Patent JP-S6358114-A (JP)
Title: Electromagnetic flow meter
Inventor: TOMITA TOYOFUMI
IPC: G01F1/60
Filed: 1986-08-28
Abstract: PURPOSE:To enable highly accurate measurement of flow rate, by discarding the flow rate signals containing a large noise or removing the noise with a filter. CONSTITUTION:A magnetic field 2 is applied to a fluid to be measured flowing through a tube 1, an electromotive force corresponding to the flow velocity thereof is detected 3 and then a flow rate signal is outputted from a detection means 3. The flow rate signal is A/D-converted 6 to be read into an abnormality value decision means 7 and when it is decided to be an excessive signal beyond a specified value, the digital signal is discarded while an abnormality signal is outputted. In this manner, the outputting of accidental excessive noise component is blocked to prevent the generation of measuring errors. Then, the frequency of occurrence of the abnormality signals is counted with an abnormal value frequency decision means 8 and when counts per unit time exceed a specified value, a switching means 5 is turned to the filter 4 side. This allows a flow rate signal to be inputted into the converter 6 after being passed through the filter 4 to block the outputting of excessive noise components frequency generated, excluding the normal frequency components of flow rate signals, thereby preventing the generation of errors and the disabling of measurement.

Title: Nonvolatile semiconductor memory device
Inventor: KIM JIN-KI
IPC: G11C7/00
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To automatically optimize a data writing state by automatically repeating writing and verification until all cells which are selected with a page buffer by one time input without external control are optimally programmed. SOLUTION: Since 0 data which are loaded to a positive output terminal with a bit line latch circuit LT are inverted into 1 data and the 1 data of a negative output terminal become the 0 data, a pull down transistor PD1 in a writing state detecting circuit PS is turned off. When the page buffer PB, i.e., the data of a negative output terminal bar Q in all latch circuits become a 0 state by this repeating operation, that is to say, all 1 data first inputted are inverted into the 0 data, a detecting signal ϕ5 of the writing state detecting circuit PS becomes H level, i.e., VCC level, whereby it is shown that the cell selected in accordance with given input data is written in an optimal state.

Abstract: PURPOSE:To quickly cope with fuel transportation delay, and to make real inlet fuel quantity in a cylinder coincide with the target value at all times by taking some means to connect a compensater having the transfer characteristic reverse to the transfer characteristic of the plant to the plant in series. CONSTITUTION:A fuel injection control block is provided with an adaptive controller, and this adaptive controller makes a model as a state variable, which represents behavior of the fuel, by using the fuel quantity stuck to an inlet pipe of an internal combustion engine, and thus identifies and regulates parameters of a transfer function in a plant so that the real inlet fuel quantity in a cylinder coincides with the target inlet fuel quantity in the cylinder. In this case, a compensater having a reverse transfer function is connected to the plant in series, and corrects the parameters of the transfer function in compliance with predetermined characteristic according to a running state of the internal combustion engine. On the other hand, a plant including a compensater is assumed. When the transfer characteristic of this assumed plant is deviated from the neighborhood of 1, an adaptive controller is operated so that the transfer characteristic of the assumed plant and the adaptive controller come within the neighborhood of 1.

IPC: A61M16/10
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To reduce the patient's electricity rate burden by changing the power supply voltage to be supplied to an oxygen thickening device by a power supply voltage changing means. SOLUTION: The oxygen thickening device is provided with the power supply voltage changing means 8, by which the power supply voltage supplied thereto is changed. A switching batter, transistor, etc., are used for the power supply voltage changing means 8 to control a household or commercial power source of 100 V to 80 to 95 V, further preferably to about 85 to 90 V. The use environment of this case fluctuates largely with areas, seasons, etc., and load is acted on a compressor 1 at the time of low temperature and, therefore, when the voltage is lowered, there is a possibility that the compressor locks. The temperature of an adsorption bed 2 is, therefore, detected by a temperature detecting means 6 and the power supply voltage is dropped under the conditions under which the temperature of the adsorption bed 2 is >=5 deg.C, further >=10 deg.C or the temperature of the compressor is about <=10 deg.C. Energy conservation is thus made possible.

Title: Forming tube for extrusion-molded resin pipe
Inventor: WADA HIROSHI
IPC: B29C48/32
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To improve the cooling efficiency and the extrusion rate and further enable the continuous production to be performed by forming a helical groove through which a cooling liquid is made to pass, in the inner wall face of a forming tube. SOLUTION: A helical groove 11 for the passage of a cooling liquid is, for example, formed in the inner wall face of a forming tube 1. Further the forming tube 1 makes the cooling liquid pass in an arrow direction when a resin pipe 2 extruded from an extrusion machine is allowed to pass, so that the cooling liquid comes into contact with the resin pipe 2 directly. Thus the forming tube 1 is used in such a state that the cooling efficiency is increased. Consequently the cooling efficiency is enhanced to be able to increase the extrusion rate. Alternately a groove for the passage of a solvent is formed across the peripheral direction of the inner wall face of the forming tube 1. A bleedout is dissolved by flowing the solvent through the groove and therefore, no deposit is accumulated on the inner wall face of the forming tube 1.  For the described reason, the continuous production of the extrusion-molded resin pipe 2 is realized as the molding operation need not be suspended each time for cleaning.

Title: Cassette for semiconductor wafer
Inventor: ANAMI YOSHIBUMI
IPC: B65D85/38
Filed: 1986-08-27
Abstract: PURPOSE:To prevent erroenous insertion by mounting a member with a pectinate projecting section, which is not brought into contact with a wafer when the wafer is inserted normally into a cassette and is brought into contact with the wafer and conducts the operation of the obstruction of insertion when the wafer is inserted erroneously under the state of double levels. CONSTITUTION:When wafers are inserted normally, all the wafers 3a are stored in a cassette because the wafers 3a are introduced into grooves 5 in a member 2. When the wafers are inserted erroneously at double levels, the wafers 3b are not admitted into the grooves 5 in the member 2 and collide with the nose sections of projections, and the wafers 3b are exposed outside the cassette 1. Consequently, the wafers projecting outside the cassette can be discriminated as erroneous insertion. Accordingly, the confirmation of the presence of erroneous insertion and the specification of the erroneously inserted wafers are enabled and facilitated.
