Title: Zoom lens
Inventor: HORIUCHI AKINAGA
IPC: G02B15/16
Filed: 1989-12-11
Abstract: PURPOSE:To obtain a zoom lens having simple constitution which has a 2.0 F number, an about X8 variable magnification ratio, and high optical performance over the entire power variation range and consists of a relatively small number of lens elements by selecting properly lens constitution such as the lens shapes and refracting powers of the respective lens groups of the four-group zoom lens. CONSTITUTION:The zoom lens is equipped with four lens groups, i.e. a 1st group I for focusing which has positive refracting power, a 2nd group II which has a variable magnification function and negative refracting power, a 3rd group III which compensates an image varying owing to variable magnification and has negative refracting power, and a 4th group IV which has an image forming function and positive refracting power in order from the object side. Then, an inequality I holds, where Fi is the focal length of an (i)th group, and FT, FNOT, and omegaT are the focal length of the whole system at the telephoto end, the open-aperture F number, and the half angle of the field respectively. Consequently, the four-group zoom lens has the high optical performance over the entire variable magnification range while aberration variation caused by variable magnification when the about 2 F number and about X8 high variable magnification ratio are obtained with the small number of lens elements are compensated excellently.

IPC: H04B1/20
Filed: 1993-12-21
Abstract: PURPOSE: To prevent the number of stations of a local communication system from being restricted by the number of data channels, while the advantages of the system, namely, its simple constitution and inexpensiveness are maintained. CONSTITUTION: A local communication system is provided with a large number of interconnected stations 101-109 for communicating multiplex control messages and a control channel is divided into eight parallel channels Ch0-Ch7, which are used in such a way that any seven channels of the eight channels receive messages from the station assigned to the remaining one channel. The message for each channel is subdivided into limited message units. At the time of receiving a long message, a receiving station prevents the message from being received by the other channels, until the reception of the message ends. In order to make the number of stations larger than that of data channels, a certain station is made to be used commonly with a single channel for transmitting control message by setting the station as 'slave only'.  In order to prevent collisions, transmission is only performed, in response to request messages.
