Abstract: PCT No. PCT/GB90/00501 Sec. 371 Date Jul. 18, 1991 Sec. 102(e) Date Jul. 18, 1991 PCT Filed Apr. 4, 1990 PCT Pub. No. WO90/12002 PCT Pub. Date Oct. 18, 1990.A potassium salt useful in the production of certain N-substituted alkyl or arylalkyl thionitroethenamines is produced by the reaction of the dipotassium salt of a 2-nitrodithio aliphatic acid such as 2-nitrodithio acetic acid with branched chain primary alkylamines, secondary alkylamines, arylalkylamines or heterocyclic alkylamines such as dimethylamine, pinacolylamine, benzylamine or piperonylamine, thereby converting one only of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated or arylalkylated to produce an N-substituted alkyl or arylalkyl thionitroethenamine. This compound may be reacted with a suitable amine to produce compounds containing the pharmaceutically active grouping -NHC(=CHNO2)NHX, wherein X represents an alkyl, arylalkyl or heterocyclic alkyl group.

Title: Display system of computer or the like
Inventor: SUMIYA TOSHIHIKO
IPC: G06F3/147
Filed: 1980-06-30
Abstract: PURPOSE: To facilitate an easy operation of the exponent key, by displaying the numerical formula supplied to an exponent part where the power of a certain number is shown in a display style of small letters.  
     CONSTITUTION: When a left shift key is pushed in case the cursor display (a) is adjacent to the right of figure 3, the position of cursor shifts to the position of figure 3. Then the left shift key is pushed further and successively to shift the cursor position to an exponent part. Thus a cursor display (b) is transferred to the exponent part. The display (b) at the exponent part is displayed in a different way from the display (a) to facilitate an easy discrimination for the operator. As a result, a display equivalent to a mathematical expression is made possible without using any special sign or symbol.

Title: Drive circuit for inverter
Inventor: TAKAYAMA TOMIO
IPC: H02M7/537
Filed: 1982-05-27
Abstract: PURPOSE:To accelerate the turning ON of a main transistor by supplying as the base current of the main transistor the discharge current of a condenser. CONSTITUTION:When a control transistor Q2 is interrupted, a main transistor Q1 continues ON during the storage time, and the induced voltage of a drive coil N2 in the meanwhile charges a condenser C1 through resistors R1, R2. When the transistor Q2 is then conducted ON to supply the base current of the transistor Q1, the base current is supplied from the condenser C1, thereby accelerating the turning ON of the transistor Q1. Since the condenser C1 is connected through the resistors R1, R2 to the coil N2 when the transistor Q1 is conducted ON, excess current does not flow through the transistor Q1.

Filed: 1984-05-07
Abstract: PURPOSE:To attain the econimical detection for key input with high accuracy without deteriorating the CPU processing capability, by performing automatically the reading and check of the return data and the transmission of scan data when an interval signal is generated. CONSTITUTION:When an interval signal 310 is produced, an I/O processing request control part 305-2 outputs the addresses of a microservice register group 200 onto an internal bus 108. An execution control part 304 reads out the contents of the group 200 and reads return data from an input port 107. Then the part 304 reads the value of the preceding return data out of a key input buffer 103-1 of an address designated by a pointer BFP200-1 and compares it with the value read out of the port 107. When coincidence is obtained from said comparison, the key input state has no change. Thus the increment is fed to the BFP200- 1, and the scan data is shifted by a bit and transmitted through an output port 106. Thus the economical detection is made possible for key input with high accuracy without deteriorating the CPU processing capability.

Abstract: PROBLEM TO BE SOLVED: To hold the position of an exit pupil at a distance place and to shorten the whole length of a zoom lens in a compatible state and to secure aberration performance in a whole zooming range and to secure peripheral illuminance at a wide-angle end in the compatible state by constituting a zoom lens of a 1st group having negative power and a 2nd group having positive power in turn from an object side and satisfying a specified condition. SOLUTION: This zoom lens is constituted of the 1st group Gr1 having the negative power and the 2nd group Gr2 having the positive power in turn from the object side. Besides, it is constituted so as to satisfy the conditional expressions of 0.1<|f1/f2|<Z<0.39 and 0.8<|f1/fw|<2.15. Provided that f1 shows the focal distance of the group Gr1, f2 shows the focal distance of the group Gr2, Z shows a zoom ratio and (fw) shows the focal distance at the wide-angle end. Thus, since the ratio of the focal distances of the groups Gr1 and Gr2 is properly set with respect to the zoom ratio, the position of the exit pupil is held at the distant place and the whole length is shortened in the compatible state. Besides, image quality is enhanced and the lens is made inexpensive by reducing the number of lenses.
