A reclining mechanism for a vehicle seat includes first and second attachment members coupled with each other at their outer peripheries and connected by a hinge pin, a slide pawl slidably mounted within one of the attachment members, and a cam element mounted on the hinge pin in a space between the attachment members. The cam element is engaged with the slide pawl to maintain engagement with the ratchet portion of the attachment member when the hinge pin is retained in a torsion spring load position. This construction permits relative rotation of the attachment members for adjustment of an inclined angle of a backrest. In the reclining mechanism, a thrust member is coupled with one of the attachment members and welded to a frame structure of the back rest allowing the device to be assembled as a unit.

A spring force of a thrust spring can be determined independently of a spring force of a locking spring, reducing an operating load of an unlocking operation. A locking device includes a locking mechanism provided on one of two members to be engaged with each other, and a striker provided on the other of the two members. The locking mechanism includes a base plate, a hook, a pawl, a cam, a locking spring, a thrust spring and a canceling plate. The base plate has a recess that is capable of receiving the striker. The hook, when rotated relative to the base plate, is capable of forming a locked condition in which the striker is held between the hook and the recess of the base plate or an unlocked condition in which the hook is spaced away from the striker. The pawl is capable of rotating relative to the base plate and maintaining the hook in the locked condition. The cam is capable of further pressing the hook in the locked condition toward a locking direction. The locking spring is capable of biasing the hook and the pawl such that the hook and the pawl are stabilized in the locked condition or the unlocked condition. The thrust spring is capable of biasing the cam in a direction to press the hook. The canceling plate is rotatably supported via a shaft of the hook and is coaxially rotatable with the hook. The canceling plate has a movable range in which the canceling plate can rotate relative to the hook and has a contacting portion that is capable of contacting the striker within the movable range when the hook is in the locked condition.

A microcapsule-containing water-base coating formulation comprises as essential components (a) microcapsules making use of a synthetic resin as a wall-forming material and (b) a reaction product obtained by polymerizing at least one water-soluble vinyl monomer (B) in the presence of a high polymer latex (A) having a glass transition point of 60.degree. C. or lower. The latex (A) and vinyl monomer (B) are used at a solid weight ratio of 3:97-90:10. The water-base coating formulation can provide a microcapsule-coated layer having significantly-improved pressure resistance and frictional stability without need for a stilt. The water-base coating formulation can be applied at a high speed, thereby making a significant improvement to the productivity of carbonless copying and/or recording paper.

This invention relates to a temperature control indicator unit comprising a substrate having supported thereon (a) microcapsules enclosing a hydrophobic organic compound possessing an arbitrarily selected melting point, (b) a methine dye and (c) an oxidizing material. More particularly, a unit made by combining an irreversibly color-developing methine dye and an oxidizing material with microcapsules enclosing a hydrophobic organic compound possessing a predetermined melting point and supporting them on a substrate is used for temperature control purposes. A suitable measure is taken, preferably at or below the desired control temperature, to break at least a part of the microcapsules of the unit and thereby produce fissures or the like in the microcapsule membrane. Then, the unit is stored or transported together with an article to be placed under temperature control. As a result, if the article is exposed to temperatures exceeding the desired control temperature, the non-volatile organic compound present in the broken microcapsules melts and diffuses out. This brings the methine dye into contact with the oxidizing material present in proximity thereto and causes an irreversible color development of the methine dye. Thus, the occurrence of abnormal temperature control conditions can be detected by observing such color development.

Disclosed is a color-developer for pressure-sensitive recording sheets, comprising a co-condensate of a reaction intermediate of a p-substituted phenol and a trifunctional or higher phenol, or a polyvalent metal salt of said co-condensate, said reaction intermediate being obtained by the reaction of said p-substituted phenol under acidic conditions with formaldehyde or a substance capable of generating formaldehyde.

A locking device includes a locking mechanism and a striker. A hook of the locking mechanism, when rotated, is capable of forming a locked condition in which the striker is held between the hook and a recess of a base plate. A pawl is capable of rotating to a position in which the pawl can engage the hook and maintaining the hook in the locked condition. A locking spring is capable of biasing the hook and the pawl such that the hook and the pawl are stabilized in the locked condition or the unlocked condition. A thrust member is capable of rotating to a thrusting position in which the thrust member can press the hook in the locked condition toward a locking direction via a cam surface formed therein. A thrust spring is capable of biasing the thrust member toward the thrusting position. A through hole that is formed in the thrust member forms a deformation promoting portion. The deformation promoting portion is capable of deforming the thrust member when a load having a predetermined value or more is exerted on the thrust member side from the hook side.

A reclining mechanism for a vehicle seat composed of a first arm member for attachment to a frame structure of a seat cushion or a back rest of the vehicle seat; a second arm member for attachment to a frame structure of the other of the back rest or the seat cushion, the second arm member being connected with the first arm member by means of a hinge pin for relative rotation about the hinge pin and having a pair of diametrically opposed semi-circular ratchet portions concentric with the hinge pin; a pair of diametrically opposed slide pawls slidably coupled with the first arm member in a radial direction with respect to the hinge pin to be moved toward and away from the ratchet portions of the second arm member; and a cam element slidably coupled with the first arm member in a lateral direction perpendicular to the slide pawls and disposed between the slide pawls, the cam element being operatively connected with the hinge pin to be moved by rotation of the hinge pin in the lateral direction for engaging the slide pawls with the ratchet portions of the second arm member and for disengaging the slide pawls from the ratchet portions of the second arm member, wherein the hinge pin is loaded by a torsion spring assembled thereon to bias the cam element in the lateral direction for maintaining the slide pawls in engagement with the ratchet portions of the second arm member.
摘要:
A program is selected from a plurality of programs in an MPEG transport stream for recording on a record carrier. The presence of a program clock reference (PCR) value in a packet in the stream is detected. The packet identifier for the packet is retrieved and stored. Clock reference signals of subsequent packets with a packet identifier equal to the stored packet identifier, are retrieved. The program clock references are used to synchronize a clock counter. Each recorded packet is time stamped according to the clock counter. If clock reference signal is not received within 100 ms, then a packet with a PCR value with a different packet identifier is retrieved and the stored packet identified is replaced by the different packet identifier.
