Title: Pole detecting circuit and driver for three-phase brushless synchronous motor employing it
Inventor: TAKAGI NOBUKAZU
IPC: H02P6/18
Filed: 1993-06-22
Abstract: PURPOSE:To prevent step out by producing a pole position signal having phase shift of 30 deg. from the combination of output waveforms from two out of three sets of differential amplifier circuits for detecting the differential terminal voltage of armature winding from a counter electromotive force having phase shifted by a primary low-pass filter. CONSTITUTION:Counter electromotive forces Va, Vb having 90 deg. phase lag, from which noise components are removed by means of a primary low-pass filter 11a, are amplified by amplifiers 14a, 14b and then the voltage Da between terminals is determined by a differential amplifier 16a. The voltage Da is outputted with 90 deg. phase lag behind the waveform Vab of counter electromotive forces to a comparator 13a where it is compared with a voltage Db between terminals. The comparator 13a outputs a pulse of 180 deg. width having 60 deg. phase lag behind the zero-cross point of the waveform Vab. In other words, a pole position signal Pa is generated. Similarly, pole positron signals Pb, Pc are generated from comparators 13b, 13c. The pole position signals Pa, Pb, Pc have 120 deg. phase lag.

Title: Device and method for modulation, device and method for demodulation and providing medium
Inventor: NAKAGAWA TOSHIYUKI
IPC: H04L27/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To record and to reproduce at high linear density. SOLUTION: A DSV control bit decision/insertion part 11 inserts a DSV control bit for DSV control in an inputted data sequence and outputs it to a modulation part 12. The modulation part 12 converts the data of two bit basic data length into a variable length code of three bit basic code length and outputs them to a non return to zero inverted(NRZI) part 13 in accordance with a conversion table. A conversion table which the modulation part 12 possesses has a replacement code for restricting continuation of a minimum run below the specified number of times and a replacement code for protecting a run length restriction, and moreover, a conversion rule which has a remainder after the number of '1' in an element of the data sequence is divided, by 2, and the remainder after the number of '1' in an element of a code word sequence is divided by 2 agree with each other as 1 or 0.

Title: Current source circuit
Inventor: HASHIMOTO HIDEYA
IPC: H03F3/343
Filed: 1987-06-17
Abstract: PURPOSE:To ensure a high-speed switching action and at the same time to decrease the number of elements of a current source circuit, by switching the base-emitter junction of a 4th transistor between the reverse or forward bias via the control voltage, thereby switching the inactive and active states to execute a fast switching operation. CONSTITUTION:A current source circuit is active and inactive when the base- emitter junction of a 4th transistor TR7 is biased reverse and forward respectively by the control voltage. The voltage applied to the base-emitter junction of the TR7 in a forward bias mode is kept under VBE (inter-base-emitter forward voltage). Thus the TR 7 is not saturated and switched at high speed. In addition, the value of a current source 12 has no relation with the value of the control voltage which is used to turn off the TR 7. Thus it is not required to connect a base resistance to both TRs 7 and 17 when plural current source circuits are controlled by a single control voltage generating circuit. Then the number of elements can be decreased for a current source circuit.

Filed: 1989-06-15
Abstract: PURPOSE:To offer the compact zoom lens system which has various aberrations compensated sufficiently from the wide-angle end to the telephoto end regardless of the high variable power rate and is extremely short in the overall length by using only lenses with negative refracting power for a lens group which has negative refracting power and is closest to the image side, and further using at least one distributed refractive index type lens in the lens group. CONSTITUTION:The zoom lens whose variable power ratio is 3 consists of a 1st lens group I with positive refracting power, a 2nd lens group II with positive refracting power, and a 3rd lens group III with negative refracting power. Further, the 3rd lens group consists of three lenses having negative refracting power so as to shorten the overall length of the lens system, and the distributed refractive index type lens having negative refracting power is as the lens which is closest to the object side in the lens group. Thus, the distributed refractive index type lens whose medium has negative refracting power is used in the 3rd negative lens group to decrease the curvature rate of the lens surface and prevent positive distortion from being generated, and negative distortion is generated by the medium to correct the distortion.

IPC: G06F3/0338
Filed: 1990-06-07
Abstract: PURPOSE:To attain the input of movement of a three-dimentional space with a planar movement of an input device by interpreting the planar movement as a three-dimensional movement and sending this movement to a connected computer as a signal. CONSTITUTION:A mouse serving as a conventional input device 2 is moved to the two-dimensional coordinates (X2, Y2) from the present two-dimensional coordinates (X1, Y1). At the same time, a signal is sent to a computer 3 from an input device 1 in the direction Y for example. Under such conditions, the mouse 2 is moved over an XY plane in regard of the computer 3 and the signal sent from the mouse 2 is turned into a three-dimensional vector (X1 - X2, Y1 - Y2, O). In other words, a planar movement is interpreted as a three-dimensional movement and sent to the connected computer 3 as a signal. Thus the input of movement is attained for a three-dimensional space with a planar movement produced by a single input device.

Title: Motor fan
Inventor: YAMAURA IZUMI
IPC: F04D25/08
Filed: 1983-08-18
Abstract: PURPOSE:To improve the performance of a motor fan by a method wherein a wavy protruded and recessed surface is provided on the lower surface of an air guide to prevent vortex and separation of air stream and guide the air stream smoothly into a volute section. CONSTITUTION:The lower surface 5e of an air guide, constituting the volute section 5a of the air guide 5, is provided with the wavy recessed and protruded surface 5h. According to this constitution, when the air stream, having much dynamic pressure component from a centrifugal impeller 4 and a high air speed, is flowed along the wavy recessed and protruded surface 5h at the entrance, a vacuum is generated at the recessed parts and separation, generated generally in a fluid flowing along a flat surface, is prevented by the attracting effect of the surface having vacuum, therefore, the air stream may be guided smoothly into the volute section 5a. On the contrary, the protruded part introduces an effect to facilitate generation of vacuum in the recessed part. As a result, the vortex, generated generally at the entrance of the volute section, is hardly generated, the vortex and the separation of the air stream may be prevented sufficiently and the performance of the motor fan may be improved.
