Patent number: 8485585Abstract: A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).Type: GrantFiled: June 24, 2010Date of Patent: July 16, 2013Assignee: Nifco Inc.Inventors: Katsuhiko Taniguchi, Katsuhito Kurachi

Patent number: 6467130Abstract: A damping structure is formed of a base including at least one projecting portion having a shaft or a hole, and a first engaging portion; a rotating member including a first wall portion having the other of the hole or the shaft engaging the shaft or hole, a second wall portion facing the first wall portion to receive the projection therebetween so that when the first wall portion is supported by the projecting portion, a space is formed between the projecting portion and the second wall portion, and a second engaging portion; and a damper disposed in the space. The damper includes an inner shaft having a third engaging portion engaging the first or second engaging portion, and an outer shaft rotatably situated around the inner shaft to generate a damping force against a rotation of the inner shaft. The outer shaft has a fourth engaging portion engaging the first or second engaging portion to thereby provide a damping force to the rotating member.Type: GrantFiled: July 31, 2001Date of Patent: October 22, 2002Assignee: Nifco Inc.Inventors: Katsuhito Kurachi, Akihiko Hirose

Patent number: 6388690Abstract: Every time after a cyan ink and a magenta ink are transferred to form respective color dots of a line with a length L2 in a sub-scanning direction, an ribbon cassette RC is returned to a start position of the transference of the cyan and magenta inks and moved by half of a pitch of a print dot of the cyan and magenta inks in the sub-scanning direction by a carriage moving mechanism CH. Subsequently, an yellow ink is transferred to form yellow color dots of a first column. Every time after the ribbon cassette RC is moved by a pitch P1 each in the sub-scanning direction, the yellow ink is transferred to form dots of one column until dots of all columns in the length L2 of a line are formed.Type: GrantFiled: November 13, 2000Date of Patent: May 14, 2002Assignee: Brother Kogyo Kabushiki KogyoInventor: Katsuhito Kurachi

Patent number: 6322114Abstract: A latch unit of the invention includes a casing having a holding chamber for holding a striker and a side chamber situated adjacent to the holding chamber, and a responding member housed in the side chamber. The holding chamber and the side chamber are partitioned by an elastic member projecting toward an introduction opening of the holding chamber for introducing the striker to be attached to the latch unit. The electric member is provided with an engaging projection for engaging the striker as the striker is inserted into the holding chamber. The side chamber is provided with an urging device for urging the responding member toward a base portion of the elastic member. An urging force of the urging device is set such that when an inertia force is applied to release an engagement of the elastic member and the striker to thereby extract the striker from the holding chamber, the responding member is allowed to move to a position for preventing the elastic member from being bent toward the side chamber.Type: GrantFiled: September 2, 1999Date of Patent: November 27, 2001Assignee: Nifco Inc.Inventors: Katsuhito Kurachi, Naohiro Shimajiri

Patent number: 6250708Abstract: A holding device of a shaft, i.e. a shaft for a sun visor, includes a base and a holder. The base includes a base main portion and anchors. The holder has a holder main portion and a supporting leg. The supporting leg is provided with lock portions on an outer periphery thereof. The lock portions are engaged with a back surface of the base main portion when they are inserted into the inserting hole, and the supporting leg is rotated from an inserted position. Thus, the holding device for the sun visor can be easily attached to a vehicle body.Type: GrantFiled: April 11, 2000Date of Patent: June 26, 2001Assignee: Nifco Inc.Inventor: Katsuhito Kurachi

Patent number: 6222572Abstract: The energy amount supplied to each dot forming a pixel is determined to 8 levels. In a dot pattern of the gradation level 1, the energy amount level 1 is provided to a dot 35 of the pixel 31. In the gradation level 2, the energy level 1 is provided to the dots 35 and 36. In the gradation level 3, the energy level 1 is provided to the dots 35 to 37. Similarly, the energy levels 1 to 8 are provided successively to the dots 35 to 38 to form dot patterns of the gradation levels 3 to 31. In the gradation level 32, the energy level 8 is provided to the dots 35 to 38.Type: GrantFiled: September 21, 1998Date of Patent: April 24, 2001Assignee: Brother Kogyo Kabushiki KaishaInventor: Katsuhito Kurachi

Patent number: 5961227Abstract: The number of pulses N corresponding to the gradation level of a print dot is read out from a table and stored in a counter 63 (S1). The first pulse is applied to the heating elements for the duration T.sub.1 (S4) and is stopped for the duration T.sub.off (S6). The number of pulses N is read out and restored in the counter after the subtraction of 1 therefrom (S7). The second pulse is applied for the duration T.sub.2 (S9) and then interrupted for the duration T.sub.off (S11). The number of pulses N is read out and, after 1 subtracted therefrom, is restored (S12). If the number of pulses N read out is not zero, the step for the application of pulses for the duration T.sub.2 (S9) and subsequent steps are repeated. If the number of pulses N is zero, the application of pulses is terminated (S13).Type: GrantFiled: August 27, 1998Date of Patent: October 5, 1999Assignee: Brother Kogyo Kabushiki KaishaInventor: Katsuhito Kurachi

Patent number: 5775748Abstract: A latch device in which joggling of a latch main body is prevented and smooth movement of the latch main body is realized. When the latch main body is pushed-in from a first position of an insertion direction of the latch main body, holding of the first position is cancelled. Due to a spring, a stopper moves in a guide hole and abuts an end of the guide hole and the latch main body reaches a second position at a side opposite an insertion side. If the latch main body is pushed-in from the second position, the latch main body returns to the first position. When the latch main body is pushed-in to the first position and moves, an abutting portion extending from the stopper to a latch main body insertion side slides along an inner surface of a case wall, in a direction in which the stopper fits into the guide hole, along a side edge of the guide hole at a region at which the abutting portion misses the guide hole.Type: GrantFiled: January 11, 1996Date of Patent: July 7, 1998Assignee: Nifco Inc.Inventor: Katsuhito Kurachi

Patent number: 5401067Abstract: A latch device includes a latch body provided in a housing so as to be movable in an inserted direction in which the latch body is inserted into the housing, and in a withdrawn direction in which the latch body is withdrawn from the housing, and being continuously urged in the withdrawn direction. Further, circulatory cam grooves are also provided in the housing, and a supporting member is inserted into the circulatory cam grooves and circulates and moves in the circulatory cam grooves so as to hold the latch body at an inserted state position and a withdrawn state position.Type: GrantFiled: June 8, 1993Date of Patent: March 28, 1995Assignee: Nifco, Inc.Inventors: Mutsuo Kurosaki, Katsuhito Kurachi
