Title: Flexible disk cartridge and motor for driving the disk
Inventor: OGATA MASAAKI
IPC: G11B19/20
Filed: 1995-02-08
Abstract: PURPOSE: To shorten the contact surface of a motor shaft by eliminating a bent erected part at the central hole of a media hub. CONSTITUTION: The erected part of the peripheral edge of the central hole 34 of a media hub is eliminated, and the thickness of the edge of the hole is made substantially equal to the thickness of the hub. A slight sag 37 by the annular plastic processing of the hub base side of the hub is formed instead of the roundness R. When the diameter of a shaft 42 is so set as to be slightly smaller than that of the hole 34 of the hub, the sag part 37 is positioned via the bent surface of the end, and the shaft 42 is inserted to the hole 34. As the result of no erected part, the shaft is shortened, and a motor is reduced in thickness.

Title: Abnormality display device for liquid level controller
Inventor: KOSAKA SHIGEO
IPC: G01F23/24
Filed: 1989-02-22
Abstract: PURPOSE:To decrease the capacity of a power unit by using an oscillation means which oscillates in a prescribed cycle to perform the display of abnormality of one of two tanks at the time of outputting from one of both sides, then the display of abnormality of the other tank at the time of outputting from the other side, respectively. CONSTITUTION:When the full water abnormality signals and the water reduction abnormality signals of one side tank 3 and the other side tank 5 are inputted from an abnormality detecting circuit 8, the corresponding contacts 12a - 12d are closed. As a result, a corresponding 1st TR 19 is turned on and at the same time the 2nd TR 22a and 22b are alternately turned on and off in a prescribed cycle in response to the working of an oscillation means 23. Thus the currents flow to the display devices 3a, 3b, 5a and 5b related to the TR 19, 22a and 22b respectively for execution of the display of abnormality. As a result, the current consumption is reduced down to the value equivalent to just one display device in a continuous energizing state despite the simultaneous input of abnormality signals of both tanks 3 and 5 since the currents flows alternately to the display devices 3a, 3b, 5a, 5b.
