Inventor: MASE AKIRA
IPC: H02K19/22
Filed: 1979-10-19
Abstract: PURPOSE:To prolong the life of brush by connecting a commutator for surge voltage absorption between a rotor winding and a slip ring. CONSTITUTION:Slip rings 21, 21' are connected to the both ends of rotor winding 12 constituted by applying winding on pole cores 11, 11'. Then brushes 31, 31' are connected to these slip rings 21, 21' and a regulator 50 is connected to the brushes 31, 31'. In addition, commutator 40 is connected to the both ends of the rotor winding 12. In this way, surge voltage when slip rings 21, 21' and brushes 31, 31' are in ''non-contact'' state, is absorbed into the commutator 40, preventing electric discharge between the slip ring and the brush. Thus it is possible to prolong the life of a brush.

Abstract: PURPOSE: To make it possible to confirm whether or not memory contents retained in a memory unit are correct without increasing memory capacity, by specifying operations at the time when a main power is turned ON and OFF.  
     CONSTITUTION: With main power supply 1 OFF, memory address contents in a fixed area of volatile memory 4 are added together and stored at a specific address except memory addresses in volatile memory 4, and when the feeding of power of main power supply 1 starts, memory address contents in a fixed area of volatile memory 4 are added together and compared with contents stored in the specific address, so that a coincidence or dissidence signal between the both will be outputted by controller 5. Consequently, turning main power supply 1 ON addes contents in the fixed memory address area of volatile memory 4 and the sum is stored at the specific address as data for checking, and when main power supply 1 is turned ON again, power change-over circuit 3 applies the output of main power supply 1 to volatile memory 4 as a substitute for that of reversible battery 2 to add contents at memory addresses in the fixed area and the sum is compared with checking data stored at the specific address; when the both agree each other, a coincidence signal is outputted and when not a read of memory contents is interrupted.

Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To surely provide sufficient bonding strength and reliability in connection using conventional materials and improve high frequency characteristics by making a gate electrode have a double layer structure by forming a high melting point silicide layer on a high melting point metal film. SOLUTION: On an insulating film 2 in the surrounding of an aperture part 3, a gate electrode 7 comprising a high melting point metal film 5 of such as W, Mo, Nb and a high melting point silicide film 6 of such as WSix on the metal film 5 is so formed as to surround a cathode 4. In this case, the film thickness of the film 5 is set to be 0.2-0.5μm and the thickness of the film 6 is set to be approximately 1000-2000 angstrom. Moreover, since electron emission is carried out without heating the cathode 4 by applying an electric field at about 10<6> V/cm or higher between the electrode 7 and the tip of the cathode 4, voltage as low as 30-60 V is sufficient for the gate voltage.  Due to the double layer structure of the electrode 7, an outer terminal can be connected with a pad taken out of the electrode 7 through a wire by wire-bonding and productivity and connection reliability are improved.
