Title: Manufacture of liquid crystal element
Inventor: UENO KOTARO
IPC: G02F1/1337
Filed: 1989-09-19
Abstract: PURPOSE:To prevent the generation of the uneveness of display by short- circuiting electrically an electrode on the upper glass substrate and an electrode on the lower glass substrate. CONSTITUTION:Clips 12 between the upper and the lower electrode terminals 3, 3' and 4, 4' of a liquid crystal element are short-circuited electrically. In this case, as for polyimide oriented films 5, 6 on the upper and the lower electrodes 3, 4, since its mechanical strength is week, the clip and the electrode can be short-circuited enough electrically by a saw tooth alligator clip whose pinching force is strong, but it is desirable that the polyimide oriented film of a clip connecting part is eliminated with a razor, etc., in advance. In this case, since the potentials between the upper and the lower substrates 1, 2 of a liquid crystal element in a high frequency voltage are equal, no discharge is generated between the upper and the lower substrates 1, 2. In such a manner, deterioration of the liquid crystal orientation caused by discharge can be prevented, and a uniform and satisfactory display can be secured.

Title: Color picture tube
Inventor: INOUE TOSHIAKI
IPC: H01J29/07
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To accurately measure even if measuring positions are slightly varied, when displaying an image band along the long sides of the upper and lower ends of an image plane and inspecting the upper and lower pin cushion distortions and horizontal trapezoidal distortions of the image plane, by slanting the long side in the vicinity of a diagonal part of an effective surface of a shadow mask along the bow-like arrangement of electron beam passing holes. SOLUTION: Preferably in this color picture tube, at least 10 mm of the long side in the vicinity of a diagonal part of an effective surface is slanted. Since the vertical deviation of the electron beam 16 entering the effective area of a phosphor screen 2 is small, distortions can be measured accurately in the vicinity of the short axis end of the image plane by being hardly affected by a step 4, even if the position of a CCD camera are varied slightly.  Since the long side in the vicinity of the diagonal part of the effective surface of the shadow mask is slanted along the bow-like arrangement of electron beam passing holes 16 in the vicinity of the diagonal part of the long side, the measurement accuracy of the distortions is not varied, even if they are measured at one end side of the step 4 or at the other end side thereof, so that they can be measured accurately in the vicinity of the diagonal part of the long side of the image plane.

Title: Packet communication system
Inventor: KAWABE KOICHI
IPC: H04L12/70
Filed: 1993-09-29
Abstract: PURPOSE:To obtain a packet communication system capable of improving transmission efficiency while maintaining information quality by controlling an entropy encoding part by a code word replacing part and adjusting a generated code length. CONSTITUTION:When it is judged that digital signals encoded in the entropy encoding part 103 at once are too long to be housed in the packet of a fixed length, a fixed length control part 104 controls the encoding part 103 by the code word replacing part 105 and turns the generated code to the length which can be housed in the packet of the fixed length. In this case, some of the code words whose code word length is long allocated to an event whose occuring possibility is low are replaced with the code words whose code word length is shorter allocated to the different event for turning noise between the original event to be less than a fixed value and the code length is adjusted. Thus, the noise does not become large for the event whose occuring possibility is high and information signals are encoded without giving an increasing trend to quantization errors and are efficiently housed inside the packet.

IPC: H04H40/36
Filed: 1993-09-29
Abstract: PURPOSE:To improve the S/N of sound signals at the time of AM stereo reception by providing a circuit for reducing a low frequency component. CONSTITUTION:The high-pass filters (low-cut filters) 21 and 22 of 18dB/oct are constituted of a transistor Q1 (Q2), capacitors C1, C5 and C3 (C2, C6 and C4) and resistors R3, R6 and R8 (R4, R7 and R9.) At the time of receiving AM stereo broadcasting, output signals from the output terminals 12 and 13 of an AM stereo demodulation circuit 10 are passed through the high-pass filter provided with high attenuation characteristics serving also as the buffer amplifier of a switching circuit 11. Thus, by attenuating unnecessary noise and setting the cut-off frequency of the high-pass filter to a frequency for attaining improved tone quality, unnecessary pilot signals and a low-band noise component are efficiently removed and reception with the improved tone quality is made possible at the time of receiving the AM stereo broadcasting.

Title: Speaker collation system
Inventor: NISHIMURA SHINGO
IPC: G06F3/16
Filed: 1990-09-12
Abstract: PURPOSE:To form the borders of 'registered persons' and obtain a high matching rate in a short period of time by not extracting the learnt pattern of an unregistered person from an actual speech, but setting candidate points in the multidimensional space based on an analytic result by using a random number deciding the range of candidate points at the time of speaker matching using an input voice. CONSTITUTION:A main component analysis part analyzes main components of learnt patterns of the registered persons which are stored in a learnt pattern storage part to obtain a conversion matrix. Then a random number generation part sets candidate points for the learnt pattern of the unregistered person in the multidimensional space by using the random number. A distance calculation part and a pattern selection part selects whether or not the distances between the candidate point K of the unregistered person and categories A - D of the respective registered persons are within a certain range. Further, a reverse conversion part calculates the product of data on the unregistered person and the reverse matrix of one conversion matrix to obtain the learnt pattern of the unregistered person. This result is stored as the learnt pattern of the unregistered person in the learnt pattern storage part. Consequently, the effective borders of 'registered persons' are generated effectively without preparing the speech of the unregistered person and the high matching rate is obtained in a short period.

Abstract: PURPOSE: To ensure restraint of reflection in an image receiving tube and or like in a room and a decrease of light loss caused by a louver by controlling outgoing light of a luminaire which incorporates a strait tube type lamp and is provided with a reflection board and the louver. CONSTITUTION: Light emitted from a strait tube type fluorescent lamp 11 which is installed in a lamp socket at inner surfaces of both ends of a main body 10 goes out through a louver 16. The light from a reflection board 13 among the light made incident to each cell 17 of the louver 16 comes incident to an opening surface 20 almost orthogonally and the other reflection light goes out at a glare cutting angle by way of an establishment of a relation of α>=β>0 between a focus (f) of a paraboloid of the reflection board 13 and a diameter of a lamp and an upper end surface part of the louver 16, and therefore it is possible not to occur a reflection onto an image receiving tube and to make a thickness of an upper end part of the cell 17 of the louver 16 thin to thereby decrease light loss and improve an apparatus efficiency.
