Title: Electronic apparatus
Inventor: ONO YOSHIMASA
IPC: H02J7/34
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and save space by installing a switching means in a constant-voltage circuit for supplying constant voltage to a driving circuit to allow the constant-voltage circuit to serve also for a charging circuit for supplying constant charging current to a secondary battery. SOLUTION: When the apparatus body is operating, an off signal is supplied to TR35 to turn TR34 and TR32, TR33 off. The voltage of the collector side of the TR31 is equal to the sum (V1+V3) of the constant voltage V1 determined by a regulator 20 and the constant voltage V3 determined by a Zener diode 60. Therefore, this circuit becomes a constant-voltage circuit for driving which supplies the constant voltage (V1+V3) to an output terminal 70. When charging a secondary battery, an on signal is supplied to the TR35 to turn TR34 and TR32, TR33 off. Therefore, the voltage of the collector side of the TR31 becomes the sum (V1+V2) of the constant voltage V1 determined by the regulator 20 and the constant voltage V2 determined by the secondary battery 4.  Meanwhile, the voltage of R51 is fixed at V1 and charging current becomes constant (V1/R51) and therefore this circuit becomes a constant-voltage circuit for charging for performing a constant current charging.

Title: Resin shielding type semiconductor device
Inventor: YASUKAWA AKIO
IPC: H01L23/31
Filed: 1978-07-07
Abstract: PURPOSE: To prevent cracking of a protective film on the surface of a semiconductor element, as well as to prevent from separation of the boundary surface between a resin, and a tab and the element, by plugging up heat-contraction preventing plates in the resin at above and below the element.  
     CONSTITUTION: A heat-contraction preventing plates 6 are buried in a resin 5 at both above and below a semiconductor pellet 3. These plates 6 restrict contraction of the resin by heat, thus reducing the apparent coefficient of linear expansion of the resin 5 as well as shearing force being applied to the boundary between the resin 5, and a tab 2 and the pellet 3. As for the heat-contraction preventing plates 6, materials which have smaller expansion coefficient and larger elastic modulus than the resin 5 has, such as cobal and phosphor bronze are recommended. The thicker the plate 6 is, the less is the shearing stress. A single heat contraction preventing plate 6 can be used either above or below the semiconductor element.

IPC: G03G15/01
Filed: 1984-04-25
Abstract: PURPOSE:To form a dichromatic image of good quality which has sufficient specific-color density and no color mixture by superposing and transferring an original image of a specific color on a P type photosensitive body using an N type photosensitive body in combination and a black image on another P type photosensitive body. CONSTITUTION:Original exposure light is split into three light beams having the same quantity through half-mirrors 24 and 25 with a specific reflection factor and an N type photosensitive body 2, P type photosensitive body 1, and P type photosensitive body 3 which are equal in optical path length from an original are exposed to the light beams respectively. A latent image having a decrease in positive electrostatic charge at a part corresponding to the complementary color of red is formed on the photosensitive body 1 and a latent image of color parts other than red which has no potential at the red part is formed on the photosensitive body 2 which turns synchronously in contact with the photosensitive body and transferred to the photosensitive body 1. Consequently, a latent image of only color with high contrast is formed on the photosensitive body 1 and developed with red toner. On the other hand, the black toner image of a latent image of parts except the red part is formed on the photosensitive body 3 and bothimages are transferred to a form 32 one over another to obtain the dichromatic image of good quality which expresses the red part sufficiently to specific density and has no color mixture.

Title: Fuel assembly for boiling water reactor
Inventor: OKUBO KAZUTOSHI
IPC: G21C3/324
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To suppress the sudden rise of reactivity in the occurrence of an earthquake by shifting the position of the central axis of a D-grid reactor core fuel rod bundle in the direction leaving a control rod. SOLUTION: When a fuel assembly in which the position of a fuel rod bundle 12 is shifted in the direction leaving a control rod 4 is charged in a reactor core, the space between the fuel rod bundles 12 in the adjacent fuel assemblies is narrowed in the side opposite to the control rod 4. Even when a channel box 2 is vibrated to extend the gap width at an earthquake, it never becomes an excessive gap width, and sudden rise of reactivity is hardly caused in the individual fuel assemblies. As another method, the thickness dimension of the side surface of the channel box 2 is set larger on the control rod 4 side and shorter on the opposite side to the control rod 4, and the fuel rod bundle 12 may be arranged so that its central axis is conformed to the central axis of a substantially rectangular parallelepiped formed by the inside surfaces of the channel box 2.
