Title: Filter having excellent compaction resistance
Inventor: KONDO YOSHIKAZU
IPC: C08G77/06
Filed: 1985-03-06
Abstract: PURPOSE:To obtain the title filter having excellent compaction resistance and capable of being used under high pressure by forming the plasma-polymerized film of an organosiloxane compd. shown by the specified formula in a hydrophilic porous membrane. CONSTITUTION:A hydrophilic porous membrane of cellulose acetate, etc., is used as a substrate, which is placed on the lower electrode cooled by a refriger ant in a reactor. A gaseous organosiloxane monomer such as hexa methylcyclotrisiloxane shown by the formula is introduced between electrodes in a reactor which is kept at reduced pressure. A high-frequency wave is im pressed between the electrodes to generate low-temp. plasma and a plasma- polymerized film is formed on the porous membrane. In this case, the pore diameter of the porous membrane, the polymerization rate and the flow condi tion of the plasma are appropriately combined to form the plasma-polymerized film on the surface and at the inside of the porous membrane. Consequently, the creep property and hydrophilicity of the filter material are eliminated and a filter having excellent resistance can be obtained.

Title: Diaphragm for speaker
Inventor: NAKAO KANJI
IPC: H04R7/10
Filed: 1983-03-17
Abstract: PURPOSE:To improve the efficiency of a speaker unit and to expand a flat region in a sound pressure versus frequency characteristic by adhering a thin film layer made of B or Be on both faces of a honey-comb core formed by a resin-formed thin film. CONSTITUTION:A diaphragm for speaker 3 is of sandwich construction where a honey-comb core 1 made of a resin-formed thin film is used as a core member and a skin member 2 made of a boron thin film is fixed to both faces. Since this diaphragm 3 uses the core 1 formed by a resin with light specific gravity, the efficiency of the speaker unit is more excellent than a diaphragm with a core 1 formed by an Al alloy. Since boron is used as the skin member 2, the specific elastic modulus is increased and the flat region in the sound pressure versus frequency characteristic is expnaded. Furthermore, the similar effect is attained in using Be in place of B for the thin film layer of the skin member 2.

Title: Steering structure for two wheeler
Inventor: HANAWA NOBUMICHI
IPC: F16F9/44
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To make rust hard to be caused in an operation part, and to permanently ensure operability by arranging a rotary damper on a bracket, and positioning the operation part capable of adjusting a degree of damping force generated by the rotary damper on an outside surface being an almost vertical surface of the rotary damper. SOLUTION: In a rotary damper, a vane 22 has a fixed orifice for allowing communication of both oil chambers R1, R2, and while prescribed damping force is generated by this fixed orifice, the damping force generated by this fixed orifice is adjusted in a degree by a needle 30. An upper bracket 2 has a mount part formed in a lateral directional bar shape on an upper end surface for forming a horizontal hole 2f, and thus, an operation part 30b is positioned on a right side surface being an almost vertical surface of this mount part, so that since a chance of being exposed to rainwater is reduced more than when the operation part is arranged on an upper end surface of the upper bracket 2, rust is hardly caused in an operation part 30b part.

Title: Electron gun
Inventor: HOTSUTA SADAKICHI
IPC: H01J29/04
Filed: 1978-04-18
Abstract: PURPOSE:To obtain a quick-operating type miniature high-precision electron gun of low power consumption by eliminating the need of a heating part by composing the electron gun of an anode emitting an electromagnetic wave by electron impulse and a cathode emitting electrons when the electromagnetic wave strikes. CONSTITUTION:After being accelerated by an electric field applied between cathode 2 and anode 1, an electron emitted in a certain method is caused to strike anode 1, from which an electromagnetic wave is obtained through electric-electromagnetic wave conversion. When the radiation from anode 1 is isotropic, 50% of the radiated electromagnetic wave reaches cathode 2. The electromagnetic wave reaching cathode 2 causes cathode 2 to emit electrons. Then, the electrons are caused to strike anode 1. The above process is repeated to multiply the electrons and some of them pass through aperture 5 of anode 1 to form an electron beam. The seed of electrons requires only a few electrons existing naturally.

Abstract: PURPOSE: To ensure the exhibition of the maximum and minimum performance for the electronic computer by securing the optimum program size and the execution time by means of the value of the program counter, the basic clock and the interruption flag.  
     CONSTITUTION: Computer clock 1, program counter value 2 and interruption signal 3 are used as input given from the computer in order to obtain measuring output 17. FF13 is reset when signal 3 is produced under measurement or when a coincidence is obtained between counter value 2 and end address register 9. And count register 16 takes in the contents of counter 15 when value 2 reaches the measuring end address to secure output 17. Output 17 shows the value which is proportional to the execution time of the measured program which is renewed every time when the counter value passes through the measuring end address. Thus, the value is displayed and recorded through the meter, printer, display and others. Thus, the dynamic measurement is possible for the running time at an optional area of the program to ne measured.

Title: Wipable ink composition for writing utensil
Inventor: HOSODA TORU
IPC: G09B29/00
Filed: 1987-03-03
Abstract: PURPOSE:To obtain the title ink composition which gives a written image with good wipability, by mixing a coloring agent comprising colored spherical resin particles, a binder, and a liquid medium. CONSTITUTION:The title ink composition is prepared by mixing a coloring agent comprising colored spherical resin particles suitably having a particle diameter of 0.1-1.0mum, obtained by coloring PS, PVC, etc., with a suitable dye or pigment; a binder obtainable by a known method of mixing and polymeri zation from a hydrophilic monomer and a lipophilic monomer; and a liquid medium preferably comprising a volatile organic solvent or a mixture of a volatile organic solvent with a hardly volatile organic solvent. This ink composi tion can be easily wiped off since the area of the colored resin particles in contact with a writing surface is small when the organic solvent dries by evapo ration after writing so that these particles weakly adheres to the writing surface. It can also be completely wiped off since the particles of the coloring agent do not penetrate into pinholes, etc. even if minute surface ruggednesses and pinholes exist on the writing surface.
