Patent JP-H03188392-A (JP)
Title: Receiver
Inventor: YASUDA KENTARO
IPC: G01S3/781
Filed: 1989-12-18
Abstract: PURPOSE:To prevent false detection by outputting a false detection signal when a voltage output of each divided reception band from a component analyzer shows the difference from a preset determination value that exceeds an allowable range. CONSTITUTION:A received electromagnetic wave 101 emitted from an object having a temperature and caught by an antenna is led to a wide-band amplifier 2 of a receiver 1 and amplified. This amplified electromagnetic wave inside a reception band is sent to a detector 3 and a component analyzer 5. The electromagnetic wave inside the reception band is detected by the detector 3, and the detected wave is outputted as a direct-current electromagnetic wave intensity signal 103 corresponding to the intensity of the electromagnetic wave, while it is led to a comparator 4. The comparator 4 compares the voltage of the electromagnetic wave intensity signal 103 with a voltage set beforehand, and when the voltage of the electromagnetic wave intensity signal 103 exceeds the set voltage value, it outputs a detection signal 102 showing that the electromagnetic wave emitted from a target is contained in the received electromagnetic wave.

Title: Adaptive controller having recurrence system parameter adjusting rule
Inventor: MAKI HIDETAKA
IPC: F02D41/04
Filed: 1992-11-16
Abstract: PURPOSE:To make possible an adaptive control by a short sampling cycle with the use of a low level microcomputer and to improve the stability of control accuracy and a controller by inputting the input value of a parameter identifying/adjusting mechanism by multiplying it by a prescribed factor other than 1. CONSTITUTION:The range of the value of an intermediate variable that is possible to reach is determined by the input zeta (k) to a parameter adjusting mechanism. After zeta (k) is multiplied by a prescribed factor C1 other than 1 in order to change the range of the value of the intermediate variable that is possible to reach, it is inputted to the parameter adjusting mechanism. For instance, the value of an intermediate variable GAMMA (k) is in inverse proportion to the square of the factor C1. At this time, thetahat (k) to be the output of the parameter adjusting mechanism is uniquely determined by only a control plant and the same output is imparted to a controller even if the values of zeta (k) and y (k) are multiplied by the factor. In this way, the range of the value of the intermediate variable that is possible to reach can be limited.

Filed: 1991-11-19
Abstract: PURPOSE:To obtain the telephone set in which noise due to continuous ringing is blocked by providing a means stopping an incoming tone during ringing and releasing the tone after lapse of a prescribed time in the telephone set. CONSTITUTION:Upon the detection of an incoming call at an incoming call detection section 101, a CPU 112 allows a speaker 106 to sound the incoming call tone through relays B, A. Then the CPU 112 monitors the stop of an incoming call signal due to give-up of a caller via the incoming call detection section 101, monitors a reply through an off-hook detection circuit section 109, and monitors the entry of a ring tentative stop command from a key matrix 110. Upon the detection of the entry of the ring tentative stop command, the CPU 112 turns off the relay A to stop the incoming call tone ringing and starts a timer 111. At the expiration of the timer, the relay A is again activated. When the incoming call signal still comes from a trunk line 200 at that point of time, the incoming call tone is sounded out from the speaker 106.
