Title: Dot matrix displaying device
Inventor: HISAOKA AKIJI
IPC: G02F1/136
Filed: 1988-03-07
Abstract: PURPOSE:To discriminate the difference in and variation of driving capacities of transistors by making the discriminating reference level of tests optionally changeable and performing the tests by using plural kinds of the reference levels. CONSTITUTION:A discriminating circuit 4 is constituted by connecting the source of a load transistor Tr1 which is a p-channel FET and the drain of a drive transistor Trd which is also a p-channel FET, and a reference voltage Vs is applied across the gate of the load transistor Tr1. The output voltage which is applied when a dot matrix display device is tested is applied across the gate of the drive transistor Trd. The driving capacity and variation of the capacity of a displaying body driving transistor Tr2 which drives picture elements are discriminated by comparing the output level of the transistor Tr2 with various reference levels set in changeable states at the discriminating circuit 4. Therefore, the displaying quality of this dot matrix displaying device can be tested.

Title: Radar apparatus
Inventor: NISHIKAWA HITOSHI
IPC: G01S13/66
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent tracking of a wrong target from occurring by adding a function of controlling switching-over of a signal transmission route when a search/track switch device carries out searching and tracking. SOLUTION: When a level change detector 23 judges that a shift to a tacking (that it is a true target) is possible, the level change detector 23 controls a search/track switch device 7 to shift to the tracking mode in accordance with a mode switch signal (i) to form a tracking signal route. When the detector judges that a shift to a tracking mode is impossible (that it is a clutter), the level change detector 23 controls the search/track switch device 7 and a search/ catch switch device 10 to continue a search mode in accordance with the mode switch signal (i) to form a search signal route. Since the level change detector 23 for controlling the search/track switch device 7 and search/catch switch device 10 is installed, a wrong target can be prevented from being caught and tracked.

IPC: B22D43/00
Filed: 1987-03-09
Abstract: PURPOSE:To efficiently and surely suck and remove suspended dross, by making the pressure in a vacuum chamber lower than that in a snout, sucking the suspended dross of the inside of the snout by the pressure difference, and providing a means for actuating a check valve when suction is finished. CONSTITUTION:Dross 28 is floated up to the melt surface in the snout 11 in the galvanization of a steel sheet, etc. A valve stem 23 is pulled up to close the exhaust port 22 of the vacuum chamber 18, and the pressure in the vacuum chamber 18 is made lower than that in the snout 11 by the suction of an ejector 26.

The ball 20 of a valve is pushed up by the sucked suspended dross 28, and the dross is stored in the vacuum chamber 18. After a specified time, the valve stem 23 is pushed down to open the exhaust port 22, and the suspended dross 28 in the vacuum chamber 18 is discharged into a shrouding frame 27. At this time, since an injection port 19 is closed by the ball 20, the back flow of the suspended dross into the snout 11 is prevented.

Title: Transmission type projecting screen
Inventor: SEKIGUCHI HIROSHI
IPC: G03B21/625
Filed: 1991-02-26
Abstract: PURPOSE:To obtain a thickness with sufficient strength, to extend a light absorbing part which prevents external light reflection, and to improve the diffusion characteristic by providing the light absorbing part between the vertical and horizontal lenticular lenses. CONSTITUTION:A light adsorbing layer 12 is formed in a part where light in the vicinity of the converging point of the vertical diffusion lenticular lens 11 does not pass, in the transmission type projecting screen. When light is converged by the vertical diffusion lenticular lens 11, parts where band-like light is converged and parts where light is not transmitted are present horizontally and alternately on the plane parallel to the vertical diffusion lenticular lens 11, in the vicinity of the part where the light is converged. Accordingly, the light adsorbing layer 12 is formed on the part where light is not transmitted. Therefore, since the light adsorbing layer 12 does not adsorb video-light projected from a light source but adsorbs external light from the observation side, the external light interference in video and the deterioration in contrast are prevented. Also, even when the pitch of the lenticular lens 11 is small, the thickness of the screen can be increased.

Title: Manufacture of sm-co magnet
Inventor: YAMADA HIROYUKI
IPC: H01F1/08
Filed: 1985-03-20
Abstract: PURPOSE:To enable to cut down the cost of production of the titled magnet by a method wherein Sm2O3 powder and Co powder are placed in a retort together with the Ca of specific grain diameter, and they are reduced by heating under the specific conditions. CONSTITUTION:Sm2O3 powder is used for the Sm which is a component of the Sm-Co magnet, Co powder is used for the Co of the magnet, and Ca grains of 0.5-10mm in diameter are used as the reducing agent of the Sm2O3. If the grain diameter of Ca is less than 0.5mm, the rate at which the Ca is formed into CaO before placing it into the retort is increased, and if the grain diameter of the Ca exceeds 10mm, the reaction efficiency is lowered. The Sm2O3 powder, the Co powder and the Ca grains of the prescribed quantity are mixed, placed into the retort, and reduced by heating. At this time, inside the retort is heated up to 1,000 deg.C or above in an Ar atmosphere. The period of processing of the fine Ca grains is to be made longer when the temperature is less than 1,000 deg.C. After the reducing process is finished, the powder is washed with water and dried up as occasion demands, and the CaO is removed. As low-priced Sm2O3 is used and the reducing efficiency is improved using the Ca grains of specific grain diameter, the magnet can be manufactured at low cost.
