Title: Double row rolling bearing device
Inventor: ISHIMARU AKIRA
IPC: F16H57/021
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To eliminate elements making the working of an outer ring troublesome by forming a cutout part on the end edge of the opposite side to the end edge in the axial direction of the other outer ring element within both end edges in the axial direction of one outer ring element, and providing a means for fixing the other outer ring element to a housing. SOLUTION: An outer ring 21 constituting a double row rolling bearing device 20 is constituted by combining together a pair of outer ring elements 22a, 22b. Within the outer ring elements 22a, 22b, the end edge on the opposite side to the one of the other outer ring element 22b end edge in the axial direction of both end edges in the axial direction of the one outer ring element 22a is formed with a cutout part 23 in the diametral direction so as to extend from the inner circumferential face of the outer ring 21 to the outer circumferential face. Because the cutout part 23 is formed simultaneously with the other part by forging to make an intermediate raw material, new process is unnecessary.  The other outer ring element 22b is respectively integratedly formed with a fitting flange 24 as a fixing means on the outer circumferential face and a circumferential part 25 on the outer end part. Hereby, a bearing device of low price and high reliability can be provided.

Abstract: PURPOSE: To cook food appropriately with a simple operation, by changing the cooking conditions for each kind of menu stored in memory of a programming unit for cooking with reference to the input from a means for detecting the weight of food to be cooked and heating characteristics in respect of the weight.  
     CONSTITUTION: In carrying out cooking program No.1, container 13 is at first placed on table 12 in cooking chamber 11. When keys RECIPE, 1, WEIGHT on key board 1 are pushed in the above state, digital electronic control unit 18 stores the weight of container 13 from the signal afforded from weight detecting circuit 6 and displays it in indicating section 2. Subsequently, when keys WEIGHT, START are pushed after putting food 10 to be cooked in container 13, control unit 18 calculates the net weight of food 10 by subtracting the weight of container 13 and displays it in indicating section 2. Then, microwave oscillator 3 is set into operation to start heating with reference to the heating characteristics to the net weight and correcting the timer time of program No.1. Since, in accordance with the above arrangement, pre- stored cooking program is corrected automatically with reference to the weight of food to be cooked, it is enabled to cook food appropriately with a simple operation.

Title: Production of polyimide sheet
Inventor: FUIRITSUPU ANTONII BOODEN
IPC: B29C35/02
Filed: 1990-04-13
Abstract: PURPOSE: To change the shape of a sheet permanently to that of a cushion sheet by a method wherein the sheet is sucked onto the surface of a die by the effect of a vacuum to give a desired shape to the sheet and then the die and the sheet are set in a gas-containing autoclave to be subjected to autoclave treatment. CONSTITUTION: A sheet 1 of polyimide to be shaped is set on a shaping surface of a shaping die 2 and the end edge of the sheet is sealed to the die. A vacuum is effected between the die surface and the sheet to draw the sheet into contact with the die surface so that a desired shape be given to the sheet. Next, the die and the sheet are set in a gas-containing autoclave, with the vacuum left to be effected, and the autoclave is closed. Thereafter the temperature inside the autoclave is raised to about 150-250 deg.C in conformity with the thickness of the sheet and the pressure therein is raised to 5-15 bar. After these temperature and pressure are maintained for 3-15 minutes, the temperature is lowered to 25-125 deg.C while the pressure is maintained. Then, the pressure is lowered and a shaped sheet 5 is removed from the die.

Title: Disk device and monitor value preservation control method in the same device
Inventor: HIRANO MASAKADO
IPC: G11B5/012
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of a performance by a wasteful monitor value preservation processing. SOLUTION: When an even becoming a monitoring object is generated, a CPU 10 increments concerned monitor values being in a monitor value storage area 121 secured in a RAM 12 and also sets a flag 122 in order to indicate that the change of monitor values is generated. Moreover, when the request of a monitor value preservation processing is occurred in this device or the outside of the device and the CPU 10 receives it, the CPU 10 checks whether a flag is set or not and when the flag is set, the CPU 10 executes the monitor value preservation processing preserving the content of the monitor value storage area 121 in the monitor value preserving area secured in the system area of a disk 1 by regarding that either of monotor values in the monitor value storage area 121 is changed.  In the contrary, when the flag is not set, the CPU 10 progresses to a next processing without executing the monitor value preservation processing.

Title: Method for protecting data transmission and device for ciphering or deciphering data
Inventor: BUER MARK L
IPC: G09C1/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the cost in terms of size though the cost of hardwares is increased and to accelerate a ciphering speed by circulating three ciphering stages for five times and extracting final output from a first ciphering stage in a sixth cycle. SOLUTION: An exclusive OR XOR gate 505 takes the exclusive OR of the input of plain sentence data and an outputted previous cipher sentence and outputs it to a multiplexer 510 and an input register 515. Then, the three ciphering stages of cycles 520, 525 and 530 are circulated for five times and the final output is extracted from the first ciphering means 520 in the sixth cycle. In this case, the multiplexer 510 tracks the number of times of the cycles and judges whether data sent to the input register 515 are plain sentence input 500 or a final cipher sentence. In the case of the final cipher sentence, an output register 535 loads output from the ciphering stage 520 and prepares it as the output 540. In such a manner, since the three ciphering stages are required, the hardware cost is increased, however, reduction is performed in terms of the size and the speed is accelerated.

Title: Medicine image printer
Inventor: WOJCIK TIMOTHY JOHN
IPC: H04N1/393
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To print a fixed number of pixels on various sizes of media without a big additional expense by a method wherein when a second size of medium is greater than a first size of medium in a line scanning direction, a pixel clock is operated at a pixel clock speed smaller than that of the first pixel clock. SOLUTION: A timing pulse of a beam 132, that is, a continuous time is determined based on a speed of an image block. There are several fixed frequency pixel clocks in a device 5. Each of the pixel clocks has a specific frequency and an adequate pixel clock is selected by a main computer device 148 corresponding to an operator command. In a high resolution mode, the pixel clock is operated by a control compensation circuit 122. When a medium is great in a page scanning direction, the number of lines is increased. When it is great in a line scanning direction, a pixel clock speed is varied by controlling the pixel clock. As a result, it is possible to prevent the device from being complicated.
