Title: Controller for induction motor
Inventor: SUGIYAMA SHOJI
IPC: H02P27/06
Filed: 1992-01-16
Abstract: PURPOSE:To eliminate the distortion in input current and saturation of motor voltage by reducing a primary current by compensating a slide frequency when the motor voltage is saturated due to reduction in battery voltage and the primary current is distorted. CONSTITUTION:A battery voltage detector (BD) 10 detects the voltage of a battery 1 and then outputs it to a control circuit 4. The control circuit 4 obtains a target torque of a motor 3 from detection signals of sensors 5a-7a and at the same time obtains an actual rotary speed of the motor 3 from the detection signal of a rotary sensor 8. Then, a slip frequency is indexed based on the obtained target torque and the actual rotary speed. Also, a detection signal is input to BD 10 and then the voltage of the battery 1 is obtained. When the voltage of the battery 1 exceeds a reference voltage, the voltage of the battery 1 is obtained. When the voltage of the battery 1 is lower than the reference voltage, it is judged that the motor voltage of the motor 3 is in saturation. Then, compensation is made so that the slide frequency is reduced. Namely, the target torque is reduced and a command current is reduced, thus preventing the input current from being distorted.

Abstract: PURPOSE:To prevent the occurrence of an error by associating the switching point of a receiver with the switching point of data. CONSTITUTION:Data signals of the same kind inputted to receivers 1 and 2 do not have equal signal levels all the time, so received signals with different levels are outputted.

Title: Discrimination processing system of character pattern
Inventor: UMEDA MICHIO
IPC: G06K9/62
Filed: 1980-01-23
Abstract: PURPOSE:To enable the extremely accurate discrimination of character patterns to be performed with less memory capacity by extracting the partial patterns effective for discrimination by using the standard patterns consisting of only the characteristic information of each character pattern. CONSTITUTION:Two or more candidate character categories selected by a classifying circuit 5 are beforehand stored in a candidate character storage register 8. Next, the two character categories are fetched from the register 8 and the feature list of the corresponding character categories are fetched from a standard pattern table 9. Based on this information, the character patterns are made by character pattern making circuits 10, 11. The partial patterns which differ largely with respect to the respective partial patterns of these two character patterns are extracted and are stored respectively in partial pattern storage registers 16, 17. A collating circuit 18 superposes the unknown input character pattern stored in the memory circuit 4 and the patterns of the registers 16, 17, and decides to which character category said pattern is approximate. Next, the register 8 is accessed by a discrimination decision circuit 19, whereby the result 7 of discrimination is obtained.

Title: Lubricating oil feeding system for rotary engine equipped with supercharger
Inventor: TSUBOUCHI HARUYOSHI
IPC: F02B53/08
Filed: 1980-01-25
Abstract: PURPOSE: To enable to feed a proper amount of lubricating oil to a rotary engine efficiently, by providing a mixer for spraying lubricating oil into the intake manifold at a downstream portion of a compressor.  
     CONSTITUTION: When compressed air-fuel mixture is supplied from a compressor 10 of a supercharger into an intake manifold 5, the mixture flow is accelerated at a venturi 18 of a mixer 15 disposed at the central portion of the intake manifold 5 since the mixture flow is restricted by the venturi 18. Resultantly, negative pressure is developed at an orifice 17, so that lubricating oil pressurized by an oil pump 7 is atomized. Lubricating oil thus atomized is distributed uniformly into the mixture flow and supplied to a rotary engine 8 without sticking to the wall surface of the intake manifold 5. With such an arrangement, it is enabled to recover most of the lubricating oil to the oil pump 7 and therefore to minimize the consumption of lubricating oil.

Title: Dielectric filter
Inventor: ARAKAWA JUJI
IPC: H01P1/208
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the effects of the shape of a connection window part on spurious characteristic of a filter high-order mode and then to adopt an arbitrary shape by using TE-mode resonators which are not point-symmetrical mode resonators and joining the resonators together through an electrode material having a coupling window part or a ceramic substrate provided with an electrode on the surface. SOLUTION: Two resonators 1a and 1b which are not point-symmetrical but TE10 -mode resonators 1a and 1b are coupled in series across the electrode material 2. Then the shape of the coupling window part 21a of the electrode material 2 exerts no effects on spurious characteristics of a high-order mode and a point-symmetrical shape is therefore not needed to obtain an arbitrary shape, without the need for shape precision on condition that the quantity of coupling between the resonators 1a and 1b is unchanged. Further, there is no restriction on the shape of the coupling window 21a, so even where the coupling window part 21a is made large by cutting the electrode material 2, deterioration in spurious characteristic is eliminated, and the coupling quantity between the resonators 1a and 1b can be adjusted easily.

Abstract: PURPOSE:To measure the arranging interval between lugs accurately and precisely in a short time by providing a driving device for moving a base bodies at a specified speed in a specified direction, rollers, a displacement sensor, a pulse generating part and a control part. CONSTITUTION:A motor 26 is driven, and a drum 22a is rotated. Thus a track belt 10 is turned. When a roller 33 is in contact with an inner surface 11a of a base body 11 of the belt 10, the detected signal from a displacement sensor 34 is not inputted into a control part 50. When a roller 32 comes into contact with a lug 12-1, the roller 32 is displaced with respect to the inner surface 11a. When a specified amount is exceeded, the detected signal from the sensor 34 is inputted into a control part 50. The roller 32 is slid on the lug 12-1. When the displacement amount becomes less than the specified amount, the detected signal is stopped, and roller 32 comes into contact with a reference surface. When the belt is turned and the roller 32 comes into contact with a lug 12-2, the same operation as before is performed. The control part 50 computes the arranging interval of the lugs based on the counted number of a pulse counter 43 from the previous input time of the detected signal to the input time at this time and a preset pulse period.

Abstract: PURPOSE:To carry out effective cleaning by constituting the apparatus with a casing having a slender-shaped cleaning surface, a suction nozzle provided inside the casing, jet nozzles surrounding the suction nozzle and a flexible enclosing member surrounding the cleaning surface. CONSTITUTION:The cleaning heads 10, 11 are connected by ''U''-shape arm 12. Then the apparatus is caused to be moved from the side direction under such condition that upper and lower molds are opened. After this process, the cleaning surface part of the heat is caused to approach onto upper and lower mold surfaces and to vacuum-suction while it is made to move back and forth. At the same time, it is caused to carry out cleaning with high-pressure air blowout. At that time, resin flocks 14 attaching to a mold parting surface is blown off by establishing high- pressure air pipe's air jet holes 5 at an angle leaning toward the center. The blown- off resin flocks are sucked in through a central vacuum suction nozzle and discharged outside, thus preventing the scattering of flocks, etc.
