Title: Orbiting nip plural mode sheet output with faceup or facedown stacking
Inventor: STEMMLE DENIS J
IPC: B65H39/11
Filed: 1993-02-22
Granted: 1998-05-19
Abstract: In a system of transporting sheets in an output path of a copier or printer to a sheet stacking area with opposing first and second sheet feeding rollers forming a sheet transporting nip engaging the leading edge of a sheet, while producing a relative orbital motion of the opposing rollers to progressively pivot the nip and thereby change the angular direction of motion of the leading edge of the sheet, plural mode selectable operation of this pivotal motion is provided. There is a selection between faceup and facedown stacking of the sheets by one selectable orbital motion of the nip. This selected orbital motionpivots the nip by greater than 90 degrees with the sheet's leading edge held in the nip, so that subsequently, the leading edge of the sheet is moving in a direction substantially different from the direction of motion of the leading edge when the leading edge first entered the nip, and the sheet is inverted. Another selectable orbital motion of the nip pivots the nip to feed the sheet into a separate area for further sheet processing. Another selectable orbital motion of the nip pivots the nip in the opposite direction to feed the sheet into a topstacking tray. Other selectable movements of the same orbiting nip unit can provide other output selections, such as a duplexing or highlight color sheet return, all without requiring any moving gates or baffles, and with positive sheet control.

Title: Light-receiving structure for waveguide type optical devices
Inventor: MATSUMOTO KIYOTO
IPC: G02B6/42
Filed: 1994-12-23
Granted: 2000-06-13
Abstract: A light-receiving structure for waveguide-type optical devices exhibits excellent productivity, is compactly-formed, and permits highly-efficient coupling. A recess is provided in part of the surface of a substrate on which an optical waveguide is formed, and a light-receiving element is mounted on the recess, with its light-receiving face upward. Near the recess is formed in advance an end face of the optical waveguide, so that a light is emitted therefrom. On the other hand, over the substrate is arranged a cover in which a groove is formed in a position opposite to the optical waveguide, and a reflector is formed in a position opposite to the light-receiving element. The light emitted from the optical waveguide is reflected by the reflector and coupled to the light-receiving element. A  through-hole can be bored in the substrate in advance so that the packaging density can be improved by mounting the light-receiving element on the underside of the substrate with the light-receiving face of the light-receiving element being directed toward the through-hole.

Abstract: An improved water quality monitor is provided for use in a water purification system of the type having a reverse osmosis unit for producing relatively pure water from a tap water supply. The reverse osmosis unit supplies produced purified water to a reservoir for storage until dispensing, as by opening a faucet valve. An inlet shut-off valve closes to prevent tap water inflow to the reverse osmosis unit when the reservoir reaches a substantially filled condition. The water quality monitor includes electrodes in contact with the tap water and the produced purified water to obtain comparative conductivity readings which represent the performance level of the reverse osmosis unit in removing impurities from the tap water inflow. The monitor includes a test circuit responsive to movement of the inlet shut-off valve to take a conductivity reading at a point in time substantially after the shut-off valve, opens to resume tap water inflow to the reverse osmosis unit, and substantially prior to shut-off valve closure when the reservoir reaches the filled condition. This conductivity reading is stored in memory for subsequent periodic display, for example, each time the faucet valve is opened, by energization of one or more indicator lights.

Title: Method of transmitting orthogonal frequency division multiplexing signal and receiver thereof
Inventor: HARADA YASUO
IPC: H04L27/26
Filed: 1996-01-04
Granted: 1999-06-01
Abstract: An orthogonal frequency division multiplexing signal transmitted from the transmitting end to the receiving end intermittently includes a particular symbol SO having a predetermined particular pattern in addition to a symbol Sm including data to be transmitted. At the receiving end, the variation in the receiving level and/or the variation in the frequency band of a received signal are detected and corrected on the basis of the received particular symbol SO. Since the particular symbol SO has a particular pattern, the variation in the level and/or the variation in the frequency are strongly correlated with the variation in the receiving level and/or the variation in the frequency band of the received signal. Consequently, the variation in the receiving level and/or the variation in the frequency band of the received signal can be accurately detected from the particular symbol SO and consequently high-precision correction can be made.

Abstract: It is an object of this invention to provide an electron generating apparatus which is hardly influenced by variations in driving voltage, an image forming apparatus using the electron generating apparatus, and a method of manufacturing and adjusting the same.  The row wiring layers of a multi-electron-beam source (300) are sequentially selectively switched by a control circuit (302) and applied with a pulse voltage having a value about 1.05 to 1.5 times the maximum value of a normal driving voltage from a DC voltage source (301).  The characteristics of all surface conduction electron-emitting devices of the multi-electron-beam source (300) are shifted to the high potential side.  With this process, even when the driving voltage becomes high due to superposition of noise and the driving voltage, variations in electron-emitting characteristics caused by the voltage shift characteristics of the surface conduction electron-emitting devices can be prevented.

Abstract: A hot-fillable, blow-molded plastic container having a reinforced dome which controls dome distortion otherwise caused by forces associated with hot-filling and shipping. In one embodiment, the reinforced dome resists distortion, and in a second embodiment, the reinforced dome enhances ovalization distortion. The container dome is bell-shaped with an inwardly extending waist and has a plurality of vertically extending grooves passing through the waist. Each groove is inwardly concave and extends from below the waist to adjacent the finish. Arcuate lands are formed between the grooves, and optionally, can have panels with a textured pattern which add to the aesthetic appearance of the container and which provide further stiffening of the dome. When two grooves are utilized, ovalization distortion is enhanced, and when three or more grooves are utilized, distortion is prevented.
