Title: Light source device
Inventor: UMEGAKI SHINSUKE
IPC: G02B27/42
Filed: 1988-12-05
Abstract: PURPOSE:To guide a secondary higher harmonic as a light beam which can easily be converged and to realize small-sized constitution which is easily handled and adjusted by converting the output of a secondary high-frequency generating element where laser light is incident into a parallel light beam by a collimator lens which has a necessary annular diffraction grating pattern. CONSTITUTION:The laser parallel light beam generated by a laser light source 1 and spherical lenses 2 and 3 is passed through an incident light fiber type secondary high-frequency generating element 4 to output a secondary higher harmonic. The secondary higher harmonic is converted into parallel light of specific order separated excellently from light of other order by the collimator lens with the annular grating pattern formed so as to form part of each of flanks of conic bodies which have concentric slanting surfaces of diffraction gratings and share a center axis 52, so that the converted light is projected. This secondary higher harmonic is converted by the collimator lens with the interference pattern into the light beam which is easily converged and the light is guided out to obtain the small-sized light source device which is easily handled and adjusted.

Abstract: PURPOSE:To record/reproduce a still picture with high picture quality by recording one of chrominance signals PB and PR in the order of fields when recording the still picture, and interpolating a thinned line with up and down lines in the same frame when reproducing the still picture. CONSTITUTION:In a still picture mode, a movable contact piece (a) of changeover switches 12B and 12R is contacted to a fixed contact C in the first field of the signals PB and PR, and only the 1H delayed signal PB is supplied to the fixed contact C of a changeover switch 20. In the next second field, the movable contact piece (a) of the switches 12B and 12R is contacted to a fixed contact piece (b), and only the 1H delayed signal PR is supplied to the fixed contact C of the switch 20. As the result, only the signal PB is recorded in the first field, and only the signal PR is recorded in the second field. In a reproducing route, the thinned line is interpolated with the up and down lines in the same frame, and the picture is reproduced, Thus the high-fidelity image can be reproduced without lowering the vertical resolution of the chrominance signal.

Title: Gas pressure gauge
Inventor: MARUNO NAOHIKO
IPC: G01L9/00
Filed: 1987-12-04
Abstract: PURPOSE:To enhance measuring accuracy, by employing circuit constitution based on a specific formula to exclude the effect of the variation component of inherent impedance. CONSTITUTION:Circuit constitution satisfying a condition of predetermined formula (wherein Vc is the amplitude of pulse voltage, Vo is constant voltage, k is an adjustable coefficient and Ic is a resonance current) is employed. An analogue switch 11 switches the DC constant voltage from an adder circuit 4 corresponding to the output signal of a polarity discrimination circuit 12 not only to obtain predetermined voltage Vc but also to apply the same to a quartz vibrator 2. A phase shifting circuit 13 is connected to the circuit 12 and discriminates the polarity of the AC signal V2 supplied from the circuit 13 to apply the same to the switch 11. A current/voltage converter circuit 14 for converting the current Ic flowing to the vibrator 2 voltage is connected to the output side of the vibrator 2. The vibrator 2 receives the voltage Vc from the switch 11 to permit a current Ic to flow. By this method, the apparent inherent impedance of the vibrator 2 can be made constant without being affected by the vibration component.

Abstract: PURPOSE:To provide a lens initial position detection device which can precisely detect the initial position of a lens movably set in a lens barrel and which use a Hall element in an inner focusing system zoom lens device or the like. CONSTITUTION:The Hall element 22 and a magnet 20 are housed in a casing 17. The magnet 20 is fixed to a lever 16 in the casing 17.

Title: Method for correcting defect of photomask
Inventor: KOIZUMI YASUHIRO
IPC: G03F1/74
Filed: 1991-11-26
Abstract: PURPOSE:To prevent the transfer of the fine chipping generated in a phase shifter as a defect to a wafer by embedding a light shielding material into the chipping part of the phase shifter. CONSTITUTION:The photomask 1 for phase shift is a reticule formed with the original pictures of integrated circuit patterns of a size of, for example, 5 times the life size for the purpose of transferring the prescribed integrated circuit patterns to the semiconductor wafer and is constituted of a glass substrate 2, light shielding patterns 3a to 3e formed in the prescribed regions on the main surface thereof and the phase shifters 4a, 4b formed respectively between the light shielding patterns 3a and 3b as well as the light shielding patterns 3c and 3d. The light shielding material 6 is embedded in the chipping part 5 of the phase shifter 4b to prevent the transmission of light at this time. As a result, the quantity of the transmitted light merely decreases in the chipping part 5 and the phase thereof is the same as the phase of the light transmitted through the phase shifter 4b around this part. Since the stressing of the contrast is thereby prevented, the transfer of the chipping part 5 as the defect to the wafer is obviated.

Title: Manufacture of cathode-ray tube
Inventor: HAYASHI YASUHIKO
IPC: H01J9/39
Filed: 1994-12-15
Abstract: PURPOSE: To provide a cathode-ray tube of high in-tube vacuum and excellent quality by ionizing the inert gas in the tube by means of the thermoion emitted from a cathode, and irreversibly adsorbing the ionized gas by a focusing elec trode. CONSTITUTION: The residual gas in a tube is ionized to the positive electrode by the thermoion emitted from a cathode 2, and the ionized gas is adsorbed by a focusing lens 5 for generating the main lens kept at the negative potential. The inert gas such as Ar which is the main composition of the in-tube residual gas is reduced in volume during the manufacturing process of a cathode ray tube. Because a final acceleration electrode 6 during this treatment is kept at the voltage higher than that of the focusing electrode 5, the ionized inert gas is adsorbed mainly by the focusing electrode 5, and little adsorbed by the final acceleration electrode, a shadow mask, a magnetic shield and a fluorescent screen, etc. Thus, the final acceleration electrode 6, etc., is kept at the high positive voltage in the normal operation of the tube, and no gas is emitted even when the electron beam hits.
