Title: System for detecting peak value of input signal and offset cancelling method
Inventor: JEFFREY C LEE
IPC: H03K5/153
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To remove offsetting effects by permitting a storage capacitor which is connected to the first input of a comparator via an input capacitor and is connected to the output to generate voltage and permitting an output buffer to buffer capacitor voltage and to supply it to the second input of the comparator. SOLUTION: A storage capacitor CHOLD is charged to a voltage setting close to VDD. When a clock signal PHI1 becomes low and PHI2 becomes high, switches S3 114 and S4 116 close, a switch S1 110 opens and voltage remains on an input capacitor C1. When PHI1 becomes high, the switch S1 110 closes and analog input voltage VIN is made to pass through a terminal to which a comparator 102 is inverted. The comparator 102 compares voltage in a terminal to be inverted with voltage in a terminal which is not inverted. The output of the comparator 102 depends only on the input voltage VIN of a peak detector 100 and the output voltage VOUT of a buffer 108. Thus, the offset is canceled.

Title: Ink jet recording head
Inventor: KUBOTA KOJI
IPC: B41J2/055
Filed: 1990-05-01
Abstract: PURPOSE:To improve jetting efficiency of ink by transmitting a pressure wave generated by the pressing force of a piezoelectric actuator in the direction of a nozzle by an inclined face within an ink chamber. CONSTITUTION:When a signal is fed by a control circuit to a driving circuit and further to a signal electrode of a piezoelectric actuator 32a, a displacement force is generated because of the piezoelectric transverse displacement effect, and therefore the actuator 32a is contracted in a longitudinal direction. When the signal voltage impressed to the piezoelectric actuator 32a is released, the actuator 32a is returned to a direction of an arrow D1. Therefore, the piezoelectric actuator 32a is shifted as shown by a chain line. At this time, an inclined face 36 at an end of the piezoelectric actuator 32a pushes an ink chamber 37, so that the resulting pressure wave generated in the ink chamber 37 is transmitted directly to a nozzle 33. Therefore, the ink in the ink chamber 37 is jetted out from the nozzle 33 and printed onto a paper, etc. Since the pressure wave generated in the ink chamber is transmitted to the direction of the nozzle by the inclined face, the jetting efficiency is high and the response frequency is also high.

Title: Electronic angle measuring device
Inventor: ARAO MASAAKI
IPC: G01C1/06
Filed: 1984-06-06
Abstract: PURPOSE:To improve operatability, by performing measurement with actual time and display in the initial stage where the main scale of an encoder is rotated and by doing the same with high resolving capacity in the final stage where the scale is stopped. CONSTITUTION:As in the initial high-speed angle measuring stage (g) a pulse distance of a 4-division pulse (c) is limited, a monostablemultivibrator 14 applies an H-level signal (d) to an AND circuit 15 and the 4-division pulse (c) is introduced to the AND circuit 15 from a discriminating circuit and the AND circuit applies the H-level pulse to operate an FF16 and an output of the H-level signal to a CPU displays a measured angle in a display apparatus. In the high resolving angle measuring stage (h), as the pulse distance is elongated and the 4-division pulse c is not introduced from the discriminating circuit, the AND circuit does not issue the H pulse, the FF16 becomes inoperative, the H level signal (e) is introduced into CPU and a measured angle of high resolving capacity is displayed in the display apparatus. Thus, measurements and displays suited to requirements of an operator become available for betterment of the operatability.
