Title: Semiconductor device
Inventor: OZEKI MASASHI
IPC: H01L29/80
Filed: 1982-02-24
Abstract: PURPOSE:To prevent the adverse effect of gate pad potential on channel currents between source-drain, and obviate the degradation of element characteristics by implanting atoms giving no conductivity such as protons to the gate-pad forming region of a high-resistance substrate and forming an insulating layer. CONSTITUTION:The substrate is mesa-etched for isolation, and protons are implanted in the region 5 through an ion implantation method. A source electrode S, a gate electrode G, a drain electrode D, a gate pad 4 and a drain pad 3 are formed after protons are implanted. The conditions of the implantation of protons for forming the insulating layer are acceleration energy of 300KeV and the quantity of douse of 1X10<14>cm<-2> when a GaAs MES FET is manufactured. Such conditions for implantation are changed in response to element characteristics, and a value through which the insulating layer through which the best effect is obtained can be formed is selected. The depth of the insulating layer can be controlled by the energy of implantation.

Filed: 1980-03-07
Abstract: PURPOSE:To make highly accurate and highly reliable measurement by removing the noise component contained in the electromotive force generated from a detecting coil and the noise component out of the signal component and taking out only the signal component. CONSTITUTION:After the electromotive force generated from a detecting coil C is amplified with an amplifier 41, it is inputted to a synchronous rectifying circuit 53. On the other hand, the exciatation current from an excitation current detecting circuit 51 is controlled over phase shifting with a phase shifter 52 so as to assume the same phase as that of the signal voltage and the excitation current, after which it is inputted into the circit 53.

Title: Retrieving system for knowledge expressing frame
Inventor: UEHARA SANPACHI
IPC: G06F17/30
Filed: 1986-02-14
Abstract: PURPOSE:To attain retrieval in a short time even with a large amount of data with use of a prescribed retrieval key, by securing such a system where only the relevant frame can be retrieved via a hash table. CONSTITUTION:A retrieval deciding part 1 decides whether or not the slots in a frame set as retrieval keys form a hash table. If no has table is formed, a conventional retrieving part 2 retrieves all frames individually and successively. At the same time, a fact that a single retrieving action is carried out is recorded to the column of the corresponding slot at a storing area 20 for the retrieving number of data of a frame control data storing device 10. Then, the second decision is carried out by the part 1 when the same slot is requested as a retrieval key. At the same time, the reference is to the frequency and therefore the prescribed value, e.g., '1' is recorded to decide the 2nd retrieving request. Thus the processing is changed not through the part 2.
