Abstract: PURPOSE:To effect a uniforme and satisfactory embedding in a groove by a method wherein the groove is formed on a semiconductor substrate, an etching- back stop layer is formed in parts other than the groove, a burying material is former and a material whose etching characteristic is different from that of the material is left, by a polishing operation, in a recessed part as a part corresponding to the groove. CONSTITUTION:A groove 2 is formed on a semiconductor substrate 1; an etching-back stop layer 3 is formed in parts other than the groove 2; then, a burying material 4 is formed; after that, a material 5 whose etching characteristic is different from that of the burying material 4 is formed; then, the material 5 whose etching characteristic is different is left, by a polishing operation, inside a recessed part 41 for the burying material 4; after that, the burying material 4 is etched back to achieve that the groove 2 is buried. Since the polishing operation is used, a process is reduced and becomes easy, and grooves having various line widths can be buried uniformly and satisfactorily even when the grooves are buried in order to isolate elements.

Abstract: PURPOSE:To contrive the reduction of pressure loss, the prevention of the generation of vibration and the improvement of heat exchanging efficiency by a method wherein a heat transfer tube is formed by a flat and smooth tube at a desuperheater section, by a tube provided with a high heat transfer coefficient at a condensing section, and by either one of the flat and smooth tube or a corrugate tube. CONSTITUTION:Steam from a turbine flows from a steam inlet port 10 into the desuperheater section C of a heat exchanging chamber 9. In this case, the heat transfer tube 12 of the desuperheater section C is formed by a flat and smooth tube 12A, therefore, the steam flows through the outside of the heat transfer tube 12 without decreasing the flow speed thereof. The steam, passed through the desuperheater section C, enters a condensing section B and heat exchange is effected efficiently between the steam and feed water flowing through the heat transfer tube 12 since the heat transfer tube 12 of the condensing section B is formed by a low-fin tube 12B whereby the steam is condensed into drain. The drain passes through the drain leak section A and is discharged out of a drain outlet port 11, however, the heat transfer tube 12 is formed by the flat and smooth tube 12A, for example, at the drain leak section A, therefore, the drain flows smoothly through the outside of the heat transfer tube 12.

IPC: G06F11/30
Filed: 1987-03-12
Abstract: PURPOSE:To avoid the malfunctions of an equipment due to troubles by detecting the troubles of a microprogram memory and a microinstruction register regardless of execution of a microprogram. CONSTITUTION:A counter 6 is successively counted up before an electronic equipment works. A selector 7 selects the output of the counter 6 and delivers it as an address of a microprogram memory 2. A microinstruction corresponding to said address is read out and fetched by a microinstruction register 3. Then the number of signals of significant levels included in the microinstruction are integrated by an integrator 9. When the counter 6 is counted up to the final address of the memory 2, this fact is detected by a decoder 8. Then the output of the integrator 9 is compared with the output of a register 10 holding the expected value by a comparator 11. If no coincidence is obtained from this comparison, a trouble of the memory 2 or the register 3 is decided. Thus the working of the memory 2 or the register 3 is discontinued.

Title: Disk driving device, and its error recovering processing method
Inventor: KAKIHARA TOSHIO
IPC: G06F3/06
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the error processing time during a reset, by executing a first error recovering processing while controlling a write controlling means if a writing error is detected and executing a second error recovering processing, which is small in the number of execution commands than an error recovering processing(ERP), while controlling the means if a reset instruction is detected. SOLUTION: If a reset is requested, a control section 3 does not execute the ERP, the selector being selected is assumed to be defective, the temporary registration processing of the defective sector is conducted, the assignment of a spare sector is made and the updating of a reassigned table is executed. In the normal ERP having no reset request, many processings are repeated from such a judgement that is not a reset, up to the judgement of an error recovering impossible. Thus, the number of steps, which are actually to be executed, becomes extremely large. Therefore, the time required to execute the processings greatly differs for between the case of a reset is requested and the case in which no request is made for a reset.
