Title: Atm switch and method for managing buffer for atm cell
Inventor: SAKAGAMI KENJI
IPC: H04Q3/00
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To provide an ATM switch that manages a buffer with less hardware. SOLUTION: A flow signal generating section 50 is newly provided with overflow registers OVF#0-OVF#7 corresponding to logic queues LQ#0-LQ#7. A coincidence detection circuit compares counter values of cell counters CC#0-CC#7 with threshold values of threshold value registers THR#0-THR#7. In the case that the counter values are coincident wit the threshold values, a state of an overflow flag register OVF#X corresponding to the register is switched alternately to a set state and a clear state. The overflow flag registers OVF#0-OVF#7 discriminate whether or not the count of the logic queues LQ#0-LQ#7 exceeds the threshold value.

Title: Electrinic oven
Inventor: TAKAZUME MASAFUMI
IPC: F24C7/02
Filed: 1977-12-05
Abstract: PURPOSE: To control the microwave heating output and uniformly heat food, by utilizing a fixed relation between the central temperature and the peripheral temperature of the food.  
     CONSTITUTION: When a temperature setting unit 2 is set at an optional temperature and a power switch is turned on, the output of a temperature comparator 3 goes to a high level because the temperature of a thermistor 1 is lower than the set temperature. At that time, a time detector 4 starts counting. Since the counted time is shorter than a set time, the output of a time comparator also goes to a high level. In addition, the inputs A, B of a gate 7 go to a high level. An AC control element is turned on by the output of the gate 7 through a driver 8 to cause a magnetron to oscillate. When the temperature detected by the thermistor 1 has reached the set temperature, the output of the temperature comparator 3 is inverted to a low level. Then, the magnetron stopo oscillating and the counting by the time detector 4 is stopped because of the output inversion of the temperature comparator 3.

Title: Pitch extractor
Inventor: FUJII SHIGEKI
IPC: G10L25/90
Filed: 1988-06-16
Abstract: PURPOSE:To perform stable and smooth pitch extraction in a wide pitch range by multiplying inputted acoustic signals by stability and inputting the multiplied results to a pitch extracting means as signals which are more emphasized in large amplitude and low frequency. CONSTITUTION:Upon receiving digital acoustic signals from an A/D converter 1, an EC value calculating section 4 calculates an EC value. The EC value is the total sum of the sample values of all sampling points between two continuous zero-crossing points in the signals. The EC value is inversely proportional to the frequency, but proportional to the amplitude. By utilizing such characteristics, therefore, the EC value is multiplied by the original digital signal outputs by means of a multiplier circuit 6 for calculating stability. As a result, no output is outputted at the time of no sound, but outputs which are more emphasized in large amplitude and low frequency are outputted from a multiplier circuit 5 when sounds exist. A self-correlating section 7 calculates self-correlating functions and outputs the calculated functions to a pitch discriminator at every sample. A pitch deciding section 8 estimates a pitch period from the output of the section 7. If the stability is high when a pitch abruptly changes, the pitch output is outputted to the outside.
