Title: Cooling structure of semiconductor element
Inventor: ISHII YOSHIYUKI
IPC: H01L23/44
Filed: 1987-05-18
Abstract: PURPOSE:To simplify a process and to perform effective cooling, by sealing a fluorine group coolant in a package and concurrently performing airtight sealing of the package. CONSTITUTION:A fluorine group coolant is hermetically sealed on a reduced pressure state in a structural body formed by mounting a cap airtightly on a package. For example, a semiconductor element 1 is connected with wiring electrodes housed in an inner room 3A of the package 3, through a brazing material 2. The package 3 and the cap 5 are coupled airtightly through the brazing material to be formed unitedly. A fluorine group coolant 4 with a boiling point of 102-253 deg.C, comparatively high, is sealed on a reduced pressure state in the inner room 3A of the package 3. If the coolant with the boiling point of 102-253 deg.C is sealed in a container just at the boiling point, the sealed-in coolant is supercooled at a room temperature after its hermetical sealing process and so pressure in the container is reduced. Since the boiling point of the coolant is also lowered and hence said coolant is easily vaporized by heat generation in an integrated circuit element, effective cooling can be performed by the use of heat of evaporation.

Title: System containing processor
Inventor: SAKAMURA TAKESHI
IPC: G06F13/374
Filed: 1988-05-18
Abstract: PURPOSE:To easily decentralize the processing load for a large quantity of data and to cope with a real-time data processing request by performing the decentralized bus arbitration and the plural-level bus arbitration. CONSTITUTION:A system bus owns the decentralized bus arbitration and the 3-level bus arbitration priority. Thus the even bus arbitration is realized among boards by the decentralized bus arbitration and the load can be easily decentralized in a processing field of a large quantity of data. While the bus application is interrupted in an emergency by the 3-level bus arbitration priority. Thus it is possible to cope with a bus application request of a higher priority degree and also to a real-time data processing request.

Abstract: PURPOSE:To restrain a delivery pressure within a predetermined constant pressure by constituting so that contact between a motor brush and a commutator is brought into a non-contact state by a pressure-actuating device in the case where a pressure of a liquid delivered from a liquid pump exceeds a constant pressure. CONSTITUTION:When brushes 11A, 11B are electrified to feed an electric current to a commutator 7 so as to drive a motor-driven pump P, an electric motor A is rotated by a magnetic line of force due to a magnetic field and an electric current flowing in an armature 8. In a liquid pump B, because of this rotation, an inner rotor 15 and an outer rotor 16 mutually rotate to pressurize a liquid drawn into a pumping chamber 17 through a liquid intake passage 18A for delivery from a liquid delivery passage 18B. When a pressure of a liquid flowing through the inside 1A of a housing 1 exceeds a preset pressure, a partitioning body 21 for receiving this liquid pressure via a pressure introduction passage 25 moves upward against a spring 28. Accordingly, the brush 11B is separated from the outside periphery of the commutator 7 to stop the electric motor A.

IPC: G01F1/56
Filed: 1985-05-31
Abstract: PURPOSE:To make it possible to automatically measure the flow amount of raw milk from the outside of a milk pipe, by winding a coil around the outer periphery of the passage of a non-conductive pipe through which a liquid like raw milk flows and passes and measuring the flow amount of the liquid by detecting the change in the inductance of the coil due to the liquid passing through the passage. CONSTITUTION:A pipe 1 is the non-conductive one used in the milking unit of a pipeline type milker and an enamel wire or a plate wire is wound around the outer periphery of the pipe 1 to form a coil 2 while a condenser 3 is connected between both terminal parts of the coil 2. When a current is supplied to the coil 2 and raw milk is passed through the pipe 1, the inductance of the coil 2 changes and, therefore, this change is detected to catch the change in the flow amount of raw milk. Concretely, the change in inductance is caught as the change in resonance frequency.

Filed: 1988-05-17
Abstract: PURPOSE:To selectively perform the frame and field accesses by using a 1st means which performs a frame access with the highest rank bit of an X counter and a 2nd means which decides an odd or even field access with said highest rank bit. CONSTITUTION:A picture memory which stores a picture of (512X512) picture elements, for example, has a constitution of the double value in the X direction and 1/2 value in the Y direction, i.e., (1,024X256) picture elements as shown by (1). Then the picture data of (1) is stored as shown by (3) and the picture is processed. Thus the left and right halves of the picture show the odd and even fields respectively. Therefore a field access is secured when an access is carried out as shown in (4). This field access is utilized to transfer the data on each field as a block. Thus a frame picture is easily obtained. As a result, both field and frame accesses and the 2-field continuous accesses are attained with use of a simple address control circuit only.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To reduce noise, to economize power, to prevent a sheet martial from being curled and to improve stacking performace for the sheet material by actuating a cooling means synchronizing with a feeding path switching means. SOLUTION: A flapper 14 functioning as a feeding switching means selectively guides the sheet material to a 2nd feeding path 12 or a 3rd feeding path 13 from a 1st feeding path 11. A fan 20 functioning as the cooling means is actuated synchronizing with a slenoid for switching the flapper 14, and arranged to send air to a curved feeding path part from the flapper 14 to the 3rd feeding path 13. Therefore, the fan 20 is actuated only when the sheet material passes through the curved feeding path, where the sheet material is easily curled, from the 1st feeding path 11 to the 3rd feeding path 13, so that the operation time of the fan 20 is made minimum. Therefore, the noise is reduced, the power is economized, and further the sheet material is prevented from being curled so as to improve the stacking performance for the sheet material.
