Title: Manufacture of magnetic metal powder
Inventor: FUJII SHIGEO
IPC: B22F9/22
Filed: 1983-04-25
Abstract: PURPOSE:To obtain an alloy metal powder enabled to control freely a nickel adding amount to hardly generate ramification and to generate no undissolved deposite by a method wherein when gas containing oxygen is to be made to come in contact with suspension of a deposit of ferrous hydroxide and nickelous hydroxide, it is performed by mixing the aqueous solution of a trivalent or a quadrivalent metal salt. CONSTITUTION:After an alkali solution is mixed to a mixed solution of ferrous salt and nickelous salt to coprecipitate ferrous hydroxide and nickelous hydroxide, a trivalent or a quadrivalent metal salt is dissolved. Gas containing oxygen is made to come in contact with suspension of the deposit thereof to generate alpha- oxy iron hydroxide powder containing nickel and a trivalent or a quadrivalent metal, and after filtered and dried, the generated powder thereof is reduced to obtain magnetic metal iron powder containing nickel. For example, after an aqueous solution of sodium hydroxide is added to a mixed solution of ferrous sulfate and nickel sulfate to obtain a deposit, an aqueous solution of chromium sulfate is added, air is blown in the suspension of deposit, and stirred for 6hr to obtain alpha-oxy iron hydroxide powder containing nickel. Then the powder thereof is heated to be reduced, and an alloy magnetic powder is obtained.

Title: Method for extracting mask layout parameter
Inventor: KIMURA TOMOO
IPC: G06F17/50
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To realize a mask layout parameter extraction method that can be speeded up with a simple processing, by obtaining the lengths of resistance lines for indicating the connecting direction of a resistive element, obtaining the widths of the divided resistive elements from respective points, which are used at the time of obtaining the resistance lines and calculating resistance values from the obtained lengths and widths. SOLUTION: Contact orthogonal crossing points P1 and P2 in a resistance rectangle, edge points P4 and P5, an edge orthogonal crossing point P6 and an edge intermediate point P7 are collectively registered as resistance points. A contact orthogonal line and an edge orthogonal line used at the time of obtaining the resistance points and a path for connecting the resistance points and a contact center point along an axis, which is registered as the resistance line are recorded as the final resistance lines. Then, the lengths between the contact center point and the resistance points are obtained so that the lengths of the respective resistance lines RB1-RB9 are measured so as to decide the widths of the respective resistive elements around the contact center point and the resistance points.  The resistance values of the respective resistive elements are obtained from the lengths and the widths of the respective resistive elements.

Abstract: PURPOSE: To prevent the charge for a time required for selection of call reception processing from being imposed to a caller by quickly selecting the call reception processing based on cross reference between a registered telephone number and the call reception processing. CONSTITUTION: A caller number from an exchange 17 is tentatively stored in a caller side telephone number storage area 8a and displayed on the display section fo an operation panel 22. When the number stored in the area 8a is already stored in a list storage area 7a, the call reception mod is judged. When the mode is an automatic reception mode, when the caller side does not send its facsimile signal to a called party, the mode of the caller number is updated into an F/T changeover call reception mode. When the call reception mode is a manual call reception mode and the caller side opens a line before a phone call or sends facsimile data together with a phone call, the mode of the caller number is updated into a mode corresponding to the F/T changeover call reception mode. Furthermore, when the call reception mode is the F/T changeover call reception mode and the caller side makes only a phone speech, the mode of the caller number is updated into the manual call reception mode and when facsimile communication only is made, the mode is updated to a mode corresponding to the automatic call reception mode.

Title: Field-effect transistor
Inventor: MITSUI YASUROU
IPC: H01L29/10
Filed: 1978-06-16
Abstract: PURPOSE: To raise the proof voltage and the output of a field-effect transistor, by making the impurity density of an operating layer as high as 2×10 17  or more per cubic centimeter and setting a low impurity density low near the surface of crystal whereon a Scottky junction is produced.  
     CONSTITUTION: The impurity density near the surface of crystal whereon a Schottky metal is provided is made as relatively low as about 10 17  per cubic centimeter. Therefore, the inverse proof voltage of the gate is 20 V or more, and a depletion layer extends to a point A because of the electric field in the Schottky junction when the gate voltage is zero. Because a layer AA' which is really modulated by the gate voltage has an impurity density of 2×10 17  to 5×10 17  or more per cubic centimeter, the value Gm is very large and the output increases when the drain saturation current is constant. The drain-gate proof voltage in not extremely decreased. The impurity density of the operating layer is made high. The value Gm is raised. The pinch-off voltage is reduced. The output is augmented.

Abstract: PURPOSE:To stabilize the transfer of a slab by previously detecting a thickness, an edging amount, etc., of a hot rolled slab and pinching the slab by a prescribed pressure between upper and lower pinch rolls through a vertically moving press device based on the detection signals. CONSTITUTION:Upper and lower pitch rolls 7, 8 vertically moveble by upper and lower press cylinders 3, 4 and capable of tilting in the width direction of a hot slab 9 are installed, respectively. The lower pitch roll 8 previously waits in a waiting position by a signal, agreeing with a thickness, width, and edging amount of the slab 9; then the slab 9 is pinched between the pinch rolls 7, 8 by vertically moving the rolls 7, 8 concurrently with passing of the slab 9 onto the roll 8.
