Patent JP-H053634-A (JP)
Title: Battery charging and discharging circuit
Inventor: ITO NAOKI
IPC: H02J7/00
Filed: 1991-06-27
Abstract: PURPOSE:To make it possible to fully charge a battery for power source backup for a load by means of a power supply voltage of a predetermined level supplied to the load. CONSTITUTION:First and second batteries 25 and 28 are connected in parallel through respective serial circuits including reverse-current prevention diodes 27 and 30 and charging resistors 26 and 29 between power supply voltage line L1 and ground level line L2. If a drop in power supply voltage level supplied from a power supply circuit 21 to a load 22 is detected by a voltage monitor circuit 244, then the first battery and the second battery are connected in series between the power supply voltage line and ground level line by the action of a switching circuit comprising an NPN type transistor 33, PNP type transistor 35 and a resistor 36. Each voltage value of the first and second batteries is lower than the power supply voltage but is almost equal to the power supply voltage (2.4 V each) when the first and second batteries are connected in series.

Title: Image synthesis device
Inventor: TOKUNAKA JUNZO
IPC: H04N9/75
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To synthesize a main image with other image by segmenting precisely the main image. SOLUTION: The device has a visual light camera 30 that senses a visual ray, and invisual light camera 50 that senses other than the visual ray, the visual light camera 30 picks up a main image placed on front of a background image to generate a video signal SA, and the invisual light camera 40 picks up the background image and the main image while an invisible ray is emitted onto the background image to generate a contrast signal SB with respect to an image. The contrast signal SB is used for a chromakey signal and the main image signal being a component of the video signal SA is synthesized with a 2nd video signal SC. Since an ultraviolet ray or the like does not transmit through an object (main image) and a contrast image without the main image is obtained, the main image is synthesized with the 2nd image precisely.  Since a back screen is irradiated with an ultraviolet ray, even when a background color of the back screen is in any color or any pattern is in existence, the background image (color and pattern) is not in existence in the contrast signal.

The exclusive OR circit A is a complementary circuit and the power consumption is a current value of a C- MOS level. When Vp of both data Xn+1 and Yn+1 is grounded, a node Np becomes Vp. Accordingly, when the Trc1 is at on state, that is to say, an output Cn of a coincidence detecting circuit of data Xn, Yn is in a ground level, Cn+1 becomes a Vp level. In the event of dissidence of the data Xn+1, Yn+1, a coincidence signal becomes a ground level irespective of Cn. The power consumption of the exclusive NOR circuit also becomes a C-MOS level in the same way.

About half the volume occupied by the molybdenum dioxide forms a bubble 4 unless the uranium dioxide grow the grains in the bubble direction enclosing the molybdenum when the molybdenum dioxide 2 is reduced to the molybdenum 3. Then, the difference in the rate of expansion or contraction between the uranium dioxide and the molybdenum by a difference in the coefft. of linear expansion of both is absorbed by the bubble 4 and, stresses are not generated and the cracks are not formed. The stress corrosion cracking of the cladding pipe and the degradation in the thermal conductivity of the pellets are suppressed in this way.
