Title: Bar code-scanner
Inventor: BURAIAN JIEI BEIREI
IPC: G06K7/015
Filed: 1989-09-21
Abstract: PURPOSE: To provide suitable resolution by converging one part of image of a bar code tag on a photodetecting means by forming the image of the photodetecting means on a second surface across the bar code tag and forming the image of the bar code tag across a first surface. CONSTITUTION: A lens 21 forms an image 25a of a photodetector array 25. The array 25 specifies an operating range 27 of a bar code reader into a plane across a bar code tag 23 to be read. A main plane A of the lens, a plane B of the detector array and an operating range plane C have a common crossover line X so that a sheimpflug's condition can be constituted. With this constitution, the lens 21 forms the image of the bar code tag 23 on the detector array 25. Namely, when the bar code tag 23 is positioned inside the operating range 27, the horizontal intercepts of an image 23a of the bar code are almost converged on the elements of the detector array 25. Thus, the proper resolution is provided.

Title: Automatic balance device for motor
Inventor: OSAWA HARUSHIGE
IPC: H02K21/22
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To restrict rotational deviation during a low-speed rotation and to reduce noise. SOLUTION: A housing portion 25, consisting of a ring-shaped space concentric with a shaft 9 as a component of a motor, a rotor hub, turntable or the like is formed, a plurality of steel balls 26 are housed in the housing 25 as a balance body; if the rotating speed of a motor is less than a predetermined speed, then each steel ball 26 is constrained by constraining means 27 in the housing 25, and constrained state of each steel ball by the constraining means 27 is released after reaching the predetermined speed. At this time, the constraining means 27 comprises a sleeve 28, a supporting body 29 and a weight 31. If a centrifugal force to the weight 31 is small, then the tilting of the weight 31 by an elastic force of the supporting body 29 is disturbed. If the centrifugal force to the weight 31 increases, then the weight 31 is tilted in an outer peripheral direction.  An end portion of the supporting body 29 is separated from each steel ball, each steel ball 26 is released, and each steel ball 26 becomes movable inside the housing 25.

Title: Raising structure for platform
Inventor: NAKAYAMA TAKESHI
IPC: E01C23/10
Filed: 1993-09-06
Abstract: PURPOSE:To perform simple and rapid raising of a platform surface by a method wherein the height of a plate is regulated by using bolt legs and an empty area partitioned by the bolt legs is filled with a rigid urethane foam raw material. CONSTITUTION:A plate 1 in which a male screw member 4 is fitted is arranged on an existing platform 10. A bolt leg 2 made of plastic is joined in a screwed-in state with the female screw member 4. A driver is inserted in a groove 5 formed in the head part of the bolt leg 2 and by rotating the driver, the height of a plate 1 is regulated. When the head part of the bolt leg 2 is protruded from the plate 1, the protrusion part is cut. An empty area formed between the bolt legs 2 is filled with a rigid urethane raw material to foam the raw material. Since the rigid urethane foam 3 itself serves for an adhesive, displacement of the plate 1 owing to vibration is prevented from occurring.

Title: Device for photoelectric length measurement or angle measurement
Inventor: BUARUTAA FUUBAA
IPC: G01D5/38
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a photoelectric length or angle measuring apparatus in which the measurements are insensitive to the local fluctuation in the measuring graduations being scanned and relatively insensitive to the fluctuation of scanning interval by deflecting at least a part of partial beam flux passed through a partial scanning measurement field of view in the direction of common partial region of a dial. SOLUTION: A light passes, at first, through a scanning plate 35 and impinges on a dial 45 where it is reflected and diffracted to pass through the scanning plate 35. After passing through the scanning plate 35 twice, the luminous flux arrives at a detection element which detects a modulation signal dependent on the position in case of relative movement. Deflection means 3d5, 3e5, 3f5 performing direction selectivity action on the rear side 37 of a scanning plate 35 deflects the light to a common region 4b5 of measuring graduations 4a5 being scanned by the entire incident luminous flux from partial scanning measuring fields of view 3a5, 3b5, 3c5 producing phase shifted signal components thus guaranteeing the single field scanning.  The phase shifted signal components are separated spatially by diffraction at the second time passage of luminous flux through the scanning plate 35 and detected on the focal plane of a condenser optical system.

Title: Receipts and disbursements data processor
Inventor: SANADA TAIJI
IPC: G06Q40/02
Filed: 1992-09-16
Abstract: PURPOSE:To provide a receipts and disbursements data processor capable of automating the totalizing processing of receipts and disbursements data and reducing the generation of miscalculation. CONSTITUTION:A totalizing device 2 receives money-sorted receipts and disbursements data transmitted at every transaction end on a window from plural teller's machines 1 and totalizes the number of sheets and the amount of money at every kind of money in real time processing as the totalized data of every kind of machine and every kind of teller. After ending daily business, each teller carries cash and negotiable securities such as bills and checks to be stored on hand to the device 2, which reads out the totalized data of each teller and counts up cash by a cash counter. Thus, only the individual data are inputted from the input part of the device 2. Then, the device 2 collates the totalized data with the totalized amount of the cash and the negotiable securities such as bills and checks and displays the collated result. Since it is unnecessary for each teller to input totalized amounts, the handling time can be saved and the generation of miscalculation can be reduced.

IPC: H04N5/93
Filed: 1991-09-26
Abstract: PURPOSE:To improve reproducing performance by switching between an FM- demodulated reproducing video signal and a vertical blanking signal generated in a recording system based on a signal indicating a PCM audio signal area and using the PCM audio signal area signal of the reproducing video signal after the FM demodulation as the blanking signal generated in the recording system. CONSTITUTION:A PCM audio (P) signal is inserted in a blanking (B) period of the video signal by switches 9 and 10, and a VB data generator 25 generates a VB signal of the video signal at the time of recording and reproducing. A PC area signal generator 29 generates the PCM area signal indicating the P signal area within the reproducing signal and drives a switch circuit 30 to switch between the VB signal of the generator 25 and the output of an FM demodulator 19. Accordingly, the signal in the P signal area of the FM- demodulated reproducing video signal is used as the VB signal in the recording system and the operation of a second synchronization separation circuit 22 and a clamping circuit 20 is ensured. Thus, sagging can be reduced and an excellent reproducing video signal can be obtained.

Title: Device for controlling drive of brushless motor and electric appliance using it
Inventor: TAKADA MASAYUKI
IPC: H02P6/08
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the harmonic components in torque and ripple torque changing rates even at the time of rectangular wave conduction by turning on switching elements which are conducted to a plurality of phases of motor driving coils in a prescribed direction and prescribed order beyond a specific electrical angle from the zero-crossing point of an induced voltage. SOLUTION: The signal of a position detecting circuit 2 changes to 'H' from 'L' after, for example, a U-phase induced voltage changes to an electrical angle of 35 deg. from the zerocrossing point when the voltage changes to positive from negative. A drive circuit 5 detects the signal and a switching element turning-on means 5a turns on a switching element 3au . After the electrical angle reaches 60 deg., the signal changes to 'L' from 'H' and, at the same time, a switching element 3bv is turned off and another switching element 3 is turned on. When the electrical angle reaches 120 deg. thereafter, the signal changes to 'H' from 'L' and, at the same time, the switching element 3au is turned off and a switching element 3av is turned on.  Since the U-phase induced voltage component is low, the circulating period of the current flowing through a diode 7au becomes longer and the dropping of the sum of the u-phase circulating current flowing through a drive coil 4 and a V-phase transient build-up current becomes smaller.
