Title: Crankshaft angular position detecting apparatus
Inventor: DAVIS MICHAEL ALLAN
IPC: F02P7/067
Filed: 1991-05-23
Granted: 1996-03-26
Abstract: A crankshaft angular position detecting apparatus for detecting the angular position of the crankshaft of an internal combustion engine.  The crankshaft drives a timing wheel which has a plurality of circumferentially spaced slots located along its outer periphery.  Two angularly spaced sensors are located adjacent the slots.  The sensors develop voltage pulses as the slots move past the sensors.  Two phase-displaced pulse trains are developed, one by each sensor, as the wheel rotates.  The pattern of slots and the angular spacing of the sensors is such that a varying number of pulses of one pulse train occurs between consecutively occurring pulses of the other pulse train.  The varying number of pulses provide different patterns and each pattern is indicative of a crankshaft position.  The timing wheel is secured to the engine crankshaft and is located inside of the engine.

Title: Transport and storage container with sheet-metal floor
Inventor: DECROIX CLAUDE
IPC: B65D19/10
Filed: 1992-05-22
Granted: 1996-02-13
Abstract: A transport and storage container has an annular and erect outer wall constituted as a grid of welded-together verti-cal and horizontal bars and having a lower edge provided with a lower-edge bar and an upper edge provided with an upper-edge bar, a normally horizontal and generally rectangular sheet-metal floor plate having an inwardly open C-section outer rim engaged over the lower-edge bar, and a flexible inner vessel enclosed by the outer wall and resting on the floor plate.  The floor plate has four sides including two opposite sides formed with the C-section outer rim.  In addition another of the sides is also formed with the C-section rim and a fourth side is free of the C-section rim and the fourth side of the floor plate is formed with outwardly projecting tabs that engage over the lower-edge bar.  This makes assembling the container a simple matter of sliding the plate parallel to its opposite sides underneath the outer wall with the rims engaging over corresponding sections of the lower-edge bar until the tabs engage over and past at least one further section of the lower-edge bar.  The tabs can be bent down over the fourth side to lock the assembly permanently together.

Title: Polyimide multilayer interconnection board and method of making the same
Inventor: KIMBARA KOHJI
IPC: H01L23/538
Filed: 1992-11-17
Granted: 1997-12-23
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.

Abstract: A variable message display sign having a power source and comprises a plurality of character displays each having signal elements organized in distinct sets, each said signal element having an on state and an off state. A controller located remotely from the character displays produces an address signal containing character address data for identifying an addressed character display, a set signal containing set address data for identifying an addressed set of signal elements and a data signal containing display data corresponding to desired on/off states for each signal element in the addressed set. A logic circuit associated with each character display has a unique character address therefor, each logic circuit located proximately to a respective one of the character displays and having a memory operative in response to an address signal containing character address data corresponding to the unique character address of the logic circuit to receive and store the display data according to the set address data for an addressed set of signal elements. The logic circuit is operative to switch the signal elements of its associated character display to a desired pattern of on/off states according to the display data stored in the memory thereby to display a desired character. A data bus interconnects the controller and the logic circuits whereby the character address data, the set address data and the display data are communicated to the logic circuits.
