Abstract: A demodulator for code-division multiple-access spread-spectrum communications stores received chip data in a separate memory area for each transmitting station. Each area has a capacity of at least two symbols. When a complete symbol is received from a transmitting station, all chip data stored in the corresponding memory area are correlated with the corresponding spreading code, and estimated symbol values are derived from the correlated values. The correlated or estimated value of the oldest symbol is output as a demodulated value. The difference between each estimated symbol value and the previous estimate for the same symbol is multiplied by the spreading code to generate remaining interference values, which are subtracted from all chip data stored in memory areas for other transmitting stations, thereby updating those data.

Abstract: An apparatus for coating a glass ribbon has an exhaust on each side of a coating unit at different distances therefrom. With this arrangement, portions of the ribbon upstream and downstream of the coating unit are exposed to coating vapors from the coating unit for different periods of time. A coating mixture includes tin containing precursors and a silicon containing precursor. The silicon containing precursor has the structural formula
       
where R 1  is a group which does not have an oxygen available to form a peroxide, R 2  is a functional group giving the silicon containing precursor the ability to be easily converted to silicon oxide coating, R 3  is a bridging group to provide for multiple silicon atoms and R 4  completes the bonding on the foundation silicon atom. An accelerant e.g. a phosphorus containing precursor may be used with the metal containing precursors to increase the deposition rate of the coating. The coating deposited on the glass has regions of continuously varying weight percent of silicon oxide and tin oxide as the distance from the glass-coating interface increases, with the surface of the coating farthest from the glass-coating interface being predominantly tin oxide. The regions within the coating provide the coating with different indices of refraction to eliminate iridescence resulting from increased thickness of the tin oxide at the outer coating surface and to provide the coated glass article with a neutral color. When phosphorus is used as the accelerant, the percent of crystallinity is reduced and approaches 0, thereby reducing or eliminating the coating haze.

Abstract: An ink jet apparatus applies a drive voltage to electrodes formed on portions of side walls made of piezoelectric ceramics and varies the internal volumes of grooves adjacent to the side walls using the action of a deformation produced by a piezoelectric thickness/slip effect of the piezoelectric ceramics. Thereby, ink stored inside the grooves is ejected. According to such an ink jet apparatus, a void ratio of the piezoelectric ceramic is 10% or less, and an average crystal grain diameter of the piezoelectric ceramics is 10µm or less. Further, a variation in a ratio d₁₅/S E44  of a piezoelectric constant d₁₅ of the piezoelectric ceramic to an elastic compliance S E44  thereof between the side walls falls within 4. A ratio H/W of a height H of each side wall to a width W thereof ranges from above 2 to below 9, and a ratio d₁₅/S E44  of a piezoelectric constant d₁₅ of the piezoelectric ceramic to an elastic compliance S E44  thereof is 10 or more. It is thus possible to provide an ink jet apparatus having excellent durability and high reliability.

Abstract: An input digital signal is recorded as inclined tracks on a magnetic tape by rotating heads. The full length (L) of the tape is nearly divided by four in the longitudinal direction. A leading portion (L / 4) of the beginning of the tape is a general data recording area and the remainder is a continuous data recording area (Fig. 9). General data and continuous data are recorded as SYNC blocks. The number of SYNC blocks for one track of the general data is the same as that of the continuous data. By dividing the SYNC blocks of one track, a basic unit of general data is formed. The basic unit is divided into sub-units. The data construction of the sub-unit is the same as that of audio data recorded in an audio data area of one track. A rate detecting circuit (43) determines rate information, representing the data rate of input data, which is supplied to a mechanism controller (45). The controller (45) controls a buffer memory (46), a frame segmenting circuit (48), and a tape head mechanism (20) in correspondence with the data rate information. For example, the number of rotations of a drum on which a rotating head is disposed and the tape travel speed are decreased in correspondence with the ratio for the case in which standard data is recorded. Thus, data at a lower data rate than that of standard data can be recorded on the tape with the same track format as that used when standard data is recorded.

Abstract: A double-cassette-type magnetic recording-reproduction apparatus wherein a cam gear allows the second over-stroke lever to shift in advancing and retracting manners and, following these movements, a mode lever and the second head mount are allowed to move to the first through third positions. When the mode lever is located at the first position, the first over-stroke lever is shifted to an operable position and the second head mount is blocked by the second idler lever from its advancing movement. When the mode lever is located at the second position, the shift-blocking state of the second head mount is released, and the first over-stroke lever is not allowed to shift. When the mode lever is located at the third position, the first over-stroke lever and the second head mount are allowed to shift to the operable positions. This construction makes it possible to reduce the number of driving means and cut the cost of production.

Abstract: A power steering system (10) for use in a vehicle includes a power steering pump (12) which is driven by an engine (13) of the vehicle. The output from the power steering pump (12) is connected to a power steering valve (22). The power steering valve (22) is connected with a power steering motor (24). When the engine (13) is turned off, that is, in a non-operating condition, and the power steering pump (12) is not being driven, the fluid pressure in motor cylinder chambers (40, 42) is prevented from falling below a predetermined pressure to keep seals (64, 66) in sealing engagement with the power steering motor 24. To keep the fluid pressure in the motor cylinder chambers (40, 42) from falling below a predetermined pressure, a one-way valve (70) blocks the flow of fluid from the power steering valve (22) back to the reservoir (16). A pressure relief valve (72) blocks the flow of fluid from the power steering valve (22) to the reservoir (16) when the fluid pressure in the motor cylinder chambers (40, 42) is equal to or less than the predetermined pressure required to urge seals (64, 66) into sealing engagement with the power steering motor 24.
