Patent JP-H01151330-A (JP)
Title: Sub signal transmission system
Inventor: FUJIMURA HIROSHI
IPC: H04J3/06
Filed: 1987-12-08
Abstract: PURPOSE:To prevent transmission speed from being increased by modulating the polarity of a frame synchronizing bit included in a main signal corresponding to the polarity of a sub signal at a transmission side, and reproducing the sub signal simultaneously with taking frame synchronization by utilizing the frame synchronizing bit whose polarity is modulated at a reception side. CONSTITUTION:For example, five bits of frame synchronizing pulse are arranged distributively in one frame of the main signal, and the polarity of the frame synchronizing pulse is changed corresponding to that of the sub signal. In other words, the polarity of the frame synchronizing bit '1' in the first and second frames of the main signal is set as the polarity of '0' of the sub signal corresponding to the position of a third frame. Thereby, at the reception side, the frame synchronization is taken by detecting five bits of frame synchronizing pulse of '1' or '0', and simultaneously, the sub signal is reproduced by detecting the change of the polarity of them. In such a way, it is possible to prevent the transmission speed of the main signal from being increased.

Title: Picture coder
Inventor: OTAKA HIDEKI
IPC: H04N19/146
Filed: 1989-12-01
Abstract: PURPOSE:To attain coding with less generation of distortion by coding an HH signal so as to calculate a code length, deciding the code length assigned to an LL signal based on the result and applying coding to the LL signal so as not to exceed the assigned code length. CONSTITUTION:After an HH signal is quantized by a quantizer 107, the result is coded by a variable length coder 211, the code length is calculated by a code length calculation device 214 and a code length assignment device 215 decides the code length assigned to the LL signal based on the result of calculation. Since the sum of the code lengths of the LL, HH signals is set to a prescribed value in advance, the code length assigned to the LL signal is fluctuated proportional to the fluctuation of the code length of the HH signal. As to the LL signal whose code length is assigned, a DCT arithmetic unit 205 applies two-dimension DCT and selects the quantization method in the quantizer 206 so as not to exceed the assigned code length and a variable length coder 210 applies coding. The quantization method in the quantizers 208, 209 is selected to the LH, HL signals so that the predetermined code lengths are not exceeded and the variable length coders 212, 213 apply the coding.

Title: Soundproof cover
Inventor: NARITA MASAHIRO
IPC: B29C45/16
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a soundproof cover excellent in a sound insulating effect. SOLUTION: A soundproof cover, comprising a vessel-shaped main unit part covering a sound source and a flange-shaped fixed part forming a peripheral edge partly of this main unit part, comprises an outer side member 3, comprising an outer side main unit part 31 and an outer side fixed part 32 formed of bard resin forming an outer side part of this main unit part and the fixed part, and an inner side member 4 comprising an inner side main unit part 41 provided by spacing a cavity 31a from the outer side main unit part 31 formed of soft resin or rubber softer than hard resin forming art inner side part and an inner side fixed part 42 integrally fixed to the outer side fixed part 32.

Abstract: PURPOSE:To make it possible to set a torque in a high-speed response and with high precision by connecting a dynameter for suction directly to a DC motor, by providing an engine characteristic simulator and by correcting torque-current conversion data by learning. CONSTITUTION:A dynamometer 3 for suction is connected directly to a DC motor 2 and an engine characteristic simulator 21 having torque instruction data being flat for the number of revolutions is provided. The meter 3 is controlled by a current instruction value I* obtained by conversion of a torque instruction T* of the simulator 21 by a torque-current converting part 11. Measured values of a current I and a torque T of the motor 2 corresponding to the instruction value T* of the simulator 21 are determined for each throttle opening instruction theta and each number N of revolutions. Based on deviations of these measured values from the instruction value T*, a current correction value is determined and this is added to the instruction value I*, so as to determine a fresh current instruction value. The current of the motor 2 is controlled by this fresh instruction value and further updating of the instruction value I* is repeated by repeating the above-stated computation. According to this constitution, the precision in measurement of the torque can be increased considerably.

Title: Oxide superconducting member having excellent joining property
Inventor: ITO KEIICHIRO
IPC: H01Q9/16
Filed: 1990-11-19
Abstract: PURPOSE:To improve the joining property of the oxide superconducting member by uniformly incorporating a metal at the content density higher than the content density in the parts exclusive of a joint part in the part of this member to be joined to another member, and specifically changing the content density of the metal in the boundary part. CONSTITUTION:The metal 3b (e.g.; silver) is incorporated nearly uniformly at the content density higher than the content density in the parts exclusive of the joint part into the part of the oxide superconducting member 3a to be joined to the other member 11a. Further, the content density of the metal 3b to be incorporated into the boundary between the joint part and the part exclusive of the joint part is changed at a changing degree below the extent at which a change of impedance does not arise. The oxide superconducting member 3a having the excellent joining property is thus produced. A method of embedding the fine pulverous metal 3b into the part to form the joint part of a green sheet at the time of molding of the green sheet in the process for producing the oxide superconducting member 3a is adequate as a method of incorporating the metal 3b into the oxide superconducting member.

Filed: 1994-12-15
Abstract: PURPOSE: To improve the coverage of an insulation film on an overlying interconnection in a multilayer interconnection structure by a method wherein the etching selection ratio to the interconnection pattern is relatively small on a surface layer side of the insulation film as compared with on a deep layer side and a portion along etching of the interconnection pattern is tapered. CONSTITUTION: A first interlayer insulation film 11 resides between a gate electrode 6p and a second layer W-polyside film 15p. A lower layer side of this first interlayer insulation film 11 is an SiO2 film 9 having a stoichiometrical composition and an upper layer side is a PSG film 10. However, the etching selection ratio to the second layer W-polysilicide film of the PSG film 10 is about 15 and not high as compared with the etching selection ratio (about 20) of the SiO2 film 9. Thus, when the second layer W-polyside film 15 is over- etched, the part is etched to reduce a film thickness, and further a tapered part 10t occurs in an edge part of a bit contact lead-out pad electrode 15p.
