Inventor: TAKAHASHI SATOSHI
IPC: G02B6/38
Filed: 1989-01-12
Abstract: PURPOSE:To facilitate the alignment of the optical axis of optical fibers by engaging the reference projecting lines or reference grooves of an aligning jig with the guide grooves or guide projecting lines formed on a par of the fiber arrays, and respectively separately pressing the fiber arrays to the aligning jig, thereby aligning the fiber arrays to each other. CONSTITUTION:The reference projecting lines 7a or reference grooves of the aligning jig 7 are engaged with the guide grooves 3 or guide projecting lines formed on a pair of the fiber arrays 2 and a pair of the fiber arrays 2 are pressed respectively separately to the aligning jig 7 to align a pair of the fiber arrays 2 to each other, by which the optical axes of the fibers 1 are aligned. A pair of the fiber arrays 2, therefore, align eventually based on the reference projecting lines 7a or the reference grooves of the aligning jig 7. Even if the fiber arrays 2 and array blocks 5 are fixed in the state twisted against each other, the easy alignment of the fiber arrays 2 to each other is possible and the optical axes of the optical fibers 1 are easily and rapidly aligned.

Title: Semiconductor memory device
Inventor: OGISHIMA JUNJI
IPC: H01L21/8242
Filed: 1985-01-18
Abstract: PURPOSE:To improve the withstand voltage feature of an insulating film by a method wherein an insulating film positioned between a pore-type capacitor and a word line is so designed as not to have an interface, in the direction of the film thickness, that may cause leak currents between the pore-type capacitor and the word line. CONSTITUTION:A polycrystalline silicon layer 10 is formed to cover the entire surface of a semiconductor substrate 1 to be developed into an insulating film to insulate a pore-type capacitor from a word line WL. Next, from a region planned for a MISFET, an conductive layer 7, silicon oxide film 8, and the polycrystalline silicon layer 10 are removed. A process follows wherein an insulating film 11 is formed by oxidizing the polycrystalline silicon layer 10 to provide insulation between the word line WL and pore-type capacitor. The polycrystalline silicon layer 10 is not positioned on the sides of the conductive layer 7 but, because the conductive layer 7 itself is made of polycrystalline silicon, the sides of the conductive layer 7 is also covered by the insulating film 11 after oxidation. The insulating film 11 is equipped with an excellent withstand voltage capability because it has no interface in the direction of the thickness of its film.

Abstract: PURPOSE:To obtain a fluoroscopic picture having always fixed contrast by converting the intensity of a signal so that the appearance-frequency of signals of the same signal-intensity comes to be equal over all the signal-intensity to expand the brightness ranges of a high-brightness part and a low-brightness part. CONSTITUTION:The video signal of the fluoroscopic picture is transferred to a lookup table 6 as its address specifying signal through an A/D converter 1 and a selector 2'. Thus the signal is converted to different signal intensity that corresponds to an original signal-intensity, and inputted to a cathode-ray tube via a D/A converter (a). Also the video signal is transferred to a histogram memory 3 via a selector 2, and is made the address specifying data for the memory 3. Accordingly, the histogram of the video signals is formed in the memory 3. The output of the memory 3 is transmitted to an arithmetic unit 5, where data of the appearance-frequency related to the intensity of the video signal is operated. And the result is made the data of the lookup table 6. The content of the table 6 is updated at every one field, to display an animation picture by the X-ray fluoroscopy.

Title: Liquid crystal display body
Inventor: IWAMATSU SEIICHI
IPC: G02F1/1339
Filed: 1989-01-12
Abstract: PURPOSE:To prolong the display life of a liq. crystal display body by sealing a molecular sieve in the display body. CONSTITUTION:Wiring 2 of an ITO (indium tin oxide) film and a polyimide orienting film 3 are formed on the surface of each of glass substrates 1, a liq. crystal 5 is held between the two substrates 1 with a gapping agent 4 and the substrates 1 are sealed with epoxy resin 6.

Abstract: PURPOSE:To improve the responsiveness to the temperature of an electro-magnetic clutch and as well as enable to quickly measure the temperature of the clutch by a method wherein the measurement of voltage across an exciting coil driving under constant-current system is performed. CONSTITUTION:When the exciting voltage of an exciting coil L1 reaches to the standard current by operating an accelerator pedal, the voltage, which is proportional to the voltage across the exciting coil L1 generating under the condition that the exciting current equals to the standard voltage, is outputted from a subtracting circuit 8. If said outputted voltage exceeds set voltage V2, the output of a comparator 9 goes to high level. In this case, the set voltage V2 is determined in advance to be the value corresponding to the voltage drop generated in the case that the temperature of the exciting coil L1 has the set temperature. Accordingly, when the temperature of the exciting coil L1 exceeds the set temperature, the output of the comparator 9 goes to high level, resulting in setting the output of a flip-flop FF to high level and sounding an alarm buzzer.
