Abstract: Prodn. of an aromatics-rich fraction for recovery of aromatics from crude coke-oven benzene comprises (a) vaporising the feed in an evapn. column in the presence of H2 under pressure to obtain an overhead vapour stream and a bottoms stream, (b) reacting the vapour stream from (a) with H2 in a high-pressure refining unit to produce the aromatics-rich fraction, (c) distilling the bottoms stream from (a) in a distn. column to obtain a low-boiling fraction and a high-boiling bottoms stream, and (d) condensing the low-boiling fraction from (c) and returning it to the top of the evapn. column as reflux. Depending on the concn. of polymer formers in the feed gasoline, the flow of bottoms from the evapn. column is adjusted to be 6-40% of the feed. The pressure and temp. in the distn. column are adjusted so that the distn. bottoms is practically free of C8- aromatics other than styrene. Also claimed is appts. for carrying out the above process.

Abstract: PURPOSE:To improve the quality and increase the yield, preventing external stress from applying improperly to a resin package in the mold separating process of transfer molding, by making a light transmitting window section facing a semiconductor chip in the resin package a specular surface, making the upper and lower planes excluding the light transmitting window section matte surfaces, and besides making the peripheral side of the package a specular surface with a draft. CONSTITUTION:Concerning a resin package 5, the light-transmitting window section 5a of a package facing the photoelectric receiving plane of a semiconductor chip 1 is made to have a specular surface, and the upper and lower planes of a package excluding the region of the light transmitting window section is made to be matte surfaces 5b. In addition, the peripheral side 5c of the package is made to be a specular surface with a draft (taper angle theta). By doing this, when a die is opened in the mold separating process of transfer molding, external stress is prevented from being improperly applied to the resin package 5 being a molding, and troubles of the resin package 5 such as cracks, warps, or exfoliation of resin from sealed parts are securely prevented. Accordingly, the quality and yield of the products can be improved greatly.

Abstract: Methods for treating surfaces with lipase to provide an enzyme-surface complex and surfaces so treated facilitate oil removal. One such treated surface is a fabric with lipase sorbed onto the surface. A preferred sorbed lipase is isolatable from a Pseudomonas organism or clone. Treated fabrics have substantial hydrolysis activity for oil stains and perhydrolytic activity for oil stains, have altered surface wettability, and retard oil and hydrolysis by-produce redisposition in the presence of aqueous solutions. The sorbed lipase is resistant to removal during fabric laundering and retains substantial hydrolytic activity even with exposure to drying at elevated temperature. The hydrolytic activity of the lipase-fabric complex persists during storage or wear. Hydrolysis by-products are removable during laundering at basic pH or in the presence of surfactant.

Abstract: This relates to a closure cap (44) having an end panel (24) which is equipped with a central button or panel area (50) so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure (44) is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area (50) to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area (50) has been found and such additional stored energy is obtained by utilizing faceted areas or portions (52). <IMAGE>

Abstract: PURPOSE:To restrain the hydraulic pressure of a wheel cylinder from abruptly rising when the supply of hydraulic pressure is changed over from a master cylinder into a hydraulic pressure source upon light braking. CONSTITUTION:A hydraulic pressure control device 44 which is normally set in a first condition such that a master cylinder is communicated with wheel cylinders in calipers 16, 17, is changed over into a second condition such that the servo pressure generated by a servo pressure generating device 46 as a high pressure source is reduced in accordance with a hydraulic pressure in the master cylinder and is then transmitted to the wheel cylinder. Since the hydraulic pressure of the wheel cylinders abruptly increases so that the ability of control for braking force deteriorates upon the above-mentioned change-over, a stroke simulator 56 is provided to avoid abruptly decreasing the hydraulic pressure. That is, the stroke simulator 56 restrains the hydraulic pressure of the master cylinder from abruptly increasing, and accordingly, the hydraulic pressure control device 44 can restrain the hydraulic pressure of the wheel cylinders from abruptly increasing. Further, even in the second condition, a foot pedal 10 can be depressed, thereby it is possible to enhance the ability of control for the brake force and the feeling of braking.

Abstract: A rare-earth bonded magnet is improved in its heat resistance by coating rare-earth magnetic powder with heat resisting addition polymerized thermosetting resin consisting mainly of triazine resin because oxidation of the rare-earth magnetic powder is prevented or retarded by triazine rings formed in the coating film of the thermosetting resin consisting mainly of the triazine resin. The heat resistance of the bonded magnet is further improved by curing the thermosetting resin in a vacuum and by adding organometallic salt in the thermosetting resin as a metallic catalyser since the coating film is formed more firmly.

In the preferred embodiment, memory cells contain one or more chromophoric memory units attached to a support substrate. Each chromophoric memory unit comprises a donor, an acceptor and, at some time during its existence, an active quencher associated with the donor and/or the acceptor. The donor and the acceptor permit non-radiative energy transfer, preferably by F+E,uml o+EE rster energy transfer. To write to the memory cell, the quencher is rendered inactive, preferably by illumination with ultraviolet light. To read, the chromophoric memory units in a read portal are illuminated, and the read illumination is detected. In the preferred embodiment, multiple chromophoric memory units having resolvable read properties are contained within a single read portal. In this way, a multibit word of data may be read from a single diffraction limited read portal. In one aspect of this invention, the read portal is subdivided into multiple write sub-locations, where each sub-location contains chromophoric memory units with acceptors which emit at spectrally resolvable colors. In a further aspect, each sub-location provides variable output based on wavelength, intensity and/or polarization.

Abstract: A control circuit (16) mounted on a faucet (10) operates an ultrasonic transducer (20) that transmits ultrasound into a target region (22) below the outlet (24) of the faucet. The control circuit receives electrical signals from the transducer when the transducer receives echoes from objects within the target region. The control circuit times the echoes to determine the distance of the object causing the echoes, and, if the distance of the object changes between successive measurements, the control circuit operates a valve (12) having an actuator that requires power only to change state so that it keeps the valve open when no power is applied. The circuit is powered by a rechargeable battery (18) that is charged by the action of a generator (31) that is driven by a turbine (34) powered by the flow of water through the faucet.
