IPC: G02B6/122
Filed: 1995-01-10
Abstract: PURPOSE: To provide a simple method to produce a polyimide optical wavelength plate having a high conversion degree for polarized waves and high accuracy. CONSTITUTION: The film thickness of a polyimide film having anisotropy of refractive index in the film plane is controlled with high accuracy by etching. As for etching, it is preferable to shape a film to specified thickness by reactive ion etching using oxygen so as to obtain a polyimide film having desired retardation value. Or it is effective to use a UV asher, oxygen asher, or liquid phase shaping using hydrazine and potassium hydroxide soln. or sodium hydroxide soln. This method contributes to a high-performance waveguide type optical device into which the wavelength plate is assembled.

Abstract: PURPOSE:To form a channel section easily, to prevent the channel section from being damaged by plasma, and to match a drain film to a gate electrode accurately. CONSTITUTION:A gate electrode 12 is patterned on a glass substrate 10 and an SiN film 11 and an a-Si film 13 are deposited in sequence and then photoresist 14 is applied. From the rear side of the substrate 10, ultraviolet rays 15 are cast. After development and dry etching, a conductive section 13A is formed only on a gate Cr electrode 12. Then, plasma peeling of the photoresist is conducted and the photoresist is peeled evenly from the edge of the conductive section 13A and then a photoresist section 14B is formed. An n<+>-a-Si film and a drain Cr film are patterned by lift-off. After that, the photoresist 14B is removed by peeling. As shown in Figure (e), a channel section 19 is formed with high accuracy by going through the peeling process of the photoresist and thereby a thin-film transistor can be formed.

Title: Pressure controlling method in injection molding machine
Inventor: MIYAHARA MASAAKI
IPC: B29C45/50
Filed: 1990-01-26
Abstract: PURPOSE:To uniform the quality of a molded form and to prevent molding failure from occurring by retreating a screw to the position wherein pressurizing force of the screw for a pressure sensor is regulated to zero and thereafter detecting the pressure after finishing a weighing stage or an injection stage and correcting the controlled value on the basis of this detected pressure value. CONSTITUTION:A screw 2 is retreated after finishing a weighing stage or an injection stage and thereby firstly pressure reduction is performed until the pressure reaches the preset value Ps close to zero which is previously set. On the other hand, the screw 2 is retreated and moved only by the preset distance value Ls from a point of time when pressure reaches the preset pressure value Ps. As a result, pressurizing action of the screw 2 for a pressure sensor 3 is released and thereby back pressure and effect of rotation of the screw 2 are not imparted to the pressure sensor 3. Accordingly when pressure detection is performed after the screw 2 reaches the preset distance value Ls, the pressure value Pc to be detected becomes only the error component free from the pressure component such as residual pressure. Therefore when the controlled value related to the pressure control is corrected on the basis of this pressure value Pc, accurate correction can be performed.

Filed: 1985-01-31
Abstract: PURPOSE:To convert continuously a character group to a superior or inferior character by a simple operation, by converting automatically a superior or inferior conversion object character from the continuously inputted character group by using a conversion table. CONSTITUTION:The character group which is inputted continuously from a keyboard 1 is set to a KANA (Japanese syllabary) 11 at first. Subsequently, when the input is ended and a superior key is depressed, whether each character from the head of the KANA buffer 11 is the superior conversion character of a superior conversion table 4 or not is checked. As a result, in case of the conversion object character, it is converted to the corresponding superior character.

Subsequently, when the conversion is ended, the contents of the buffer 11 is written in a cursor pointer part on a sentence buffer 6, and a display corresponding to it is executed on a CRT2. The conversion is executed automatically in such a way, therefore, the character group can be converted continuously to a superior or inferior character by a simple operation.

Filed: 1986-01-30
Abstract: PURPOSE:To prevent punch through between a source and drain, to obtain an arbitrary avalanche breakdown voltage and to provide a low ON-resistance vertical MOS transistor, by uniformly flowing a breakdown current through the bottom part of a second-conductivity type diffused layer when a high reverse voltage such as a surge voltage is applied. CONSTITUTION:A drain region has a conventional three-layer structure. A P-type diffused layer 5 is formed in an N<-> type low concentration layer 4. The bottom part T of the layer 5 reaches an N-type medium concentration layer 3. The acceptor impurity concentration of the layer can be variously adjusted in a range, which is higher than the impurity concentration of a P-type well region 6. Then, the region 6, which has the acceptor impurity concentration determined by the desired threshold voltage value of a vertical MOS transistor, is formed in the layers 5 and 4. An N<+> type source region 7, which has donor impurity concentration, is formed in the layer 5 and the region 6. Then a gate oxide film 8 is formed at a part on each of the layers 4 and 5 and the regions 6 and 7. A gate electrode layer 9 and an interlayer insulating film 10 are sequentially formed thereon. A source electrode 11 is formed on the entire surface. The withstanding voltage of the P-N junction at each place in such a vertical MOS transistor becomes the minimum at the bottom part T of the layer 5. Breakdown starts at this part, and its current flows uniformly through the bottom part T.
