Abstract: PURPOSE:To miniaturize a low-temperature separation unit and to reduce an operating cost in recovering olefins such as ethylene and propylene from a light gas prepared as by-product from a catalytic cracking device. CONSTITUTION:A light gas containing olefins such as ethylene and propylene prepared as by-product from a catalytic cracking device is brought into contact with an adsorbent under pressure to adsorb hydrocarbons containing the olefins. The adsorbent is made in a state of reduced pressure, the hydrocarbons adsorbed on the adsorbent are at least partially eliminated and the eliminated hydrocarbons are purged out of the system. The adsorbent is further made in a state of reduced pressure, the hydrocarbon gas containing the olefins adsorbed on the adsorbent are eliminated and the eliminated hydrocarbon gas is introduced into a methane removing column attached to a low-temperature separation unit. The hydrocarbons obtained from the bottom of the methane removing column are sent to an olefin recovering distillation column, the olefins such as ethylene and propylene are separated and recovered in high purity, respectively, to recover the olefins.

IPC: H04N3/23
Filed: 1990-09-10
Abstract: PURPOSE:To realize a linearity correction circuit for linearly compensating elongation in the middle in a pattern unable to be corrected by an S-shaped correction capacitor by applying a resonance pulse to an integration circuit, generating a projecting curved voltage so as to attain waveform shaping, shaping the upper part of the waveform to be flat through the use of a clip circuit and superimposing the shaped voltage onto a signal in the S-shaped correction capacitor.

Abstract: PROBLEM TO BE SOLVED: To maintain bulb position accuracy high in an orthogonal direction to a light axis even in a vibration environment such as a vehicle traveling time without the deterioration of bulb fixing work in a bulb fixing structure fixing a bulb to a reflector by bayonet-engaging a bulb fixture with an annular wall of the reflector. SOLUTION: At a bayonet engagement completion time (a), the outer periphery face of a bulb base 16A is three-point supported by one pair of bulb abutting portions 30a, 30b formed on an annular wall 30 and an elastic press piece 44 formed on a bulb fixture 32. One pair of protrusion portions 46, 48 formed on the bulb fixture 32 abut the outer periphery faces of overhang portions 30d, 30e for engaging with the bayonet formed on the annular wall 30. Since the protrusion portions 46, 48 are departed from the overhang portions 30d, 30e before the bayonet engagement (b), a play in a diameter direction is produced between the bulb fixture 32 and the annular wall 30. Thereby, the setting of the bulb fixture 32 and turning work on the way to the bayonet engagement are facilitated. And the elastic force of the elastic press piece 44 can be set high by that much.

Title: Production of monodisperse copolymer
Inventor: WATANABE OSAMU
IPC: C08F212/14
Filed: 1992-08-19
Abstract: PURPOSE:To produce a monodisperse copolymer which meets the requirements of a polymer for a resist material by subjecting a specific monomer and styrene to anionic polymn. and eliminating CH2OCH3 groups from the resulting copolymer. CONSTITUTION:This monodisperse copolymer comprising structural units of formulas II and III is obtd. by subjecting a monomer of formula I and styrene to anionic copolymn. and eliminating CH2OCH3 groups from the resulting copolymer. The anionic copolymn., though can be conducted in a nonsolvent system, is pref. conducted in an org. solvent to facilitate the control of reaction rate. Eliminating CH2OCH3 groups is easily carried out by dissolving the copolymer obtd. by the copolymn. in a solvent (e.g. acetone or water) and adding an acid (e.g. hydrobromic acid) dropwise to the resulting soln. The elimination reaction causes neither the breakage of the polymer main chain nor crosslinking between the polymer molecules, resulting in a monodisperse copolymer.

Abstract: PURPOSE:To contrive the improvement of the throughout of a packet exchange signal and to shorten the delay time by moving to a boundary between a line exchange area and a packet exchange area decided separately according to the traffic state of line exchange and packet exchange. CONSTITUTION:The boundary is set in a frame and divided into two areas, a line exchange signal uses a 1st area CS only and a packet exchange signal uses a 2nd area PS and the dead slot of the 1st area CS.

Title: Seal device for impeller of turbo refrigerating machine compressor
Inventor: OOMACHI YUUJI
IPC: F25B1/00
Filed: 1983-12-23
Abstract: PURPOSE:To reduce the frictional loss of a disc remarkably and improve the efficiency of the turbo refrigerating machine by a method wherein refrigerant gas, having a small specific weight, is contacted with the outer surfaces of a center plate and a side plate with a low pressure at all times to seal the inner and the outer diametral parts of the impeller. CONSTITUTION:When the impeller 16 is rotated by a pinion shaft 17, a pressure gradient is generated from the inner diametral side toward the outer diametral side of a part, which is sealed by the labyrinth seals 27, 28, 32, 32 of seal members 24, 25, since a clearance delta1 between the impeller 16 and the center plate 16A as well as the clearance delta2 between the side plate 16B and the seal member 25 are small while the pressure of the outer diametral part balances with the pressure of the suction tube 31 of the compressor and the pressure of the inner diametral part becomes lower than the pressure in the suction tube 31. According to this method, the refrigerant gas, having a small specific weight, contacts with the outer surfaces of the center plate 16A of the impeller 16 and the side plate 16B of the same with a low pressure, therefore, the frictional loss of the disc for the impeller 16 may be reduced further than before and the efficiency of the turbo refrigerating machine may be improved.
