Abstract: A power supply device includes a driving control device and an auxiliary control device, the vehicle including a main power source, an auxiliary power source, and a supply path, the supply path being a path configured to be opened and closed according to a state of a start switch of the vehicle. The driving control device is a device that controls a state of equipment installed in the vehicle and the auxiliary control device is a device that controls a state of the auxiliary power source. The driving control device is configured to execute a storage process, a permission signal transmission process, and an initial value process, and the auxiliary control device is configured to execute a permission signal reception process and a stop process.

Abstract: A control device for a vehicle includes a plurality of control circuits configured to control a control object by starting in response to powering-on of a vehicle and to perform power latch control for continuing to be supplied with electric power in a predetermined period in response to powering-off of the vehicle. Each of the control circuits is configured to perform starting after all of the control circuits have recognized the powering-on of the vehicle in a case where the vehicle is powered on while the power latch control is being performed after the vehicle has been powered off.

Abstract: A steering control device includes a control circuit configured to control driving of a reaction force motor that generates steering reaction force applied to a steering wheel in which power transmission with turning wheels of a vehicle is separated. When a vehicle power source is turned on, the control circuit requests a vehicle control device to stop traveling of the vehicle when information is exchanged with the vehicle control device in a manner that does not follow a predetermined pattern.

Abstract: A closed reactor for the thermal cracking of heavy oils, having an internally mounted, rotatable injection pipe. The injection pipe is adapted to spurt preheated raw material under pressure against the inner wall surfaces of the reactor while rotating to remove coke which has deposited on the reactor walls during the previous cracking operation.

Abstract: In a process for the thermal cracking of a heavy hydrocarbon in a cylindrical reactor, a portion of the content material in the reactor is taken out and injected back into the reactor according to a specific procedure to form a "wet wall" or liquid curtain on the inner peripheral wall of the reactor, thereby preventing coking in the reactor. The apparatus includes a radially outwardly extending interior annular recess around an upper portion of the inner wall thereof and forming a part of said inner wall and plural means for tangentially injecting the recycled liquid into said recess.

Abstract: A method for the batch thermal cracking of heavy oils, such as steam blowing for production of binder pitch, employing a reactor having a rotary injection pipe which is rotatable within the reactor. Upon completion of the thermal cracking and withdrawal of the reaction product, the injection pipe ejects preheated raw material under pressure against the interior wall surfaces of the reactor while in rotation to remove coke which has deposited on the reactor walls during the previous cracking operation.

Abstract: A rotary pump for hot pitch, asphalt and like viscous solidifiable material, having a cylindrical outer extension on a packing gland to provide an elongated passage around a driving shaft, thereby allowing leaking material to solidify and be reduced into powder before falling from the outer end of the packing gland.
