Title: Digital filter device
Inventor: NISHIGUCHI MASAYUKI
IPC: H03H17/04
Filed: 1987-08-20
Abstract: PURPOSE:To obtain a steep noise shaping characteristic by a simple circuit constitution, and also, to improve an S N ratio in a necessary band, by using an IIR (infinite impulse response) filter, as a filter for applying a noise shaping processing to a digital signal which has been brought to over-sampling. CONSTITUTION:In a noise shaping filter 20, a signal X(z) which has been supplied to an input terminal 21 is sent to a quantizer 23 through an adder 22 and requantized, and sent to an output terminal 24. By subtracting from an output of the quantizer 23 its input, what is called a quantizing error or a quantizing noise E(z) is formed, and this error or the noise E(z) is sent as a subtracting signal to the adder 22 through a circuit part consisting of an adder 26, predictors 27, 28 and an adder 29, and a noise shaping characteristic is obtained as a whole. Said circuit part consisting of the adder 26, the predictors 27, 28 and the adder 29 has a constitution of a kind of what is called IIR (infinite impulse response) filter having a a zero point and a pole in a transfer characteristic.

Title: Semiconductor laser
Inventor: HAMADA HIROYOSHI
IPC: H01S5/028
Filed: 1982-11-22
Abstract: PURPOSE:To enable high output oscillation and contrive to prolong the lifetime by coating a resonator end surface with SiC. CONSTITUTION:The first clad layer 3, an active layer 4, the second clad layer 5, and a cap layer 6 are laminated on one main surface of an N type GaAs substrate 1 by successive epitaxial growth. The photo resonator is formed of the first and second clad layers 3, 5 and the active layer 4. Protection film 7 composed of polycrystalline or amorphous SiC are formed on the surfaces of resonator end surfaces 1a and 1a. When SiC is thus used as the protection film 7 on the end surface, deterioration due to stress does not generate because of the approximation of coefficients of thermal expansion between SiC and GaAlAs series single crystal; and the thermal conductivity of SiC is high, therefore optical damages hardly generate.

Title: Method and device for highly efficiently controlling induction motor
Inventor: RIKIHISA KATSUTOSHI
IPC: H02P27/04
Filed: 1993-08-19
Abstract: PURPOSE:To improve the operating efficiency of an induction motor by switching an exciting current command value based on the result of judgment whether or not a torque current command is a certain value or less at least at a rotational speed above a certain value. CONSTITUTION:In an acceleration step, the speed fm of an induction motor 4 is smaller than a judgment value Kfm, and even when acceleration lasts for a certain time, a torque current command value I2r is larger than a judgment value K12 with a large torque required. Consequently, in a judging device 101, a common terminal (c) of the first changeover switches 104, 107 is connected to a terminal A. Accordingly, a vector control circuit 1 is normally actuated to control an inverter in order that the speed fm agrees with a speed command value fmr in good response. When the torque current command value I2r is decreased below the decision value I12, the judging device 101 switches the common terminal C to a terminal B. Then in a current command arithmetic device 13, the level I1r and the phase thetar of the supply current of the induction motor 4 are calculated from the torque current command value I2r of a speed controller 12 and from an exciting current command value IMr' of an exciting current command arithmetic device 106.

Title: Vertical pump
Inventor: ICHIKAWA HIDEAKI
IPC: F04D29/44
Filed: 1981-12-21
Abstract: PURPOSE:To prevent sand from being jammed in both stationary and rotating parts of a pump, by causing a setup between the inner wall of a casing and the inner surface of a shroud in front of an impeller of the pump to be interconnected with a little vertical step difference H. CONSTITUTION:When stopping operation of a multistage submersible pump, water being once pushed upward flows backward and sand contained in pumped water is put back in the suction port side. An inner wall 3b of a casing 3 and an inner surface 2d of a shroud 2c in front of an impeller 2 are interconnected with each other via a small clearance S but since there is a step difference H  between them, sand being dropped along the inner wall 3b of the casing 3 will surely drops on the inner surface 2d of the shroud 2c in front of the impeller 2 across the clearance S. Therefore, sand jamming trouble can be prevented more certainly.

Title: Pattern classification device
Inventor: WAKIZAKA SHINJI
IPC: G06G7/60
Filed: 1992-07-31
Abstract: PURPOSE:To obtain a pattern classification device with high classification ability by providing a rotary processing means which rotates the arranging order of plural input signals and impresses a signal compensating positioning on the plural input terminals of a network. CONSTITUTION:The rotary processing part 1, a statistics calculation processing part 2, neural networks 3 and 4 and a data selector part 5 are provided. The signal compensating positioning by rotating the arranging order of the plural input signals is impressed on the input terminals of the network. Even if the pattern of the input signal is rotated such as the temperature distribution signal of a blust furnace, for example, in the rotary processing part 1, the position of the rotary direction is arranged so that it coincides with the rotary direction position of a reference pattern (pattern for learning), and the signal is impressed on the network. Thus, the rotary position of the input signal pattern does not affect the network. Consequently, the pattern classification ability of the network considerably improves.

Title: Taking-up device for belt
Inventor: MOMOSE HIROTSUNE
IPC: B65H75/36
Filed: 1989-08-10
Abstract: PURPOSE:To obtain the belt taking-up device having small installation space with the simple structure by fixing the edge part of a belt having the composite structure of a strip-shaped member and a memory member on which a swirl shape is memorized, onto a shaft which is supported in turnable manners onto a supporting member. CONSTITUTION:A belt 3 is heated by the environment in the state Where the belt 3 is driven out from a casing 1. When the temperature of a memory member 5 composed with the belt 3 becomes over 70 deg.C because of heating, the memory member 5 restores the memory shape of swirl form. At this time, a strip- shaped member 4, i.e., the belt 3 is deformed to a swirl shape, accompanied with the shape restoration of the memory member 5. Since the edge part 3a of the belt 3 is fixed onto a shaft 2, the shaft 2 is turned by the deformation of the belt 3, and at the same time, the belt 3 is wound onto the shaft 2. Therefore, the belt 3 can be taken up onto the shaft 2.
