Title: Air conditioner
Inventor: HITOSUGI TOSHIAKI
IPC: F25B1/00
Filed: 1989-02-28
Abstract: PURPOSE:To restrict a refrigerant dissolution ratio in a lubricating oil to a predetermined value or below by increasing temperature difference by raising the output frequency of an inverter circuit to increase the capability of a compressor when the difference between the temperature of the lubricating oil of the compressor and the temperature of a condenser is the set value or below. CONSTITUTION:A control part 30 incorporates therein upon heating operation detection temperature To by a temperature sensor 6 (temperature of lubricating oil) and detection temperature Tc by a temperature sensor 14 (condenser temperature) to estimate a difference  T(=To-Tc) of both detection temperature. Further, the control part 30, which has previously stored  T1 as a set value, compared the set value  T1 and an estimated temperature difference T is less than the set value  T1 in the comparison, it shifts up output frequency F from the inverter circuit 21 by a predetermined value alpha. Thus, as the output frequency F of the inverter circuit 21 is raised, capability of the compressor 1 is increased and the temperature difference  T is made greater. Therefore, a refrigerant dissolution ratio in the lubricating oil A in the compressor 1 is restricted to a predetermined value, and satisfactory oil film thickness in the bearing part of the compressor 1 is secured, improving the life of the compressor 1.

Title: High vacuum device and vacuum pump device using the same
Inventor: NAGAI KAZUTOSHI
IPC: H01J41/18
Filed: 1992-02-03
Abstract: PURPOSE:To achieve high vacuum in a vacuum vessel by furnishing a means, which is installed in vessel and ionized the gas, and a means to move the ionized gas in one direction, and by exhausting gas molecules in the vacuum vessel upon ionization and acceleration. CONSTITUTION:A decelerating electric field for electrons is impressed by a DC power supply 28 between an electron accelerating grid 22 and a cylindrical electrode 23. Electrons are thereby decelerated gradually between the grid 22 and electrode 23 to increase the bombardment section area with gas molecules, and ionization proceeds effectively. When the normal gas pressure sinks, gas electro-discharge is not likely to occur between a cold cathode 21 and the electron accelerating grid 22, but the electric discharge lasts and the pumping action is maintained even though the gas pressure in a vessel 25 lowers and the degree of vacuum is enhanced because of existence of the magnetic field by an electric magnet 26. That is, gas molecules to cause drop of the degree of vacuum are ionized, accelerated, and sent back to a vacuum pump 31, which enhances the exhaust efficiency and allows achievement of a high degree of vacuum.

Title: Freezing air-conditioning device
Inventor: KITAGAWA KATSUTOSHI
IPC: F04B39/02
Filed: 1994-03-18
Abstract: PURPOSE:To perform the feed of sufficient lubricating oil to the slide part of a compressor even when a fluctuation in a capacity ratio is produced and the running state of the compressor is changed by a method wherein an oil reservoir is provided as a common use oil reservoir commonly used by a plurality of the compressors. CONSTITUTION:During drive of compressors 3 and 4, lubricating oil 101 in a common use oil reservoir 22 is sucked through oil feed pipes 17 and 18 with the aid of the oil pumps of the compressors 3 and 4. The lubricating oil, by which a slide part is lubricated, is returned through oil return pipes 15 and 16 to a common oil reservoir 22. The oil level of the lubricating oil 101 in the insertion position of the feed pipes 17 and 18 in the common use oil reservoir 22 is held constantly at the same level even when a load fluctuation and the operation state of the compressor are changed. Thus, oil suction performance of the oil pumps of the compressors 3 and 4 is prevented from worsening, constantly sufficiently oil is sucked, and sufficiently lubricating oil is fed to a slide part. This constitution prevents the occurrence of a trouble, such as abnormal wear, the generation of heat, and burning, owing to defective lubrication.

Title: Production of magnetic recording medium
Inventor: SATO HIROSHI
IPC: G11B5/84
Filed: 1988-03-02
Abstract: PURPOSE:To prevent an inadvertent error and to maintain a contact start stop CSS characteristic in a good state by forming a magnetic layer and protective layer successively on a nonmagnetic substrate and polishing the surface of the protective layer with soft buff. CONSTITUTION:The magnetic layer is formed on the nonmagnetic substrate 1 and further, the protective layer 2 consisting of carbon is successively formed thereon. Projections 2a, dust 3, grooves 4 and angles 2b of the grooves 4 exist angularly on the surface of the protective layer 2. The surface of the protective layer 2 is polished by the buff consisting of the soft gauze or cloth. Although the projections 2a and the dust 3 are removed at this time, the flat parts on the surface of the protective layer 2 are not chipped away even if the buff is brought into pressurized contact therewith. Since the buff is soft, the buff moves along the angles 2b and do not inadvertently flaw the angular parts of the angles 2b. In addition, the buff polish the angles 2b round and, therefore, the CSS characteristic is well maintained.

Title: Mos sense amplifying circuit
Inventor: OONO KAZUNORI
IPC: G11C11/34
Filed: 1983-03-25
Abstract: PURPOSE:To eliminate the discontinuous characteristics of access time to the power supply voltage by combining p and n type transistors having gates set at the earth and power supply potentials respectively to secure the working of a triode region of a transistor. CONSTITUTION:The gates of p type transistors TRQ14 and Q15 which form a sense amplifier are connected to each other by a p type TRQ20 having a gate set at an earth potential and an n type TRQ21 having a gate set at a power supply potential and combined with the TRQ20. Therefore if the TRQ20 is changed to a saturated working region or an unsaturated working region from a triode working region owing to the variation of the power supply potential, the TRQ21 is set at a triode working region. Then the triode region is held by combining the TRQ20 and Q21, and the TR works substantially in a triode working region. Therefore the discontinuous characteristics of access time are not produced substantially to the power supply voltage. Thus the sense amplifier can have a stable and high-speed operation.
