Title: Production of color liquid crystal display device
Inventor: SHIMADA SHINJI
IPC: G02F1/1368
Filed: 1988-05-11
Abstract: PURPOSE:To eliminate the need for the photomask to be exclusively used for forming a light shielding film by coating a light shielding resin from above the photoresist remaining on picture element electrodes after patterning and removing the photoresist on the picture element electrodes and the light shielding film by a lift off method. CONSTITUTION:A black or dark color resin 4 is coated by using a spinner, etc., on a substrate while the exposed photoresist 3 remains on patterned transparent conductive films 2. Further, the resin 4 is cured by heating. The remaining photoresist 3 and the resin 4 on the photoresist 3 are stripped by the lift off method if the substrate coated with the resin 4 is ultrasonically cleaned in a solvent such as acetone. The need for the photomask to be exclusively used for patterning of the light shielding film is thereby eliminated. In addition, the display contrast is improved.

IPC: H01L29/80
Filed: 1987-05-12
Abstract: PURPOSE:To enable an output to be controlled by feeble magnetic field signals while enabling a wide gap between two conductive channels to be made by a method wherein current injecting electrodes are composed superconductor. CONSTITUTION:A current flowing in a control wire 23 controls another current flowing between two superconducting electrodes 21a, 21b just like a conventional switching element by the size of a magnetic field induced in a region encircled by conductive channels 3, 5 and the superconducting electrodes 21a, 21b. Coherent injection of electrons into two constantly conductive GaAs quantum well channels are performed using the superconducting electrodes 21a, 21b regardless of the gap (d) between the two conductive channels 3, 5. A switching element with performance capable of switching by feeble magnetic field signals can be produced since the two conductive channels can make a wide gap. Furthermore, the GaAs conductive channels can be produced by MBE growing process capable of controlling single atomic layer so that the junction in excellent reproducibility with high accuracy may be capacitated.

Title: Chain float hoisting device of metal plate scale removing solution tank
Inventor: HOTANI SETSUO
IPC: C23G3/02
Filed: 1978-09-19
Abstract: PURPOSE: To hoist floats up to the inside of the cover the let lifting of metal plates be accomplished smoothly and rapidly by connecting the floats to the winding ropes of a winch by way of auxiliary media.  
     CONSTITUTION: A number of supporting rods 5 are placed along the surface of chain floats being floated in a solution tank 1 at a fixed spacing across the entire length of the floats 4 and said supporting rods 5 are mounted to the protrusions 6 on the top surface of the single bodies of the floats 4. The winding ropes 7 of a winch 3 installed on top of a cover 2 are connected to these supporting rods 5. When the ropes 7 are wound up the winch 3, the supporting rods 5 and floats 4 are hoisted up and therefore waveform bending of the floats 4 is obviated, hence abrasion owing to the contact of the single bodies with each other, whereby durability is given to the floats 4. Since the metal plate 11 is independently lifted after the floats 4 have been lifted, drying out the solution becomes fast and damages of plate surfaces, etc. are prevented.

Title: Function generator with address direct designating memory
Inventor: SAKAMOTO SHOICHI
IPC: G06F1/02
Filed: 1986-05-19
Abstract: PURPOSE:To extremely simplify the constitution of a function generating device together with a big reduction of cost, by using the digital value received from an A/D converter as it is as an address designating signal of a memory. CONSTITUTION:The output digital value serving as a function corresponding to the digital value supplied from an A/D converter 1 is previously stored in a memory area where said input digital value is an address. The analog input signal is converted into the digital value by the converter 1. This digital value is supplied directly to an address bus line 6 of a memory 3 and used as the data to designate an address of a memory area in the memory 3. Then the data stored in the designated address is taken out of the memory 3 as the output digital value and outputted to a D/A converter 4 to be converted into the analog output signal for output. In such a way, a desired function is produced with no use of a microprocessor and therefore the constitution a function generating device is extremely simplified together with a big reduction of cost.

Title: Optical recording and reproducing device
Inventor: OKAMURA SHIROU
IPC: G11B11/10
Filed: 1982-07-05
Abstract: PURPOSE:To perform reproduction with a high S/N ratio, by extending the space for interaction between a laser beam and magnetic recording to rotate a plane of polarization sufficiently. CONSTITUTION:A beam 31 which a laser 30 generates becomes linearly polarized light by a polarizing plate 19 and is flowed along a magnetic recording track 3 and is inputted to a photoelectric converter 21 through an approximately orthogonal polarizing plate 18. Since the plane of polarization is rotated by magnetic recording, a reproduced output is obtained from the converter 21. Since the rotation angle of the plane of polarization due to this Faraday effect is proportional to the length of the optical path where the magnetic field is changed, the rotation face is enlarged to improve the S/N ratio when a long recording track is used.

Filed: 1984-06-08
Abstract: PURPOSE:To restrain a speed change shock and to quickly step on an engine brake by closing a by-pass oil path and a discharge oil path by means of a control valve in D-range and opening the above oil paths in a shift range from D- range to a low speed range. CONSTITUTION:In case of D (drive) range, as the control pressure at a control port 40 is zero, a spool 38 is pressed to the control port 40 by a spring 42 to close a by-pass oil path 26 and a discharge oil path 28. Accordingly, oil is conducted to a low clutch 10 only through an oil path 14, and oil is discharged to a high clutch 12 only through an oil path, so that a speed change shock at the time of kick-down and power-on is restrained and a speed change time is lengthened. On the other hand, in case of a shift range from D-range to a low speed range, the by-pass oil path 26 and a discharge oil path 28 are opened. Thus, speed change is quickly accomplished, and an engine brake can be stepped on immediately.
