Title: Peak detector and bottom detector
Inventor: MORIE TAKASHI
IPC: G11C27/00
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To allow the maximum and the minimum of an input signal to be rapidly detected with small-sized circuitry without using an operational amplifier or a diode by constituting a differential input part and a current mirror of transistors(Tr). SOLUTION: Three Tr's Q1, Q2, Q3 constitute a differential input part 6, Tr's Q4, Q5 constitute a first current mirror 7, and Tr's Q6, Q7 constitute a second current mirror 8. A capacitive element C is connected between a drain of a Tr7 and a power source terminal 2 in a peak detector. When voltage Vin > voltage Vout, the capacitive element C is charged and approaches voltage Vin. When voltage Vin<voltage Vout, current flowing into the capacitive element C is also zero. Thus output voltage Vout does not change, holding a previous voltage value. In such a manner, the peak detector detects the maximum of voltage Vin and outputs as output voltage Vout. In a bottom detector, the capacitive element C is connected between a TrQ and a power source terminal 1.

Title: Multi-path delay time measurement device
Inventor: SHIBUYA TOSHIFUMI
IPC: G04F10/06
Filed: 1980-07-21
Abstract: PURPOSE:To accurately measure the delay time independently of the content of FM modulation, by approaching an interference pattern to one line, through the adjustment of the delay time of a variable delay device. CONSTITUTION:The output of an intermediate frequency filter 3 is the synthesized wave between a desired wave and a reflected wave, and the delay time for the synthesized wave is expressed as tau/2, where the delay time of the reflection wave is tau. The level of this synthesized wave is made constant with an automatic gain control circuit 6, AM modulation is made at an AM detector 7 and inputted to a terminal 8 of a plane drawing display device 10. On the other hand, the output of the filter 3 is added to an FM detector 5 via a limiter circuit 4, and the demodulated output is adjusted for the delay time to tau/2 with a variable delay device 11 under delay time control 12 and inputted to a terminal 9 of the device 10. Since the interference pattern of the device between the FM detected output with equal delay time and the AM detected output is one locus, the positions of peak and bottom are measured accurately.

Title: Method for automatically reading vehicle number
Inventor: KATO KENJI
IPC: G06K9/20
Filed: 1985-05-10
Abstract: PURPOSE:To apply a picture processing to a vehicle number plate and to discriminate a vehicle number character by optically detecting the existence of a mark disposed on the surface of a road on which the vehicle passes in a visual field and stopping the fetch of the mark when there is no mark to change over to a vehicle number reading. CONSTITUTION:A simple graphic is clearly disposed as the mark on the road surface in the visual field of a television camera 10. While the mark is recognized, it is judged to be no vehicle. When the mark is not recognized a vehicle sensing algorithm is changed over to a vehicle number reading algorithm and the vehicle number is read by a picture processing circuit 14 and a character discriminating circuit 15. In this manner, the judgement of the existence to be detected is easy and a processing may be carried out only on a position having the mark and the processing of an picture is not required, so that a judgement algorithm can be simplified.

Title: Automatic focus controller
Inventor: KAWABATA TAKASHI
IPC: G03B13/36
Filed: 1984-05-17
Abstract: PURPOSE:To shorten the time for focusing by early predictable drive based upon the movement, etc., of a subject by comparing the subject position estimated from the integral value of the quantity of reflected light of luminous flux projected on the subject with the current lens position of a photographic lens and driving the lens roughtly. CONSTITUTION:The reflected light from the subject is photodetected by photodetecting elements 8 and 9, whose output difference is amplified by a differential amplifier 14 to perform automatic focus control through a photographic lens driving electric motor 1. If the subject position and lens position are extremely different from each other, the lens is not put in accurate focusing operation through the differential amplifier 14, but driven roughly with the output of a summing amplifier 20. When the lens is close to the focusing position, the output of a lens position detecting circuit 2 is small, the output of the differential amplifier 41 becomes high, and an OR gate 49 is inverted to a level H, so that the Q output of a monostable multivibrator 51 is held at the level H for a specific time. A D latch circuit 52 is latched with this Q output and the H-level output of a comparator 43 is applied through the output Q2 of the latch circuit 52 to control the electric motor 1 through an adder 17.

Title: Data comparator
Inventor: YOSHIZAWA MASAYUKI
IPC: H03K23/66
Filed: 1984-05-17
Abstract: PURPOSE:To decide the relation of quantity between a frequency division data at an outut of an RS flip-flop and a comparison data by setting an RS flip-flop with an output being a product of full bit output and resetting it at zero state of a frequency division means. CONSTITUTION:The circuit is simplified by using an OR circuit for a circuit part having been using an exclusive OR circuit. When an output state of a frequency division circuit is larger than a data, a signal of an AND output goes to either High or Low when the OR circuit is used. A stage of 1/2 frequency division circuit is provided next to the final stage of the former frequency division circuit, the edge detection is attained, the result is inputted to a reset terminal of a flip-flop circuit with set/reset and an output ANDing the OR output is inputted to the set terminal. Thus, when the output state of the frequency division circuit is smaller than the comparison data value, a node 2 has a low output and when equal to or larger than, a high level is outputted to the node 2.
