Title: Automatic adjusting mechanism for stereoscopic camera convergence angle
Inventor: SUZUKI TAKAO
IPC: H04N13/02
Filed: 1987-10-05
Abstract: PURPOSE:To attain the automatic adjustment of a convergence angle by executing a motor driving so that specified areas in right and left videos can be coincident. CONSTITUTION:Videos to be incoming respectively from left and right lens 3a and 4a are photo-electrically converted by image pickup elements 3b and 4b. However, attention is paid to a luminance (y) signal in these electric signals and a convergence angle revolving motor 6 is controlled so that the images of the specified areas of the respective right and left images can be compared and coincided. Namely, the right and left luminance signal to be outputted from the image pickup elements 3b and 4b are inputted to gate circuits 13 and 14 and these gate circuits 13 and 14 are controlled so as to be opened only for the specified area in the image by a horizontal dot counter 9 and a line counter 10. A comparator 11 compares the luminance signals of the specified areas of respective right and left cameras and a motor 6 executes a search through a motor driving circuit 7 until the images of the specified areas of the two cameras are coincident. Thus, the convergence angle adjustment of the two cameras can be automatically executed.

Title: Leg housing mechanism for child seat device
Inventor: KANEKO TOMIHISA
IPC: B62B7/08
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce a space necessary for housing by hingeconnecting left and right leg parts by crossing two legs in an X shape, adjusting the heights of the leg parts by changing a crossing angle and preventing the same from being smaller than a minimum crossing angle necessary for strength. SOLUTION: A rear leg material 113 is hinge-connected to a leg main body 111 and the other leg material 113 is hinge-connected to the hinge connecting part 121 of a slide bar energiged by a spring in the direction for extending and making higher a leg part 3. A stopper 141 is provided in the bottom surface part of the leg main body 111 so as to be brought into contact with the leg material 113 and, since the advantage of strength is lost if the X-like crossing angle of the leg part 3 becomes too small, the stopper 141 is brought into contact with the upper side of one leg material 113 to prevent further folding of the same, and a desired minimum necessary crossing angle is secured. For housing, the stopper 141 is rotary-moved, the leg material 3 is moved away and folded deeply and thereby the height of the leg part is reduced. Thus, a housing space is reduced.

Patent JP-S60201464-A (JP)
Title: Microcomputer system
Inventor: MAAKU EDOWAADO DEIIN
IPC: G06F13/28
Filed: 1984-11-30
Abstract: A microcomputer system includes a main processor (1), a memory (3) and a direct memory access controller (DMA;4) effective to control direct data transfer between the memory and input<sub>/</sub>output devices on channels. Bus control for data transfer is switchable between the DMA and processor by a hold request/acknowledge handshaking sequence between the DMA and processor. A control line (27) from the channels is activated by a peripheral processing device on a channel when it wishes to gain control of the busses for data transfer. Logic means co-act with the handshaking sequence to determine which device gains control of the busses. This logic is responsive to the DMA address enable output (AEN), the hold acknowledge output of the main processor (HLDA) and the channel control line output (-MASTER). When all these are deactivated, control passes to the main processor, when AEN and HLDA only are activated, control passes to the DMA controller and, when all three are activated, control passes to the peripheral processing device.

Title: Network switch
Inventor: NITANI MICHIO
IPC: H04L12/66
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent network switch processing time from being extended at the time of continuous reception from plural ports by providing a circuit for processing the registration/deletion of a transmission source address separately from a CPU for transfer processing. SOLUTION: A CAM 23 stores the addresses of stations connected for each port. When a frame is received, a CAM inside data managing circuit 60 extracts the transmission source address from received data and performs access through an arbitration circuit 61 to the CAM 23. The CAM 23 retrieves the transmission source address and sets an access bit to data in its preservation part and frame transfer to the transfer destination port of the destination address is processed through a CPU 24. At such a time, when the transmission source address is not registered yet, it is registered as preservation part data. The CAM inside data managing circuit 60 periodically accesses the CAM 23 and deletes address data for which no access bit is set to the preservation part data.
