Filed: 1989-04-28
Abstract: PURPOSE:To obtain a composition for use in a thick film conductor by making the composition contain organic vehicles, borosilicate glass powder and copper powder, and selecting the grain size and content of the copper powder. CONSTITUTION:An organic vehicle comprises a binder of ethyl cellulose and the like dissolved in terpineol and the like, and the binder component is 3 to 7wt% of the total amount of the vehicle. As borosilicate glass powder one with grain size less than 4mum and softening point 300-500 deg.C is preferable. Copper powders consist of powder of grain size 2.4 to 4.2mum by 50 to 75wt%, powder of grain size below 2.2 by 0 to 50wt%, and powder of grain size above 4.2mum by 0-12.5wt%, and spherical form is effective and more than two kinds of grain size may be used within respective grain size ranges. For example, when powders of mean grain size 0.8; 2.0, 3.0 are used, the range A indicates good adhesive property to the base, the range B indicates good soldering wettability, and the range C good junction property, and the intersection of the three ranges indicates the best mixing ratio. An effective ceramic wiring base is obtained by the composition.

Abstract: PURPOSE: To permit the field-type sensor to locate the sensing position of an object being sensed by arranging a plurality of sensing wires through a plurality of block filters on both sides of an exciting wire supplied with an oscillation output to detect the sensing output every block.  
     CONSTITUTION: Arranged on both sides of the exciting wire 2 supplied with the oscillation output from an oscillator 1 are at least two sensing wires 4a and 4b connected through a plurality of block filters 3, 3.... When the object M to be sensed  passes the sensing wires from 4a to 4b, at a position (b) a difference voltage VA- VB is produced between the induced voltages of the sensing wires 4a and 4b. At a  position (c) no difference voltage is produced, but at a position (d) a difference  voltage is produced. The difference voltage VA-VB is inverted from in-phase to  opposite phase when the object passes in the direction of from (a) to (e), and from  opposite phase to in-phase in the direction of from (e) to (a). This is detected by a  detecting circuit 5 to obtain a phase changing amount, which is superimposed on  the oscillation frequency of the exciting wire 2 and detected in a discrimination  circuit 7.

IPC: H01L29/78
Filed: 1983-06-22
Abstract: PURPOSE:To enable reduction of a bird's beak in size and to facilitate minituarization of the MOS semiconductor device by forming a substance consisting of Si oxide mainly only in a region except element forming regions. CONSTITUTION:A masking substance 22 is formed on a first conductive type Si substrate 21 followed by photo-etching to selectively leave the masking substance 22 only in element forming regions 22a-22c. After the element isolation regions 23a and 23b are etched to the predetermined depth to remove the masking substances 22a-22c, solution consisting of Si compound mainly is spread followed by heat treatment. Consequently, the solution consisting of Si compound mainly changes into substances 24c and 24d consisting of Si oxide mainly to become a stable solid substances. After that, a gate electrode 27 and source and drain regions 28a and 28b are formed. Thus, accuracy in formation of the element isolation region is almost determined by accuracy in etching of the Si substrate 21. If etching of high anisotropy is used, formation in the region to be determined based on the masking substance becomes possible.

Title: Floating point arithmetic unit
Inventor: YAMADA KENJI
IPC: G06F5/01
Filed: 1990-04-28
Abstract: PURPOSE:To increase the floating point arithmetic processing speed by calculating an exponent and a mantissa which are normalized based on the exponent selected by an exponent selector and the mantissa selected by a mantissa selector respectively. CONSTITUTION:When the difference is obtained between the exponents of an optional operand to be computed and an optional operand, a mantissa candidate computing element 13 prepares the mantissa adders/subtractors 13a in number corresponding to the difference between both exponents. Then each adder/subtractor 13a performs the mantissa addition/subtraction operations in all combinations possible for each difference between both optional exponents. The addition/subtraction operations are carried out to the mantissas Fa and Fb of a computed operand Fa2<ea> and an operand Fb2<eb> to be inputted in all possible combinations. A mantissa selector 14 inputs the computed value of each adder/subtractor 13a and selects the computed value of the adder/subtractor 13a corresponding to the exponent difference computed by a subtractor 11 out of the computed values of those addres/subtractors 13a as a mantissa fa. A floating point normalizing unit 15 inputs the an exponent ea selected by an exponent selector 12 and the mantissa fa selected by the selector 14 and then outputs a nromalized exponent er and a normalized mantissa Fr. Thus the arithmetic processing speed is increased.

Title: Method for controlling work feeder
Inventor: JIN EIKICHI
IPC: B21D43/05
Filed: 1992-05-01
Abstract: PURPOSE:To easily reduce the labor and time in an operation by directly transferring each of shafts of a feeder to a target value on a motion curve when the deviation amount of the each of shafts is calculated and the amount is equal or less than the allowabel value at the time of emergency stop. CONSTITUTION:An automatic pressing work system is provided with a work feeder 5 which automatically carry in/out a work to be worked by a pressing machine 1 to/from a specific working position on the pressing machine 1 in accordance with the rotation angle of a crank of the pressing machine 1. The work is carried in/out while being held by iron hands provided opposed to each of two feeders 5. The angle of the crank is detected and displayed by an instrument 4 according to signals from a synchronized originator. When the deviation amount of each of shafts of the feeder at the time of the emergency stop is equal or less than the allowable value, each shaft is directly transferred to the target value on the motion curve. Thus, the operation for returning to a standby point to return to the linked motion after an emergency stop is needless and manual labor and time required for the operation are largely reduced.

Title: Automatic tracing detector
Inventor: SUZUKI KENKICHI
IPC: B23K9/127
Filed: 1985-05-25
Abstract: PURPOSE:To make even a minute variation in weld open beams detectable, by forming a reflecting part into a cone reflector and setting an apex down to a dividing ridge, while making a light receiving quantity of each light receiving element being opposed even by movement in the apex with fine tilting motion of a detecting bar so as to produce a large difference between them. CONSTITUTION:When a detecting bar 4 is tilted in an A direction at an optional angle, a difference is produced in the light receiving quantity between light receiving elements 101 and 103 opposed to each other on one side, but this difference is not produced in the light receiving quantity between light receiving elements 102 and 104 on the other. That is to say, an irradiating state of a reflecting light spot 18 shifts from a uniformness to each of these light receiving elements 101-104 to the side of the light receiving element 101 as a whole, and thereby an irradiated light quantity for the light receiving element 101 is increased, while the irradiated light quantity for the light receiving elements 103 situated at the side opposite to the light receiving element 101 is sharply decreased. And, a relative light quantity difference between these light receiving elements 101 and 103 grows large whereby a control circuit judges that the detecting bar 4 is tilted in the A direction, thus detecting accu racy of the detector is improved.
