Title: Semiconductor integrated circuit device
Inventor: NISHIUMA MASAHIRO
IPC: H01L29/92
Filed: 1985-08-26
Abstract: PURPOSE:To minimize wiring-caused parasitic capacity by rendering an interlayer insulating film thicker than a MIM capacitor insulating film and thereby to increase the capacity per unit area of the MIM capacitor by a method wherein the interlayer insulating film has a two-layer laminate in structure and the MIM capacitor insulating film is built of one of the two layers only. CONSTITUTION:Si ions are implanted into a semi-insulating GaAs substrate 4 for the formation of an implanted layer 5. A lower electrode wiring layer 6 to constitute a lower electrode of a MIM capacitor and metals for an FET and a resistance element are built of AuGe/Ni/Au. Further, the gas electrode 7 of the FET is built of Ti/Al. At this stageof the manufacturing system, insulating films are formed. First, a 5,000Angstrom -thick SiO2 film is formed by CVD to be a first layer insulating film A11, the SiO2 film is then removed from the region for the MIM capacitor, and then a 3,000Angstrom -thick Si3O4 film is formed by plasma CVD to be a second layer insulating film B12. Thereafter, an upper electrode wiring layer 9 containing the upper electrode of the MIM capacitor is built of Ti/Au.

Title: Casting mold made of cast iron having two-layered structure for steel ingot
Inventor: NAKAMURA SHIROU
IPC: B22D7/06
Filed: 1983-10-03
Abstract: PURPOSE:To prevent generation of a tone sheet in the stage of removing a steel ingot from a mold for casting a steel ingot by using thinly a material which is different from the material of the mold and has a low yield point to constitute the part of the lower inside surface of the mold where the tone sheet is liable to arise. CONSTITUTION:A core 9 for forming the inside surface of a mold for casting a steel ingot is erected on a flat plate-shaped drag 8 and a master mold 10 is disposed to form a space 12 for forming the mold to enclose said core mold. A cast iron for the casting mold is then poured through a runner 11 and a sprue 13 into the space 12 to cast the mold. A mold coating material 14 mixed with powder of ferrosilicon is used in the part of the lower outside circumferential surface of the mold 9 where a tone sheet is liable to arise. The molten cast iron poured into this part forms the material consisting primcipally of ferrite having a low yield point to 0.2-1mm. thickness as the cementite in the pearlite base is decomposed to ferrite and graphite by ferrosilicon. The generation of the tone sheet on the lower inside surface of the mold is obviated in the stage of drawing the steel ingot cast by using such mold.

IPC: G02B6/10
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To write Bragg diffraction gratings into an optical fiber. SOLUTION: This method includes a process for manufacturing the Bragg reflection diffraction gratings using a phase mask and an amplitude mask device for manufacture of a Bragg reflector. The Bragg reflection diffraction gratings have the periods larger than the periods of the conventional short period diffraction gratings but much smaller than the periods of the conventional long-period diffraction gratings. This short-period Bragg reflection diffraction gratings have periods in a range of, for example, 1 to 10 μm. The method of manufacture includes the arrangement of the amplitude mask having internally formed suitable slits on a photosensitive waveguide to be manufactured, then irradiation of the waveguide through the slits and the consequent introduction of the periodic patterns of refractive index fluctuations which are the characteristic of the Bragg reflector by light.  The short-period Bragg diffraction gratings generated by this amplitude mask are the reflection diffraction gratings having the reflection characteristics attaining nearly 99.99%. The reflective diffraction gratings manufactured according to this method are advantageous in applications, such as adding and decreasing of channels into a wavelength division multiplex system and the detection of the stabilization and structural imperfectness of a laser.

Filed: 1990-07-13
Abstract: PURPOSE:To keep the frequency of a reproduced FM signal and a period of a horizontal synchronizing signal the same as that in the normal state at special reproduction by changing a clock frequency when a reproduced video signal is written in a memory from that when it is read from the memory at the special reproduction. CONSTITUTION:A control signal on a tape is detected by a control head 5 at special reproduction, a counter 6 measures its time interval and a microprocessor 7 calculates the period of a horizontal synchronizing signal of a video signal reproduced. A PLL 9 generates a clock having a period of 1/910 of the calculated period, an A/D converter 10 samples the video signal by using a clock obtained from the PLL 9 to convert 1H period of the video signal into 910 sets of data. Since the read of the data is implemented synchronously with the clock of a period being a period of 1/910 of the usual horizontal synchronizing signal, the period of the horizontal synchronizing signal of the outputted video signal is the same as that at normal reproduction.

Abstract: PURPOSE:To provide ink cells having narrow widths on an elastic body at a high accuracy by a method wherein the land part formed so as to surround the ink cells is formed by separating and transferring plating which is applied to the nearly mirror-finished surface of electrically conductive board. CONSTITUTION:Onto a mirror-finished electrically conductive board 1, electrical insulator, on which positional pattern having the desired arrangement of ink cells, is pasted. After exposure is carried out under the condition that the film original, on which the desired pattern is formed, or the like is brought into close contact with the insulator, development is carried out by exclusive developer so as to form exposed part left. Under the condition that the rear surface of the board and the part dispensing with plating in the surrounding of the ink cell are masked by electrically nonconductive stock, plating is applied on the exposed part of the electrically conductive board 1. After that, remaining electrical insulator is removed by stripping liquid and then adhesive 4, the adhesion of which is stronger than that between the plating 13 and the electrically conductive board 1, is applied on the plating. After the adhesive is dried to adhesive-bondable state, the plate 13 and the elastic body acting as an intaglio plate board 3 are opposedly pressure-bonded together. By peeling the electrically conductive board 1 and the intaglio plate board 3 off each other after the hardening of the adhesive 4, the plating 13 is separated from the electrically conductive board 1, resulting in transferring the plating 13 to the intaglio plate board 3.
