is capable of forming stable slurry without causing coagulation and settlement and having a low viscosity, from lignosulfonic acid or its salt.  
     CONSTITUTION: As an additive, lignosulfonic acid (A) or its salt (B), e.g., an alkali metal salt (Li, Na, or K), a lower amine salt (methylamine, ethanolamine, etc.), or ammonium salt, is used. About 0.01W5wt% lignosulfonic acid (or its salt) is added to an aqueous slurry of petroleum coke (at least about 70wt% thereof passing through a 200-mesh sieve) to obtain a high-concentration (about 50W 70wt%) petroleum coke/water slurry in which the petroleum coke particles are well dispersed.

Title: Acoustic sailing target
Inventor: MIMORI MIKIO
IPC: G01S15/74
Filed: 1984-03-02
Abstract: PURPOSE:To obtain the acoustic sailing target with good operability by providing a can body which sails by itself with an active transmission responding device and a passive false signal generating device. CONSTITUTION:A sonar sound is received 5 and stored in an acoustic controller 7 temporarily, and when the sonar sound is ceased, a signal of the same frequency and with the same pulse width with the sonar sound stored in the controller 7 is transmitted from a transmitter 4 through an amplifier 3 after level adjustment 8. The level of the adjusting device 8, on the other hand, is preset with an operation button on a console panel 9, so a coefficient of sonar reflection is set optionally. Then, the operation button on the panel 9 is operated to set the functions of the controller 7 to a passive system, and then an electric false signal generated by the controller 7 is adjusted 8 and transmitted 4 through the amplifier 3. Then, temperature, a sailing speed, etc., are stored in the sailing controller 10 before this device thrown in water, and the controller 10 controls a power motor 11 and a servo motor 13 according to the program of the stored information to operate a screw 12 and an underwater wing 14. Thus, the acoustic sailing body with good operativity is obtained.

Title: Fuel injection device for diesel engine
Inventor: TAMAI KATSUYUKI
IPC: F02B3/06
Filed: 1993-02-26
Abstract: PURPOSE:To improve reliability by forcibly increasing fuel pressure inside a common rail to a valve-opening pressure of a safety valve or more when an operation condition detecting means detects effection of a specified operation condition, and thereby preventing generation of rust on the safety valve. CONSTITUTION:When a key switch is set OFF, an ECU (electronic control unit) 31 starts to count passing time, and judges whether or not the passing time reaches a preset value. Until it reaches the preset value, an injection amount of a fuel injection valve 10a is controlled such that idling operation can succeed, and a discharge amount of a high pressure pump 2 is increased to the extent that a fuel pressure inside a common rail 8 exceeds a valve-opening pressure with certainty. When the passing time reaches the preset value, a safety valve 12 is forcibly opened. The safety valve 12 is thus forcibly opened at every stoppage of an engine 1, thereby preventing generation of rust and adhesion of a steel ball to a valve seat.

Abstract: PROBLEM TO BE SOLVED: To prevent an alternate instruction stored in a peripheral RAM area at the time of executing a program memory relieving operation from erroneously being rewritten at the tiem of data access. SOLUTION: The circuit has CPU 11, peripheral RAM 13, outer RAM 14, an alternate address register 15, an alternate address comparison circuit 16, an alternate instruction address register 17, an alternate address selection circuit 18, a memory address comparison circuit 19, a memory address selection circuit 1A, and an instruction alternate control register 1B. At the time of executing reading from or writing in an address (alternate instruction storage address) where an instruction (alternate instruction) instead of a bug instruction detected in a program memory is stored in the execution of a program memory relieving operation, the alternate instruction in a peripheral RAM 13 area is read in an instruction read cycle. In a data access cycle, reading and writing is executed on outer RAM 14 connected to the outside of a micro computer.  Thus, the alternate instruction in the peripheral RAM 13 area is prevented from erroneously being rewritten.

Title: Hyperthermia apparatus
Inventor: OKUMURA YOSHITAKA
IPC: A61N1/40
Filed: 1988-02-22
Abstract: PURPOSE:To properly heat a region to be treated by mounting a plurality of applicators for emitting an electromagnetic wave arranged in parallel and an electric field change- over means for changing over the electric field emitting directions of the applicators. CONSTITUTION:Two applicators AP1, AP2 having the same constitution are arranged so that the opening parts OP1, OP2 thereof are brought into contact with each other at a predetermined angle in a state turned in the same direction. Since the electric fields emitted from the applicators AP1, AP2 are negated each other at the part where two applicators AP1, AP2 are brought into contact with each other, the intensity of an electric field becomes small. When one applicator AP1 is arranged so as to be rotated by 180 deg., the electric fields emitted from the applicators AP1, AP2 become ones having the same amplitude and opposite phases. Therefore, since the electric fields emitted from the applicators AP1, AP2 are intensified each other at the part where the applicators AP1, AP2 are brought into contact with each other, the intensities of the electric fields become large. As mentioned above, by changing over the electric field emitting directions of the applicators, a large number of different heating patterns can be formed and a region to be treated can be properly subjected to hyperthermia.
