Title: Memory controller
Inventor: YAMADA IKUO
IPC: G06F12/04
Filed: 1988-12-08
Abstract: PURPOSE:To reduce the quantity of hardware by holding a request address, which is transferred to a main memory, to the main memory as it is at the time of the first reading of partial writing. CONSTITUTION:A partial writing request code buffer 31 inputs an operation instruction and a band instruction that a partial writing request is passed through a check in a busy check circuit 13 and housed to a request code register 22. Since the partial writing request is decomposed to the two phases of reading and writing after merging and executed, the buffer 31 holds the instruction inputted until the time of writing. A main memory bank set signal generating circuit 32 decides the request bank of the request and generates a set signal to banks 0-3. An address set signal goes to 1 only at the time of full writing 8-byte and 16-byte reading and the first reading of the partial writing and the signal does not go to 1 at the time of full writing after partial writing. Thus, at the time of partial writing, it is not necessary to carry around a request address.

Abstract: PURPOSE:To obtain the display device which has a dust dumping display function corresponding to actual use and whose efficiency of suction work does not drop, and also, to provide a rugged part in a cylinder by forming plural different spring constant parts in a coil spring for energing to the open air side a piston inserted to be freely slidable into the cylinder. CONSTITUTION:When dust is not scavenged into a dust collection bag, a piston 40 is held in a prescribed position by a coil spring 50, and a light emission diode 21a is turned on. When dust is scavenged into the dust collection chamber and clogging starts, the piston 40 moves to an opening 30b side against the spring 50. Since a spring constant of the spring part (a) is small, the piston 40 moves quickly and the spring part (a) goes to a closely adhering state, reaches the vicinity of the lead switch 31, the lead switch 31 is turned on by a magnet 44 and a light emission diode 22a is turned on. When clogging advances, the piston 40 further moves the opening 30b side, but since a spring constant of a spring part (b) is large, the piston 40 moves slowly together with clogging and reaches the vicinity of a lead switch 32, and a light emission diode 23a is turned on.

Abstract: PURPOSE:To prevent blocking-up of balls by providing in the subject device a discharging member whereby the ball remaining inside a ball-holding part in a rotary holder can be forcibly discharged. CONSTITUTION:Pachinko balls B are arranged and sent on a sending way, and the balls shifted into the inside of the sending way are retained in a retainer 20. A rotary holder 12 having a ball-holding part 13 therein is turned by a motor 10 for driving its turning, and in the middle of the turning of the rotary holder 12, the first one of the balls retained in the retainer 20 is picked up and is supplied to the inside of the ball-holding part 13 in the rotary holder 12, and thus the balls are separated and supplied one by one. At this time, when the ball has remained inside the ball-holding part 13 without being shot for any cause, the ball remaining inside the ball-holding part 13 in the rotary holder 12 is allowed to abut on a discharging member 21 and is forcibly discharged outside. Therefore, even if such the condition that any of the balls is not shot is caused, the operation of separating and supplying the next ball can be surely performed under the condition that the inside of the ball-holding part 13 is empty, and blocking-up of the balls in a process of separating the balls can be prevented.
