Inventor: HAGIWARA MASAHIRO
IPC: C02F1/42
Filed: 1983-03-08
Abstract: PURPOSE:To ensure the washing work to separate anion- and cation-exchange resins from each other, by specifying the central value of distribution in the particle size each of the anion- and cation-exchange resins in such a manner that the central value of the anion-exchange resin is made smaller than that of the cation-exchange resin. CONSTITUTION:The central value of distribution in the particle size of anion- exchange resin is held at 420-600mum, while the central value of distribution in the particle size of cation-exchange resin is held at 500-700mum to make the difference between the central values of said two resins larger above about 50mum. Each of the anion- and cation-exchange resins is sequentially sorted by sieves having apertures of 1,190mum, 1,000mum, 840mum, 710mum, 590mum, 500mum, 420mum, 350mum and 297mum. The total of left-overs is plotted on a logarithmico- normal probability sheet, and the geometric normal deviation of a straight line obtd. by the method of least squares from the plots corresponding to three screen openings where the amounts of leftovers are large is made above 1.3. Hence, the particle size of the resin can be made smaller to obtain condensed water of higher purity.

Title: Hot-water supplying device
Inventor: TAJIMA MASAHISA
IPC: F24S90/00
Filed: 1985-02-26
Abstract: PURPOSE:To increase the heat collecting quantity of a heat collecting device and reduce the capacity of an auxiliary heat source machine by a method wherein frost, adhered to a heat collecting heat exchanger, is defrosted by switching a four-way valve, provided in a heat collecting circuit, to continue heat collecting operation and, simultaneously, an auxiliary heat source heat exchanger is driven. CONSTITUTION:In winter, the temperature of refrigerant, evaporated in the heat collecting heat exchanger 7, is reduced and, therefore, the heat exchanger 7 is frosted and the heat collecting effect thereof becomes insufficient. In this case, the evaporating temperature of refrigerant in the heat exchanger 7 is detected to switch the four-way valve 2. According to the switching, high-temperature and high-pressure refrigerant gas, compressed in a compressor 1, flows into the heat exchanger 7 through a heat collecting pipeline 8 and melts the frost adhered. The refrigerant, passed through the heat collecting heat exchanger 7, passes through a non-return valve 6, heat collecting pipeline 4, the heat exchanger between refrigerant and water and the four-way valve 2 and is induced into the compressor 1 to complete defrosting cycle. When the frost is molten, the four-way valve 2 is switched again to complete a heat collecting circuit. A combustion device 11, attached to the auxiliary heat source heat exchanger 10, is operated to heat additionally the supplying hot-water heated by the heat exchanger 3 between refrigerant and water.

IPC: G02F1/1368
Filed: 1987-02-19
Abstract: PURPOSE:To enable desirable contact properties to be obtained stably without producing an oxide film on the surface of a contact layer, by depositing an active layer of a-Si while raising the temperature from a low level to a higher one. CONSTITUTION:In order to deposit an a-Si:H layer 4 on an N<+> a-Si layer 3, the deposition is initially started at a temperature not lower than a minimum temperature required for deposition of the film. The temperature is raised gradually up to a temperature at which desirable interfacial properties can be obtained between the a-Si:H layer 4 and an SiN layer 5, namely of 200 deg.C-300 deg.C before completing the deposition of the a-Si:H layer 4 and starting deposition of the SiN layer 5. Since the substrate temperature is low enough in the initial stage of the deposition of the a-Si:H layer 4, it is made possible to prevent oxidation of the surface of the N<+> a-Si layer 3 and desirable contact properties can be obtained stably.

Title: Taudeizer correlation code tracking apparatus
Inventor: RUUBIN II MEIN
IPC: H04B1/709
Filed: 1990-02-19
Abstract: PURPOSE: To improve the resolution of a tau-dither correlation tracking device by making the incremental phase deviation between continuous patterns finer than the phase deviation between code clock increments by utilizing a series of tow dither patterns which gradually increase or decrease an average phase deviation. CONSTITUTION: A correlator 10 inputs a clear/acquisition(C/A) code modulating intermediate frequency of the Global Position System(GPS). A code clock is inputted to a PRN code generator 11 through a phase shifter 13 and the generator 11 generates a local code and inputs the code to the correlator 10. The local code is further inputted to an electronic switch 16 through an amplitude detector 15 and the switch 16 outputs either a positive or negative signal in accordance with a control input 19. Then a comparator 22 supplies a state output 23 to a tau-dither controller 24 in accordance with the state of the output of an integrator 21, whether positive or negative.  The controller 24 controls the phase shifter 13 by successively switching tau-dither patterns of states 0-3 though one-increment stepping or delaying strobes 30 and 31 depending upon the state of the output 23, whether positive or negative. Therefore, the incremental phase deviation between continuous patterns becomes finer than that between code clock increments and the detecting resolution of the peak of a correlation function is increased.

Filed: 1987-02-20
Abstract: PURPOSE:To improve the S/N of a reproduced signal and to reduce the cost of a device by arranging an optical attenuator for attenuating reflected light obtained fro the light receiving surface of a photodetector between an optical separator and the photodetector. CONSTITUTION:Light from a light source is partially reflected by a beam splitter 3, converged by a convergent lens 5, made incident upon the photodetector 4 through the optical attenuator 9, reflected by the light receiving surface 41, and made incident upon a beam splitter 8 again through the optical attenuator 9 and the beam splitter 3. Although reproduced signal light from a recording carrier and the reflected light from the detector 4 are superposed to each other in the same optical path, the reflected light is hardly made incident upon the reproducing photodetector because it is sufficiently attenuated by the optical attenuator 9. Thereby, an inexpensive and high performance device can be obtained without expanding the size.
