Title: Oil-cooled type air compressor
Inventor: KAMETANI HIROCHIKA
IPC: F04C18/16
Filed: 1995-05-25
Abstract: PURPOSE: To prevent the generation of drain after a stop and to suppress rusting and deterioration of oil by a method wherein when an air compressor is stopped, cooling capacity of a cooling means is suppressed only for a specified time before the stop of operation and the temperature of circulating oil is increased to a value higher than that during normal operation. CONSTITUTION: During steady operation, a compressor body 1 receives a rotation power from an electric motor 2 to perform compression operation. Air flows through an air cleaner 63 and a suction throttle valve 6 and enters a compression body 1 through a suction port 11 and is compressed. Oil flowing in a compression chamber through a feed oil port 13 in the middle of compression derives heat from air generating heat and flows through a delivery flow passage 31 after the flow of it through a delivery port 12 and flows through an inlet 32 to an oil separator 3. Further, oil separated by the oil separator 3 flows through a feed oil pipe 53 to an oil temperature adjusting valve 51. A part of the oil flows through a cooling pipe 54 and is fed to an oil cooler 5.  In which case, when a stop button 71 is pressed by a user, a control device 7 indicates the oil temperature adjusting valve 51 to increase a set temperature. The oil adjusting valve 51 increases a ratio of bypassing oil and increases an oil temperature.

And when an operated result is written to the main storage 1, the coprocessor 3, under the control of the main processor 2, directly writes it to the main storage 1 without passing through the main processor 2. Thus, high-speed communication between processors can be executed and the execution by the coprocessor 3 is faster than the main processor 2 and the band width of a bus can be widened.

IPC: C23C2/02
Filed: 1984-06-20
Abstract: PURPOSE:To bake satisfactory an inhibitor in the stage of connecting strips having different sheet thicknesses, coating the inhibitor on one side thereof and subjecting the strips to hardening and annealing by changing stepwise the line speed at the point of the time when the juncture of the strips advances into an annealing furnace. CONSTITUTION:The preceding strip 1 is thin-walled and the succeding strip 2 is thick-walled. The inhibitor is coated on one surface of both strips and is baked by the annealing furnace 4. The inhibitor is first baked in the furnace 4 at a speed V1 at which the inhibitor is adequately baked to the strip 1. The line speed 6 is stepwise decreased to V3, V4 when the juncture 7 between the two strips 1, 2 arrives at the inlet 4a of the furnace 4. The speed is finally adjusted to the baking speed V2 of the inhibitor suitable for the strip 2. The inhibor is thus satisfactorily stripped from the strips in the stage of stripping said inhibitor after galvanization.

Abstract: PURPOSE: To accomplish stoppage of the manuscript at the accurate position by lowering a stopper tooth on the center shaft with a margin of free movement vertically or dipicting an arc to the direction in which the manuscript advances.  
     CONSTITUTION: A first shaft 15 fixed to a hanger 20 is run through the end of a bracket 14 having a stopper tooth 3C on the back of the tip thereof and the second shaft 16 in the proximity of the tip.

Title: Magnetic memory cell and magnetic thin film
Inventor: TSUDAI AKIHIKO
IPC: H01L43/08
Filed: 1990-05-18
Abstract: PURPOSE:To perform fast write and erasure and fast access of data by providing a heating circuit to heat magnetic thin film locally, and a readout circuit consisting of a magneto-resistant element whose resistance value is varied by the readout circuit and the magnitude of an applied magnetic field and a transfer gate. CONSTITUTION:The magnetic thin film 18 is magnetized uniformly in a direction perpendicular to a film plane in an initial state. When the data is written, a signal is inputted to a lead wire 28, and a switching transistor 14 is energized. Thereby, a temperature at a part of the magnetic thin film 18 coming in contact with an exoergic element is increased by receiving heat from the element, and the coercive force and magnetic anisotropy of the heated part of the magnetic thin film are decreased, and the reversal of magnetization at the part occurs by the function of a demagnetizing field from neighboring magnetic thin film. Also, the erasure of the data is performed similarly, however, a write mode or an erasure mode can be selected by controlling heat input and heat input time. Also, the readout of written data is performed by energizing a transfer gate 16 and reading a resistance value between the lead wires 24 and 26.
