Title: Check valve
Inventor: GOMI CHIKASHI
IPC: F16K15/18
Filed: 1990-06-05
Abstract: PURPOSE:To simplify a valve structure and secure a more reliable valve closing condition by restricting a reciprocated valve unit to the valve closing position by means of a lock device actuated by one touch operation. CONSTITUTION:A lock device 2 comprises a lock lever 4 possible to reciprocate at a right angle to a direction of reciprocating a valve unit 3, spring 5 for resiliently urging the lock lever in a direction of approaching the valve unit 3 and an operating lever 6 for moving the lock lever 4 by one touch operation against or by resilient force of the spring 5, and the valve unit 3 is restricted to a closing position by stopping an internal end part 4a of the lock lever 4 to a shaft end part 3a of the valve unit 3 when the lock lever 4 approaches the valve unit 3. A cam mechanism is formed by forming a slope 4b in the internal end part 4a of the lock lever 4. Next, the operating lever 6 is flexibly connected to an external end part 4c of the lock lever 4 by a pin 7 so as to place the lock lever 4 distant from the valve unit 3, when the operating lever 6 is extended, and to stop the internal end part 4a of the lock lever 4 to the shaft end part 3a of the valve unit 3 when the lever is flexed. A protrusion 8b for limiting a rotational operating surface of the lock lever 4 is provided. Further, the valve unit 3, having a valve seat surface 3c of elastic material, is resiliently urged in a closing direction by a coil spring 9. In this way, a check function at reverse flow time can be more surely maintained, and a valve can be operated in a very short time with operation facilitated.

Title: Variable magnification image forming device
Inventor: YAMAUCHI KUNIHIRO
IPC: G03B27/34
Filed: 1984-07-16
Abstract: PURPOSE:To prevent the degradation in image quality due to out-of-focus for the position change of an optical member and to simplify the adjustment for correcting the extent of movement of the optical member by calculating the number of pulses which are required for movement of the optical member between two detecting members. CONSTITUTION:An optical member 1 is attached to an endless belt 2 and is moved along the optical path connecting an original and a photosensitive body by driving of a pulse motor 3. A detecting member 5 detects an operation piece 4 of the optical member 1 for a prescribed focusing magnification and positions it. A detecting member 6 is attached to the position indicating the deviation of a lens, which is used in the optical member 1 positioned by the detecting member 5, from the reference focal length and detects the operation piece 4 when the lens is moved for focusing. The number of pulses of the pulse motor 3 required for movement of the optical member 1 between detecting members 5 and 6 is counted by a correcting means 9, and the extent of movement of the lens for the position change of the optical member 1 is corrected in accordance with the obtained focal length of the lens. Thus, in-focus images of good quality are always obtained though the magnification is changed.

Title: Converter
Inventor: ISHIKAWA KAZUMASA
IPC: G01H9/00
Filed: 1986-06-26
Abstract: PURPOSE:To obtain a converter free of electromagnetic trouble and capable of outputting a signal having a high S/N ratio, by optically detecting and processing the change in laser beam projected to a sensing member displacing or deforming corresponding to the change in physical quantity such as pressure. CONSTITUTION:When pressure of sound pressure acts on a vibration film 10, the film 10 deforms into a spherical surface shape corresponding to the pressure or the like. Now, divergent luminous flux linearily polarized is emitted from a semiconductive laser 11 and converted to parallel luminous flux by a collimator lens 12 to be incident on a polarizing beam splitter 13. The incident parallel luminous flux is reflected by a polarizing film 13a and transmitted through a 1/4 wavelength plate 14 to be incident to the film 10. The reflected luminous flux from the film 10 again transmits through the 1/4 wavelength plate 14 and the polarizing film 13a to be incident on a critical angle prism 15 and reflected from the optical surface 15a thereof to be incident to a beam detector 16. The beam detector 16 has beam receiving regions 16a, 16b divided into two and converts the luminous flux incident to both beam receiving regions 16a, 16b to an electric signal which is, in turn, outputted to a differential amplifier 17 to form a difference signal. By this constitution, the adverse effect due to an electromagnetic factor from the outside is prevented and a S/N ratio can be enhanced.

Filed: 1991-06-20
Abstract: PURPOSE:To prevent deterioration in the electrooptic characteristics of the time-division driving of an antiferroelectric liquid crystal element which shows tri-state switching behavior by shortening a screen scanning time, reducing a display flicker, and suppressing the partiality of charges due to the self- polarization of liquid crystal.

The flicker is suppressed by inverting the polarity of a bias electric field, impressed in a nonselection period, plural times in one frame. Further, the polarity of a pulse impressed for a 1st time in the selection period corresponding to a state selected in a last frame is uniformed to shorten the time required for relaxation from a ferroelectric phase to an anitferroelectric phase, thereby enabling high-speed scanning operation.
