Title: Electronicphotographic device
Inventor: TACHIKAWA MASAICHIRO
IPC: G03G15/00
Filed: 1986-09-29
Abstract: PURPOSE:To obtain a satisfactory toner image transfer by providing a first layer composed of a semiconductor in which an electric resistance is special and a second layer composed of the material in which the electric resistance is a specified value or above, and transferring electrostatically a toner particle onto a copying paper inserted between a conveying means and a belt means. CONSTITUTION:A conveying belt 26 is composed of a substrate layer 42 as the first layer composed of a semiconductor material in which an electric resistance is 10<10>-10<13>OMEGA.cm and a front surface layer 44 as the second layer composed of the material in which the electric resistance is >=10<10>OMEGA.cm. A + charge is supplied by a transferring charger 34, a copying paper 17 is polarized by the + charge, the electrostatic attracting force of a true charge on the conveying belt 26 and the polarizing charge of the copying paper 17 is generated and the copying paper 17 is adsorbed onto the conveying belt 26. The force to transfer a toner particle on the photosensitive body 10 is generated by the charge supplied to the conveying belt 26. Thus, when the electric resistance value of the conveying belt 26 is specified, the transfer of the stable toner particle can be maintained regardless of the type of the copying paper 17 used and the environment, in which the copying paper 17 is placed.

IPC: C04B35/64
Filed: 1998-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain a hexagonal boron nitride sintered product having excellent deformation resistance during employment under a high strength and a high temperature by an atmospheric pressure sintering method. SOLUTION: This hexagonal boron nitride sintered product has a three point bending strength of >=20 Mpa at ordinary temperature and a deformation resistance index of <0.75. This method for producing the hexagonal boron nitride sintered product comprises sintering a molded raw material containing boron nitride powder in an inert gas atmosphere having a nitrogen component content of <=10 vol.% (including zero). Therein, the boron nitride powder contains oxygen incapable of being removed with methanol in an amount of 0.4-1.7 wt.%, and 30-60 wt.% of the oxygen is released, when the boron nitride powder is held in a helium gas atmosphere at a temperature of 1,800 deg.C for 180 min.

Abstract: PROBLEM TO BE SOLVED: To prevent a thread from running from the sewing end of a sea and cut the thread end of a looper thread short by providing a step etc., for cutting the looper thread hooked on an engagement means at the engagement part in forming a seam on a fabric by a double chain stitch sewing machine. SOLUTION: While a fabric W is sent in the F direction by a feed dog 2, a seam S of a stitch form 406 is formed by needle threads 8, 9 and a looper thread 10 which are threaded through left/right needles 5, 6 and a looper 3 respectively. Then, the operation of an air cylinder rotates a hook knife 16 so that a hook 15 is moved from the back of the looper 3 across the front and catches the looper thread 10 which continues to an eyelet 3e of the looper 3 from the fabric W. After the left/right needles 5, 6 are lowered, the looper thread 10 is engaged with the hook in a position a little before the needle so as to form a rather long loop and the engagement part of the looper thread which is engaged with the hook 15 is cut by the inverse rotational movement of the hook knife 16.

Title: Package for recording and reproducing medium
Inventor: NAKAMATSU YOSHIROU
IPC: G11B23/033
Filed: 1983-12-08
Abstract: PURPOSE:To reduce the generation of errors and drop-outs and to prevent the thermal expansion of a disk, the bending of a jacket, etc., by mixing a conductor such as the metallic powder into a sheet or a molded matter. CONSTITUTION:The metallic powder such as aluminum powder or brass powder 7 is mixed with polyvinyl chloride acetate to obtain a sheet. This sheet is formed into a square jacket 2, and a magnetic disk 1 for record/reproduction is enclosed into the jacket 2. The disk 1 is produced by coating a magnetic layer onto the surface of a disk made of a flexlble sheet of polyethylene terephthalate, for example, and has a rotary shaft hole 3. The jacket 2 has small electric resistance since it contains the metallic powder 7, and the static electricity generated from the jacket 2 can be removed satisfactorily. This eliminates attachment of foreign matters on the jacket 2 and decreases greatly the drop-outs produced by the record and reproduction. Furthermore the heat is reflected by the powder 7 to avoid the expansion of the disk 1 due to heat or the deformation of the jacket 2 due to bending.

Filed: 1992-08-31
Abstract: PURPOSE:To reduce the power consumption of an integrated circuit and also to eliminate the malfunctions of other circuits by using an NPN transistor TR to perform a switching operation in order to decide whether the power should be supplied to a load circuit or not. CONSTITUTION:A TR Q12 is turned on a soon as the positive voltage impressed to an input terminal 3 is inputted to a load circuit 12. Then, all TRs of a switch circuit 7 are turned on. A point (a) is connected to an earth line 10 when a TR Q9 is turned on, and a TR Q3 of a power supply start circuit 4 is turned on. Then, all TRs of a power circuit 5 are turned on and the circuit 5 starts its operation to supply a constant current to the circuit 12. When the positive voltage is not impressed to the terminal 3, all TRs of the circuit 7 are turned off and at the same time all TRs of both circuits 4 and 5 are also turned off. Thus, a constant current is not supplied to the circuit 12 and the circuit 12 is not actuated. In such as way, the circuit 7 performs a switching operation to decide whether the power should be supplied to the circuit 12 or not by the Tr of switch circuit. Therefore, the malfunctions of other circuits can be eliminated and the power consumption of an integrated circuit can be reduced.

Title: Method for demagnetizing hull
Inventor: TAKAHATA MITSUHIRO
IPC: H01F13/00
Filed: 1990-08-31
Abstract: PURPOSE:To mathematically efficiently demagnetize a hull and, at the same time, to minimize the magnetic field in a specific direction by finding the magnetic moment of the hull by calculating dipole moments from the three component data of magnetic fields. CONSTITUTION:A plurality of magnetic sensors D1-DN are arranged below a hull 1. The magnetic field and coil effect of the hull in an un-demagnetized state are calculated as a plurality of dipole moments from the three components Hx, Hy, and Hz of the magnetic fields detected by the magnetic sensors. The magnetic moments are reduced by calculating the dipole moments as a magnetic source. In this demagnetizing method, the magnitude of the magnetic source becomes clear, since the plurality of dipole moments at a specific position in the hull are specified from the magnetism detected data on three axes of Hx, Hy, and Hz. The coil effect can also be specified from the moment of the specified position.

IPC: G03G15/22
Filed: 1988-09-17
Abstract: PURPOSE:To protect an image from an effect that character, etc., is written in the image by inhibiting the write of the character when an original image is read and the write position of the character with the aid of a write means is overlapped on a developed image. CONSTITUTION:The original image formed by exposing and scanning an original is read and stored in a memory 83. Then, an area where desired information is written by the write means (write unit 71) is collated with the area of the original image stored in the memory 83. When the area where the desired information is written by the write means 71 is overlapped on the original image, by judging based on the collated result, the write with the aid of a write control means 84 is inhibited to the area of the original image. Thus, the formed image can be prevented from being erased and the image can be protected from the effect that the character, etc., is written in the image.
