Title: Pattern reader
Inventor: OSAKI MORIHIDE
IPC: G01N21/956
Filed: 1988-11-02
Abstract: PURPOSE:To easily change the resolution of pattern reading by changing sampling frequency for the digitalization of an image signal in accordance with the resolution. CONSTITUTION:A CCD line sensor 3 reads out a wiring pattern 2 every movement of a printed-wiring substrate 1 by a fixed distance in an arrow direction. A line sensor driver 4 drives the sensor 3 so as to read out image data within charge accumulation time corresponding to a shift pulse with a fixed frequency. The driver 4 transfers the read pattern data to a binarizing circuit 5. The circuit 5 binarizes the image signal of the sensor 3 applied through the driver 4 in accordance with a sampling pulse applied from a frequency modulating circuit 8. The circuit 8 applies the sampling pulse with the frequency corresponding to the pattern reading resolution previously set up in a control part 11 to the circuit 5.

Title: X-ray ct apparatus
Inventor: TANAKA KOJI
IPC: A61B6/08
Filed: 1992-09-21
Abstract: PURPOSE:To enable the positioning of a slicing surface with ease by one photographing by allowing the learning of points of staring and ending the photographing of a part to be inspected with a projector in the photographing of a fluoroscopic image. CONSTITUTION:The photographing of a CR image is performed with a top board 20 of a bed 20 moving in the direction of being pulled from a gantry 20. Hence, the placement of a projector 30 is opposite to the bed 20. A termination oriented projection position is set so that a distance between the projection position of the projector in the gantry 10 and the projection position of a projector 30 for termination of the CR image coincides with a size of a part to be inspected in the direction of feeding the top board. In the photographing of the CR image, when a projection switch for the CR image is depressed in the setting of a subject, the subject is exposed to light projected both from the projector in the gantry 10 and the CR image termination projector 30 to allow the checking of both ends of a range covering the CR image on the specimen. This enables the learning of respective positions of the starting and ending ends in the direction of the bed in the CR image to be photographed on the specimen simultaneously thereby facilitating the determination of the position of starting the photographing.

Title: Production of carbon cluster
Inventor: NAKAO NOBORU
IPC: C01B31/02
Filed: 1992-10-16
Abstract: PURPOSE:To sharply improve the yield and to dope with different elements other than carbon when synthesizing a carbon cluster by making pressure in an atmosphere at the specified value or more, adding metal elements or halogen elements to graphite electrodes and adding an dopant as gas phase to the atmosphere. CONSTITUTION:When a carbon cluster (e.g. C60, C70) is synthesized by the discharge between graphite electrodes, helium is used as its atmosphere and pressure in the atmosphere is made 1 atmosphere or higher as absolute pressure, causing the carbon molecules formed by the reaction to be rapidly cooled by gaseous helium, permitting the formation yield of the carbon cluster to be improved. And metal elements or halogen elements or both of them as different elements from carbon are incorporated in the graphite electrodes, allowing the carbon cluster to be doped with these elements. And a dopant added to the atmosphere is a metal element or halogen element and at that time, their simple substances or compounds are vaporized and introduced into a discharge zone.

Title: Memory access controller
Inventor: YAMADA IKUO
IPC: G06F15/177
Filed: 1986-11-21
Abstract: PURPOSE:To simplify an error processing at the time of generating a trouble by detecting the error of the contents of a reading register and replacing a request command by NOP. CONSTITUTION:An error detection circuit 700 monitors the output of the buffer reading registers 101-105 to detect the error, detects the request command which is not permitted and checks the contradiction of the command. Then, when there are the errors in the registers 101-105 selected by a selection means 200, a command replacement instruction 800 is outputted to a command replacement circuit 600. The circuit 600 changes all of the request commands of the outputs of the selection means 200 to '0' according to the replacement instruction 800 from the detection circuit 700 and outputs as the non-operation command of a request processing part 300. Thereby, at the time of the trouble, the request command is replaced by the non-operation command to simplify an error processing.
Patent JP-S61150078-A (JP)
Title: Pattern reader by optical beam scanning
Inventor: KANAI NOBUO
IPC: G06K7/10
Filed: 1984-12-24
Abstract: PURPOSE:To prevent outer light from making incident on a photodetecting element and to give a low bright light source having a wide wavelength distribution by limiting a range where a photodetecting optical system watches a pattern face. CONSTITUTION:A scanning optical beam F scans a bar code face from a point B to a point B' with the aid of the rotation of a rotary multiphase mirror 4. Reflected light X from the bar code face 5 is so set that light beams in the range AA' can make incident on the photodetecting element 8 through a lens 6. Namely the pthotodetecting optical system composed of the photodetecting element 8, the lens 6, a mirror 7 and the rotary multiphase mirror 4 watches the range AA' including the bar code face irradiating point of the optical beam F. The reason why the photodetecting optical system does not narrow the range AA' where it watches the bar code face up to the size of the bar code face irradiating point of the optical beam F is that a shift occurs between the optical beam irradiating point and the range AA' during scanning due to sight differences on the bar code face of a scan optical system and the photodetecting optical system. Accordingly a space is given to the range AA' so that the point where the photodetecting optical system watches hardly deviates from the irradiating point of the optical beam due to the shift. As a result, the influence of outer light can be reduced.

With this constitution, any fear of the antislip member 50 being broken down is eliminated and thus any possible slip-out motion of the piston 34 is surely obviable in this way.

Abstract: PURPOSE:To make it possible to reduce a defect owing to a dielectric breakdown by using a thyrister as switching elements to compose an ageing circuit so as to make the pulse width applied to a picture element as narrow as possible in the scope to obtain the lighting necessary for ageing. CONSTITUTION:The first field in which a picture element ELA emits light by applying a positive electrode type voltage to a transparent electrode, and the second field in which a picture element ELB emits light by applying a positive electrode type voltage to a transparent electrode are provided. Furthermore, the third field in which the picture element ELA emits light by applying a negative electrode type voltage, and the fourth field in which the picture element ELB emits light by applying a negative electrode type voltage are also provided, and these four fields are repeated. And since the switching circuits TH1 to TH6 are composed of the thyrister, the starting of the applying voltage can be made sufficiently steep. As a result, a steep pulse can be applied to the whole surface of a membranous EL panel, and thereby the pulse width of the ageing can be made sufficiently narrow. Consequently, a defect owing to a dielectric breakdown can be reduced.
