Title: Drilling machine for reference hole in printed substrate
Inventor: NITTA TERUHISA
IPC: B23Q17/22
Filed: 1985-05-31
Abstract: PURPOSE:To machine a reference hole to be drilled correctly in the center of a copper mark, by actuating a servomotor to move a drill head, which provides an eddy current type position sensor, on the copper mark and detecting a boundary position while calculating the center position by a controller. CONSTITUTION:A drill head 14, providing an eddy current type position sensor 10 and a drill 12 to be arranged, is positioned in the upper of a printed substrate 30 and reciprocated in a direction X in the drawing through a table 18 by a servomotor 16. If the drill head passes on a copper mark 32, a machine, changing an output current detected by the sensor 10, stores coordinates of a boundary in a controller 24 by a pulse signal of the servomotor 16 to calculate the center coordinate position. Similarly the machine stores the coordinate position in a direction Y to be calculated by a signal from a servomotor 20. Next the machine, actuating the servomotors 16, 20 in accordance with coordinates adding to the above described coordinate position a space l between the drill 12 and the sensor 10 to be calculated, drills a reference hole in the center position of the copper mark.

Title: Forming method of abrasion-resistant layer
Inventor: KURODA KUNIO
IPC: B22D27/20
Filed: 1978-09-22
Abstract: PURPOSE: To selectively form abrasion-resistant layers on only the desired portions by delaying the freezing of the molten metal of the portions requiring abrasion- resistance of the products at the time of pressure casting light alloy in the product cavity of dies.  
     CONSTITUTION: Undulations are provided on the surface of the dies corresponding to the portions requiring abrasion resistance of the products and further the die temperature is made higher than other portions, thence light alloy such as Al or other is pressure cast. When the freezing of the molten metal of said portions is delayed intentionally, the unfrozen molten metal in which the silicon, copper, etc. of good abrasion resistance are concentrated in said portions in the final is extruded through pressure casting, whereby the abrasion resistance is formed. Here, mere provision of the foregoing undulations is good but the combined use of the same with temperature differences gives better effect.

Filed: 1984-06-08
Abstract: PURPOSE:To attain easy reset of addresses by providing a minor loop which is divided into long and short loops and connected by a data exchange gate, two auxiliary cap loops of the prescribed length and a replicate transfer gate which connects both auxiliary cap loops to a major line. CONSTITUTION:Two auxiliary cap loops 8 and 9 has a product of loop lengths equal to the length of a storage loop 1 and the difference of both loop lengths equal to 1 bit. A header is written at a position corresponding to the head of the data on the loop 1. The header writes 1 to each address of loops 8 and 9. The headers are set side by side, i.e., 1 and 1 at the replicate position when a rotary magnetic field of an integer multiple as much as the length of the loop 1 is applied. The head of the loop 1 is decided when the coincidence is obtained with the header after the reading is carried out a replicate transfer gate 4. In a data write mode it is possible to decide whether or not the header is set at the position of the gate 4 according to the contents of a counter which controls the address of the loop 1. As a result, the header is not lost due to the rewriting of the header.
