Title: Differential pcm transmission system
Inventor: WAKAMATSU KUNIO
IPC: H04N19/50
Filed: 1984-08-27
Abstract: PURPOSE:To eliminate the delay of a rise part of a picture signal and to attain transmission of signals of high quality, by inserting a PCM signal of a prescribed bit which performs no DPCM coding directly to the rise part of each scan cycle of the picture signal when the picture signal undergoes the differential PCM coding at the transmission side and at the same time giving no DPCM decoding to the prescribed bit of the rise part of each scan cycle of the signal received and demodulated at the reception side and using a PCM signal as it is for reproduction. CONSTITUTION:When the transmission of picture signals is started, a switch circuit 17 is changed to the side of a frame memory 12 according to the output of a counter 18 just for a period equivalent to several bits from a rise time point of each scan line of the picture signal. Thus the PCM signal delivered from the memory 12 and underwent the DPCM coding is supplied as it is to a modulation circuit 14. For a receiver 20, the PCM signal underwent the DPCM decoding is supplied to a frame memory 23 since a switch circuit 29 is switched to the side of a modulation circuit 31 by a counter 30 just for a period of serveral bits from the rise time point of each scan line of the signal sent from a transmitter 10. Then said PCM signal is used for reproduction of picture signals through a D/A converter 24.

Title: Sulfonation of heavy oils
Inventor: MIYAZAWA KUNIO
IPC: C07C309/62
Filed: 1989-07-11
Abstract: PURPOSE:To sulfonate a heavy oil with sulfur trioxide while effectively remov ing the reaction hest and suppressing the production of by-products by bringing the heavy oil into contact with the suffer trioxide in the coexistence of a solvent dissolving the heavy oil and a low boiling point organic compound not reactig with the sulfur trioxide. CONSTITUTION:A heavy oil is brought into contact with sulfer trioxide in the coexistence of a solvent (e.g. CS2) dissolving the heavy oil and an organic com pound (e.g. pentane or acetone CS2) having a low boiling point (<=70 deg.C) in an amount of >=5wt.% based on the solvent at 0-70 deg.C to sulfonate the heavy oil. Since the reaction heat is efficiently removed by the coexistence of the low boiling point organic compound and the reaction proceeds mildly, side reaction products such as a sulfone and thermal polymerizate can be suppressed and the water-soluble sulfonated heavy oil can be prepared in a high purity. Since the reaction heat is effectively removed, the amount of the solvent for dissolving the heavy oil can be reduced and the size of the plant can be made smaller.

Filed: 1982-10-12
Abstract: PURPOSE:To inspact a photo-mask accurately by obtaining measuring patterns, the directions of measurement therefor are varied at a unit of 45 deg., from the picture data of the photo-mask and detecting the changes of each pattern. CONSTITUTION:A photo-mask is read by a scanner and the picture data are obtained, and the data are binary-coded and memorized. The direction of reading is turned at the unit of 45 deg. in the memorized picture data, and four measuring patterns are acquired. The number of times where each measuring pattern is changed into values corresponding to the conductor section and non-conductor section of the photo-mask is detected, and the parity of the number of times is discriminated and ''0'' is outputted on an odd number and ''1'' on an even number. Each output is 1 because the measuring pattern values change twice in all of the directions of reading (a)-(d). The defects of the photo-mask such as a pin hole are detected by combining outputs corresponding to each measuring pattern.

Abstract: PURPOSE:To improve working efficiency by letting centrifugal force radiate abrasives out of an impeller, which are supplied into the impeller rotating within a rotor case, projecting them directly or indirectly into a projection path case, and striking its opening section against the surface where the heads of bolts appear. CONSTITUTION:A motor is driven so as to rotate a shaft 20 in the state where the opening section 34 of a projection path case B is directly or indirectly stricken against the surface 5 through which bolt heads 4 appear. Resultantly, an impeller 18 starts rotating at a high speed accompanied with the rotation of a rotor 21 concurrently at the same speed.

Abrasives projected are rotatably accelerated by blades 23 of the rotor 21 in the rotor case 11 so as to be projected into the projection path case B, then, are projected horizontally, obliquely upward and obliquely downward by a division plate 31 so as to be evenly projected over the opening section.

Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To further enhance radiating performance of an overall double tube type oil cooler by devising cooling water side heat transfer efficiency by effectively utilizing a fastest part of a flowing velocity in a flow of the water flowing out from a tube to heat exchange with oil without reducing a radiating area. SOLUTION: A double tube type oil cooler 1 is installed in an extension line of an outer diameter size (WT) of a tube 2 in a lower tank 3 of a radiator, i.e., in a fastest part of a flowing velocity in a flow of cooling wafer flowing out from the tube 2. And, a sectional shape of the cooler 1 is formed in a short flat elliptical shape having a shorter size of the short axis along a width direction of the tube 2 than the axis along a lengthwise direction of the tube 2. Thus, even in the case of the cooler 1 having small size in the width direction, a surface area of an outer wall surface of an outer cylindrical tube 11 in contact with the water is increased to suppress a decrease in radiating area.
