Title: Laser beam recorder
Inventor: OKURA MASAYOSHI
IPC: B41J2/44
Filed: 1994-06-27
Abstract: PURPOSE:To provide a laser beam recorder capable of corresponding to the switch of recording density without adding new part and drive mechanism. CONSTITUTION:A ground plan of a rotary polygon mirror and sections of b-b line, c-c line are shown. The rotary polygon mirror is provided with reflection surfaces A, B with curvatures different from each other. In a shown example, the surface A is a plane, and the surface B is a cylindrical surface. When a beam outgoing from a laser light source not shown in figure is deflected by the surface B, and an image is formed on a photosensitive body, a beam size is enlarged compared with the case where it is deflected by the surface A, and the image is formed on the body. Thus, by selecting the reflection surface of the rotary polygon mirror according to the instructed recording density, the beam with the size suitable for the recording density is formed on the photosensitive body.

The circuit 10 works only when the terminal 7 is set at an OFF level when the output 5 is impressed. Then the terminal 7 is changed to an ON level. Thus the switch 3 is opened and then applied again while the terminal 7 is kept in an ON state. As a result, an ON state is delivered to the terminal 7. Thus transistor 10a and 10b are kept cut off with the terminal 8 kept open respectively. Then the terminal 7 is kept ON as it is.

Title: Semiconductor case for surface packaging
Inventor: IKEDA MAMORU
IPC: H05K1/18
Filed: 1989-06-30
Abstract: PURPOSE:To improve patterning rate on a printed wiring board to reduce manufacturing cost by leading all contacts of all external lead terminals with a substrate on four sides in the same direction. CONSTITUTION:The direction of leading a plurality of external lead terminals 2 from four sides of a semiconductor case body 1 are made slant with appropriate angle not perpendicular to the four sides of the semiconductor case body 1 so that the tips of the corresponding external lead terminals 2 are positioned in a line. As a result all pads 3 for mounting parts are directed in parallel to the direction of pattern wiring 5 on a printed wiring board 4 so that the pads 3 for mounting parts do not interface with respect to the direction of the pattern wiring 5. Therefore a pattern wiring region can be largely increased thereby largely reducing the number of wires and reducing manufacturing cost.
