Title: Converter for satellite broadcast receiver
Inventor: KINOSHITA AKIRA
IPC: H01Q13/02
Filed: 1990-08-31
Abstract: PURPOSE:To shorten the length of a circular-linear polarized wave converter, and to shorten the overall length of the converter by constituting the circular- linear polarized wave converter of a specified metallic plate inserted into a waveguide at an angle of 45 deg. against the electric field vector of a desired linear polarized wave. CONSTITUTION:Only one metallic plate 11 is used, and it is inserted into the waveguide 2 at an angle of 45 deg. against the electric field vector of the desired linear polarized wave, and its electrical length 18 made equal to a quarter wavelength. Accordingly, as for a circular polarized wave supplied from a primary radiator 1, the phase of the polarized wave with the electric field vector component parallel with the metallic plate 11 is delayed by 90 deg. by the metallic plate 11, and at the edge of the metallic plate 11, two linear polarized waves become of the same phase, and the desired linear polarized wave is obtained. Thus, the length of the circular-linear polarized wave converter can be shortened without being influenced by the precision of the relative position of two metallic plates, and the total length of the converter incorporating it can be shortened.

Title: Electric current supplying circuit
Inventor: MATSUI KENJI
IPC: G05F3/26
Filed: 1983-12-08
Abstract: PURPOSE:To accurately obtain a desired electric current value, by connecting the back gate of an MOS type field effect transistor to the 2nd resistance which is connected with a reference electric potential. CONSTITUTION:Emitters of bipolar transistors (Tr) 23 and 22, whose bases are commonly connected, are connected with a power-supply voltage Vss through resistances 24 and 25, respectively. A constant-current output is taken out by connecting an MOS type field effect Tr21 between collectors of the Trs 23 and 22 and supplying the back gate 27 of the Tr21 from the high potential side A of the resistance 24. Therefore, since the voltage of the back gate electrode 27 of the MOS type field effect Tr21 becomes larger when a collector current Ic22 is large and the difference between the collector current Ic22 and another collector current Ic23 is small, the ON-resistance also becomes larger and even a weak error current can be corrected.

Title: Ultrasonic detector
Inventor: OKAMOTO MINEO
IPC: G01S7/52
Filed: 1991-09-13
Abstract: PURPOSE:To make it possible to reduce a delay in detection of an object by making an interval of transmission variable to be long or short in accordance with the degree of temperature, in a sphere not being affected by the multiple reflection of an ultrasonic wave by a background object. CONSTITUTION:A transmitter-receiver 1 being used for both transmission and reception and comprising an ultrasonic vibrator and others is employed. An ultrasonic wave is transmitted intermittently from this transmitter-receiver 1 and a reflected wave from an object to be detected is received. An interval of transmission of the ultrasonic wave transmitted from the transmitter-receiver 1 is determined by an integrating circuit 2 detecting temperature, a monostable multivibrator 3 and a switching circuit 4. Herein the circuit 2 starts an operation of integration simultaneously when a power source is made, and triggers the multivibrator 3 when an integration level reaches a certain potential. When the multivibrator 3 is triggered, the circuit 4 makes a charge of a capacitor constituting the circuit 2 be discharged and makes the circuit 2 restart the operation of integration. In other words, a period when the multi-vibrator 3 is triggered by an output of the circuit 2 produces the interval of transmission of the ultrasonic wave. According to this constitution, the interval of transmission can be varied in accordance with the temperature.
