Abstract: An automatic transaction machine comprises reading means (61, 62) for reading data recorded in a transaction medium (CD, PB) operation guidance means (51) for guiding an operation by the user, input means (50, 52) for inputting necessary data by the user according to the operation guidance means (51) and a controller (60) which selectively executes operation of the machine in one or another input processing mode in accordance with data read from the transaction medium (CD, PB). In the one mode, the controller (60) controls the operation guidance means (51) so that the transaction amount is input after inputting a secret number through the input means (50, 52) and after a validity check has been carried out. In the other mode, the controller (60) controls the operation guidance means (51) so that a transaction amount is input through the input means (50, 52) directly after a validity check of the data read out of the transaction medium (CD, PB) without inputting a secret number identifying the user.

Abstract: In an apparatus, such as an 8 mm video tape recorder, for magnetically recording and/or reproducing an information signal, and which records index signals (CDIX) representing various data in the tracks (2) in which the information signal is recorded, code signals (ISTC, IENC) indicative of the start point and the end point, respectively, of the index signal (CDIX) are recorded at the start and the end, respectively, of the recorded index signal (CDIX). In the reproducing mode, when the start code (ISTC) is obtained, the following blocks (BLK1 to BLK6) representing the index signal (CDIX) are taken in and, when the end code (IENC) is obtained such blocks (BLK1 to BLK6) are latched and subject to the reproducing processing while further taking in of the index signal (CDIX) is inhibited for several horizontal line periods.

Abstract: A pressure transducer (49), which senses clutch pressure and effects closed loop clutch control in a continuously variable transmission (25), is used after the clutch is fully engaged to provide closed loop line pressure control to a desired setpoint, which line pressure regulates the tension on the belt (29) in the transmission. Only a single transducer (49) is needed since there is a known relationship between the clutch and line pressures when the clutch is locked up. Prior to lockup, the line pressure is governed by an open loop controller (86,75,74) which establishes the line pressure at a level higher than that called for by the setpoint. This ensures that the line pressure will be high enough to provide the required tension on the belt so that it will not slip. After the clutch is engaged, the closed loop line pressure controller (86,93,75,74,78,49,79,88,89,91,92,94,95,96,97) establishes the line pressure at the setpoint. For stable operation, the closed loop controller responds only to relatively slow changes of the setpoint. In response to fast changes, the closed loop controller is made ineffective so that the line pressure will be determined only by the open loop controller and will be greater than the level called for by the setpoint.

Abstract: Synchronous array logic circuitry and a system for automatically laying out such circuitry for the fabrication of integrated circuits are described. The synchronous array logic circuitry includes as many cells (10, 20...) as necessary to perform the desired functions with each cell including a transistor array (12) for evaluating a Boolean function and supplying the result to a storage element (18) through a multiplexer (15). The storage element (18) latches the output signal and supplies it to other transistor arrays and/or other cells. The transistor array (12) includes serially connected transistors for performing AND functions and parallel connected transistors for performing OR functions. The multiplexer (15) operates under control of a test signal to configure the storage elements serially, thereby enabling complete testability of all cells (10, 20). 
     Our system includes a method for automatically laying out such circuitry. The method includes steps of arranging the storage elements (18) in a desired order, assigning transistors within a given cell to positions along a first axis, assigning transistors within the cell to a position along a perpendicular axis, and laying out an interconnecting diffusion path. Once all cells are specified, the cells may be interconnected in a desired manner.

Abstract: To protect the programs contained in a system memory and to check their integrity, the programs are in each case coded in accordance with a symmetric cryptographic algorithm, by using a secret key which is stored protected against reading and during this process a test number is formed for each program and is stored in the system memory. For the integrity check, the programs are then again coded in the same manner and the test number obtained in each case during this process is compared with the test number stored during the first coding process. From the result of the comparison, a criterion can be derived for activating or blocking subsequent programs. <IMAGE>

Abstract: This invention relates to a method for generating character images using a font compression algorithm that reduces the storage requirements associated with low-cost, high resolution printers. An expanded character image has original print slices and duplicate print slices identical to one or more of the original print slices where the duplicate print slices are eliminated in the compressed character image. The compressed character is expanded using a repetition mask that identifies the number and location of the duplicate print slices. The technique for expanding the compressed character is such that printing can be performed in real time, in either a forward or reverse direction with only minimal effects on processing. This invention also provides a means for supporting multiple pitches, such as 10 CPI, 12 CPI and Proportional Space Mode (PSM), within those storage constraints. The technique of this invention is efficient enough to be performed by microcode in real time, yet provides for significant reduction in the overall memory required for storing the font data.

Abstract: The invention relates to a method and a device for determining motor vehicle engine power on a roller test bed, the rollers of which can be braked with a constant braking force. According to the invention, the net power, effective at the vehicle wheels, of the vehicle engine is determined in a first measuring operation by detecting the braking power acting on the test-bed rollers. In a second measuring operation, the deceleration time (t1) within which the speed decreases from one predetermined value (v1) to a second predetermined value (v2) with the test-bed rollers unbraked is measured. In a third measuring operation, the test-bed rollers are braked with a constant braking force and the deceleration time (t2) within which the speed decreases from the initial value (v1) to the initial value (v2) is measured. This is followed by a calculation of the internal power loss (Px) of the motor vehicle in accordance with the equation
 Px = F2.t2.v2 DIVIDED (t1-t2).3600 [kW]
 The gross power of the vehicle engine can be determined by adding the calculated power loss to the previously measured net power.
