Title: Garage guidance device for vehicle
Inventor: NAKAMURA MITSUO
IPC: G01C21/26
Filed: 1992-05-14
Abstract: PURPOSE:To provide the vehicle garage guidance device which guides the vehicle into a garage by continuous steering wheel operation and gives a smooth driving feeling. CONSTITUTION:A laser scanner 15 set on the vehicle 12 measures the coordinates and attitude angle of the vehicle to the garage and calculates a guidance line. The steering wheel 17 is driven toward the guidance line under the command of an ECU 16 and the vehicle coordinates are calculated from the steering wheel angle and movement distance data. In this state, the coordinates and attitude angle when the steering wheel is fully turned are estimated and the radius of such a turn that the vehicle moves onto the center axis in the garage is found from the estimated values; while the radius of the turn becomes the minimum radius of a turn of the vehicle, the steering wheel 17 is driven at an equal speed in the largest reverse direction to make a circular turn. During this circular turn, the attitude angle when the steering wheel is rotated to the center is estimated from the calculated vehicle coordinates and when the garage center axis matches the attitude angle, the steering wheel is turned to the center at an equal speed and the vehicle travels straight inwardly in the garage.

Title: Operating device for ac motor
Inventor: NIWA TORU
IPC: H02P27/06
Filed: 1985-06-05
Abstract: PURPOSE:To complete the start of a motor in a short time by setting the output voltage of an inverter to a rated voltage until the start of the motor is completed, and reducing the output voltage after the start is completed. CONSTITUTION:Since a large accelerating current flows immediately after an induction motor 2 is started, a detected current from a voltage detector 5 is larger than the reference value from a reference value setter 61. Thus, a comparator 6 does not output a modulation command, and the output of an inverter 4 is accordingly maintained at rated voltage. Then, when the start of the motor 2 is completed, i.e., the motor 2 arrives at the normal speed so that the detected voltage becomes the reference value, the comparator 6 outputs a modulation command to an amplitude modulator 7, thereby reducing the amplitude of a sinusoidal signal, resulting in a decrease in the output voltage of the inverter 4.

Title: Melt reduction method
Inventor: YAMADA KENZO
IPC: C21B11/00
Filed: 1986-05-29
Abstract: PURPOSE:To efficiently recover the heat generated by secondary combustion to a metal bath by burning the carbonaceous material blown into a slag layer by gaseous O2 to reduce ore and subjecting the formed gaseous CO to a secondary combustion in the slag layer by the gaseous O2 blown thereto. CONSTITUTION:The carbonaceous material and ore are blown together with the gaseous O2 through a top blowing lance 7 into the furnace of a converter type of a melt reduction furnace and the carbonaceous material is burned in the slag layer 3 to reduce the ore and to form the metal bath 2. The gaseous O2 is further blown from tuyeres 4 for secondary combustion into the slag layer 3 and the gaseous CO formed by the combustion of the carbonaceous material is secondarily burned in the slag layer 3. The sensible heat of the secondary combustion is thereby directly absorbed into the slag layer 3 and is transmitted to the metal bath 3 and the heat generated by the secondary combustion is efficiently recovered in the metal bath 2.

Title: Production of cold rolled steel plate
Inventor: HINOTO HAJIME
IPC: C21D9/663
Filed: 1980-09-05
Abstract: PURPOSE:To reduce and remove stuck scale simultaneously with decarburization by cold rolling a steel plate which is held stuck with hot rolling scale then subjecting the same to box annealing in the tight coil state in a non-oxidative atmosphere. CONSTITUTION:A steel plate which is held stuck with hot rolling scale is subjected to direct cold rolling under good rolling lubrication, whereby the steel plate of black surfaces covered with fine powder scale is obtained. Thence, this steel plate is held in the tight coil state and is subjected to box annealing in a non-oxidative atmosphere. The annealing temps. are kept at >=550 deg.C. Thereby, the black scale is reduced together with the decarburization of the carbon in the steel, whereby the scale-free steel plate is obtained. If the content of carbon in the steel is excessively small, the sufficient reduction does not take place and therefore about >=0.005wt% is the preferable content of carbon. If necessary, the steel plate may be subjected to skin pass rolling.
