Title: Bus right deciding system
Inventor: MURAKAMI MASAHARU
IPC: G06F13/362
Filed: 1987-09-18
Abstract: PURPOSE:To improve the operability and maintenance of a system by detecting the position of a connector to connect a CPU and setting automatically the priority of a bus right even when to which connector and adapter connected to the bus is connected. CONSTITUTION:At the time of the initial setting, a CPU 1 detects successively to which connector position on a CPU bus 3 respective adapters 5 and 7 are connected. By the action, the CPU 1 determines the CPU bus right priority of respective adapters 5 and 7 and stores it into a storing part. The output of the storing part is sent to a logical part (arbiter)2 having a function to give the bus right from the adapter having a higher priority and the conditions of the priority decision are formed. Thus, the arbiter 2 can be realized in which the priority is made variable and the using efficiency of the bus can be always made optimum. Since the CPU 1 can discriminate a connector number and adapter information, any adapter my be connected to respective connectors and the erroneous connection of the adapter is not executed.

Title: Non-contact ic card system
Inventor: WATANABE TAKAHIRO
IPC: G06K19/07
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To attain efficient demodulation by using phase change by providing a phase shifter between a carrier wave oscillator and a multiplier, and changing the phase of the carrier wave for operating multiplication. SOLUTION: A phase shifter 6 is inserted between a carrier wave oscillator 5 and a multiplier 7 of a reader/writer unit(RWU) of a non-contact IC card system. In a load switch system for changing a capacitor to be inserted in parallel into the coil antenna of the non-contact IC card, when the capacity of the capacitor is changed, parallel oscillation frequency with the coil antenna is deviated from the frequency of a carrier wave received for a power, and the amplitude and phase of a carrier wave transmitted from a coil antenna 1 of the RWU is changed. In this case, the amplitude difference is changed by changing the phase shift amounts of the phase shifter 6. That is, the phase shift amounts for obtaining the maximum amplitude difference value is set by the phase shifter 6 so that an efficient data demodulator can be obtained.

The air in the impeller 23 is discharged under increasing the pressure thereof between a multitude of blades 31. The discharged air flows into a multitude of volute chambers provided at the outer periphery of the impeller 23, guided by a fan casing 37 curved smoothly and the dynamic pressure of the air is converted into the static pressure of the same efficiently during this period. According to this method, the efficiency of the fan may be improved and the smooth intake of the air may be effected.

Title: Ball joint
Inventor: EIICHI ITOU
IPC: F16C11/06
Filed: 1984-11-07
Abstract: The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.

Title: Frame synchronizing device
Inventor: NAKAMURA TAKAHARU
IPC: H04J3/06
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To avoid erroneous synchronous detection by means of a pseudo frame synchronizing other than a frame synchronizing signal included in a reception signal. SOLUTION: A means 31 detects the frame synchronizing signal in the reception signal with the error allowance of a prescribed bit. A control means 33 controls an aperture for outputting an aperture signal (A) which causes a detection signal to pass through by a gate 32 at every time L corresponding to a frame synchronizing period from the supply time of the detection signal. A protection means 34 judges it as a frame synchronous state when it continuously detects passage detection signals for the prescribed number of times. Furthermore, a means for storing the number of erroneous bits less than error allowance which the detection means 31 outputs and a comparison means 36 outputting the aperture set signals(AS) to the means 33 when the number of the erroneous bits is less than the number of stored erroneous bits are provided.  The means 33 rests previous aperture control at the time of AS input and outputs A at every time L from input time.
