Title: Optical switch
Inventor: NOJIMA SHUNJI
IPC: G02F1/313
Filed: 1989-02-27
Abstract: PURPOSE:To reduce the absorption loss of rectilinear propagation light when no voltage is applied by setting forbidden band width and well width so that the value of the performance exponent of a semiconductor multiple quantum well is close to the maximum value including its maximum value. CONSTITUTION:When no voltage is applied between electrodes 15 and 16, the light which is made incident from a port P1 propagates rectilinearly in an active area 12-5 as it is and is guided in a passive area 12-2 to reach a port P2. When a voltage is applied, the light reaches a port 3. In this case, when the performance exponent of the semiconductor multiple quantum well is prescribed by the forbidden band width and well width of the semiconductor multiple quantum well, the forbidden band width and the well width are so set that the value of the performance exponent is close to the maximum value including its maximum value, thereby eliminating the joint interface between the passive area and active areas. Consequently, the absorption loss of the rectilinear propagation light when no voltage is applied is reduced.

Title: Method of attaching diamond material
Inventor: ROBAATO SHII KEIN
IPC: C23C16/27
Filed: 1993-02-12
Abstract: PURPOSE: To selectively form a diamond film by providing the inside of a reflection furnace with an electron emitting tip and carbon-contg. molecular reactive gases and dissociating hydrocarbon by the electrons released from this tip.  
     CONSTITUTION: A supporting substrate 401 has the electron emitting tip 402 which is disposed on its surface and is coupled operatively thereto. An extraction electrode 440 is disposed apart from the supporting substrate 401 and a region is defined therebetween. An external voltage source 410 is operatively coupled between the extraction electrode 440 and the supporting 401. Reactive gases exist in this region. The electrons released into this region impart energy to the carbon-contg. molecular components of the reactive gases to ionize the carbon-contg. molecules to positive. The carbon-contg. ions made radical are accelerated toward the negative electron emitting tip 402 and are deposited there. The etching components of the reactive gases preferentially react with the non-diamond molding of the material to be deposited, by which the layer/ films of the diamond material 406 are preferentially/selectively deposited on the releasing front end 402.

Title: Indirectly heated type cathode structure
Inventor: DOI KENICHI
IPC: H01J1/20
Filed: 1982-03-24
Abstract: PURPOSE:To stick a cylinder body fast to a cap body as well as to prevent any spatters by welding from occurring and deformation at the time of welding, by press-fitting the cap body covering an opening into a bulging part formed up in close vicinity to the opening end at one side of the cylinder body, while welding both parts together at this press-fitted part. CONSTITUTION:A circular bulging part 4b is formed up in close vicinity to an opening end 4a at one side of a thin cylinder body 4 made of a nickel-chromium alloy, and the side part of a thick cap body 5 made of a metal containing nickel as the main constituent is press-fitted in the peripheral surface of this bulging part 4b. However, this press-fitting is of inteference fit in type, so that no clearance is produced in the press-fitting part at all and therefore the side wall part of the cap body 5 coheres fast to one end edge of the cylinder body 4. And, since both these parts are deposited by means of a spot welding or regular welding process at this close adhesion part, possible spatters caused by the clearance are nil and furthermore the occurence of deformation at the time of welding comes almost to nothing.
