Title: Reflection type liquid crystal display device
Inventor: IMAYOSHI KOJI
IPC: G02F1/1335
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a reflection type liquid crystal display device permitting a bright screen display with a wide viewing angle by making a light reflection film a light scattering reflection film constituted by laminating a light scatterer consisting a light reflective thin film and microlenses, and a flattened film. SOLUTION: A light reflection film 12 is constituted of a metal reflection film 13 (light reflective thin film) and plural 1.5 μm thick micro lenses 14 arranged on the metal reflection film positionally matched therewith and a flattening film 18 for coating these plural microlenses 14 and flattening their surfaces. Therefore, a beam of light made incident from an observer's side substrate 11b is uniformly scattered by a light scatterer consisting of the micro lenses 14 and also reflected by the metal reflection film 13 (light reflective thin film), and is made to exit from the observer' side substrate 11b. Consequently, the external light is converged at the position of the observer, and it becomes possible to display a bright picture irrespective of an incident angle of the incident light.

Title: Analogue-digital converter
Inventor: MUNEDA TETSUHIRO
IPC: H03M1/36
Filed: 1980-10-21
Abstract: PURPOSE:To obtain an A-D converting device of a short conversion time, by using A-D converters with sampling times shifted from each other in parallel. CONSTITUTION:A positive voltage is always applied to a terminal 4, and a reference voltage is generated at equal intervals by a resistance 11 when a proper power source voltage is applied to terminals 1 and 3. When the voltage of a terminal 2 is equal to the reference voltage, voltages of output terminals 6 and 7 of an amplifier A are equal to each other and are a voltage 15. When the signal of the voltage 17 is applied to a terminal 5 under this state, the output voltage of an amplifier B are shown as voltages 8 and 9, and sampling pulses of a voltage 18 are generated. Next, when an observation signal is applied to the terminal 2, the voltage of the terminal 10 becomes a voltage 10 by a diode 10. This pulse voltage and the reference voltage of a terminal 16 are compared with each other by an amplifier C, and the comparison result is subjected to code conversion by an encoder 17. Consequently, if  another A-D converter with the sampling time shifted is used in parallel, the con version time is shortened.

Abstract: PURPOSE: To make possible recording and reproducing to and from arbitrary positions of a magnetic tape by comparing the positioning signal and set signal being read from the magnetic tape and controlling the recording and reproducing start positions of the tape.  
     CONSTITUTION: The operation instruction information 101 from an operator control panel 1 causes a magnetic recorder-reproducer 9 to start by way of a reproduction operation control circuit 5 and running control circfit 16. As a result, the reproduction signal of the positioning information from a magnetic tape is stored in a register 4 via circuit 5 and the storage content thereof and the position set signal having been set with the operator control panel 1 and having been stored in a register 2 are compared in a comparator 3. When the coincidence signal which the circuit 3 outputs through this comparison is applied to the circuits 5, 16, the magnetic tape of  the apparatus 9 stops. Hence, the recording and reproducing to and from the desired position of the magnetic tape may be performed without destroying the information having been accommodated by way of an interface 6.

Abstract: PURPOSE:To perform accurate braking operation even when the reflection factor and modulation degree of a disk vary by constituting an RF signal detecting circuit which constitutes a braking circuit so that the divided voltage of a DC voltage obtained by rectifying an RF signal is compared with a signal obtained by detecting the envelope of the RF signal. CONSTITUTION:The RF signal detecting circuit 1 obtains a detection signal (b) and a 1/2 divided voltage (b') from the RF signal (a) and a comparator 1a generates a position waveform (c) indicating that a main spot is on a track.
