Abstract: PURPOSE:To realize a control apparatus for charging generator for vehicle which prevents errornous alarm due to increase of output from a charging generator, issues an alarm when a terminal of a charging generator or voltage detecting terminal is disconnected and also automatically sets an output voltage of the charging generator to a value near the normal value. CONSTITUTION:Under the normal condition, an output V75a of a first voltage dividing circuit 75 is larger than an output V76a of a second voltage dividing circuit 76, making conductive a transistor 771.

The comparator 80 compares the reference voltage with a voltage 75a to supply an output signal to a transistor 71 in view of controlling a voltage of the terminal S to a preset voltage. When the voltage detecting terminal or output terminal is disconnected, voltage 75a becomes smaller than the voltage 76a (75a<76a) and an output 78x becomes 'L' level, the transistor 771 becomes nonconductive, a signal 76a is output from the selection circuit 79 and a voltage of the output terminal B becomes equal to the preset voltage. An output 78x of the comparator 78 becomes 'L' level for the period longer than the constant period, making conductive a delay circuit 82 and lighting a display lamp 6.

Filed: 1978-05-22
Abstract: PURPOSE: To improve a contrast by reducing the external-light reflection of a fluorescent screen, by reinforcing a fluorescent substance in terms of characteristics of suppressing the reflection of external light.  
     CONSTITUTION: A red-light-emitting component fluorescent material uses a fluorescent material of europium activation yttrium oxysulfide coated with indium sulfide. In this fluorescent substance, visible light of short wavelength below 600nm is absorbed and reflected because the light belong to the absorption range of indium sulfide and the absorption is a little within a range between 600 and 650nm, the main luminescence wavelength range of europium. A green-light emitting component fluorescent substance uses a fluorescent substance of gold-copper activation zinc sulfide or mixed fluorescent substance of gold or copper single-activation zinc sulfide. In this fluorescent substance, effect of visible-light absorption is high within a range between 400 and 500nm. As a blue-light-emitting fluorescent substance, a fluorescent substance of silver activation zinc sulfide coated with aluminate cobalt is used. This fluorescent substance absorbs remarkably light of more than 500nm. Using those fluorescent substances makes it possible to reduce the external-light reflection without lowering white-screen brightness.

Abstract: PURPOSE:To enable the measurement of the content of alcohol in a fuel from the outside of a piping, by measuring the content of alcohol from the degree of attenuation of a microwave which is transmitted through waveguides to transmit through a fuel piping and is attenuated by this transmission. CONSTITUTION:A microwave delivered from an oscillator 5 reaches a converter 4a through a coaxial cable 6a and is emitted into a waveguide 3a from a coaxial inner conductor 61 of the cable 6a which is projected into the cavity of the converter 4a. While forming a wave electric field, this microwave is transmitted through the waveguide 3a and, traversing through a fuel piping 1 disposed midway, reaches a converter 4b through a waveguide 3b. The microwave transmitted to a coaxial cable 6b through the intermediary of the converter 4b is converted into a DC voltage proportional to the amplitude by a detector 7 and is sent as a sensor signal to an air-fuel ratio controlling device through a lead wire 7a. A sensor measures the degree of attenuation of the microwave which is attenuated in accordance with the content of alcohol in a mixture fuel and reaches the detector 7, and detects the content of alcohol accurately.
