Title: Transmitting system of service sound
Inventor: HIYOUDOU WATARU
IPC: H04M19/02
Filed: 1981-06-15
Abstract: PURPOSE:To supply a service sound without imparing the economical properties, by connecting both the transmission and reception channels to the same terminal and controlling the ringing tone produced by the above-mentioned connection to transmit the ringing tone to the terminal. CONSTITUTION:A central controller CPU detects a telephone TEL whose receiver hooked off for a long period while supervising the working state of the TEL via a subscriber control circuit LC. In such case, the controller CPU gives an indication to a channel network controller CM to control a digital channel network DNW as well as to connect a transmission channel terminal TSi to a reception channel terminal TRi for the TEL. As a result, a loop-shaped channel including a talking level control circuit PADi is connected to the TEL via the circuit LC, and the CPU controls the circuit PADi so that a voice signal like the indoor noise, etc. that is given from the transmitter of the TEL produces a ringing tone of a high level by the above-mentioned loop channel. The ringing tone of a high level is transmitted to the TEL via the LC to arouse the attention of a subscriber.

Title: Ion detection device
Inventor: ASO YUJI
IPC: G01R29/24
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To provide an ion detection device that has an improved capacity for detecting ions, can detect ions reliably, and can examine a detection result easily. SOLUTION: When a negative charge is collected from a negative ion in atmosphere by a collection electrode 11, a voltage with the side of a ground electrode 15 being positive is applied between the collection electrode 11 and the ground electrode 15. A gate G is biased to a positive potential against a source S, so that an FET 13 is allowed to conduct current and an electricity is fed from a DC power supply 17 to an LED 19, thus lighting up the LED 19. The FET 13 is allowed to conduct electricity by applying a relatively low bias voltage between the gate G and the source S, thus detecting the negative ion even if the concentration of the negative ion in atmosphere is low. When a positive ion is collected at the collection electrode 11, an area between the gate G and the source S is inversely biased, thus preventing the FET 13 from conducting current and preventing the positive ion from being detected. A light- emitting diode 19 allows an ON state to be checked easily even in daylight and, if required, the light-emitting diode with a color of a high contrast against room light to be selected.

Title: Spread spectrum direct demodulator
Inventor: NAWA TOSHIHIKO
IPC: H04B1/7085
Filed: 1994-04-28
Abstract: PURPOSE:To realize accurately the detection of a phase locking or a pseudo locking by sampling a count value of a 1st counter circuit with a signal obtained through the comparison between an output of a square sum circuit and a prescribed value so as to quicken phase locking. CONSTITUTION:When phase synchronization is established, a phase of an output pulse of a 1st comparator circuit 12a is the same as a phase of a carry of a 1st counter circuit 11a, and when the count value is sampled by an output of a 1st comparator circuit 12a, the sampled value is '0'. Thus, a 2nd comparator circuit 12b compares the reference value '0' with an output of a 4th S/H circuit 7d and provides an output of a pulse indicating phase locking when they are coincident. Then a protection circuit 13a discriminates the establishment of phase locking when a prescribed number of output pulses of the 2nd comparator circuit 12b is counted. The signal changes from an H level to an L level when the phase locking is established, for example and changes from an L level to an H level when run-locking is settled and whether or not the phase locking is established is discriminated by extracting the level change externally.

Title: Input signal latching circuit
Inventor: YAMAMOTO SEIJI
IPC: H03K3/037
Filed: 1995-04-18
Abstract: PURPOSE: To attain normal latching in the case where an input signal is asynchronous with a clock signal by selecting a clock signal or a delayed clock signal in accordance with the phase difference between the input signal and the clock signal. CONSTITUTION: A phase comparing clock generating circuit 3 divides the frequency of a clock signal CLK and generates a signal A having an period almost equal to that of an input signal IN. Then a phase comparator 4 detects a phase difference between the signals IN, A and a phase difference judging circuit 1 compares the phase difference with a previously determined set value. When the phase difference is less than the set value, a delay circuit 2 delays the signal IN by prescribed time and a selector 5 selects the signal CLK or the delayed signal CLK based upon an output B from the circuit 1 and outputs the selected signal to an RF 6 as a signal C. The signal IN is latched by the signal C and outputted as an output signal OUT. Thereby even when the rise time of the signal IN is simultaneous with that of the signal CLK, the signal IN can be normally latched.
