Title: Bus controller
Inventor: ANPO FUMIHIRO
IPC: G06F13/28
Filed: 1989-04-19
Abstract: PURPOSE:To validate an output with a delay approximately equal to the delay time of a gate and to attain the working of a bus controller at a high speed by validating a bus request signal via a 1st controller. CONSTITUTION:When a main controller 10 outputs a request signal 14, the output of a control circuit 25 is invalidated and an access grant signal 36 outputted from a bus arbiter 20 is also invalidated. This state lasts until the controller 10 finishes the use of a bus. When the controller 10 is through with use of the bus, the output of the circuit 25 is validated and the signal 36 is also validated. However the signal 36 is never validated to a 1st controller 30 unless the other input of an AND circuit 26, i.e., a bus request signal 34 is valid. Under such conditions, the output of the circuit 26 is validated with a delay approximately equal to the delay time of a gate if the controller 30 validates the signal 34. Thus the signal 36 is immediately inputted to the controller 30.

Filed: 1987-04-20
Abstract: PURPOSE:To cover offset of combination error between a fixing error and a gap error by providing reverse input phase to an auxiliary unit angle signal to be detected through an electromagnetic pickup when an included angle of engine is integer times of unit angle. CONSTITUTION:Projections 1a are provided with predetermined angular interval on the circumference of a rotary body 1 interlocked with the crank shaft of an engine, where one of the projections 1a is missed. Referential position is detected by employing a signal detected through an electromagnetic pickup 2B as an auxiliary unit angle signal.

Filed: 1992-04-17
Abstract: PURPOSE:To prevent the generation of speed change shock by setting an operation oil pressure supplying to a low speed side friction engagement means to a prescribed value in the switch of a speed change indication to a downshift. CONSTITUTION:An automatic transmission 2 is composed of a torque converter 4, a gear transmission 3, a hydraulic circuit 5 and a controller 40 and the like. When it is switched to the speed change indication of downshift during upshift enforcement, at first the operation oil pressure in a low speed side friction engagement means is set to a prescribed value and a play filling operation is carried out. When it is finished and the low speed side friction engagement means starts to engage actually, the revolution speed of an input shaft and the change rate of this revolution speed are increased. Therefore, when this change rate reaches a prescribed value, it is judged that the play filling operation is finished and the feedback control of the operation oil pressure in the low speed side friction engagement means starts. Accordingly, the low speed side friction engagement means can be engaged by a proper operation oil pressure and the speed change shock can be reduced.

Title: Traffic observing device
Inventor: SHIOMOTO KOHEI
IPC: H04L12/28
Filed: 1995-04-24
Abstract: PURPOSE: To calculate a proper fair share by providing respective means for setting the time of the incoming of a cell in the time describing area of a pertinent address, detecting connection to be a processing object on a connection table and judging whether the connection is active or not. CONSTITUTION: This device uses a connection (Cn) table provided with the three fields of a flag, a window size(WS) and a time stamp(TS) showing whether the connection is active or not at each data connection (Cn). A scheduler 13 executes cell incoming processing and selects the preparation of the update processing order of the table 12 and Cn to be the processing object. On the other hand, an active judgement part 14 judges whether Cn is active or not from WS and TS of Cn specified by the scheduler 13 and from the value of a timer 11. In addition, a cell incoming time monitoring part 15 sets the present time of the timer 11 to the field of TS of the pertinent address of the table 12 corresponding to Cn identified by the scheduler 13 at the time of cell incoming processing time.  Thereby, the proper fair share is calculated even when a cell sending rate is separated from an actual value.
