IPC: G03G15/20
Filed: 1988-02-08
Abstract: PURPOSE:To obtain an image of a high quality whose light transmissivity is uniform extending from the tip of the image to the rear end by making a rotating speed of a heat fixing roller lower than a steady speed when an OHP sheet passes through and also, decelerating its speed in accordance with passing of the OHP sheet. CONSTITUTION:When it is detected by a recording material detecting means 70 that a recording materials is an OHP (overprojector) sheet and also, it is detected by a tip detecting means 58 that the tip of the OHP sheet has reached a contact position between a pair of heat fixing rollers 42, 44 made of rubber, a rotating speed of the heat fixing rollers 42, 44 is decelerated in accordance with passing of the OHP sheet, and when it is detected by a rear end detecting means 58 that the rear end of the OHP sheet has reached the contact position between the rollers, the rotating speed of the heat fixing rollers 42, 44 is returned to a steady speed.

Title: Long heat pipe for heat transfer
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/04
Filed: 1982-02-22
Abstract: PURPOSE:To enable the long distance heat transfer by a structure wherein a large number of thread of ultrafine yarns are densely attached onto the inner peripheral surface of a flexible tubular body and are pressed by a corrugated tube perforated with a large number of small holes in the heat pipe for power cable use or the like. CONSTITUTION:In the heat pipe, the loop flow passage of liquid phase working fluid is formed by the fine gaps between the ultrafine yarns 3, which are made of glass fibers or the like and out of which a large number of threads densely attached along the direction of axis line of the pipe onto the inner peripheral surface of the flexible metallic tubular body 2 are made. Furthermore, the corrugated tube 4 perforated with a large number of small holes 5 is inserted in the inner peripheral side of said ultrafine yarn layer so as to urge the ultrafine yarns 3 against the inner peripheral surface of the tubular body 2 in order to partition the passage of gaseous phase working fluid and of the liquid phase working fluid with the corrugated tube 4. Accordingly, effective capillary tube radii become small and, as a result, high capillarity pressure can be obtained and, furthermore, the pressure losses in the respective passages are small and consequently long distance heat transfer can be made possible.

Title: Inspection medium for magnetic memory device
Inventor: OOYA TAKEO
IPC: G11B5/455
Filed: 1985-02-14
Abstract: PURPOSE:To measure accurately the azimuth error of a magnetic head without a specific skilled operator by providing a noise block at both sides of a data block. CONSTITUTION:The noise blocks 31-37 and 41-47 are installed at both sides of the data blocks 21-27, and their inclinations of the noise blocks with respect to the data blocks are opposite each other. The readout output of data information from the noise block at one side with respect to the readout output of data information from the blocks 21-27 is large, while the readout output from the other side is small. In terms of the total of the readout outputs from the blocks 21-27, 31-37 and 41-47, a change in the output value with respect to the inclination becomes large. Thus the azimuth error of the magnetic head can be accurately measured without specific testing equipment and the specific skilled operator.

Filed: 1986-02-10
Abstract: PURPOSE:To have polishing power and wear resistance and to improve durability by using alumina particles as a polishing material and incorporating TiO2 therein at 2-30wt% by the weight of the alumina particles.

Title: Hot rolling method for one-directional silicon steel plate
Inventor: HARATAN TSUTOMU
IPC: C21D8/12
Filed: 1979-03-09
Abstract: PURPOSE:To prevent the generation of linear granules of moldings by a method wherein the recrystallizing rolling of 30% or more is performed within a specified temperature range when passing through an arbitary pass during finishing rolling when slab, whose grains are grown by heating at a high temperature, is worked in fixed thickness by means of hot rolling when manufacturing a silicon steel plate. CONSTITUTION:Slab for a silicon steel plate containing 2-4% Si, and 0.025- 0.085% C and one kind or more of Al, N, Mn, S, Se, Te, Sb, etc. as inhibitor elements is heated at a high temperature, subject to recrystallizing rolling by means of hot rolling, and formed in a hot rolled plate. in this case, the plate is controlled so that a gamma phase be precipitated in 3% or more into a alpha phase matrix in structures just before recrystallizing rolling. The plate is subject to recrystallizing high rolling reduction rolling which the rate of rolling reduction is 30% or more per one pass within a temperature range of 1230-960 deg.C. The plate is rolled to the final thickness by carrying out the rolling at a time or more, decarbonizing-annealed, and finally annealed, thus obtaining the one-directional silicon steel plate, which has no linear granule and is easy to be magnetized in the rolling direction.

Title: Image reader
Inventor: KUSUMOTO KEIJI
IPC: H04N1/401
Filed: 1993-02-17
Abstract: PURPOSE:To read highly accurate image data for shading correction by setting the scanning speed of a scanning means at a value lower than the one in the case of reading normal image data at the time of reading the image data for the shading correction by a scanning control means. CONSTITUTION:At the time of reading the data for the shading correction, the moving speed of a scanner slows down when the first driving clock signal of a low frequency is used. Thus, the received light quantity of a CCD (color image sensor) 201 per unit time increases and there is the possibility of exceeding the allowable received light quantity of the CCD 201. Thus, a voltage V2 lower than the voltage V1 at the time of reading real image data is set for the voltage applied to an exposing lamp 250. Thus, a voltage controllable lamp power source 240 and a CPU 230 are connected and the power source 240 switches an output voltage to V1 and V2 corresponding to the output of selecting signals. Thus, the data for the shading correction with less noise can be read.

Title: Address allocating method in inter-plural point communication, communicating method among plural points and its connecting device
Inventor: OKADA KOICHI
IPC: H04L45/741
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To reduce the setting burden of 2nd point sides by allocating an address which is different from that of a destination terminal connected to a terminal in the 2nd points but common among all of the 2nd points. SOLUTION: 2nd points 200 respectively have an address converting part such as PROXY server and fire wall for converting the private address of a client machine 201 into a global address. In a network connecting plural points, connection destinations of communication data having the same connection destination address are divided by converting the connection destination address into the address of a connection destination terminal for the communication data on a communication path between one point to which the terminal to be a connection destination candidate belongs and a connection source. Thus, it is possible for the 2nd points 200 to easily and directly communicate with a network 1 and to construct a virtual private network(VPN).
