An inference processor includes a production rule memory, a meta knowledge generator, a meta knowledge memory, a production system interpreter, and a working memory. The meta knowledge generator obtains production rules satisfying transition conditions between all the combinations of the states of the respective variables in the production rules as a directed-graph matrix. The meta knowledge generator then decomposes the directed-graph matrix into strongly connected components, and obtains, as meta knowledge, 1) variable-conditions of the respective strongly-connected components and 2) production rules satisfying transition conditions between the respective strongly-connected components. The interpreter generally determines an inference path from a given state to another state as a target on the basis of the meta knowledge, and efficiently executes production rules, thereby performing inference processing.

In a folding type telephone apparatus of folding type comprising a first housing and a second housing rotatably connected by a hinge, electric components and printed circuit boards of respective housings are connected by an electrical connecting member of a tape shaped flexible printed circuit which is wound at least two times around a shaft of the hinge. Using the wound electrical connecting member maintains a reliable electrical connection between the housings even after the telephone apparatus has been used for a long time.

In an electromagnetic relay including a pivotable armature (11) and contact springs (17) extending substantially in parallel thereto, the actuator (21) for transmitting the armature (11) movement to the contact springs (17) is coupled to the armature (11) with play. Thereby relative displacements between the actuator (21) and the contact spring (17) and the resultant frictional forces are prevented. When the relay is a bistable relay, the coupling between armature (11) and actuator (21) with play furthermore means that in the central position of the armature (11) no spring forces and no frictional forces caused by the actuator (21) are applied thereto but only the magnetic actuating forces will act on the armature (11). Thereby the risk of the armature (11) inadvertently remaining in its neutral central position is practically eliminated.

The present door for a motor vehicle includes a door glass, a door glass piece and a guide groove. The door glass piece has a substantially crank shape and a forward end sliding portion offset into the vehicle and secured to an end portion of the door glass, the sliding portion of the door glass piece being slidably guided by the guide groove on a door frame aligned to enable opening and closing of the door glass, while the outer surfaces of the door glass and the door frame are substantially flush with each other. According to the present invention the sliding portion of the door glass piece and the door glass are formed such that an angle formed by a center line of the sliding portion and the outer surface of the door glass is less than 180.degree., the outer surface of the vehicle being curved and the door glass conforming to the curvature of the outer surface of a vehicle body, which is continuously formed by the outer surfaces of the door glass and the door frame.

A safety electromagnetic relay includes two pairs of contact sets, each pair including a load-driving contact set and a control contact set, and each contact set including a fixed contact and a movable contact spring. The two load-driving contact sets are normally-open contacts and may be connected in series and included in an external load circuit which requires safe interruption. The contact springs of each of the first and second pairs are ganged by a coupling member which is movable independently of a relay armature. The ganged pairs of contact springs are actuated by the armature in such a manner that when one of the load-driving contact sets should become welded in the closed condition, the other load-driving contact set will still open when the armature moves to the inoperative position, but the control contact set associated with the welded load-driving contact set is prevented from returning to its condition corresponding to the inoperative position of the armature. The status of the control contact set may be utilized to signalize failure of the relay. Specifically, the control contact set may be a normally-closed contact which, when the associates load-driving contact set has welded, is retained in its open condition, thereby preventing recharging of a capacitor that may be required for re-energization of the relay coil.

A reed type relay comprises a frame forming a cavity and having coil terminals. A bobbin assembly containing a coil is mounted in the cavity, this assembly having a flange at each end. A pair of magnetic poles energized by a permanent magnet as well as by the coil is pressed into one of these flanges and the base end of a reed is pressed into the other. This reed is elongated and extends along the bobbin assembly with its tip located between the poles so as to be movable into engagement with each of them.

A zoom lens includes, in order from the object side to the image side, a first lens unit having a positive refracting power and including a reflecting member having a reflecting surface, a second lens unit having a negative refracting power, a rear lens unit group having a positive refracting power as a whole and including at least three lens units, which includes in order from the object side, a third lens unit, a fourth lens unit, and a fifth lens unit. An aperture stop is provided between the second lens unit and the fourth lens unit. During zooming from the wide angle end to the telephoto end, the first lens unit is kept stationary, the second lens unit is located closer to the image side at the telephoto end than at the wide angle end, and the distances between the lens units change. The first lens unit includes, in order from the object side, a negative lens component, the reflecting member, and a rear sub-lens unit including a first positive lens element and a second positive lens element. The second lens unit includes a plurality of lens elements including a negative lens element. The zoom lens satisfies certain conditions.

A zoom lens includes, in order from the object side to the image side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit including a lens. The distance between the first lens unit and the second lens unit is smaller at the telephoto end than at the wide angle end, and the distance between the second lens unit and the third lens unit changes during zooming from the wide angle end to the telephoto end. The first lens unit consists, in order from the object side, of a front sub lens unit having a negative refractive power, an optical path bending member, and a rear sub lens unit having a positive refractive power. The front sub lens unit includes a biconcave single lens, and the rear sub lens unit includes one or two single lenses.
摘要:
A throttle valve controller for an internal combustion engine has a throttle valve driven by a motor. The target opening of the throttle valve is determined based on the operating state of the vehicle or internal combustion engine. A first lower limit is determined beforehand as the minimum target opening, and a second lower limit is set which is smaller than the first lower limit if the determined target opening is smaller than a predetermined opening and/or if the rotation speed of the internal combustion engine is lower than a predetermined speed.
