IPC: H02K15/12
Filed: 1979-05-15
Abstract: PURPOSE:To prevent varnish in an armature winding from flowing out for improving its electrical characteristic by reducing the height of the U-shapes insulator in the slot by a specified ratio, and contracting the coil at the slot exit by tight binding the coil with thermally shrinkable tape, before performing varnish impregnation. CONSTITUTION:The height (B) of an U-shaped insulator 3 in the slot is made 10%-40% shorter than the height (A) of the slot shoulder. The U-shaped insulator 3 is inserted into a slot 2, and equipped with random coils 4. Thermally shrinkable tape 6 is sufficiently wound on the U-shaped insulator 3 along its ends at the slot exits 2c. The tape 6 is contracted in the preliminary drying process of the iron core, and varnish impregnation is performed, with the U-shaped insulator 3 and the random coils 4 pushed up to the slot opening 2a side. The constitution permits space between the coils to be smaller, so that varnish is prevented from flowing out, and the electrical characteristic can be improved due to the reduction of leakage reactance.

Title: Head protection circuit of thermal transfer printer
Inventor: KANZAKI TOMONORI
IPC: B41J25/316
Filed: 1986-03-17
Abstract: PURPOSE:To enable a printing head to be protected against an escape state by providing a means to detect an escape/approach state and a means to cut off a voltage to be supplied to the printing head under escape state on the printing head. CONSTITUTION:A switch S2 detects the escape/approach states of a printing head 1 by the rotational operation of an escape/approach mechanism 7 and is opened under escape state. The switch thus installed has one end connected to a head voltage Vh and the other to head resistors r1-rn. The switch 2 is opened and closed according to the escape/approach action, so that a head voltage to be supplied to the resistor r1-rn is turned ON/OFF. Under the escape state, the head voltage is turned OFF and therefore, the resistors r1-rn are not energized even if noises are latched by a latching circuit. In addition, an escape/approach state signal enables the head voltage Vh to be turned ON/OFF by the switch S2 to be detected by resistors R1 and R2 through the division into a preset voltage.

Title: Semiconductor memory test device
Inventor: NOKUBO JIYOUJI
IPC: G01R31/28
Filed: 1984-03-27
Abstract: PURPOSE:To obtain a semiconductor test device which is suited to analyze a fault of a complicated semiconductor memory by using a means which obtains the 2nd address by delaying the 1st address by >=1 cycle and a temporary memory which stores the result of a comparison/decision circuit in response to the 2nd address. CONSTITUTION:The address signal produced from an address signal generator 2 is supplied directly to a semiconductor memory 4 and to a temporary memory 5 via a delay circuit 7. The delay time of the circuit 7 is usually set at an amount equivalent to a cycle of the address signal. As a result, the address signal timing of the memory 5 is delayed by a cycle compared with the memory 4. Thus the address of the memory 5 is equal to the address that is impressed to the memory 4 before a cycle in case a fault is decided in a certain address of the memory 4. Then the faulty address is stored to a TDM.
Patent JP-H01232422-A (JP)
Title: Arithmetic circuit
Inventor: KATSUNO AKIRA
IPC: G06F7/76
Filed: 1988-03-11
Abstract: PURPOSE:To reduce delay and to shorten an arithmetic time and to speed up processing by carrying out normalization and rounding processing in parallel in consideration of added bits. CONSTITUTION:When the quantity of shifting of normalization based upon the arithmetic result of a mantissa part part exceeds the number of added bits, a 1st execution means 19 consisting of a shifter 13, a primary encoder 15, and a LSB circuit 17 shifts the mantissa part and rounds the least significant digit bit of the mantissa part in parallel, and puts them together in one. When the quantity of shifting of normalization is less than the number of the added bits, a 2nd execution part 58 consisting of a LSB adding circuit 31, a rounding circuit 32, and a selector 33 sets the digit movement of the mantissa part caused by the rounding processing previously as the processing result of the rounding and selects one of them. In this case, the rounding process and mantissa part shifting are carried out in parallel. Thus, the normalization and rounding are processed in parallel, so the arithmetic speed is improved.
