IPC: G02B7/04
Filed: 1993-01-25
Abstract: PURPOSE:To provide a lightweight and small-sized lens driving device in which a leans holding frame is never shaken when moved by utilizing a feed screw as a second guide bar. CONSTITUTION:When a stepping motor 3 is driven, a feed screw 14 is rotated through the shaft of the motor, a thrust in the optical axis direction is added to a sleeve part 16b geared with the screw part of the feed screw 14 and a rack 15, whereby a lens holding frame is moved in the optical axis direction while being guided by a guide bar 4. Since the rack 15 is pressed onto the wall surface of the thread groove of the screw 14 by a spring 6, at this time, no looseness is formed between the tooth of the rack 15 and the ridge of the screw 14, and the holding frame 16 is moved without shaking. Thus, one guide bar can be abolished, compared with a conventional structure.

Title: Ink jet recording head
Inventor: KUBOTA KOJI
IPC: B41J2/015
Filed: 1995-01-26
Abstract: PURPOSE: To reduce power consumption and to shorten a radiation time to realize high speed response by providing a valve element operated by thermal deformation and controlling the propagation of the pressure from an emitting pressure generating source by the valve element to emit ink droplets. CONSTITUTION: A valve element 9 is integrally constituted of a shutter piece 31 and a thermal deformation plate 30 on a silicon substrate. When a current supply pulse is applied to the thermal deformation plate 30 before a drive pulse is applied to a piezoelectric element, Joule heat is generated and the thermal deformation plate 30 is thermally expanded and deformed. As a result, the shutter piece 31 is moved in the direction vertical to an ink channel to bring an ink passing hole from an open state to a closed state. After a piezoelectric element driving pulse falls, the current supply pulse is cut off to bring the ink passing hole to the original open state.  When an ink droplet is emitted, no current is supplied and the valve element 9 is held to an open state as it is and the impulse pressure generated by the piezoelectric element becomes the ink droplet emitting pressure as it is. The moving distance of the shutter piece 31 is required in predetermined quantity or more but energy itself may be small. The length of the thermal deformation plate 30 is required in predetermined quantity but the width and thickness thereof may be small.

Filed: 1985-01-25
Abstract: PURPOSE:To prevent the generation of engine vibration and improve drivability by suppressing injection of fuel on start and jetting out fuel in ordinary case when the engine revolution speed and car speed satisfy specific conditions. CONSTITUTION:When a starter switch is turned-ON, fuel is jetted out, and an engine starts combustion. When the engine completes combustion and the starter switch is turned-OFF after start, the number Ne of engine revolution and car speed Va are detected. When the number of engine revolution Ne is over a set value Ns, fuel is jetted out normally.
