Title: Facsimile equipment
Inventor: EJIRI SEISHI
IPC: H04N1/23
Filed: 1990-02-23
Abstract: PURPOSE:To reduce the consumption of ink by applying capping when a Q signal of a specific kind is received so as to decrease a required number of times of idle discharge. CONSTITUTION:When an EOM (message end) is sent from a sender side in succession to a picture signal PIX, the capping processing of a recording head is implemented. When an EOP (end of procedure) is received in succession to the picture signal PIX, capping is implemented immediately to the recording head to send MCF (message confirmation). When an MPS (multi-page) or EOM (message end) is received in succession to the picture signal PIX and even when a RTN (retaining negation) representing a line defect is sent from the receiver side, capping is implemented. Thus, the capping is implemented quickly in response to the Q signal (MPS, EOM, EOP or the lime) sent from the sender side.

Title: Multi-beam antenna of grid reflection mirror
Inventor: KONDO AKIRA
IPC: H01Q19/17
Filed: 1985-03-04
Abstract: PURPOSE:To improve the identification of cross polarized wave even if a horn is out of focus by setting optimizingly the direction of a feeding electric field as a horn placed at a focus and each horn placed at the outside of the focus. CONSTITUTION:The horn 30 among hours 27-33 is placed at the focus and the others are arranged at the outside of the focus. Further, directions of electric fields 27'-29' of the horns 27-29 have angles theta1-theta3 to the feeding electric field 30' of the horn 30. The relation of the angles theta1-theta3 is expressed as theta1>theta2>theta3. That is, the angle is larger as the respective horn is parted from the focus. Thus, the cross polarized wave component is cancelled as the horn is parted from the focus. Then even when the horn is parted from the focus, the cross polarized wave identification is not deteriorated. Thus, even when the horn is out of focus, the cross polarized wave identification is improved.

Abstract: PURPOSE: To more realistically display a personal image at real time in a presence communication conference system. CONSTITUTION: A person to be displayed is expressed by implicit function elements 48 in addition to a wire frame model 46. The model 46 is deformed in accordance with the movement of the person at real space and the implicit function elements 48 are also moved. When human body parts collide with each other, the collision is detected by the implicit function elements 48 and then the collision is detected also by the model 46. Since the rigidity of corresponding human body parts is applied to respective implicit function elements 48, the implicit function elements 48 are deformed at first when the parts collide with each other and then model 46 is deformed in accordance with the deformation of the elements 48. Consequently the deformation or collision of mulcle can be more realistically reproduced.

Abstract: PROBLEM TO BE SOLVED: To make a handrail wall easily handleable, in addition to an improvement in its workability. SOLUTION: This handrail wall is provided with a half panel 4 attached with a backing ledge 1 tight to the backside of a surface plate 14, and a surface single plate 5 opposedly set up on this surface plate 14 via the-backing ledge 15, and in this constitution, a handrail structure 3 is installed in the end of a floor supported by a floor beam 1, and the backing ledge 15 is locked to this handrail structure 3 so as to make the surface plate 14 of the half panel 4 be set up at one side of this structure 3, attaching the surface single plate 5 tight to the backing ledge 15 after being set up another side of the handrail structure 3.  Thus, the handrail structure 3 is installed in the end of the floor supported by the floor beam 1, and since the half panel 4 and the surface single plate 5 are attached to this handrail structure 3, this structure is no longer installed in the half panel 4 and the surface single plate 5 in terms of constitution, therefore the promotion of lightweightiness in each member can lee thus expedited. Consequently, finishing work is easily performable from both sides after the handrail structure 3 is assembled, so that its workability is well improved, and also, handling work in time of conveyance or the like becomes facilitated.
