Title: Dry developer and its production
Inventor: NISHIKAWA MASAHARU
IPC: G03G9/097
Filed: 1979-05-26
Abstract: PURPOSE: To prevent the excessive charging owing to stirring in the developing device and achieve the stability of image quality by mixing the particles having the material in the position on such a charge array at which the charges of the toners are neutralized when rubbed with the toners at least on their surfaces.  
     CONSTITUTION: The dry-type two-component developer is loaded in the developing device and is stirred by stirring blades or the like in order to maintain an always even state. When the stirring time becomes long upon long-term use, the charging quantity of the toners in the developer increases rapidly, causing the developing characteristics to vary. Although the charging quantity of the toners does not give so much influence upon the reproducing density of characters as shown by the curve A, it causes a large change in the reproducing density of solid portions like the curve B. Thereupon, the particles deposited with the material in the charging array position of neutralizing the friction charging potential of the toners at least on their surfaces are in the dry-type component developer at a suitable amount in correspondence to the state of the developer, whereby the excessive charging of the toners may be prevented as shown by the curves A, B and image quality stabilized.

Title: Petri dish
Inventor: ISONO KEINOSUKE
IPC: C12M1/22
Filed: 1990-03-15
Abstract: PURPOSE:To provide a Petri dish enabling observation using an inverted microscope at relatively increased magnification under easy temperature control of high accuracy, so designed that at least part of a gap-forming means is moved or eliminated when needed and the bottom surface is brought into contact with a flat board. CONSTITUTION:Because a temperature-regulating means 8 and its support 13 are fixed on a stage 16 and for a Petri dish 1, a gap-forming means has already removed, the virtual bottom surface 5 comes into close contact with the temperature-regulating means; thereby resulting in no temperature difference between the inside of the Petri dish 1 and said temperature-regulating means 8, thus enabling temperature control with high accuracy. Also, because the virtual bottom surface 5 comes into close contact with the temperature- regulating means 8, it is enough that the distance between the objective lens 11 of an inverted microscope 9 and the cells to be observed be equal to the thickness for the bottom surface 6 of the Petri dish 1 and the temperature- regulating means 8; that is, said distance may be shortened compared to the case with the presence of the gap-forming means; thus enabling the magnification of the microscope 9 to be increased correspondingly.

IPC: H03G1/00
Filed: 1983-04-15
Abstract: PURPOSE:To control simply the amplification factor of a differential amplifying circuit with no trimming of a resistance which requires a complicated and exclusive device, by attaining the variable setting of constant current value for a constant current source which limits a working current flowing in common to a pair of active elements. CONSTITUTION:A differential amplifying circuit consists of a pair of transistors TRQ1 and Q2 connected with a load resistance RC respectively and a constant current source 10 which controls a working current flowing in common to the TRQ1 and Q2. Plural constant current circuits consisting of TRQ3, Q4... and resistances R3, R4... connected in series to the emitters of said transistors are connected in series to each other to constitute the source 10. Then an optional constant current circuit selected by operation signals e1, e2... sent from outside and supplied to the bases of the TRQ3, Q4... is actuated. Thus the constant current value is set variably. Thus the amplification factor is controlled variably for the differential amplifying circuit.
