Title: Information display device
Inventor: HOSHINA KOSUKE
IPC: G09G3/24
Filed: 1990-05-18
Abstract: PURPOSE:To prevent the deterioration of the luminous intensity of emitted light caused by temperature rise by switching a display position on a display surface in the case of changing display. CONSTITUTION:Luminous display elements D1-D64 are taken as display dots, which are longitudinally and laterally disposed in a matrix state and allowed to emit light. Then, a means for changing the position of the display dot which starts the display in the case of changing the display is provided. Namely, shift registers SR1-SR8 are used as means for transferring display command data from a storage circuit MEM1 to the driving circuit of the light emitting diodes D1-D64 and the position of the display is changed by controlling the number of data transfer. Therefore, the identical display dot is not kept lighting and all of the display dots are averagely lighted. Thus, the deterioration of the luminous intensity and the temperature rise are reduced in the display element like the light emitting diodes D1-D64.

Title: Character data generator
Inventor: IKEDA HIROYUKI
IPC: B41J2/485
Filed: 1989-05-19
Abstract: PURPOSE:To express characters of high definition without raising the cost by expanding compressed data, which is obtained by compressing character data, by a data expanding means. CONSTITUTION:Compressed data obtained by subjecting character data from a storage means 13 to compression processing is expanded by a data expanding means 17 to output character data corresponding to respective dots constituting a character. Consequently, the storage capacity of the storage means 13 is reduced because the storage means 13 requires only the storage capacity to store compressed data obtained by compressing character data. Thus, unnecessary increase of the storage capacity of the storage means is prevented to express characters of high definition without raising the cost.

Title: Traverse method for thread
Inventor: BABA KENJI
IPC: B65H54/28
Filed: 1989-05-19
Abstract: PURPOSE:To make no acute angle turn which leaves the condition of a system as it is, but make the locus of the system constant so that a winding condition is made to be stabilized by flexing the system from the upstream system guide at the downstream system guide so as to guide the system to the width of a take-up traverse, thereby returning the system to the upstream guide position by system tension force with the system released from the downstream system guide when the system comes up to the width of the take-up traverse. CONSTITUTION:When an upstream system guide 14 enters into R1 return, a downstream system guide 14 flexes a system 20 from the upstream system system guide 14 in order to guide the system to the width of a take-up traverse. Then, when the system comes up to the width of the take-up traverse, an acute angle turn is made by means of role shearing wherein the center section of a winding ball is covered by the upstream system guide 14, and the both ends of the winding ball are covered by the downstream system guide 16 in such a way that the system 20 is released from the downstream system guide 16 in order to return it to the upstream system guide 14. Moreover, since the upstream system guide 14 holds the system at all times, there hardly exists fluctuation in thread locus after releasing is effected.

Title: Optical beam printer
Inventor: HONMA YOSHIFUMI
IPC: G03G15/04
Filed: 1983-07-15
Abstract: PURPOSE:To prevent an optical system from dirt by arranging plural dividing walls having slits forming an optical beam path and a dust removing box having a space for settling dust formed between the dividing walls on an optical beam projection port part of an exposure optical means. CONSTITUTION:The dust removing box 22 has opening parts for dust preventing slit plates on the surface side of a photosensitive drum 7A and the part between respective slit plates has a labyrinth structure having the comparatively large capacity of a dust space. To adhere fine powdery toner generated from a developing unit and floating around the surface of a photosensitive drum 7A to the surface of a cylindrical lens 8A, the fine powdery toner should be successively passed through the opening parts of the dust preventing slit plates on the dust removing box 22. Since the inner space of the dust removing box 22 formed between the slits is larger than these opening parts, an air flow rate in the box is reduced and the floating fine powdery toner is settled by its light weitht.

Filed: 1982-07-23
Abstract: PURPOSE:To obtain a desired copy image through a screen type image forming device by varying a bias voltage applied to a developing device according to whether line copying or gradation copying is performed. CONSTITUTION:The development bias voltage is applied to the developing sleeve 11 of the developing device 7. Then, the application of an AC bias voltage 13 or grounding 14 is selected with a changeover switch 12.

Title: Runner
Inventor: OONISHI SANETSUGU
IPC: F04D29/22
Filed: 1977-10-28
Abstract: PURPOSE: To reduce a maximum centrifugal stress generated at the root of a vane core plate and improve the reliability of a runner by forming a thick slope which increases in the direction from side plate to core plate, on the vane in the vicinity of the rear edge part of the runner.  
     CONSTITUTION: At the vane 3 part in which a maximum stress is generated, or between the position more than 2/3 apart in the radial direction from the central part of a runner and the rear edge part, a thick slope is formed which increases in the direction from a side plate 2 to a core plate 1 on the vane 3. This constitution allows a maximum centrifugal stress which is generated at the root part 3a of core plate 1 of the vane 3 to generate a bending moment at that part, and this bending moment is made uniform due to the thick slope at the root 3a of the vane 3. Thus, the maximum centrifugal stress generated at the root part 3a of the vane 3 can be reduced, and the strength of the vane can be maintained, without decreasing the fluid performance and fabrication efficiency.
