Title: Primary winding current limiting circuit in igniter
Inventor: SUGIURA NOBORU
IPC: F02P3/05
Filed: 1979-03-20
Abstract: PURPOSE:To prevent the limiting circuit from oscillating by changing a set point of primary winding current applied current limitation in response to the fluctuation of power supply voltage in a current limiting circuit to limit the current to be flowed to primary windings of ignition coils below a settled valve. CONSTITUTION:In a current limiting circuit, potential of a collector C in a transistor Tr14 is affected by the fluctuation of power supply voltage, even though base B current is constant, thereby the current of collector emitter CE increases and decreases. As this current grows larger than its necessity, conduction degree of a Tr15 is increased with output Tr200 off, to cause oscillation in the current limiting circuit. However, when current of said CE is increased, voltage to be returned to a resistor R154 is also increased and with increase of conduction degree of Tr33, current to be flowed to the base is decreased. In consequence, in the rise of power supply voltage, to which in response detecting level of the Tr14 is sent up, the set point will be sent up against current values set in the beginning of current limitation at the time of normal voltage values.

Abstract: PURPOSE:To increase a frequency of an ultrasonic vibration applied to a tool and to improve cutting efficiency with vibration amplitude of a tool being increased by fixing a propagation medium, whose sectional area of an ultrasonic vibrator side is made larger than the tool side sectional area, in one row to the ultrasonic vibrator. CONSTITUTION:A balancer 13 is provided at the left side of a longitudinal vibrating ultrasonic vibrator 1 and plural propagation mediums 4 propagating ultrasonic wave via an electrode 2 are provided at the right side. The propagation mediums 4 are formed larger than the sectional area 4b of the tool 5 side at the part of the sectional area 4a of the vibrator 1 side either and a tool 5 is fixed to the end face 4b of the right side propagation medium 4. So the vibration amplitude amplified is propagated to the tool 5 side even in case of the vibration amplitude of a vibrator 1 being small because of the vibration amplitude of the larger side of the sectional area 4a being amplified and enlarged and appearing at the small side of the sectional area 4b, the vibration frequency of the vibrator 1 is made higher and the vibration amplitude of the tool can be made larger, and a high working efficiency is obtained.

Abstract: PROBLEM TO BE SOLVED: To send a substitute reply in response to a position of a cordless slave set automatically to a caller by storing in advance substitute reply information corresponding to position registration information and allowing a voice storage means to output the substitute reply information selected based on the stored position registration information at the arrival of an incoming call. SOLUTION: Each guidance for a substitute reply with respect to an incoming call from a zone (office) 4a and a zone (conference room) 4b of radio connection devices 2a, 2b is stored in advance in a storage means 13. When a slave set 3 moves to the zone 4a or 4b, a radio management means 12 stores automatically position registration information P to the means 13 based on the information P from the device 2a or 2b. When the slave set 3 receives an incoming call, a main control means 11 informs the incoming call to the save set 3 and a guidance control means 15 via the means 12 and the device 2a or 2b. The means 15 reads the information P of the slave set 3 from the means 13 and allows a voice storage means 14 to send a guidance of a corresponding substitute reply. Thus, the substitute reply corresponding to the position of the slave set 3 is sent automatically to a caller.

Title: Printer
Inventor: HASHIMOTO KENICHIROU
IPC: B41J2/32
Filed: 1981-03-09
Abstract: PURPOSE:To provide a printer which realizes a low noise without higher mounting accuracy of a print head and a platen with a behavior given to stop at a given position by a spring member while the platen is pivoted so as to turn freely. CONSTITUTION:For example, a platen 11 is fixed on a plane of a cylindrical platen holder 10 after it is formed by cutting one surfce thereof and pivoted with a shaft 12 in such a manner as to be free to turn in the direction of the arrow. This holder 10 has the gravity thereof matching the shaft 12 with the platen 11 fixed so that it can be at rest at any angle about a shaft 8. One end of a coil spring 13 is fixed opposite to the mount surface of the platen 11 and the platen 11 is given a behavior to elastically stop at the position where the inclination thereof becomes the same that of a print head 3. This spring 13 allows the holder 10 to be retained at such a position that the platen 11 will always contact in the plate satisfactorily with the print head 3 ignoring external force to be applied. Thus, any gap between the two components can be absorbed to eliminate chattering. EFFECT:This permits a low mounting accuracy of the platen and the print head.

Abstract: PURPOSE:To allow each equipment to receive a transmission signal of all equipment by using a light of a different wavelength for the transmission from a master node equipment to a sub node equipment, the transmission from the sub node equipment to the master node equipment and the transmission between the sub node equipments, mixing the light once in a star coupler and distributing the result to each equipment. CONSTITUTION:A signal from the master node equipment 1 and the signal from the sub node equipment 2 are both inputted to a port of the same side of the star coupling 3. Then an output from the other port is returned to both the master node equipment 1 and the sub node equipment 2. The star coupler 3 is installed near the sub node equipment 2. Furthermore, lights of different wavelengths lambda1, lambda2 are used for the transmission for the master node equipment 1 and the sub node equipment 2. Thus, even if the both make transmission at the same time, no signal collision takes place. The star coupler 3 mixes once the transmission signals and then distributes the result to each equipment. Then each equipment receives the transmission of all the equipment including itself.
