Abstract: PROBLEM TO BE SOLVED: To allow the viewer to view a display video image easily to see at a just front side or the like even when its head is turned by moving an imaginary image so as to avoid the imaginary image from tracing a change in the head direction when the head direction of the viewer is changed. SOLUTION: A moving lens 12L and a fixed lens 13L form a left eyepiece optical system 14L to lead a video image light of a left LCD11L to a left eye EL of a viewer on which an HMD(head mounted display) is mounted. A moving lens 12R and a fixed lens 13R form a right eyepiece optical system 14R to lead a video image light of a right LCD11R to a right eye ER of viewer. The viewer views an imaginary image of the displayed video image by viewing the LCD11L, 11R via the left right eyepiece optical systems 14L, 14R. The HMD1 detects a direction of the head of the viewer to move the moving lenses 12L, 12R in response to the detected head direction thereby moving the position of the imaginary image. In this case, the moving amount of the moving lenses 12L, 12R is adjusted so as not to cause a change in the absolute position of the imaginary image.

Title: Forcible discharger for dc link capacitor
Inventor: USHIYAMA HISAYA
IPC: H02M7/48
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent wasteful power consumption of a high-voltage battery by deciding the presence or absence of melting of a discharge relay contact based on a drop ratio of a DC link voltage during and after discharging of a DC link capacitor during discharging and after the discharge is stopped, thereby effectively sensing contact melting of the discharge relay and inhibiting an inverter operation. SOLUTION: When a motor controller 2 for controlling an inverter senses OFF of a main switch SW1 according to a voltage of an A terminal, the controller 2 stops an output of a control signal Ref to a switching circuit 1 to stop a motor control. Then, after a main relay MS1 is turned OFF, a discharge relay MS2 is turned ON, stored charge of a DC link capacitor C is discharged via a resistor R, and when a detected value of the DC link voltage by a voltage sensor VS becomes a predetermined voltage or less, the relay MS2 is turned OFF. Here, the presence or absence of the contact fusing of the relay MS2 is judged based on a drop ratio of the link voltage during discharging and after stop of the discharge of the capacitor C.
