Title: Electroluminescence element
Inventor: AOKI YUICHI
IPC: H05B33/12
Filed: 1990-02-22
Abstract: PURPOSE:To improve the luminous efficiency by making the form of conductive micropowders in the current limiting layer of a complex type EL element in a specific form, and contacting electrically to a luminous layer in a point contact. CONSTITUTION:A conductive micropowder is made into particles or a collecting body of particles which have tips. In a structure collecting needle-form crystals radially, for example, the outer size of a needle-form crystal is made 1 to 10nm in the height and the width respectively, and 5 to 200nm in the length. The curvature radius of the parts where the conductive micropowders are contacted to the luminous layer is made less than 5nm. By such a point contact condition, the strength of electric field at the contact parts is increased locally, and thereby the electrons are accelerated to realize a high luminous efficiency.

Filed: 1983-03-14
Abstract: PURPOSE:To achieve stable brazing with high reliability using cheaper brazing materials by a structure wherein a metal layer capable of brazing is formed on the rear surface of a semiconductor element. CONSTITUTION:When brazing a semiconductor element onto a semiconductor element mounting base, a metal layer capable of brazing, e.g. Al layer, is formed on the rear surface of the semiconductor element. By so doing, not only cheaper brazing materials such as Al-Ge eutectic crystal alloy can be used, but also stable brazing can be achieved with high reliability. It is also possible to prevent that such a metal as having a large coefficient of diffusion into the semiconductor and causing a life time of minor carriers to be reduced, e.g. Au, tends to diffuse into the semiconductor.

Title: Tension control mechanism for timing belt
Inventor: NAKAYOSHI HIDEKI
IPC: F01L1/02
Filed: 1982-03-16
Abstract: PURPOSE:To automatically control the tension of a timing belt depending on the ambient temperature, by providing a wax-type thermosensitive unit to displace a timing pulley on the timing belt in response to the temperature sensed by the unit. CONSTITUTION:When the ambient temperature has risen, wax 36 expands so that a rod 32 is moved leftward as to the drawing, against a spring 38. At that time, a swing member 22 for a timing pulley 20 is turned counterclockwise about a pin 21 to displace a cylindrical member 25 leftward. Consequently, the tension of a timing belt 26 which would be made excessive due to the expansion between a cam shaft and a crankshaft is controlled to a desired level. When the ambient temperature has fallen, the wax 36 contracts so that the swing member 22 and the cylindrical member 25 are turned clockwise about the pin 21. Consequently, the tension of the timing belt 26 which would be made too small is controlled to the desired level.

Filed: 1985-03-06
Abstract: PURPOSE:To provide a paper feeder mechanism which does not impose a heavy load on an electric motor but gives an operator the feeling of a click sound and allows a detent gear to be fixed by providing an arm which damps the pressure of a detent spring and strongly presses the detent spring to a detent gear through the forward and backward movement of the spring integrally with a platen knob. CONSTITUTION:A knob 6 is thrusted in to allow a detent gear 4 to disengaged with a bevel gear 5 and introduce a condition where fine paper feed is performed. At that time, a detent spring does not have a strong pressing and fixing power on the detent gear 4 resulting in the generation of less load on an electric motor 2. If a platen knob 6 is pressed against the platen 1 side, an arm 8 advances, strongly pressing the detent spring 7 against the detent gear 4. Thus the detent gear 4 is pressed and fixed so that the platen 1 may freely rotate through the platen knob 6 to allow an arbitrary selected minute amount of paper feed to be performed. In this case, a ring 8a slips in its rotation.

Title: Detecting device for misalignment of optical fiber
Inventor: IDE TAKASHI
IPC: G02B6/24
Filed: 1988-02-25
Abstract: PURPOSE:To raise the detection accuracy of a misalignment, and also, to improve the work efficiency by inserting an optical means between an objective lens of an image pickup means for detecting the misalignment of an optical fiber and an image pickup element and varying the optical path length. CONSTITUTION:At the time of observing all cores of a multicore optical fiber 5, a first prism 12 is placed in a position which is separated from on an optical axis. At this time of observing each fiber, the first prism 12 moves onto the optical axis. In this case, since the optical path length becomes long, magnification becomes large by adjusting a distance between an objective lens 6 and the multicore optical fiber 5. By using the prism in such a way, a distortion of an image and an aberration are eliminated from a refraction of the lens. Therefore, a misalignment state of the optical fiber can be detected with high accuracy. Also, since an image whose magnification is different can be obtained easily, the work efficiency is improved.
