Title: Toner collecting device
Inventor: AOYAMA MAMORU
IPC: G03G21/10
Filed: 1987-09-02
Abstract: PURPOSE:To prevent a transfer material from being stained with toner, etc., by setting the conveyance quantity of a conveying means larger at the curved part of a conveyance part than at any other part. CONSTITUTION:The conveyance path 35 has the curved part formed of a U-shaped pipe 37, but the pitch P of the curved part 36b of an auger 36 and the teeth of the screw of a straight part 36c following it is set larger than that of a straight part 36a, and consequently even when toner conveyed by the auger 36 passes through the curved part of the conveyance path, the pitch P2 of the auger 36 is set larger at the curved part 36b than at the straight part 36a and the toner is collected efficiently to a toner recovery part 11 in a photosensitive drum 1. Therefore, the collected toner never fills the curved part of the conveyance path 35 to overflow from the end part of a cleaning device 13, so overflowing toner falls neither on a transfer form 8 to stain it or in the device to stain the inside.

Texture coordinates U and V are applied to polygons PLG1-PLG7 so that the arrangement repeating the texture blocks B1-B5 can be mapped on a course object 20. The texture coordinate is found by linear interpolation based on the length of the dividable texture and the length of the polygon. When a dividable number, a basic length and an effective length are defined as DN, BLT and ELT and the length of the object is defined as LO, the relational expression of ELT=DN×LO/[INTEGER(LO, BLT/DN)] is established. A texture for connection is prepared.

Title: Heating furnace controllable by atmosphere
Inventor: AMAYA MASAKI
IPC: C04B35/64
Filed: 1993-09-03
Abstract: PURPOSE:To improve the utilization efficiency of the heating furnace better than the conventional one and elevate the yield and quality of the products by modifying the flow of the atmosphere-controlling gas in an internal heating type atmosphere-controlling furnace. CONSTITUTION:Conventionally, the gas flow for controlling the atmosphere has been set in the countercurrent direction to the moving direction of the specimens to be sintered, but in this atmosphere-controlling type heating furnace, the gas flows in the crossing direction to that of the specimens moving (in the figure, the gas flows from the bottom to the top). Thus, the resistance of the flow ways is reduced and the gas can flow uniformly near the specimens to be sintered whereby the yield and quality of the products can be improved.

Title: Coordinate input device
Inventor: SUGANO MASASHI
IPC: G06F3/046
Filed: 1983-11-22
Abstract: PURPOSE:To attain coordinate detection with high accuracy by setting the relative distance between an input board and a detecting coil and the diameter of an opening face so as to allow the relative distance between them and the diameter to cancell the error mutually. CONSTITUTION:There is a difference between the actual position of the detection coil 2 and the calculated position when the relative distance between the input board 3 and the detection 2, that is the height of the detection coil 2 on the input board is a distance. The relation is considered at a range of d/4-3d/4, where (d) is a pitch of the conductor and the detected error shows a graph of negative slope. Furthermore, the shape of the opening face of the detection coil is circular with a radius (r) and the coordinate detection error shows a graph of positive slope and the detection error due to the height and the error due to the shape of opening face are complementary in the polarity. Thus, the error of the height (h) of the detection coil is corrected by selecting suitably r/d, i.e., the radius (r) of the opening face of the detection coil when h/d is given.
