Title: Toner for pressure fixing
Inventor: AMAKAI YOSHIMI
IPC: G03G9/087
Filed: 1980-05-01
Abstract: PURPOSE:To obtain a superior toner causing little fluidity to a toner image after pressure fixing, having especially stable triboelectric charging properties and not polluting a carrier, etc. by adding a graft copolymer of a specified crystalline polymer and a specified amorphous polymer to a toner. CONSTITUTION:A 85-30wt% amorphous polymer having >=45 deg.C glass transition point and obtd. by using >=1 kinds of vinyl monomers such as styrene and n-butyl methacrylate is grafted on a 15-70wt% crystalline polymer having 45-200 deg.C m.p. and obtd. by using >=1 kinds of monomers selected from ethylene, propylene and vinyl acetate. The resulting graft copolymer is used as a binder for a pressure fixing toner. The copolymer is melted, kneaded with a colorant such as carbon black or magnetic powder, pulverized, and sieved to obtain the toner. Thus, the blocking of toner particles is prevented, and no toner is stuck to a rotor, etc. in the manufacturing process.

Title: Electrification preventing shoe
Inventor: MIYATA HIROSHI
IPC: A43B21/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To naturally discharge the static electricity charged on a human body during a walk by providing a conductive part on the surface of the inner sole or insole of a shoe, and connecting the conductive part to the ground section of a sole for an electric discharge. SOLUTION: A conductive part 1 is stuck to the surface of an inner sole 6, and a ground section 2 made of a metal wire is inserted into a sole 5 to be connected to the ground. When hands and feet are moved during a walk, clothes are brought into contact with each other, and high-voltage static electricity is accumulated on a human body. This static electricity passes through a junction 3 from the conductive part 1 kept in contact with the sock, it flows to the ground kept in contact with the lower face of the sole 5 from the ground section 2, and the high voltage is reduced. Since the static electricity is reduced, the entangling of a skirt and the shock of an electric discharge when a person touches a metal such as a door knob or gets in or out of a vehicle can be prevented.  If the conductive part 1 is kept in contact with a foot to cause uncomfortableness, the insole 7 woven with a copper wire is used, the continuity to the conductive part 1 is secured, and the odor of the foot can be prevented by the antibacterial action of the copper wire.

Title: Spectrum display method and spectrum analyzer
Inventor: SAITO DAISUKE
IPC: G01R23/173
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To enable expansive and contractive displays in an immovable set position by obtaining an offset amount from the set information of a specified level position, multiplying a difference signal between a DC signal from a frequency converter part and the offset amount by an amplification set value and adding the offset amount to tha product. SOLUTION: A position level is figured out as a predetermined offset amount 11of by receiving the set information of a specified level position on the display pipe surface. An offset subtraction part subtracts the predetermined offset amount 11of from an analog DC signal. A multiplication part multiplies the subtracted difference signal 10b by an amplification set value corresponding to the predetermined resolution setting of a display on the pipe surface. An offset addision part adds the predetermined amount 11of to the product to send the sum to an A/D converter. Thus, the set position is kept immovable so that a display spectrum can be expanded or contracted. Hence, the expansion and contraction in the specified level position on the pipr surface are facilitated extremely.
