Title: Recovery device of waste heat from electrical equipment
Inventor: ASAKURA AKIRA
IPC: F01K27/02
Filed: 1979-04-25
Abstract: PURPOSE: To effectively collect and utilize the heat discharged from an electrical equipment, by practically combining a heat exchanger worked by the use of evaporating refrigerant liquid of low boiling point with facilities of using LNG.  
     CONSTITUTION: Cooling liquid at a high temperature deriving from a cooling operation for a winding 2 of a rotary electric machine 1 is fed to an evaporator 9 by a pump 4 and returned to the rotary machine 1 after evaporating refrigerant liquid of low boiling point in the evaporator 9. The evaporated gas of low boiling point is fed to a turbine 12 that drives a generator and wastes its power to a power device 13. Exhaust gas from the turbine 12 is fed to a condenser 14, cooled by LNG, liquefied and collected. The condensed refrigerant liquid is pressurized by a refrigerant pump 10 and fed to the evaporator 9. A liquid level of the evaporator 9 is held at constant by a refrigerant control valve 11 to supply the refrigerant corresponding to its amount of evaporation to the evaporator 9. The LNG in a storage tank 16 is fed to the condenser 14 by an LNG pump 15, here permitted to absorb heat, vaporized and supplied as the fuel for an electric power generation boiler 17.

Title: Rotary head type digital audio reproducing device
Inventor: YOKOZAWA SEIICHI
IPC: G11B15/467
Filed: 1987-03-06
Abstract: PURPOSE:To prevent capstan servo from getting disorder by supplying no signals to the capstan servo at a time when the variation in the level difference between crosstalk due to the pilot signals of both neighboring tracks is large. CONSTITUTION:When the tracking is stable i.e. Q output of an FF D11 is at an L-level, an AND gate D14 turns off. At this time, if the level difference between the crosstalks due to the pilot signals of the both neighboring tracks is double or three times of the level of an ATF error signal, an AND gate D13 turns off even though a pilot signal for on-tracking is correctly detected because the output of a comparator A10 comes to an L-level. Therefore, a sample pulse GP1 outputted from a controller and timing generator D8 is not impressed to an S/H circuit A11, hence, at the same time, a track shifting length is not outputted to the capstan servo as an ATF error signal. This means that the disorder of the capstan servo because of the interference of a pilot signal remaining after erasing due to an over write, can be prevented.

Filed: 1982-03-31
Abstract: PURPOSE:To record and reproduce a frame signal to and from a small-sized magnetic sheet, by a simple head feed mechanism, by setting an interval of two magnetic heads provided in parallel to a specified value or above of recording area width. CONSTITUTION:For instances, width 2b of a recording area of a magnetic sheet is selected to 8mm.. When track width containing a guide band is set to 8mum, 100 fields can be recorded in the recording area 2b. When an interval of two magnetic heads 3', 3'' is set to 4mm., 50 fields can be recorded, and by switching the heads, 100 fields can be recorded. In case of recording a frame signal, the two magnetic heads 3', 3'' are used by dividing them into even and off fields, and 50 frames can be recorded. In this case, the magnetic head feed mechanism feeds the magnetic heads 3', 3'' by 80mum each of one track pitch at every frame. In this way, when an interval of mutual magnetic heads is set to 1/n of a recording area of a magnetic recording medium, it becomes possible to record and reproduce a frame signal to and from a small-sized magnetic sheet by a simple head mechanism.

Abstract: PURPOSE:To control plasma spectral intensity with high reliability by enclosing a target with a partition wall opened only at the place facing a substrate and measuring the plasma spectral intensity from a slit provided on the partition wall. CONSTITUTION:The target 1 in a vacuum vessel 8 is enclosed by a shielding box 3 opened to face the substrate 4. The slit 5 of 0.3 to 2mm spacing is provided on the side face of the shielding box 3. A plasma spectral intensity measuring sensor 6 is provided on the outer side of the shielding box 3 and the optical axis of the sensor is aligned to the position where the plasma light generated on the target 1 passes most long at the center of the slit 5. The plasma spectral intensity is measured and the value thereof is fed back to an O2 flow rate control device 10 which introduces this value during the process. The plasma spectral intensity is so controlled as to be kept constant. The plasma spectroscopic measurement of the high reliability is thus executed without receiving the influence of splashing materials.
