Title: Picture data expanding device
Inventor: OOMACHI TAKAO
IPC: G09G1/00
Filed: 1979-12-14
Abstract: PURPOSE: To realize a high-speed expansion process within a system comprising mainly the computers, by receiving the compression data along with the control word from the computers connected directly to each other via the bus and then returning the compression data to the computer after storing it as an extension data.  
     CONSTITUTION: The control part 26 of an expanding device receives previously the transfer word number of the compression data to the input buffer part 23 from the side of the computer in the form of the control word and via the computer bus 1 and the drive receiving circuit 2. This word number is used for the control of the data number when the compression data is transferred to the part 23 and at the same time sent to the expansion control part 28 which controls the operation of the expansion part 24 to be used for the end detection of the expansion process. Thus a control is given to the transfer of the picture element data after an expansion is carried out to the computer memory from the output buffer part 25. For the computer, the compression data is transferred to the DMA from the memoryjust by sending the transfer start command of both the compression data and the picture element data and then returned after an expansion. As a result, an easy and high- speed process is possible for expansion of the picture data  like a use of the subroutine in terms of the sofrtware.

Title: Gear shaft support device for vehicle differential gear
Inventor: NAKAJIMA HIROKAZU
IPC: C22C38/18
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To ensure a long durable life even under the inclusion of foreign matter by forming at least the rolling element of a rolling bearing by use of a steel material containing a specified composition by weight ratio, and determining the residual austenite quantity on the surface layer within a specified range. SOLUTION: For example, the shaft of a differential gear case 7 is supported by a gear shaft support device formed of conical roll bearings 2, 3, and 6. Each part of the conical roll bearings 2, 3 and 6 is molded by use of steel containing C: 0.8-1.5%, Si: 0.4-1.2%, Mn: 0.8-1.5%, and Cr: 0.8-1.8%. When this material is carbonitrided to increase the nitrogen content in the surface layer part, the Ms point (martensite transformation starting point) in the surface layer part is lower than in the inner part. Therefore, when this material is hardened, non-transformed austenite is increased in the rolling element surface layer part, so that the residual austenite quantity in the surface layer part can be set within the range of 20-40% by volume. According to this, the surface peeling can be suppressed to extend the durable life.

Those polymers containing fluorine suffice only by selecting suitably one or at least two kinds by considering conditions wherein the tube is used. For a manufacturing method for the tube, an extrusion molding method is general since, for example, general tubes are constant in a sectional shape.

Title: Actuator
Inventor: MORITA JIRO
IPC: F03G7/06
Filed: 1985-07-23
Abstract: PURPOSE:To eliminate a drive unit, by using a shape memory alloy which expands and contracts in dependence upon temperature variations, for either one of a push-out spring and a pull-back spring to extend and retract an expander in accordance with the elevation and lowering of the temperature. CONSTITUTION:If a pull-back spring 7 is made of a shape memory alloy, it extends since a push-out spring 5 extends to push out an inner member 2. When outside temperature rizes, the shape memory alloy of the pull-back spring 7 retrieves its shape, and therefore the pull-back spring 7 extends, and therefore, push-out spring is compressed to retract the inner member 2. When the outside temperature lowers, the pull-back spring 7 is extended so that the compression of the push-out spring 5 is released, and therefore, the inner member 2 is pushed out due to the extension of the push-out spring 5. Accordingly, an expander A is extended and retracted in association with the elevation and lowering of the temperature, thereby it is possible to eliminate the necessity of a drive unit.

Abstract: PURPOSE:To control the sensitivity of a magnetic sensor, by providing a device controlling the relation of a relative position between a coil for detection and a magnetic core. CONSTITUTION:A bobbin 1 is made of a nonmetallic material such as ceramics, etc. and control parts 2A, 2B threadedly attached with female screws 6A, 6B are fixed at the both ends. Detection coils 3A, 3B are wound around at both ends of the bobbin 1 and magnetic cores 5A, 5B are inserted into the bobbin 1 while holding a spacer 4 in-between.

Abstract: PURPOSE: To prevent occurrence of the click noise at the make of the power source by extracting the DC output of the amplifier via the gate of the MOSFET.  
     CONSTITUTION: With make of power switch 2, pulse b is generated since PNP transistor 6 is turned on earlier than NPN transistor 7. However, the voltage is applied to the gate of MOSFET13 gradually according to the time constant decided by resistance 4 and capacitor 5 plus resistance 14 and capacitor 15 each, and thus FET13 conducts after a fixed time. Accordingly, no pulse b emerges at output terminal 9.

Title: Method for preventing pickup on roll in continuous annealing furnace
Inventor: KAWANAMI YASUO
IPC: C21D9/56
Filed: 1986-07-16
Abstract: PURPOSE:To prevent the growth of pickup on each roll in a heat treating furnace during continuous annealing by regulating the internal atmosphere of the furnace so as to form a carbon film on the surface of the roll. CONSTITUTION:When a steel sheet is heat treated in a heat treating furnace, the internal atmosphere of the furnace is regulated so as to form a protective carbon film of about 1-100mum thickness on the surface of each roll in the furnace. The concn. of CO in the atmosphere is preferably regulated to about 100-2,000ppm, the dew point to <=about -30 deg.C and the concn. of oxygen to <=about 10ppm. Even when iron dust drops from the steel sheet and sticks to the roll, it does not grow to pickup and peels naturally by difference in the thermal expansion of the roll produced by the friction of the steel sheet during passing through the furnace with the roll and a change in the temp. of the furnace.
