Title: Digital image expansion system
Inventor: ASANO MASANARI
IPC: H04N19/91
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To effectively convert images by reducing the amount of data to be prepared in the case of performing expansion to the images of various sizes based on the compression data of the images and shortening the processing time for inverse quantization in the case of generating reduction images. SOLUTION: A decoding part 1 Huffman decodes and run length decodes the compression data of one block and generates quantized data Ruv. The quantized data Ruv form the matrix of 8×8 for instance. Since Huffman encoding and run length encoding are reversible encoding, the decoded quantized data Ruv are completely the same as the quantized data Ruu at the time of performing JPEG(joint photographic expert group) compression. A reduction part 2 omits the high frequency component of the quantized data Ruv and performs conversion to the matrix of a small dimension. Thus, the amount of the data to be prepared is reduced in the case of performing the expansion to the images of the various sizes based on the compression data of the images.  Then, in the case of generating the reduction images, the processing time for the inverse quantization is shortened and the reduction images faithful to source images are obtained.

Filed: 1990-02-07
Abstract: PURPOSE:To replenish a necessary liquid heating medium corrected in temp. by changing the position of a liquid level detector to the liquid level corresponding to the change of liquid temp. by a temp. sensor. CONSTITUTION:A sample is alternately and repeatedly immersed in low and high temp. tanks receiving liquid heating media respectively cooled and heated by a cooler 2 and a heater 3 to perform a heat shock test. At this time, the position of a liquid level detector 6 is set to the positions of the reference liquid levels 8a-L, 8a-H at the room temps. of the respective low and high temp. tanks and a reference level falls and rises to a position 8b by the respective cooling and heating of the liquid heating media supplied thus far and, at the time of the completion of the test, the liquid level becomes a position 8c by consumption. The liquid heating medium is supplied so that the liquid level becomes the position 8b for the next test. With the change of the output of a corresponding temp. sensor 5, the output to a liquid level indicator 7 of a control rod 10 changes and the exciting power of an electromagnetic coil 11 changes to move the detector 6 to the position corresponding to liquid temp. By this automatic control, an accurate test can be performed and liquid replenishing labor can be saved.

Title: Frequency retransmitting system
Inventor: KORI TAKEJI
IPC: H04B7/208
Filed: 1985-02-15
Abstract: PURPOSE:To eliminate instability of a local oscillator by using the 1st local oscillator to recover a carrier from a reception signal after frequency conversion, modulating the carrier, using the 2nd local oscillator to shift the frequency and using again the 1st local oscillator to apply frequency conversion. CONSTITUTION:When a frequency fluctuation of a signal frequency (frequency FL) of a local oscillator 19 is selected as DELTAFL, a reception signal (frequency FR) is frequency-converted into FR-(FL+DELTAFL) and the result is inputted to a demodulation circuit 9. The carrier in the frequency FR-(FL+DELTAFL) recovered by the demodulation circuit 9 is outputted to a modulation circuit 7 and a shift local signal (frequency FS) shifts the frequency by the frequency difference (FS=FT-FR) between the transmission signal (frequency FT) and the reception signal. The signal is subject to frequency conversion into FR-(FL+DELTAFL)+FS +(FL+DELTAFL) by a signal of the common local oscillator 16 again. The frequency of the transmission signal is FT=FR+FS and the effect of the frequency fluctuation DELTAFL of the common local signal is lost.

Title: Filtration system
Inventor: ETO MASAHIRO
IPC: B01D65/02
Filed: 1991-02-20
Abstract: PURPOSE:To increase a filtration flux when filtering a feed fluid containing suspended material by installing a filter membrane support on the fed liquid side of the filter membrane and installing as a filter membrane support on the permeated liquid side a nonwoven fabric and a construction forming a groove in which the permeated liquid flows. CONSTITUTION:A filter membrane support 30 is installed approximately coming into contact with a filter membrane 28 in the direction parallel to the flow one of a feed liquid on the feed liquid side of the filter membrane 28 so that the flow of the feed liquid may not be obstructed. Thereby the distortion of the filter membrane 28 when backwashed through a backwash liquid inlet 27 is made small and suspended material 29 deposited is completely removed. A nonwoven fabric support 47 is installed on the permeated liquid side of a filter membrane 49 and a groove 48 leading to a permeated liquid outlet 46 is formed in a construction supporting the support 47. Therefore, after the permeated liquid passes through the filter membrane 49, it passes through the nonwoven fabric 47 by a small distance to the groove 48 and the permeated liquid reaching the groove 48 flows in the groove 48 to a permeated liquid outlet 46. Thereby, when backwashing, since the resistance of the filter membrane 99 to the permeated liquid agent is small to allow the backwash liquid to flow easily, a filtration flux can be sufficiently recovered.
