Title: Production of pore sealed thermally sprayed layer
Inventor: KITAMURA YASUSHI
IPC: C23C4/18
Filed: 1987-11-30
Abstract: PURPOSE:To surely fill a liq. resin for pore sealing into the pores in a thermally sprayed layer and to set to resin in the filled state by using a photosetting liq. resin as a pore sealing agent and applying the resin at a high temp. CONSTITUTION:A photosetting liq. resin 3 is used as a pore sealing agent. When the resin 3 is applied at a high temp., it does not set during application and uneven application is not caused. Since the viscosity of the resin 3 is low at the high temp., the resin 3 penetrates easily into the pores in a thermally sprayed layer 2. The applied resin 3 is cooled to a temp. below the application temp. and set by irradiation with light. By the cooling, the air in the pores in the layer 2 is constricted and the resin 3 on the surface of the layer 2 is sucked into the pores to ensure filling.

Abstract: PROBLEM TO BE SOLVED: To easily adapt a second disk cartridge to a floppy disk apparatus comformed to a first disk cartridge, by providing an adapter having a lateral width in conformity with a standard of the first disk cartridge and comprising a holding means of the inserted second disk cartridge. SOLUTION: An adapter 20 is formed of plastic in a schematically U shape with holding parts 20a, 20b directed slightly inward so as to hold corresponding end parts of side faces 21a, 21b of a 3.5-inch floppy disk cartridge 21. A groove 20c corresponding to a lower end 21c of the cartridge 21 is formed at the inside of the adapter 20. A lateral width of the adapter 20 is made equal to a lateral width of a large capacity floppy disk cartridge. Accordingly, after the cartridge 21 is inserted in the adapter 20, the cartridge 21 is held by the groove 20c and holding parts 20a, 20b. Since the lateral width of the large capacity floppy disk cartridge is the same as a longitudinal width thereof, the adapter can cope with floppy disks conforming to the large capacity floppy disk cartridge.  Floppy disks conforming to the large capacity floppy disk cartridge can be handled in the 3.5-inch floppy disk cartridge 21.

Title: Manufacture of semiconductor film
Inventor: NAKAJIMA YUKIO
IPC: C23C16/24
Filed: 1986-12-18
Abstract: PURPOSE:To improve the absorption coefficient in optical characteristics by reducing the quantity of an SiH2 coupling with respect to the SiH coupling in a film by adding an SiH4 gas as a reactive gas to an Si2H6 gas. CONSTITUTION:A reactive gas is introduced in a reaction chamber 1 and a semiconductor film is obtained by using optical CVD which directly decomposes the reactive gas by the light energy from a light source which radiates the wavelength in an ultraviolet region. In this case, the reactive gas contains at least a monosilane SiH4 gas 8a and a disilane Si2H6 gas 8b. Then, the SiH4 gas reacts with the radical formed by decomposing the Si2H6 gas, a new radical is formed and the radical reduces the quantity of an SiH2 coupling against the SiH coupling in a film. This improves the absorption coefficient in optical characteristics.

Title: Image reading device
Inventor: INAGE OSAMU
IPC: H04N1/19
Filed: 1993-12-02
Abstract: PURPOSE:To eliminate the after images and to suppress the rise of cost of an image reading device by performing the original reading operations every second line between the lighting and non-lighting states of a light source. CONSTITUTION:A light source 13 is turned on and off every second line of an original by a light source driving part 57 according to the instructions of a sequence control part 58. A CCD 17 operates by the clocks phiTG, phi1, phi2, phiR1, phiR2, etc., generated by a driving timing generating circuit 56 and based on the signal received from the part 58. Then the image signals accumulated in the photoelements of the CCD 17 are sent to a shift register by the clock phiTG in an OFF period of the light source 13. The image signals are outputted from the shift register for each pixel by the shift gate clock received from the circuit 56. Meanwhile the image signals supplied from the CCD 17 form an after image that is not outputted when the precedent reading line of the original is read. Thus the CCD 17 turns off the light source 13 and then reads idle the original in order to acquire the image signals free from any residual image when the next reading line is read.

Abstract: PROBLEM TO BE SOLVED: To obtain data for measuring a sectional shape of a rail while running at a high speed, and measure the sectional shape with high precision, by obtaining the imaging information of a measured part of the rail from an imaging means, and obtaining a directional vector of the rail from a directional vector measuring means. SOLUTION: On an imaging screen of a camera 15, an image of an outer shape of a measured part of a rail which is seen as a band of a light by irradiation of a plane light is imaged, and the band of the light has a width. When the measured part on the imaging screen of the camera 15 is recognized in the state that the light band has the width, measuring precision of coodinates, on a camera coodinate system, of the measured part of the rail is deteriorated. Luminance values of the respective pixels on the imaging screen of the camera 15 are detected, and a pixel having a peak value is extracted. By substituting coodinates, on the camera coodinate system, of the respective points on a rail section 14 into a specified formula, the coodinates on a space coodinate system, of the respective points of the measuring positions of the rail can be obtained.  By projection on a plane rectagular to the direction vector of the rail, a sectional shape perpendicular to the longitudinal direction of the rail can be measured.

Abstract: PROBLEM TO BE SOLVED: To observe sufficiently clear projected picture even under a bright and wide condition without reducing the service life of a lamp while reducing the power consumption by increasing the driving voltage of the lamp at the point of time when the emitted light quantity of the lamp becomes a prescribed value. SOLUTION: A control section 50 obtains the data of an illuminating section from an emitted light quantity data holding section 51 which holds the data of emitted light quanties at the beginning and the end of a service life as the data of the illuminating section. The section 50 control a first power supply 53 so that the power supply 53 applies a normal voltage to a lamp 1.
