Title: Parallel controller for plural pcs
Inventor: YOSHIKURA FUYUHIKO
IPC: G05B19/05
Filed: 1990-03-24
Abstract: PURPOSE:To attain the maintenance and the inspection with no consciousness of the relationship between the corrected or inspected areas of a program and a programmable controller(PC) by providing a storage contents means which outputs the storage contents of a storage means in response to the judgement of a signal name judging means and the set-up of a condition setting means. CONSTITUTION:A storage contents output means M4 of each PC outputs the storage contents of a storage means M2 in response to the set-up of a coupling condition setting means M1. Therefore if a certain coil block is already read out of a program, the means M4 outputs the storage contents in consideration of the set coupling conditions. As a result, the precedent or next coupled PC reacts an output request and outputs its own stored program in place of the hitherto output PC at a part where a program covers both PCs in accordance with the set-up result of the means M1. Thus no consideration is required for the coupling relationships among PCs in a designing task.

Abstract: PURPOSE: To realize a high-speed function test, by delaying the expected value transmission timing by an arbitrary time for the input pattern signal transmission timing and by synchronizing the output pattern signal and the expected value signal with each other.  
     CONSTITUTION: Pulse generating circuit 10 is set to a frequency n-number times as high as timing signal T o  of the pattern signal of inspected circuit 9, and this pulse signal ϕ is 1/10 frequency-divided through frequency dividing circuit 11 to form input pattern transmission timing signal T o . This pulse signal ϕ is divided into n in respect to space through counter circuit 12 and is made into timing signals, which are delayed by one period of timing pulse ϕ for one another successively, through gate circuits G 20 WG 22 , and timing signal T p  selected by selecting circuit 13 is used as an expected value transmitting timing signal. Thus, the input pattern is transmitted by timing signal T o , and the expected value signal can be transmitted by timing T p  delayed by an arbitrary time, so that the output signal and the expected value signal can be adapted to each other, and consequently, a high-speed function test can be realized.

Title: Method of reinforcing cu-ni-sn alloy
Inventor: NAKANISHI TERUO
IPC: C22C9/00
Filed: 1979-06-14
Abstract: PURPOSE: To improve the spring property, etc. of a Cu-Ni-Sn alloy in its manufacturing process, by heating the alloy into a prescribed two-phase balancing temperature region to anneal the alloy before its cold working to change the structure of the alloy.  
     CONSTITUTION: In manufacturing an alloy comprising 3W25wt% of Ni, 3W10wt% of Sn and the rest of Cu and unavoidable impurities, the alloy is heated into a two- phase balancing region in the range of 650W750°C of the ternary equilibrium state diagram of the alloy so that the alloy is annealed before cold working. After the cold working, age-hardening is effected if necessary. Because of the annealing, the second phase of the matrix of the Cu-Ni-Sn alloy is finely dispersed to greatly enhance its mechanical strength, especially its spring limit value. The shaping properties of the alloy such as the bending property are almost equal to those of a conventional similar alloy.

Title: Field effect transistor
Inventor: KAWAI SHINICHI
IPC: H01L29/78
Filed: 1988-03-31
Abstract: PURPOSE:To alleviate an electric field intensity, and obtain a field effect transistor having characteristics excellent in punch-through and avalanche breakdown, by forming a drain separated from an intrinsic channel region, and forming an additional drain connected with the drain and facing a gate electrode. CONSTITUTION:A drain is arranged separated from a gate electrode 4. In a region being in contact with a channel layer except an intrinsic channel region 12, an additional drain 8 with the same potential as a drain 7 is arranged, so as to interposed a protective oxide film 5 therebetween. Thereby the electric field intensity of a shallow region in the vicinity of drain is decreased. The electric field intensity of a channel layer just under a gate electrode 4 in the vicinity of drain is released as compared with the case where the interface between an gate oxide film 3 and the gate electrode 4 and the interface between the protective oxide film 5 and the additional drain 8 have a sharp angle, because the above interfaces form an angle of 180 deg.. Therefore avalanche breakdown does not occur and punch-through can be prevented, even in the case where an field effect transistor is formed on a substrate whose impurity concentration is large.
