Inventor: MURAKAMI KAZUNORI
IPC: G02B7/00
Filed: 1994-08-12
Abstract: An optical scanning device for leading a laser beam emitted from a semiconductor laser diode through a collimator lens, an imaging lens, and a cylindrical lens to a plurality of reflecting surfaces of a rotatable polygon mirror, and scanning a surface to be scanned movable in a vertical scanning direction with the laser beam reflected on the reflecting surfaces of the polygon mirror and transmitted through a correcting lens. The optical centers of the semiconductor laser diode, the collimator lens, the cylindrical lens, a return mirror, and the correcting lens are located in a plane containing an axis of rotation of the polygon mirror. The semiconductor laser diode, the collimator lens, and the cylindrical lens are located over an upper surface of the polygon mirror. Accordingly, an optical system can be formed in symmetry with respect to a center axis of an optical path of a horizontal scanning light beam from the polygon mirror without interference of the semiconductor laser diode, etc. with the optical path of the horizontal scanning light beam. Thus, the size and weight of the optical scanning device can be reduced, and the optical characteristics and the productivity of the optical scanning device can be improved.

Title: Boiler
Inventor: FRISCHKNECHT ARMIN
IPC: F24H9/06
Filed: 1994-02-24
Abstract: The boiler arrangement (2) has a frame (5) in which the boiler (3) is held. The frame legs (7) are telescopically extendable. Owing to the extendability of the frame legs (7), simple installation of the boiler arrangement (2) in niches of residential rooms is possible, as well as a stretcher-like construction of the boiler arrangement (2) for its transportation. A shelf can be fitted in the space bounded by the frame legs (7). By using a one-piece boiler heat insulation (1), there are no heat losses due to the stack effect, as in the case of multi-piece insulations. In addition, the insulation can be removed simply by cutting it open. An advantageously designed sacrificial-electrode arrangement permits easy mounting and dismounting. <IMAGE>

Abstract: A method for operating a glass pane bending press, in automatic vehicle glazing mfr., involves: (a) lowering a bent glass pane, held by a vacuum holder below the male mould, by downward motion of the upper press crossbeam onto a shuttle ring held at a constant level above the female mould; (b) controlling the downward motion according to a velocity curve having an initial acceleration portion, a max. velocity section and a subsequent deceleration portion for gently laying the pane on the shuttle ring; and (c) designing the curve such that the first diversion of the curve progresses without singularities. The reduced pressure of the vacuum holder matches the pane wt. and the deceleration of the downward motion is adapted to this reduced pressure so that the vacuum holding force is always greater than the counter-force resulting from deceleration and such that the pane is not released from the male mould during deceleration. After redn. or switch-off of the reduced pressure, the pane is laid on the shuttle ring. <IMAGE>

Abstract: Occulting apparatus (40) for use with an image generator (10) that provides for multiple-level occulting of image data. The occulting apparatus (30) comprises a mask buffer (50) and control logic (40) for processing image data to construct and store an obscurance mask in the mask buffer. Foreground entities contained in the image data are logically ORed into the mask buffer until the entities extend beyond a predefined range from a predetermined image viewpoint. Thereafter, the mask is used by the control logic to reject entities contained in subsequently processed image data that are fully obscured by the foreground entities comprising the obscurance mask. The control logic (40) includes an obscurance manager (41), a region processor (42), an object processor (43), a polygon processor (44), and insertion logic (45). The obscurance manager (41) is a controller for building and applying the obscurance mask to the image data. The region, object, and polygon processors (42, 43, 44) respectively process regions, objects, and polygons in the image to determine if they are obscured, reject obscured entities, and transmits unobscured entities to subsequent processors. The insertion logic (45) processes unobscured polygons and applies them to the obscurance manager (41) for storage and use by the respective region, object, and polygon processors (42, 43, 44). The present invention performs real-time occulting of all objects in an image scene, whether they are fixed or moving. Hidden area modules (large groups of objects in a geographic region), single objects, polygons, and pixels are sequentially filtered-out in real-time. The mask buffer (50) and control logic (40) provide three levels of occulting. A hybrid Z-buffer (51) provides pixel-level occulting. The present invention rejects regions, objects, and polygons, early in the graphics processing pipeline to reduce the number of required pixel processing computational elements in the image generator. By rendering objects generally from front to back, entities that are completely hidden by nearer objects can be detected and discarded before tiling and pixel processing.

Abstract: A reproduced signal is digitized so as to count a time interval of a specified pattern simultaneously with the count of a clock period of a phase lock loop circuit. A phase lock loop clock frequency is subjected to a feedback control based on the information indicating the difference between the time interval and the clock period. In this manner, a frequency loop performs a feedback operation so that a frequency of the reproduced signal falls within a capture range of a phase lock-in, thereby increasing the speed of phase lock-in.

Abstract: A method of pulse width modulation using a spatial light modulator (40) with a finite transition time. The method uses m bits per sample to digitize the incoming data, but apportions the LSB times for pulse width modulation based upon m-1 bits. The current video frame displays all of the bits for each sample, except for the LSBs for each sample. The next video frame displays all of the bits for each sample, adding one more LSB for dividing up the frame time. The first frame could use either the additional LSB time and display no data, or it could use only that number of LSB times it needs. In the latter, the system will have to adjust to different partitions of the frame time for alternating frames. The system includes a spatial light modulator (40), a memory (42), a formatter (48), a sequence controller (44) and a toggle circuit (46), to perform this method.

Abstract: A rust-preventing cover mounting structure is provided in which ease of mounting and removing a rust-preventing cover is improved without an increase in a number of parts thereof. Anchor portions (24), which are separably anchored to hub nuts (18) due to elastic deformation of the anchor portions, are provided integrally with the rust-preventing cover (20) at positions thereof corresponding to the hub nuts (18). Therefore, operations for inserting and removing fastening members, which are separate parts, are unnecessary, and time and labor involved in mounting and removing the rust-preventing cover can be saved. Accordingly, the ease of mounting and removing the rust-preventing cover (20) to a wheel (14) can be improved. Further, because the anchor portions (24) are formed integrally with the rust-preventing cover (20), a number of parts does not increase, and a manufacturing cost can be kept down.

Abstract: A current reference cell is used to generate stable currents using a voltage reference source such as a band gap reference voltage in order that the output current I out  can be proportional to absolute temperature, making the reference cell suitable for providing the bias current of a bipolar transistor in order that dynamic changes of collector current will be proportional to corresponding changes of base emitter voltage irrespective of temperature. The invention is concerned with rapidly turning off such a current I out , and a switch such as transistor Q7 is provided which is put into saturation when the reference voltage and hence reference cell are turned off, in order that current decaying via any large capacitor such as C1 connected to the output of the reference cell is diverted through such a switch rather than through the reference cell.
