Title: On-sea-welding method
Inventor: ISHIMOTO KEIICHI
IPC: B23K9/00
Filed: 1979-04-06
Abstract: PURPOSE: To eliminate th possibility for the occurrence of corrosion and eliminate the need for painting even if scorching occurs in the built-up range and its surrounding by securing the sheets composed of corrosion resistant materials to the portions near the welding point of a structure floating on water.  
     CONSTITUTION: The steel plates 1 constituting the bottom of a floating structure such as ship are positioned always under water surface and the steel plates 1 are welded and bonded at the groove part 2. More specifically, stainless steel sheet materials 3 are secured near the groove part 2 of the steel plates 1 by, e.g., clad welding. No painting is applied to the mounting portions of the stainless steel materials. At the welding, first the water near the weld zone is removed by way of a hollow chamber or the like. Next, a backing 4 is applied to the bottom of the groove part 2 and welding is done while the dropping-away of the welding materials is being prevented. As a result of this, even if the scorched portions of the stainless steel are produced, there is no possibility for causing corrosion and since there is no need for painting, the considerable cost reduction may be achieved.

Abstract: PURPOSE:To reduce the occurrence of small white lines in the boundary of blocks by lenthening the electrification time for dots in the boundary of adjacent blocks of different print timings in the heating resistor row of facscimile, etc. CONSTITUTION:The output time for outputs from the 2nd to the 31st, among picture signals of dots of a block 32 stored in a shift register 4, is controlled by signals from a terminal 3 after the output is given to AND gates 7-1-7-30. Also, the 1st and 32nd dot outputs to be the boundary of the blocks are directly given to a dot driver 6. When all black is printed in designated blocks by the driver 8, the 1st and 32nd dot outputs become high level during the time T2, and on the other hand, the dot outputs from the 1st to 32nd become high level during the time T1. Thus, on the basis of T2>T1, the lowering of temperature in the boundary of the blocks is compensated and the occurrence of white small lines is reduced.

Title: Production of inverted shape working data
Inventor: SEKI MAKI
IPC: G05B19/4093
Filed: 1989-02-23
Abstract: PURPOSE:To obtain the inverted shape NC working data which is more precise than that obtained with use of an offset vector by making use of an interference checking processing to obtain the NC data for rough working of the inverted shape of a digitized model. CONSTITUTION:It is checked whether a contact position is equal to the first position of a mesh M (i, j) or not. If so, the Z axis coordinate value of the contact position is stored in a memory area of the mesh M. If not, the Z axis coordinate value stored in a memory area corresponding to the mesh M is compared with the detected Z axis coordinate value. The Z axis coordinate value is stored only when the latter coordinate value is larger than the former one. This processing is carried out every time the stylus position data is digitized. Thus the coordinate value having the largest point of the Z axis coordinate value among those points belonging to the mesh M is stored in each memory area of a working memory 1d corresponding to each mesh M. Then a mesh surface S (i, j) is obtained.

Abstract: PURPOSE:To increase the selecting performance of wavelength for an optical coupler, by controlling the transmission constant of the optical waveguides made of the electro- optical material and nonelectro-optical material respectively and via a grating electrode and an auxiliary electrode. CONSTITUTION:A channel type optical waveguide 11 and a slab type optical waveguide 14 made of a nonelectro-optical material are formed on an electro-optical substrate 10 by the Ti diffusion, etc. The transmission constant of these waveguides 11 and 14 are controlled so that the Bragg conditions is satisfied by the periodical change of the refractive index in the waveguide 11 when the voltage is applied between a pair of comb-shaped grating electrodes of a buffer layer 15 coated on the waveguide 14. As a result, the matching of phase is possible, and the waveguides 11 and 14 are firmly coupled to the beam of the corresponding center wavelength. On the other hand, if the wavelength of an incident beam is deflected from the center wavelength, the refractive index of the waveguide 12 varies by controlling the electric field via a pair of electrodes 12 on the substrate 10. At the same time, the transmission constant is controlled so as to satisfy the Bragg conditions to the corresponding wavelength. Thus an optical coupler having the increased selecting performance of wavelength is obtained.
