Abstract: A connector to be mounted on a substrate includes a plurality of contacts each having a contact portion adapted to contact a mating object and a connection portion of a surface mounting type to be connected to a substrate, and a housing having inserting holes for arranging and holding the contacts therein and a fitting portion to be fitted with the mating object. The connection portions are arranged substantially in parallel with the bottom surface of the housing. The bottom surface of the housing is provided with protrusions respectively for the contacts for positioning the connection portions in directions of their heights and confirming positions of the connection portions in the longitudinal direction by bringing the individual connection portions into contact with the protrusions, respectively. The connector thus constructed is free from failed electrical connection and easily and visually confirmed whether the contacts are situated in correct positions without using jigs or the like.

Abstract: A connector includes a housing and a plurality of contacts, and the bottom portion of the housing has a holding bar for holding the contacts. In a region of the bottom portion of the housing corresponding to tips of all the contacts extending from the holding bar upwardly and toward the interior of the housing, a rectangular recess is provided, and a contact buckling-preventing plate is provided in the recess, which includes an upper surface portion formed with through-holes at locations corresponding to contact portions of the contacts, partition walls forming defined spaces for accommodating the contacts in cooperation with the upper surface portion, and jointing ends to be connected to both lateral inner ends of the recess on the side of the holding bar to permit a pivotal movement of the plate. In this manner, the connector can realize an even more reduced overall height and prevent the buckling of contacts upon extraordinary insertion and removal of a card-shaped connecting object.

A method of producing a chlorogenic acid composition, which comprises allowing a water-soluble composition extracted from raw coffee beans or roasted coffee beans to be adsorbed to a column filled with an adsorbent and then eluting a chlorogenic acid composition by passing a 0.5 to 20 vol % ethanol aqueous solution.

Abstract: A connector for a jack includes four contacts of first, second, third and fourth contacts each having a contact portion and a connection portion, and a housing, to exchange signals and to ascertain whether a plug connector has been inserted into the connector. The third contact substantially U-shaped in cross-section includes a contact piece having a first contact part adapted to contact the plug connector, and a spring piece having an elasticity facing to the contact piece and provided by forming a U-shaped slit in a part of the third contact at a location opposite to the contact piece. When the plug connector is inserted into the connector, the plug connector pushes the first contact part of the contact piece to cause the contact piece to be displaced to the spring piece so that the contact piece pushes the spring piece to cause the spring piece to be displaced toward the housing and at the same time the spring piece pushes the contact piece with each other with the aid of its elasticity.

Abstract: The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.

Abstract: A card connector includes contacts adapted to contact contacts of two memory cards, a housing having inserting openings for inserting the memory cards and arranging and holding the contacts therein, and a shell covering the housing. The housing includes two side walls, a rear wall, and a lower wall contiguous with these side and rear walls to form the inserting openings for the memory cards by these two side walls, rear wall and lower wall, and is provided with a pivotally movable plate to form, by its pivotal movement, the one inserting opening for inserting either of the cards and simultaneously to prevent the other card from being inserted. The card connector enables stable connection by merely inserting two different cards having equal lengths in the inserting direction and different widths and thicknesses into the connector.

Abstract: A card connector into and from which a memory card is detachably inserted and removed, includes contacts adapted to contact connection portions of the memory card, and a housing for arranging and holding the contacts. Metal plates made of a metal are installed in the housing so as to extend onto both sides in the width direction of the housing. The metal plates are integrally provided with connection portions to be connected to a substrate. A tray made of a metal is provided for loading a plurality of memory cards therein, and either of both ends of the tray in its width direction is bent substantially into an L-shape, which bent portion slidably engages the metal plate. The connector achieves a reduced overall height such as less than 2.0 mm and is also superior in safety.

Abstract: A heavy oil reforming method which reforms a heavy oil to give a fuel suitable for a gas turbine, eliminates sulfur and vanadium, i.e., harmful components, from a heavy oil, and enables almost all the hydrocarbons in the heavy oil to be used in gas turbine combustion; an apparatus therefor; and a gas turbine power generation system using the reformed heavy oil as fuel is disclosed. The method includes reacting a heavy oil with supercritical water and then with a scavenger for sulfur and vanadium to eliminate sulfur and vanadium from the heavy oil.

Abstract: In the disk array system, in the basic chassis, HDD modules are installed from a front surface in a front part of a backboard, and duplex CTL modules are installed up and down from a rear surface in a rear part, and duplex power source modules containing fans are installed in the left and right sides thereof. By the operation of the fans, in the rear part, the cooling air flows separately into each CTL module and into each power source module, and the cooling air having passed through the area of the duct by a block in the CTL module is drawn by the fans in the power source module through a ventilation hole and is then exhausted outside. The cooling air flow path to the plurality of ICs is divided by the block. The rotation speed of the fans is controlled by using a temperature sensor.

Abstract: The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercritical water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.

Abstract: A process for producing a tea extract containing non-polymer catechins, which includes immersing unfermented tea leaves in ethanol or an ethanol-water solution having an ethanol concentration of from 85 to 99.5 vol % to obtain unfermented tea leaves having a percentage catechin residue of at least 80 wt % based on a catechin content of the unfermented tea leaves before the immersion in the ethanol or ethanol-water solution, and then extracting the unfermented tea leaves with warm water or hot water. The highly-efficient extraction of non-polymer catechins makes it possible to obtain a tea extract, which has an improved taste and does not produce sediment when added to beverages.
