Title: Semiconductor memory having individual time-out control for reading and writing operations
Inventor: TOOMASU EI KOOKAA
IPC: G11C8/18
Filed: 1991-12-13
Abstract: PURPOSE: To make the speed of a read operation to be faster than a write operation and to reduce power consumption by providing a circuit for selecting first and second delay routes with the read operation or the write operation. CONSTITUTION: The shift of a line DWL to a high logic level advances in a ripple form through a delay gate in a write chain. Since the number of the delay gates of the write chain is larger than the number of the delay gates of a read chain, time required for shifting the line TOW to a low level after the line DWL shifts to a high state becomes longer than time when TOR shifts. Thus, the time out of the line TO is delayed for longer time by a write cycle compared to a read cycle. Consequently, the write operation takes longer time than the read operation, the write operation is made precise and the power of the read operation is reduced.

Title: Container inverting device
Inventor: SAKAKAWA YASUHIRO
IPC: B65G47/86
Filed: 1989-12-20
Abstract: PURPOSE:To decrease the wear between a cam rail and a pair of cam followers and to facilitate the operation to assemble the cam rail by maintaining a container in an erecting or inverted state while restricting the rotation of a gripping member by means of stoppers and forming the cam rail in such a manner that the cam rail can be disengaged and engaged from and with the cam followers. CONSTITUTION:A pair of the cam followers 50, the gripping member 37 and a gripper 25 are integrally rotated by the cam rail 51. The rotation of the gripping member 37 is restricted by the stoppers S1, S2 when the container gripped by the gripper 25 is rotated to the erecting or inverted state. Since the spacing between a pair of the cam followers 50 gripping the cam rail 51 is so set as to expand the outer side, the cam rail 51 can easily be disengaged from between the cam followers 50 to the outer side or engaged with the necessary positions while the rotation of the gripping member 37 is held restricted by the stoppers S1, S2. The wear between the cam rail 51 and the cam followers 50 is, therefore, decreased by disengaging the former from the latter. Since there is no need for providing the cam rail 51 in the prescribed position with high accuracy in the disengaged part, the assembling operation is facilitated.

Filed: 1988-12-29
Abstract: PURPOSE:To decrease the variation width of the diameter of pixels under constant recording conditions and modulate the diameter of dots to realize easy density gradation recording and further line print recording by applying voltage to a signal electrode in accordance with an image signal to increase the viscosity of ink from an ejection aperture and discontinuing application of the voltage to allow an attracting electrode to attract ink to be sent flying to an object to be recorded on in liquid droplets for printing. CONSTITUTION:An ink head 1 has a discharge aperture 2 at the tip and contains ink 3 which becomes solid or viscous significantly by an electric field inside. Then if an image signal which is output from a computer during image formation, switches 13, 14 are turned OFF to cancel or reduce voltage applied to signal electrodes 6, 6' from a DC power supply 11. Consequently, the viscosity of ink in the discharge aperture 2 addresses. In the meantime, a specified voltage is constantly applied to an attracting electrode 9 from a DC power supply 12, and ink 3 is attracted by this voltage and sent flying from the discharge aperture 2 to form an image on recording paper 8. Consequently, the flow of ink is stopped by application of a low voltage to the signal electrode and an image of constant size is obtained without 'image tailing'. In addition, no significant misalignment of a dot position occurs.
