Title: Production of polyimide prepolymer
Inventor: KADOI AKIRA
IPC: C08G73/12
Filed: 1984-03-30
Abstract: PURPOSE:To obtain effectively a polyimide polymer having a high curing rate and providing a cured molding of excellent heat resistance, by reacting a polyamine with an aliphatic double bond-containing carboxylic acid anhydride in the presence of an oxide of phosphorus in a specified organic medium. CONSTITUTION:In reacting a polyamine of the formula (wherein R is a 2C or higher organic group and n>=2) with 0.52-0.95mol of an aliphatic double bond- containing carboxylic acid or a derivative thereof per mol of the NH2 groups of the polyamine in the presence of an oxide of phosphorus, the reaction is performed in an organic medium which can dissolve reaction materials during at least its initial stage but does not dissolve most of the reaction product. As the polyamine, 4,4'-diaminodiphenylmethane, m-phenylenediamine, or the like is desirably used. As the aliphatic double bond- containing carboxylic acid anhydride or a derivative thereof, maleic anhydride or a maleate ester is desirably used.

Title: Variably controlling method for minimum control lead angle of ac electric rolling stock
Inventor: KINOSHITA SHIGENORI
IPC: B60L7/12
Filed: 1989-03-15
Abstract: PURPOSE:To enable the stable minimum control lead angle (betamin) of a main rectifier to be variably controlled by detecting the commutation overlapping- angle of a motor field rectifier, and by estimating the communication overlapping-angle or commutation constant of the main rectifier through the commutation over-lapping-angle of the motor field rectifier, to set the betamin. CONSTITUTION:By a commutation overlapping-angle detector 81, a natural commutation overlapping-angle uo' in case of the field current value IF of a field rectifier 45 is detected, and through this detected value, the commutation overlapping-angle uo of the field rectifier 45 in the case of the field current IF corresponding to armature current IAF=IA is estimated. First, a commutation constant K is found, and after that, the commutation overlapping-angle uo in the case of IF=IA is found. Then, arithmetic is performed on the betamin of each main rectifier according to the commutation overlapping-angle uo, by a betamin setting device 82, and its value is set as a set value and is applied to each main rectifier. As a result, the stable betamin at a high speed can be variably controlled.

Title: Image data reading system
Inventor: SASAKI ATSUSHI
IPC: G06T1/00
Filed: 1987-03-16
Abstract: PURPOSE:To increase the number of divided parts in one line and to improve the reading accuracy of image data by automatically forming a slice level value by a hardware. CONSTITUTION:Prior to reading out image data, slice level values respectively corresponding to plural divided image signals are previously stored in an FIFO 11 through a selector 10. During the period of image data reading based on a line sensor 1, the oldest slice level value out of plural ones stored in the FIFO 11 is outputted to a comparator 7 every input of a shift clock signal and simultaneously reinputs its output as the up-to-date slice level value. Since the shift clock signals corresponding to the divided number are applied to the FIFO 11, the slice level values corresponding to one period, i.e. one line, can be outputted to the comparator 7 and the image data can be identified by comparing the image signal with the slice level value through the comparator 7.

Title: Field effect type semiconductor device
Inventor: SUZUKI MASAHISA
IPC: H01L29/812
Filed: 1984-03-30
Abstract: PURPOSE:To contrive the reduction of leakage current flowing from source to gate via electrode contact layer by a method wherein an n type electron supply layer is provided with an n type electrode contact layer with a smaller dopant concentration than that of this layer. CONSTITUTION:A non-doped GaAs active layer 2, the n type AlGaAs electron supply layer 3, the n type GaAs electrode contact layer 4, a source electrode 5, a gate electrode 6, and a drain electrode 7 are formed on a semi-insulation GaAs substrate 1. Here, if the dopant concentration in the layer 3 is ND1 and that in the layer 4 is ND2, ND1>ND2. As a result, a depletion layer 9 stretching out of the junction between the electrode 6 and the layer 4 toward the layer 4 becomes thicker, and a leakage current 11 passing through the layer 4 is inhibited satisfactorily, resulting in the suppression of voltage drop in this part. Thereby, an effective field can be impressed from the electrode 6 on a high-resistant layer 2 where a two-dimensional electron gas layer 8 is to be formed. Therefore, the gate withstand voltage improves because of the reduction of the current 11. Besides, the mutual conductance improves.

Abstract: PURPOSE:To readily brake a motor with a reverse phase driving voltage even when the rotating speed of the motor is low to extremely low speed by switching the energizing direction of the driving voltage supplied to the motor on the basis of the comparison of the detecting frequency with an instruction frequency. CONSTITUTION:An error amplifying circuit 9 serves to apply a driving voltage responsive to the error difference between the detected rotating speed from a frequency-to-voltage converting circuit 4 and an instruction rotating speed from a frequency-to-voltage converting circuit 5 to a motor 1. A frequency comparing circuit 10 serves to compare the detected frequency Fm responsive to the detected rotating speed with an instruction frequency Fc responsive to the instruction rotating speed, and controls to switch the current flowing direction of the motor 1 so as to supply a reverse phase driving voltage to the motor when Fm>Fc and to supply a normal phase driving voltage to the motor 1 when Fm<Fc. In this case, the arrangement is so constructed that Fc>Fm is obtained when the detected rotating speed becomes coincident to the instruction rotating speed.

IPC: G06F3/048
Filed: 1986-03-18
Abstract: PURPOSE:To obtain a compact and low cost pulse width/voltage converting circuit for tablet by providing plural voltage holding circuits to eliminate a fast sample holding circuit. CONSTITUTION:A voltage holding circuit 2 keeps a switch SW1 under an ON state during a pulse leading period of a signal X (or Y) and makes a capacitor C3 follow the rectangular wave voltage. Then the voltage is sent to a capacitor C4 to convert the pulse width of the signal X (Y) into the voltage signal for the production of an analog signal having a voltage level corresponding to the input coordinate value. Thus it is not required to use a sample holding circuit that needs a fast operation.
