Title: Local maintenance terminal
Inventor: WAKIYAMA SATOSHI
IPC: H04W88/18
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To facilitate a maintenance operation, to protect security, and to record who carries out a maintenance operation at a base station by connecting between a personal computer and a base station through an infrared communication line and confirming whether or not a normal maintenance terminal is used to perform the maintenance of the base station. SOLUTION: In authentication processing, processing is activated by sending a communication start requesting signal from a personal computer side which is a local maintenance terminal 5 to a base station BS2. When the station BS2 receives the communication start requesting signal, it sends communication start response and a starting code requesting signal to the personal computer side. The personal computer side receives them and sends a starting code response signal to the station BS2, and the station BS2 carries out authentication processing by the response signal.

Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a transmitting device and method which prevent the omission of video information even when entire video data from a server is not received due to the transmission band of a line and the throughput of a client. SOLUTION: An encoding part 1 performs intra/inter-frame coding of an input video according to an instruction and notice from an I(intra) frame inserting and deciding part 7, gives an ID(identification) to an inter-frame which is undergone intra-frame coding as a video sequence group and successively stores an encoded video in transmitting buffer memory 2. On the other hand, a frame superimposition video generating part 3 generates and encodes one pieces of a still picture that represents the movement of videos in the group like afterimage effect by overlapping plural frames, gives it the same ID and stores it in a storing medium 8.  When the encoded video of an ID which is signaled by a client's video transmission request is already updated and does not exist in the memory 2, a transmitting part 9 reads and transmits an encoded still picture that corresponds to the ID, interpolates an original video to be transmitted and prevents the absence of video information.

Then a square lattice is stuck onto the shape model, and the lattice points near the inside or the outside of the boundary line of the shape model are selected and connected to each other as a boundary line of a similar shape model. Furthermore the similer shape model is mapped onto the shape model so that both boundary lines are coincident with each other. Thus the finite elements are generated in division.

Title: Drive circuit for fluid pressure actuator
Inventor: NAITO HISATO
IPC: E02F9/22
Filed: 1992-10-05
Abstract: PURPOSE:To restrict the speed of other actuators from slowing down as well as to restrain increase of load pressure generated at the time of starting an actuator which is connected to a heavy load, by providing a plunger to press down a pressure compensation spring in response to the pressure from a sequence valve and a restrictor equipped downstream from the sequence valve. CONSTITUTION:When an excessive load is applied to an actuator provided with a sequence valve 13, among a plural number of actuators driven by virtue of the pressure from a variable capacity pump 9, the load pressure to the actuator raises to a specified pressure and a sequence valve 13 opens. In order for a plunger 12 to press down pressure compensation springs 5, 6, which are housed in pressure compensation valves 3, 4, by virtue of the load pressure supplied from the sequence valve 13, the established pressure for the pressure compensation valves 3, 4 rises, whereby reduces the pressure differential between nose in front and rear or directional control valves 7, 8 and regulates the pressure added to the actuator. Thus operating speed of other actuators can be prevented from slowing down as well as excessive increase of load pressure on the actuator, on which excessive load is added, can be restrained.
