Title: Potential sensor
Inventor: YAMADA HIROAKI
IPC: G01R29/12
Filed: 1981-02-13
Abstract: PURPOSE:To enable removal of the effect of suspended substances such as dust without changing the performance of the potential sensor by covering a detection hole in a case with a metal plate insulated from the case by an insulator. CONSTITUTION:The detection hole provided at the case 1 is covered with the metal plate 10 through the intermediary of the insulator 9. When an electric flux line 7 strikes at the metal plate 10 and causes an electric charge on the surface of the metal plate, a charge having the same amount with the above and a different mark is caused also on the back surface of the plate, since the plate is a conductor and is suspended by the insulator not to make the charge flee outside. And, the charge at the back surface of the metal plate radiates the electric flux line, which is traversed by the tip part of a tuning fork 2 to which a piezoelectric ceramics 6 for driving is bonded and detected by a detecting electrode 3. According to this constitution, the detection hole can be covered without giving any effect on the detecting characteristic of the potential sensor and thereby a fear of entry of dust and the like inside the sensor is eliminated.

IPC: H01R43/08
Filed: 1980-02-21
Abstract: PURPOSE:To manufacture the commutator having a uniform dimensions by a simple method and to fix the commutator bars rigidly, by manufacturing a cylinder having a tapered parts at both ends by compressing metal powder, forming a bearing part with a resin, and by machining slits on the cylinder part in the axial direction. CONSTITUTION:The conductive inner cylinder 2 having tapered parts 1 on both ends are formed by compressing the metal powder. The resin 3 is filled in the hollow inside of said cylinder 2 and cured, and the bearing part is formed. At the same time, the outer periphery of the tapered parts 1 at both end are convered by the resin. Thereafter the slits that reach the bearing part 3 are machined on the cylinder part 2 in the axial direction, and the cylinder 2 is separated. Thus, the commutator bars 2a-2c are formed. In this method, the commutator having the uniform dimensions are simply manufactured. Since both ends of the commutator bars are embedded in the resin, they are fixed rigidly.

Filed: 1991-02-13
Abstract: PURPOSE:To provide a deodorant having excellent and durable deodorizing effect, comfortable to use and effective for decreasing unpleasant body odor such as armpit smell, foot smell and sweat smell. CONSTITUTION:The deodorant having the above effect can be produced by adding a substance exhibiting buffering action at pH 3-5.5, e.g. lactic acid-sodium lactate, citric acid-disodium phosphate and tartaric acid-sodium tartrate at a concentration of usually 0.01-1wt.% (preferably 0.05-0.3wt.%), thereby adjusting the pH of the deodorant to 3-5.5. The buffering agent may be used as it is, however, it is preferably used by dissolving in water or a solvent such as water- ethanol. The deodorizing effect can further be improved by compounding the agent with an oil-absorbing polymer such as an acrylate copolymer having the structural unit of formula I and formula II (R is 1-30C straight or branched- chain alkyl or alkylene) and a porous vinyl polymer produced by polymerizing and poromerizing one or more vinyl monomers having a solubility parameter of 7-10.

IPC: B41J19/18
Filed: 1993-02-08
Abstract: PURPOSE:To prevent ink to be ejected at a place which is not predetermined by provid ing a power supply stop means that stops power supply to a DC motor based on a generated signal of a signal-generation means, an adequate range stop judgement means that judges stopping range of a recording head based on the generated signal of the signal-generation means or a generated pulse of a pulse-generation means and a means for controlling the recording head based on the judged result. CONSTITUTION:At a time point (1), a motor control signal is turned to a high level to start activating of a DC motor 15 so that a recording head 2 starts its movement. In response to the movement, an ejecting position detection signal is generated in such a manner that a photosensor of an ejecting position sensor 19 which is disposed so as to nip an encoder slit 21a, turns on or off. After the head 2 started movement, an ejecting start position detection signal turns a high level at a time point (2) and turns low level at a time point (3) in accordance with the length of a slit of an encoder plate 25. Assuming that the number of pulses of the ejecting position detection signal until a carriage stops is R and pulses of both ends are (a) and (b) respectively, when the relationship of them is (a)<=R<=b, a CPU judges that the carriage stopped in an adequate range of stopping position.

Filed: 1989-01-30
Abstract: PURPOSE:To enable stable image formation from the startup of development by supplying toner onto a toner carrier and starting development while applying an electric field between a conductive base and a toner conveyance quantity control member when the development is started. CONSTITUTION:The surface potential developed by toner when the toner is supplied onto the toner carrier 9 while the electric field is applied between the conductive base 10 and toner conveyance quantity control member 12 rises as the electric field between the base 10 and member 12 increases. When the toner which is charged electrostatically is supplied to the toner carrier temporarily by an insulating layer 11 on the base 10, the quantity of electrostatic charging is held, but when development is not performed for a long time, the quantity of electrostatic charging varies, so that the development characteristics at the startup of the development become unstable. Here, the toner is supplied onto the carrier 9 in above state at the startup and when the development is started to hold the quantity of electrostatic charging of toner is held constant and the stable development is performed immediately.

IPC: G01N33/569
Filed: 1985-02-05
Abstract: PURPOSE:To solve the cause of food poisoning by rapidly and accurately measuring the enzymatic activity of the labelled antibody bonded or unbonded to a carrier, by reacting an enterotoxin-containing solution with an anti-enterotoxin antibody insolubilizing carrier and an enzyme labelled anti-enterotoxin antibody. CONSTITUTION:Bacteria, for example, a staphylococcus is cultured and purified staphylococcus enterotoxin A is obtained from the supernatant of the culture medium. A rabbit is immunized with this enterotoxin A to obtain anti-enterotoxin anti-serum from which an anti-enterotoxin antibody is, in turn, obtained. Thereafter, this antibody is bonded to an inert carrier to obtain an antibody insolubilizing carrier while said antibody is labelled, for example, by a peroxidase marker to obtain a labelled antibody. A food causing food poisoning is homogenized with a physiological saline solution and the homogenate is centrifugally separated to obtain a supernatant. The antibody insolubilizing carrier and the labelled antibody are simultaneously or separately reacted with the obtained supernatant to measure the activity of the marker of either one of the labelled antibody bonded to the insolubilizing carrier or the unbonded labelled antibody. The measured value is compared with the standard obtained from a specimen with known enterotoxin concn. to know the concn. of enterotoxin in the specimen. By this method, measurement is enabled rapidly and accurately with high sensitivity.
