Title: Bit error detecting and correcting circuit
Inventor: KATAGIRI HIDEKI
IPC: G06F11/08
Filed: 1990-03-16
Abstract: PURPOSE:To improve the reliability of data by providing a bit error generating circuit which generates a bit error in input data and an error state deciding circuit which decides detection and correction processing operation for the bit error with error bit information outputted from an error detecting and correcting circuit. CONSTITUTION:When forcible error generation is specified in bit error detection and correction mode through a forcible error generation specification control line 9, the bit error generating circuit 6 inverts one bit of an input signal and outputs the inverted signal. When the bit error generating circuit 6 generates an error, an error detecting and correcting circuit 2 decides the error, and outputs its error detection signal to an error detection signal line 5 and error state data to a bus 4 for a redundant bit. Then an error state decision circuit 7 decides whether or not the error state data is obtained by comparison to decide whether or not the error detecting and correcting circuit 2 operates normally, and outputs the result to an error state decision line 8. Consequently, the operation state of a bit error detecting and correcting circuit 2 is recognized efficiently and the reliability of a data signal is improved.

Filed: 1984-04-02
Abstract: PURPOSE:To prevent chattering phenomenon by switching a frequency immediately in response to a threshold level higher than a body detection level, and holding the level above the body detection level as far as a body is present even if a reflected wave and a detouring wave becomes opposite phase with each other momentarily. CONSTITUTION:A power amplifier 5 drives an ultrasonic wave transmitter 6 with a signal of one frequency of an oscillation circuit 4. The 2nd comparator 11 discriminates the output of an ultrasonic wave receiver 7 with a detection level highe than the detection level of the 1st comparator 10 and supplies a switching signal to a switch circuit 3. When the body 12 comes to before a transmission part, an ultrasonic wave transmitted by the transmitter 6 is reflected by the body 12 and when the signal after amplification 8 and detection 9 increases above a set threshold level, comparators 11 and 10 generate outputs according to respective threshold levels. Thus, the frequency is switched to obtain the level higher than the body detection level as far as the body 12 is present even if the reflected wave and detouring wave becomes opposite phase with each other, preventing chattering.

Title: Oxide film forming method and electronic device
Inventor: MINAMI HIROAKI
IPC: C23C14/08
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the unevenness of the surface of a film by applying vapor deposition to a substrate by the bias sputtering method and successively applying vapor deposition by the ion beam sputtering method. SOLUTION: At first, a metal oxide film 7 is formed on a substrate 1 by applying the vapor deposition by the bias sputtering method. Successively a metal oxide film 8 is formed on the film 7 by applying the vapor deposition by the ion beam sputtering method. Since the high purity oxide is deposited on the surface by the ion beam sputtering method, the film quality becomes uniform regardless of the position. Then, at the time of chemical polishing after film forming, the formed oxide film is etched at a uniform speed even at any position and the surface is smoothly worked. In such a case, it is preferable that the thickness of the film 8 formed by the ion beam sputtering method is controlled to 1-10% of the thickness of the film 7 formed by the bias sputtering method in order to completely bury the pits (recessed part).

Filed: 1984-04-06
Abstract: PURPOSE:To enhance working efficiency, by performing filtering by gravity at the initial stage and utilizing vacuum in filtering when filtering by gravity becomes impossible and further automatically performing operation for changing over gravity and vacuum. CONSTITUTION:The liquid 27 to be filtered injected from a liquid injection port 20 is filtered under gravity by filter paper 7. When the liquid 27 to be filtered is supplied in an excessive amount as compared with a filtering speed or filtering by gravity becomes impossible by the clogging of the filter paper 7, the level of the liquid to be filtered rises to push up a float 23 and a lower limit switch 22 is operated to bring the interior of a hermetically closed tank 1 to a vacuum state to increase filtering action. When the clogging degree of the filter paper 7 increases and the liquid 27 to be filtered is prevented from falling, the level of the liquid to be filtered further rises and an upper limit switch 21 is operated by the float 23 to blow compressed air P into the hermetically closed tank 1 to return vacuum to atmospheric pressure. Further, the filter paper 7 is fed out by a length corresponding to the clogging generated part.
