Title: Sample board for ion milling
Inventor: IGARASHI YOSHIO
IPC: H01J37/30
Filed: 1985-06-07
Abstract: PURPOSE:To prevent spattering yield, by preparing a sample board made of carbon and a sample consisting of a composite of a metal whose outer surface is covered by carbon. CONSTITUTION:An upper plate 1 and a lower plate 2 of a sample board are combined by supports 3, a sample S is installed in a recessed hole 5 of the upper plate, and the whole surfaces of them are covered with carbon 6. Although carbon is attached on the sample by using carbon as the covering material, absorption of electron-rays is little and troubles of observation by a permeable electron microscope are few, since carbon is a lighter element than heavy metals such as molybdenum. Also, for the problem of electron-ray diffraction by the electron microscope or for the analysis problem such as the fluorescent X-ray analyzing, the presence of carbon can be ignored. furthermore, when the sample of an insulator is observed and analyzed, a preliminary process such as the vacuum evaporation of carbon or the like to prevent a charge up of electron- rays is unnecessary, since a thin carbon coating is already placed over the sample.

Title: Auxiliary nozzle for air jet type weaving machine
Inventor: ISHIKAWA HIROHIKO
IPC: D03D47/30
Filed: 1991-05-28
Abstract: PURPOSE:To improve effective action of air jet energy on weft and weft flying force by arranging plural jetting holes of auxiliary nozzle longitudinally from side to side. CONSTITUTION:In an auxiliary nozzle 1 of air jet loom, arrangement of plural jetting holes 2 is constituted in such a way that distance (x) between hole centers positioning at both ends in the nozzle horizontal direction X is longer than distance (y) between hole centers positioning at both ends in the nozzle longitudinal direction Y. Consequently, the center of apparent jetting holes of the nozzle 1 approaches the tip of the nozzle and jet flow more effectively acts on weft. Since the jetting holes 2 are arranged longitudinally from side to side, a wind velocity distribution is flat in the flying direction of weft and jet flow acts so as to increase flying force of weft.

Title: Nonvolatile semiconductor storage device capable of electrical writing and collective erasure
Inventor: KURODA YUKIE
IPC: G11C16/06
Filed: 1993-05-26
Abstract: PURPOSE:To perform writing, readout, and erasure against a flash memory with an EPROM writer without giving any damage to the memory by providing a writer selecting means. CONSTITUTION:A writer selecting means 12 outputs different signals in corresponding to the case where an EPROM writer is selected and another case where a flash memory writer is selected and, when the EPROM writer is selected, outputs a write pulse signal/PGM to a control pulse generation circuit 8. The circuit 8 outputs a control pulse having a width suitable for the writing by the EPROM writer to a write/erasure/readout control circuit 3 and the EPROM writer makes writing. Since the circuit 8 sets the optimum writing time against a flash memory depending upon the write pulse signal/PGM from a control terminal 6c and a signal from a command latch circuit 9, writing to the flash memory can be executed without deteriorating the characteristics of memory cells even when the writing is performed with the EPROM writer.
