Title: Method of grinding
Inventor: KAWAMATA TAISUKE
IPC: B24B5/42
Filed: 1979-03-15
Abstract: PURPOSE: To raise the shape accuracy of a pin part in a short time and prevent the occurrence of an elliptic shape and a whirl, by causing a grindstone to undergo a step-like feed corresponding to an elliptic quantity produced during the halfway stoppage of the grindstone so that the grindstone rapidly cuts into the pin.  
     CONSTITUTION: After a wheel spindle stock is quickly fed forth to a point A, a grindstone grinds the shoulder of a workpiece at a shoulder grinding feed speed. The body of a rest is then quickly fed forth toward the workpiece and is engaged at a point C. After the pin part of the workpiece is cut to prescribed dimensions, the body of the rest is stopped (at a point D). The pin part is then moved toward the grindstone by an elastic force. When time set on a timer Tr2 has elapsed (at a point E), a quick cutting-in feed quantity Δl is set to cut the pin part. After the shape accuracy of the pin part is thus heightened, it is ground.

Filed: 1981-03-06
Abstract: PURPOSE:To detect a position accurately and suppress the variance of a working point, by detecting a minute movement of the position as a pressure change of a fluid in a position detecting device. CONSTITUTION:A piston 24 is driven by an operation bar 22 attached to a reciprocating driving rod 1. A pressurized fluid 25 is supplied to an auxiliary pilot 23.

Abstract: PURPOSE:To improve the workability of a complemental work by indicating the starting position of the complemental work and an unprocessed number when commodities are sold out on the way of sorting and complemented, in the case of the system in the title in a commodity distribution process. CONSTITUTION:For example, when commodities on a truck 1 in a zone B are sold out on the way of sorting due to the mistake of loaded number of commodity on the truck 1 and the like, a worker puts on the operation interruption key of a system controller 3 in the zone B so as to indicate the operating interruption. Thus, the controller 3 transmits a already processed data regarding the kind of commodity sold out to a relay machine, which arranges the processed data of the commodity. In the case of starting the complemental work, when the restart key of a controller 4 for retrieval is put on, the untreated data is indicated so that the commodities can be sent to the zone B. Then the normal processing is carried out. Therefore, the workability of the complemental work can be improved.

Title: Magnetic recording medium
Inventor: FUJITA MINORU
IPC: G11B5/80
Filed: 1988-02-16
Abstract: PURPOSE:To facilitate production and to improve security by providing a 1st magnetic pattern of the line width finer than 1mm and the 2nd magnetic pattern having >=1mm line width so that information can be recorded simply by changing the line width of the magnetic patterns. CONSTITUTION:A card 5 which has the 1st magnetic pattern 2b having the line width finer than 1mm and the 2nd magnetic pattern having >=1mm line width is carried. The magnetic flux changes when a magnetic head 6 passes above the magnetic ink patterns. The output voltage in a reverse direction is generated in the terminal of a detecting coil 62 at the beginning and terminating ends of the patterns. Whereas, this output voltage is much larger in the case of the pattern 2b finer than 1mm as compared to the case of the pattern 2a having >=1mm line width. The binary information of a low level is reproduced from the pattern 2a and of a high level from the pattern 2b by utilizing this phenomenon. The recording of the information is thus enabled simply by changing the line width and the production is facilitated. Since the thickness is uniform, the patterns are hardly visible and the security is improved.
