Title: Packet coding system
Inventor: SUZUKI JUNJI
IPC: H04Q11/04
Filed: 1987-10-30
Abstract: PURPOSE:To improve the reproduction quality at packet aborting by preparing separately coders and decoders for odd number and even number samples and replacing the decoded value of other packet by an interpolated value even if the even number or odd number of samples of packets are aborted. CONSTITUTION:A packet received from a packet network 6 is decomposed at first at the reception side and the obtained coded signal is inputted respectively to an odd number sample decoder 9 and an even number sample decoder 10. If packet aborting takes place, since the code corresponding to the odd number sample cannot be recognized, the operation of the decoder for odd number sample is stopped during this period. Thus, the final output is obtained by arranging the decoded value of even order sample and an odd number interpolated sample obtained by interpolating the even sample decoded value by a waveform interpolation circuit 12 alternately and outputting the result by a switch 13. Thus, the deteriorated quality attended with packet aborting is reduced.

Filed: 1994-11-09
Abstract: PURPOSE: To prevent a drain hose or the like on the side of a sink base from being broken by the effluence of a high temperature water by performing an on/off control of a heater by a high control water temperature during the periods of washing and rinsing when fed water is at a low temperature while control is made to start the discharging of water after the temperature of water is lowered due to the fed water following the washing and the rinsing. CONSTITUTION: When a washing course is started, a control section turns on a washing pump 8 to actuate an operation timer, and then, a delay timer is operated. When delay time is reached, the temperature of water in a washing chamber 3 is measured with a temperature sensor 25 to be defined as the temperature of supply water. The temperature of the supply water is compared with a reference water temperature and, when the temperature of the supply water is above the reference water temperature, the heater 9 is on-off controlled so that the temperature of the water is maintained until the washing time is judged to pass. Then, after the washing time is passed, the heater 9 is turned off and it is judged whether the temperature of the water in the washing chamber 3 is below the water temperature of forbidding the effluence.  When the water temperature is below the water temperature of forbidding the effluence, the washing pump 8 is turned off to discharge water.
