摘要:
A double superheterodyne tuner including a first and a second frequency converter and a bandpass filter, constituted of microstrip lines, wherein the substrate in which the bandpass filter is built is disposed back to back with the substrates in which the first and second frequency converters are constructed, with the substrate for the bandpass filter extending over the first and second frequency converters, so that a sufficient high-frequency isolation of circuit elements can be effected by the use of smaller shielding plates, the overall size can be reduced and a uniform grounded condition can be obtained.
摘要:
In a band pass filter of micro strip line structure, an input conductor, an output conductor, a first open end conductor and a second open end conductor are provided. The first and the second open end conductors are located opposite to the input and the output conductors forming narrow gaps between said open end conductors and said input and output conductors. The mutual inductance between the first and the second open end conductors is adjusted by selecting the width of the gap between the first and the second open end conductors.

A circuit body includes a flexible insulation sheet with an electric circuit pattern having wiring patterns and a temperature sensor arranged in the electric circuit pattern. The electric circuit pattern has a temperature-sensor connecting portion and a heat-concentrating pattern formed integrally with the temperature-sensor connecting portion so as to have a larger width than that of the wiring pattern. The temperature sensor is touched through the heat-concentrating pattern to an object to be measured. The wiring patterns and the heat-concentrating pattern are formed integrally on a primary surface of the insulation sheet by printing. An additional heat-concentrating pattern is further formed on a secondary surface of the insulation sheet at a position corresponding to the temperature-sensor connecting portion. The heat-concentrating patterns are bent integrally with the insulation sheet and touched to the object to be measured.

摘要:
The power window system moves a window glass in opening and closing directions in response to operation of an opening and closing instruction switch. The power window system includes a measurement device for obtaining an open degree of the window glass and a control device for controlling movement of the window glass in response to operation of the switch. The control device moves the window glass in the closing direction when an open degree obtained by the measurement device is not less than a predetermined degree and in the opening direction when the open degree is less than the predetermined degree.

摘要:
A current sensing circuit includes; a shunt resistor, on which a motor current is flown; a reference resistor which has a resistance value that is n times the shunt resistor; and a current following circuit. The current following circuit includes: a following current control circuit, which controls the following current and generates a first reference voltage; and a capacitor which generates a second reference voltage indicating an average value of the first reference voltage. A first comparator compares a third reference voltage higher than the first reference voltage with the second reference voltage, and outputs the current limitation control signal. A motor current sensing range expanding circuit expands a motor current sensing range by increasing a ratio of the current sensing circuit having the shunt resistor and the reference resistor.
