Title: Image forming device
Inventor: FUJIWARA YOSHIYUKI
IPC: G03G21/00
Filed: 1990-03-19
Abstract: PURPOSE:To prevent malfunction(erroneous correction) by controlling so that an image forming action can be performed only when plural developing devices previously set are attached. CONSTITUTION:A control part 40 detects whether or not a main developing device 2 and a sub developing device 3 are attached and allows a copying mechanism part 46 to act only when both the developing devices 2 and 3 are attached. When either of the devices is not detected, the mechanism part 46 is not actuated. Then, the control of toner concentration is performed only when the two developing devices 2 and 3 are attached. Thus, the control is standardized and the correction in a state where two developing devices are previously attached is performed to the data on a detected value, so that the malfunction(erroneous correction) is prevented.

Title: Inter-system signal connecting system
IPC: H04L12/40
Filed: 1992-03-26
Abstract: PURPOSE:To mutually transmit a signal between systems S1,S2 in which plural boards of open collector output are connected to buses A1, A2. CONSTITUTION:The buses A1, A2 of the systems S1, S2 are provided with bus extension boards C1, C2, and they are connected by a cable.

Title: Small-sized power storage device
Inventor: YAMAGUCHI KIYOSHI
IPC: H01F6/00
Filed: 1987-03-25
Abstract: PURPOSE:To enable the title device to be mounted on transport facilities by surrounding a superconducting coil for power storage with a superconductor so as to trap the magnetic field generated by the superconducting coil in the inner space, thereby preventing the magnetic field from largely affecting other equipment. CONSTITUTION:The power storage section is comprised of a superconducting coil 2 and a permanent current switch 3. To put a power into the superconducting coil 2, the power supply terminals are connected to terminals 5, 5, the permanent current switch 3 is opened, and a switch 4 is closed. When the current of the superconducting coil 2 reaches the rating value, the permanent current switch 3 is closed, and the switch 4 is opened. Whereupon, a desired energy is stored in the superconducting coil 2 in the form of a magnetic field energy. Since a superconductor 1 has full diamagnetism and exists so as to surround the superconducting coil 2, the inner magnetic field does not leak out of the superconductor 1. If this device is provided with a weight and size which allow it to be mounted on transport facilities such as ships, automobiles and aircrafts, it can be used as the power supply or power source of those transport facilities.

Title: Heat developeble color photosensitive material
Inventor: TAKAHASHI OSAMU
IPC: G03C8/40
Filed: 1985-04-02
Abstract: PURPOSE:To form a heat-developable color photosensitive material low in the min. density in the light, superior in color separability, and raw stock storage stability by forming a layer contg. photosensitive silver halide and specified 2 kinds of compds. on a support. CONSTITUTION:The layer formed on the support contains photosensitive silver halide and the compds. represented by formula A and I, and the compd. of formula A lowers the density in the light of a transferred image, that is, the min. density, and greatly improves discrimination. Main factors of coloring in the min. density part is considered to be in that the oxidation product (having quinone structure) of a color developing agent, being intrisically immobile, reacts with various kinds of additives present in the film, and their decomposition products, and it is partially converted into an easily mobile type, and attached to the dye fixing layer. Presumably, the compd. of formula A preferentially reacts with the oxidation product of the color developing agent as compared with the additives,such as bases, to convert it into a less mobile type, and it can effectively lower the min. density.
