Abstract: PURPOSE:To easily perform a corrective operation by subtracting a taxable amount included in amount data in a preceding registration memory from a sale tabulation memory, and adding an amount in which the taxable amount is subtracted from the amount data in a taxable amount memory when an untaxable/inner multiplication correction key is depressed. CONSTITUTION:When such operation that an inner multiplication registration operation is performed for goods registered previously for which untaxable registration should be performed, or that the untaxable operation is performed for the goods for which the inner multiplication registration should be performed is performed in the middle way of performing the registration of the goods, the untaxable/inner multiplication correction key 38 is depressed. Then, it is judged whether the untaxable registration or the inner multiplication registration is performed for the goods registered previously from the state of a tax multiplication designation flag memory 48. When the untaxable registration is applied, the taxable amount included in the amount data in the preceding registration memory 43 is subtracted from the sale tabulation memory 44, and also, the amount in which the taxable amount is subtracted from the amount data is added on the taxable amount memory 45. In such a way, the corrective operation can be easily and quickly performed.

Title: Memory address setting mistake detection circuit
Inventor: HIROMOTO SATORU
IPC: G06F12/16
Filed: 1990-08-20
Abstract: PURPOSE:To shorten time till a device becomes capable of being used after power supply is switched on by providing a circuit which decides that there is an error in the setting of a switch when two or more select signals become active or when even one address low signal is active and in addition, all the select signals are inactive. CONSTITUTION:The detection circuit 6 decides that there is the overlap of a memory address when two or more select signals among the select signals 7a, 7b,... become active. Besides, the wired-OR-connected address low signals 11a, 11b,... are inputted to the detection circuit 6 as being low-active on the whole if even one of them becomes low active. At that time, if all the select signals 7a, 7b,... connected to the detection circuit 6 are inactive, it is decided that a space area exists on memory space, and the detection circuit 6 makes an error signal 8 active, and outputs it. Thus, since the presence of erroneous setting on a memory package can be decided, the time until the device becomes to a usable state after the power supply is switched on can be made minimum.

Title: Detector for leak of cooling medium in heat exchanger
Inventor: KODAMA TATSUAKI
IPC: G01M3/04
Filed: 1982-12-16
Abstract: PURPOSE:To facilitate the detection of leak, by sealing a liquid, which is not evaporated, in a leading-out tube or a detecting groove pushing out the sealed liquid to the detection end by the expansion of a cooling medium which is made gaseous when the leak of the cooling medium occurs. CONSTITUTION:In a leak detector, a heat exchanger 1, a compressor 2, an expansion valve 3, an evaporator 4, etc. are connected with a cooling medium piping to constitute a heat pump cycle. A leading-out tube 13 is formed into a U shape, and the liquid which is difficult to evaporate at a use temperature is stored in the bottom of the tube 13. In this constitution, when the cooling medium leaks to the side of a tube 8 with leak detecting groove, the cooling medium is evaporated to increase the volume and pushes up the liquid in the leading-out tube 13 to flow it to a leak detection end 14. In this invention, detection is facilitated because the volume expansion which is generated when the cooling medium becomes gaseous is converted to a displacement of the liquid.
