Title: Refrigeration type compressed air dehumidifier
Inventor: HATSUTORI TETSUNAO
IPC: B01D53/26
Filed: 1980-02-02
Abstract: PURPOSE: To raise the performance of apparatus as well as prevent its wasteful operation by a method in which two cooling chambers are provided in parallel and as the amount of imcoming air increases under a condition that the first cooling chamber with an evaporator is frozen, compressed air is by-passed to the second cooling chamber.  
     CONSTITUTION: In case where the amount of incoming air as a load is normal, compressed air passes through the first cooling chamber C 1  in which an evaporator 11 is incoporated, where it is cooled and dehumidified by heat exchange with the evaporator 11. But, when the first cooling chamber C 1  is frozen due to the reduction of the amount of imcoming air, the incoming air is by-passed to the second cooling chamber C 2  without evaporator as the amount of incoming air increases, where it is cooled and dehumidified by heat exchange with frozen moisture. Also, while dehumidification occurs in the second cooling chamber C 2 , defrosting takes place and also cooling and dehumidification are performed, and then refrigerator is stopped. Thus, regardless of the state of imcoming air, stable and continuous operation of dehumidifier can be always carried out and also its power consumed can be greately reduced.

Title: Digital frequency shift circuit
Inventor: YAMAMOTO HIROAKI
IPC: H04N5/44
Filed: 1988-01-22
Abstract: PURPOSE:To stabilize the frequency shift by multiplying a carrier having a frequency being the subtraction of a frequency shift from the sampling frequency when the frequency shift exceeds the Nyquist limit, passing the carrier through a filter and obtaining a signal subjected to a desired frequency shift. CONSTITUTION:The frequency shift carrier is set to a frequency FS-mu being the subtraction of the desired frequency shift mu from the sampling frequency FS. Then the carrier is multiplied with the input signal Ein to apply the frequency shift to the carrier by a multiplier 11 and the multiplication output is selected by a filter 12. Thus, even in the frequency shift of a digital signal in excess of the Nyquist limit where the frequency shift exceeds the Nyquist limit, the frequency shift is applied in an excellent way even by using a very simple constitution. Moreover, the cost, power consumption, the circuit scale and data delay or the like are reduced.

Title: Video/sound signal recording and reproducing device
Inventor: SEKIMOTO KUNIO
IPC: H04N5/7826
Filed: 1984-01-26
Abstract: PURPOSE:To obtain both video and sound signals of high quality with no variance by simple constitution by reproducing the sound signal to be processed with a preceding pair of heads to change it into the original one and then reproducing the video signal with a delayed pair of heads. CONSTITUTION:A head 9' is delayed by (1 frame + 1/3 field) for signals Y and a1 which are reproduced by a heat 9. These reproduced signals are amplified by a reproduction amplifier 11 and then demodulated by a frequency demodulator 13. Thus a reproduced signal Y is obtained at an output terminal 16. While the signal a1 reproduced by the head 9 is amplified by a reproduction amplifier 30 and converted into an original analog signal by a PCM demodulator 32. At the same time, error correction processing is given to the analog signal. Then the analog signal is delayed until it is coincident with the timing of the reproduced signal Y and obtained at an output terminal 34. Thus the signal Y and a sound signal of a channel 1 having coincident timing are obtained at a Y signal output terminal 16 and an a1 signal output terminal 34 respectively.
