Title: Rotary head drum type magnetic recording and reproducing device
Inventor: NISHIHARA KEIICHI
IPC: G11B15/61
Filed: 1988-07-08
Abstract: PURPOSE:To surely detect the roll-in of a tape due to dewing generated on the tape or a cause other than that by detecting the strength of reflected light by a rotary head drum and that of the reflected light by the tape rolled in the rotary head drum. CONSTITUTION:A light emitting part 4 where the rotary head drum 1 is irradiated by light, and a light receiving part 5 to receive the reflected light from the rotary head drum 1 are provided. In case of feeding the tape 3 normally, the light radiated by the light emitting part 4 is reflected by the rotary head drum 1, and is made incident on the light receiving part 5. Also, when the tape is rolled in the rotary head drum 1, the light radiated by the light emitting part 4 is reflected on the tape 3, therefore, the strength is weakened compared with that of the light reflected by the rotary head drum 1. Thus, the rolling of the tape 3 in the rotary head drum 1 can be detected by utilizing both reflected light. In such a way, it is possible to surely detect the roll-in of the tape 3 due to the dewing on the tape 3 or the cause other than that.

Abstract: PURPOSE:To remove strain effect of resin sealing by providing an N type hole element in the center region vertical to <110> passing through the center of a rectangular single crystal of Si which is parallel to a side <110> and the plain (111) and by flowing current vertically or horizontally to the center region. CONSTITUTION:An element 10 is formed on an Si substrate with a necessary circuit and fixed on a metal pedestal 12 and a sealed with the resin 15 after furnishing leads 13. The element 10 takes a single crystal (111) as a substrate plain and, passing through the center, with coordiante axis 16a, 16b parallel to each side, the axis 16 is parallel to (110) or tilts at an angle 60 deg.. Current terminals 17a, 17b are placed opposingly in the N type hole element 11 and the direction of the current is parallel to the axis 16a or 16b. The center of the element 11 is placed on the axis 16a. The element 10 may be rotated 90 deg. against a package 15. In this case, strain distribution within the element 10 due to resin sealing is reversed in signs symmetrically with respect to the center. The hole element 11 placed in this constitution almost nullifies an unbalance current due to the strain applied on the element 10 after the resin sealing.

Title: Power converter and its controller
Inventor: KOYAMA TAKEO
IPC: H02M1/08
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a circuit constituting section, by minimizing the unbalance between electric currents made to flow to a plurality of power semiconductor chips when a power converter is formed by connecting the semiconductor chips in parallel with each other. SOLUTION: Voltage drive elements 50a-50c are operated as one power element by connecting the elements 50a-50c in parallel with each other. When a signal is applied to the gates of the elements 50a-50c, the voltage of the signal is divided through resistors 64 and 65, inputted to the buffers 70a-70c of digital ICs, and turned on/off at a threshold voltage. All of the output signals of the buffers 70a-70c are inputted to an OR gate 71 and, at the same time, to exclusive OR gates 72a-72c. The output of each OR gate is ORed by means of an OR gate 73 and the output of the gate 73 turns on/off a switch element 67 through buffers 74a-74c and a resistor 68. When the element 67 is turned on, the slowest signal is supplied at the time of turning on elements and elements which are quickly turned on are suppressed by the output of the OR gate 73.  Therefore, the turn-on time and turning-off time of the elements can become uniform.
