Abstract: A workflow system includes a sub-workflow define means for defining a sub-workflow which determines a work flow within a section and a sub-workflow interface part disposed at every section, the sub-workflow interface part having a definition of a correspondence of sub-workflow used according to said data. Data is transferred via the sub-workflow interface part disposed at the section units. When the sub-workflow interface part receives data, a sub-workflow corresponding to the received data is activated so that a route can be defined at every section, thereby making it easy to define a route. Therefore, when a change occurs in a section or a route is changed in somewhere of the section, the route may be defined again within that section, and the route can be changed easily. Also, data sequentially flows among the respective sections via the sub-workflow interface part so that a continuity of a work processing among the sections can be maintained.

Abstract: An improvement on a vehicle body is provided which includes bumper brackets joining a bumper reinforcement to ends of side members extending longitudinally of the vehicle body. Each of the bumper brackets has a boss. The boss has formed therein a vertical hole extending vertically of the vehicle body and establishes a connection of the bumper reinforcement and a corresponding one of the side members through a bolt which is fitted within the vertical hole of the boss so as to allow the bumper bracket to rotate inwardly of the vehicle body within a given angular range when the impact acts on the bumper bracket upon occurrence of a font-end collision for ensuring transmission of axial collapsing pressure arising from the impact to the side members.

Abstract: An intermediate joint is provided which joints two cylindrical members to form a side member used in a vehicle body. The intermediate joint includes a front and a rear connecting portion and an intermediate coupling portion coupling the front and rear connecting portions. The intermediate coupling portion is so formed physically as to have a degree of rigidity greater than those of the front and rear connecting portions. This improves the strength or rigidity of the intermediate joint without increasing the overall weight of the side member.

Abstract: An optical recording medium which can provide a wobbling signal at a sufficiently high level even if the track pitch is reduced to enhance the recording density. The recording medium can attain a practically adequate recording-reproducing characteristic such as jitter characteristic. The medium has a wobbling groove that has a depth falling within the range of ë/2.90n to ë/2.15n. Here, ë is the wavelength of a light beam applied to record and reproduce signals and n is the refractive index of the substrate of the optical recording medium. The ratio of the width Wg of the wobbling groove to the track pitch Tp (Wg/Tp) falls within the range of 25.0% to 45.5%.

Abstract: A vehicle body structure provides an increased engine room collapsing stroke to increase energy absorption during a frontal or rear end collision. Force applied to side members is transmitted efficiently to a floor structure by controlled deformation of first, second and third structural portions of a impact redirecting and impact redirecting structure which interconnects the floor and the side members. Occurrence of bending deformation of the inboard end portions of the side members is attenuated to subject the front side member to collapsible compression which increases the engine room collapsible stroke.

Abstract: An optical recording medium in which a high recording density is to be realized as compatibility with respect to a pre-existing optical recording medium is kept. A wobbling groove 5 is formed on a disc substrate 1. The modulation/demodulation system for the wobbling signals recorded on the wobbling groove 5 and that for information signals recorded and/or reproduced on or from the recording track are made to be the same as the modulation/demodulation system for a standardized pre-existing optical recording medium.

Abstract: A vehicle body structure is provided to simplify both positioning and temporary fixing in assembling a dash panel 1 to a reinforcement member 4. The vehicle body structure has engagement parts 21 arranged on both sides of the reinforcement member 4 in a vehicle width direction, for engagement of the member 4 with the dash panel 1. In process of assembling, the dash panel 1 is pinched between the engagement parts 21 through both ends of the panel 1 in the vehicle width direction.

Abstract: A vehicle body structure is provided to both enhance the accuracy in positioning suspension mount bolts 7, 8 and improve the workability in assembling a dash panel 1 to a reinforcement member 4. At the stage of casting the reinforcement member 4, the suspension mount bolts 7, 8 as “insert” elements are fixed to the member 4. Owing to the insert structure of the bolts 7, 8, a distance between the bolts 7, 8 is automatically determined to make it unnecessary to ensure the accuracy of the distance between the bolts 7, 8. The reinforcement member 4 has locating pins 19 integrally formed to engage with locating holes 21 in the dash panel 1. The rear suspension mount bolt 8 is embedded in the locating pin 19 coaxially.

Abstract: A microscope system for observing an image of a sample at desired magnifications includes a first objective lens having an objective side surface which is telecentric, a focusing lens, disposed in an optical path along which optical rays emitted from the first objective lens travel, for focusing the optical rays and forming a sample image and a second objective lens having a magnification factor different from that of the first objective lens. An interchanging member holds the first objective lens and the second objective lens and is used for placing one of the first and second objective lenses in an observational optical path between the sample and the focusing lens. The inequality 0.29<D/fI<0.40 is satisfied, assuming D to be a parfocal length which equals a distance between a surface of the sample and an attachment plane of the objective lens and fI to be a focal length of the focusing lens.

Abstract: The present invention relates to an enzyme-containing granulated substance comprising an enzyme-containing particulate substance and a coating layer which is formed on the particulate substance and comprises (a) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 1 to 100 .mu.m, (b) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 0.01 to 0.8 .mu.m and (c) a binder, and a preparation process thereof.

Abstract: The process for increasing the bulk of a food having a decreased bulk in the present invention comprises applying a means of internal vibration heating such as a microwave oven to a food having a decreased bulk, which has been prepared by subjecting a porous food comprising a cereal flour and water, such as breads, to a treatment such as compression, and has maintained the thus decreased bulk. The food of which the bulk has been increased by such a way has a bulk comparable to the one immediately after baking and exhibits excellent taste and feelings during eating.

Abstract: In a motor vehicle having an engine mounted in an engine room, an exhaust tube system extending from the engine toward a rear end of the vehicle and a fuel tank positioned near the rear end of the vehicle, there is proposed an improved under body structure of the vehicle, by which the fuel tank is effectively cooled during running of the vehicle. The under body structure comprises an under cover positioned below the engine room. The under cover is formed with a longitudinally extending groove whose opening faces downward to contact a relatively low temperature air. A floor panel is formed with a longitudinally extending tunnel whose opening faces downward. The tunnel receives therein the exhaust tube system without contacting the same. A heat insulating plate extends in and along the tunnel in a manner to define in the tunnel an air flow passage which is insulated from the exhaust tube system. The air flow passage has a rear open end directed toward the fuel tank.

Abstract: In a focusing apparatus, a beam of light from a light beam source is imaged on an object to be inspected through one half of the pupil of an imaging optical system and a reflected beam of light from the object to be inspected passes through the other half of the pupil. The object to be inspected and the imaging optical system are moved relative to each other to effect focusing. A light divider divides the reflected beam of light from the object to be inspected into first and second reflected beams of light which are received by first and second light receiving members, respectively. A light intercepting member intercepts the reflected beam of light from the back of the object to be inspected, which is included in the second reflected beam of light. A controller moves the object to be inspected and the imaging optical system relative to each other on the basis of the outputs of the first and second light receiving members.

Abstract: There is disclosed a microscope provided with a parallel ray optical system, for forming parallel light rays, between the objective lens and the eyepiece lens. A lens barrel supporting the parallel ray optical system is axially extended or retracted with respect to the objective lens, such as by mutual engagement of a ratchet and a claw member, thereby varying the optical path length of the parallel light rays and thus adjusting the height of the eyepiece lens.
