Title: Tape tension stabilizer
Inventor: KAWAGUCHI NAOKI
IPC: G11B15/43
Filed: 1989-03-06
Abstract: PURPOSE:To stabilize tape tension and to save the space with simple constitution by changing the warp angle of a tape to the tape guides, while passing, through an gap between tape guides provided on a tension plates, and controlling the tension of the tape. CONSTITUTION:A tension plate 2 is supported freely swivelling around a shaft 2a and energized in a clock-wise direction by a torsion coil spring 6 provided on the shaft 2a. When the tape is threaded through the gaps between tape guides 5 and 5 provided on the plate 2 and the tension of the tape is large, the plate 2 is rotated in a counter-clock-wise direction against the energizing force of the spring 6 and the wrap angle of the tape to the guide 5 is decreased. Then, the tape tension goes down. Oppositely, when the tape tension is small, the wrap angle is increased and the tape tension becomes larger. Accordingly, since the tension is controlled by adjusting spring force and changing the wrap angle in correspondence to the tension, the tape tension can be stabilized with a simple constitution and also the space can be saved.

Abstract: PROBLEM TO BE SOLVED: To obviate wear or the like on a bore surface due to oil dilution when an engine is cold by rotating a fuel injection valve according to a state of engine temperature, and in time of the engine cold as well as after the warmup, strengthening each spray penetrating force at both upper and lower sides from an axis of the fuel injection valve. SOLUTION: A control unit 24 controls a rotating actuator 21 according to a state of engine temperature, rotating a fuel injection valve 10. After the warmup of an engine, a center F of fuel injection is deflected to an upper side of an axis L of the fuel injection valve 10, and thereby a spray penetrating force at the upper side of the axis L is strengthened. Further in time of a stratified combustion, fuel injection takes place at a position where a piston 3 is lowered, but after the warmup, since a temperature in a bore surface 2 is high, fuel stuck to this bore surface 2 is evaporated at once, where by there is no problem on oil dilution at all.  In time of the engine cold, the fuel injection valve 10 is rotated, and the center F of fuel injection is deflected to the lower side than the axis L of the fuel injection valve 10, and the spray penetrating force at the lower side than the axis L of the injection valve 10 is strengthened, whereby such a fear that a fuel spray is stuck to the bore surface 2 is avoided.

Abstract: PURPOSE:To obtain a frequency analyzer which is made small-sized and improved in resolution, by providing one geodesic lens and providing a linear waveguide group in the condensing part of a laser beam. CONSTITUTION:The laser beam going toward the center of a lens 11 from a circle 12 which indicates positions to which lengths from the center of a geodesic lens 11 are twice as long as the focal length of the lens 11 is collimated near the center of the lens 11 and is condensed on a position symmetrical with respect to a point on the circle 12. If the centers of the sectors of SAW electrodes 13 are placed on the circle 12, the laser beam has a plane wave shape near the center of the lens, and electrodes function as a diffraction grating to diffract the laser beam. The angle of diffraction depends upon the wavelength of SAW, namely, the frequency of an AC voltage. The laser beam is condensed when passing the latter half part of the lens 11 and reaches the entrance of a linear waveguide group 14 on the circle 12. The laser beam is not diffused by the waveguide group 14 but the angle of diffraction is extended, and it is detected by a detector array 8 to obtain frequency analysis of the AC voltage. Thus, the frequency analyzer which is made small-sized and has the resolution improved is obtained.

IPC: B29K105/24
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To make an ultraviolet laser unnecessary and enhance a positioning accuracy and further, dispnse with the complicated control of an optical system by providing plural light-emitting points at an equal distance from the surface of a photosetting resin, and moving the light-emitting points relatively to the surface of the photosetting resin to scan with an emitted light. SOLUTION: An array of light-emitting diodes 2 are connected to a power supply 4 through a switch 6, and are selectively turned on/off one by one to be emitted to the surface 16 of a photosetting resin 12 contained in a container 10. In addition, an X-Y positioning mechanism 8 drives the light-emitting diodes 2 on an X-Y plane distant as specified from the surface 16. Further, the container 10 is moved in the X and the Y direction using a container drive means. Thus the light-emitting diodes 2 are controlled by the switch 6 to set an arbitrarily selected part of the surface 16. In this case, no mirror is used, so that the control of an optical system is no longer required, and also the use of an ultraviolet laser is unnecessary. Further, no pincushion error occurs and therefore, the positioning accuracy is increased.
