Patent JP-S62260594-A (JP)
Title: Motor controlling method using inverter
Inventor: OHAMA SHIGEYA
IPC: B60L9/18
Filed: 1986-04-30
Abstract: PURPOSE:To increase am output torque as compared with a slip ratio and obtain a desired high output torque while controlling an increase of motor current by increasing a voltage in a V/f area. CONSTITUTION:A pattern(P3) is a voltage frequency pattern in case of a high tractive force and a voltage V is higher than a usual voltage frequency pattern(P1) in a V/f area which takes a linear function value relative to a frequency f. Therefore, an increase of output torque can be made larger than that of slip ratio and it is possible to obtain a high output torque while controlling an increase of motor current. Accordingly, a temperature rise can be prevented, an inverter control capacity can be reduced and an output torque can be increased.

Title: Method of operating residual capacity of battery
Inventor: YAMASHITA TAKASHI
IPC: H02J7/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a method of operating residual capacity of a battery capable of reducing the estimated error of the residual capacity due to the error of current integration. SOLUTION: Residual capacity is operated (S108 and S109), based on the quantity Ah of charge and discharge obtained by adding up (totaling) the charge/ discharge currents and discharge property (the relation between the discharge voltage V and the quantities Ah or charge and discharge) studied (S100) and stored in advance. It is investigated (S102) whether the possibility of the added-up error having increased over the specified threshold has occurred or not, and in the case that it has occurred, a full charge request signal is issued.  By doing it this way, in the case that there is a possibility of the studied discharge property being transformed largely by the integrated error of charge and discharge currents and a large error in residual capacity estimation being arising in the discharge property type of residual capacity computation method, its warning is issued, so this method can prevented the error in residual capacity estimation from increasing.

Title: Rinsing of through hole in semiconductor device
Inventor: OZAKI YOSHIHARU
IPC: H01L21/3065
Filed: 1980-07-19
Abstract: PURPOSE:To suppress reduction in the thickness of an insulating film and improve electric characteristics by a method wherein a saturated acqueous solution containing phosphate of ammonium dihydrogenphosphate and ammonium fluoride in the specified mixture ratio is used as chemicals for rinsing a through hole made in an insulating film between layers by means of dry-etching. CONSTITUTION:After the formation of an MOS transistor on an Si substrate, an insulating film 5 is formed between layers and a through hole 6 is made in the insulating film 5 through gas plasma etching. As chemicals for rinsing the through hole 6, ammonium hydrogenphosphate and ammonium fluoride mixed with each other in the 1:9 ratio are used. By so doing, contact resistance can be reduced while the expansion of the through hole diameter and the reduction in the thickness of the insulating film between layers are being suppressed. Thus, it becomes possible to increase the minimization of a pattern and improve switching characteristics.

IPC: G01K7/36
Filed: 1988-04-20
Abstract: PURPOSE:To measure a high temperature in a high vacuum environment where no gas is produced by providing a mangetizing unit and gauss meter. CONSTITUTION:A base plate 2 holding a magnetic substance 12 is fixed to a vacuum chuck 1 in a rotatable state. When the base plate 2 stops at the place of a magnetizing unit 4 which magnetizes the magnetic substance 12 by rotation, the magnetic substance 12 is magnetized until it is saturated. At the time of temperature measurement, the magnetization of the magnetic substance 12 provided on the base plate 2 put under a certain temperature condition is measured by means of a gauss meter 3. When the temperature exceeds the curie point of the substance 12, the magnetization becomes '0'. Moreover, when it is checked that which magnetic substance 12 becomes zero in magnetization, the temperature can be recognized or, when the same magnetic substance 12 is used, the in-plane fluctuation can be recognized. Thus high-temperature measurement can be performed in a high-vacuum environment where no gas is produced.

Abstract: PURPOSE: To surely float and remove various inclusions on molten metal with simple constitution by providing an ingate on the bottom surface in the width direction of a molten metal vessel between the mutually spaced pouring-in and out positions of the vessel and burying porous bricks permitting spouting of an inert gas in the entire region of the projecting end thereof.  
     CONSTITUTION: An ingate 5 of a predetermined projecting height is provided in the perdetermined position between molten metal pouring-in and pouring-out nozzle positions 1, 3 within a molten metal vessel TD which pours molten metal poured therein from above such as a tundish out into other vessel or mold. Porous bricks 6 are buried inert gas spoutably in the entire region in the longitudinal direction (coinciding with vessel width direction) of this projecting end part 5a. In this manner, the molten metal flowing along the vessel bottom surface B turns to upward flow by the ingate 5 and an inert gas such as Ar is spouted upward into this upward flow through the bricks 6. This causes said upward current to be uniformly agitated over the entire width thereof, thus the inclusions in the molten metal may be floated and removed with an exceedingly small amount of inert gas blow without distrubing the slag layer on the molten metal surface in the upper part of the blowing position.
