Title: High frequency power module
Inventor: KAMISHIRO IWAMICHI
IPC: H01L25/07
Filed: 1994-10-25
Abstract: PURPOSE: To reduce the mounting area by arranging surface fins within the outline of a heat dissipation flange, i.e., a rectangular region, and composing the surface fin of a part of the heat dissipation flange between two grooves extending inward from the circumferential fringe of the heat dissipation flange in parallel with each other. CONSTITUTION: The high frequency power module 10 comprises a rectangular planar heat dissipation flange 1 having major surface secured with a circuit board 2 through a solder 15. The circuit board 2 is provided, entirely on the rear side thereof, with a conductive layer 16 of copper, for example. The heat dissipation flange 1 is provided with two grooves 35 extending inward from three sides thereof in parallel with each other. A part 1 of the heat dissipation flange between two grooves 35 composes a surface fin 8. The surface fins 8 are provided, respectively, on the longitudinal side face and the opposite sides of the heat dissipation flange 1. Since the surface fin does not project to the outside of the rectangular frame region of the rectangular planar heat dissipation flange but located at a lower part within the rectangular frame region, the mounting area can be reduced.

Title: Magnetic recording and reproducing device
Inventor: TSUDA KEIJI
IPC: H04N5/783
Filed: 1985-11-19
Abstract: PURPOSE:To prevent the disturbance of a pattern by using the 1st control signal and a signal obtained by the phase comparison of a reference signal as a variable speed reproduction. CONSTITUTION:When a variable speed reproduction command signal SH from a terminal 21 is inputted to a head control circuit 18, a rotary head pair 10 of the normal reproduction is changed over into a rotary head pair 11 exclusive for variable speed reproduction, a switch 17 is switched from a contact (a) to (b) and a reproduced video signal is extracted. Since a head switching control signal RF1 is fed to a trapezoidal wave generation circuit 15 even at the variable speed reproduction, the head servo system comprised of circuits 15, 16, 19 is controlled by the same signal at the normal reproduction. Since the relation of phase between head switching control signals RF1, RF2 is constant and no phase comparison is required, a phase error signal CV1 of the head servo system at the transition has no change, the head servo is made stable and no disturbance due to the changeover is caused as the head rotation.

Title: Hand-written character recognizing device
Inventor: YOSHIKAWA TAKATOSHI
IPC: G06K9/62
Filed: 1985-11-20
Abstract: PURPOSE:To realize a high recognition ratio by a small-sized recognition dictionary and to recognize the variety of hand-written characters by correcting the shape of strokes of an input character divided into line segments by approximating to a kinked line through the use of information on the vector of an off- stroke. CONSTITUTION:A stroke division part 7 approximates data on hand-written characters from a recognition part 2 to a polygonal line so as to divide into plural line segments, and extracts polygonal points included in the line segments as a feature point with high possibility that the stroke joint may occur when said points are continuously inputted. A dictionary part 9 states a line segment connecting the end point of the former stroke and the start point of the latter stroke among two strokes where characters inputted with a normal strike order and the number of strokes are adjacent. While a correction part 8 sequentially uses detected feature points in the division part 7 as a division point, it divides a stroke, and corrects the shape of the stroke by collating the divided stroke with a dictionary part 9.
