Title: Power transmission mechanism
Inventor: TAWA TETSUO
IPC: B65H5/02
Filed: 1989-09-28
Abstract: PURPOSE:To keep the engagement of a first gear with a second gear in a normal condition by connecting a first shaft to a second shaft by connecting member through bearings so as to extremely reduce the bite of the first shaft by drive of a belt. CONSTITUTION:When rotation of a first shaft 11 is transmitted by drive of a belt 18 to a second shaft 19, even if a bending stress is applied to the first shaft 11 by the belt 18, the first shaft 11 is connected to the second shaft 19 by a connecting member 32 through bearings 33. A force against the stress is therefore strong to prohibit biting, where the distance between the shafts of a first gear 16 and a second gear 26 is not changed, so the engagement of the first gear 16 with the second gear 26 is kept in a normal condition to rotate smoothly, thereby abrasion will not occur, and the life is secured.

Title: Data conversion effectiveness deciding circuit
Inventor: KONDO TOSHIHIKO
IPC: H03M1/12
Filed: 1988-10-07
Abstract: PURPOSE:To output a data effective signal and to attain read of a correct data to a CPU by deciding whether a data is effective or ineffective depending on the detection of two retarded busy signals outputted from a flip-flop. CONSTITUTION:An input signal 1 before conversion is converted by a data converter 2 and goes to a converted digital data 3 and a busy signal 5 is outputted during data conversion. It is after a prescribed time after a busy signal 5 is ineffective that the conversion digital data 3 is stable and ensured. Thus, when a timing flip-flop 6 detects the busy signal 5, a 1st delay busy signal 19 is outputted in the timing of a reference timing 15 and a trigger signal 7 being a 2nd delay busy signal is outputted based thereupon, then the converted digital data 3 is fetched in a conversion data register 4 at a point of time of prescribed time delay after the detection of the busy signal 5.

Title: Traveling distance measurement error correction method for gyro-guidance type automated guided vehicle
Inventor: MAKINO FUMINORI
IPC: G01C19/28
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the a failure that an accurate truck position can not be computed when error is caused in measurement and to correct such an error of a measurement system in a gyro-guidance type automated guided vehicle. SOLUTION: In this method, during automatic traveling by a gyro, the truck position is computed by a computing element by using the measured value of the steering angle of steering or the like. In this case, when a magnetic sensor 2a installed to a truck body 5 is passed on a magnetic marker 4a installed on the guide line of a floor surface and a shifted amount in a position is detected, a traveling distance integrated in the computing element is reset.  When the magnetic sensor 2a is passed on the next magnetic marker 4b and the shifted amount is detected, since the traveling distance 1 is recognized from the measured value of a traveling distance sensor at the time and the distance Lp of the magnetic marker 4a and the next magnetic marker 4b are recognized from traveling path information set beforehand, a correction coefficient C is calculated corresponding to the equation of C=Lp/1. Thereafter, the one for which the correction coefficient C is multiplied with the traveling distance is used as the traveling distance of truck position computation.

Title: Lens barrel drive controller for camera
Inventor: ISHIGURO MINORU
IPC: G02B7/08
Filed: 1994-10-20
Abstract: PURPOSE: To provide a lens barrel drive controller for camera capable of moving a lens barrel to an accurate position. CONSTITUTION: The state signal generated by a state signal generating means 30 is a signal by which a state is changed based on the positional relation of the lens barrel 10 to one reference position, and moving means 20 and 40 control the movement of the lens barrel 10 only by the state signal. Therefore, the position of the lens barrel 10 is detected only at the reference position, and in each movement processing of the moving means 20 and 40, the position is detected by moving the lens barrel 10 up to the reference position temporarily, and then, the movement to a standby position, a focusing position, etc., is controlled with the reference position as a reference. Since the movement is controlled based on the detection of the position of the lens barrel 10 at one reference position, the risk of causing an erroneous detection is reduced and durability is remarkably improved.

Abstract: PURPOSE: To make it possible to pursue and detect a defect of a circuit component by minimum inspection by pursuing the faulty component and using another node for inspection measurement if a shock is applied to a circuit and the defect is detected. CONSTITUTION: For example, a circuit consisting of transistors(TR) Q1 to Q3 power supply lines Vcc and Vee , resistor R1 to R8 , an input IN, and an output OUT is given a series of shocks including an electric signal and response voltages are measured at circuit nodes 1 to 10 in order to detect a defect of a circuit module (component). Assuming that the TR Q3 and resistors R5 and R8 are suspected of defectives when electric power is measured at the node 9 for defect detection, it is verified that the TR Q3 has only one defect when a measured value is 15 V by removing the resistor R5 and R8 having a slight overlap (9.48 to 9.16V) of measured values when the respective measured values are 15 to 14.90, 9.48 to 15, 10.18 to 9.16V.  When the faulty component is verified, another node is further selected and inspection measurement is carried out to decrease the number of suspicious components.
