Title: Input signal processing apparatus for discrete waveform display device
Inventor: TAKEUCHI YASUTO
IPC: G01R13/34
Filed: 1988-11-22
Abstract: PURPOSE:To make it possible to display the peak value of the amplitude of an ECG (electrocardiogram) waveform by detecting and holding the peak value of an input signal waveform. CONSTITUTION:An amplifier A1 judges the polarity of an ECG signal and a switch S1 is turned ON and OFF. When the signal is positive, the ECG signal is inputted in the +terminal of an amplifier A2. When the signal is negative, the signal is inputted into the -terminal. Therefore, the amplifier A2 always outputs the positive signal. When the amplitude is in the increasing direction in an amplifier A3, a capacitor C1 is charged. The input signal is intactly inputted into an amplifier A4. When the output is changed into the decreasing direction, a transistor Q1 is cut off temporarily. The peak value is held in the capacitor C1 for at least a sampling rate period. The output of the amplifier A4 follows the change in input signal at a period other than the peak holding period. An amplifier A5 makes the output sign agree with the polarity of the input signal again. In this way, the value at the sampling point is replaced with the peak value. The peak value image of the peak value is displayed. Even if the sampling rate is coarse, the amplitude peak of the ECG waveform can be dis played approximately correctly.

Title: Semiconductor circuit
Inventor: MATSUMOTO KAZUYA
IPC: H03K19/0952
Filed: 1987-11-24
Abstract: PURPOSE:To reduce power consumption and to quickly charge/discharge load capacity by connecting the input terminal of a switch stage to the gate of a current source MESFET of a buffer stage through a capacitor and adding a bias diode between the source and drain of the FET. CONSTITUTION:When the input voltage of a terminal 19 is turned to its 'H' level, a MESFET 15 is turned on and a MESFET 16 is turned off. Consequently, the voltage of an output terminal 20 is turned to its 'L' level. Simultaneously with the rise of the input voltage to the 'H' level, the input voltage is impressed to the gate of a MESFET 17 and the voltage between the gate and source is turned to a positive value. Thereby, current flowing into the FET 17 is increased higher than the initial state, so that an output current goes high, load driving force is increased and the transfer of the output voltage to the L level is furthermore accelerated. The increased gate potential of the FET 17 is held by charge accumulated in a capacitor 13 and then gradually discharged through a Schottky gate of the FET 17 so as to close to zero.

Title: Printing control system of printer
Inventor: UEDA KENJI
IPC: B41J29/50
Filed: 1990-11-01
Abstract: PURPOSE:To prevent contamination of an internal mechanism or wasteful consumption of expendables by detecting the presence of a printing sheet in a horiaonral direction and restricting a printing action temporarily based on the detection results. CONSTITUTION:If a printer is ready to swing into a printing action and a printing head 1 moves to a position other than where the sheet is present, a printing sheet detection sensor 2 detects a state 'no printing sheet is present', and switches 'printing sheet present' signal 7 OFF. A printing sheet detection circuit 6 in a printing control circuit 3 switches a 'printing permit' signal 8 OFF with the switching OFF of the 'printing sheet present' signal 7. A printing signal 9 which is output from a printing circuit 10 is shut off at a gate circuit 4 by the 'printing permit' signal. Therefore, a printing head drive circuit 5 restricts the printing action of a printing head 1 so that no printing process takes place. If the printing head 1 reaches the surface of the printing sheet, the printing sheet detection sensor 2 detects the printing sheet and the 'printing sheet present' signal is switched ON. For this reason, the printing sheet detection circuit 6 connects the 'printing permit' signal 8 to drive the printing head 1 for printing action.

Title: Sound signal compressing method
Inventor: OKAZAKI KATSUHIKO
IPC: G10L19/00
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent data from being absent even when variation in a difference of a sound signal is small when the sound signal is compressed. SOLUTION: When a sound signal is sampled and converted from analog to digital and compressed, differences between the sampled data are found one after another and the quantity of variation between last and current differences is monitored. When this variation quantity becomes large, the sampling frequency is increased. When this variation quantity decreases, the sampling frequency is lowered. The data hold the repetition frequency of data having the same difference as the last one and the same data are repeated to save the memory.
