Abstract: PURPOSE: To extend band width by using a resistive signal power divider and a resistive signal power coupler. CONSTITUTION: The resistive signal amplitude or power divider 16 receives a signal from an input port 12 and divides the signal into two equal amplitude parts and a phase shifter 28 of an upper channel 50 supplies a phase-shifted and attenuated signal to an amplifier 36.

Title: Optical disk reproducing device
Inventor: UEHARA MINORU
IPC: G11B7/085
Filed: 1994-12-15
Abstract: PURPOSE: To provide an optical disk reproducing device capable of suppressing the occurrence of a read error by limiting the number of tracks traversed in a once jump according to the occurrence rate of the read error. CONSTITUTION: Information read by an optical head 103 is demodulated to a digital signal by a demodulater 105 after being amplified by an RF amplifier. Although the read error occurs when a scratch or dust is stuck on an optical disk 101, the read error is detected and corrected by an ECC 111. The occurrence frequency (or error rate) of the read error is measured by an error frequency measurement circuit 121, and the occurrence of the state becoming tracking impossibility is prevented by the fact that the more reducing the number of upper limit jumps decided by a jump control circuit 123 the more the occurrence frequency of the read error becomes large.

Filed: 1989-11-30
Abstract: PURPOSE:To lower the dependency of a contrast on visual fields and the degree of polarization of a display and to improve visibility by providing a diffuser in contact with outer side of an exit light side polarizer. CONSTITUTION:The diffuser 6 is provided in contact with the outer side of the exit light side polarizer 5 of the liquid crystal display element with transmission illumination disposed with the liquid crystal 3 of the optically rotatory power changing with light by a voltage between a pair of the polarizers 2 and 5. The transmission illumination light is projected through the polarizer 2, the liquid crystal 3 and the polarizer 5 to the diffuser 6. The diffuser 6 acts to scatter the polarized light from the exit side polarizer 5 to the light approximate nearly to natural light and to lessen the dependency on visual field angles by isotropic scattering. Thus, the dependency of the contrast on the visual field angles and the degree of polarization of the display are lowered and, therefore, the visibility is improved.

Title: Control device for internal combustion engine
Inventor: TAKAHASHI ATSUSHI
IPC: F02D43/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent poor combustion due to an intake air temperature. SOLUTION: When an intake air temperature in an engine 11 is lower, the temperature of a mixture filled in a combustion chamber 16 becomes lower, causing poor combustion due to too much amount of EGR during exhaust recirculation in such a state. An electronic control unit for the engine 11 calculates an intake air temperature correcting coefficient for reducing and correcting the amount of EGR in accordance with an intake air temperature or an intake air temperature correcting coefficient for increasing and correcting the amount of fuel to be injected. Correcting the amount of EGR or the amount of fuel to be injected in accordance with the correcting coefficient provides stable combustion at a lower intake air temperature.

Title: Apparatus for detecting back flow of waste solution of pneumatic splitter in lc-ms connection part
Inventor: SHOJI HIDEKAZU
IPC: G01N30/72
Filed: 1990-11-19
Abstract: PURPOSE:To prevent the damage of a pneumatic splitter by detecting the back flow of an excessive sample solution on the basis of the change of a detection signal detecting the flow of the excessive sample solution. CONSTITUTION:When a waste solution mixed with gas is discharged through a discharge pipe 4, bubbles are generated from the leading end of the discharge pipe 4 to rise. Now, when a back flow is generated, the amount of the waste solution flowing through the discharge pipe 4 is reduced or becomes zero and the amount of the gas mixed with the waste solution is also reduced or becomes zero and, therefore, the back flow can be detected by measuring the number of the bubbles generated from the leading end of the discharge pipe 4. Therefore, a light source 72 and a photodetector 73 are provided at the leading end position of the discharge pipe 4 in opposed relationship so as to hold a cell 71 therebetween and the light from the light source 72 is allowed to be incident to the photodetector 73. Since the quality of the light reaching the photodetector 73 from the light source 72 is changed when bubbles are generated from the leading end of the discharge pipe 4 to rise, the number of bubbles can be measured according to the change of the quantity of light.

IPC: C08L77/02
Filed: 1991-10-30
Abstract: PURPOSE:To provide a self-fusible winding wire, which allows only small deformation of a coil caused by the spring back of the winding soon after the formation of a deflection yoke coil. CONSTITUTION:Varnish, whose main component is copolymer polyamide, containing 55-70 percentage by weight of 12-nylon, 10-25 percentage by weight of isophorone diamine adipate, and 10-25 percentage by weight of other monomer being able to form polyamide, is applied directly or via other insulating material to a conductor so as to be baked. As the deformation of a deflection yoke coil by means of the spring back of a winding wire is small, it is possible to prevent a color deflection error caused by the convergence defect of a color television set.
