Title: Tracking servo method
Inventor: SUZUKI HARUYUKI
IPC: G11B7/095
Filed: 1989-12-15
Abstract: PURPOSE:To obtain a specified tracking error signal by normalizing the tracking error signal by the signal of the difference between the average value of two reproduction signals and the reproduction signal from the sample flag of an approximate track center. CONSTITUTION:The reproduction signal from a photoelectric converter 11 is amplified 12 and is inputted to sample-hold circuits 13 to 15 from which the reproduction signals (a), (b), (c) corresponding to the tracking sample flags A, B and the clock sample flag C are obtd. A subtractor 16 yields the tracking error signal by obtaining the difference between the signals (a) and (b). The signals (a) and (b) are added by an adder 17. The added value is halved by an amplifier 18 and a subtractor 19 computes the difference between the output signal of the amplifier 18 and the signal (c). This differential signal is compared with a constant value const by a comparator 20. The output signal of the comparator 20 is integrated by an integrator 21 and the gain of a variable gain amplifier 12 is controlled by the output of the integrator 21. The constant tracking error signal is, therefore, obtd. from the subtractor 16.

Title: Sodium bicarbonate particle having treated surface and formed formulation containing the same
Inventor: YOROZU HIDENORI
IPC: A61K8/00
Filed: 1989-12-15
Abstract: PURPOSE:To obtain sodium bicarbonate particles, having treated surfaces and capable of forming tablet or granule, etc., and simultaneously providing formed formulations excellent in stability without using other binders by coating the surfaces of the sodium bicarbonate particles with Na2CO3 or a double salt thereof. CONSTITUTION:About >=50% surfaces of sodium bicarbonate particles having >=30mum average particle diameter are normally coated with Na2CO3 or a double salt thereof. In this case, the thickness of the Na2CO3 on the surfaces of the sodium bicarbonate particles is especially preferably 0.1 to 5mum. The surfaces of the sodium bicarbonate particles are coated by, e.g. heating the sodium bicarbonate particles at >=70 deg.C. For example, the surfaces of the sodium bicarbonate particles having 200mum average particle diameter may be converted into the sodium carbonate having about 1mum thickness by heating the surfaces at about 100 deg.C temperature for 30min. The resultant sodium bicarbonate particles with the treated surfaces have excellent binding force and the resultant formed formulation is simultaneously excellent in preservation stability.

The unit cost performance of a CPU and the unit cost performance of input and output are considered and the rough estimate value of the processing time is obtained and returned to the processing request source 3. This approximation value is larger than the real processing time and accuracy is improved by correcting the approximation value by a really selected number of tuples when processing is executed. Thus, the processing time can be predicted with the small number of the overhead.

Filed: 1987-12-23
Abstract: PURPOSE:To reduce the number of parts and improve the assembling operability by constructing such that when a hydraulic pressure in a first cylinder exceeds a specified value, a spindle is advanced toward a rotor and an abutment between an adjusting nut and a piston is kept. CONSTITUTION:When brake oil is supplied in a first cylinder chamber 1a and the pressure of the brake oil is a specified value or more, a hydraulic pressure balance applied to a spindle 4 effects to move the spindle 4 leftward. Even if a gap between a pad 36 and a rotor 37 is a specified width or more, an abutment between a flange part 3a of an adjusting nut 3 and a bottom of a piston 2 is kept, so that the gap is not adjusted to prevent an excessive adjustment. It is therefore possible to reduce the number of parts, to facilitate the processing of the parts, and to facilitate the assembling since each part can be installed from the insertion side of the piston 2.
