Title: Pitch period extracting method
Inventor: OKAMOTO SEIJI
IPC: G10L25/90
Filed: 1992-05-08
Abstract: PURPOSE:To reduce an extraction error by determining an optimum arithmetic section from an extracted period, and finding a pitch period from the 1st peak of an autocorrelation function by using a calculated autocorrelation function again. CONSTITUTION:Simultaneously with respective processes of a key-ON and key-OFF detection part 5, a pitch extraction part 6 finds a period of one pitch, i.e., a fundamental section from the 1st peak of the autocorrelation function of an inputted digital signal. Further, the pitch extraction part 6 finds the autocorrelation function of the digital signal again so as to accurately extract the pitch of the inputted digital signal according to the determined arithmetic section. Then, the pitch extraction part 6 finds a pitch period from the 1st peak of the recalculated autocorrelation function, i.e., a short section. The pitch extraction part 6 specifies, for example, the number of a key corresponding to the pitch period according to the found pitch period and outputs a signal corresponding to it.

A thin film such as  lecithin, etc. is provided on the surface of the insulation film 3 and the electrodes 2, 2' so that the  liquid crystal molecular long axis can be oriented vertical ly. Since the thickness is large in the display part, the liquid crystal is colored by the spiral structure except the part near the surface of  the electrodes 2, 2' when voltage is not applied, but when voltage is applied, the whole part is  vertically oriented and becomes colorless in the same way as the nondisplay part. Accordingly, a  color display can be executed by applying voltage to only the electrodes 2, 2' which require no  display.

Abstract: PURPOSE:To properly inform an abnormal state during food temperature detection by a method wherein an abnormal temperature change rate is determined according to the weight of food that is input from a food weight input element, and the abnormal state is informed when it is judged that the change rate of the temperatures detected by a food temperature detector is at the level of the abnormal temperature change rate.

The food temperature after a specified time No elapses is detected as T1 and set by a temperature probe 5, a magnetron 4 is put into operation, and a timer N begins to count time. When the count of the timer N reaches the specified time period No, the food temperature is detected as T2 and set by the temperature probe 5. In case the food temperature is below 90 deg.C, the difference between the food temperatures, i.e., the change amount T2-T1, is compared with the specified temperature change amount alpha for the specified time period No corresponding to the abnormal temperature change rate, and when it is judged that the change rate of the detected temperatures is at the level of the abnormal temperature change rate, the controls of a power source element 9 is stopped to stop heating by microwave, and an abnormal alarm is brought in action to inform an abnormal state of absence of the temperature probe.

Abstract: PURPOSE:To transfer a serial data by scarecely exerting influence on a program processing speed, by setting one block of the serial data as a transfer unit, and energizing a transmission/reception end signal, when the transmission and reception of the transfer unit are ended. CONSTITUTION:A transmission controlling circuit 4 sets one block of a serial data as a transfer unit, energizes a transmission end signal INTST when transmission of the transfer unit is ended, and controls transmission of the serial data. Also, a reception controlling circuit 8 energizes a reception end signal INTSR when reception of the transfer unit of the transmitted serial data is ended, and controls reception of the serial data. In this way, when a data block is being transmitted, even if an interruption processing is not executed, a transmitting data is transferred to a transmitting buffer 2 from a memory 24 when transmission of one frame is ended. Also, in case of reception, a data is written in the memory 24 from a receiving buffer 6. That is to say, the serial data can be transferred by scarcely exerting influence on a program processing speed of a microcomputer.
