But such movement is directly checked by a separation roller 9 which is not rotated. The lowermost sheet S1 brought into contact with a belt 7 among the sheets S is moved by feed of the belt 7, because the friction factor mu of the belt 7 is larger than the friction factor mu2 between the sheets. When the leading end of the sheet S1 reaches between the belt 7 and the roller 9, the sheet S1 to which the feeding force of the belt 7 is given is not kept from advancing by the separation roller 9, but transported, because the friction factor mu of the belt 7 is larger than the friction factor mu1 of the roller 9.

Title: Method for adjusting uniformity of static magnetic field
Inventor: HATANAKA MASAHIKO
IPC: A61B5/055
Filed: 1987-08-11
Abstract: PURPOSE:To suppress the non-uniformity of a static magnetic field, by saturating a component other than a specific atomic nucleus before obtaining the magnetic resonance signal of the specific atomic nucleus. CONSTITUTION:Prior to exciting an atomic nucleus having magnetic resonance frequency omega0 used as static magnetic field uniformity adjusting data, a high frequency pulse having frequency different by deltaomega is applied to an object to be examined to excite the component B of chemical shift delta and, after a generated magnetic resonance signal is allowed to disappear, the magnetic resonance signal of a component A is generated by a high frequency magnetic field having frequency omega0. By this method, a component other than an object to be measured is brought to a preliminarily saturated state and a specific atomic nucleus used in adjustment is excited. When this magnetic resonance signal is used, the non-uniformity of several-ppm order of a static magnetic field can be adjusted.

Abstract: PURPOSE:To speedily detect a mutant adeninephosphoribosyltransferase (APRT) included in serum or urea of a patient of the APRT breakage with high sensitivity thereby enabling short-time measurement of a large quantity of checking bodies by using a peculiar antibody to a normal enzyme (N-APRT) and a mutant enzyme (M-APRT) of the APRT. CONSTITUTION:N-APRT or M-APRT used in this method is obtained by crushing and extracting human red blood corpuscles. The cleaned red blood corpuscles are homogenized through freezing and melting, crushed by ultrasonic waves, and centrifuzed by a supercentrifugal. Then, the supernatant liquid is processed through ion exchange, affinity chromatography by GMP-agarose and gel permeation chromatography, so that 136,000 by the molecular weight is obtained. The 125th to 145th of the N-APRT and M-APRT are combined by solid phase peptide synthesis. A mouse is immunized by using this as an antigen. A monoclonal antibody to be bonded only with the N-APRT and that to be bonded only with the M-APRT are produced. Furthermore, the APRT is refined and the mouse is immunized by the obtained enzyme.

Title: Solid-state image pickup device
Inventor: MATSUNAGA MASAYUKI
IPC: H04N5/335
Filed: 1982-11-16
Abstract: PURPOSE:To prevent the generation of smear by providing two switch elements in series for row and column selection between each photosensitive picture element and a signal charge read line and giving sequentially a signal charge on the read line to an output line. CONSTITUTION:When one column selecting line 201 is driven by a vertical register 19, MOS switches 13 for column selection are all turned on. A row selecting line 18 is driven sequentially from the left by a horizontal register 17 and MOS switches 12 for row selection are turned on sequentially from the left. Since switches 13 are all turned on in this case in advance, the stored signal charge of a photodiode PD11 for one column's share is read sequentially on a read line 141 and outputted seuqnetially from a terminal 16. Similarly, the signal charge of each column is outputted sequentially. When a strong incident light is given to the PD11(1,1), a part of excess charge flows to the read line 141 via the switches 12(1,1),13(1,1) and superimposed on all the output signal charge to prevent the generation of smear.

Title: Waste heat recovering device
Inventor: SUMITOMO HIROYUKI
IPC: F01K7/00
Filed: 1984-09-26
Abstract: PURPOSE:To increase an amount of a power recovered, by a method wherein, in a device which recovers heat from hot water exhausted from a factory by a Rankine cycle utilizing a low temperature difference, high temperature oil is injected during a process in that working medium steam flows from the suction hole of an expander to an exhaust port. CONSTITUTION:Working medium steam, which is heated and vaporized in a vaporizer 13 by means of hot exhaust water serving as a heat source, is fed to an oil injection type screw expander 11 to serve therein so as to drive a load 12 such as generators. In which case, high temperature oil, heated by a heater 17, is injected through nozzles 19, mounted in a multistage, in a process in that the working medium steam flows within the expander 11 from a suction hole to an exhaust hole. This forces the working medium steam to overheat in addition to provision of lubricating and sealing action. Mixture of the working medium steam, flowing through the expander 11, and oil is separated by an oil separator 14, and after the working medium steam is cooled and condensed by a condenser 15, it is returned to the vaporizer 13.

Title: Stationary induction electric apparatus
Inventor: KUMASAKA TAKAO
IPC: H01F27/28
Filed: 1983-10-28
Abstract: PURPOSE:To eliminate the possibility of generating local high temperature parts by improving the coil-cooling efficiency by uniformity of the distribution of winding flow speeds by a method wherein the whole winding is constructed by a reverse flow type flow path. CONSTITUTION:The winding 18 is divided into the first and section winding sections from below by arranging in its axial direction a partition 23 which blocks inside and outside vertical ducts 5 and 6 at the same time. In each section, a cooling fluid is let flow in through one of said ducts, led to each horizontal duct 7, and then let flow out of the other vertical duct. Thereby, since all the sections of the winding are constructed by the reverse flow type flow path, the fluid supplied to each winding section can cool the coil 2 by being led to the horizontal duct; accordingly, the distribution of the flow speed in each winding section can be made much more uniform than the conventional. Therefore, the cooling effect of the winding is improved, and the local high temperature parts can be eliminated because of no generation of small speed parts in bent flow sections.

Title: Leg fixer for jack-up type working ship
Inventor: FUJISHIMA KAZUAKI
IPC: E02B17/06
Filed: 1981-12-15
Abstract: PURPOSE:To reduce the weight of legs by a method in which a tooth is provided to a rack to vertically move a support leg while engaging with a pinion attached to the hull side, and also a crosswise moving bar coupling with the tooth is provided to the hull side. CONSTITUTION:A booth 8 is provided to a rack 3 to vertically move a supporting leg consisting of cords 2 while engaging with a pinion attached to the hull side, and a crosswise moving bar 10 coupling with the tooth 8 is provided to the hull side. In fixing the leg, a jack 11 is energized, the pinion is turned while pushing the bar 10 toward the rack, and then the leg 1 is brought to a given fixing position, whereupon the bar 10 is instantaneously fitted into the tooth 8 when the position of the tooth 8 coninsides with the position of the bar 10 and the leg 1 is fixed to the hull. Thus, since most of a great bending moment applying to the leg is transmitted as an axial force through the bar and tooth to the cords and the hull, the increment of the leg cross section area can be lessened and the weight of the leg can thus be reduced.
