Title: Front surface cover and reflection mirror integrated electric discharge lamp
Inventor: NARITA MITSUO
IPC: H01J61/30
Filed: 1994-04-20
Abstract: PURPOSE:To restrict broken glass dispersion during lamp rupture and ensure safety by making the thickness of the glass of a front surface cover larger than that of a light emitting tube at a specific rate in an electric discharge lamp under the specific conditions. CONSTITUTION:In an electric discharge lamp arranged so that a single-ended electric discharge lamp is enveloped by a light transmitting front surface cover glass 7 and a reflection mirror 8, the lamp operating pressure is within 3X10<6>Pa, the inside volume of the lamp is set less than 1cm<3>, and an interval between a light source and the front surface cover glass 7 is within 20mm. In such an integrated electric discharge lamp, by forming the front surface cover glass 1.6 times as thick as the glass of a light emitting tube 1, the fragments of the lamp can be prevented from penetrating the front surface cover glass and dispersing even if the electric discharge lamp is broken. By using a crystal glass or reinforce glass for the front surface glass, the safety can be further enhanced.

Title: Straight line plotting processing system
Inventor: YOKOTA KEIICHI
IPC: G06T11/20
Filed: 1988-04-27
Abstract: PURPOSE:To execute a line plotting with a uniform line kind pattern by changing the magnification of the line kind pattern according to the plotting direction of a straight line at the time of the straight line plotting of a code/pattern conversion processing. CONSTITUTION:By a code/pattern converting part 2, when the straight line plotting is instructed from a control part 1, the line kind pattern is registered to a GDC (graphic display controller), and a direction theta of the straight line plotting is calculated. The pattern magnification is set by the calculated direction theta. Since a mean distance between picture elements is made 2<1/2> fold in 45 deg. direction and 1.25<1/2> fold in the direction of tan<-1>0.5 when it is 1 in 0 deg. direction, the pattern magnification is changed in being divided into three according to the plotting direction of the straight line. Thus, regardless of the plotting direction of the straight line, the straight line plotting by the uniform line kind pattern can be executed.

Title: Rectifier with p-n jounction part and its manufacture, and manufacture of semiconductor junction part
Inventor: EINTHOVEN WILLEM G
IPC: H01L29/861
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To form a diffusion part in a necessary recessed shape and making a high-resistance area which is formed as a result wider at a center part along its periphery by moving a heavily doped area to PN junction after a mesa is formed. SOLUTION: After a silicon dioxide layer 26 is grown, the heavily doped area 16 is moved toward a PN junction part deeply in the mesa by diffusion technology. In the geographic structure of the mesa, the diffusion part is generally recessed as the area penetrates the mesa. The distance between the peripheral edge 30 of the heavily doped area 16 and a wafer substrate 12 is larger than the distance between the center part 28 and wafer substrate 12. Therefore, a high-resistance N<-> area is wider along the side wall surface of the mesa than in the center part of the mesa, and consequently a higher yield voltage is developed on the surface of the rectifier.

Abstract: PURPOSE:To enable to surely remove the oil content in Rankine cycle by a method wherein medium vapor evaporated at a medium evaporator is led through a turbine bypass line to an LNG (liquefied natural gas) evaporator so as to liquefy the evaporated medium vapor and to temporarily store the resultant liquefied medium liquid therein in order to discharge the residual oil content in the medium evaporator. CONSTITUTION:When the oil content leaked in Rankine cycle is intended to be separated and removed, the medium liquid in a medium evaporator 4 is heated by sea water or the like under the condition that a liquid supply valve 5 is closed. The resultant evaporated medium vapor flows through a turbine bypass line 6 into an LNG evaporator 1 and is liquefied and recovered temporarily in the evaporator 1. The evaporator 1 is equipped with a liquid reservoir part, the capacity of which is enough large for the whole amount of medium liquid in the medium evaporator 4 to recover. After the continuance of said evaporation, the oil content and a very small amount of medium solved in the oil content are left behind and then discharged through an oil discharge line 7 outside the system of the cycle. Thus, the oil content leaked in Rankine cycle can surely be removed.
