Patent CA-2079754-A1 (CA)
Inventor: SLICKER JAMES M
IPC: B60K23/02
Filed: 1992-10-02
Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor and a transmission input speed sensor and develops a clutch actuation signal controlling a clutch actuator between from disengaged to fully engaged. The clutch actuator at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach a reference speed employing an approximate inverse model of this oscillatory response.          In a launch mode, corresponding to normal start of the vehicle, the reference speed is the measured engine speed.          In a creep mode, corresponding to slow speed creeping of the vehicle, the reference speed is a creep speed reference based on the throttle setting and the engine speed. The two modes are selected based upon the throttle setting. The automatic clutch controller preferably includes an integral error function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a prefilter and a compensator constructed to reduce the need for detailed particularization for individual vehicles or vehicle models.

Patent CA-2083077-A1 (CA)
Inventor: KIMBARA KOHJI
IPC: H01L23/538
Filed: 1992-11-17
Abstract: According to the present invention, there is provided a method of making a polyimide multilayer interconnection board having multiple line layers using a polyimide resin for interlayer insulation on a ceramic substrate or a hard organic substrate, in which, in order to electrically connect one block comprising a laminate having a plurality of line layers to another block of the same arrangement, a metallic bump provided at each block is utilized.  At least one of the pair of metallic bumps, which is connected to each other, comprises a solder.  With the two subassemblies forced against each other, the metallic bump made of the solder is heated up to a temperature enough to melt so that the contacting metallic bumps are connected.  In consequence, a through hole adapted to electrically connect the plurality of blocks becomes unnecessary with the result that the production process is simplified and the time required for it is shortened.

Title: Self erecting portable structure and method therefor
Inventor: GARTIN JACK H
IPC: E04H15/40
Filed: 1992-11-30
Abstract: ABSTRACT      A self erecting portable structure is provided which comprises a single rod or wire joined at its ends by a single connector to form an of endless loop structure comprising at least a first lower loop means and a second upper loop means.          A first fabric means having sleeves at each end is provided in a transverse position such that one portion of the first lower loop means and another portion of the second upper loop means is contained in the sleeve at one end of the first fabric means and such that still another portion of the first lower loop means and of the second upper loop means is contained in the sleeve at the other end of the first fabric means. Elastic tension in the first lower loop means and the second upper loop means pulls the first fabric means taut to form a first lower surface of the structure. A second fabric means  having  sleeves  at  each  end  is  provided  in  a longitudinal position such that one portion of the second upper loop means is contained in the sleeve at one end of the second fabric means and such that another portion of the second upper loop means is contained in the sleeve at the other end of the fabric means. Elastic tension in the second upper loop means pulls the second fabric means taut to form a second upper surface of the structure which is separate from the first lower surface so that an interior structure space is created which can be accessed from all sides of  the structure. Further, the interior structure space is created without the need for external stakes,  pegs or ropes and without the need for internal poles or supports.    Because of  the elastic nature and the endless loop structure formed by the single rod or wire joined at its ends by a single connector, the first lower loop means and the second upper loop means together with the accompanying fabric means can be readily folded in upon themselves to form four loops of smaller diameter. The elastic energy of this folded structure is easily contained by strap and a zippered cover so that the complete structure is portable and easily stored in a closet or the trunk of an automobile. When the folded structure is removed from its storage cover,  the stored elastic energy allows the structure to "pop up" into its final configuration with no further action from the user, thus providing the self erecting feature which makes the structure so convenient to use.    The present invention can be employed in a wide variety of forms by changing the size and shape of the first and the second fabric means and of their sleeves. Thus, the present invention can take the form of a completely closed camping tent with screened doors and windows as required or the form of an open ended sun screen or beach shelter which can be accessed from the front and sides without sacrificing the features of being self erecting and highly portable.
