  • Patent number: 10434133
    Abstract: An oligopeptide having a good anti-inflammation effect on microglia has been found, and based on this finding, a composition to be used for suppressing the inflammation of microglia is provided. Inflammation suppression action of a dipeptide has been comprehensively analyzed using the proinflammatory cytokine production of microglia as an indicator. As a result, it has been revealed that an oligopeptide including the sequence LH, DV or MH has a good inflammation suppression effect. The composition containing any of these oligopeptides can provide a composition having the effect of suppressing the excessive inflammatory action of microglia.

  • Publication number: 20160178036
    Abstract: A hydraulic pressing unit for pressing an input disc in an axial direction includes a first hydraulic pressure chamber and a second hydraulic pressure chamber, a primary piston facing the first hydraulic pressure chamber and a secondary piston facing the second hydraulic pressure chamber, and oil holes configured to supply oil into the first hydraulic pressure chamber are formed in an input shaft, while oil paths configured to supply oil into the second hydraulic pressure chamber are formed in the secondary piston. Consequently, a separate oil hole configured to supply oil into the second hydraulic pressure chamber is not formed in the input shaft. Thus, it is possible to mitigate the cost and labor hours involved in fabrication of the input shaft. Two oil holes spaced apart from each other in an axial direction do not exist in the input shaft.

  • Patent number: 8998498
    Abstract: A tapered roller bearing improves durability during a state of insufficient lubrication by sufficiently lengthening the time until rotation becomes impossible due to seizure. Oil retaining concave sections, recessed outward in the radial direction, are formed in portions on the inner circumferential surface of a large-diameter rim section of the retainer whose phase in the circumferential direction coincides with the pockets. A portion of the bottom surface of each of the oil retaining concave sections, open to the inside surface of the pocket, face a concave section formed in an end surface on the large-diameter side of tapered roller that is held inside the pocket. When lubrication becomes insufficient, oil remaining in the concave sections is effectively used for lubricating areas of sliding contact between the end surfaces on the large-diameter side and the inside surface in the axial direction of a large-diameter side flange section.

  • Patent number: 5676479
    Abstract: A continuous form printer is provided with two rotary encoders, corresponding to different paper feed intervals, and mounted coaxially on a drive shaft. The drive shaft drives a tractor for feeding the paper. The rotary encoders are read by photo-interruptor sensors, and the sensor signals are selected by a selector. The selector is able to select either one of the sensor signals generated by the encoders, or a signal formed by performing an AND operation on the two sensor signals. A controller controls a motor driving the drive shaft according to the selected signal, the selected signal corresponding to a chosen feeding interval. The controller is further able to precisely adjust the leading edge of the paper to a predetermined position based on the selected sensor signal, a known paper length, and a paper top sensor.

  • Patent number: 5649274
    Abstract: An electrophotographic printer is capable of using a plurality of types of continuous form recording media having different page lengths, respectively. In the printer, a photoconductive member is charged and exposed to light carrying image data to form a latent image. In operation, one of the plurality of types of recording media is selected, and a portion of the photoconductive member corresponding to a page of the selected one of the plurality of types of recording media is exposed to light. In another embodiment, a laser beam printer utilizes a continuous-form recording sheet, wherein two control members are provided for, respectively, controlling the recording sheet so as to be discharged from the printing device after a printing operation, and for controlling the recording sheet so as to be located at a position from which a printing operation is restarted. Thus, recording sheets are not wasted when printer output is started.
