Title: Manufacture for ultrasonic wave delay line
Inventor: IINO TAKESHI
IPC: H03H3/007
Filed: 1981-02-23
Abstract: PURPOSE:To reduce secular change in a delay time for an ultrasonic wave delay line, by eliminating the distortion of surface of glass through etching processing, after cutting the glass block of a delay medium in the shape of a delay line. CONSTITUTION:An ultrasonic wave delay line element is formed, by cutting a glass block 1 of a delay medium consisting essentially of SiO2, Pb3O4 as shown in two lines A. Only the glass part of the delay line element is immersed in an etching liquid for etching processing and after the etching processing is finished, the etching liquid is neutralized and further, water rinsing is made by pure water. Then, the distortion on the surface of glass can be eliminated. Thus, the secular change in the delay time can be reduced.

Title: Bearing device for rotating shaft
Inventor: OTSU SHINKI
IPC: F16F15/30
Filed: 1989-02-03
Abstract: PURPOSE:To operate a rotating shaft at an optimum oscillating condition, and thereby contrive to increase the number of revolutions and to lengthen the life of it by letting a part of piezo-electric elements arranged between a bearing hold section and a support frame act as a detector, and letting the other ones of them act as a driver, and thereby applying voltage determined by the magnitude of oscillation to said driving elements. CONSTITUTION:Detecting piezo-electric elements 6a and 6b and driving piezo-electric elements 7a and 7b are provided between a bearing hold section 4 holding a bearing 4 and a support frame 3. The direction of rotating oscillation is judged by a judging section 10 based on signals from the detecting piezo-electric elements 6a and 6b, and operation is processed by a control section 11 together with a revolution detector 8 so as to be inputted into a voltage generating sections 12a and 12b together with signals from the detecting piezo-electric elements 6a and 6b while the out put is being inputted into the driving piezo-electric elements 7a and 7b so that the bearing hold section 4 is thereby driven. This permits, the damping force of the bearing to be changed in response to the number of revolutions to operate a rotating shaft at an optimum oscillating condition, thereby making it possible to increase the number of revolutions and also to lengthen the life of it.

Title: Electrostatic charge image developing full-color toner
Inventor: KIDO KENICHI
IPC: G03G9/08
Filed: 1995-02-14
Abstract: PURPOSE: To obtain a toner having stable electrification property which is hardly influenced by the change of temp. and environment and to obtain a sharp image without fog by externally adding flaked fine particles of titanium oxide to a full-color toner comprised of a coloring agent and a binder resin. CONSTITUTION: Flaked fine particles of titanium oxide are externally added to a full-color toner comprised of a coloring agent and a binder resin. The flaked titanium oxide particles to be externally added have 5-40nm average particle diameter, preferably 5-30nm. It is preferable to use such titanium oxide particles that the surface of particles is treated to be made hydrophobic in a water-base material, or further treated to be made hydrophobic in a gas phase. The flaked titania is usually mixed by 0.5-2.0wt.% to the toner, preferably 0.5-1.5wt.%. Thereby, good deposition and dispersion property of the titanium oxide fine particles to the toner is obtd. Thus, spent of the carrier is prevented, stable electrification is obtd. and durability is improved.  Since the additive had good dispersibility, the effect to modify the toner surface is increased and fluidity or the like can be improved.

Title: Production of low-molecular weight water-soluble chitosan
Inventor: TANZAWA TOMOYA
IPC: A61K8/73
Filed: 1986-02-07
Abstract: PURPOSE:To obtain low-MW water-soluble chitosan useful for, e.g., drugs easily in good yields, by soaking chitosan in an aqueous solution of a nitrite, acidifying the reaction system by the addition of an acidic substance and effecting a MW reduction of the chitosan. CONSTITUTION:Chitosan is produced by, for example, a method comprising deacetylating chitin obtained by deashing and deproteinizing the shells of crabs. The obtained chitosan is soaked in an aqueous solution of a nitrile (e.g., sodium nitrite) to impregnate the porous chitosan uniformly with the nitrite. The pH of the reaction system is adjusted to 5 or below by the addition of an acidic substance (e.g., acetic acid or hydrochloric acid), and the whole system is agitated to effect a MW reduction of the chitosan. It is desirable that a nitrite is further added to the reaction system after the acidic substance has been added to it. After the reaction, the reaction mixture solution is neutralized to obtain the purpose water-soluble chitosan of a decreased MW.
