Title: Coating with fluorescent substance
Inventor: IMAMURA HIROSHI
IPC: H01J9/22
Filed: 1980-04-30
Abstract: PURPOSE: To eliminate the unevenness of a coating layer which might be caused by the generation of air bubbles, by dipping the lower end of a glass bulb into an aqueous suspension of a fluorescent substance, and reducing a pressure inside the glass bulb to suck up the suspension and to apply the suspension onto the inside surface of the glass bulb.  
     CONSTITUTION: A decompression pump connected to a suction opening 5 is communicated to a glass bulb 1, by the operation of the cock 11 of an electromagnetic valve 6, so that a pressure inside the bulb 1 attached to an air-tight chuck 3 is reduced, and that an aqueous suspension 9 of a fluorescent substance in a tank 8 penetrates upwards into the bulb 1. At this time, air bubbles 12 are floating on the surface of the suspension 9, so that they do not penetrate into the bulb 1. When the suspension 9 further rises and reaches a level switch 7, the cock 11 of the valve 6 is rotated and communicated to the atmospheric pressure side by the detecting operation of the level switch 7. Consequently, air is introduced through an opening 4, and the level of the suspension 9 descends under its own weight. Thus, the film 13 of the fluorescent substance is formed on the inside surface of the bulb 1.

Filed: 1987-03-13
Abstract: PURPOSE:To easily compare and observe a difference in almost the same position of two image data, by displaying partially two pieces of different data on the same screen by putting a cursor line as a boundary, and moving the cursor line to a notice part. CONSTITUTION:In case of comparing and observing image data A, B obtained by bringing the same object to be photographed to image pickup at the same angle by an infrared-ray image pickup art 1, a cursor line is brought to position designation in each image data by a cursor position designating circuit 5. In this case, each image data is divided into areas of A1/A2 and B1/B2 by the cursor line, and based on a position signal of the cursor line in this case, a cursor/address converter 6 reads out an address signal for reading out an image data of each area from image memories 4a, 4b, to send out control circuit 7. The circuit 7 reads out a partial image data A1 and B2 and stores them in a display memory 8. Subsequently, a read-out synthesizing circuit 9 superposes and displays a stored image of the memory 8 and the contents of a cursor display memory 11. In such a way, a difference in almost the same position can be easily compared and observed.

Abstract: PROBLEM TO BE SOLVED: To obtain a route guidance apparatus by which a route according to the characteristic of a driver can be selected by a method wherein a driving difficulty which is judged on the basis of living-body measured data on a driver in a driving operation and on the bass of a road condition is compared with a predetermined allowable driving difficulty and an optimum route is decided. SOLUTION: A driving load level in every running section judged on the basis of living-body measured data in a running operating and a by-individual driving load level computed on the basis of the number of running operations in a specific section are registered in a by-individual driving load database 20. Then, a shortest running route is found by an optimum-route search method, and a driving difficulty on the route is computed by a driving-difficulty judgment means 24 is every predetermined section on the basis of data from a by-road- condition database 14 and on the basis of by-individual driving load data which is registered in a database 20. When the computed driving difficulty does not exceed an allowable driving difficulty, for every driver, which is input in advance, a running-route decision means 28 decides an optimum route.  When the driving difficulty exceeds the allowable driving difficulty, the shortest route is searched again, and the above opeartion is repeated.

IPC: H01S5/00
Filed: 1985-03-22
Abstract: PURPOSE:To reduce the junction capacitance and to enhance the response speed by using the semiconductor layers on both sides of an active layer as the injection and attraction layers of carriers. CONSTITUTION:A P-type active layer 12 and a P-type clad layer 13 are arranged on a semi-insulating substrate 11 to form a stripe mesa structure. On both sides of them, N-type semiconductor layers 14 and 15 having a wider forbidden band width than the active layer 12 are arranged. The layer 14 is constituted as the injection supply layer of carriers into the active layer 12 and the layer 15 is constituted as the layer attracting the carriers produced in the active layer 14 due to a 'trail effect'. Accordingly a P-N junction area is substantially small, compared with a conventional element constitution so that the junction capacitance can be reduced.

Abstract: PURPOSE:To remove dissolved manganese along with a suspended substance by an extremely compact water purifying device in small-scaled water purifying equipment by filtering dissolved manganese-containing raw water into which chlorine is injected by a micro-filter membrane or ultrafilter membrane having a manganese dioxide crystal deposited on the surface thereof. CONSTITUTION:In a membrane filter apparatus for tap water wherein micro- filter membranes or ultrafilter membranes having a manganese dioxide crystal deposited on the surfaces thereof are connected in series, raw water is allowed to flow in a raw water receiving tank 2 from a raw water pipe 1 and sodium hypochlorite 4 in a tank 3 is injected into the raw water receiving tank 2 by a pump 5. Next, the raw water containing sodium hypochlorite in the raw water receiving tank 2 is supplied to the manganese dioxide-deposited permeation membrane 7 by a raw water pump 6 to perfectly remove a suspended substance and manganese in raw water. Since the permeation membrane 7 becomes a clogged state when this state is continued, it is periodically backward washed.

Abstract: PURPOSE: To change discharging quantity of a pump by two steps according to a pressure change by engaging a main plunger with a subplunger through a lock ball as well as inserting a lock pin, to release said engagement, slidably into the main plunger.  
     CONSTITUTION: A main plunger 9 and a subplunger 4 are engaged with each other by a lock ball 15. A lock pin 12 provided with a lock groove 14, is inserted into the main plunger 9 by pushing it in one direction with a spring 13. In case of a light load, the main plunger 9 and the subplunger 4 operate in a single united body, while in case of a heavy load, the lock pin 12 operates to the right and the lock ball 15 drops into the lock groove 14 releasing the engagement of the main plunger 9 with the subplunger 4. Since only the main plunger 9 operates after said release of the engagement, the discharging quantity can be charged by two steps in response to a pressure change.
