Title: Picture information reader
Inventor: OISHI NOZOMI
IPC: H04N1/19
Filed: 1987-10-21
Abstract: PURPOSE:To attain original reading with high accuracy by providing a reflecting light regulation member between an original and a light source for lighting original of a picture reader so as to reduce the uneven luminous quantity in the original read section. CONSTITUTION:When a fluorescent lamp 17 is lighted, the light L1 radiated from the lamp 17 transmits through the beam splitter 16 as the reflecting light regulation member arranged between the light source 12 and the original 11 from non-coating face 16b to the coating face 16a side by nearly full quantity and reaches the face of the original 11. The light L1 radiated on the original 11 is reflected irregularly and the part becomes a reflected light L2 and goes to the light source 12 and reflects on the coating face 16 of the beam splitter 16 and most of the light is reflected in the direction A. Thus, the re-lighting of the original 11 by the irregularly reflected light is not caused and the irregularly reflected light L3 having uniform lightness is always obtained from the original 11. Then the light L3 is reflected in the mirror 13 and made incident in the lens 14 and the image is formed on a linear image sensor 15. Thus, the original reading with high accuracy is attained.

Title: Plastic magnet and magnet roller
Inventor: ISHIGURO KENICHI
IPC: H01F7/02
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To obtain a plastic magnet having a large magnetic force with less deformation by extrusion molding. SOLUTION: A mixed material or a kneaded material of the binder comprising resin or rubber, magnetic power and the resin-based lubricant comprising a monomer unit different from the monomer unit of the above described binder is molded. Since the monomer units of the resin or the rubber and the resin- based lubricant are different, the compatibility of the resin or the rubber and the lubricant does not become high even if the material is heated in a molding machine. Therefore, the most of lubricant does not enter between the molecules of the resin or the rubber. Therefore, the large amount of the resin-based lubricant is presence between the material and the inner surface of the oriented die. The fluidity of the material itself can reduce the contact resistance between the material and the oriented die without improving the fluidity as in metallic salt and fatty acid amide.  Therefore, the magnet having the large magnetic force can be obtained.

Inventor: MASUKO AKINOBU
IPC: H04N7/173
Filed: 1984-12-20
Abstract: PURPOSE:To make it possible easily to confirm a carrier wave outgo at an adjustment time by displaying for a designated carrier frequency that a carrier wave is outgone from a subscriber side to a feeder cable. CONSTITUTION:A CPU15 produces a pseudolike transmission request signal (RST signal) according as a command which was sent by utilizing an idle command of a remote controlled sender 20 and consequently produces a transmission frequency selective (SEL). These two signals; those of RST and SEL are supplied to a carrier wave frequency setting circuit 40 and then produce a signal which changes an oscillation frequency of an oscillator 50; for instance, its frequency to f1 or f2. The oscillation frequency of oscillator 50 which was designated by a control signal produced at this carrier wave setting circuit 40 performs a phase modulation of a pseudodata which was set, for example, to the CPU15 by means of a multiplier 70 and then sends out a carrier wave frequency signal to be adjusted through an amplifier 80 to the feeder cable side. A carrier wave which is outgone in that case is detected by a carrier wave outgoing display mode 110 and it is displayed accordingly.

Abstract: PURPOSE:To reduce the size of a gap between a rotating drum and an opposed part, to prevent a magnetic tape from being wound into the rotating drum, to make heat transfer to the drum excellent and to eliminate dew condensation by directly fitting a holder in a fixed drum with the aid of a fitting part. CONSTITUTION:The size of the gap between the rotating drum 4 and the opposed part 22 is reduced by directly fitting the holder 20 in the fixed drum 2 with the aid of the fitting part 21. Therefore, the surface of the magnetic tape where the dew condensation occurs is prevented from being stuck and wound into the drum 4 with the aid of the opposed part 22. Since the gap between the upper surface of the drum 4 and a bridge part 23 is small, the tape is prevented from running on the upper surface of the drum 4. Furthermore, by burying an organic positive characteristic thermistor 24 in the fitting part 21, heat generated in the thermistor 24 is efficiently transferred to the drums 2 and 4 and the dew condensation occurring on the drum is eliminated in a short time.

Filed: 1986-11-11
Abstract: PURPOSE:To reduce the maximum sintering temperature and to reduce sintering cost in producing glass by sol-gel method, by immersing gel in a solution obtained by hydrolyzing an alkyl silicate with an acid and aging in aging process of gel. CONSTITUTION:A sol solution is prepared by a method wherein ultrafine silica is dispersed into a solution obtained by hydrolyzing an alkyl silicate with an acid. Then the sol solution is adjusted to proper pH, gelatinized and the gelatinized material is aged in a state wherein the gelatinized material is immersed in the acidic hydrolyzed solution of the alkyl silicate. Then the aged gel is taken out from the solution, dried and sintered to produce glass. Consequently, a hydrolysis intermediate component (e.g. component shown by the formula) of the alkyl silicate can be impregnated into the gel while the gel is being aged. Consequently, the gel can be densified at a lower temperature by sintering and the maximum sintering temperature can be lowered.

A graph registration 4 registers the content of a picture processing function selected in the area setting mode, that is, an area, a line segment, a position or the like subjected to picture processing. When a coordinate input section 2 is pressed to enter one coordinate or over and to set an area or the like subjected to picture processing and an optional coordinate is pressed twice, the set area or the like is registered in the graph registration section 4. When the graph registration section 4 is desired to be cleared due to wrong setting or the like, the above described optional coordinate is pressed once more, then the content of the graph registration 4 is cleared and re-registration is attained.

Abstract: PURPOSE:To shorten the construction them and save civil engineering costs by forming cavities around a buried pipe using a discharged liquid from a fluid type excavating tool, and grinding the outer surface of the buried pipe with reciprocative motion of a grinding tool placed in the cavity. CONSTITUTION:Existing invention applies to a grinding method for an underground buried pipe P, whereby fluid is discharged into soil from the discharge hole at the tip of a fluid type excavating tool 6 inserted into the ground so as to soften the soil around the buried pipe P. Then the soil is exhausted by a suction removing tool 7, and a large dia. cavity 8 is formed around the buried pipe P. A grinding tool 18 coupled with a spherical file is inserted into this cavity 8 from an underground hole 2 and wound fast on the buried pipe P. Then operational members 19a, 19b of the grinding tool 18 led onto the ground are operated to reciprocate the grinding tool 18 in the circumferential direction of buried pipe P, and thus the outside surface of the buried pipe P is ground. This shortens the construction term greatly and suppresses the civil engineering costs to a great extent.
