Title: Hybrid integrated circuit and its fabricating method
Inventor: TOMIOKA MASANORI
IPC: H01L25/04
Filed: 1994-06-10
Abstract: PURPOSE:To protect peipheral chips and improve strength of a thick film substrate by surrounding, with an annular member, any one of a region including a thick film resistance for function trimming and a region including a changeover ship for adjusting electrical characteristic. CONSTITUTION:An O-ring 4 is bonded to a thick film substrate 1 in such a manner as to surround the region where a thick film resistor 3 is arranged. Since a chip 2 is protected by gel 5 at the time of executing the function trimming, it can be prevented that the chip 2 is touched directly with hand and cut fragments adhere to the chip 2 by the trimming. Moreover, since gel 5 is rather soft but has a thickness of several 100mum or more, the strength of thick film substrate 1 can be enhanced for a mechanical external force.

Filed: 1981-08-21
Abstract: PURPOSE:To make effectively a reflected light passed through a carrier incident to a detector at the front of an analytical element, by arranging a light reflecting layer at the opposit side of an antibody immobilized layer. CONSTITUTION:Glass and various kinds of high-polymer membranes are used as a transparent carrier 2 for immobilization and Al is vapor-deposited at the one side of the carrier as a reflecting layer 3, then an antibody 7 is immobilized at the other side.

Title: Petri-net arithmetic mechanism
Inventor: TSUGANE TAKAYUKI
IPC: G06F17/16
Filed: 1987-05-26
Abstract: PURPOSE:To perform calculation for arriveable problems of the petri-net marking in a short period by carrying out the ignition enable check and lead-out of the next marking to plural transitions at one time. CONSTITUTION:An initial marking state is set at a marking vector register 1 and the input/output function matrices are set at (m) pieces of input/output vector registers 4. Under such conditions, a timing pulse is inputted to an arithmetic timing input 6. Thus (m) pieces of vector adders 2 add simultaneously the vector values of the registers 4 to the vector value of the register 1. The results of these additions are outputted to the adders 2 as the following marking vectors to 1st-m-th transitions. Then (m) pieces of ignition check mechanisms 3 turn on the ignition flags 5, if no negative element is detected out of results of additions of the corresponding adders 2 to show the transition ignition. Thus the calculating time is shortened for additions.

Abstract: PURPOSE: To accurately perform the forecast-control of the roll gap of the edging roll of the rolling mill, by actually measuring the temperature of both edges of the rolled material on the feed-in side, and by arithmetically forecasting the dog bone recovery rate and the spread factor.  
     CONSTITUTION: The temperature of the rolled material P at the points of a specified distance from the side edges are measured by the thermometers 31 installed on the run-out side of the first stand. The thickness and breadth on the run-out side of the first stand are arithmetically operated, and these velues are inputted to the computer 4 which then computes the spread obtained by the rolling work of the horizontal roll of the second stand. Meanwhile, the computer 5 computes the dog bone recovery rate by the rolling work of the horizontal roll of the second stand. These two values are inputted to the computer 6 which then computes the roll gap of the edging roll of the second stand. This value of the roll gap is set in the edging roll gap control unit 8. This operation is repeated with a specified period or for every specified length of the rolled material P.
