Title: Horizontal synchronizing pll circuit
Inventor: WAKAI YOICHI
IPC: H03L7/08
Filed: 1987-03-04
Abstract: PURPOSE:To improve the stability of a horizontal synchronizing PLL circuit using a gate circuit type phase comparator by detecting a code from a frequency divider in the PLL circuit for a prescribed period before and after a low frequency signal period such as a vertical synchronizing signal or the like so as to generate a pseudo horizontal synchronizing signal thereby compensating a composite synchronizing signal. CONSTITUTION:The pseudo horizontal synchronizing signal generator 105 detects a code from a frequency divider 102 to generate a pseudo horizontal synchronizing signal. A signal selector 108 selects a pseudo horizontal synchronizing signal E when the level of an output signal G of a (T1+T2) detector 109 is at logical 1 and selects a composite synchronizing separator signal F when the signal G is at logical 0. The output signal B is inputted to a phase comparator 103 and subjected to phase comparison with a frequency division signal A. Thus, the rate of levels 0, 1 in the output of a phase comparator 103 is made stable even during the low frequency signal period such as a vertical synchronizing signal and then the output D of the low pass filter 104 is stable. Then the disturbance of the picture is decreased.

Title: Prism optical system and optical information processor using said system
Inventor: NAKAO TAKESHI
IPC: G11B7/135
Filed: 1985-03-13
Abstract: PURPOSE:To obtain a prism optical system whose geometrical property will not change with respect to a wavelength change by employing two prisms made of materials having different wavelength variances of a refraction factor at a certain interval as a prism composing the prism optical system. CONSTITUTION:A laser beam emitting from a semiconductor laser 100 is made into a parallel flux by a lens 101, converted into a flux having the width less than the effective aperture of an A/O modulator 103 by means of the 1st prism system 102 and is made incident on said modulator 103. The prism system 102 has such a feature that the flux emitting from the prism will not develop an angle change due to the wavelength change of the laser beam. The light beam emitting from the A/O modulator 103 is shaped into a circular flux by the 2nd prism system 104, and stopped down a disk 106 by a stop-down lens 105. In terms of the emitting angle change coming out of the prism, which is caused by the wavelength change of the laser beam, a change in a slopped- down spot position is effectively suppressed. Moreover, since the incident and emitting light beams are parallel, the constitution and adjustment of an optical head can be comparatively easy.

Title: Co/o2-system fuel cell
Inventor: ISHIDA TETSUYOSHI
IPC: H01M8/06
Filed: 1985-03-13
Abstract: PURPOSE:To prevent CO from being discharged outside a fuel cell system by using a device for separating CO2 in a liquid electrolyte exhausted from a fuel cell and a device for absorbing a carbonyl complex of CO. CONSTITUTION:CO 33 is introduced into a CO absorber 32 and absorbed by a complexing agent in the CO absorber 32 to produce a CO-complex solution 34 which is then introduced into a fuel chamber 30. In a fuel electrode 27 in the chamber 30, the solution 34 reacts with water to produce CO2, H<+>, electrons and the complexing agent. The thus produced H<+> and electrons migrate into an air electrode 28 through a diaphragm 29 and a load 35 and react with oxygen 36 in the air electrode 28 to produce water 37. On the other hand, a gas-liquid mixture 38 composed of CO2 and the complexing agent is introduced into the separator 31. The mixture 38 introduced into the separator 31 is separated into CO2 39 which is then exhausted from the top of the separator 31 and a complexing agent 40 which is then supplied into the CO absorber 32 through the bottom of the separator 31. The complexing agent 40 reabsorbs CO 33 in the absorber 32 to produce a solution 34. By thus efficiently separating CO2 from the gas-liquid mixture 38 exhausted from the chamber 30, CO can be effectively utilized without being discharged outside the system.

IPC: H01L27/146
Filed: 1985-03-13
Abstract: PURPOSE:To relax the flapping phenomenon of spectral sensitivity characteristics due to the multiple interference of beams in a desired wave range by changing the film thickness of a surface layer in a single element. CONSTITUTION:A protective film 1, a central section thereof has a stepped section, is formed onto the surface of an impurity diffusion region 2 detecting beams. Spectral sensitivity characteristics generally flap at a period of lambda<2>/2nph in the vicinity of a wavelength of specific lambda when np represents the refractive index of the protective film and (h) the thickness of the protective film. Accordingly, the stepped section is shaped at the central section and the protective films having two different thickness are formed, thus acquiring smooth spectral sensitivity characteristics, in which flapping is offset, in a desired wave range.

Title: Thick-film type thermal recording head
Inventor: SATOU KAZUYASU
IPC: H01L49/02
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a thermal recording head meeting the enhancement of the smoothness of a head surface as well as a longer life, by a method wherein a protective layer includes a crystallized glass layer facing a heating resistor layer and an amorphous glass layer formed on the surface outside the crystallized glass layer. CONSTITUTION:In a thick-film type thermal recording head composed by laminating a heat-resistant layer 2, an electrodes 3 and a heating resistor layer 4, and a protective film 7, successively on an insulating substrate, such as an alumina substrate 1, the protective film 7 is composed of a plurality of layers. The protective film 7 is so constructed as to be composed of a crystallized glass layer 5 facing the heating resistor layer 4 and an amorphous glass layer 6 formed on the surface outside the crystallized glass layer 5. The upper layer 6 of the protective film made of an amorphous glass is superior in surface smoothness, which enables a smooth feed of a medium such as transfer paper. In addition, since a crystallized glass superior in wear resistance is used for the lower layer 5, the wear, crack, damage, and others can be prevented by the lower layer from extending downwards even if such troubles occur in the upper layer, thus never affecting the heating resistors.
