IPC: H04N5/74
Filed: 1989-04-28
Abstract: PURPOSE:To prevent a character color from not being displayed at all times by displaying comments, etc., on a tube surface with remaining beams if a tube surface display beam is cut off at the time of adjustment. CONSTITUTION:If one of the display beams for the primary colors is cut off and that is detected by a character signal generating circuit 13, a color selection signal indicates white instead of a specified color. Here, character signals of the three colors are generated by a control part 15 and a character signal generating circuit 16. When a character output mode wherein comments, etc., are displayed is entered, the cutoff is detected and it is judged which display beam is cut off. When there is the cut-off beam, data of the color selection signal corresponding to the comments, etc., is set together with a character and symbol selection signal and sent out to the circuit 13. Here, when one or two colors are cut off, a tricolor signal generating circuit 17 displays the character signals in three colors.

IPC: G06F13/28
Filed: 1986-05-16
Abstract: PURPOSE:To improve the processing capacity of a DMA transfer control circuit by starting continuously the DMA transfer just with a single start applied from a processor and with no subsequent intervention of the processor. CONSTITUTION:A DMA transfer control circuit 12 contains an FIFO which stores the head addresses of plural areas of a main memory MM8 and the number of transfer words of each head address, a control circuit which gives a writing action to the FIFO via a processor 7, a control circuit which reads the transfer addresses and the number of transfer words out of the FIFO and loads them into a transfer address counter and a transfer word number counter, and a control circuit which accepts the DMA start and produces the bus release request timing. Then the circuit 12 performs the control to finish the DMA transfer for the first time after the FIFO is empty by the FIFO monitor control. No interruption is produced to a processor before the transfer is through with all set transfer blocks although the processor is set before start of the DMA transfer. Thus the software control is simplified and the processing capacity is never deteriorated with a DMA transfer control circuit.

Abstract: PURPOSE: To transfer glass containers at a higher speed by providing such an arrangement that a side wall which defines pockets for receiving the glass containers is projected beyond the free outer end of an outer projecting wall at a completely extended position. CONSTITUTION: In case of displacement of a bottle 12 onto a cross conveyer across a transfer panel 16 in a pick-up mode, pockets 49 initiate its rotation when bottles 12 approach the transfer panel 16. When the center of each of the bottle 12 approaches the center line of the cross conveyer 14 so that the bottle 12 initiates movement across the transfer panel 16, a side wall 50 advances so as to set up a path of the bottle 12. When a part of the bottle 12 which is larger than a half part of bottle 12 rides on the cross conveyer 14, the bottle 12 rides on the cross conveyer 14. The side wall 50 continues it advance through a curved part while its engagement with the bottle is maintained, and accordingly, the bottle 12 is stabilized and completely transferred until it is conveyed to the cross conveyer 14 so as to pass by an end part of a rear wall 48.  With this arrangement, the conveyer 10 makes a certain angle to the cross conveyer 14 while it continues its motion, thereby it is possible to allow the rear wall 48 to pass by the bottle 12.

IPC: H01F37/00
Filed: 1984-05-31
Abstract: PURPOSE:To provide an inductor which reduces noise level by loading a required number of sheet coils to the integrally formed core. CONSTITUTION:Any type of core 10, for example, the integrated type or laminated type, may be employed. However, this core 10 should have a gap 12 within the loop but should not have the abutting portion unlike the conventional one. The sheet coil 11 is well known and it is obtained by forming a coil 14 to an insulated sheet 13. The sheet coil 11 provides a hole 15 and the specified number of coils are loaded through insertion from the gap 12. The laminated sheet coils 11 are spot-welded for mutual connection at the end portions of coil 14 in order to obtain the required inductance value. The inductor thus obtained is integrally formed without the abutting part at the core. Thereby, contact vibration of abutting part due to leakage magnetic flux can be eliminated and noise can intrinsically be reduced.
