IPC: A63H27/00
Filed: 1994-08-22
Abstract: PURPOSE: To realize an accurate digital indication, by providing a revolution speed sensor on the output shaft of a rotary driving machine mounted on a model plane or the like and counting the output signals of the revolutional speed sensor for a specified time interval from a specified high-frequency signal generated out of a crystal oscillator and displaying the digital indication. CONSTITUTION: A specified high-frequency signal outputted from a crystal oscillator 15 during the engine driving of a model plane or the like is divided by a frequency divider 16 to input them in a counter controller 10 which counters the number of wave-form with about 0.6 times of a specified frequency outputted from the frequency divider 16. During the counting, the number of the pulse signals generated from the revolution speed sensor 11 is measured by a counter 12. The output pulse number of the revolution speed sensor 11 is displayed in digital on a liquid crystal indicator 13. Accordingly, the revolution number per 0.6sec. is shown in digital in the liquid crystal indicator 13 and the revolution number per one min. is obtained by multiplying the above figure by too.

Abstract: PURPOSE:To prevent wrong access by informing and identifying a specific area subjected to access within a data memory part. CONSTITUTION:Control information given from the outside is inputted to an external terminal 14 and a data processing part 13 decides the propriety of an identification number, write permission data and read permission data. The address of a data memory part 11 is controlled via an address control part 12 for a data writing or reading action.

Then sound of a prescribed frequency is outputted through a speaker 16. Thus it is possible to identify surely a wrong access given inadvertently to the area having the highest secrecy by setting previously the highest priority to said area.

Abstract: PURPOSE:To avoid the step-out of a wiring by obtaining a connecting hole whose sectional form is smooth, and improve the reliability of a device, by performing a weak anisotropic etching to form the connecting hole to connect the part between wirings. CONSTITUTION:On a first Al wiring 10, a plasma oxide film is grown as an interlayer insulating film 11.

Title: Signal switching device
Inventor: KOSAKE MINORU
IPC: G11B7/00
Filed: 1984-09-21
Abstract: PURPOSE:To perform signal switching without causing any crosstalk and to remove a pop noise securely in power-on operation by providing an element which forms a small-time constant discharging circuit composed of an AC coupling circuit and a control means which places a switching means in the 2nd switching state when the power source is turned on. CONSTITUTION:When a low-level muting signal is inputted from a muting signal generating circuit 83 for a specific time during power-on operation, drivers 82L and 82R are driven by NAND gate circuits 84L and 84R. When the power source is turned on, a resistance R2 is connected to a resistance R1 through mode changeover switches 76L and 76R in parallel so as to form the discharging circuit which has a time constant tau2 smaller than the time constant tau1 of the AC coupling circuit composed of a capacitor C and the resistance R1. A charge generated by the capacitor C is discharged principally by the resistance R2, so a pop noise generated in the power-on operation is removed completely in a short time without extending a convergence muting time.
