Title: White balance correcting circuit
Inventor: NAKAMURA TAKASHI
IPC: H04N9/73
Filed: 1987-10-01
Abstract: PURPOSE:To effectively correct a white balance by discriminating a level by defining the mean value of the reference voltage of two successive fields to be a threshold and generating a gate pulse. CONSTITUTION:The reference voltage generated from a reference voltage generating circuit 5 based on the signal of the 2n-th field F2n of an arbitrary even numbered field and the reference voltage based on the signal of a (2n+1)th field F2n+1 succeeding to the field F2n are added and averaged by an adding and averaging circuit 7. In a comparator 4, the signal of a further succeeding (2n+2)th field F2n+2 and the signal of a (2n+3)th field F2n+3 are discriminated in level by defining the synthesized reference voltage of a n-th frame obtained by the addition average to be the threshold to generate the gate pulse. According to the obtained gate pulse, a white part is effectively taken out to improve the accuracy of the white balance correction.

Title: In-circuit tester
Inventor: NAGANO KATSUMI
IPC: G01R31/02
Filed: 1987-09-30
Abstract: PURPOSE:To make it possible to measure the mounted state of an integrated circuit without fail, by connecting first and second contacting means to a first terminal to which a power line of the integrated circuit is connected, or to a second terminal to which the power line is not connected. CONSTITUTION:When relay switches RL1 and RL2 are put in the ON state by the control of a control element CT, a power VS is supplied to an integrated circuit IC through a bus line BS1, the switch RL1, a probe pin CP1, a test land TL1 and a lead pin LP1. Since the switch RL2 is in the ON state, an output voltage V0 of an operational amplifier MOA for measurement turns to be as expressed by an equation V0=-Rref.VS/R. Since a conversion resistance Rref and the voltage VS are already known, a resistance value between test lands TL1 and TL2 can be determined by measuring the voltage V0 of the amplifier MOA by the control element CT, and it can be discriminated therefrom whether the mounted state of the integrated circuit IC1 is normal or not.

Abstract: PURPOSE:To reduce the overall weight of a lift and soften a shock applied to a load-carrying deck at the time of preventing dropping by holding a wire rope which is tense along a guide column by means of a cam and a supporting piece to prevent the lead-carrying deck from dropping. CONSTITUTION:When a lift chain 3 is cut, a shaft 15 is traveled downward by a compression spring 19, and a lever 16 is inclined in a downward position indicated by a two-dot chain line, making a stopper 22 serve as a fulcrum. Therefore, a protruding piece 23 separates from the contact part 27 of a cam 24, cam 24 rotates counterclockwise by the tension of a spring 29 to hold a wire rope 4 by means of the rope pressing part 28 of cam 24 and the supporting recessed part 32 of the supporting piece 31 to prevent the load-carrying deck 2 from dropping. Slight drop by the dead weight of the load-carrying deck 2 rotated the cam 24 counterlockwise further, and the rope pressing part 28 of the cam 24 is caught in the wire rope 24 to prevent the load-carrying deck from dropping completely. When the cam 24 rotates, a sensor 30 senses that a dropping prevention device operates, and the power source of a lifter is stopped to prevent the secondary accident.

Title: Emergency removing for fluid cargo handling device or the like
Inventor: TAKAHASHI CHUYA
IPC: F16L37/20
Filed: 1992-09-16
Abstract: PURPOSE:To increase the reliability of operation. CONSTITUTION:When a cylinder 10 is extended and a fixing member 13 is pushed by a pressing device 29, a connecting rod 8 and a lever 33 are rotated around a pivot shaft 18 and a mounting shaft 35, respectively. A lock roller 22 comes out of a connection lock part 9a by the rotation of the rod 8, is locked on a loosened lock part 9b, and moves along the lock part 9b. The lever 33 pushes a protrusion 1b when the lock roller 22 moves along the loosened lock part 9b to rotate clasps 4, 5, and 6 in circumferential direction of a transport pipe 1. A retaining pin 36 is disengaged from a hook fitting 1c by this rotation. Because a lever 33 touches a stopper 37 when the pin 36 is disengaged, the rotation of the connecting rod 8 around the pivot shaft 18 is stopped, and the clamper 4 is rotated integrally with the rod 8 around a connecting pin 7 between the clampers 4 and 5 to separate from the transport pipe 1. Thus a proper looseness can be maintained while the roller 22 is engaged with the loosened engaging lock part 9b, and all the clamps are rotated securely.

Filed: 1987-09-30
Abstract: PURPOSE:To quickly transmit information between terminal equipments by generating a packet of frame structure having minimum additional information in response to the characteristic or classification of transmission information of a terminal equipment and sending the result so as to minimize the connection delay. CONSTITUTION:For example, identification information representing the classification of an R terminal equipment 20 and its own node address is given to an instantaneous information low speed line interface section (LR section) 100 as a fixed data and the LR section 100 generates a packet for instantaneous information of prescribed frame structure based on the fixed data. That is, the packet exchange 10 omits the information used for the relation of adjacent node such as an adjacent node address and applies no error check as to the instantaneous information and applies error check in the lump for the final frame as to continuous information by the production of the packet of frame structure. Thus, the information added to the transmission data is the required and minimum data to reduce the connection delay into a minimum time.

Abstract: PROBLEM TO BE SOLVED: To obtain a power door system, in which a power door is not opened when a passerby merely process the vicinity of an entrance of the power door. SOLUTION: A data processing device prepares S12 a differential image acquired by subtracting an initial image from a detected image on the basis of a digital data S11 input from a subtracter. The data processing device decides S13 whether or not the shadow of a gray scale appears in the prepared differential image, and computes S15 a maximum value Xm in width in the X direction regarding the shadow of the gray scale when the shadow of the gray scale appears in the differential image. The data processing device compares S15 the computed maximum value Xm with a preset threshold value Xth. Accordingly, when the computed maximum value Xm reaches the threshold value Xth or more, the data processing device judges the facing to a front to a power door 1 in a passerby, and outputs S16 a driving control signal C for opening the power door 1.
