  • Publication number: 20140234936
    Abstract: In the present disclosure, after a volatile organic acid is added as a catalyst to a slurry and the hydrolytic saccharification reaction of hemicellulose is performed, the volatile organic acid (including one added to the slurry and one produced as a by-product) contained in a C5 saccharified solution can be easily recovered by adding a small amount of sulfuric acid to the C5 saccharified solution and subjecting the C5 saccharified solution to air stripping treatment. The efficiency of hydrolytic saccharification of hemicellulose into C5 sugars using a volatile organic acid can also be continuously improved by adding the recovered volatile organic acid as a catalyst to another slurry of cellulosic biomass.

  • Patent number: 8740264
    Abstract: A vehicle door lock device includes an active lever configured to bring an open link into a locked or unlocked state, and a child safety lock mechanism configured to enable pushing force transfer from an inside open lever to the open link in an unset state. Under a condition where the door is in an opened state, the active lever is situated at an unlocked position, and an intermediate member of the child safety lock mechanism is situated at an unset position, when a door opening operation of an inside door handle and an operation of a child safety protector lever for the intermediate member to move from the unset position to a set position are sequentially performed, a pushing portion of the intermediate member is engaged with an engagement portion of the active lever so that the active lever moves from the unlocked position to a locked position.

  • Publication number: 20140047874
    Abstract: A child protector mechanism includes a base member, a first lever, a second lever, a bush arranged between the first lever and the second lever, a child protector lever for moving the bush to an unset position or a set position, and a position retaining means provided between the first lever and the bush. The bush is retained at each of the unset position and the set position by the position retaining means provided between the first lever and the bush. Therefore, when assembling the bush and the first lever to the base member, the bush is retained at a predetermined position (for example, unset position) with respect to the first lever so that the bush does not move. Thus, the easiness of assembly of the bush and the first lever and the easiness of assembly of the child protector lever are excellent.

  • Publication number: 20140028036
    Abstract: Provided is a position holding device for a rotating lever, which includes a rotating lever and a torsion spring, and is capable of elastically holding the rotating lever at the two positions including a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part and facing each other across an engagement portion of the rotating lever. The first arm part includes a mountain portion formed at an intermediate portion thereof. The second arm part includes an urging portion. As a result, an urging force generated by the urging portion can be applied to the rotating lever as a braking force against an urging force generated by the mountain portion. Consequently, it is possible to reduce an abutment noise generated when the rotating lever abuts against a stopper member.

  • Publication number: 20120313385
    Abstract: Provided is an automotive door latch device, including: a latch pushed to rotate by a striker; a latch return spring for biasing the latch toward a return position thereof; a pawl engageable with the latch to inhibit the latch to pivot in a door opening direction (return position); and a pawl return spring for biasing the pawl toward a return position thereof. A housing part of a body, which houses the latch and the pawl, is opened downward at a position below the pawl on one side of the body. The pawl return spring is assembled to a spring mounting part formed on another side of the body at a position spaced downward from a rotational support part of the pawl, and includes a pawl-side end part that engages with the pawl through a through hole provided in the body. Thus, dust or the like entering the housing part of the body, which houses the latch and the pawl, can be discharged out of the body with higher efficiency.
