Title: Error detection circuit
Inventor: OKUYA TOKUNORI
IPC: G06F12/16
Filed: 1986-03-07
Abstract: PURPOSE:To prevent the transformation of data that is caused by a trouble of a set signal generating circuit by using a circuit which checks whether a set signal is outputted or not and decides the contents of a register are erroneous if no set signal is outputted. CONSTITUTION:The information delivered from a central processing unit CPU1 is outputted to the 1st register 3 via a signal line 3'. The register 3 stores said information when the output is received from a reset signal generating circuit 2 which is driven by the action command signal supplied from the CPU1. The output of the circuit 2 is also set to the 2nd register 8 which is updated in the system clock cycle. A check circuit 40 outputs an error signal if the register 8 has no set signal in a check mode of the contents of the register 3. Thus the error signal is outputted even in such a case where the circuit 2 has a trouble and outputs no set signal. In such a way, the transformation of data is prevented.

IPC: G06F3/06
Filed: 1979-04-25
Abstract: PURPOSE: To shorten the maximum time and mean time of transfer by shortening the time of access, even if it takes a long time, by dividing the transfer into two without remodeling specially the main body of a magnetic memory unit.  
     CONSTITUTION: When transfer is requested, a transfer start address is stored in sector register 7 and track register 8 via input-output interface 12 and under transfer-request halving control 13, the 1st transfer start address is generated being divided into two and stored in selector register 7a and track register 8a.

Title: Communication system for home control system
Inventor: IWATSUBO RIEKO
IPC: H04L12/40
Filed: 1989-03-02
Abstract: PURPOSE:To attain sure transmission and reception of a data by sending a reception reject frame to a sender terminal equipment from a buffer memory when a data is further sent to a terminal equipment whose reception reaches an allowable limit. CONSTITUTION:A telecontroller 1, a house keeping controller 2 and a room controller 3 as plural terminal equipments are connected through a common home bus 4. If a capacity of a buffer memory of a terminal equipment is occupied, when a data is received from other terminal equipment with higher transmission priority than the former terminal equipment, a reception reject frame is sent to the data sender to stop the transmission from the other terminal equipment. When the reception buffer is idle, a transmission enable frame is sent to the sender terminal equipment to allow the terminal equipment to send the data again. Thus, a disadvantage of the sent data overflowed from the buffer and lost without any compensation is avoided and the reliability of communication is enhanced.

Title: Vibrating conveyor
Inventor: NAGAO YUUJI
IPC: B65G27/28
Filed: 1982-03-29
Abstract: PURPOSE:To reduce the height of a whole conveyor, by a method wherein, in a vibrating conveyor for bulky material, two rotary shafts, whereto two each unbalancing weights are secured respectively, are located within a common surface paralleling a direction in which the counterweights extend. CONSTITUTION:Through running of a motor 16, a rotary shaft 12 through a belt 20 and a rotary shaft 13 through gears 21 and 22 are turned in a reverse direction to each other and at the same speed, and directions F of their respective centrifugal forces of unbalancing weights 23, 24 and 25, 26 are alternately brought to a reverse and a forward direction. In this case, a moment Fl is produced in the case of a distance (l) between the rotary shafts 12 and 13, and is exerted on a counterweight 3 and a trough 1. The moment of inertia, however, is sufficiently large and is prevented from exercising an influence on vibration, and the two rotary shafts 12 and 13 are located within a surface in a direction in which the weight 3 extends. This causes the trough to provide a linear vibration, which results in being capable of reducing the height of a whole conveyor to the minimum.
