Title: Magnetic shielding section
Inventor: KAWAMATA SHUICHIRO
IPC: H05K9/00
Filed: 1989-05-24
Abstract: PURPOSE:To enable effective magnetic shielding by using a rod material having resistivity of a specific or lower value and by constituting a polyhedron having 6 or more faces forming a one-turn loop whose ratio of total electric resistance and inductance is not more than a specific value as a component. CONSTITUTION:A rod material is used which is mainly composed of either of gold, silver and aluminum and whose resistivity at 20 deg.C is not exceeding 3X10<-8>OMEGA-m to constitute a one-turn loop whose ratio of total resistance (R) and inductance (L) is at least 1500. According to calculation, if F/L is 1500 or less, interlinkage flux can be screened 99% or more against an impact current of 5X20musec due to lightning discharge, etc.; however, if it exceeds 1500, interlinkage flux increases rapidly. Therefore, if a polyhedron of six or more faces is formed by using a material 11 additionally to the basic loop 10, effective magnetic shielding can be realized.

Abstract: PURPOSE:To hold the inside of a circuit in a constant initial state even when a voltage of a power source terminal has dropped, by combining and connecting a transistor (TR) operated by a prescribed threshold, in a complementary insulating gate field effect TR device. CONSTITUTION:When a potential VC is applied to a power source terminal V0 in a transient state, a contact 3 has a potential V1 until a power supply voltage becomes a potential VA (a threshold voltage VT of TRs M6, M8, M10-M16) from V1, and when the power supply voltage further rises to the VC side from VA, said contact is varied in a state of the power source -VT therby, contacts 4 -7 are varied, respectively, and the contacts 6, 7 become the potential VC and V1. When an input signal IN is inputted, the contacts 3-5 are not varied, but the contacts 6, 7 are varied as a state B'. In this state, when the power supply voltage becomes below VD, said contacts become a state C', the TR M12 becomes on, and the contact 6 is varied to the power source potential. Thereafter, when the power supply voltage rises, the contacts 6, 7 coincide with an initial state when the power source is applied.

Title: Method for measuring position of moving robot
Inventor: SUGIYAMA HISAYOSHI
IPC: G05D1/02
Filed: 1993-05-31
Abstract: PURPOSE:To enable a robot in action and a still robot to know their absolute positions even if the still robot is displaced in stand still position. CONSTITUTION:Still robots 2 and 3 measures the distances L1 and L2 of the robot in action at a start point P1 from themselves and the directions. For example, the still robot 2 measures the distance L3 from the robot 1 in action at an arrival point P2 and the distance when neither of the still robots 2 and 3 is displaced in stand still position when the robot 1 in action reaches an arrival point P4. The difference of the measured distance from the initial direction is calculated to obtain the angle theta1 of the still robot 2 to the robot 1 in action at the points P1 and P4. The still robot 2 calculates the movement distance and action of the robot 1 in action on the basis of the distances L1 and L3 and angle theta1 and sends them to the robot 1 in action. The robot 1 in action adds the movement distance and direction to the absolute position at the start point P1 to recognizes its absolute position at the arrival point P4.

Title: Actuator for optical head
Inventor: MATSUMOTO HIROYUKI
IPC: G11B7/09
Filed: 1988-05-26
Abstract: PURPOSE:To improve responseness by fixing a focusing drive coil on the end face of a movable part in the focusing direction. CONSTITUTION:The focusing drive coil 15 is fixed on the lower end of a cylinder part 13. Since the magnetic flux of permanent magnets 4, 5 is penetrated into the coil 15, the movable part 12 can be driven in the axial direction of a guide shaft 2 by controlling current. Since the coil 15 is arranged on the lower end face 13a of the cylinder part 13, the winding diameter of a pair coil can be reduced as compared to a case winding it around the outer periphery of the cylinder part 13, and since the coil 15 is fixed on the movable part 12 only at its upper end face, radiating efficiency is improved and a wire material with a comparatively thin diameter can be used. Thus, the responseness can be improved.

Title: Inverter controller
Inventor: ASAOKA MASAHISA
IPC: H02P1/30
Filed: 1986-06-04
Abstract: PURPOSE:To reduce the loss of a DC circuit together with application of parts of low breakdown strength, etc. and to improve the economical properties with inverter controller, by using a circuit which uses a switch to perform the short circuit control in a partial period before and after the inverter is started. CONSTITUTION:A short circuit control circuit 5 performs the conduction control of the switching element of an inverter 2 based on the voltage detected by a voltage dividing circuit 4, that is, the short circuit control of a switch 6 based on the output frequency, the voltage control and a prescribed sequence. In other words, the circuit 5 closes the switch 6 before an inverter is started and the voltage applied to the inverter 2 is lowered less than the open voltage levels of full DC series circuit 1a and 1b of a solar battery 1. Thus high voltage is never applied to the inverter 2. Then the voltage less than said open voltage and decided by a load line is applied to the inverter 2 when the switch 6 is opened at an appropriate time point after the start of the inverter 2. Thus it is possible to reduce the loss of a DC circuit and to secure application of parts of low breakdown strength or a general-purpose inverter. Then the economical properties can be improved with an inverter controller.
