Abstract: PURPOSE:To reduce the total amount of money after tax by the input reduction amount of money by performing price reduction calculation while considering the input price reduction amount of money includes the reduction amount of money for the amount of a tax. CONSTITUTION:When the reduced amount is inputted with a reduction key 76, the reduced amount is subtracted from the total amount after tax and the total amount after the reduction is displayed out at a display part 9. Then when registration clearing operation is performed, from the reduced amount is subtracted from the total amount, the difference amount between the tax amounts before and after the reduction amount is subtracted is added, and the tax amount for the total amount after the obtained reduction is made is calculated. Then the tax amount for the total amount after the reduction and the total amount after tax are printed on a receipt together with the reduction amount and difference amount. Consequently, the reduction calculation is performed while the input reduction amount includes the reduction amount for the tax amount, so the total amount after tax is reduced by the input reduction amount.

Title: Magnetic recording and amplifying device
Inventor: MIHASHI YASUO
IPC: H04N9/802
Filed: 1987-03-20
Abstract: PURPOSE:To improve the resolution of a Y signal and to decrease the color bleeding of a C signal by making both the Y signal and the C signal into a high band, providing a pole in a phase correction and trap-attenuating an unnecessary signal mutually. CONSTITUTION:An FM modulated Y signal is added through an HPF 20, an amplifier 21, an LPF 22 and an amplifier 23 to an MIX circuit 6 and further, added through a frequency characteristic correcting circuit 7 to the MIX circuit 6. Here, a Y1 characteristic due to the HPF 20 and a Y2 characteristic due to the LPF 22 are added and come to be a general Y characteristic Y3. Thus, a high resolution Y signal is obtained in which the decreasing component of the FM side band of the Y signal is emphasized and corrected. Next, the low area converted C signal is added through an LPF 24, an amplifier 25, a phase correcting circuit 26 and an amplifier 27 to the MIX circuit 6. Thus, since a chroma band is spread, and close to the Butterworth characteristic of the amplitude constant and phase constant, the color bleeding is eliminated.

Title: Manufacture of board for printed circuit using polyisoimide
IPC: H05K3/38
Filed: 1992-03-25
Abstract: PURPOSE:To obtain a board for a printed circuit having excellent heat resistance and exhibiting excellent adhesive strength without necessity of a high temperature in an adhering step by impregnating a fiber-reinforced material with polyisoimide solution prepared by transforming polyamic acid into polyimide. CONSTITUTION:Aromatic tetracarboxylic bianhydride and aromatic diamine are polymerized in a diamine excessive state. Then, their both ends are sealed with dicarboxylic anhydride and/or its derivatives. Thereafter, the obtained polyamic acid is isoimided to obtain polyisoimide solution. A fibrous reinforcing material is impregnated with the solution, and solvent is removed at 150 deg.C or lower to obtain prepreg. Then, the prepreg and a conductor foil are superposed, heated and pressurized. Thus, since an isoimide ring is transformed to an imide ring after thermal curing without necessity of heating and pressurizing steps, a board for a printed circuit which exhibits heat resistance of the same degree as that of ordinary polyimide is obtained.
