Patent JP-H0511048-A (JP)
Title: Ultrasonic-wave distance sensor
Inventor: BIREI KENJIRO
IPC: G01S15/10
Filed: 1991-07-01
Abstract: PURPOSE:To make it possible to detect distances highly accurately in a broad detecting range with a single ultrasonic-wave piezoelectric transducer by changing the strength of the transmitted ultrasonic-wave pulse when an output voltage exceeds a threshold voltage. CONSTITUTION:An analog voltage which is proportional to a distance is outputted based on the measurement of the elapsed time from the periodic transmissions of ultrasonic-wave pulses from an ultrasonic-wave piezo-electric transducer 1 to the returning of the reflected waves from a body to be detected to the transducer 1. At this time, when the body to be detected approaches the transducer 1 within a detecting range, the output voltage is decreased in proportion to the distance. When the voltage becomes lower than the threshold value of the voltage corresponding to the detecting distance, a signal A from a gate-signal output port 11 is changed to B. Thus, bidirectional switches 92 and 102 are turned ON, and the strength of the transmitted ultrasonic wave pulse is made weak through resistors 72 and 82. The effect of the reverberation of the ultrasonic wave pulse can be made small. Therefore, the detecting range can be changed by changing the strength of the transmitted ultrasonic-wave signal with one transducer 1, and detection can be performed in the broad range.

Title: Constitution of inter-job shared load module
Inventor: MATSUDA RYUICHI
IPC: G06F9/44
Filed: 1986-07-09
Abstract: PURPOSE:To produce a shared program with no recompiling by using a rearrangement means which replaces the reference address of an inter-job shared program when said address is used as an actual address. CONSTITUTION:An inter-job shared program is loaded to a real memory device 7 as follows. That is, a load module is supplied (S18) and it is decided whether or not the load module is the first one in this system (S19). If so, an inter-job shared area is loaded to the device 7 (S20). Then the area of a reference address is replaced so that the area of a defining address is equal to that loaded actually. Thus the addresses are rearranged by a rearrangement means. In such a way, the addresses are rearranged for each job and therefore the inter-job shared program can be produced with no transfer of registers nor recompiling.

Filed: 1984-07-30
Abstract: PURPOSE:To permit automatic reception of various television system signals with a single television receiver by discriminating the various television system signals with discriminating means such as PAL/NTSC, 50Hz/60Hz. CONSTITUTION:A color carrier signal CW and a burst signal BU are fed to a PAL/NTSC detection circuit 11. When an NTSC signal inputs, an output of the detection circuit 11 is a zero level. When a PAL signal inputs, however a signal, which becomes high for each one horizontal scanning line is outputted to the detection circuit 11. With this difference, the PAL and NTSC systems are discriminated from each other. A field frequency detection circuit 12 further outputs a discrimination output A2 representing either 50Hz or 60Hz as the field frequency. Further, a detection circuit 15 discriminates a voice carrier signal. The individual discrimination outputs are fed to a mode switching circuit 16, which can produce switching signals S1 to S4 according to the detected television system.
