Title: Radio-wave reflection system
Inventor: ONOUE MORIO
IPC: G01S13/75
Filed: 1980-08-28
Abstract: PURPOSE:To transmit various kind of information besides information showing that where is a body at a reflection point, by constituting to vary the reflectivity of a reflecting plate according to the information to be transmitted. CONSTITUTION:For example, when an input signal to an input circuit 6 is a velocity signal (a) of a vessel, etc., the velocity signal (a) is encoded by an encoding circuit 5 and passed through a waveform shaping circuit 4 and a modulator 3 to turn on and off a reflecting plate 2. If a pulse wave of a radar arrives as shown by an arrow A, when it is modulated by the signal (a), a reflected radio wave is code- modulation in the form of the encoded signal (a). For this purpose, waveform shaping is performed after the detection of rader-side receiver through a holding circuit fitted with reset peak or a low-pass filter to reproduce a wave, modulated at a reflection terminal side, at the rader side. Thereby transmitting the speed signal (a) to the rader side. Thus, various kind of information are transmitted in addition to information showing that there is a body at the reflection point.

Title: Single-phase three-wire circuit breaker
Inventor: TOYAMA HIROYUKI
IPC: H02H3/34
Filed: 1995-04-19
Abstract: PURPOSE: To confirm the operation of the single-phase three-wire neutral line open phase protective function of a circuit breaker easily by a method wherein, when a detecting circuit detects a voltage exceeding a predetermined value, a thyristor is turned on by an output signal from the detecting circuit and, accordingly, a trip coil is excited and contacts are tripped by the excitation. CONSTITUTION: An overvoltage monitoring circuit and a test circuit 4 are connected to a single-phase three-wire system line 1. A test switch TS1 is closed and a current applied to the test circuit 4 is superposed on a current which is applied to the overvoltage monitoring circuit which monitors an overvoltage induced by the open phase of a neutral line N. As a result, a current which is applied to a second voltage dividing resistor R2 which is a fixed resistor is increased and hence the voltage between both terminals of the resistor R2 exceeds a predetermined value. This phenomenon is detected by a detecting circuit 3 and a thyristor SCR1 is turned on by a signal from the detecting circuit 3 and, accordingly, a trip coil TC1 is excited to trip contacts 5 and the operation of the protective function is confirmed.  It is to be noted that even if an overvoltage is applied by the open phase, a circuit breaker never fails to operate.

Filed: 1990-05-10
Abstract: PURPOSE:To form a super-miniaturized voltage controlled oscillator by varying an amplification factor of two amplification factor variable amplifiers in response to the control voltage and inverting the phase of its output signal. CONSTITUTION:When a level at a control terminal 20 is higher than a level of a control terminal 21, a differential voltage whose phase is 0 deg. is generated between inputs of a differential amplifier 11 and as the difference of the level at the control terminals 20, 21 gets smaller, the absolute value of the control voltage is made zero. Moreover, when the level of the control terminal 20 is lower than the level of the control terminal 21, a differential voltage whose phase is 180 deg. is generated and the absolute value of the control voltage is increased as the difference of the level at the control terminals 20, 21 is increased. Thus, the amplification factor of the 1st amplification factor variable amplifier is changed in response to the control voltage fed between the control terminals 20, 21 and the phase of the output signal is inverted.

Filed: 1990-05-09
Abstract: PURPOSE:To safely view an image with eyes by arranging a transparent filter plate which absorbs ultraviolet rays on the side of a phosphor screen which is viewed with eyes. CONSTITUTION:When the achromatic transparent or the chromatic transparent filter plate 3 which absorbs the ultraviolet rays is provided between the phosphor screen 2 and a view 4, light which is projected by a laser and whose wavelength is <= 380nm is entirely absorbed and intercepted. As the result, the viewer 4 directly views only a flourescent image which is radiated from the screen 2 and whose wavelength is >= 420nm. Since the fluorescence is not the light having high directivity and high energy density such as the ultraviolet rays laser light but it is diffused light, danger that the eyes of the viewer are stimulated is entirely eliminated. Thus, the viewer safely views the image with eyes.
