Title: Video signal synthesizing circuit for monitor television
Inventor: KUBOTA SUSUMU
IPC: H04N7/18
Filed: 1986-03-07
Abstract: PURPOSE:To extremely easily attain the color modulation of a color video signal by adding to a black-and-white video signal a pre-color burst wave signal at the time of synthesizing the said two signals together. CONSTITUTION:A composite video signal 300 is mixed with a color burst signal generated in a monitor television. Even in case when a black-and-white video signal 100 is inputted, the color modulation of color pattern can easily be executed by using the pre-color burst wave signal. A color modulation circuit 40 has a pattern generating circuit 42 in itself, and outputs color patterns of the various indicator information of a vehicle and others. A color pattern signal 400 that is already color-modulated, is supplied to one input terminal 62a of a mixer 62. To the other input terminal 62b of the mixer 62, the above said composite video signal 300 is supplied. By optionally controlling the switching by means of an extraction pulse signal YS, a picture generated by color pattern signals 400 in which signals 300 are inserted can be obtained.

Title: Semiconductor laser
Inventor: KOTAKI YUJI
IPC: H01S5/042
Filed: 1988-03-02
Abstract: PURPOSE:To increase the modulation upper limit frequency and to level the degree of modula tion for increasing modulation characteristics, by establishing a phase adjustment region to change frequency by carrier injection and a frequency modulation area to change frequency by application of reverse-biase voltage. CONSTITUTION:In a light source of an FSK optical communication system, a phase adjustment region P and a frequency modulation region F are established. The frequency modulation region F changes a refractive index of a wave guide layer by application of reverse-biased voltage Vf and then changes frequency by the variation of the refractive index. In other words, the frequency modulation region is for modulating frequency using electrooptic effects. In this region, modulation characteristics depend only on the time constant of the RC product. The smaller the time constant gets, the higher the modulation upper limit frequency becomes over 10GHz. Therefore, the degree of modulation is leveled. Since variation of the refractive index is small in the frequency modulation region F, the variation width of wave length gets small if this region is completely replaced with a phase adjustment region. Because of this reason, a wide wave length variation phase adjustment region P is also established. By this, the modulation upper limit frequency increases, the degree of modulation becomes leveled, a wide variation of wave length is available and modulation characteristics is im proved.

Abstract: PURPOSE:To reduce a size and prevent erroneous operation due to the fluctuation of a liquid level or the like, by placing an ultrasonic oscillator at a prescribed level in a liquid tank and connecting an oscillation circuit to the ultrasonic oscillator to build a detection unit. CONSTITUTION:An ultrasonic oscillator 2 such as a piezoelectric oscillator is placed at a prescribed level in a liquid tank 1 and connected to an oscillation circuit 3 and the capacitor 5a of an oscillation output detection circuit 5. The oscillation 3 is so set that its impedance matching becomes proper and oscillation is performed when the oscillator 2 vibrates. The output of the detection circuit 5 is applied to a switching circuit 7 through a wave detection circuit 6 to control a warning lamp 8. When the level of a liquid falls to a position 1b, the oscillator 2 is exposed out of the liquid and starts vibration. At that time, the oscillation circuit 3 generates an oscillation output and the warning lamp 8 is lighted on through the wave detection circuit 5, the switching circuit 7, etc. This results in reducing a size and preventing wrong operation due to the fluctuation in the level of the liquid or the like.

Abstract: PURPOSE:To prevent the malfunction of an equipment provided with IR remote controller and the unoperation of a remote controller by producing a wave length selective IR reflecting film on the surface of the light transmitting portion of the envelope of a lamp. CONSTITUTION:A lamp is constructed with an envelope attached with a light transmissive globe 3 and a double U type luminous tube 5 supported at both ends and an electronic stabilizer 6 consisting of a high frequency inverter.

Abstract: PURPOSE:To reduce the number of elements, etc. constituting a main distributing frame (MDF) line and to reduce a space by making it possible to separate the pin connection parts of terminal blocks connecting inside lines and outside lines and performing bracketing. CONSTITUTION:Each pair of lines A and B of outside lines 50 and 50' is directly fixed and connected to pins 53 and 53' of slit-shaped terminal blocks 52 and 52' (fixed members) arranged fixedly on a printed board 51. Connectors (movable members) 54 and 54' are attached to pins 53 and 53' freely attachably and detachably. Inside lines 60 and 60' are connected to connectors 54 and 54' which can be moved to the printed board 51. Since fixed members and movable members connected freely attachably and detachably are connected directly in such a manner, the bracketing function is performed with two members. Movable members such as connectors or the like are interchanged to change wiring easily in a place where the MDF is installed. Bracketing is made more easy than a bridge clip having moving members as connectors.
