  • Patent number: 9133227
    Abstract: A new lignin degradation product, a method for producing the same, and methods for producing a saccharide raw material and a monosaccharide raw material are provided. The method for producing the new lignin degradation product includes: (a first step) mixing 100 parts by mass of a powder, obtained by pulverizing a lignocellulosic raw material and defatting the resulting powder with an organic solvent, with aqueous hydrogen peroxide in an amount of 20 to 400 parts by mass in terms of hydrogen peroxide and heating the mixture for 5 to 120 minutes at a pressure of 0.1 to 1.5 MPa and a temperature of 80 to 200° C. while irradiating the mixture with microwaves; (a second step) separating insoluble matter from the aqueous hydrogen peroxide; (a third step) extracting the insoluble matter with a solvent to produce an extract; and (a fourth step) distilling the solvent away from the extract to yield a solubilized lignin as a residue.

  • Patent number: 8596397
    Abstract: A supporting portion of an inverter bracket is made of cast, and the inverter bracket is attached onto the side member to locate a vehicle rear end portion of the attachment portion to be on the front side in the vehicle, by a prescribed distance from a vehicle front surface portion of the suspension tower. When a force F is exerted from the front side of the vehicle, the side member curves outward in the vehicle width direction between one part to which the suspension tower is coupled and another part to which the inverter bracket is attached. The inverter bracket and inverter are pushed obliquely outward in the vehicle width direction, so that the contact with the master cylinder can be suppressed.

  • Patent number: 6496651
    Abstract: An exposure control method and apparatus for a camera having a two-area divided brightness measurement system. A central light value is determined based on a central area brightness of a photographic scene, and a peripheral light value is determined based on a peripheral area brightness of the scene. After determining by comparison between the central and peripheral light values whether the scene is back-lighted or front-lighted, a correction coefficient specific to back-lighted scenes or that specific to front-lighted scenes is read from a memory. An exposure value suitable for a main subject is calculated according to the following equation: Es=log2{1−(1−&agr;)2LVb−LVa}−log2&agr;+LVa wherein Es represents the exposure value and &agr; represents the correction coefficient.

  • Publication number: 20020021895
    Abstract: A camera has a movable lens barrel that is stowed in a camera body while the camera is inactive, and is protruded from the camera body to a near range focusing position or a far range focusing position by rotating a drive ring in one direction. The movable barrel returns to the stowed position by rotating the drive ring further in the same direction, because of a cam mechanism interconnecting the drive ring with the movable barrel. To rotate the drive ring, a rotational power of a motor in a first direction is transmitted to the drive ring through a clutch mechanism. The clutch mechanism is switched over according to the rotational direction of the motor and transmits a rotational power of the motor in a second direction to another mechanism. A controller controls driving the motor in response to signals entered through manually operated members, including a power switch, a shutter button and a zone selector, with reference to detection signals from a barrel position detector.

  • Patent number: 5600392
    Abstract: A position sensor for detecting a position by comparing a detected level with a threshold level. This operation is performed without being affected by the characteristics intrinsic to the used sensor means or by power supply variations. Furthermore, the operation is not varied even if the sensor means ages. The sensor means is caused to shift from a first operating state to an unoperated state and then to a second operating state according to operation of an object whose position should be detected. The level of the output from the sensor means is compared with a threshold level. Thus, the timing at which the sensor means shifts from the unoperated state to the second operating state is detected. The output level detected when the sensor means is in the first state is stored in a capacitor and divided by resistors to obtain the threshold level.
