Title: Controlling circuit for stopping of dc motor
Inventor: SAKAI MASAAKI
IPC: C07C49/792
Filed: 1980-06-06
Abstract: PURPOSE: To forcibly stop a DC motor in a purely electrical manner and make it maintain said stopping point, by making the motor generate a reverse damping torque when the motor stopping instruction is given, and controlling the motor so that the rotation thereof is stopped at a point of time when the motor voltage is zero.  
     CONSTITUTION: When the motor stopping instruction is given, a signal SP becomes high in level, so that a switching circuit 9 is changed over to the state opposite to that shown in the figure. Moreover, the output signal FG of a frequency generator 5 is amplified in an amplifier 8 and fed to a drive circuit 6, as a signal DS, through the switching circuit 9. Because said signal DS is a sine-wave AC signal of average level OV, transistors 61 and 62 are turned on every positive and negative half-cycle periods of the signal DS respectively, and a voltage ES is applied to a motor 1. The stopping position of the motor 1 is one of the points P 1 , P 2 ..., in the zero cross points of the voltage ES, where the forward torque decreases as the voltage ES approaches the zero cross points during the positive voltage period while the reverse torque increases as the voltage ES becomes more distant from the zero cross points during the negative voltage.

Title: Washing machine
IPC: H02P7/00
Filed: 1992-03-31
Abstract: PURPOSE:To properly detect the cloth quality of a wash put in a spin basket by lowering drive voltage applicable to a brushless DC motor to a zero level for the free running thereof, when the motor reaches a constant speed after the placement of the wash, and detecting a cloth volume from a motor speed reduction rate. CONSTITUTION:When a start switch is pressed, flat clutch discs are engaged to each other and a spin basket is thereby caused to rotate, together with a pulsator, on the operation of a brushless DC motor 5. When the angular velocity of the motor 5 reaches the predetermined value, upper arm transistors U1, V1 and W1, and lower arm transistors U2, V2 and W2 of an inverter circuit 17 are all turned off. The supply of drive voltage is thereby stopped and the motor 5 is caused to rotate on inertia. Concurrently, a software timer in a microcomputer 26 is reset and caused to start a counting process. When the angular velocity of the running motor 5 reaches a predetermined value, a cloth volume size is determined from a data table in the memory of the microcomputer 26 on the basis of the duration of a counted time.

Title: Line analyzer in electron beam scanning type analyzers
Inventor: TANAKA YASUNOBU
IPC: H01J37/256
Filed: 1982-05-07
Abstract: PURPOSE:To eliminate a shear lying between a picture analytic image and a line analytic profile, by adding a correction signal to an x-directional scanning signal of a CRT in time of being switched to a state of line analyzingness and thereby dislocating a starting point of x-directional scanning in response to a lag in the rise of an x-directional deflecting signal. CONSTITUTION:The output of a secondary electron detector 1 is impressed on a CRT2 for display use as a luminance signal while the output of a scanning signal generating circuit 3 is transmitted to a scanning circuit 4 where scanning the surface of a sample S takes place. When it is switched to a line analysis, the output of a signal processing circuit 9 is added to a y-directional scanning signal held so far, at an adding circuit 6A and transmitted to a scanning circuit 5. An adding circuit 6B adds the output of an operation circuit 10 to an x-directional scanning signal while the circuit 10 calculates the shear value on the basis of data transmitted from a time constant setter 12 of an x-directional speed setter 12 and the signal processing circuit 9, and gives the circuit 6B a correction signal. For this reason, at the CRT2, the x-directional scanning starts from a position being more dislocated than in case of a surface analysis, so that a shear in profiles can be eliminated.

Title: Composition for forming intra-ocular lens
Inventor: YOSHIDA KUNIHISA
IPC: A61F2/16
Filed: 1989-03-29
Abstract: PURPOSE:To facilitate the intra-ocular injection of the liquid compsn. contg. a photopolymerizable monomer and a photoinitiator and to cure the compsn. in a short period of time after the injection by polymerizing the compsn. in the eye. CONSTITUTION:The liquid compsn. which contains the photopolymerizable monomer and the photoinitiator and has a photosetting property is used as the injection material to be injected directly into the crystalline capsule after the crystalline lens is substantially removed in the state of allowing the crystalline lens to remain or to be injected into the balloon body inserted into the crystalline capsule. This compsn. is irradiated with prescribed light and is cured in a short period of time within the eye, by which the intra-ocular lens is formed. The direct injection of the photopolymerizable monomer into the crystalline capsule is possible as the bioadaptability is imparted in terms of toxicity and resilience, etc., in the case of adopting a silicone monomer for the photopolymerizable monomer. The injection material does not come into direct contact with the inside of the crystalline capsule in the case of using the compsn. by injecting the same into the balloon housed in the crystalline capsule and, therefore, the free selection of the photopolymerizable monomer is possible.

Filed: 1995-04-03
Abstract: PURPOSE: To improve the character recognition precision by providing a specific binarization processing means, a feature extracting means, a character characteristic quality judging means, and a 'threshold' varying and setting means. CONSTITUTION: Gray image data obtained by optically scanning a document to be read through an image scanner are processed by primary binarization based upon a specific 'threshold' (S1) and on the basis of the binarized image data, a ground of document areas is extracted (S2). In the extracted document areas, feature quantities for judging the characteristic quality of the document character patterns are found (S4) and on the basis of the features, the characteristics and quality of the character patterns in the document areas are judged (S5). On the basis of the judging results, a 'threshold value' for secondary binarization is selected (S6), the secondary binarization of the gray image data is generated, and the result replaces the primary binarized image data (S7).  And, a binarized image memory stores the binarized image data for which the optimum 'threshold values' are set by the separated and divided document areas.

Filed: 1986-04-04
Abstract: PURPOSE:To miniaturize a detector together with its original device by leading the light emitted from an electron-light coversion face to a one-dimensional light detector via an optical fiber'. CONSTITUTION:Those ions passing through a multi-slit plate 3 are incident on a multi-channel plate 4 located further behind therefrom, and converted to secondary electrons before being amplified. A phosphor film 5a is applied to the upper face of a fixed plate 5 located further behind the plate 4. And the secondary electrons emitted from the plate 4 are incident on the phosphor film 5a to be converted to the light. the euds on one side of many streaks of optical fiber 6 are disposed at the interval of slits on the lower face of the phosphor film 5a and the ends on the other side of the fibers 6 are formed together in an optical plate 7. And, since the width of a linear sensor 9 acting as a one-dimensional detector is smaller than the width of the plate 7, any shrunk image is further reduced in its size by using a lens 8 to be formed in an image on the detecting surface of the sensor 9. Thus, the detector can be minaturized.
