Title: Abnormality detecting method for shape detecting device
Inventor: YAMAMOTO HIROYUKI
IPC: G01L5/04
Filed: 1988-02-10
Abstract: PURPOSE:To detect the abnormality of the shape detecting device invariably stably with high accuracy by setting a decision value according to the total mean value of values of tension signals from detection parts. CONSTITUTION:The tension signals 3a, 3b... are transmitted in the shape detecting device through a common transmission system, so a mean value calculation part 7a calculates a mean value 9a. A mean value calculation part 7b calculates the mean value 9b of tension signals 3c, 3d... and a mean value calculation part 7c calculates the mean value 9c of tension signals 3e, 3f.... Those obtained mean values 9a, 9b... compared with the decision value 11 by comparison parts 12a, 12b..., which output abnormality signals 13a, 13b... when the decision value 11 is larger. Thus, the decision value 11 is compared with the mean values 9a, 9b... to securely detect abnormality occurring to a transmission system and sensor elements which share the transmission system.

Title: Method for wet-cleaning semiconductor substrate
Inventor: SHIROMIZU YOSHIMI
IPC: H01L21/304
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for wet-cleaning a semiconductor substrate, which can eliminate an organic substance and a metal impurity on the surface of the semiconductor substrate and can prevent these organic substance and metal impurity from re-adhering to the surface of the semiconductor substrate. SOLUTION: The surface of a semiconductor substrate is cleaned with a chemical liquid (HCl/O3/H2O/BHF or DHF) in which DHF(diluted hydrofluoric acid) or BHF(buffered hydrofluoric acid) is added to HCl/O3 water. It is preferable that a substance be used such that O3 is annexed to a hydrochloric acid of 5% or less as the HCl/O3 water. Furthermore, it is desirable that the chemical liquid (HCl/O3/H2O/BHF or DHF) be a substance that DHF or BHF of 1% or less is added to the HCl/O3 water. It is suitable to use this cleaning method, particularly for cleaning the surface of the semiconductor substrate prior to the growth of a gate oxide film.

Title: Phase control circuit of ac power using tripod transformer
Inventor: UEDA SHINICHI
IPC: G05F1/24
Filed: 1983-02-24
Abstract: PURPOSE:To eliminate a danger of electric shock and to control the phase in a wide range by controlling the firing angle of a switching element with the output signal of a tertiary coil of a tripod transformer coupled electromagnetically with a firing angle control part. CONSTITUTION:When a switch 17 is opened, transistors TRs Q3 and Q4 are not operated, and a signal voltage is not generated in a tertiary coil 8 at all. But when the switch 17 is closed, a capacitor 20 is charged to make TRs Q3 and Q4 conductive. In this case, since TRs Q3 and Q4 are made conductive while showing a negative resistance, the electric charge of the capacitor 20 is discharged, and a pulse signal synchronized with a power source frequency is generated. A secondary coil 7 is short-circuited by this pulse signal, and a voltage corresponding to this short-circuit is induced in the tertiary coil 8 (360 deg. or less behind the power source frequency) to fire a switching element 14, and a load current is flowed to a load 13. The value of a variable resistance 19 is changed to control the phase in the range of 0-180 deg..

Title: Membrane separator for liquid
Inventor: INOUE HIROSHI
IPC: B01D63/00
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To easily and surely prevent clogging of a permeation membrane and sticking of impurities by providing a membrane separation means consisting partially of a material having piezoelectric property and a means for holding the membrane separation means in an electric field and subjecting the material having piezoelectric property to piezoelectric vibration to remove materials stuck on the membrane surface. SOLUTION: A membrane separation means 10a is provided with a permeation membrane for liquid 3 partitioning a flow passage forming cell 5 into the feed side and permeation side and consisting partially of a piezoelectric material. Since an electric field holding means 10b holds the permeation membrane for liquid 3 in the electric field, it is provided with a pair of electrodes 1, 2 and a power source 4 connected to them. After liquid to be separated is fed from the feed side in the flow passage forming cell 5 and is permeated through the permeation membrane 3 to refine it, it is moved to the permeation side in the flow passage forming cell 5.  At this time, since the permeation membrane 3 placed in the electric field causes deformation or vibration by piezoelectric effect of the piezoelectric material forming this membrane, clogging of the permeation membrane and pollution on the membrane surface can be effectively prevented.
