Title: Method of giving intercrystalline corrosion resistance to spot welding zone of ferrite stainless steel
Inventor: ITOU NAOYA
IPC: B23K35/22
Filed: 1978-11-24
Abstract: PURPOSE: To give intercrystalline corrosion resistance to weld zone by performing long current supply of the specific times the necessary weld time in creating the molten part of a sufficient size at the time of spot welding.  
     CONSTITUTION: In the cace of spot welding of ferrite stainless steel, the long current supply of more than twice the necssary weld time in creating the weld zone of a sufficient size is accomplished. With the weld time of twise or less, the texture change of the weld zone does not take place sufficiently and intercrystalline corrosion resistance is not sufficient and therefore the lower limit is made twice. Hence, the intercrystalline corrosion of the spot weld zone may be prevented without large changes such as sophistication of materials and employment of in-furnace heating.

Title: Semiconductor laser device
Inventor: UMEDA JIYUNICHI
IPC: H01S5/10
Filed: 1979-11-09
Abstract: PURPOSE:To increase output by mounting conductive regions with wide band sections and narriw band sections in parallel along the progressive direction of laser rays. CONSTITUTION:An active layer and a clad layer are set in the same manner as a normal double-hetero type semiconductor laser device. Beltlike conductive regions 116-119 are mounted in parallel in the laser oscillation direction, and wide sections 116A... are formed in about 15mum or less and narrow sections 116B... in about 10mum or less. It is preferable that the wide sections are about 3/8-5/8 times as long as the length of cavities. The minimum intervals of the conductive regions are made not more than width of the wide sections, and about 10-30 conductive regions are formed. According to this constitution, since light distribution is overlapped among mutual wide sections of the beltlike conductive regions when a laser element oscillates and nonlinear mutual action is generated, laser oscillation every each beltlike region has the same wavelengths and phase is kept in a constant relationship, and great output is obtained.

Abstract: PURPOSE:To multiply all speeds, by setting integral multiples of 60 into the multiplied number, in case that the third speed-sequence line is multiplied in time division to sequences where channel basic speeds are 600bits/s and 800bits/s respectively. CONSTITUTION:Between sequence 1 of speed (bis/s) 600, 2,400, 4,800, 9,600 and 48,000 and sequence 2 of speed 800, 3,200, 12,800 and 64,000, 9,600 of sequence 1 is three times as high as 3,200 of sequence 2.

Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To improve the coding compression rate for coded data(CD) by revising the adaptation prediction equation depending on a filter class in the case of output signal conversion when the wavelet transformation is applied to a pre-processing of the DPCM system. SOLUTION: A wavelet transforming unit 1 applies the wavelet transformation to received multigradation image information IPx and provides sequentially multigradation image information IPa and an filter class class information SF with a contact is response to the multigradation image information. A prediction device 25 selects a prediction equation corresponding to the received information SF and calculates the pixel valve of a coding object of interest based on the information IPa and outputs the pixel prediction value IPp to a prediction error computing element 2. The computing element 2 outputs the error EP between the predicted value IPp and the information IPa to an entropy coder 4, in which the error is subjected to entropy coding processing and the coder 4 provided an output of image coding data CD in a prescribed format.  Since the prediction equation used by the prediction device 25 is revised in the way, the coding compression rate of the coding data CD is improved.

Filed: 1988-06-13
Abstract: PURPOSE:To prevent the effect of an erasure signal onto a recording signal by switching the frequency of an erasure signal supplied to an erasure head going earlier than the head recording an FM modulation signal in response to the carrier frequency. CONSTITUTION:The carrier frequency of the FM modulation signal is switched on the magnetic recording medium and the frequency of the erasure signal supplied to the erasure head REH going earlier to heads HA, HB recording the FM modulation signal is switched in response to the carrier frequency. Thus, the erasure signal is set to the signal of the band not used for the demodulation of the FM modulation signal independently of the carrier frequency of the FM modulation signal and it is possible to eliminate the adverse effect on the recording signal by the erasure signal completely. Thus, the FM modulation signal not affected by the erasure signal is recorded independently of the carrier frequency of the FM modulation signal.

A slider 3 which can be moved on an arm 4 can be set in an arbitrary measuring position in the radial direction from a shaft 22 on the face 20, to be measured, of the cast product 8. Then, the displacement amount, of the face 20 to be measured, obtained by making one rotation of the arm 4 at equal angle intervals along an oval track and distance data up to the slider 3 from the shaft 22 are sent to a computer. In the computer, the distance data is converted according to the distance of a measuring position in such a way that the data is measured once on a circular virtual track.  After that, a fundamental component which is obtained by Fourier expansion, i.e., a difference component which is generated when the measuring-system plane is not parallel to the face to be measured, is subtracted from measured data so as to be converted.
