Abstract: PURPOSE:To use the read screw mechanism of the same screw pitch to a drive different in recording density by driving a stepping motor with an exciting phase timing according to the moving quantity of the carriage of a low density or high density recording mode. CONSTITUTION:In an FDD in a high-speed recording mode, a stepping motor 11 is drive-excited by a two-phase step drive system. Consequently, when a step pulse SP is outputted from an FDC 22, a control circuit 20 outputs respective exciting pulses phia and phib to be switched twice according to the pulse SP. Thus, a driving circuit 21 drives the motor 11 by exciting respective exciting phases of the stepping motor 11 with the timings of the pulses phia and phib. In the FDD in a low density recording mode, when the step pulse SP is outputted from the FDC 22, the circuit 20 outputs the exciting pulses phia and phib to be switched four times according to the pulse SP. Thus, by using the read screw mechanism of the screw pitch, the drive control of the motor 11 to execute a double excitation changeover to the high density recording mode is executed, and the moving quantity of the carriage is obtained.

Filed: 1989-04-14
Abstract: PURPOSE:To improve the white balance accuracy by using illuminance information obtained by a stop value detection and illumination information obtained by a fluorescent lamp detection in addition to a color temperature detection obtained by a color difference signal. CONSTITUTION:A correcting circuit 15 provided between a comparative amplifying circuit 14 and a WB(white balance) tracking 17 discriminates illumination conditions (indoor, outdoor, fluorescent lamp, incandescent lamp, etc.), and corrects a WB control signal based on the discrimination result.

Abstract: PURPOSE:To prevent breakage of a cooling-water passageway vessel and to stabilize a laser output by maintaining the temperature of cooling-water drainage below the prescribed temperature irrespective of variations in temperature of city water and in heating power of a laser tube. CONSTITUTION:In case the temperature of a cooling water drainage 8' is below the prescribed  temperature, a cooling water temperature controlling circuit 14 is operated by a detection signal  from a temperature detector 13 and electromagnetic valves 12 and 13' are closed. Therefore, the  cooling water in a cooling water mixing vessel 15 becomes a pressurized cooling water 16 by the  operation of a water pump 11, the generated heat at a laser fine tube 9 is absorbed in a cooling  water passageway vessel 10 and the cooling water is discharged into the vessel 15 as drainage 8.  When the temperature of the drainage 8 exceeds the prescribed temperature while repeating a  heat absorption, a circuit 14 starts operation by receiving the detection signal from the detector  13, an ''ON'' position is given to the electromagnetic valves 12 and 12' and city water 7 passes  through the electromagnetic valve 12 and flows in the vessel 15 as city water 7', thereby reducing  the cooling water temperature in the vessel 15 and maintaining the temperature of the drainage  8', which absorbed the heat generated at the laser tube 9, below the prescribed value. Thus, the  temperature of the cooling water 8 is maintained at the prescribed temperature and below by the repetition of ''ON'' and ''OFF'' of the electromagnetic valves 12 and 12'.

Abstract: PURPOSE:To improve reliability in a vertical treatment technology especially in an annealing treatment by a method wherein a treatment zone, in which an object fluid is subjected to a treatment and a heat insulating zone, in which the object is placed before and after the treatment when the object is taken into and out of a reaction tube, are continuously provided. CONSTITUTION:A sealing cover 14 is fitted to an in-and-out opening 2 at the lower end of a reaction tube 3 so as to be removed freely and a support rod 7b pierces the sealing cover 14 at its center along the axial direction of the tube 3. The support rod 7a has such a structure as to be able to move along the axial direction of the tube while keeping the inside of the reaction tube 3 sealed. By operating the support rod 7b, a wafer 6 placed in the reaction tube 3 can be moved from a treatment zone A to a heat insulating zone B or vice versa with a jig 7. Therefore, after the reaction treatment is completed in the treatment zone A, the wafer 6 is temporarily placed in the heat insulating zone B to be cooled to a predetermined temperature and then exposed to the air so that H-radicals coupled with incommensurate couplers can be given stable coupling status and are not separated again. Thus, an electrically stable semiconductor device can be obtained.

IPC: H01M10/39
Filed: 1990-04-09
Abstract: PURPOSE:To lengthen life as well as to enhance safety by forming a tapered part at least either one of a solid electrolyte pipe and an insulating ring at their junction point. CONSTITUTION:When a tapered section 11a is provided for the end section (upper end section) of glass solder 9 at the negative electrode chamber side, a glass bank is formed. In this case, residual stress in the solder 9 is little in, and even if the surface of solder 9 is corroded by Na or the vapor of Na, strain is hardly concentrated at the junction point between solder 9 and the upper face of the outer circumferential end section of a solid electrolyte pipe 1. This is because the tapered surface is made smooth by grinding, the occurrence of cracks in solder 9 is thereby prevented. By this constitution, it is possible that the glass joint section will never be cracked, the leakage of Na out of negative electrode active material is restrained, and there is neither direct reaction with positive electrode active material nor danger of abnormal over- heating, life can thereby be lengthened, and safety can also be enhanced.
