Inventor: NATHAN GUY
IPC: H04H20/84
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To perform stereophonic signal broadcasting that has a digital compact disk type quality by converting a compressed signal in a file that represents a compact disk type acoustic digital into a serial signal which is sent to a quadrature phase modulator circuit by every plural packets and sending a signal from the quadrature phase modulator circuit to an indoor feeding network. SOLUTION: A transmitter 10 and a receiver 11 are connected to a feeding network of a wire 13. A quadrature phase modulator circut 101 of the transmitter 10 performs quadrature phase modulation of data packets P1 and P2 which represent digital information converted into parallel-serial from a microcontroller 102 and piles up them on a sector of an alternating current signal through a 2nd transformer 109. The receiver 11 demodulates the data packets and outputs them to a speaker HP. Consequently, it is possible to install various speaker at various places, while supplying a signal of the same phase of the feeding network to which the transmitter 10 is connected to the speaker HP.

Title: Discriminating device for rotational direction of motor
Inventor: IMAZEKI TAKASHI
IPC: G01P13/04
Filed: 1985-12-06
Abstract: PURPOSE:To decide the rotational direction of a motor invariably accurately by holding the rotational direction when the rotary speed of the motor reaches a specific speed as a rotating direction decision signal. CONSTITUTION:When the motor 1 rotates, a pulse P1 from a pulse generator 5 is passed through an F/V converter 9 and compared with a reference voltage Vr by comparators 13 and 15. The voltage Vr is set nearly equal to the output voltage of the converter 9 when the motor 1 begins to rotate, so the output voltage of the converter 9 rises above the voltage Vr and the output of the comparator 13 varies to a high level. Consequently, the leading signal of the output voltage of the comparator 13 is applied to the trigger input of an FF 11, which latches the low-level output of a D type FF 3 and outputs the same low-level signal from its output Q. This low-level output signal indicates the rotational direction of the motor 1 and is latched by the FF 11 at its leading and held latched until the motor 1 stops rotation, so the rotational direction is discriminated invariably accurately even if a noise is mixed in the pulse from the pulse.

Consequently, the alkali or alkaline- earth metal ion, etc., as the volatile component in forming are fixed. Further, since only the outermost surface is nitrided, a desired optical characteristic is maintained by the internal glass. A glass material (e.g. phosphatic glass blank) is set on a fixing jig 10, and then an airtight chamber 3 is evacuated. The chamber is flushed with gaseous Ar, then gaseous nitrogen is introduced into an ionization chamber 5 to a specified gas pressure, a voltage is impressed on a grid 7 to draw out an ion beam, and the glass blank is irradiated with the beam.
