Title: Power generation coil bobbin
Inventor: ODAJIMA MITSUO
IPC: H02K3/46
Filed: 1983-12-16
Abstract: PURPOSE:To avoid giving damage to the fine wirings during the coil forming process by changing the structure of die splitting surface of collar and bringing the burr generating position to the area not generating interference to the wiring portion. CONSTITUTION:The bottom surface 6a which is the die splitting surface when forming six collars of bobbin segments 3a, 3b formed by resin is formed to the surface (plane Z) parallel to the collar at the almost center of thick collar 6. Therefore, burrs 6b are generated, to the area extending to the inside from the side surface, at the collar 6 of three bobbins combining the bobbin segments 3a, 3b formed by resin during formation. Accordingly, on the occasion of forming the bobbin winding 4 consisting of the bobbin segments 3a, 3b formed by resin being engaged with a magnetic iron core 2, the winding 4a wound to the frame 5 near the inner surface of collar 6 of winding 4 and burrs 6b of collar 6 are not in contact each other because the burrs 6b are generated at the area extending inside from the inner surface of collar 6 of bobbin 3.

Title: Output spike voltage prevention circuit
Inventor: TATEHARA KENICHI
IPC: H03K17/16
Filed: 1988-09-21
Abstract: PURPOSE:To prevent an output spike voltage against a sharp change in an input voltage by applying specific connection to a diode and two transistors(TRs). CONSTITUTION:When an input voltage is, e.g., 5V, NPN TRs 15, 16 are turned on and a collector of the NPN TR 15 goes to an L level. In this case, an NPN TR 19 is turned off. If the input voltage changes up to 2V suddenly, the base potential of the NPN TR 15 is lowered, the collector potential starts increasing and the NPN TR 19 is turned on, then a current being a multiple of hFE of the base current flows through a resistor R4 from the power supply and the capacitor C1 as the charging current. The base potential of the NPN TR 15 rises suddenly by the said current thereby preventing the NPN TRs 15,16 from being turned on. Thus, the output spike voltage with respect to a rapid change in the input voltage is prevented.

IPC: G11B15/10
Filed: 1992-09-04
Abstract: PURPOSE:To stably maintain fixed tape running speed at a VTR for controlling reproducing speed corresponding to the turning speed of a dial. CONSTITUTION:A counter 3 counts pulse PFG from an FG2 for a fixed time. Count data DPC are supplied to a speed instruction part 5 and corresponding to the turning speed of a jog dial 1, the instructed speed is calculated by using a table showing relation between the turning speed of the dial 1 and the tape running speed.

When the turning speed of the dial 1 is changed by 2-3 rotations/second, the instructed speed comes to constant at one-fold speed, and the table is set so as to monotonously change the instructed speed at the other turning speed. Even when the turning speed of the dial 1 is fluctuated within the range of 2-3 rotations/second, the command CSP instructing one- fold speed is continuously supplied from the speed instruction part 5 to the tape running system 6, and the one-fold tape running speed is stably maintained.
