Title: Method and device for discriminating front and rear side
Inventor: HAYASHI YOICHI
IPC: G11B5/627
Filed: 1988-01-13
Abstract: PURPOSE:To discriminate the front and rear sides of a magnetic tape over its full length with high accuracy, to make the size of the device small, to reduce the manufacture cost and to save man-hour for the maintenance by irradiating the surface of a recording medium by a polarized light and detecting whether or not the vibrating face of the polarized light is rotated. CONSTITUTION:Since polarizers (polarizing means) 6, 7 are inserted in the optical path of the reflected polarized light from the surface of the recording medium, the light having the same vibrating face as that of the polarized light irradiated on the surface of the medium is shut, for example, but the arranging angle of the polarizers 6, 7 is adjusted. Through the adjustment as above, the reflected light from the magnetic substance coating face is all shut by the polarizers 6, 7 and all or part of the reflected light from the base exposed face or the like transmit through the polarizers 6, 7. Then the transmitted luminous quantity of the polarizers 6, 7 is detected by a photodetection means 8 and the detection level is compared with the level of the reference signal, then the front/rear side of the magnetic recording medium is discriminated. Then the tape 3 placed front side back or rear face winding are checked, the device size is made small, the manufacture cost is reduced and man-hour of maintenance is saved.

Filed: 1981-01-16
Abstract: PURPOSE:To improve the image pickup performance of a body whose image is to be picked up, by permitting a color image pickup device to operate normally when said body is bright or as a high-sensitivity one when dark. CONSTITUTION:When a body whose image is to be picked up is bright, a signal led out of an image pickup tube 5 is processed by video amplification 6, and a processing circuit 7 performs correction and color-signal separation to send its output to a matrix circuit 8, which generates and sends a color difference signal to a color encoder circuit 12, thereby generating a TV signal. The outut of the circuit 6 is detected by a detecting circuit 16 and compared with a prescribed level by a comparing circuit 17 to output a control signal. With this signal, a switching circuit 13 selects and sends the output of a color encoder circuit 9 through an output circuit 14. In this case, an infrared cut-filter 3 is inserted into an optical path, but when the picked-up body is dark, the circuit 17 detects that to send out the output of the encoder circuit 12 through the circuit 13 while the filter 3 is put off the optical path.

Title: Stream lining device
Inventor: NISHIJIMA SHIGEYUKI
IPC: F15D1/02
Filed: 1995-01-18
Abstract: PURPOSE: To constantly unify the flow velocity distribution in the down-stream side no matter how the flow velocity distribution in the up-stream side may vary, by preparing a resistance body, which moves in correspondence to the flow velocity so as to widen or narrow the flow passage, in addition to a tapered flow passage. CONSTITUTION: When the flow velocity distribution at an entrance of a duct 1 is not uniform, in the place where the flow velocity is large, the flow-force acting on a spherical resistance body 3 becomes large. Therefore, the spherical resistance body 3 is pushed up to the narrowest tapered part. Thus, since the gap between a flow passage dividing tapered partition wall 2 and the spherical resistance body 3 is narrowed, the flow rate per unit time is lowered. On the other hand, in the place where the flow velocity is small, the flow-force acting on the spherical resistance body 3 becomes small. Therefore, the amount being pushed up to the narrowest part is small. Accordingly, the gap between the partition wall 2 and the resistance body 3 is hardly narrowed.  Thus, not only the flow rate per unit time is not lowered, but the amount of influx is increased because the flow running the part where the flow-rate is lowered makes a detour. With this contrivance, uniform flow velocity distribution can be obtained at the outlet (side) of the flow passage dividing tapered partition wall 2.

Filed: 1980-01-23
Abstract: PURPOSE:To automatically identify the pin position of the semiconductor device by coating magnetic ink on a part of a package and forming the pin position detecting mark thereon. CONSTITUTION:A visually identifying cutout 2 is formed on the end of the pin P1 side, and magnetic ink 4 is coated on the vicinity of the cutout 2. If the ink 2 is colored, no cutout is necessary.
