IPC: G11B7/26
Filed: 1986-09-24
Abstract: PURPOSE:To manufacture a medium without uneven thickness with a low cost by overlapping two disk bases to which paste layers are formed at a center hole and an outer circumference by screen print after a recording layer is formed and pressing and curing them. CONSTITUTION:The paste layers 3x, 4x are formed by the screen print along the inner and outer circumferences of the disk base 1a formed with the information recording layer 2a and having the center hole. The two bases 1a formed in such a manner are overlapped and pressed, the layers 3x, 4x are cured to form a spacer layer. THus, the layer 2a is used as the inside and the recording medium to which an inner space is provided between both the bases is formed. Since the layers 3x, 4x are formed by the screen print to eliminate the uneven thickness of the layer and the yield is improved. Thus, the medium having good balance without uneven thickness between the bases is manufactured with the low cost.

Title: Differential gear
Inventor: EZAKI SEIJI
IPC: F16H48/12
Filed: 1989-08-30
Abstract: PURPOSE:To prevent a differential gear from becoming large sized by forming a gear pump out of at least two mutually interlocked gears forming a gear mechanism and providing flow throttle means for giving a load to the gear pump. CONSTITUTION:In order to form a differential limiting means utilizing the rotation of first gears 8 on their axes, a gear pump is formed out of the first gears 8. A cross through recessed part 13 is formed at an intermediate plate 2b. An orifice 18a is formed at a discharge passage 18, so that high-pressure operating oil discharged from a discharge chamber receives resistance at the time of passing the orifice 18a, and this resistance becomes the load of the gear pump formed of the gears 8. When the rotational difference between shafts 11 is large and the rotating speed of the gears 8 is high, the resistance from the orifices 18a is increased and works in such a way as to block the rotation of the gears 8. The differential of a differential gear 1 is limited by this rotation blocking action. The differential limiting degree can be optionally adjusted by the size of the orifice 18a.
