Title: Plasma arc cutting apparatus, manufacturing process and device
Inventor: OMI TADAHIRO
IPC: H01L21/302
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To solve the problems that more than half of currently employed semiconductor processes are performed by decompressed devices, that a cleaning apparatus and aligner can be used only under atmospheric pressure, and that the interface between the devices operated under atmospheric pressure and those operated under reduced pressure cannot be constituted smoothly which becomes a bottleneck for efficient processes. SOLUTION: Plasma containing high-density radicals is formed linearly by using microwaves and damage-free and high-speed film formation, etching and so forth are performed so as to realize continuous machining of wafers or the like. Load locking becomes unnecessary by operating devices under substantially atmospheric pressure and isolating process spaces or the like by a gas flow. Since processes such as film formation, CVD, etching, planarization, cleaning and so forth can be conducted directly by only switching the gas, majority of processes can be performed under atmospheric pressure, thus enabling efficient processes.

Filed: 1993-12-10
Abstract: PURPOSE:To reduce the number of optical components constituting a resonator, constituting a twist mode by using a simple constitution, and obtain a high efficiency laser equipment which oscillates in a single mode. CONSTITUTION:A laser resonator is formed by using a prism 10 in which total reflection is performed a plurality of times, and an output coupling mirror 3. By selecting the number of times of total reflection of the prism 10 and the pickup method of an (s) wave and a (p) wave at the time of total reflection, phase difference of 1/2 wavelength is obtained between the (s) wave and the (p) wave as the linear polarization components which are mutually perpendicular, as compared with the reflected light from a reflecting mirror, when phase difference due to phase shift is canceled and the light inputted in the prism 10 is outputted from the prism along the optical path of incident light. Thereby the function as a 1/4 wavelength plate is imparted to the prism 10 in addition to the function as a high reflecting mirror. A twist mode is formed by the prism 10 and a 1/4 wavelength plate 6.

Title: Operation of steam turbine apparatus at low load level
Inventor: JIYOOJI JIYOSEFU SHIRUBESUTORI
IPC: F22G5/00
Filed: 1989-11-29
Abstract: PURPOSE: To provide a very low load level operation method for a turbine system by increasing the thermal energy supply to the steam in the secondary superheater section only by an amount coordinated with the reduction imparted to the cross-sectional area of the steam flow passage of a division valve. CONSTITUTION: While output pressure of a boiler 6 reaches lower limit value presented by the pressure signals of the line 26, a controller 24 slowly shuts off a division valve 14 based on desired boiler output pressure signals transmitted from line 28, and thermal energy supply to a secondary superheater section 16 is correspondingly increased. By this manner, while the division valve 14 is completely opened, the steam temperature can return to an assigned temperature. Therefore, the boiler pressure does not reduced below a selected lower limit, and the turbine system can be operated under a very low load without shut off the turbine governor valve 18.

Abstract: PROBLEM TO BE SOLVED: To protect a substrate against crackings or chippings and to prevent aggregations/projections due to solder climbing onto the upper surface of a semiconductor substrate by forming a step at the fringe of the substrate and jointing the substrate and a package through soldering. SOLUTION: A semiconductor substrate 1, having a circuit formed on the upper surface, is sliced into a thin film and an L-shaped step 5 is formed in the vertical cross-section of the substrate 1 in the outer circumferential region thereof, while a metal film 2 is formed on all surfaces other than the upper surface. The substrate 1 is jointed to the recess 9b of a package 9 via the metal film 2 by means of a solder 3. When the substrate 1 is mounted on the package 9, the solder 3 climbing from the side face part of the substrate 1 aggregates at the L-shaped step 5 to form a protrusion 6. Since the protrusion 6 of the solder 2 is wetted at the L-shaped step 5, it will not protrude, and the height thereof can be suppressed substantially equally to those of the substrate 1 and the package 9. Furthermore, outer circumferential part of the substrate can be prevented from being chipped and the like by the solder 3 aggregating at the step 5.

Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To layout a product of semiconductor chips at a predetermined position without producing chipping on the surface of the product and warpage on the side thereof. SOLUTION: A guide groove 3 wider than the effective thickness of a cutting blade 11 is formed in advance 1 to 10μm in depth at a cut portion along a cutting line.

The shoulder 3a and the bottom 3b of the guide groove 3 are left at the side of the product to enable produced chipping and warpage not to reach the shoulder 3a. Thus the shoulder 3a can be adopted as a standard of alignment to enable precise alignment.

Abstract: PURPOSE:To provide a regulating method capable of correcting the lateral shear among respective head units, by a method wherein codes for regulating the lateral shear among respective head units are added to data sent from a host computer, which are recognized as data including the codes on the printer side. CONSTITUTION:The data put into respective memories 12A-12D from a host computer 10 are sent to head units 1A-1D corresponding thereto and the recording is carried out by driving respective head units on the basis thereof.
