Patent JP-H02223881-A (JP)
Title: Ultrasonic sensor
Inventor: SHIBATA FUMIO
IPC: G01S7/52
Filed: 1989-02-23
Abstract: PURPOSE:To detect a detection object even if the opening diameter of the sensor is small by leading an ultrasonic wave sent out of a transmitting part to a detection point by using a reflecting plate. CONSTITUTION:A reflecting plate 7 is formed by curving uniformly a plate-like body having width corresponding to an external form of a main body part 5 extending over the whole width, and its base end part is fixed in a state that the tip part covers the front of an ultrasonic vibrator 6. Also, an ultrasonic sensor 4 is used for detecting whether an object 9 exists in a detection point S or not, and can execute its detection even in the case when its object 9 has an inclined angle by providing the reflecting plate 7. In this state, when the object 9 is carried to a position of a detection point S, an ultrasonic wave (a) is reflected at a point M on the reflecting plate 7 and reaches the detection point S, and brought to specular reflection on the surface of the object 9. In this case, when the surface of the object 9 is a flat surface, it is reflected at the same point M on the reflecting plate 7 and reaches the ultrasonic vibrator 6. Accordingly, by detecting a reflected wave (b), the existence of the object 9 can be confirmed.

One of the incoming beams in the photoelectric converting surfaces of an optical detector 5 goes to be the wave surface 62 and it is arranged on a straight line X-X', which goes through a light emitting point, together width the sharing image 61. Accordingly, by executing the differential detection of the beam 62 by detectors 51 and 52, the optical head of the high reliability can be obtained.

Filed: 1990-02-27
Abstract: PURPOSE:To prevent the fluctuation of a frequency of a clock signal even if there is a jitter in a horizontal synchronizing signal by masking an undefined part generated at the time of comparing phases of a clock signal and a reference signal. CONSTITUTION:A clock signal CLK is supplied to an input terminal CIN1 of a selecting circuit 1, and a horizontal synchronizing signal HSY being a reference signal is supplied to an input terminal REF1 of the selecting circuit 1 and input terminals CIN2, REF2 of a selecting circuit 2. Subsequently, a clock signal CLKa whose phase difference to the reference signal is the smallest is selected by the selecting circuit 1, and in this clock signal CLKa, an undefined part is generated. On the other hand, when phases of the reference signals of the same phase are compared by the selecting circuit 2, after a prescribed delay time elapses, the reference signal is delayed and outputted. Therefore, based on the reference signal which is delayed and outputted, the undefined part is masked. In such a way, even if there is a jitter in the horizontal synchronizing signal HSY, the fluctuation of a frequency of the clock signal CLK can be prevented.
