Inventor: MIZUNO MASAO
IPC: G08G1/123
Filed: 1990-08-10
Abstract: PURPOSE:To reduce the area of a solar battery, to reduce the capacity of a battery and to realize the reduction of cost and the improvement of installation by providing a car detector and supplying the power supply voltage of a main circuit from the solar battery and a battery only when a car arrives and the detector is operated. CONSTITUTION:In a device 1 on the road, when the road is not crowded and there is no car travelling, a microphone 5 does not detect noises, the power source is not supplied to the main circuit of the transmission part or the like from the power source, and a radio wave is not sent. However, when a car M approaches, the sound of an engine and the travelling sound is caught by the microphone 5, the power source is turned on by this detection output, the radio wave is automatically sent through an antenna 4 from a main body 2, and the information such as position information is sent to the car from an on-vehicle antenna AM of the car M. Thus, the communication equipment between a car and a road equipped with a roadside equipment which requires no feeding of power and can be operated sufficiently by a small power supply can be obtained.

Title: Surface wave device
Inventor: KADOTA MICHIO
IPC: H03H9/25
Filed: 1990-08-09
Abstract: PURPOSE:To banish unnecessary spurious based on the resonance of a bulk wave from a resonance frequency/antiresonance frequency area by specifying a distance between side faces connecting both end faces where SH type surface waves are reflected. CONSTITUTION:This device is equipped with a piezoelectric substrate 1 and a pair of comb-shaped electrodes 2 and 3 at least having plural electrode tooth to be formed on the surface of the piezoelectric substrate and to be mutually interpolated so as to reflect surface waves between both end faces 1a and 1b. When the frequency of a seven times wave as large as the bulk wave standing as a standing wave between both side faces 1c and 1d is defined as (f) and the fundamental resonance frequency of the surface wave is defined as fr, a distance (l) between the side faces 1c and 1d of the piezoelectric substrate 1 is selected so as to establish the condition of f=7v/2l<fr. In this case, the (v) is the acoustic velocity of the bulk wave. Thus, the unnecessary spurious based on the resonance of the bulk wave can be banished from the resonance frequency/antiresonance frequency area of the SH type surface wave.

Title: Vehicle-borne equipment for measuring vehicle speed
Inventor: SATO KAZUO
IPC: G01S15/60
Filed: 1993-08-27
Abstract: PURPOSE:To make detection of a vehicle speed possible even when ultrasonic transducers based on a pair beam system fail to operate, by switching over detection outputs of the transducers when the detection output of the ultrasonic transducer or the rear ultrasonic transducer lowers. CONSTITUTION:An ultrasonic wave is transmitted in a prescribed beam width onto a road surface from ultrasonic transducers TRF and TRR for the front and the rear and a reflected wave therefrom is received. A signal detected by a transmission-reception switching circuit 3 is amplified 4, passed through BPF 8 and further amplified 9 and then it is binary-coded by a comparator 10. An output of the comparator 10 is sent to a PLL circuit 12 for frequency detection and a repetition frequency of pulses being proportional to the output is inputted thereby to a microcomputer 1. When a detection output of either one of the transducers TRF and TRR lowers, the detection output of the transducer TRF or TRR is switched over to the detection output of the other and computation of a vehicle speed is executed. When both of the detectors TRF and TRR fail to operate, switchover is made to the vehicle speed detection from wheels by a speed sensor.

SOLUTION: A PLL(phase locked loop) circuit which generates a clock that synchronizes with a synchronizing signal in a supplied visual signal has a phase comparator circuit 2 which compares the phases of a reference signal containing a synchronizing signal and a comparing signal and generates an output in accordance with phase difference, an oscillating circuit 4 which controls the frequency of the clock of the output in accordance with the phase difference, a frequency dividing circuit 5 which divides the clock into one to an integer and generates the comparing signal, a skew detecting circuit 11 which detects that skew deviating from a normal cycle occurs in the synchronizing signal and resets the circuit 5.  Furthermore, the circuit 11 detects that a synchronizing signal is not generated after a normal cycle passes and generates a dummy pulse, which is synchronized with a synchronizing signal and becomes a reference signal. Furthermore, when the circuit 11 detects the occurrence of skew, it resets the circuit 2.

Filed: 1990-08-09
Abstract: PURPOSE:To form a simple structure at a low cost by applying a conductive material on the side surface of one side of a machine glazed paper sheet, and by providing a residual quantity detection contact on a residual quantity detection point, and a reference contact which is slid and is in contact with the conductive material on the point of inner circumferential surface compared to the residual quantity detection contact, and a continuity detection means between both contacts. CONSTITUTION:As long as the roll diameter of a sensitized paper sheet 14 is larger than the diameter of a residual detection position A, a residual quantity detection contact 22 which is slid and is in contact at the residual quantity detection point A, and residual quantity detection contacts 24, 26 which are slid and are in contact on the inner peripheral side compared thereto, are electrically connected and are thus electrified with a reference contact 28 through a conductive material 20, and three, light emitting diodes 32, 34, 36 correspondent to three residual quantity detection contacts, are all lighted. As long as a region is smaller than the diameter of the residual quantity detection point A, and is larger than a residual detection point B, the connection between the residual quantity detection contact 22 and the conductive material 20 is cut off, and only the light emitting diode 32 is turned out. It is thus detected that the residual quantity of the sensitized paper sheet 14 is reduced by the quantity smaller than the residual quantity detection point A. In the same manner, the level of the residual quantity is detected by the stepwise turning out of the light emitting diodes 34, 36.

Title: Inspection apparatus for printed tablet
Inventor: KAJIURA TOSHIHIRO
IPC: G01B11/28
Filed: 1982-12-06
Abstract: PURPOSE:To automatically inspect the printed part of a tablet with high accuracy by an apparatus wherein a pattern feature signal is generated based on an image signal through a TV camera, and the printed area is calculated to be compared with the reference value. CONSTITUTION:A printed tablet 1 being transferred is imaged by a TV camera 2. A level comparator 6 having a given threshold discriminates the surface of the tablet 1 from the background through an image signal processing circuit 4, while a level comparator 7 outputs a binary signal to discriminate the printed part of the tablet 1 from the background. A printed area counting circuit 17 is controlled by the binary output thus produced to count horizontal and vertical area width signals through an inspection area signal generating circuit 10, so that the circuit 17 counts the printed area of the tablet 1 to generate printed area inspection information based on comparison with the reference area. On the other hand, an image signal is compared with various thresholds in a feature sampling circuit 5 to generate a feature signal in accordance with the printed or non- printed surface, which signal is compared with the reference value in a defect deciding circuit 25 to make decision. This permits the printed part of the tablet to be automatically inspected with high accuracy.
