Abstract: PURPOSE:To form a copied image of a stable density by counting the continuous generation time of a toner supply signal and switching a supply quantity per unit time from a hopper to a developing device to the second supply quantity if this signal is generated continuously for a prescribed time. CONSTITUTION:Before copying of an original, a standard black plate 19 is illuminated by a lamp 2, and an electrostatic latent image corresponding to the black plate 19 is developed by a developing device 20. The quantity of reflected light of the formed toner image is measured by a reflected light measuring circuit 22; and if this measured quantity is higher than a preliminarily set quantity of light, the circuit 22 sends a signal of a mode I to a DC servomotor driving circuit 23. The continuous generation time of the signal of the mode I is measured by a counter 24; and if this measured time exceeds a preliminarily set time, the signal is switched to a signal of a mode II, and this signal of the mode II is sent. The voltage applied to a DC servomotor 25 is controlled by the circuit 23 to control the supply quantity of toner due to a supply toner 12. Thus, a copied image of a stable density is formed.

Title: Composite type switch circuit
Inventor: ICHIJO MASAMI
IPC: H03K17/567
Filed: 1985-10-14
Abstract: PURPOSE:To prevent a current from flowing to a base, collector equivalent diode by connecting a diode to a base and a collector of a BiMOS circuit and forming a bias circuit connected in parallel between the base and source. CONSTITUTION:When an on-control signal is impressed while a current flows to a diode 6 in an inverter circuit, a carrier stored in the base/collector equivalent diode of a transistor (TR) 1 is discharged and a loss is caused. In this case, diodes 7, 8 are connected to the base and collector of the TR 1. Since the current from a current supply source 9 flows almost via the diode 8, no excess carrier is stored in the diode between the base and collector. Since a bypass circuit 100 is made unidirectional, no current flows from the source to the base via the bypass circuit and no current flows to the equivalent diode from the source. Then in applying the title circuit to an inverter circuit, inconvenience such as short-circuit of a DC circuit is avoided.

Abstract: PURPOSE:To enable the assay of oxygen at a high accuracy with a high sensitivity with a simple separating operation, by combining a chemical separation of fluorine-18 formed in the nuclear reaction of oxygen-16 and helium-3 with a double-stage distil separation and an insufficient equivalent precipitate separation. CONSTITUTION:Helium-3 is made to irradiate a reference sample containing gallium arsenide and the known amount of oxygen and a fluorine carrier is added to prepare a sample solution. The fluorine containing fluorine-18 generated with the irradiation of helium-3 is separated by a double-stage distillation as silic on fluoride with perchloric acid and silicon dioxide from an analysis sample solution. Then, a partial fixed amount of the fluorine-18 is separated by insufficient equivalent precipitation as lanthanum fluoride with lanthanum nitrate aqueous solution. Then, the assay of oxygen can be done at a high accuracy with a high sensitivity by comparing the radioactivity of the fluorine-18 separated by the insufficient equivalent precipitation from the radioactivity of the fluorine-18 thus obtained and the reference sample solution in the same way with the analysis sample solution.

Filed: 1985-10-16
Abstract: PURPOSE:To always function the center of reel pressing force applied downward by a spring on the center line of a reel, by attaching a spring and a reel cap which is pressed by said spring at the reel side. CONSTITUTION:A reel cap 36 and a spring 42 are attached at the side of a reel 24 and therefore moved horizontally together with the reel 24 even in case the reel 24 has a horizontal position shift within a cassette housing 23. Thus both the cap 36 and the spring 42 never get out of the center line P1 of the reel 24. Thus it is possible to apply the reel pressing force F2 produced downward by the spring 42 correctly on the line P1 at all times in an exactly same way as a non-application more even if the reel 24 has a horizontal position shift within the housing 23.
