IPC: H01Q3/34
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To realize an efficient antenna system which controls the beam directivity without using a rotary joint. SOLUTION: First dielectrics which are arranged like a circle or a regular polygon on one face of a grounded conductor plate 3 and are loaded in the front of element antennas 1 which radiate radio waves to the space by the feed power passing a power distribution circuit 2 are so formed that their planar shapes are a circle or a regular polygon and their sections are Fresnel or taper; and thereby, radio wave from element antennas 1 have phases controlled and are concentratedly radiated in one direction, and dielectrics 5 are only rotated by a motor 4 to vary the beam direction. Radio wave reflection from surfaces of first dielectrics 5 is reduced by projecting parts 6 which are formed on these surfaces so as to have about 1/4 wavelength.  Instead of projecting parts 6, second dielectrics 6a having a low dielectric constant may be laminated on surfaces of first dielectrics 5 so as to have the thickness of about 1/4 wavelength.

Title: Torque limiter for printer
Inventor: AKIYAMA TADASHI
IPC: B41J33/52
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts constituting a torque limiter by a method wherein a pulley vane rotating by being fitted to an ink reel on a feed side of an ink cassette is rotated by being fitted to a slip base, and an elastic body is interposed between the pulley vane and the slip base. SOLUTION: An ink cassette is fitted to a printer so that its joint part is pushed on a pulley vane 502. Thereby the vane 502 is pushed on a disk part 7 side to give a specific displacement to a spring 9, and a sawkerf surface of the disk part 7 is pushed on a felt 4. At the same time the vane 502 is urged toward an ink reel. When an ink sheet is wound on the reel under this state, the vane 502 is rotated by fitting to the reel, and a slip base 501 starts rotation. At that time frictional resistance occurs between the sawkerf surface and the felt 4, and a slip torque is generated to the vane 502. The torque becomes rotational resistance of the reel to give a specific tension to the sheet.

IPC: H02H3/44
Filed: 1987-10-23
Abstract: PURPOSE:To improve the reliability of a protecting operation by enabling the sure prevention of a constant operation at the time of frequency variation through discriminating between operation and non-operation by the use of a specific equation as an algorithm. CONSTITUTION:The algorithm indicated in the equation I is operated in a microcomputer 6 to discriminate between operation and non-operation. In case of a fundamental frequency, the second term of the equation I is zero directly after an accident, and the characteristic of said equation is as shown in the drawing. Also in case of frequency variation, the first and second terms of the equation I take the same value when there is no accident in a system. Therefore, a constant variation does not occur and the characteristic of said equation is as shown in the drawing. On the other hand, the true variation  I of a current absolute value has the characteristic of the equation II, and when the fundamental frequency is f0 and the current frequency is f and the cycle conversion value of alpha is beta, there is established the equation III. Therefore, the constant operation at the time of frequency variation can be prevented surely.
