Title: Switched capacitor filter for general use
Inventor: UENO NORIO
IPC: H03H19/00
Filed: 1981-12-17
Abstract: PURPOSE:To obtain a filter for general use by controlling the connection between two low pass and high pass switched capacitor filters both of which controls cut-off frequency in accordance with clock frequency. CONSTITUTION:Frequency dividers 5, 6 are connected to a low pass switched capacitor filter 1 and a high pass switched capacitor filter 2 respectively. Receiving a clock signal from a terminal clock, the frequency dividers 5, 6 changes the frequency of the clock signal in accordance with dividing ratio variable signals from terminals C1-C4 and apply the frequency-converted clock signals to the filters 1, 2 respectively. The filters 1, 2 are used independently or connected in series or parallel to obtain required filter characteristics. Since each filter can change cut-off frequency in accordance with the frequency of the clock signal, a filter having optional characteristics can be obtained.

IPC: G06T15/08
Filed: 1988-08-19
Abstract: PURPOSE:To reduce the number of conversions necessary for projection by interpolating a data which expresses the characteristic of an object at plural points in the object, converting the data into a vector expressing the characteristic of the object on the plural planes of the object, and displaying a two-dimensional picture according to the observing viewpoint. CONSTITUTION:A picture processor 14 stores a first data value to express the characteristic of the object by the plural points in the three-dimensional object from a medical picture scanner 16 into a disk device 12. The stored first data value is processed by a picture processor 14, and a second data value which expresses the characteristics of the object on the plural planes passing through the object is generated by interpolation. A run length vector having a direction and a length determined by the second data value is encoded on the respective planes. An observing means 18 converts the run length vector into a coordinate system according to the viewpoint at which the object can be observed, and it is displayed on a CRT 20 as the two-dimensional coordinates. Thus, the number of the conversions necessary for the picture projection can be reduced.

Title: Safety device for vehicle
Inventor: NIIBE TADAYUKI
IPC: G08G1/00
Filed: 1993-08-19
Abstract: PURPOSE:To evade unnecessary safety securing operation by restricting the safety securing operation unless an obstacle is positioned on a going path that a going path estimating means estimates when the obstacle almost in a stop state is detected on a travel path that a travel path estimating means detects. CONSTITUTION:When the obstacle almost in the stop state is present on the travel path of this vehicle that the travel path estimating means 14 as a result of the calculation of, for example, the relative speed as a value larger than a set value, a restricting means 16 restricts the safety securing operation by, for example, inhibition, delay, basic preparation alteration, or selection unless the obstacle is on the going path of this vehicle that the going path estimating means 8 estimates. Consequently, when the driver judges that the obstacle almost in the stop state such as a parking vehicle or pedestrian by the travel path can be passed by, the unnecessary safety securing operation can be evaded.

IPC: G06K9/62
Filed: 1981-12-18
Abstract: PURPOSE:To process the pickup of a significant point in a short time, by selecting a candidate being possible to be the significant point out of many input coordinates. CONSTITUTION:A distance calculation circuit 5 obtains a distance Ln between input coordinates from respective x, y coodinates of an input coordinate Pn inputted to a latch 3 and an input coordinate Pn-1 inputted to a latch 4. A function calculating circuit 6 inputs the distance Ln and performs function conversion so as to saturate the distance Ln over a prescribed value LM (maximum value). That is, in using a function f(x) in Equation (1) and converting the distance Ln, then the minimum point is saturated to the maximum value LM. A level comparison circuit 8 inputs a function f(Ln) of the circuit 6, inputs the last function f(Ln-1) stored in a latch 7 and obtains the level of the two values. In case of f(Ln)>f(Ln-1), x and y coordinates of the input coordinate Pn-1 stored in the latch 4 are taken as the significant point.

IPC: B41J13/02
Filed: 1985-09-19
Abstract: PURPOSE:To correctly determine the amount of thin film material to be transported even if a back roller is eccentric, by controlling a motor for transporting the thin film material based on a circumferential speed of the back roller which rotatingly contacts the thin film material. CONSTITUTION:Driving of a motor 9 causes a drive roller 6 to rotate in the direction of an arrow and a recording paper sheet 14 passes between a thermal head 4 and a back roller 5 in a state that it overlaps an ink toner film 1. At the time, the back roller 5 is rotated in the direction of the arrow following the transport of the recording paper sheet 14 so that a reflecting type photo sensor 22 produces a pulse detection signal. The pulse detection signal 234 produced by the photo sensor 22 is applied to a circumferential speed sensor 24. The circumferential speed sensor 24 counts the number of pulses of the detection signal 23 for determining the time required for a predetermined number of pulses, for example, 10 pulses. The time is required for the circumfeerential surface of the back roller 5 to rotate a predetermined distance. A motor control circuit 29 is provided with a correction signal 28, whereby it applies a pulse signal 31 corresponding to its contents to a motor drive circuit 32.
