Abstract: The present invention discloses an assist circulation apparatus and a method of its driving. Use of the apparatus of the present invention and method of its driving permits weaning from the driving or wearing of the ventricular assist device with simple operation without extreme reduction in the output per beat of the ventricular assist device being attached or severely influencing the patient's body upon recovery of the failed heart.

Abstract: An electrically conductive alumina fiber which heretofore known only as electrically insulative is now provided, which comprises an aluminum oxide matrix, and a continuous phase of carbon in the aluminum oxide matrix, the continued phase of carbon affording an electrically conductive property to the fiber. Also, a method of producing the alumina fiber is disclosed, comprising pyrolyzing a fiber of poly[(acyloxy)aloxane)] having a formula ##STR1## wherein, R.sub.1 represents CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.3, R.sub.2 represents ##STR2## or other substituted aromatic group, in an inert atmosphere.

Abstract: A method for forming patterns includes the steps of forming a first layer presenting at least one first alignment mark on a substrate and forming a second layer presenting at least one first pattern and two alignment marks on top of the first layer. The alignment marks of the second layer are independently aligned relative to the first alignment mark. The positions of the alignment marks of the second layer are measured and the deviations of such marks from preselected design positions are calculated. The substrate is moved to a corrected position determined from the calculated deviations. Finally a third layer which includes at least one second main pattern is formed on the second layer by aligning the second main pattern with the second alignment marks.

Abstract: A process for the mutual separation of volatile components in a mixture comprising at least two volatile components, comprising the steps of: (1) heating a starting liquid comprising at least two volatile components to vaporize the starting liquid and form a vapor mixture comprising the volatile component, (2) compressing the vapor mixture to cause a rise in the temperature and pressure thereof, (3) applying the compressed vapor mixture to a membrane having a selective permeability to separate the vapor mixture into a membrane-permeated fraction and a non membrane-permeated fraction, (4) indirectly placing at least one of the fractions in contact with the starting liquid of step (1) via a heat transferring wall to use the heat of the contacted fraction to vaporize the starting liquid, and (5) recovering one or both of the membrane-permeated fraction and non membrane-permeated fraction; and an apparatus for a mutual separation of volatile components in a mixture comprising at least two volatile components, com

Abstract: A novel quinaldinamide derivative having the formula: ##STR1## wherein each of R.sup.1 and R.sup.2 independently represents a lower alkyl group or R.sup.1 and R.sup.2 are combined together with the adjacent nitrogen atom to form a 5-7 membered ring; and X represents the hydrogen atom, a lower alkyl group or a lower alkoxy group, and its acid-addition salt, which show prominent central muscle relaxant effect, namely rigidity relieving effect on anemic decerebrated rigidity.

Abstract: A rocking massage chair wherein massaging wheel elements and their drive mechanism are disposed in backrest part of the chair while a motor for driving an operating shaft of the drive mechanism is disposed in seating part of the chair, whereby the relatively heavy motor is located on forward side of a rocking center of the chair so as to keep the center of gravity of the chair always on the forward side and thus to prevent the chair from overturning rearward.

Abstract: 1,3-Oxazolidine-one derivatives of the following formula ##STR1## where R is straight or branched alkyl of C.sub.3 -C.sub.8, X is hydrogen, halogen, lower alkyl or lower alkoxy and n is 4, 5 or 6, or their acid addition salts are effective for medicinal and agricultural use.

Abstract: A cash processing method is disclosed for aggregating sales data from cash processing units. Each cash processing unit has a coin counter and bill counter for accepting coins and bills received from sales, sorting the coins, and counting the coins and bills. Each cash processing unit aggregates sales data by "lot", which is a designation for a grouping of data, where the grouping of data may be according to a particular sales department, having at least one cash register, or according to a particular cash register used for processing sales transactions from at least one sales department. The aggregated sales data is identified by identification codes associated with each lot of data. Each cash processing unit collects sales data and aggregates the sales data, identifying it with a particular code number. This data is then sent to one of the cash processing units that has been designated the master unit.

Abstract: This invention relates to a thermal-fusible tape used to adhere two fabrics together, and used especially to hem slacks.The adhesive tape of the present invention consists of a warp knitted tape, and at least one thermal adhesive thread which longitudinally extends the width of several wales of the warp knitted fabric in each edge portion of said tape and said thread is positioned on one or both surfaces of said warp knitted fabric.
