Title: Mass spectrograph
Inventor: NAITOU MOTOHIRO
IPC: H01J49/28
Filed: 1983-09-14
Abstract: PURPOSE:To increase the resolution of a mass spectrograph widely by forming an electric field in front of a field consisting of multiple fields and installing a slit either in the position of a middle convergence point located between said electric field and said field consisting of multiple fields or near the middle convergence point. CONSTITUTION:Ions passing through a middle slit 11 placed in the position on which ions are converged by a double divergence mass spectrometer 2, become incident upon a collision chamber 5 installed in the immediate back of the slit 11. Daughter ions produced in the collision chamber 5 then become incident upon an electric field produced between concentric cylindrical electrodes 12 and 12' installed in the back of the collision chamber 5 before being converged on the position of a second middle slit 13 by means of the above electric field. Ions passing through the slit 3 then become incident upon a multiple-field mass spectrometer 16 consisting of magnetic poles 14 and 14' for producing a magnetic field perpendicular to the surface of this paper and a pair of concentric cylindrical electrodes 15 and 15' for producing an electric field perpendicular to the above magnetic field. After that, ions passing through the mass spectrometer 16 become incident upon an ion detector 17 and detected by it. Owing to the above constitution, a very high resolution is achieved.

Abstract: PURPOSE:To prevent the choking of fuel discharge nozzles and a fuel inflow pipe by installing such a device as water jacket in a fuel discharge nozzle and around the parts which are communicated with said nozzles and hence cooling a fuel discharge section. CONSTITUTION:A number of fuel discharge nozzles 26 are installed in a circumferential direction inside a throat section 23 of a venturi pipe 20. A fuel inflow pipe 14 is connected with the fuel discharge nozzles 26. The throat section 23 is provided with a water jacket 27 installed in ring-shape, and connected with an inlet pipe 28 of cooling water and an outlet pipe 29. The throat section 23, the fuel discharge nozzles 26 and the tip of the fuel inflow pipe 14 connected with the aforesaid throat section and discharge nozzles are cooled by allowing cooling water to flow to the jacket 27.

Abstract: PURPOSE:To easily and faithfully reproduce plaster on which the trace of a foot is taken as a photographic image by using a process camera by radiating light so that the irradiation angles and the irradiation distances of two light sources facing to the plaster on which the trace of the foot is provided may be different and photographing the trace of the foot on a photographic sensitive material. CONSTITUTION:The light source A is set at an angle of about 30 deg. and at a distance of 80cm so that the trace of the foot on the plaster 3 may be irradiated with the light, and the light source B is set at an angle of about 50 deg. and at a distance of about 45cm so that an optical axis may be directly cast to the plaster 3, then irradiation is executed by both light sources A and B. When it is assumed that the light projected from the boxes of the light sources A and B is the parallel rays of light, relation between the light and the plaster 3 is shown by a broken line in figure, but actually much scattered light is included. By performing development after photographing, the silver image of the trace of the foot is faithfully and clearly reproduced on a positive material. The angle and the distance of the light sources A and B are different in accordance with the height of the plaster 3 and the height of the three-dimensional image of the trace of the foot, but they are comparatively easily found by performing a few tests.

A straight V shape is eventually formed. The exact working dimensions and shapes are obtd. in this way and the dispersion in the effect of suppressing a pseudo gap is decreased.

Title: Plain bearing for vibration isolation
Inventor: MASUDA KEIJI
IPC: E04H9/02
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a plain bearing for vibration isolation, which has excellent vibration-isolating performance while being able to be manufactured at a cost remarkably lower than the plain bearing for vibration isolation and in which height size can be inhibited in small size. SOLUTION: The plain bearing 10 for vibration isolation has a first assembly 16 combined with the lower structure 12 of a structure and a second assembly 18 united with upper structure 14, and the horizontal sliding surface 20 of the first assembly 16 and the horizontal sliding surface 22 of the second assembly 18 are slid and contacted. Vibration transmission from the lower structure 12 to the upper structure 14 is inhibited by elastic shear-deformation in the horizontal direction of a rubber sheet 4 interposed between the horizontal sliding surface 22 of the second assembly 18 and the upper structure 14 of the structure. The magnitude of the initial rigidity of the plain bearing 10 can be adjusted by properly determining the thickness of the rubber sheet 48. A partial contact between the sliding surfaces 20 and 22 is prevented by the elastic deformation of the rubber sheet 48.

Title: Resistor incorporated in semiconductor ic
Inventor: ATSUMI TSUGUKAZU
IPC: H01L21/822
Filed: 1983-09-16
Abstract: PURPOSE:To contrive to improve the integration degree by reduction of the occupation area of the resistor by contriving the reduction of pattern by a method wherein a resistance region of reverse conductivity type is arranged by bending in an island region of one conductivity type, and gaps between the resistance regions are gradually increased from the high potential side to the low potential side. CONSTITUTION:The island region 11 is formed by P-N isolation through isolation and diffusion after an N-epitaxial layer is grown on a P type semiconductor substrate. The resistance regions 12 are formed by selective diffusion of a P type impurity in the island 11 and then by bending at fixed pitches d1, d2, d3, and d4. For example, a 10kOMEGA resistor is formed in a semiconductor IC of a high withstand voltage at 50V. The resistance region 12 has a width of 15mum, length of about 1,000mum, and plane resistance Rs of 150OMEGA/square. The gaps between the regions 12 are gradually increased from the high potential side to the low potential side; where, d1 is 20mum, d2 25mum, d3 30mum, and d4 32.5mum respectively. Since the region 11 is biased at a power source voltage of 50V, the reverse bias voltage is ''0'' on the high potential side of 50V of the region 12, and a depletion layer is determined only by the diffused potential, coming to approx. 1mum.
