Title: Cooling arrangements for air-cooled computer
Inventor: YANAGIDA TAKEHIKO
IPC: H01L23/467
Filed: 1987-09-02
Abstract: 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.

There, the luminance signal having a great influence on picture quality is sampled at the prescribed period and converted into digital data, on the other hand, the two color difference signals are thinned at prescribed intervals, sampled and converted into the digital data. Consequently, data quantity decreases for the thinning ratio of the color difference signals and the information quantity of a color picture is compressed. Thus, the memory capacity is reduced and at the same time, the transmitting time of picture data can be shortened.

Title: Magnetic field application device
Inventor: HABARA TAKASHI
IPC: G11B5/02
Filed: 1987-08-31
Abstract: PURPOSE:To make it possible to conduct a high-speed switching of large magnetic field as well as to improve the record-erasing characteristics of a photomagnetic device for recording, reduction, and erase by a method wherein a high permeability ferromagnetic cylindrical member, having a wire-wound protrusion on one end of the inner wall, and a cylindrical permanent magnet, arranged in such a manner that its projection is positioned in close vicinity to the internal part of the above-mentioned ferromagnetic member, are provided. CONSTITUTION:As a magnetic path, with which the magnetic flux 8 and 9 generated from the N-pole of a permanent magnet 2 is led to the S-pole in a highly efficient manner on a high permeability ferromagnetic member 3, the upwardly generating magnetic field from the N-pole becomes small. On the other hand, when a current I is applied to a winding 4, the magnetic flux leaks out to the outside from the N-pole in the amount of magnetic flux generated in the high permeability ferromagnetic member by the current I. As a result, bias magnetic field is applied upwardly from the N-pole. The intensity of magnetic field in the upper part of the magnetic pole of the permanent magnet 2 can be selected by adjusting the value of current allowed to flow on the winding 4. Accordingly, the vertical magnetic field of several hundred oersteds can be switched at several MHz at a place separated from the N-pole edge face by several mm.

Title: Memory device
Inventor: OUCHI YASUSHI
IPC: G11C11/406
Filed: 1992-08-18
Abstract: PURPOSE:To embody a high-speed memory device without lowering a memory access time due to a wait for refreshing operation by providing a refreshing controller and a refreshing timer. CONSTITUTION:When a CPU 1 fetches instruction from a memory bank 3, demand for memory access is outputted to a memory controller 2. The controller 2 decodes the access demand and outputs control signal group for reading memory only to the bank 3. The bank 3 reads data according to the signal group and a memory address. In general, a period for reading program of the CPU is shorter than the refreshing period. When the demand for reading instruction is issued from a bank 4 after reading from the bank 3, the refreshing of banks 3, 5, 6 is executed by means of the refreshing controller 7. Consequently, by successively refreshing all memory banks except the bank for demanding memory access, the refreshing period is satisfied with the exception of a particular case.
