Abstract: PURPOSE:To provide the subject machine wherein a vibration generating element connected to a vibration generating body through a vent hole opened in a heating cylinder is arranged to contact a molten resin thereby to enable rapid degassing at the vent-hole, and reduce the size of the vent hole and make the vent up difficult. CONSTITUTION:At a vent hole 3 provided at the intermediate of a heating cylinder 1 a vibration generating element 10 vibrated by means of an oscillating coil 12 is arranged to come into contact with a molten resin 11. The resin 11 is imparted with vibration at the vent hole 3, and by this vibration a cavitation occurs in the molten resin and the separation of a volatile component is accelerated, the volatile component in the molten resin being rapidly degassed and exhausted in the atmosphere through a vacuum pump 17. Even when the resin produced no cavitation, the formation of the resinous film hindering the degassing of the volatile component is suppressed by the resin agition effect due to the vibration.

Title: Digital filter
Inventor: YAMAGATA KENJI

Filed: 1987-05-28
Abstract: PURPOSE:To reduce the number of digits of input/output data as suppressing the lowering of the accuracy of an arithmetic operation, by providing the number of digits larger than prescribed number of digits at a storage circuit, supplying the prescribed number of digits out of storage data to a subtractor and the output terminal of a filter as preceding data, and supplying the storage data to an adder as the preceding data. CONSTITUTION:A new coefficient CX is obtained by adding a value YZ stored in a register 6 and a value Y2H stored in a register 9H by a computing element ALU5, and it is stored in a register 12. The coefficient CX set at the register 12 is supplied to a multiplier MLT1 via a gate G1. Audio data is inputted to the input to the other side of the multiplier MLT1, and an input/output characteristic as an expander similar to that of an analog CX decoder can be obtained at the output of the multiplier. In other words, bit expansion is performed on only a processing part relating to a coefficient in a digital filter, and another processing is performed with the number of digits of inputted data. Also, the same number of digits as that of the input data is outputted. In such a way, the lowering of computing accuracy can be suppressed comparatively, and also, it is possible to form the constitution of the whole of a circuit by matching the number of digits with that of the data of the circuit at the front and rear of the digital filter.

Filed: 1990-05-25
Abstract: PURPOSE:To assure an amount of supplying oil to a compressor by a method wherein a high pressure discharging gas is bypassed by a bypassing capillary to an accumulator and refrigerant stored in the accumulator is agitated. CONSTITUTION:When a surrounding air temperature and an indoor air temperature are low during a freezing cycle, an evaporation temperature of an indoor heat exchanger 5 is low during a cooling operation, an evaporating temperature of an outdoor heat exchanger 4 is low during a heating operation, and a refrigerant accumulated in an accumulator shows a low temperature, the refrigerant shows a temperature range where a two-phase separation may easily occur. Thus, normally, a discharging pipe 10 is connected to the first bypassing capillary 8 selected to cause an amount of discharging gas bypassing the accumulator 3 to become appropriate value, thereby the refrigerant in the accumulator 3 is agitated and even if the temperature in the accumulator enters a region where the two-phase separation occurs, a returning amount of oil to the compressor 1 is not decreased and then a stable amount of returning oil to the compressor 1 can be assured.

Filed: 1979-10-17
Abstract: PURPOSE:To increase the bit ratio of the memory access, by forming the buffer memory into two segments in the ROM semiconductor circuit which contains both the ROM and the buffer memory on the same chip. CONSTITUTION:The buffer memory which stores temporarily the data given from the ROM array 22 consists of two segments 25 and 26. The raw of the ROM array is applied to the raw address decoder 20 from the address register 18, and the data of the array 22 is written into the segments 25 and 26 of the buffer memory. In this case, the raw address is held at the register 18. As a result, the next row address input 16 is compared with the data of the register 18 through the control circuit 36, and if a coincidence is obtained, the reading can be eliminated for the ROM array. Thus the column address input 35 receives the decoding 35 and multiplexing 29, and the data given from the segment 27 is taken into the output buffer.
