Title: Adapter and its control method for multiple cpu system
Inventor: HATAYAMA SHIGEAKI
IPC: G06F15/177
Filed: 1988-03-08
Abstract: PURPOSE:To delete a processing program for interrupting the asynchronization of a CPU by providing a register to set a command to an adapter and executing the interruption to the CPU only when the adapter detects a bus error or an adapter error. CONSTITUTION:Plural CPU 12a, 12b and 12c are coupled with a system bus 11, and share a main memory 13. For an adapter 14, registers 21a, 21b and 21c for setting a command corresponding to respective CPUs are provided. For example, when a CPU 12a is communicated with a disk, the CPU 12a issues the request to communicate with an I/O connected to the adapter 14 for the adapter. The adapter 14 executes this, sets the error command respectively to a register 21a when an abnormality is completed and thereafter, applies the interruption to the CPU 12a. The interruption is applied to the CPU 12a only, it is not applied to other CPUs, and therefore, a processing program is made unnecessary and an execution efficiency is raised.

Abstract: PURPOSE: To display a appropriate vibration restraint effect corresponding to the vibration condition of an outer tub housing a spinning basket. CONSTITUTION: When the vibration in the upper part of an outer tub 13 is judges to be larger than that in the lower part in spinning by the values detected by an upper part sensor 57 and a lower part sensor 59 provided with the outer tub 13, the whole of a body part 25 including the outer tub 13 is moved upward relative to suspension mechanisms 15 by slide mechanisms 43 consisting of ball screws. When the vibration in the lower part of the outer tub 13 is judged to be larger than that in the upper part to the contrary, the whole of the body part 25 including the outer tub 13 is moved downward relative to the suspension mechanisms 15 by the slide mechanisms 43. Thus, the supporting position of the body part 25 by the suspension mechanisms 15 is moved to the side where less vibration occurs, reducing the vibration transmitted from the outer tub 13 to a case 11.

Title: Dielectric porcelain for high frequency
Inventor: YAMADA AKIRA
IPC: C04B35/46
Filed: 1990-03-05
Abstract: PURPOSE:To get high specific permittivity and Q value by using Sr, Ca and Ti oxides where the ratio of Sr to Ca is a specific value. CONSTITUTION:Porcelain of composition expressed by a general formula of Sr3(1-x)Ca3xTi2O7 (where 0.66<x<=0.84) is used. It is thereby possible to get a dielectric porcelain having a specific permittivity which is higher than 80 even in a microwave region and a sufficiently high Q value of 1000 or more. In case of x<=0.66 different from the above composition, Q value drops so that it becomes difficult to realize such performance as required. In case of x>0.84, both specific permittivity and Q value drop so that the characteristic required such that specific permittivity is higher than 80 and Q value is 1000 or more in 6GHz become impossible to be satisfied.

Filed: 1989-03-07
Abstract: PURPOSE:To execute a rotation processing at high speed even when a rotation angle is large by developing the rotational operation of image data of one word of an original image, in an image area having plural words. CONSTITUTION:The original image for receiving the rotation processing is inputted from an image input part 1 and stored in an image memory 6a. An operator displays the original image on a CRT 4, and inputs a rotation angle thetafrom a keyboard 5. A rotation control part 3a reads out the storage contents from the memory 6a and inputs them to a shift register, and sets/resets a bit set/reset part 3d after an arithmetic processing. In this case, the X (or Y) coordi nate of the leading bit of each line is derived by adding sintheta (or costheta) to the decimal part of a coordinate value of the line before by one and adding +1 when carry is generated. In such a manner, a coordinate after the rotation of a head picture element of each line is obtained. By repeating such an opera tion with regard to each picture element, a rotary image is obtained.
