Abstract: A screwless hinge system for connecting a temple to a front frame portion of eyewear includes a hooked tab with a single hook and a base. The hooked tab extends through the front frame portion and a u-spring until the base engages the frame. A temple receiver of a temple compresses the u-spring and engages the single hook, allowing for opening and closing of the temple and removal and replacement of the temple without tools.

Abstract: A polarizable compact is provided with high productivity, which makes a polarizing sheet resistant to the occurrence of color unevenness and voids and also resistant to the occurrence of variations in polarization degree accompanying thermal shrinkage and the like of a protective layer (protective film). A polarizable compact is used for glasses, and a method of manufacturing the same. An injection-molded portion made of a transparent plastic material is thermally bonded to the concave surface side of a polarizing sheet having a predetermined curvature radius. The polarizing sheet has a polarizer layer held between first and second protective layers respectively serving as a convex surface side and a concave surface side. Both the first and second protective layers are formed from transparent films by a casting method with retardation (Re)?50 nm. The transparent films for the first and second protective layers are respectively formed from an acylcellulose-based film and a polyamide-based film.

Abstract: A plurality of individual circuits are formed on a substrate. Each of the individual circuits is formed with electrical contacts. A spacer is sealed onto the substrate, the spacer peripherally enclosing each of the individual circuits while exposing the conductive contacts. A cover is positioned over the spacer is and integral with it. First conductive feedthroughs penetrate the cover, the first conductive feedthroughs positioned peripheral to each of the individual circuits. Conductive pads are formed on a bottom surface of the cover, the conductive pads in electrical continuity with the conductive contacts of the individual circuits. Conductive paths are formed on the bottom surface of the cover, the conductive paths each joining at least one of the conductive pads with at least one of the first conductive feedthroughs thereby establishing electrical continuity between the individual circuits and the first conductive feedthroughs so as to establish pin-outs.

Abstract: An apparatus for detecting an amount of toner in a toner casing. A sensor detects the magnetic flux density of the toner in the toner casing and generates detection signals. A sampling device samples the detection signals. A selecting device selects a signal having the lowest value among the sampled signals. A device for setting up a threshold value determines the threshold value using the selected signal. A counting device counts the number of sampled signals lower than the threshold value. If the counted number is larger than a predetermined value, then an indicator lamp indicates that toner is lacking.

Abstract: An image forming device in which a toner on a sheet is heated by the heater of a fixing unit. The heater of the fixing unit is heated via a power supply. The temperature of the fixing unit is sensed by a temperature sensor. A controller increases the temperature of the fixing unit to a printing temperature in response to an output signal from the temperature sensor. When not printing, the controller turns off the power supply if the temperature of the fixing unit exceeds a set temperature (which set temperature is lower than the aforesaid printing temperature) and turns on the power supply if the temperature of the fixing unit is less than the set temperature.

Abstract: A shock absorbing member or construction is equipped in a labyrinth seal construction to absorb shocks of collision of annular projections on an annular member against a cylindrical surface of a sleeve disposed in another annular member, so that undesired breakage of the tops of the annular projections and formation of deep streaks on the cylindrical surface of the sleeve are prevented.

Abstract: A fuel supply control system for an engine includes a controller and a fuel supply line. In one embodiment, at least two parallel connected control valves are arranged in the line and are changed between open and closed states when energized by a drive signal. A sensor is provided for detecting an engine operating condition. A generator is provided for producing a random designation signal indicating any one of the different control valves. The controller produces a pulse train as the drive signal for the control valves in response to the output signal of the sensor so that the duty cycle of the pulse train varies with the engine operating condition. The controller distributes each pulse of the drive signal to any one of the control valves designated by the random designation signal of the generator to open the designated control valve so that any one of the control valves is opened in a random sequence. In a second embodiment, the number of the control valves may be one.

Abstract: A series of airfoil cross-section equidistantly spaced normally parallel vanes are disposed linearly across the mouth of an induction housing port which lies on an essentially flat plane non-intersecting with the axis of rotation of a turbo compressor wheel. A control mechanism moves the vanes upon the compressor tending to surge so that each of the vanes is moved through an angle different from the preceeding one, whereby the air flows passing between the vanes are deflected and converge upstream of the compressor wheel and swirl theretoward in the form of a single flow to impinge on the blades of the wheel with a uniform and reduced angle of incidence.
