IPC: B62D6/00
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To decide the displacement amount of the neutral position of a steering angle sensor utilized to a steering control precisely. SOLUTION: The energy consumption of an electric motor 21 when right/left rear wheels RW1, RW2 are steered in a left direction and right direction is detected by that a current sensor 38 detects the current flowing from a drive circuit 41 to the electric motor 21. An electric control circuit 42 decided by a program processing the displacement amount of the neutral position of a sensor 37 for the neutral state of the said rear wheels RW1, RW2 in response to the difference of an energy consumption for a prescribed time between a time when a detection steering angle detected by a rear wheel steering angle sensor 37 represents the steering in the left direction of right/left rear wheels RW1, RW2 and a time when it represents the steering in the right direction. A detected steering angle detected by the steering angle sensor 37 is corrected by this displacement amount.

Filed: 1981-01-20
Abstract: PURPOSE:To constitute so that every IC has the same characteristic and no adjusting terminal is required at all, by using the physical quantity of kT/q as reference voltage or a reference potential difference. CONSTITUTION:In 2 MOS transistors, the ratio ID/(W/L) of a drain current ID to a channel part pattern ratio W/L(W and L denote channel length and channel width, respectively) is made different.

Title: Semiconductor input-output circuit
Inventor: MATSUKUMA MOICHI
IPC: H01L21/8238
Filed: 1994-01-26
Abstract: PURPOSE:To reduce the deterioration or breakdown of a semiconductor input- output circuit by a surge voltage while reducing the possibility of the occurrence of a latch up phenomenon. CONSTITUTION:When a surge voltage is applied to an external connecting terminal Pb, a protective P-channel MOS transistor TP or a protective N- channel MOS transistor TN is turned on and, as a result, the protective capacitor CP on the highest potential side or the protective capacitor CN on the lowest potential side is connected to the terminal Pb. The internal capacity connected to the terminal Pb is increased and the surge voltage divided by the internal and external capacities of the terminal Pb is reduced. During normal operation, the operating speed of a semiconductor input-output circuit is not deteriorated, because the transistor TP or TN is turned off and the capacity of the terminal Pb is suppressed.

Title: Paper supply device
Inventor: ITO KENJI
IPC: B65H1/26
Filed: 1986-01-16
Abstract: PURPOSE:To make a paper feed position empty and to make it possible to mount and remove a paper feed cassette, separately, by arranging a paper feed container, rotatably and movably between a paper feed position on one side surface of a paper feed device and a paper replenishing position on the front surface of the device. CONSTITUTION:When a paper feed container 10 is set at a paper feed position, an inclined surface y1 of a cam section 12c abuts against a release pin 75, and therefore it pushes up a pick-up roller 30 together with a frame 71. When the container 10 is completely set, the release pin 75 falls into an inclined surface y2 so that the pick-up roller 30 makes into press-contact with the upper surface of stacked paper sheets P by its dead weight. When the paper container 10 is moved away from the paper feed position, it is reversed. When the paper feed container 10 is started to rotate and move from the paper feed position to the paper replenishing position, the rotation of the container 10 causes the pick-up roller 30 to be raised to a some degree. Therefore, when the paper feed container 10 is moved away from the paper feed position, the pick-up roller 30 is surely separated from the uppermost one of the stacked paper sheets P, thereby it is possible to prevent the uppermost paper sheet P from adhering to the pick-up roller so that it is left alone.

Abstract: PURPOSE:To prevent disturbance of a picture due to noise by a method wherein, when the speed of a moving body is delayed and a ratio of noise contained in a code analyzed by an analyzer is high, instead of the code, an average code is used to display speed distribution of the moving body. CONSTITUTION:A power comparator 311 inputs a power (p) from a color Doppler analyzer 121 and compares the power with given threshold p0 to input a result to a frequency selecting circuit 313. A frequency (f) is inputted from the analyzer 121 to the selecting circuit 313, and it is selected according to the comparing result of the comparator 311 whether the frequency (f) is outputted as it is or after it is reduced to zero, and a result is inputted to a frequency averaging circuit 315. The circuit 315 determines an average frequency in a given time, and selects a code (s), analyzed by an analyzer 121, when the average frequency exceeds a given threshold. Based on the code and the average frequency, speed distribution of a moving body is displayed. When it is below the given threshold, an average code calculated by a code averaging circuit 321 is selected, and based on the average code and an average frequency, speed distribution of the moving body is displayed. When the speed of the moving body is delayed and a ratio of noise contained in the code (s) is high, an average code is selected instead of the code.
