Title: Phase shifter
Inventor: SAKAI TETSUO
IPC: H03K5/13
Filed: 1986-10-17
Abstract: PURPOSE:To stably obtain an output rectangular wave with an orthogonal phase relation with respect to an input rectangular wave by making an average output potential of an output signal of a 1st operational amplifier equal to that of a reference signal of a 2nd operational amplifier and selecting each component of an integration element so as to apply ideal integration by the 1st operational amplifier. CONSTITUTION:The impedance of a capacitor C1 is selected so as to be sufficiently to the resistance of a resistor R1 and resistors R2 and R3 are selected as an identical resistance. Thus the bias offset voltage due to the bias current of the amplifier 2 is canceled and the output DC potential(average output potential) of the operational amplifier 2 is made equal to the reference potential and the impedance of the capacitor C1 and the resistor R2 are nearly neglected and the ideal integration using the operational amplifier 2, the resistor R1 and the capacitor C2 is applied. Even when the voltage and frequency of an input rectangular waveform signal 100, the power supply voltage and constants of each component are subjected to change due to temperature drift or the like, the orthogonal relation between the input rectangular wave signal 100 and an output rectangular wave signal 300 is unchanged and the 90 deg. phase shift always stable is attained.

Title: Reference voltage generating circuit
Inventor: SUGINO HIROYUKI
IPC: G11C11/407
Filed: 1985-10-30
Abstract: PURPOSE:To form a constant voltage generating circuit which generates a constant voltage with small temperature dependency by generating part of the constant voltage by utilizing a difference in threshold value having no temperature dependency. CONSTITUTION:This circuit is the same as before except that a voltage of 50V at a terminal is applied to one input of a comparing circuit 102 encircled with a dashed line, i.e. the gate of an N-MOS 8. The voltage applied to the gate of the N-MOS 8 is at 50V, so voltages V 30NEW and V 40NEW at terminals 30 and 40 are different from those in a conventional example and shown by equations 1 and 2. The V 40NEW does not depend upon a negative source voltage VSS and is a constant voltage determined by a current value I0 and transistor characteristics of an N-MOS 12. Further, the low voltage V 40NEW is determined only by the temperature dependency of an N-MOS 12.

Inventor: ISONO HIROSHI
IPC: B60T7/02
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To detect abnormality on an operating force detector without operating any operational member. SOLUTION: A treading force detector including a load sensor is provided for a brake pedal, and let the reaction of an operating rod be acted when the brake pedal is footed, so that treading force is thereby detected. Pre-load is applied to the treading force detector by a spring in a state that the braking pedal is out of treading operation. The pre-load is so set as to be in the allowable deviation range of a detected value based on allowable errors in gain equivalent to an allowable zero point drift range based on allowable zero point drift, and the reference range of detection for abnormality by the treading force detector is so set as to be equivalent to each aforesaid reference range. Both the zero point drift and the error in gain are regarded as normal as far as the detected value is in the reference range in a state that the brake pedal is out of treading operation.  Even if both the zero point drift and the error in gain are abnormal, the detected value goes out of the reference range, so that the treading force detector is found to have been abnormal.
