Abstract: PURPOSE: To provide water content coulometric determination titration and volumetric titration in a Karl Fischer's method by using solvent containing N-methyl formamide. CONSTITUTION: N-methyl formamide is a favorable solvent to a polar compound, and it generates a high conductive value by dissolved salt. A Karl Fischer's reagent based on N-methyl formamide is, therefore, extremely suitable for a water content coulometric determination method. For example, imidazole 140g is dissolved in N-methyl formamide 1000g. Next, sulfur dioxide 60g is added under cooling, where temperature is kept without exceeding 30 deg.C. Finally, iodine 60g is added, and the solution is left for one night. Its action value (titration quantity) is then defined.

Title: Deflection device for television receiver
Inventor: OCHIAI MASASHI
IPC: H04N3/223
Filed: 1990-07-30
Abstract: PURPOSE:To make the aspect ratio of a screen constant regardless of a change in the brightness by detecting a change in a high voltage current of a picture tube with a DC current flowing to a horizontal deflection circuit and feeding back the detected change to a discharge path of a capacitor of a vertical deflec tion circuit. CONSTITUTION:A loop is formed from a DC power supply E to a reference potential point via a primary winding of a flyback transformer T2, a transistor (TR) Q1 or a damper diode D1, a diode D2 and a resistor R4 and a DC load current IDC flows from the DC power supply E. A voltage drop is generated across the resistor R4 by the DC load current IDC. A voltage changing in a same direction as a change in a high voltage current is obtained from the resis tor R4 and given to a discharge path of an integration capacitor C1 to change the vertical deflection current reversely to a change in the high voltage current, thereby reducing the fluctuation of the horizontal amplitude due to the vertical amplitude. Thus, the vertical amplitude is made almost constant similarly to the horizontal amplitude to obtain a constant aspect ratio regardless of the brightness.

Patent JP-H0256375-A (JP)
Title: Device for detecting medium
Inventor: OBARA KAZUKI
IPC: B41J11/42
Filed: 1988-08-18
Abstract: PURPOSE:To detect the existence of a medium while simultaneously distinguish the type thereof in a thermal transferring recording device by making media reflect the radiating light from a light emitting element and receiving the reflected lights each having different reflecting angle by a plurality of light receiving elements. CONSTITUTION:A medium detecting device 2 has a light emitting element 3 for radiating a radiating light L1 with an incident angle theta1 to a medium 1, a light receiving element 4 for receiving a reflected light L2 with a reflecting angle theta2 (theta2=theta1), and a light receiving element 5 for receiving a reflected light L3 with a reflecting angle theta3 (theta3>theta1). When a medium of high irregular reflection, e.g., an ordinary sheet of paper 1a comes in, since the spreading angle phi1 of irregular reflection is approx. 80 deg., the intensities of irregular reflections L2, L3 which both light receiving elements 4, 3 receive are higher than a defined level causing each detected signal to be H. On the other hand, when an OHP sheet 1b of low irregular reflection comes in, the spreading angle phi2 of irregular reflection is approx. 20 deg., causing only the light receiving element 4 to output H while leaving the output of the light receiving element 5 at L. Thereby, the type of a medium can be also detected enabling the quality of printing to be kept constant.

Title: Rf relay
Inventor: TAMURA YOSHIHARU
IPC: H01H1/20
Filed: 1989-08-08
Abstract: PURPOSE:To eliminate the loss or damage of a high frequency part and the generation of spurious radiation, and to prevent deterioration due to arc by arranging and fixing make contact, common contact, break contact in this order in a linear line, and by forming the length of a contact part of a moving contact longer than a minimum distance between the make contact and the break contact. CONSTITUTION:Since the length l2 of a moving contact 20 is longer than a minimum distance l1 between a make contact 17 and a break contact 19, on the way of its movement, a common contact 18 is in contact with both the make and break contacts 7, 19, with no possibility of opening the central common contact 18. Impedance change can thus be limited to a small value, without the possibility of a load of a transmitter being opened. Also, the deterioration due to the arc generated during the change-over of high frequency large power can be prevented.
