Title: Output buffer circuit
Inventor: TAKAHASHI YASUSHI
IPC: H03K19/0175
Filed: 1992-02-26
Abstract: PURPOSE:To reduce a noise radio wave generated by an output buffer incorporated in a logic IC used in radio equipment. CONSTITUTION:An input signal is supplied to an integration circuit and an output buffer transistor. A comparator 6 compares the integration circuit output 7 and buffer output voltage and when buffer output voltage responds ealier than the output of the integration circuit, the output transistor is turned off to make buffer output voltage always follow the output voltage of the integration circuit. Thus, the changing speed of output voltage is decided with the time constant of the integration circuit irrespective of the size of load capacity and at the time of small load capacity, the rapid change of output voltage is not generated so that the noise radio wave generated along with the rapid change of output voltage is reduced.

Filed: 1987-03-27
Abstract: PURPOSE:To attain sharp synchronizing separation without jitter by providing a peak hold section holding the bottom voltage of a synchronizing pulse and detecting a DC level of an input signal and a differential amplifier section amplifying the difference between the output voltage of the peak hold section and the bottom voltage of the synchronizing pulse.

Title: Diffraction grating array and display device using same
Inventor: TAKAHASHI SUSUMU
IPC: G02F1/1335
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain such a display device that noise due to unnecessary light is not viewed and decreases in the saturation and contrast of a display pattern are not recognized by shielding an area where not diffraction grating is present between cells consisting of diffraction gratings from light. SOLUTION: Illumination light made incident on a mask array (liquid crystal panel) has its transmitted light intensity modulated by mask cells (liquid crystal cell) and is made incident on a diffraction grating array. Even if some of the light is made incident on a nonoperation area, it is not transmitted to an observer side and the light beam transmissivity of the nonoperation area is decreased. Namely, a light shield means which does not make the illumination light incident on areas other than a selected cell is provided on the top surface of the diffraction grating array.  For example, the light shield means is formed by forming a positive photosensitive adhesive layer over the entire surface of the diffraction grating array, exposing the part corresponding to the arrangement of diffraction grating cells, and coloring an unexposed part which is still adhesive by toner scattering or transfer.

Title: Frame atomic absorption spectrophotometer
Inventor: KOJIMA SEIJI
IPC: G01N21/31
Filed: 1995-03-31
Abstract: PURPOSE: To vary the aperture ratio of an optical system depending on the alteration of a burner by inserting a mask into the optical path of a condensation optical system or retracting the mask therefrom depending on the kind of frame gas. CONSTITUTION: The luminous flux X from a holocathode lamp H passes through a plane mirror 3, a troidal mirror 4, a burner (frame 5) and a troidal mirror 6 and enters into a spectrometer 7 where the absorption spectrum at the frame 5 is measured by means of a photomultiplier P. A mask 10 having an opening M is inserted into the luminous flux X by means of a pulse motor 11, for example. Since the mask 10 is entered into the luminous flux X and retracted therefrom in front of the spectrometer 7, effective solid angle of the light beam is decreased when the mask 10 enters into the optical path X resulting in an optical system having a large aperture ratio.  On the contrary, when the mask 10 retracts from the optical path X, an optical system having a small aperture ratio is realized thus ensuring a substantially constant absorption sensitivity regardless of the slot length of a burner 5 being used.

Title: Superwide-angle zoom lens
Inventor: SUDA SHIGEYUKI
IPC: G02B13/18
Filed: 1981-05-20
Abstract: PURPOSE: To obtain a small-sized superwide-angle zoom lens which has the reduced barrel-shape distortion aberration at the wide-angle edge, by setting the specific numerical conditions to a combination of a lens group having a negative focal distance and a lens group having a positive focal distance and using an aspherical surface.  
     CONSTITUTION: The first lens groupIhaving a negative focal distance includes a convex meniscus lens L 1 , a biconvex lens L 2 , a biconvex lens having high refractive power at the image field side and a convex lens L 4  having high refractive power at the image side. The air spave between the groupIand the 2nd lens group II having a positive focal distance is varied to change the focal distance of the entire system. The absolute value of the curvature radius R 4  at the image filed side of the lens L 2  is larger than that of the curvature radius R 5  of the subject field side of the lens L 3 . At the same time, the lens L 1  has an aspherical surface. The specific conditions relating to the power distribution and the aspheric surface are set to this lens system. As a result, a small size is realized and at the same time the distortion aberration is suppressed. Thus a lens system is obtained with 1.5 zoom ratio and F3.5 with a 93° picture angle at the wide-angle edge for instance.
