Title: Projecting method toward dome screen
Inventor: KASAHARA MAKOTO
IPC: G03B37/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To make obtainable a video whose distortion is small the same as a case that a projector is installed at the center of a dome even when the projector is installed at any position by reflecting a light beam to be projected by using an aspherical mirror, changing the angle thereof and correcting the distortion of a projected picture. SOLUTION: By the projection lens L of the projector arranged at the position other than the center of the dome having a spherical surface, the video of an original picture P is projected on a dome screen DD. By reflecting the light beam to be projected by using the aspherical mirror M and changing the angle thereof, the distortion of the projected picture is corrected. That means, the light beam emitted from the lens L is reflected by the mirror M in order to reproduce the projected picture so that a viewing angle by which the respective pictures P1'-P3' of the projected picture projected on the actual dome screen DD are watched from the dome center(spherical center) OO1 becomes equal to a viewing angle by which respective object points P1-P3 on the original picture P are watched from the lens L on a virtual dome screen D.

Title: Call setup control system for isdn terminal equipment
Inventor: OZEKI SHINICHIRO
IPC: H04N1/32
Filed: 1991-07-03
Abstract: PURPOSE:To avoid useless call setup operation and waste of a communication cost by implementing the call setup procedure only when plural information channels in use are idle. CONSTITUTION:A B-channel operating state monitor means 2a is arranged in an ISDN interface section 2 and always monitors the B-channel operating state of other terminal equipment on a same subscriber line. A B-channel state flag 4a is arranged in a system memory 4 to indicate the result of monitor of the B-channel operating state monitor means 2a at all times. While an outgoing terminal equipment checks an idle state of a B-channel at an outgoing call, a called terminal equipment checks the idle state of the B-channel at the arrival of a call and executes a prescribed setup means with an opposite terminal equipment only when plural operating B-channels are idle. Thus, in the case of outgoing and incoming, when plural B-channels in use are not idle, since the setup procedure is not executed, the useless call setup operation and the waste of communication cost are avoided.

Title: Testing device of actuator
Inventor: MATSUBARA TAKEHIRO
IPC: G05B23/02
Filed: 1983-10-07
Abstract: PURPOSE:To attain highly reliable test of an actuator without malfunction by connecting a current limiting resistor, a resistor parallel with a contact for short-circuiting the current limiting resistor and a by-pass circuit connected to the parallel resistor in series between both the ends of a connection body for an actuator and a power supply. CONSTITUTION:If the by-pass contact 23 is closed, actuator driving current does not almost flow into the by-pass because the current limiting resistor 28 is connected. Subsequently, a short-circuiting contact 29 is closed to check normality between the collector and emittor of a transistor (TR) 21a. Then, the contact 29 is opened, a test pulse signal is generated from a pulse generating circuit 24 and a semiconductor switch 25 is turned off with a pulse. Consequently, the TR21a also is turned off in accordance with an input pulse, and when the TR21a is off, the actuator driving current is made flow into the bias circuit. The change of the current is detected by a current pickup 26. Thus, the normality of the bias circuit is checked at the test of the actuator driving circuit in operating.

Title: Power amplifier
Inventor: KASHIWA HIDEAKI

Filed: 1986-08-12
Abstract: PURPOSE:To realize low noise and high efficiency of an amplifier by connecting an audio signal in opposite phase and a carrier signal in phase, a balanced transformerless (BTL) fashion and connecting a capacitor in parallel with a load. CONSTITUTION:In extracting a pulse signal subjected to power amplification via a low-pass filter 5, a low frequency output signal similar to an audio input signal from which a signal component corresponding to a carrier signal is eliminated is fed to one terminal of the load. In extracting the signal via a low-pass filter 5', since the signal passes through an inverting circuit 8, the low frequency output signal of opposite phase is fed to the other terminal of the load. That is, because of BTL connection, a low frequency signal having a double output voltage is extracted across the load. Then the signal through the low-pass filters 5, 5' is fed back to preamplifier circuits 1, 1' via feedback circuits 6, 6'. Further, a leaked carrier signal component after the low-pass filters 5, 5' is cut off by a capacitor 9 connected in parallel with the load 7.
