Title: Recording and/or reproducing device
Inventor: KOGA NOBUYUKI
IPC: G11B15/28
Filed: 1990-06-18
Abstract: PURPOSE:To contrive simplification and thin formation of the device and to prevent variations of the rotating speed of a flywheel by rotating a rotary disk body in contact with a rotary operation body of a rotary driving means and transmitting this rotation via an endless driving belt to the flywheel fitted with a capstan shaft. CONSTITUTION:The rotary operation body of a cylindrical motor 2 is brought into contact with a driven disk 15 of the rotary disk body to rotate this disk body. The disk 15 is controlled to be under a constant speed rotating operation by a rotation detecting means 16 and a control means 17, and the flywheels 7 and 8 to be rotatively operated are rotated at a constant speed even, in particular, when a vibration in a low frequency area and an impact are propagated from the exterior. Then, since the rotation of the above mentioned rotary disk body is propagated via the endless driving belt 18, the flywheels 7 and 8 are operated to rotate at low speed even when a vibration in a high frequency area and an impact are propagated from the exterior. Moreover, the flywheels 7 and 8 are thinned because of no rotation detecting means being fitted.

Title: Contact-type probe
Inventor: YOSHIDA KOICHI
IPC: G01R1/067
Filed: 1985-07-19
Abstract: PURPOSE:To enable measurements of many probes with a single unit of measuring instrument by incorporating a FET transistor (Tr) inside a connecting unit of the probe. CONSTITUTION:Allowing contact of a contacting unit 2a of a needle 2 with a test piece 13, a voltage is fixed by application to drain D and source S of the specified voltage. And, a gate G-source S voltage is changed. Namely, when a gate G-source S voltage is adjusted negative, a source S-drain D (channel resistance) is increased, causing drain D current drop. On the other hand, a high voltage of gate G opens the channel at a high (G) voltage allowing a current to flow from source S to drain D. Consequently, change of the (G) voltage causes a current change from source S to drain D. Namely, by an action of Tr 30 current control applied to the contacting unit 2 of the needle 2 become available, giving switching function to the probe itself. Thus, measuring signals of a large number of probes can be processed programmably.
