Title: Optical disk and its recording method
Inventor: MATSUMOTO HIROYUKI
IPC: G11B7/24073
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To decrease thermal crosstalks and to further decrease noises by specifying the difference in level between land parts and groove parts to >=100nm, thereby prolonging the heat propagation distance to adjacent tracks. SOLUTION: Plural optical disk substrates in which the differences in level between the lands and the grooves have various values are prepd. These substrates are set in a sputtering device. Protective films consisting of silicon nitride are formed at 70nm film thickness, magneto-optical recording films consisting of TbFeCo at 50nm film thickness and protective films consisting of silicon nitride at 70nm film thickness are successively formed on these substrate surfaces, by which the magneto-optical disks are produced. These magnet optical disks are set in a recording and reproducing device. After marks are recorded on the measuring tracks, the marks are erased 100 times under tracking by offsetting to the side nearer the measuring tracks by 0.05μm from the adjacent tracks.  The phenomenon of the thermal crosstalks is not observed at the difference in level of >=100mm when the change rate of the carrier of the recording marks of the measuring tracks is measured thereafter.

IPC: B29C48/67
Filed: 1989-12-07
Abstract: PURPOSE: To obtain a good degassed product without making the structure or manufacture of the subject extruder expensive by providing a disc having a specific thickness and a profile on a back portion of the disc directed toward an inner cylinder of an extruder. CONSTITUTION: Discs 5 each having a thickness of 0.1 to 0.5 D (D is a diameter of a screw) are alternately provided at spacer members 6 at a lower side of a degassing port 4. Intermediate spaces 16 to 22 are opened between the discs 5 and the members 6. A melt to be degassed is fed from screws 12, 13 to, for example, the space 16, and then arrived at next space 17 at opposed side. In a next lapse, the melt is fed to the spaces 18 to 22 via a groove 9 and the back part 15 of the disc. Accordingly, it is reciprocatingly conveyed from the disc on one coupling rod 14 to the disc provided on adjacent coupling rod 13 and hence a very thin melt layer is formed. Gaseous monomer residue and the like are removed from these layers.

Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a residence, in which the appearance of an exterior wall section can be improved by reducing the interrupting of a joint pattern without increasing the kinds of throatings. SOLUTION: In sash frames 12 of windows 11A, the vertical size of outdoor exposed sections exposed to the outdoor sides of opening sections 8 is set at the 11 times of vertical base size M.

Title: Connection intermediate body of inner lead and electronic part and manufacture thereof
Inventor: ASAI TAKUJI
IPC: H01L21/60
Filed: 1989-12-06
Abstract: PURPOSE:To connect fined inner leads and the external connecting terminals of an electronic part positively and easily by forming bumps to connection intermediate body itself for connecting the inner leads and the electronic part. CONSTITUTION:Bumps 13 for connecting inner leads 30 and the connecting terminals of electronic part 40 are held in the support holes 12 of a connection intermediate body 10 completely apart from the inner leads 30 and the electronic part 40. Consequently, the bumps 13 are held in the support holes 12 by surface tension when they are melted, and are difficult to flow to the outside. As a result, even when pitches among the inner leads 30 and among each connecting terminal of the electronic part 40 are reduced, the molten bumps 13 are not brought into contact with the adjacent inner leads 30 and connecting terminals, and another connecting is not short-circuited to an inner lead 30. Accordingly, the fining of the inner leads 30 and the connecting terminals of the electronic part 40 can be attained sufficiently.

Title: Method for compressing band width of digital code
Inventor: WATANABE YUKIHARU
IPC: H04L27/12
Filed: 1991-09-26
Abstract: PURPOSE:To enable K band width compression of a digital code with simple configuration by using a code change detection distributer, an oscillator having five oscillation sections (threshold level setting section) and a band pass filter for the method so as to use a stepwise code. CONSTITUTION:This method consists of a code change detection distributer 2, an oscillator 3 having five oscillation sections (threshold level setting section) and a band pass filter 9. In this case, when a digital binary code 1 being information is transferred to the code change detection distributer 2, the code change detection distributer 2 detects a code change in digital binary code and its output is transferred to the oscillator 3 in the order of individual oscillators 6, 5, 4, 5, 6, 7, 8, 7, 6. Then the oscillator 3 gives outputs of f0Hz, (f0+280Hz), (f0+400Hz), (f0+280Hz), f0Hz, (f0-400Hz), (f0-280Hz), and f0Hz, and they are transferred to the band pass filter 9. The band pass filter 9 applies waveform shaping to them and outputs a stepwise SFK signal. In this case, a transition frequency of the SFK (including carrier f0) is set to 5 as its threshold value.

Title: Response system for incoming call
Inventor: ENDO KOJI
IPC: H04Q3/58
Filed: 1992-11-27
Abstract: PURPOSE:To display the title of an incoming call destination or the like simultaneously with an incoming call by the sub address number of PBX direct inward dialling. CONSTITUTION:When an operator inputs tone sub address number and the title of the incoming call destination from a KBD 122 to a DTE 120, the sub address number of PBX direct inward dialling and the title of the incoming call destination are registered in a MEM 123 as a FL 124. A SUB 6 originates a call addressed to a DTRE 100 by PBX direct inward dialling through a NW 5 to a DPBX 10. A CCE 2 transfers the sub address number through a TRK to which the call has come into, control signal lines 11 and 12 and a DLC 3 to the DTRE 100 and instructs an incoming call processing at the same time. A DCE 110 performs the incoming call processing and at the same time, informs the DTE 120 of the sub address number. The DTE 120 reads the title of the incoming call destination from the FL 124 inside the MEM 123 by the sub address number of PBX direct inward dialling and displays it at a DPY 121.

The standard of the ferritic stainless steel sheet is 0.3-1.0mm as the thickness is order to be usually an end product as it is. Thereby, density of  100} texture is reduced and the ferritic stainless steel sheet excellent in r value is obtained. Further, the heat treatment and rolling processes following the process annealing is able to be omitted and accordingly the manufacturing cost is able to be reduced.
