Title: Inversion prevention circuit
Inventor: KANEKO MASAYASU
IPC: H04N5/93
Filed: 1991-09-30
Abstract: PURPOSE:To improve the utilization ratio of an upper side-band and to well prevent an inversion phenomenon in an excellent S/N. CONSTITUTION:An FM signal YFM is supplied to an adder 12 and the output of the adder 12 is supplied to a limiter 13 having a non-linear gain. The output of the limiter 13 is supplied to a delay circuit 31 of taualpha/2 and the output of the limiter 13 is supplied to an adder 14 directly and via a delay circuit 15 of tauD. The output of the adder 14 is supplied to the adder 12 via an attenuator 16 to add it to the FM signal. When the FM signal level is sufficiently large, a sine filter having a peak frequency fc=1/2tauD is formed. By setting 'D' so that the fc can be the upper side-band, the utilization ratio of the upper side- band can be improved and resolution in demodulation can be improved. The smaller the FM signal level gets, the closer to fp=1/2(tauD+taualpha) the peak frequency becomes and the larger a boost operation becomes. By setting the 'taualpha'so that the fp can be near the maximum frequency displacement of a carrier wave, the side-band can be suppressed and the inversion phenomenon can well be prevented in an excellent S/N.

IPC: G01R31/317
Filed: 1989-09-27
Abstract: PURPOSE:To facilitate the measurement of the performance of an IC by adding a data-through function to each FF in an integrated circuit IC, and constituting multiple-stage delaying circuits. CONSTITUTION:A shift-mode input SFM for FF1-(n) is made to be 1 and a data-through input Thru is made to be 0. Then, the FF1-(n) are connected in series, and a scanning path is formed. Data are inputted P1 at the rise-up timing of a clock which is imparted to an input terminal P4. The required data are held in the FF1-(n). When the state is returned to a normal mode, various kinds of the diagnoses can be performed. When the input Thru is 1 and the input SFM is 0, the output of an OR circuit 5 becomes 1, and a master latch 3 and a slave latch 4 both become the through states. The D input is sent to the output Q or Q'. Therefore, the FF1-(n) can be made to be through. Thus other circuits can be diagnosed. When both the input SFM and Thru are made to be 1, the FF1-(n) are connected in series, and the part between the input terminal P1 and the output terminal P5 becomes a delay circuit having (n) stages. The error between the delay time and the expected value appears clearly. Therefore, the performance of the IC can be effectively measured.

Filed: 1994-09-20
Abstract: PURPOSE: To prevent the damage in a door or a wall by colliding a piston in a cylinder raised by engaging with door opening operation with a stop device, and preventing a door from opening with an angle exceeding the maximum angle. CONSTITUTION: When a door 7 is opened with an angle exceeding a specific angle, the upper end face of a piston 11 raised by engaging with the door 7 is brought into contact with the lower end of a compression coil spring 20. After that, rising operation of the piston 11 is damped with the elastic force, so that back check function is gradually operated to prevent rapid opening operation. Then, when the door 7 is opened with an angle exceeding the maximum allowable angle, the piston 11 raised by engaging with opening operation of the door 7 is collided with a projection 13A of the lower surface of a closing cover 13. In order to prevent the rising exceeding specific one of the piston 11, the door 7 is not opened with an angle exceeding the maximum angle.  By the constitution, even if the door is fanned by the wind or even if the door is opened with an angle exceeding the maximum allowable angle because of unexpected external force, the sudden opening of the door or the collision with a wall can be prevented.
