摘要： PURPOSE:To prevent the bonding destruction of a tip end portion of a lead pin by soldering one end of a lead pin with an electrode arranged on the rear of the insulating substrate of a microchip carrier, soldering or brazing the other end with an electrode on the main surface of a printed wiring board, and making the deformation strength of the lead pin smaller than the bonding strength of both ends. CONSTITUTION:One ends of lead pins 11 are subjected to soldering or brazing with electrodes 8 arranged at specified intervals on the rear of the insulating substrate 4 of a microchip carrier 2, The other ends are subjected to soldering or brazing with the electrodes 8 on the main surface of a printed wiring board 1. The deformation strength of the lead pin 11 is made smaller than the bonding strength of both ends. As a result, the thermal and mechanical stress caused by thermal mismatching between the insulating substrate 4 of the microchip carrier 2 and the printed wiring board 1 can be relieved by the deformation of the lead pins 11. Thereby the bonding destruction of the end-portions of the lead pins can be prevented.

摘要： PURPOSE:To make it possible to cool heating elements efficiently, by a constitution, wherein fresh, cool air hits the approximately entire surfaces of fins on the upstream side and on the downstream side with respect to the flow of the cooling air. CONSTITUTION:Two-phase flow pipe 22 is provided uprightly at the upper part of an evaporating part 20. Several cooling fins 23 are attached to the two-phase flow pipe 22. A two-phase flow pipe 22', which is provided at the upper part of modules 4' on the downstream side, has the length of about twice that of the two-phase flow pipe 22. The provided height of fins 23', which are attached in the two-phase flow pipe 22', are formed at the part about twice higher than the fins 23. When cooling air is made to flow in parallel with the upper surface of heating elements 2, the fresh, cool air hits the approximately entire surfaces of the fins 23 and 23'. In this way, the heating elements in any line are cooled sufficiently. Since the air, which is accelerated with the fins, directly hits the any of the fins 23 and 23', the flow speeds of the air streams passing the fins 23 and 23' become approximately equal. All modules 4 and 4' are uniformly cooled.

摘要： PURPOSE:To improve the effect of cooling, by having fins which are joined with LSIs so that each fin becomes smaller then an LSI when viewed from the upper face of a wiring substrate as well as fins which are mounted removably so that they are widened in the direction of right angles to the flow of cooled air. CONSTITUTION:Numerous LSIs 1 are equipped on a wiring substrate 4 and forced air cooling is performed. Small sized fins A2 are mounted at an LSI substrate and then large sized fins B5 are mounted to the fins A2. The fins B5 are widened among the LSIs 1 adjacent in the direction of right angles to the flow of cooled air. A large number of signal terminals 7 for inspecting the LSIs are installed around the LSIs 1 of the wiring substrate surface. When the LSIs 1 equipped with the wiring substrate 4 are inspected, the large fins B5 are dismounted and a prove for inspection is used so that it comes into contact with the signal terminals 7. When inspected, cooling is performed only by the small sized fins A2, while increasing the amount of cooling air around fin parts. When operated as a computer, the fins B5 are mounted to enlarge heat sinking planes and then very little amount of free air passes among the LSIs, resulting in doing away with useless flowing of air. This approach not only increases heating surface area but also contributes to cooling air effectively by widening the fins through the whole passage width.

摘要： PURPOSE: To attain the system in operation even when a main storage device is disconnected by using an intermediate buffer as a continuous address area as if it were used to be the main storage device if a fault takes place in the main storage device.
CONSTITUTION: If a fault takes place in the main storage off line 131 is made logical 1. In this case, a selector 107 selects a low-order prescribed bit address 122 in a high-order address in the set access address to an address register 101 directly so as to disuse an intermediate buffer address array WAA 3. Thus, the row of the corresponding column of an intermediate buffer WS 4 is selected by the address 122. That is, the WS 4 is accessed directly by the column address 120 and the low-order prescribed bit address 122 in the high-order address among access addresses of the address register 101. Thus, it is possible to use the WS 4 as a continuous address area.

摘要： PURPOSE:To improve the through-out of a memory access of an input/output processing unit by checking an address in a block of access request to select whether the data is transferred in a form of block transfer or transferred directly from a main storage device to the input/output processing unit. CONSTITUTION:Suppose that a desired data does not exists in a buffer storage device (BS) 5 through the access from the input/output processing unit (IOP)2. When the 5th, 6th bits of an address register 3 are ''11'', a control circuit 6 starts a main storage device (MS) 7 so that a desired 16-byte data 34 only is transferred to the IOP2 through a data line 14. Regardless of above processing, the data is reduced to useless, since the 16-byte data 31-33 in the block are not fetched by this channel after the 16-byte data 34 is fetched even if a block 30 of the MS7 is transferred to the BS5. Thus, the direct transfer of the desired 16-byte data 34 only from the MS7 to the IOP2 has far less time.
摘要翻译：目的：通过检查访问请求块中的地址来改进输入/输出处理单元的存储器访问的通过，以选择数据是以块传送形式传送还是直接从主存储设备传送到输入/输出处理单元。构成：假设通过来自输入/输出处理单元（IOP）2的访问在缓冲存储设备（BS）5中不存在期望的数据。当地址寄存器3的第5,6位是“11”时，控制电路6启动主存储装置（MS）7，使得期望的16字节数据34仅通过数据线传送到IOP2 无论上述处理为何，数据被减少到无用，因为即使MS7的块30为块，获取16字节数据34之后，该块中的16字节数据31-33不被该信道取出转移到BS5。因此，期望的16字节数据34仅从MS7到IOP2的直接传送具有远远少的时间。
