Patent CA-2109289-A1 (CA)
Inventor: PETERSON RUDOLPH A JR
IPC: B60W30/18
Filed: 1993-10-26
Abstract: An interlock circuit for a vehicle such as a lawn and garden tractor with a switch-controlled PTO and obstacle sensor.  The circuit provides engine shutdown and PTO disconnect if a sensor switch is tripped while the vehicle is in reverse.  Engine recovery is allowed with the sensor switch tripped if the transmission is shifted out of reverse.  If the tactile sensor fails to reset when the vehicle moves forward, the circuit prevents PTO reactivation.  Once the sensor resets, the PTO can only be turned on by cycling the PTO switch.

Patent CA-2126292-A1 (CA)
Title: Method of manufacturing and inspecting semiconductor devices
Inventor: TANAKA NOBUHISA
IPC: H01L21/22
Filed: 1994-06-20
Abstract: ABSTRACT OF THE DISCLOSURE              Closed tube methods have been employed to diffuse impurities selectively in a groups m - v semiconductor wafer. The closed tube methods are convenient for preventing the element of group V from dissociating out of the wafer surface by pressurizing the vapor pressure of the element of group V. Open tube methods failed in diffusing impurities without defects due to the fluctuation of the vapor pressure of the element of group V.          Both methods have relied upon the vapor phase diffusion using a gas containing impurities. This invention adopts an open tube method of diffusing impurities in solid phase. This invention forms a suppression mask film having windows selectively on a wafer, and grows impurity-containing films on the windows by vapor phase reaction in an open reaction tube. The impurities diffuse from the impurity-containing films to the wafer substrate in solid phase.      The impurity diffusion occurs either at the same time of the growth of the films or after the growth of the films at a different temperature. The compound semiconductor is covered with solid films during the impurity diffusion. This invention is immune from the difficulty of escape of elements of group V from the surface of a wafer.

Title: Integrated photographic processing system and procedure for operating the system
Inventor: KNECHT HUGO
IPC: G03D13/00
Filed: 1994-11-04
Abstract: Integrated photographic processing system and procedure for operating the system Abstract An integrated photographic processing system is equipped with a series of processing stations that are all arranged inside a shared housing. These include an input station for undeveloped, exposed roll film, e.g., miniature film coiled in film magazines. In this input station the inserted roll films are uncoiled and fed into a film conveyance system of an adjacent film processor. In the film processor, the photographic films are developed. At the output of the film processor, a projection printer is arranged for image-by-image exposure onto photographic paper of negatives contained on the developed film. The projection printer is equipped with its own conveyance system for the developed film. Finally, there are also a paper processor for developing the exposed photographic paper, and output stations for the developed film and the developed paper images. Between the output of the film processor and the projection printer, an intermediate storage is arranged for developed individual films; this storage is equipped with an automatic conveyance device for transferring the developed individual films to a film stage of the projection printer, and this conveyance device can be operated independently of the conveyance systems of the film processor and the projection printer. In an operating procedure ing to the invention, the developed films are completely removed from the film conveyance system of the film processor before further processing and are deposited in the intermediate storage. From there, they are then advanced by the automatic conveyance device of the intermediate storage to the projection printer.
