Abstract: The present invention is directed to method for setting a formed helical compression spring. At the out set, parameters are measured to determine a reaction force axis of a formed helical compression spring. Next, A target reaction force axis of the spring is compared with the reaction force axis determined by the measured parameters to provide an error between the target reaction force axis and the detected reaction force axis. Then, a tilt angle of at least one of the compression plates tilted to an end plane of the spring is provided, in at least one direction on a plane including a coil axis of the spring, on the basis of the error between the target reaction force axis and the detected reaction force axis. Then, at least one of the compression plates is actuated to pressurize the spring, with at least one of the compression plates tilted to the end plane of the spring by the tilt angle.

Abstract: The present invention is directed to an inclined helical spring having a plurality of coils along an inclined coil axis. Each coil constituting a part or the whole length of the helical compression spring is increased and decreased in diameter along the longitudinal axis of the spring, and forming the longitudinal axis of the spring in a free state thereof to be inclined substantially at a predetermined angle to an axis to be mounted with the spring. For example, one section of each coil having approximately a half of the circumference of each coil, which is divided by a plane including the coil axis, is increased in diameter, whereas the other one section of approximately a half of the circumference of each coil is decreased in diameter. The inclined helical spring may be mounted on a vehicle suspension.

Abstract: An uplink channel transmission power control method is provided for a CDMA mobile communication system performing one way communication. A base station measures the received level of data transmitted from each mobile terminal at each channel, and generates a transmission power control signal of each uplink traffic channel. The generated transmission power control signals are multiplexed, and the multiplexed common transmission power control signal is transmitted to all mobile terminals by using the common channel shared by the mobile terminals. Each mobile terminal derives the transmission power control signal of the uplink traffic channel used by the terminal, from the received common transmission power control signal, and controls the transmission power of a data packet.

Abstract: A speed control system for a selection servomotor of an impact printer or the like employs a speed table which represents a series of speed data which are respectively matched with various differences between real and mark positions of a motor shaft. The speed table is stored to be selectively read out when addressed. A difference between real and mark positions of the motor shaft is added to a head address of the speed table, and the sum is used as an initial address for reading data out of the speed table. Thereafter, the speed data are sequentially read out up to the head address in accordance with the rotation of the motor shaft, so that the motor is driven in response to such various data. A plurality of such speed tables are prepared to vary the speed profile in matching relation with a specific initial value of the difference between the real and mark positions of the motor shaft.

Abstract: An impact printing apparatus automatically discriminates the kind of a type element mounted on a reciprocating carriage of the printer and interchangeable with another type element. A print control program is selected in conformity to the specific kind of type element while desired printing is carried out according to the selected program. Each of the interchangeable type elements is provided with a mark or marks or coded data to be detected by a sensor which is located in a predetermined position on a stationary part of the printer. The mark or coded data is sensed while the type element is rotated or while the carriage carrying the type element is moved. A single mark in the form of a slit is formed in a rotary hub of the type element, and the sensor for detecting the mark comprises a light emitting element mounted on the carriage and a light receiving element mounted on the stationary part of the printer which corresponds to the light emitting element.

Abstract: A CRT display screen of a word processor apparatus displays at least one line of characters. The number of characters in the line is variable, and the character size is automatically adjusted so that the lines fill the width of the screen regardless of the number of characters. The number of characters may be selected from several predetermined numbers such as 80, 96, 128 etc. Alternatively, the number of characters may be determined by the right margin position. In the latter case, when the right margin position is leftward of a predetermined character position, such as 80, the characters may be displayed in 80 character line format with blank spaces rightward of the right margin.
