Title: Preparation of co-enzyme q
Inventor: IMAMURA SHIROU
IPC: C12P7/66
Filed: 1977-09-21
Abstract: PURPOSE:To prepare co-enzyme Q in high degree of extraction using small amount of solvent, by extracting co-enzyme Q from animal or plant tissue or from microbial cells using a mixture of a hydrophilic solvent and a hydrophobic solvent as extractant, separating the extract into two phases, and separating the co-enzyme Q from the phase of the hydrophobic solvent. CONSTITUTION:Microbial cells such as Phodotorula mucilaginosa (AHu-39, 46) containing co-enzyme Q10 , baker's yeast containing coenzyme Q6 etc., or tissue of animals or plants, are extracted with a mixture of a hydrophilic solvent and a hydrophobic solvent at an azeotropic point of the mixture for 0.5-4hr. After removing the microbial cells, the extract is added with water and allowed to cool thereby separating the mixture into two phases. The hydrophobic solvent phase, which contains the co-enzyme Q, is evaporated to dryness, dissolved in methanol, and saponified with alkali, pyrogallol, etc. to obtain crude crystals containing co-enzyme Q.

Title: Device of confirming dump angle of dump car
Inventor: NANUN DAISUKE
IPC: B60P1/28
Filed: 1984-06-04
Abstract: PURPOSE:To facilitate confirmation of a dump angle, by a method wherein a rotary type varying resistor is located to the car body side of a hinge part for rockably supporting a cargo box, and when a hing shaft formed integrally with the cargo box is rotated, a dump angle can be displayed in an angle display unit according to a change in the potential difference of the resistor. CONSTITUTION:When motion of dump is effected, a main switch 22 is turned ON, an expandable cylinder is expanded through control of a control lever. When a cargo box is dumped around a hinge part, an indication needle 14, formed integrally with a rotary shaft 13 located coaxially with the hinge part, is rotated in the direction of an arrow mark. This produces a potential difference between terminals B and C occasioned by a change in resistance 12 of a rotary type varying resistor 10. In which case, a change in a potential difference is displayed as the dump angle of the cargo box according to twist of a confirming gauge 16 of an angle display unit 15 mounted in an operation chamber. This enables easy confirmation of a dump angle as a driver is present in the operation chamber.

Title: Production of toner
Inventor: SATO YUKIHIRO
IPC: G03G9/097
Filed: 1994-05-27
Abstract: PURPOSE:To produce a toner hardly causing variation in amount of electric charge and color unevenness even if the toner having small grain size is produced, hardly causing a deterioration in picture quality due to charge up and high in durability at the time of long-term or continuous use by mixing stepwise each toner material in a mixing stage. CONSTITUTION:In this production method of the toner having a mixing stage of a toner material consisting of at least binder resin, colorant and/or electrostatic charge control agent, each toner material is mixed stepwise in the mixing stage. That is, an unnecessary flocculation between each material and an excessive dispersion of a specified component are eliminated simultaneously as compared to a case at which mixing is executed at a time from the beginning by adding the electrostatic charge control agent and/or the colorant which causes large effect upon toner characteristics at a stage in the midst of the mixing stage or at the latest stage. Therefor, the toner is produced efficiently. A gravity-drop type mixing machine such as V blender and ball mill or high speed flow type mixing machine such as Henschel mixer and supper mixer are used as a device at the time of mixing.

Abstract: PURPOSE:To manufacture the titled brass strip while saving energy by carrying out cold rolling other than final cold rolling at a high draft and the final cold rolling at a relatively low draft and by regulating the grain size by annealing immediately before and after the final cold rolling. CONSTITUTION:When a platelkie brass material is repeatedly subjected to cold rolling and annealing to manufacture a brass strip having a prescribed thickness, cold rolling other than the final cold rolling is carried out at >=60% draft to considerably reduce the number of rolling stages. The grain size is regulated to 10-40mum by annealing immediately before the final cold rolling to accelerate recyrstallization. The final cold rolling is carried out at a relatively low draft such as 40-50% to control the directional properties, and the grain size is regulated to 10-70mum most suitable for deep drawing by annealing immediately after the final cold rolling.

Title: Dc-dc converter
Inventor: MAEDA MIKIO
IPC: H02M3/335
Filed: 1980-08-20
Abstract: PURPOSE:To prevent the concurrent conduction of switchibg element by providing an inductance in series with a resistor in a feedback circuit. CONSTITUTION:Energy is supplied from a conversion transformer T1 to a load side by the ON and OFF operations of the switching elements Q1 and Q2. The inducatance L is inserted in series with a resistor R3 in the feedback circuit constituted by feedback windings nf1 and nf2 and the resistor R3. When the switching element Q1 is turned from ON to OFF, a voltage is induced in the direction so that the beginning of the winding is positive in the feedback winding nf1, and the voltage is applied to the feedback winding nf2 so that the beginning of the winding is positive. The rise of said voltage is slihgtly delayed than that of the feedback winding nf1. Therefore, the rise in a base winding nB2 is also delayed, and the rise of the collector current of the switching element Q2 is also delayed. Thus the concurrent conduction of the switching elements Q1 and Q2 can be prevented.

Title: Color image forming device
Inventor: YOSHINO KUNIHISA
IPC: G03G15/01
Filed: 1986-05-19
Abstract: PURPOSE:To obtain a color image being free from a color shift by an exposure of once, and to easily adjust a color balance by providing two sets of light source units in which three kinds of fluorescent lamps having a light emission energy distribution characteristic which has conformed with a spectral transmittivity of a color separation filter of each color of a photosensitive body. CONSTITUTION:While a drum-shaped photosensitive body 4 makes one rotation in the direction as indicated with an arrow, a color image is formed. That is to say, the surface of the photosensitive body 4 is electrified to a uniform potential by electrifier 5, and to its electrified surface, an image exposing device 6 executes an image exposure by a reflected light from an original D of a radiated light which has used light source units 20A, 20B. In this state, by an operation of an electrifier 16 for executing AC or a DC corona discharge of a code opposite to the electrifier 5, the surface potential of the photosensitive body 4 becomes roughly uniform, and subsequently, by an electrifier 26 being the same as the electrifier 16, the surface potential of the photosensitive body 4 becomes flat entirely. Next, by irradiating uniformly its image exposure surface with a green light obtained by a lamp 7G, a potential pattern for giving a green complementary color image appears on the image exposure surface.

Title: Moving mechanism for core slide in push-button tuner
Inventor: CHIYAKI TAKAO
IPC: F16H25/24
Filed: 1981-07-24
Abstract: PURPOSE:To avoid damage to screws and screw pieces without frequency shift due to play of the screw piece, by constituting the screw piece with an elastic member and forming a slit for switching. CONSTITUTION:A screw piece 11 is made of an elastic member such as synthetic resin and a slit 11B is formed over the entire length axially at the outside. In screwing the screw piece 11 to a screw 10 of a tuning shaft, the screw piece 11 elastically tightens the screw 10 from the outside. Through this constitution, when a tuning shaft is turned, the screw piece 11 is moved along the axial direction of the tuning shaft. In this case, since the screw piece 11 elastically tightens the screw 10 from the outside, no play is produced between the piece 11 and the screw 10. When the piece 11 reaches the end of the screw 10, the screw piece 11 is restricted for the movement, but the screwing between male and female screws 11A of the screw 10 is released, allowing to prevent damages to screw threads.
