Title: Differential surface acoustic wave filter
Inventor: EBARA NAGANORI
IPC: H03H9/64
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a differential surface acoustic wave filter which shows an excellent balun and filter characteristic without the need for increasing the circuit scale more than what is wanted. SOLUTION: When unbalanced electric signals are given between an unbalanced signal input terminal 320 and ground terminals 322, 324, 2-terminal pair surface acoustic wave circuits 302, 304 receive the electric signals. The electric signal received by the circuit 302 is converted into a surface acoustic wave signal and then converted again into an electric signal, and it is given to a 2-terminal pair surface acoustic wave circuit 306. The electric signal given to the circuit 306 is converted into a surface acoustic wave signal and then converted again into an electric signal and fed to a balanced output terminal 350. On the other hand, the electric signal received by the circuit 304 is converted into a surface acoustic wave signal and then converted again into an electric signal, and it is given to a 2-terminal pair surface acoustic wave circuit 308.  The electric signal given to the circuit 308 is converted into a surface acoustic wave signal and then converted again into an electric signal and fed to a balanced output terminal 352. In this case, the phase of the output electric signal with respect to the input electric signal in the circuits 302-308 differs by about 180 degrees. Thus, balanced signals with the same phase are outputted from the balanced output terminals 250, 352.

Abstract: PURPOSE:To facilitate the management of an automatic vending machine by inputting the reference luminous intensity value to turn on an illumination device to finely set the intensity value. CONSTITUTION:The reference luminous intensity value is digitally inputted from a keyboard 14 via a ten-key. An optical sensor 10 detects the peripheral brightness of an automatic vending machine and outputs an analog output signal in response to the detected brightness. A CPU 22 receives the digital output signal converted by an A/D converter 12 from the sensor 10 and also receives the digital reference luminous intensity value from a keyboard processing part 18. Then the CPU 22 compares these received signal and value with each other to turn on and off an illumination device 20 when the digital output signal is smaller and larger than the reference luminous intensity value respectively. Furthermore the CPU 22 shows the digital output signal received from the converter 12 on a display 16 via the part 18. Thus the manager of the vending machine can set the reference luminous intensity value based on the displayed digital output signal.

Title: Feeding device for paper sheet for printer
Inventor: NIITSUMA NOBUYUKI
IPC: B41J15/04
Filed: 1987-06-16
Abstract: PURPOSE:To feed paper sheet automatically when a roll of paper sheet is exhausted by arranging a setting space for two rolls of paper sheet so that when a 1st roll is exhausted a 2nd roll rolls and pushes a movable partition plate and that the partition plate causes the 2nd roll to be pressed against a transfer roller located at the bottom of the setting space. CONSTITUTION:Arranging a setting space for two rolls of paper sheet RP, the two rolls of paper sheet RP1 and RP2 are separated with a movable partition plate SP. If the amount of the 1st roll RP1 decreases, the movable partition plate SP is pressed up to a transfer guide H1 by the rolling of the 2nd roll RP2 due to the slope of a frame bottom surface F2a of the paper roll setting space. Furthermore, the partition plate SP presses the 2nd paper roll RP2 and brings it into contact with a transfer roller R2 arranged at the bottom surface of the setting space. When the exhaustion of the paper roll RP1 is detected, the transfer roller R2 is driven to automatically set the 2nd paper roll RP2. The automatic paper feed is thus performed.
