Title: Liquid developer for developing electrostatic latent image
Inventor: WATANABE HARUO
IPC: G03G9/12
Filed: 1987-12-26
Abstract: PURPOSE:To improve the electrostatic charge of a coloring agent and to provide the higher speed of development and the higher grade of an image by adding fine particles of metal oxides further to a liquid developer prepd. by dispersing the coloring agent into a carrier liquid having an electrical insulating characteristic. CONSTITUTION:The coloring agent is dispersed into the carrier liquid having the electrical insulating characteristic and the fine particles of the metal oxides are added thereto. The fine particles of the metal oxides essentially consisting of SiO2, Al2O3, PbO2, MgO, etc., and the metal oxide mixture composed thereof are usable as the fine particles of the metal oxides. The high-grade image having high resolution are thereby formed and the sufficient coloring density is obtd. even by high-speed development. The collapse of the image, etc., arising from the flow of the coloring agent particles in the development process are thus prevented.

Title: Telephone system
Inventor: TAMURA YOSHIHIKO
IPC: H04M1/72
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a ringer incoming from being transmitted to a control means even when a ringer detecting circuit executes erroneous detection as the ringer incoming due to noise by using the output of a branch monitoring circuit as the control signal of a second switching element directly. CONSTITUTION:When any one of telephone sets goes to an IN USE condition, a branch monitoring circuit 2 detects this condition and the output is caused to be an 'H' level. Since a diode D5 goes to be non-conductive, the potential voltage of a voltage dividing circuit rises up and a transistor Q4 is turned on. Then, an LED D4 is turned on. Since the transistor Q4 is turned on during the IN USE, the emitter of a transistor Q3 is led through a diode D3 into a GND and the transistor Q3 is turned off. Accordingly, even when the ringer detecting circuit executes the erroneous detection the noise which is generated in a line in case that a self-pulse or the other telephone set is changed from an OFF HOOK to an ON HOOK, the signal of the ringer incoming is not sent to a CPU.

Filed: 1988-12-29
Abstract: PURPOSE:To ensure detection of the runaway of a microprocessor by detecting abnormality and resetting the microprocessor if the value of a counter which the displacement or position of a printing head receiving an output signal from a signal generating circuit reaches a specified value. CONSTITUTION:A microprocessor 2 receives a printing command, a specified timer value is set in a signal generating circuit 3 so that the circuit 3 starts counting. If the circuit 3 finishes counting of the set timer value, it connects an output signal to a counter 4 and the microprocessor 2. A counter 4 increments a counter value receiving the output signal, and the microprocessor 2 drives a carrier motor 1, moving a printing head by one step to the right. If the microprocessor runs away, and the value of the counter 4 reaches a specified value, that is, the displacement of the printing head reaches a value which exceeds a displacement from an extreme left end to an extreme right end, an abnormality is detected by an abnormality detection circuit 4 and the microprocessor 2 is reset.

Filed: 1992-11-17
Abstract: PURPOSE:To obviate the necessity of a power source and transfer a large number of persons by connecting and disconnecting a connecting mechanism by the opening/closing of a door and the weight of the passengers. CONSTITUTION:When a person gets on an elevator and closes a door 14, an engagement/disengagement mechanism 16 connects a connecting mechanism 10, and a power transport passage 9 leading to a locking mechanism 7 is connected, and the locking mechanism 7 is released through the power transmission passage 9 from an interlocking mechanism 13 by operating an operating member 12 in a box body 6. Though, when the locking mechanism 7 is released, the box body 6 is lowered by the weight of the person, the excessive increase of the lowering speed is prevented by a rise adjusting means connected with a flexible condition 4 suspending the box body 6. When the box body reaches an escape floor, an auxiliary locking mechanism 11 operates, and the power transmission passage 9 is cut off by releasing the connecting mechanism 10, and since the box body 6 is locked with a guide rail 2, the rise of the box body 6 in the case where the person gets off the box body is prevented. Accordingly, the necessity of a power source is obviated, and a large number of persons can be transferred spoedily at one time.

Title: Rotary compressor
Inventor: TANAKA TAIGA
IPC: F04C18/356
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To reduce outflow quantity of oil from a compressor by enabling an inside refrigerant passage and an outside refrigerant passage to allow the passing of a compressed refrigerant by opening on the both ends of the rotor shaft direction, and covering an opening of the inside refrigerant passage and an opening of the outside refrigerant passage with an oil separating plate. SOLUTION: A refrigerant compressed by a compression element incorporated inside a compressor rises inside a rotor 4a by passing through a refrigerant passage 10 and a magnetic flux separating groove. The refrigerant flows out of an opening of a refrigerant outflow port 15 and the refrigerant passage 10. At this time, since an oil separating plate 9 is installed so as to cover the opening of the refrigerant outflow port 15 and the refrigerant passage 10, both refrigerants passing through the refrigerant passage 10 and the magnetic flux separating groove strike on the oil separating plate 9 to separate the refrigerant and oil. Outflow quantity of oil to the compressor outside can be effectively reduced by improving an oil separating effect by the oil separating plate 9.
