Title: Echo signal canceller
Inventor: MINAMI SHIGENOBU
IPC: H04B3/23
Filed: 1984-06-18
Abstract: PURPOSE:To prevent an error generated once from being consecutive by detecting an error at norm calculation using a recurrence formula and clearing a system when an error takes place. CONSTITUTION:The norm value is used for execution of the study identification algorithm in a tap coefficient correction circuit. The 1st signal is obtained by applying 1 samle shift at a shift register 32. Further, X(k-1) of a shift register 21 and X(k-n-1) obtained by the shift register 31 are squared respectively by multipliers 35, 37 and the 2nd signal is obtained by accumulating it at an accumulator 34. Then the 1st and 2nd signal values are compared by a comparator 33 and when dissidence is detected, it is discriminated as an error in a norm calculation circuit and the entire system is initialized.

Abstract: PURPOSE:To facilitate transmission shift operations in a transmission which performs both forward/reverse shift and stepless transmission by means of a single operation lever by applying brake action on an output shaft when the operation lever is in a position for changing forward/reverse directions. CONSTITUTION:When an operation lever 26 is moved along a side of a guide groove 27, a sliding sheave 10 of a drive side speed changing pulley 4 moves in the axial direction due to the movements of link mechanisms 35-42 to change the transmission ratio. When the operation lever is moved to the lowest speed side, a V-belt becomes to be supported by an idling body 16 of the drive side speed changing pulley 4 of the stepless transmission, making the rotation of driven transmission pulley 19 stop. At the same time, a brake body 24 of an intermediate transmitting member 20 is activated by the action of a brake arm to stop the rotation of an output shaft 21. If the operation lever 26 is moved in the right-angle direction under this condition, rotating direction of the intermediate transmitting member 20 is reversed by the action of a shift arm.

Title: Direct current component reproducing circuit
Inventor: YAMAZAKI MASAO
IPC: H04N5/18
Filed: 1989-05-18
Abstract: PURPOSE:To compensate the temperature variation of the regenerated DC component of the DC component regenerating circuit by providing a diode for compensating the temperature variation of the regenerated DC component. CONSTITUTION:When the ambient temperature rises, the forward voltage VF6 across the diode 6 has a negative temperature coefficient, so the forward voltage VF6 across the diode 6 drops and the potential at a point (d) which is obtained by dividing the forward voltage VF6 across the diode 6 by resistances 3 and 4 drops. At this time, the forward voltage VF2 across the diode 2 has a negative temperature coefficient and, therefore, drops, so the temperature variation of the regenerated DC component obtained by subtracting the forward voltage VF2 across a diode 2 from the potential at the point (d) can be compensated by selecting the resistances 3 and 4, and the temperature coefficient value of the forward voltage VF6 across the diode 6. Thus, the diode 6 for compensating the temperature variation of the regenerated DC component of the DC component regenerating circuit is provided to compensate the temperature variation of the regenerated DC component.

Abstract: PURPOSE:To obtain an ink jet head having high energy efficiency, by constituting the title head so that the ink present in the gap between a nozzle forming member and a cantilevered beam like vibrator is not brought into contact with the vicinal part of the fixed end of the cantilevered beam like vibrator. CONSTITUTION:The ink present in the gap between a nozzle plate 22 and a cantilevered beam like vibrator 52 is prevented from the contact with the vicinal part of the fixed end of the vibrator 52. As a result, the resistance and inertia added in the same minute gap (a) when the vibrator 52 is displaced in the ink corresponding to an electric signal become small as compared with such a case that the gap between the vibrator 52 and the nozzle plate 22 is entirely filled with ink. Therefore, the vibrator 52 can reach the final displacement while performs damping vibration having a long time constant and the max. value of ink emitting pressure is largely taken and the time reaching the max. emitting pressure can be shortened. Therefore, an ink jet head excellent in energy efficiency can be realized.
