Title: Constant current source circuit
Inventor: MUROI YASUAKI
IPC: G05F3/26
Filed: 1990-10-25
Abstract: PURPOSE:To allow the circuit to supply a large current even when a component occupied area is small by branching a current of a constant current source with a circuit comprising a MOS transistor(TR) and a bipolar TR. CONSTITUTION:With a control signal IN set to an 'L' level, an output of an inverter 18 goes to 'H' and a MOS TR 17 is turned off. In this case, no base current is fed to a bipolar TR 16, which is turned off. Thus, a current from a constant current source 14 is fed to a current mirror circuit 13 and an output current IOUT proportional to a current of the constant current source 14 is obtained from an output terminal 15. On the other hand, with the control signal IN set to an 'H' level, an output of the inverter 18 goes to 'L', the MOS TR 17 is turned on, a base current flows to the bipolar TR 16, which is turned on. Thus, a large output current is controlled without increase in the occupied area of components.

IPC: H01F7/06
Filed: 1985-12-20
Abstract: PURPOSE:To form a non-magnetic layer uniformly to a predetermined thickness and obtain a long-life electromagnet device with improved abrasion resistance and impact resistance by a method wherein a spacer plate is contacted and fixed to the pole contact surface of one of fixed core and a movable core by laser welding and the welded positions are shifted from the pole contact parts between the cores. CONSTITUTION:A spacer plate 5 is put on the movable core side surface of a fixed core 1 and welded by laser welding at a plurality of positions and attached to the fixed core 1. The welded positions 6 are provided on the fixed core 1 and shifted from the parts 7 which are contacted with a movable core 3 when the movable core 3 is attracted by the fixed core 1. Thus, as the welded positions 6 do not exist in the pole contact parts 7 between the movable core 3 and the fixed core 1, influence of the heat accompanying the laser welding is not given to the pole contact parts 7 and the flatness of the pole contact part 7 can be maintained by uniformly formed thin film non-magnetic layer 5a of the spacer plate 5 with a high accuracy. Therefore, adherence between the spacer plate 5 and the fixed core 1 and the adherence between the movable core 3 and the spacer plate 5 can be improved so that excellent characteristics of an electromagnet can be obtained.

Title: Switching circuit
Inventor: NOGUCHI TSUTOMU
IPC: H03K17/687
Filed: 1987-11-13
Abstract: PURPOSE:To stably operate a switching circuit without deteriorating an insertion loss by connecting resistors between the input end of an FET and the earth and between its output terminal and the earth and setting up their resistance values to a value less than a resistance value obtained at the time of turning off the FET and sufficiently larger than a load resistance value. CONSTITUTION:In the switching circuit, FETs Q1, Q2 are connected in series between one input terminal 11 and two output terminals 12, 13 and the resistors R1-R3 are respectively connected between the input terminal 11 and the earth, between the drain source of the FET Q1 and the earth and between the drain source of the FET Q2 and the earth. The resistance values of the FETs at the time of off usually >=100kOMEGA and the resistance value of a load connected between the output terminals 12, 13 is normally 50OMEGA. When the resistance values of the resistors R1-R3 are set up to 5kOMEGA, these values are the smaller than resistance values of the FETs, so that the increment of the resistance values at the time of turning on the FETs can be extremely reduced. Since these resistance values are larger than the load resistance, the increment of the insertion loss can be suppressed.

IPC: G09G1/00
Filed: 1987-11-12
Abstract: PURPOSE: To eliminate the need for complicated circuit constitution and reduce the occupation area of a circuit by generating the start addresses of 2nd and succeeding planes by holding the address of a 1st plane. CONSTITUTION: The resolution of the human eye is not high enough to follow display screens, one by one, which is utilized to hold the start addresses of the 2nd and succeeding planes on a current screen so that a normal display is made on a next screen. Namely, the address of the 2nd plane is generated even by a counter for the 1st plane, so it is stored in a holding circuit 14 with a hold signal at the moment when it matches the start address of the 2nd screen. Therefore, the holding circuit stores the start address of the 2nd plane for the first time at this point and the stored address is used as the start address of the 2nd plane. Consequently, the need for a complicated calculating circuit is eliminated and the controller can be constituted only by the holding circuit.
