Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of a circuit simulation by a method, wherein a measured drain current is applied to an third order equation which is obtained by multiplying a specified coefficient with a measured gate voltage for acquiring an optimum coefficient simultaneously and in parallel from a plurality of equations of a first order, and when it is determined that a drain current value is not negative, a drain current model is decided. SOLUTION: In a method for designing this field-effect transistor(FET) model, a drain current, a gate voltage and a drain voltage of the FET are each measured (ST1), and a measured drain current air applied to an third-degree equation, containing a product of a zero-th order to a third order obtained by multiplying a specified coefficient by a measured gate voltage to acquire an optimum coefficient simultaneously and in parallel from a plurality of equations of a first order (ST2). Next, it is decided whether or not a grain current is negative, from a specified coefficient calculated in parallel and at the sometime based on the measured drain current, a gate voltage and a drain voltage (ST3), and when the drain current is 0, the drain current is replaced with a negative (ST4). When it is decided that the drain current is not negative, an FET model is decided.

Title: Abrasion resistant high-cr white cast iron
Inventor: ONO SHIYUUJI
IPC: C22C37/06
Filed: 1977-11-09
Abstract: PURPOSE: A remarkably high abrasion resistant high-Cr white cast iron which is manufactured by the procedure in which a part of Mo of high-Cr white cast iron is replaced with Cu, and V is added to the cast iron.  
     CONSTITUTION: Of the components of a high-Cr white cast iron (based on ASTM- A532-67, for example), a part of Mo present is replaced with Cu so as to include 1.0 to 2.5 wt% Mo and 0.5 to 1.5 wt% Cu, and further 0.2 to 2.0 wt% V is added to the cast iron to form V-carbide. The high-Cr white cast iron with such a composition shows excellent abrasion resistance becuase no crystallization of pearlite takes place even in thick cast iron of a more than 100 mm thickness, as well as having a hardness (HRC) or more than 60 even in its inside.  
     USE: Parts of construction machinery which are liable to abrasion and grinding mills in power station, cement factory, mining, iron works, etc.

Title: Injection molding machine having multi-cylinders
Inventor: NAGASAKA YASUMASA
IPC: B29C45/76
Filed: 1985-06-20
Abstract: PURPOSE:To decrease the rate of rejected moldings, by providing a number of injection cylinders movable by means of position adjusting, by adjusting the position of nozzles in correspondence with the position of each spool of the metal mold and by setting and operating independently the injection molding condition by means of injection controlling. CONSTITUTION:Injection timing of each injection cylinder can be freely adjusted in this machine and a weld is not formed at the smaller thickness part where the mechanical strength decreases as the position of a weldine 54 can be shifted. Flowmarks 62 and sink marks, 63 tend to occur in the case of the injection molding machine of a mono-injection unit, but in this machine, these two defects disappear by elevating the dwell of the gate 64 side and decreasing the injection speed of the gate 65 side by controlling SERVO controlling mechanism 41 and so on in the injection controlling means.

Title: Automatic transaction processor
Inventor: YAMAZAKI YASUMUNE
IPC: G07D9/00
Filed: 1989-05-29
Abstract: PURPOSE:To supply/collect paper money without breaking-down an automatic transaction processor by immediately stopping the supply/collection when a customer is detected. CONSTITUTION:The paper money to be received or dispensed by transaction with the customer are handled by fixed safe boxes 53 and 54. When the transaction to dispense the paper money is frequently executed and the paper moneys of the fixed safe boxes 53 and 54 are lacked, and when a lot of the paper moneys are received and the paper moneys of the fixed safe boxes 53 and 54 are made excessive, the lacked or excessive part of the paper money is compensated from an attachable and detachable safe box 51 and the quantity of the paper money in the fixed safe boxes 53 and 54 is adjusted to be normal. Such a paper money quantity adjusting means is operated by breaking-down the processor during the so-called waiting time, in which the transaction is not processed with the customer. However, a customer detecting means always judges the presence and absence of the customer (the approach of the customer or the start of the transaction by the customer) and when the approach of the customer or the start of the transaction by the customer is detected, the paper money quantity adjusting means is forcibly stopped. Thus, even when the paper money are supplied/ collected by utilizing the waiting time of the customer, the processor can be always set in a state to execute the transaction and the processor is prevented from breaking down by the lack/excess of the paper money.

Title: Production of killed steel
Inventor: OOGAHIRA KAZUO
IPC: C21C5/28
Filed: 1979-10-22
Abstract: PURPOSE:To economically produce good killed steel free from any surface defect by tapping under the undeoxidized state, the molten steel having been melted in an oxygen bottom blowing converter, and reducing the hydrogen content through boiling at the tapping then adding an Al-base deoxidizer. CONSTITUTION:The molten steel having been melted in an oxygen bottom blowing converter has a high hydrogen content because a hydrocarbon cooling agent is used for preventing the erosion of furnace bottom nozzles. Thereupon, this molten steel is tapped in an undeoxidized state, and part of the hydrogen in the molten steel is allowed to dissipate into the atmosphere by the vigorous boiling owing to the inclusion of air etc. by the tapping flow, whereby the hydrogen content is decreased to about <=6ppm. Thence, a deoxidizer comprising Al or Al alloy is added to produce an Al killed steel or Al-Si killed steel. This method does not use any Ar gas etc. for dehydrogenation treatment and since the amount of Al to be used can be made less, this method is economical.

Abstract: PURPOSE:To prevent the loss of the restoration force due to the deformation of a base by using >=2 bases having different elastic limits, containing in a containing box freely slidably for taking out and in and measuring the pressurized state by the difference of the degree of the force added to the base. CONSTITUTION:Pressure gauges 3 and 4 are contained in the containing box 1 freely slidably for taking out and in. The elastic limits of bases or pipe bodies of semiconductor pressure sensors provided respectively in the pressure gauges 3 and 4 are constituted so as to differ from each other, e.g. if the pipe body 5 and a semiconductor element 6 exceed the elastic limit in accordance with an external force, it is designed so that an alarm device is operated and if the external pressure less than the elastic limit is applied, electric current is flowed through conduction terminals 7, 7', or is varied the quantity. Thus, the external pressure is measured by the electric current variation to indicate the numerical value on a display window 2.
