Title: Electronic meter for automobile
Inventor: MIZUNO TOORU
IPC: G01D3/02
Filed: 1980-11-20
Abstract: PURPOSE: To harmonize light-depreciation of different kinds of display elements, by light-depreciating one display part by a pulse signal having a constant frequency and a prescribed duty ratio, and also light-depreciating other display part by a signal whose duty ratio is different from that of said pulse signal.  
     CONSTITUTION: When a light 2 is lighted by a lighting switch 1 at night, an oscillating circuit 10 which is capable of changing a duty ratio by a constant frequency is operated. When an output of this oscillating circut 10 is in an L level, a meter lighting lamp 20 is lighted. Also, the output of the oscillating circuit 10 is converted to a pulse signal whose H level time is long, by a converting circuit 30. FLT is lighted by an L level of this converted pulse signal, and a luminance variation of the FLT is made similar to a luminance variation characteristic of the lamp 20. In this regard, said constitution is applicable to LED, too, in the same way.

Title: Terminal equipment for automatic metering system
Inventor: SAKAIDA SHINYA
IPC: H04Q9/14
Filed: 1987-07-01
Abstract: PURPOSE:To send a consumption quantity signal accurately within a preset time zone by correcting the time of a clock means based on the accurate time preserved in a management center. CONSTITUTION:A crystal oscillation circuit 9 and a microcomputer 7 constitute a clock means controlling the transmission time of the consumption quantity signal. Moreover, when the circuit 9 and the computer 7 send a signal with the management center, they also act like a time correction means correcting the time to be stroed based on the accurate time preserved by the management center. Through the constitution above, the time preserved in the clock means, even with more or less error, is corrected based on the accurate time preserved in the management center every time the signal is sent to the management center. Thus, no large deviation due to accumulated error is caused and the transmission of the consumption quantity signal is implemented accurately within the preset time zone.

Abstract: PURPOSE:To eliminate the need for pushing in of an eyepiece by an observer by using a liquid crystal in the imaging position of the output electronic image of a dark viewer, and using a light projector for the liquid crystal and a detector for detecting the presence or absence of the observer. CONSTITUTION:The light from a target object 1 illuminated by a weak light is imaged through an objective lens 2 on the fiber plate face 8 of an image intensifier 3.

Abstract: PROBLEM TO BE SOLVED: To eliminate the existence of a spurious so as to obtain a surface acoustic wave resonator where equivalent resistance is small and oscillation is easy without a frequency jump by weighting intersection width by means of a function 2, which is almost in proportion to the displacement function of a high-order longitudinal enharmonic mode in the specified surface acoustic wave resonator. SOLUTION: When the electrode fingers 107 (positive electrode) and 108 (negative electrode) of interdigital electrodes(IDT) 103 and 104 are made to be a pair and the M pairs are provided, an energy confinement surface acoustic wave resonator where a total reflection coefficient Γ in the electrodes as a whole in IDTs 103 and 104 is made to be 10>Γ>0.8 is constituted. The intersection width of the electrode fingers 107 and 108 of the IDTs 103 and 104 in the surface acoustic wave resonator is weighted by width, in relation to a main resonance displacement function, being the basic wave mode of a high-order longitudinal made group. Thus, the longitudinal in-harmonic mode is suppressed, the surface acoustic wave resonator without the spuriousness is realized, and a frequency without the frequency jump is normally obtained in a frequency variable-type oscillator.
