Title: Vehicle body slip angle assuming device
Inventor: HIRANO YUTAKA
IPC: B62D137/00
Filed: 1992-01-09
Abstract: PURPOSE:To improve the accuracy of assumption by a device which assumes vehicle body slip angle beta at the center of gravity of the vehicle. CONSTITUTION:This device includes a sensor 40 which detects lateral acceleration Gy1 of the center of gravity, a sensor 42 which detects lateral acceleration of a point that is forward from the center of gravity by a distance (s), a sensor 34 which detects the vehicle speed V, a sensor 36 which detects the yaw rate gamma, and a controller 50. The controller 50 assumes vehicle body slip angle betacontinuously, and obtains YM/IZ from Gy1, Gy2 and s, where YM denotes yawing moment and IZ -- yaw moment of inertia. Present value beta(i) of beta is assumed by composing an observer against an observable linear constant system, in which beta and gamma assumed relative to the plane motion of the vehicle are state variables, and Gy1/V and YM/IZ-beta(i-1) are input variables, where beta(i-1) means assumed previous value of beta.

Title: Manufacture of silicon-steel ring material
Inventor: SUGITANI JUNICHI
IPC: H01F41/02
Filed: 1987-01-30
Abstract: PURPOSE:To make a process to form a laminate unnecessary by a method wherein a molten metal of silicon steel is poured into a mold so that a crystal structure, which is grown inside the mold in the diameter direction due to the directional solidification proceeding toward the center from the external circumference, can be formed. CONSTITUTION:An ingot of silicon steel is formed in the same manner as in the case of ordinary silicon steel; an appropriate amount of Si is prepared at about 0.5-4.5 %y if a molten metal of silicon steel is poured into a mold, a temperature gradient which proceeds toward the center from a face coming into contact with the mold is caused at a bulk of the molten metal; a pillar-shaped crystal is produced along the temperature gradient due to the directional solidification proceeding toward the center from the external circumference. As the mold, a metal mold is used in order to promote the directional solidification due to the temperature gradient; as a casting process, either of a stationary casting process and a centrifugal casting process can be applied. That is to say, a molten metal M is poured into a centrifugal casting mold 10 which is mounted on revolving drive wheels 20, 20; the molten metal is solidified by centrifugal revolution around the axial center of the mold 10; a hollow-cylindrical cast body is obtained. By this setup, a process to laminate thin sheets and to punch them to unite the thin sheets by welding, or the like is not required.

IPC: H02P5/00
Filed: 1978-02-27
Abstract: PURPOSE: To promote the reducting of torque ripple, by such means that, two position detectors, with an electrical angle set shifting 2π/3, be provided, with this output signal controlling on-off a semiconductor of the power inverter.  
     CONSTITUTION: An AC input is rectified by a power rectifier 1, being smoothed out by a reactor 2 and inputted to a power inverter 30. The power inverter 30, for instance, is to be constructed by a gate turn-off thyristor (GTO). A rotary disc of position detectors 5A, 5B, mechanically connected to a synchronous motor 4, is made shifting by an electrical angle of 2π/3 on said motor same shaft, with the position detector 58 outputting a delay signal. A logic circuit 10A transmits β o  set signal to pass a drive circuir 11A turning on the GTO at the timing of β o . And a logic circuit 10B transmits a signal, with an electrical angle delayed by 2π/2 from β o , to pass a drive circuit 11B turning off the GTO. The period, from on to off of the GTO, of 2π/3 becomes a period during which the GTO is conducted, with β o  made capable of setting to zero, causing the synchronous motor 4 to be able to operate with a power factor of 1, thus capable of widely reducing the torque ripple.

Title: Multiplexed television signal transmission equipment
Inventor: HOSHINO KIYOSHI
IPC: H04N7/00
Filed: 1989-01-31
Abstract: PURPOSE:To prevent a part where the interference of an added signal is made conspicuous, and a part where the interference is not made conspicuous, from being generated in correspondence to the level of a main signal by controlling the compressibility of the added signal in correspondence to the level of a main signal. CONSTITUTION:When a signal (B1, B2) is (0, 0), namely, when the voltage level of a luminance signal is smaller than a reference voltage RV1, a selector 236 selects the output signal, for which a coefficient value is 0.4, of a coefficient circuit 235. Samely, when the signal (B1, B2) is respectively (1, 0), (0, 1) and (1, 1), by selecting the output signals of coefficient circuits 234-232, a high area component is compressed more largely the smaller the voltage level of the luminance level is and the high area component is compressed less the larger the voltage level is. In such a way, to the high area component receiving amplitude compression in correspondence to the voltage level of the luminance signal, orthogonal modulation is executed by a multiplier circuit 16 and after that, the high area component is supplied to an adder circuit 13 and frequency- multiplexed to a center signal. Thus, the interference of the high area component can be prevented from being conspicuous.

IPC: G06V30/146
Filed: 1982-02-15
Abstract: PURPOSE:To decide whether characters are written longitudinally or laterally, by comparing the longitudinal coorelation between picture elements with the lateral correlation. CONSTITUTION:A reader 202 performs a raster scan on an original 201 to generate a level 0 for white and a level 1 for black through photoelectric conversion, and the resulting picture information 203 is stored in a picture information memory 204. A lateral OR circuit 205 and a longitudinal OR circuit 209 read one row and one column of picture information out of the memory 204 respectively to OR black elements of every block of a prescribed number of picture elements divided by the indication of a decision part 206, and the results are stored in a lateral block information memory 207 and a longitudinal block information memory 210. The numbers of blocks when the circuits 205 and 209 generate AND outputs with the level 1 are counted by a lateral count memory 208 and a lateral count memory 211 and stored therein. The decision part 206 finds the ratio R between the counted values of the memories 208 and 211 to vary the number of picture elements and performs said process repeatedly, thereby deciding characters are written longitudinally when 1-R>alpha(alpha=constant) and laterally when 1-R<alpha.
