Title: Apparatus for measuring distance by doppler radar
Inventor: SHIMADA TADASHI
IPC: G01S13/58
Filed: 1982-07-07
Abstract: PURPOSE:To measure a relatively short distance simply and inexpensively, by a doppler radar having two antennae, two counting parts for measuring frequency and an operation part for calculating a distance. CONSTITUTION:When DC bias voltage is applied to a gun diode 11, electric waves are emitted from antennae A1, B1 by oscillation and the reflected waves from an object are received by the antennae A1, B1 while dopplar frequencies DELTAf1, DELTAf2 are obtained from the amplitude of the encircling line of the transmitting and receiving waves thereof. These waves are rectified by a mixer diode 10 and amplified by obtaining AC of the doppler frequencies to be shaped to a pulse waves by wave form shaping devices A4, B4. Pulse lines are counted by counting parts A5, B5 to read the frequencies DELTAf1, DELTAf2 and enter an operation circuit A6 to calculate the distance of the object to be measured. This distance is compared to a preliminarily set distance issueing an alarm and a distance stopping a moving object by a comparator A7 and alarm or stop treatment is taken by the output thereof.

Abstract: PURPOSE:To perform the judgment of the large leak and the medium leak of a body with excellent reliability, by detecting the change in vacuum degree when the inside of an airtight container, wherein the body having an airtight chamber is enclosed, is evacuated. CONSTITUTION:A semiconductor device 1, which is sealed in a hollow package, is enclosed in a port 2. A leak valve 3 is closed, and the inside of the port 2 is evacuated by a vacuum pump 4. At this time, the temporal change of the vacuum degree is detected by a vacuum gage 5, and the result is displayed on a vacuum degree display device 6. The signal is further processed by a CPU7, and the vacuum degree characteristics are stored in a memory device 8. In the memory device 8, the vacuum degree characteristics for a perfect airtight body which has the same volume as that of the semiconductor 1, are stored. Said characteristics and the measured vacuum degree characteristics are compared, and the quality of the semiconductor device 1 is judged. Since a visual test is not performed, the judgment of the large leak and the medium leak can be performed with excellent reliability.

Title: Data transmission equipment
Inventor: OKANO HIROSUKE
IPC: H04N7/035
Filed: 1987-05-15
Abstract: PURPOSE:To send out a signal to which an error correction code is added and a code to which the code is not added with high efficiency by switching a means which sends out data together with the added code for error correction and a means which sends out the data as it is. CONSTITUTION:Eight-bit data is switched by a switching circuit 6 with the data with the error correction code in its original form without being divided by four bits, and converted from parallel to serial simultaneously with the time base conversion of a time-base converting circuit 7, and the data is outputted at the same rate with a clock, etc., and applied to a synthesizing circuit 9. At this time, a read clock is switched by a clock switching circuit 8 because there is a difference in timing between the case wherein eight bits are generated by adding the error correction code to each four-bit data and the case wherein the eight-bit data is used as it is without being processed. Those three kinds of signals are switched with a signal from a timing switching signal generating circuit 10. Consequently, the signal to which the error correction code is added a code to which the code is not added are sent out efficiently.

Abstract: PURPOSE:To considerably improve the throughput by connecting plural microprocessor units, each of which consists of the same kind of microprocessor, an instruction converting circuit, and a conversion control circuit which controls the conversion mode of the instruction converting circuit, to a bus. CONSTITUTION:If trouble occurs in an MPU 7 while the MPU 7 executes the processing of a subroutine A, a trouble signal is sent to a CTL 2 through a trouble signal line 11, and this trouble signal is reported to an MPU 6. When detecting the occurrence of trouble in the MPU 7 by an interrupt, the MPU 6 changes the conversion mode of a CCV 4 to MOD 2 through a bus 8 to perform the interrupt processing, and instruction CALL A in address 200 is fetched at this time if necessary. Instruction CALL A in address 200 read out by the CCV 4 is not converted and is sent to the MPU 6 and is executed. As the result, the processing of the subroutine A starting with address 500 is executed by the MPU 6 to execute the processing of the MPU 7.
