Title: Lateral type insulated gate bipolar transistor
Inventor: SUMIDA HITOSHI
IPC: H01L29/786
Filed: 1994-03-24
Abstract: PURPOSE:To increase withstand voltage without thickening a bonding substrate on a support substrate, by increasing impurity concentration of a buffer region with the increase of expected withstand voltage. CONSTITUTION:In the case that the target withstand voltage of a lateral type IGBT is 250V, the drift length L is 30mum, the thickness of the N base layer 3 is 10mum, and the resistivity is 20OMEGAcm. When the surface impurity concentration of the N buffer layer 11 is set as 3X10<16>cm<-3>, 4X10<16>cm<-3> and 8X10<16>cm<-3>, element withstand voltage becomes higher in order. When simulation is performed on the basis of the above data, the withstand voltage increases as the surface impurity concentration of the N buffer layer 11 becomes higher. Since the target withstand voltage is 250V, the surface impurity concentration of the N buffer layer must be higher than or equal to 6X10<16>cm<-3>. In the same element structure, the element withstand voltage can be remarkably improved by increasing the surface impurity concentration of the N buffer layer 11.

Title: Dual luminous flux photoelectric photometer
Inventor: OOISHI KOUNOSUKE
IPC: G01J3/447
Filed: 1982-03-30
Abstract: PURPOSE:To reduce an error of measurement when two photoelectric detectors are used by providing a converging means on the path of each separated piece of polarized luminous flux, and allowing luminous flux with small sectional area to strike the photodetection surfaces of the photodetectors. CONSTITUTION:A light beam emitted from a light source 1 is converged by a lens 2 and transmitted through a sample 3. The transmitted light enters a spectroscope 5 through a projection slit 6, and a desired wavelength beam is selected and emitted from a projection slit 6. This monochromatic light enters a Wollaston polarizing prism 7 to be separated into a couple of polarized components, but a lens 8 is used for improving the separation efficiency of light with this light velocity to form an image of the projection slit 6 on the reflecting surface of a right-angled prism reflecting mirror 9. Further, lenses 18 and 19 are arragned between the reflecting mirror 9 and photoelectric detectors 10 and 11 and the image of the projection slit 6 formed by the lens 8 on the reflecting surface is formed on the photodetection surfaces of the photoelectric detectors 10 and 11. Thus, the luminous flux is reduced in area and detected on the high- sensitivity photodetection surfaces, so an error of measurement is reduced.

Title: Laser oscillator
Inventor: TANIO SHISEI
IPC: H01S3/092
Filed: 1993-03-12
Abstract: PURPOSE:To prevent the pumping light from a pumping lamp from reaching the sealing material on the outer periphery of the end portion of a rod for generating a laser light pulse thereby to provide a long life to the sealing material, by integrally forming a reflective film for reflecting the pumping light through the rod for generating a laser light pulse in a portion which is put in contact with the sealing material. CONSTITUTION:A reflective film 11 is integrally formed on a ground surface 10b of a rod 10 so as to cover this, by gold plating, gold evaporation, dielectric multilayered film or the like. The area where the reflective film 11 is formed is set so that it does not project beyond the distal end of a rod holder 4 and forms a portion in contact with a sealing material 9. Part of the pumping light travels from the rod 10 to the direction in which the sealing material is irradiated. However, since the reflective film 11 is interposed in its light path, the pumping light is fully reflected at the reflective film 11, thereby preventing the generation of a phenomenon that the pumping light reaches the sealing material 9. Since the reflective film 11 is formed on the ground surface 10b, the adhesion is good, whereby the reflectivity of the pumping light can be enhanced.

Title: Laser beam machining method
Inventor: SHINOHARA HISATO
IPC: H01S3/101
Filed: 1987-03-06
Abstract: PURPOSE:To improve the laser beam machining capacity and to reduce the machining cost by introducing laser light passed through a mask into an image- forming optical system and forming a groove in accordance with a mask pattern on the surface to be machined. CONSTITUTION:A mask 5 forming the desired pattern is arranged on an optical path of the laser light 4 such as excimer laser light, etc., with a wavelength having <=1,400nm and beam expanders 6 are provided in front of the mask 5 and the image-forming optical system 9 is arranged in the rear of the mask 5. The laser light 4 is expanded by the beam expanders 6 and a laser beam 7 is formed and made incident on the mask 5. The laser beam 8 passed through the mask 5 is projected on a work 10 via the image-forming optical system 9. Since the mask 5 is used to perform the laser beam machining with an optional desired shape, the machining capacity is improved and it is not necessary to enhance the working accuracy of the mask pattern, so the machining cost is reduced.

Title: Device for cutting with bandsawing machine while preventing vibration of band saw in its moving direction
Inventor: TOKIWA TOORU
IPC: B23D55/00
Filed: 1981-04-10
Abstract: PURPOSE:To avoid the occurrence of noises, by providing a unit at an interlocking section both for a driving wheel for a band saw and for a rotary member coupled to a driver, to accelerate and decelerate the rotation of the driving wheel at a short period to prevent the continuous vibration of the contact portious of the band saw and a workpiece. CONSTITUTION:A rotary member 63, which is driven by a worm 55 and a worm wheel 57, rotates around a hollow fixed shaft 15. A cam follower 53 is put in contact with a cam 70 to drive a wheel 13 for moving a band saw 23. Since the cam 70 is rapidly rotated by a chain 77, sprockets 51, 53, a chain 75 and a sprocket 67, the movement of the band saw 23 for cutting is not constant, in other words, the band saw is slightly accelerated and decelerated at a short period so that forced vaibration is disturbed. For that reason, noises are prevented from being made by the longitudinal vibration of the band saw 23 and its cutting performance is improved. Consequently, the lifetime of the band saw 23 looped around the driving wheel 13 and a driven wheel is lengthened.
