Filed: 1992-02-27
Abstract: PURPOSE:To increase the operation speed of the mathematical logical operation unit (ALU) in arithmetic mode wherein a carry-out signal of addition, multiplication, etc., is generated by separating a latch clock which is supplied to a latch circuit into a low-order bit side and a high-order bit side. CONSTITUTION:The ALU enters an arithmetic mode of addition, multiplication, subtraction, AND, OR, or comparison selectively according to an instruction that a CPU sends, and processes data inputted from bus lines BUS0-BUSn through latch circuits Lat.0-Lat.n. This unit is equipped with 1st and 2nd buffers Buff.1 and Buff.2 and then performs the load separation of the latch clock PHIconsisting of low-order bits 0-(m) and high-order bits (m+1)-(n) to reduce the load on the low-order bits 0-(m). Consequently, when this is applied to, for example, 32-bit width ALU, the rising of a latch clock PHI consisting of about four low-order bits can be made high speed.

Title: Steel plate transferring device
Inventor: HIRAKAWA YOSHIHIRO
IPC: B65H3/60
Filed: 1980-03-31
Abstract: PURPOSE: To prevent the dislodging of the sucked and ascending steel plate and improve the safety of transfer by detaching the magnet type laminated layer separating member disposed on the side of the steel plates from the steel plate at the hoisting of the steel plate in separating and transferring the laminated steel plates, sheet by sheet.  
     CONSTITUTION: When a steel plate detecting element 8 abuts on the top surface of the steel plate 2 in the uppermost position, a vacuum pad 3 operates and sucks the steel plate 2 in the uppermost position. At this time, a laminated layer separating member 9 is in proximity to the side of the laminated steel plates 2 and separates one sheet of the steel plates 2 by the effect of magnet. When the vacuum pad 3 sucks one sheet of the steel plate 2, the 1st air cylinder 6 operates to hoist the steel plate 2 in the uppermost position; at the same time, the 2nd air cylinder 13 operates to retreat the member 9 and detach the same from the laminated steel plates 2. Thereby, the action of the magnetic suction force of the member 9 upon the ascending steel plate 2 is prevented, hence the steel plate 2 is transferred to the predetermined position without dislodging from the vacuum pad 3.

Title: Automatic welding machine
Inventor: TAKI MASAKAZU
IPC: B23Q35/13
Filed: 1983-03-14
Abstract: PURPOSE:To enable simultaneous welding while specifying a weld line in an automatic welding machine provided with a magnetic sensor that detects leakage flux generated from weld line gap by covering the sensor with a non-magnetic body. CONSTITUTION:Magnetic flux is generated in space when a magnetic body such as iron is arc welded. Out of this magnetic flux, that which goes out in the space across a weld line 2 gap is multiplied by relative permeability of an object 1 to be welded, and distribution of magnetic flux becomes strongest at the center of weld line. Accordingly, the weld line 2 can be specified by detecting the maximum place of distribution of magnetic flux by a magnetic sensor 9 attached to a welding torch 8. A large quantity of spatter is generated during welding. However, as the sensor 9 is covered with a sensor case 12 and a sensor case cover 121, the sensor 9 is not hit directly by the spatter 11.
