Abstract: PURPOSE:To reduce the mounting area, to facilitate an inspection of a connected part and to strengthen against heat cycle by cutting inner leads of a bare chip at a position slightly protruding from an outer periphery of the chip, and connecting protruding ends of the leads to a pattern on a board. CONSTITUTION:Inner leads 2 brought at one ends into pressure contact with an Au bump 5 of a chip 4 are held by a carrier tape 1, and cut at a position of about 0.5mm from an outer periphery of the chip 4 by using a laser. As a result, the chip 4 becomes a state that a plurality of the leads 2 protrude about 0.5mm from the outer periphery of the chip 4.

On the wavelength fluctuation detecting part 18, the amount of wavelength fluctuation is computed based on the difference between the signals A and B. Also, on the output fluctuation detecting part 20, the amount of output fluctuation is computed based on the sum of the signals A and E. On an operation temperature control part 3, the temperature of the semiconductor laser 1 is controlled so as to maintain the prescribed operating temperature based on the amount of wavelength fluctuation, and at the same time, the oscillation wavelength of the semiconductor laser 1 is controlled to maintain it constant based on the output fluctuation.

IPC: H01F41/02
Filed: 1979-06-11
Abstract: PURPOSE:To reduce the variation in operating current values by lapping the attracting surface of an iron core with coarse sand, then lapping or polishing with fine sand. CONSTITUTION:The attracting surface of the iron core is lapped with coarse sand of #1,000 and less, then, said surface is lapped or polished with fine sand of #3,000 and more. By this method, the roughness of the surface is made to become about 1-1.4mum. Since convex portions of the attracting surface are removed by this machining, the initial operating current is decreased, and the generation of powder due to the wear of the surface is decreased. The operating current is not increased even through the number of usage is increased.

Filed: 1986-03-31
Abstract: PURPOSE:To improve data transfer capability, by performing an operation to fetch data temporarily from a main memory, and the operation to move the data to a shared memory in parallel. CONSTITUTION:When an access is performed to a main memory 9, an address counter ADC110 designates an address, and the boundary address of the memory 9 is set at an FF11 by a microprocessor 18. The content of a part of the ADC110 is compared with the value of the FF11 at a comparator Cmp12, and when coinciding, the Cmp12 outputs a signal Stop, and stops the readout of a DMA controller 13 from the memory 9. A DMAC214, while a signal Ordy representing the presence of the signal from a FIFO 16 is outputted, reads out the data from the FIFO 16, and controls it to a shared memory 17 through a driver D/R. The address of the memory 17 is designated by an ADC215, and a signal from the DMAC214 is outputted at every completion of a write to the memory 17, and the DMAC113 and the DMAC2 14 are operated in parallel. In such a way, the data transfer capability can be improved without exceeding the boundary address of the memory 9.

Abstract: PURPOSE:To more increase storage capacity than in use of a magnetic material and rewrite the contents in the title storage medium without use of particular cooling medium and cooling device by controlling the amount of oxygen involved in oxide and storing any information utilizing the state of the amount of oxygen being larger or smaller. CONSTITUTION:The amount of oxygen involved in oxide is controlled and the state of the involved amount of the oxygen in the oxygen being larger or smaller is utilized to correspond a change in the state to a signal. Hereby, storage capacity is more increased than in use of a magnetic material and the contents in the title storage medium can be rewrited without use of particular cooling medium and cooling device. Further, although the storage capacity is about the same compared with a storage medium using superconduction and normal conduction transition, there is no need of cooling the medium to low temperature so that it can be used as a storage medium even at room temperature.

Title: Encoder
Inventor: YAMASHITA NOBUITSU
IPC: H04N19/593
Filed: 1989-03-28
Abstract: PURPOSE:To obtain the encoder of high picture quality with simple constitution by arranging sampling points in the shape of a lattice in a field when field off-set sub sample is executed and using the sampling value of a picture element adjacent to a picture element corresponding to the sampling value in a vertical direction as the forecasting value of the input sampling value. CONSTITUTION:A sub sampler 3 arranges the picture elements to be transmitted in the shape of the lattice concerning the respective fields, inputs a local decoding value Vi, which is outputted from a limiter 22, to a 1H delay line 28, executes delay for one horizontal scanning and outputs the value to a subtracter 12 as a forecasting value Pi by the field off-set sub sampling. This forecasting value Pi goes to be the sampling point in the upper direction of one horizontal scanning line to be adjacent in the vertical direction on the picture. Thus, since a forecasting distance is obtained to shorten the force of this execution example rather than a conventional example, forecasting accuracy is improved, distortion caused by quantization is suppressed and the high picture quality can be obtained.
