Title: Alphanumeric input terminal for entry of data to an access device
Inventor: HYATT RICHARD G JR
IPC: G07C9/00
Filed: 1993-10-01
Abstract: An alphanumeric input terminal (10) is shown in the figure which allows a user to enter a sequence of characters (40) that is compared to a stored valid entry code to determine whether access should be granted. The terminal (10) displays a random number which the user adjusts by a rotatable knob (30) to obtain a de-sired character (40). The character (40) is entered by pushing the knob (10). The entered character (40) is no longer displayed and the terminal displays another random character which is similarly adjusted and en-tered. This prevents observation of the characters (40) being entered since only one character (40) is displayed at any one time. By initially displaying a random char-acter for each entry position, the adjustment made by the user to reach the selected character (40) is different every time. This prevents one from determining the se-lected character (40) by observing the direction and ex-tent that the user rotates the knob (30) before entering the character (40).

Title: Non-reducing saccharide and its production and use
Inventor: KUBOTA MICHIO
IPC: A23L11/00
Filed: 1995-06-08
Abstract: Non-reducing  saccharides  including  alpha-glycosyl trehaloses,  alpha-glycosyl alpha-glycosides and trehalose are easily  produced  by  cultivating  microorganisms  capable  of producing non-reducing saccharide-forming enzyme  in nutrient culture media which  contain reducing  partial  starch hydro-lysates with glucose polymerization degrees of 3 or higher. The yields for these saccharides are significantly improved by further subjecting the reducing partial starch hydrolysates to starch-debranching  enzyme  and/or  cyclomaltodextrin  glucano-transferase in or not in culture media.  The resultant non- or less-reducing saccharides commonly bear desirable properties in addition to a mild and gentle sweetness.  Thus they would find extensive uses  in a variety of compositions  including  food products, cosmetics and medicines.

Title: Power Steering System with Minimum Pressure Maintained Within the Power Steering Motor
Inventor: LUIBRAND THOMAS W
IPC: B62D5/12
Filed: 1995-09-07
Abstract: A power steering system (10) for use in a vehicle includes a power steering pump (12) which is driven by an engine (13) of the vehicle.  The output from the power steering pump (12) is connected to a power steering valve (22). The power steering valve (22) is connected with a power steering motor (24).  When the engine (13) is turned off, that is, in a non-operating condition, and the power steering pump (12) is not being driven, the fluid pressure in motor cylinder chambers (40, 42) is prevented from falling below a predetermined pressure to keep seals (64, 66) in sealing engagement with the power steering motor 24. To keep the fluid pressure in the motor cylinder chambers (40, 42) from falling below a predetermined pressure, a one-way valve (70) blocks the flow of fluid from the power steering valve (22) back to the reservoir (16).  A pressure relief valve (72) blocks the flow of fluid from the power steering valve (22) to the reservoir (16) when the fluid pressure in the motor cylinder chambers (40, 42) is equal to or less than the predetermined pressure required to urge seals (64, 66) into sealing engagement with the power steering motor 24.
