Title: Solid-state image pickup element
Inventor: ATSUTA YASUSHI
IPC: G02B27/10
Filed: 1990-03-22
Abstract: PURPOSE:To suppress a false signal and to cut infrared rays at low cost by providing an optical low-pass filter between the emitting surface of green and red light flux and a solid-state image pickup element while including blue light flux out of the prism emitting surfaces of the respective light flux in three primary colors. CONSTITUTION:Optical low-pass filters 30 and 32 and infrared cut filters 31 and 33 are provided at the back of a color separation prism 20 just before solid-state image pickup elements 34 and 36. The respective filters are handled not as three sets but as two sets and although conventional one set is changed to the two sets, the total area can be decreased by half by increasing an area per filter to be about 1/4. In such a case, for the blue signal, the contribution rate to a luminance signal (Y signal) is made minimum and an influence to resolution is small. Therefore, the optical low-pass filter for the blue light flux is omitted. Thus, the satisfactory picture quality suppressing the false signal can be obtained at much lower cost and it is effective for simplifying a solid- state image pickup device.

Title: Automatic gain controlling amplifier
Inventor: OKAMOTO SHINGO
IPC: H03G3/30
Filed: 1988-03-29
Abstract: PURPOSE:To eliminate the interference waves superposed upon received signals so as to fix the level of transmission signals by correlating the received signals with the output signal of am amplifier in accordance with generated reference signals. CONSTITUTION:The level of reference signals generated from a reference signal generating circuit 4 is fixed and the output level voltage of a correlator 5 appears with a frequency and the phase difference between the reference signals and transmitting signals. When the output level voltage is passed through a low-pass filter, low-frequency signals having a voltage which can cope with the level variation of the transmitting signals can be fetched. On the other hand, the amplitude and phase of the low-frequency signals vary irrespective of the correlation between interference waves and the reference signals and, after passing through the low-pass filter, the output voltage of the correlator 5 becomes zero. Therefore, low-frequency signals which are the transmitting signals are obtained from the output of an amplifier 3. The voltage applied across the amplifier 3 when these low-frequency signals are detected by means of a detector 6 and passed through a loop filter 7 is the voltage corresponding to the transmitting signals. Accordingly, the transmitting signal level of the amplifier 3 is fixed and the aimed automatic gain control is performed.

Title: Phased array radar equipment
Inventor: YOKOYAMA HIROSHI
IPC: G01S7/02
Filed: 1989-03-28
Abstract: PURPOSE:To suppress an unnecessary signal by providing a switch, which selects plural switch matrixes to connect them to column arrays, and a means which sets operating frequencies of plural transmission/reception parts to values different from one another. CONSTITUTION:When the range of column arrays 1-1 to 1-8 is connected to a switch matrix 3-1 and column arrays 1-17 to 1-24 out of 24 column arrays are connected to a switch matrix 3-2, three beams are simultaneously formed. When three beams are operated with frequencies different from one another in this case, only the signal having the operating frequency set to a transmission/reception part is permitted to pass through but signals having the other operating frequencies are stopped by providing a band-pass filter in the reception input of the transmission/reception part, and therefore, reception signals of three beams are separated from one another, and consequently, a false target or an unnecessary signal are suppressed.

Abstract: PROBLEM TO BE SOLVED: To improve reliability of action without cooling thermally expanded liquid having a high temperature by a low temperature refrigerant, by forming a space part in which the refrigerant is entered between a cover plate and a heat insulating chamber by a diaphragm, and heating thermally expanded liquid closing and filled into the pressure producing space part of the heat insulating chamber by a disk. SOLUTION: In this valve, a cover plate 22 that an inflow opening 22a and an exhaust opening 22b are formed on both its sides is fixed on the upper surface of a base plate 21. A diaphragm 26 forms a space part 22c into which a refrigerant is filled between the cover plate 22 and a heat insulating chamber 25, and a disk 28 is fixed on the lower surface of the heat insulating chamber 25 so as to tightly close a pressure producing space part 25a. Heating means is arranged which heats thermally expanded liquid 24 filled into this pressure producing space part 25a. The thermally expanded liquid 24 suppresses thermally exchanging action by minimizing a part directly brought into contact with the refrigerant through the diaphragm 26. Therefore, the diaphragm 26 is expanded to the exhaust opening 22b side by the expanding action of the thermally expanded liquid 24, and an amount of a liquid refrigerant to be exhausted can be reduced.

A meteorological parameter calculation circuit 15 calculates meteorological parameter such as rainfall and indicates information concerning the meteorology on a display.  In this manner, an averaging processing is applied to the cloud water amount M with an averaging circuit 12 and so the error variance included in the cloud water amount M is reduced and thus the effect of noise and measurement error generated in the step to the two-cycle measuring method execution circuit 11 can be mitigated.
