IPC: G06F3/00
Filed: 1983-03-28
Abstract: PURPOSE:To avoid the transfer of wrong data by using a means to detect the transfer of wrong data due to the external noises, etc. produced during the transfer of data and a means to invalidate the wrong data. CONSTITUTION:If a defective clock is supplied together with a nondefective clock 12 during the transfer of data due to the external noises, etc., the number of clocks exceeds nine. Outputs A and D of a counter 2 are simultaneously set at logical 1 at all times when a one-shot multivibrator 1 is active. In this case, the output of an NAND circuit 4 is set at logical 0. Therefore a reset signal 16 is set at 0. The counter 12 is reset to its initial state with the signal 16, and no counter end signal is delivered from an AND circuit 6 since the output D of the counter 2 is logical 0 when the operation of the vibrator 1 is over. Thus the input is prevented for the wrong data.

Filed: 1987-03-05
Abstract: PURPOSE:To improve sensibility by forming the central section and end side section of a pressure sensitive element in thick sections, shaping sections except said central section and end side section in second thin sections and arranging the central section of the pressure sensitive element onto the upper surface of a first thin section in a pedestal. CONSTITUTION:With a pressure sensitive element 3, a central section 3b and end side sections 3c are formed in thick sections, sections except said central section and end side sections are shaped in second thin sections 3a, and the central section 3b of at least the pressure sensitive element 3 is disposed onto the upper surface of a first thin section 1a in a pedestal 1. That is, since pressure P applied from a pressure introducing hole 1b deflects the thin section 1a in the pedestal 1 and displaces the thick section 3b of the central section of the pressure sensitive element 3, stress is generated in gages 4, and a resistance value changes in response to the stress, thus sensing pressure. Accordingly, sensibility is improved because the thin sections 3a are formed to the pressure sensitive element 3 even when the thin section 1a in the pedestal 1 is not thinned, and strength is increased and workability is also enhanced because the thickness of the peripheral sections 3c of the pressure sensitive element 3 is thickened.
