Title: Schmitt trigger circuit
Inventor: TATAI TOSHIO
IPC: H03K3/353
Filed: 1983-01-14
Abstract: PURPOSE:To obtain a threshold level with high accuracy by means of a small integrated circuit by constituting a Schmitt trigger circuit obtained by adding one stage of an output inverter to the Schmitt trigger circuit formed with an operational amplifier only. CONSTITUTION:An output of the operational amplifier 1 is received by the inverter 2 and an output of the inverter 2 is supplied to an input of the amplifier 1 via a feedback circuit RF. Since the gate potential of the inverter 2 is a potential close to a power supply voltage for both a P channel transistor (TR) and an N channel TR, the size of the TR of the inverter 2 is made smaller in comparison with the circuit system extracting a current from the output of a conventional operational amplifier. Further, output TRs Q8, Q9 of the amplifier 1 can be made small in size because of inverter drive only and the current is small. Moreover, a gate potential of the output inverter is larger, the potential drop by TRs Q10, Q11 is suppressed to a small value and the threshold level is decided by the resistance ratio of R1, R2 and Rf.

Patent JP-S56102185-A (JP)
Title: Remote control device
Inventor: MORII SHIGERU
IPC: G10L15/00
Filed: 1980-01-17
Abstract: PURPOSE:To make it possible to control a machine to be controlled remotely with voices even  from the remote place beyond the range that voice can reach by converting a voice signal into a  ratio wave and receiving the transmitted radio wave with the antenna which uses a part of the  configuration parts of the machine to be controlled. CONSTITUTION:Remote control device B is composed of hand transmitter 9 consisting of microphone 10, radio wave oscillator 12 and antenna 11. When a specific registerd person generates  control voice to microphone 10, radio wave is sent from the antenna. Since protection net 8 of  electric fan A, a machine to be controlled, is used as an antenna, net 8 receives the radio wave  and applies it to voice radio wave receiver 14 mounted on base board 1. Receiver 14 applies the received radio wave to radio wave current converter 15, which converts the received radio wave  into the amplitude and frequency corresponding to the voice radio wave and applies them to voice recognition device 16. Since device 16 stores the voiceprints of specific users and specific instruction words, device 16 compares the inputted voice current with stored voiceprints and generates  an instruction signal only when the two coincide with each other. Thus, remote control is possible  even from the remote place outside the range that voice can reach and error control caused by  noise or the like can be also prevented.

This is confirmed visually and a necessary image frame 9 in the batch 10 is found by manual operation. Thus, respective batches continue according to the constant rule and marks 12 are provided corresponding to the indexes 11 to facilitate the retrieval and reduce the trouble.
Patent JP-H02184979-A (JP)
Title: Pattern inspection device
Inventor: TAGA HINAKO
IPC: G06T1/00
Filed: 1989-01-11
Abstract: PURPOSE:To eliminate the strictness of positioning accuracy and to minimize memory capacity by comparing the curvature of the contour point sequence of an article to be inspected with the curvature of the contour point sequence of a nondefective having the same label as that of the article to be inspected at every point sequence and deciding that a defect exists in the label graphic of the article when the absolute value of the difference between the two curvatures is larger than a reference value in a certain comparison. CONSTITUTION:The calculation of the absolute value of the difference between the two curvatures in a chip and protrusion detecting circuit 7 is executed by taking out the curvature of each picture element in the sequence of the point sequence of each input graphic for an input circuit for the same label of the nondefective and the article. When a defect detecting signal (j) is generated, it is decided either the defect of a pinhole or the defect of a black point exists. Further, when a defect signal (n) is generated, it is decided either the defect of a chip or the defect of a protrusion is included. Consequently, the curvature data of the contour point sequence of the input graphic is enough for information necessary for a storage circuit 6. Thus, the capacity of the storage circuit 6 can be minimized, and strict positioning becomes unnecessary by using labeling information about the contour of a binarization picture and the curvature of the contour point sequence for the detection of the defect.

Title: Planetary gear type differential device
Inventor: TERAOKA MASAO
IPC: F16H48/38
Filed: 1992-01-16
Abstract: PURPOSE:To prevent power loss and the lowering of fuel consumption by providing a rotating section between the first or the second planetary gear and a carrier with a differential restricting means, and moreover providing that means with a friction clutch and a pressurized spring to give proper fastening force to the clutch. CONSTITUTION:Driving force inputted into a differential case 3 drives the first and the second planetary gears 13, 15 from an internal gear 9, the right wheel from the right carrier 23 through the right hub 7, and the left wheel from a sun gear 11 through the left hub 5. When a difference in driving resistance occurs between the right and left wheels, the autorotation and revolution of the planetary gears 13, 15 differentially distribute the driving force to the right and left wheels. In this case, the rotation of the planetary gears 13, 15 is braked by the frictional torque of a rotating section, and as transmitted torque is larger, the frictional torque becomes larger to strengthen differential restricting force. On the other hand, a disc spring 33 between the right carrier 23 and the differential case 3 always presses a cone clutch 31 to give it proper initial torque for producing proper differential restricting force irrespective of the size of the transmitted torque and the number of revolutions. Thus power loss can be reduced, and fuel consumption can be improved.
