Title: Light control device and light control circuit
Inventor: MIYAGAWA TOSHIYA
IPC: G02F1/035
Filed: 1990-05-31
Abstract: PURPOSE:To suppress the fluctuation in characteristics by a DC drift and to obtain a stable operation by providing bias electrodes near light control electrodes and holding a bias voltage applied at all times between the light control electrodes and the bias electrodes. CONSTITUTION:The control electrodes 15, 16 are formed via an SiO2 buffer layer 17 on the optical waveguide constituting a directional coupler 14. The light control electrode 16 is grounded and a switch power source 20 is connected between the light control electrodes 15 and 16 in such a manner that a switching voltage Vs can be applied by changing over the switch 19. The bias electrodes 18 are formed equidistantly to enclose the light control electrodes 15, 16. A positive bias voltage VB sufficiently larger than the switching voltage Vs is kept applied at all times between the bias electrodes 18 and the light control electrodes 15, 16. A positive bias voltage VB sufficiently larger than the switching voltage Vs is kept applied at all times between the bias electrodes 18 and the light control electrodes 15, 16. The movement of impurity ions to induce the DC drift is suppressed in this way and the fluctuation in the characteristics by the DC drift is suppressed. The stable operation is thus obtd.

The crucible is evacuated to a high vacuum, and an inert gas such as Ar is introduced into the crucible to keep the pressure in the crucible to several hundreds Torr. The powder 2 is sublimed by heating with the heating chamber 4 at 1,800-2,000 deg.C, and the substrate is maintained at a temperature below 2,000 deg.C and lower than that of the powder 2 by 50-200 deg.C to effect the growth of an SiC single crystal on the substrate 3. The pressure of the inert gas is decreased gradually to 1-10 Torr, and maintained at the low pressure to continue the growth of the SiC single crystal. An SiC single crystal having extremely high quality can be obtained by this epitaxial growth process.

Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To quickly investigate the causes of an abnormality including hardware abnormality of a main memory, etc., in addition to program abnormality by preparing a specific abnormality detection means. SOLUTION: Program which are read out of a main memory 3 are stored in sequence into a trace data memory 6 as the trace data by a trace data selection device 4. If an abnormality of program is detected by a program abnormality detection device 7, a trace stop signal is outputted to the device 4 from the device 7. Thus, the storage of trace data is stopped. When an instruction is given from an operator, for example, an output processing means 8 outputs the trace data stored in the memory 6 via a trace data print output device 5. These trace data are used for investigation of the abnormality cause. As a result, the highly effective and reliable trace information can be acquired even in such a failure that the memory 3 has an abnormality that causes abnormal operation of its program.

Title: Curing of concrete
Inventor: MORIGUCHI KISOO
IPC: C04B40/04
Filed: 1987-06-09
Abstract: PURPOSE:To improve the surface smoothness, surface strength and durability of concrete, by using a sheet having a porous plastic film layer having specific air-permeability and water-permeability as a sheet to be placed in a mold. CONSTITUTION:A concrete curing film composed of a porous plastic film layer (or its laminate with a reinforcing layer) having a gas permeability of 10<0>-10<3> sec/100cc and a water-permeability of 10<1>-10<4>l/m<2>.hr under a pressure of 0.2kg/cm<2> is placed in a mold and concrete is cured in the mold. If the air- permeability of the film is <10<0>sec/100cc, fine particle of cement enters into the void of the film layer to deteriorate the surface smoothness of the concrete and the releasability of the film layer. If the air-permeability is >10<3>sec/100cc, the degassing becomes insufficient to generate craters caused by water bubble and air bubble. When the water-permeability is lower than the lower limit, craters are liable to generate in a concrete having high water content similar to the above case and when it exceeds the upper limit, the strength of the concrete is frequency lowered by the generation of cavities caused by the excessive dehydration beyond the necessary level.

IPC: H01L27/12
Filed: 1990-05-31
Abstract: PURPOSE:To prepare at a good yield rate a thinly formed thermocompression bonding wafer having an evenly thickened active zone layer by forming a plurality of concave portions at positions on or along scribe lines of a wafer substrate, followed by forming an oxide film on the wafer, further followed by filling the concave portions with solid substance to flatten the wafer surface, furthermore followed by carrying out termocompression bonding of another wafer substrate to the flattened surface. CONSTITUTION:First, on a scribe line 14 on the surface of a wafer substrate 11, a concave portion 15 is prepared, followed by using the CVD method or the like to form an oxide film 13 in the concave portion 15. The concave portion 15 having the oxide film 13 therein is filled with solid substance 16 such as polysilicon. Next, the flattened surface of the wafer 11 is ground to remove irregularity therefrom, followed by carrying out thermocompression bonding of a substrate 12 thereto. After that, the back of the wafer substrate 11 is ground until the lower end face portion of the oxide film 13 formed in the substrate 11 all appears. Then, a thermocompression bonding wafer with a highly precise thickness of less than 1 mum is obtained, and besides since the oxide film controls grinding as a stopper the thickness of the active zone layer is made uniform, thereby enhancing the yield of wafer.
