| 20110158680 | OPENING-AND-CLOSING MECHANISM AND IMAGE FORMING APPARATUS - An aspect of the invention is an opening-and-closing mechanism including: an opening-and-closing member that open-and-closes an body; a holding member rotatably coupled to the body; a sliding member disposed slidable to the holding member along a longitudinal-direction of the holding member, whose end portion is coupled to the opening-and-closing member, and sliding to the holding member in accompaniment with rotation of the opening-and-closing member; a braking member of an elastic material whose coefficient of friction with one of the sliding member or the holding member is larger than that between the other of the sliding member or the holding member and the one, the braking member sliding to the one in accompaniment with the sliding member sliding to the holding member to generate a braking-force by a frictional-force; and a pressing member disposed on the other, the braking member being mounted thereat, pressing the braking member against the one. | 06-30-2011 |

| 20120070211 | DOCUMENT TRANSPORTING DEVICE AND IMAGE FORMING APPARATUS - A document transporting device includes: a document-accommodating-section; a transporting-mechanism; a feeding-member that feeds a document to the transporting-mechanism by rotating; a rotation-shaft that is driven to rotate and rotatably supports the feeding-member; an engaged-portion formed at an end portion of the feeding-member; a transmitting member that, by moving in a rotation-shaft-axial-direction, can be located at a transmitting-position where rotation of the rotation-shaft is transmitted to the feeding-member by an engaging-portion of the transmitting member being engaged with the engaged-portion, and at a releasing-position where engagement therebetween is released; a moving member provided on the rotation-shaft, that, upon relative rotating of the rotation-shaft and the transmitting member, moves the transmitting member to the transmitting-position and transmits the rotation of the rotation-shaft to the transmitting member; and a resistor that contacts with an outer peripheral surface of the transmitting member and provides a resistance in a rotational-direction to the transmitting member. | 03-22-2012 |

| 20110166520 | INJECTION NEEDLE AND DRUG INJECTION DEVICE - A needle tip of a needle tube stuck in the skin is caused to be reliably positioned in the skin upper layer part and the injected drug is caused not to leak to the outside of the body. | 07-07-2011 |
| 20110275994 | INJECTION NEEDLE ASSEMBLY AND DRUG INJECTION DEVICE - To securely position a needle tip and a blade face of a needle tube inserted into the skin in a predetermined site of a living body, such as the upper layer of skin, an injection needle assembly includes a needle tube having a needle tip capable of puncturing a living body, a hub holding the needle tube, a stabilizer, and a guide portion. The stabilizer is formed in a tubular shape surrounding the circumference of the needle tube, and an end face is pressed against the skin, and thereby a raised portion of the skin is formed in a tube hole. The guide portion is arranged on the stabilizer, and is adapted to recognize a press-in distance y of the stabilizer to the skin. | 11-10-2011 |
| 20120046615 | SYRINGE NEEDLE ASSEMBLY AND MEDICAMENT INJECTION DEVICE - An injection needle assembly includes a needle tube | 02-23-2012 |

| 20100316394 | Optical receiver and jitter tolerance control method - An optical receiver includes an optical device that receives input light and converts the input light to an electric signal; an equivalent part that carries out waveform shaping on the electric signal; an amplifier that amplifies the electric signal; a discrimination part that discriminates data of the electric signal; an input optical power detecting part that detects input optical power of the input light; and a control part that makes an error rate in the electric signal with respect to the input optical power worse when the input optical power detected by the input optical power detecting part is equal to or less than a value corresponding to minimum receiver sensitivity. | 12-16-2010 |
