Inventor: MAKITA TSUYOSHI
IPC: F16H53/02
Filed: 1984-05-22
Abstract: PURPOSE:To manufacture the titled cam shaft equipped with porosity for an oil pit at the circular part of a cam base by leaving the casting surface of the circular part of the cam base of the cast cam shaft intact, and remelting and hardening directly the casting surface. CONSTITUTION:A cam top part 4 and a cam lift part 3 of a cam part 1 provided to a cast cam shaft is roughly ground by a cam grinder to obtain a roughly- ground surface 6, and the circular part 2 of the cam base is not ground and left intact as a casting surface 5. The cam part 1 is preheated to about 300 deg.C, and rotated in the direction as shown by the white arrow (a). A plasma torch 11 is reciprocated and vibrated in the directions as shown by the arrows (b) and (c). Consequently, the torch is allowed to follow a zigzag course 7 from a start point 8 on the roughly-ground surface 6 to a finish point 9 on the casting surface 5, and the remelting and hardening is carried out. By said process, porosity for an oil pit can be formed on the circular part of the cam base simultaneously with the remelting and hardening of the cam surfaces 5 and 6.

Abstract: PURPOSE: To control a device so that a beam spot will be constant as small as possible in recording while it is a little bit larger in reproducing, by providing two kinds of methods of detecting a distance between a condenser lens and recording medium.  
     CONSTITUTION: Light reflected by information track 13 of recording medium 12 is passed through condenser lens 10 and then detected by photo detectors 17 and 18, and 15 and 16 for focal-distance control. In order to equalize the quantities of detected light of photo detectors 17 and 18, condenser lens 10 is vertically moved, thereby keeping a light spot constant as small as possible in recording. In reproducing, change-over switch 23 is switched to supply an output difference between photo detectors 15 and 16 to condenser lens control circuit 31 via differential amplifier 23, so that the light spot will be a little bit larger than that in recording. Photo detectors 19 and 20 make comparison between respective quantities of light to allow the beam spot to scan on information track 13 accurately.

Title: Countermeasure method for power failure of magnetic tape unit
Inventor: OOTSUKA TETSUO
IPC: G06F11/00
Filed: 1978-08-28
Abstract: PURPOSE: To cope with a power failure easily and adequately by wirting data, block by block, on a magnetic tape and by controlling a magnetic tape unit on the basis of the number of stored blocks after recovery from the power failure.  
     CONSTITUTION: Once the address of RAM2 is assigned by CPU1. read data from RAM2 stored in buffer 4 are recorded, block by block, on cassette tape 6. On writing a unit block, CPU1 rewrites the contents of counter B by reading out the contents of block counter B of RAM2 and then by adding [1], so that the number of  blocks recorded on tape 6 will be stored in counter B. When a power failure occurs  and a power signal at the time of its recovery is applied, CPU1 reruns tape 6 after  rewinding it until its initial point via decoder 7 to read a block right before the final  block on the basis of the memory contents of counter BC and then erses the contents of tape 6, thereby restarting writing operation from the initial positopm of  the erased part.
