A credit transaction processing system processes data related to a commodity entered into by using a card (17) owned by a customer and a recording card (16) owned by a store. First, merchant transaction data necessary for a credit sale stored in the recording medium (16), such as account number data for the store, data specifying a credit company, and data representing an upper limit of an amount to to be sold through a credit sale, are read by a card reader (5), and then, customer transaction data stored in the customer's recording card, such as account number data of the customer, data specifying a credit company and an identification number or code is read. If and when the customer enters his identification number by a ten-key (7), a central processing unit (12) determines whether the entered identification number coincides with the identification number read out of the customer's card. If and when a coincidence occurs, it is determined whether data indicating the purchase price of the commodity purchased by the customer is lower than the upper limit of the amount to be sold through a credit sale. If so, the price data is transmitted to a center station (3) and the amount of the money required for the credit sale is transferred from the bank account of the credit company utilized by the customer to the bank account of the store.

Fuel efficient devices and methods for protecting an exhaust system, and components thereof, when the exhaust gas temperature increases excessively are provided. The exhaust gas temperature is estimated in response to an internal resistance of an Air/Fuel ratio sensor element. The estimated temperature is corrected in a transition time based on the exhaust gas flow rate and the engine's operating region. When the exhaust gas temperature reaches an upper limit (Tmax), a delay period is set in response to the change ratio of the exhaust gas temperature. The delay period is based on the margin of time before an exhaust system component reaches the allowable heat resistance temperature Tem. The delay period can be corrected based on the outside air temperature and the vehicle speed. After the delay time has elapsed, a fuel increment is started in order to decrease the exhaust temperature.

A data transfer circuit comprises a voltage/current converter circuit for converting a first binary voltage data of n bits (n is an integer equal to or larger than two) to multi-value current data of 2n values which is output to a single data transfer line. A current comparator circuit converts the multi-value current data on the data transfer line to binary current data of (2n−1) bits, and a current/voltage converter circuit converts the binary current data of the (2n−1) bits to second binary voltage data of (2n−1) bits. A counter circuit restores the first binary voltage data of the n bits from the second binary voltage data of the (2n−1) bits.

To obtain a clear-cut picture image by correcting a contour of a video signal of a natural picture image and the like from a computer. Video signals of, for example, three primary colors (R, G, B), including a natural picture image and the like produced by, for example, a computer from input terminals 1 are supplied to a mixing circuit (2) and mixed at a ratio of, for example, 0.6G+0.3R+0.1B to produce a signal corresponding to a luminance (Y). This signal is supplied to differentiation circuits 3A and 3B having different time constants each other and predetermined high frequency components are extracted therefrom, respectively, and these output signals are selected by a switch (4), and then supplied to an amplifying circuit 5. The gain of the amplifying circuit 5 is arbitrarily controlled by a signal from a control terminal (6). Then, a signal from the amplifying circuit (5) is supplied to adding circuits 7R, 7G and 7B and added therein to respective video signals of R, G and B to then be derived from output terminals 8R, 8G and 8B.

An apparatus and a method of positioning pallets on roller chains mounted on a free flow conveyor is basically composed of a detector for detecting an oncoming pallet, a stopper for stopping the pallet at an approximately required position, a controller capable of positioning the pallet in the x- and y-directions, and another controller capable of positioning the pallet in the z-direction. With an application of the foregoing method proposed, a device is designed to provide a highly accurate positioning of the pallet with a single device and therefore contributes greatly to an economization of operating costs.
