IPC: H04N7/01
Filed: 1982-09-09
Abstract: PURPOSE:To form a video signal for one frame's share of other standard systems, by reading out two lines' share of video signals for one field's share according to a standard system and adding the video signals of two lines' share with a prescribed coefficient respectively for weighting. CONSTITUTION:A composite color video signal for one field's share of the NTSC system picked up and recorded with an electronic still camera 1 is formed. Further, only the field not subject to average interpolation is extracted at a converter 5 from a signal from an auxiliary circuit 34 and a frequency division circuit 37, and a digital signal after A/D-conversion is applied to a memory 44 corresponding to a video signal for one field's share of the NTSC system. Then, the memory 44 is read out sequentially and applied to memories 48, 49 corresponding to the video signal for one line's share and two optionally adjacent line video signals are stored. Further, the signal is read out and multiplied with a prescribed coefficient and the outpt of multiplication is added. Thus, the video signal for one frame's share of the CCIR system is formed from the video signal for one field's share of the NTSC system.

IPC: H01L23/52
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To form an additional wiring to connect to a wiring at the lower part of an insulating film so as to enable IC debugging, correction, failure analysis, etc., by forming the additional wiring film by irradiating an IC element with focused beam and relatively scanning the IC element and the focused beam. SOLUTION: An insulating film is processed by applying ion beam only on a region to be connected. Then, a gate valve 25 is opened and an LSI chip is transferred to a position on a placing table 24. The LSI chip is moved to a laser beam irradiation position by an X-Y table, and a wiring correcting region is aligned. Then, a shutter 30a is opened, laser beam is applied on the wiring correcting region, and the shutter 30a is closed after a fixed time. The organic metal gas near the laser applied region is decomposed by the laser irradiation, a metal thin film is deposited and the wiring is corrected. Thus, the exposed part of the wiring is prevented from being contaminated or oxidized when taken out to the atmosphere, and a wiring can be formed by laser CVD.

Title: Microstrip antenna
Inventor: SUZUKI YASUO
IPC: H01Q21/06
Filed: 1981-10-05
Abstract: PURPOSE:To suppress an unnecessary higher order mode, by providing feeding points of adjacent antennas to location deviating from the center of each antenna in opposite direction. CONSTITUTION:To feeding points P111 and P112 and P121 and P122 which are provided to microstrip antennas 11 and 12, respectively, in such a way that one  point is moved by 90 deg. to the center O on each antenna, signals having phase relationships of 0 deg., 90 deg., 90 deg., and 180 deg. are supplied from an electric power distributor 20. Radio waves of circular polarized ones are generated from each microstrip  antenna 11 and 12. The distributions of the lowest order mode surface electric  currents of the circular polarized waves are the same in phase at both antennas  and, therefore, they strengthen with each other. On the contrary, the circular  polarized waves due to the distributions of the secondary higher order mode surface electric current at both antennas become opposite in phase and, therefore,  they deny with each other.

Title: Diffusing feed type electron beam source
Inventor: HONDA YUKIO
IPC: H04N1/14
Filed: 1982-09-13
Abstract: PURPOSE:To perform easily the electron radiation with angle limit without introducing oxygen gas, etc. from outside, by using an oxide of titanium, hafnium, niobium, magnesium or cerium or a solid solution or a fused mixture of above- mentioned elements and their oxides to a feed source. CONSTITUTION:First, a tungsten wire of 0.1-0.15mm. diameter is spot-welded at the tip of a V-shaped tungsten (W) heat generator 1 having 0.1-0.15 diameter. The tip of the generator 1 is shapened by electrolytic polishing to obtain an electron radiator 2. Then a titanium oxide (TiO2, etc.) or the mixture powder of titanium (Ti) and TiO2 is attached to a connecting part of the generator 1 to the radiator 2 or around the generator 1 to obtain a quasi-feed source 4'. Then the generator 1 is energized and heated under vacuum or in an Ar gas atmosphere, etc. Thus the source 4' is fused instantly to obtain a feed source 4. The same effect can be obtained if a mere fused mixture of titanium and titanium oxide is used to the source 4.

Title: Narrow groove automatic welding method of pipeline girth joints
Inventor: SAKURAI HIDEO
IPC: B23K9/167
Filed: 1978-12-21
Abstract: PURPOSE: To control welding heat input, reduce the hardness of girth weld zones and prevent the induction of cracking, etc. by letting a non-consumable electrode follow the consumable electrode for gas metal arc welding given with weaving in the high speed down welding of the captioned joints.  
     CONSTITUTION: High-speed down welding is done with a gas metal arc while a consumable electrode 1 as a preceding electrode of the girth joint welding of a pipe 3 is being weaved in order to improve the penetration and bead shape. Welding heat input is added by as much as the heat quantity of the arc by one or more non-consumable electrode 2 as the succeeding arc heat source. The weld beads 5 by the electrode 1 tend to become convex beads. These are made to flat beads 6 by weaving, and the occurrence of the lack of fusion 7 in the groove corners is prevented by the second path. The electrode 2 further slightly melts the upper part of the beads 5 to smooth the surface and the accumulation of layers free from defects is accomplished by the second path and at the same time the cooling rate of the weld zone is decreased.

Title: Camera used both for silver salt photography and electronic image pickup
Inventor: MARUYAMA ATSUSHI
IPC: G03B17/48
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent a user from erroneously confirming a photographic range even though parallax is caused between a silver salt photographing device and an electronic image pickup device without incurring the drastic rise of cost by inhibiting picture display on the monitor means of the electronic image pickup device by a control means when a macrophotography mode is selected. SOLUTION: The macrophotography mode is a mode set in the case of photographing a subject coming close to a camera, and a difference is made between the angle of view by a 1st photographing optical system 51 and the subject and the angle of view by a 2nd photographing optical system 52 and the subject. If the photographic range of a latent image exposed on silver salt film in the macrophotography mode is confirmed by using the picture of the subject displayed on an LCD monitor 34, it is mistaken. Therefore, a CPU 29 sets a picture non-display state by stopping the supply of an image signal from a signal processing circuit 33 to the monitor 34 or switching driving bias for the monitor 34 so that the image formed on an image pickup element 17 and produced by an area sensor driving circuit 32 and a signal processing circuit 33 may not be displayed on the monitor 34.
