Title: Antenna unit
Inventor: YAMAWAKI SEIICHI
IPC: H04B7/185
Filed: 1978-10-11
Abstract: PURPOSE:To make effective use of the antenna for artificial satellites, by enabling to set narrow emission region to one of transmission and reception waves, through the possibility of independent detemination of the power ratio shared to each emission element with the provision of the phase shifter. CONSTITUTION:The signal transmitted from the transmitter 1 is divided into two at the hybrid 3A, and the signal passing through the circulator 4T is received for the phase shift by phi in total through the reciprocation of the phase shifter 5T and  it is given to the hybrid 3B. But the signal passing through the circulator 4R is  not subjected to the phase shift but merely passed through 4R to the hybrid 3B. On the other hand, the reception signal inputted to the emission elements 8A and 8B externally is subjected to the pahse shift of phi' in total in the phase shifter 5R with reciprocation as to the signal passing through the circulator 4R, but not for the signal passing through the circulator 4T. Since the phase shifts of phi and phi' are caused independently of each other from the separate phase shifters 5T and 5R, independent control can be made.

Filed: 1987-05-23
Abstract: PURPOSE:To form non-welded parts between the base part of the mount part molded product of a medical bag and two plastic sheets, by mounting the base part of the mouth part molded product of the medical bag to a core pin whose leading end is covered with a non-conductive material and subsequently sandwiching said base part between two plastic sheets to press and weld the same by a mold. CONSTITUTION:The base part 4 of the mouth part molded product 3 of a medical bag is mounted to a core pin 1, whose leading end is covered with a non- conductive material 2, so as to be overlapped with the non-conductive material 2 within a range of 2-5mm and subsequently held between two plastic sheets 5, 6. This holded part is further clamped by molds 9, 10 having sheet pressing parts 7, 8 straightly formed thereto to be welded to form non-welded parts between the base part 4 and the plastic sheets 5, 6. As a result, no welding burr is generated in the internal space of the sheets 5, 6 and a stable and strong bag nice to look at can be supplied. Since the non-welded parts are closely adhered between the sheets 5, 6 and the mouth part molded product 3, the penetration amount of a liquid to said closely adhered parts becomes very small.

Abstract: PURPOSE:To improve reliability in judgement of unmeasurableness by latching a signal of a detecting system for fine detection in synchronizing with a signal of another detecting system for rough detection, and comparing it with the previously latched pulse value. CONSTITUTION:When the measurement of a detecting system 2 for fine detection is not reliable due to an overspeed or the like, first of all, a pulse value of the detecting system 2 latched by a latch circuit 17 in response to the first passage of a reference signal track 13 of another detecting system 3 for rough detection is stored in a storage circuit 18. Next, a main scale 6 and an index scale 7 both are relatively shifted toward an arrow A, and the pulse value of a pulse signal out of the detecting system 2 is counted by a counter circuit 16, while the latch circuit 17 reads the pulse value of the detecting system 2 in synchronizing with a light receiving signal 14 out of a light emitting element 8 in a corresponding position of the track 13 and feeds it to an arithmetic circuit 19, comparing it with the previously stored pulse value. Then, if a difference between these two pulse values is a value corresponding to a difference in the adjacent track 13, it is so judged that the detecting system 2 is performing a reliable measurement aright.

A cell image signal whose image is formed with the sensors 6 and 10 by a sensor drive signal generated with a two-dimensional drive circuit 11 is applied to computing circuits 12 and 13 of optical systems A and B to extract a contour of a signal of the cell image thereby judging the circle of the image. As cell images measured from specified two directions are identical in shape as for a sphere with a cell wall removed by a proper processing, the cell involved is judged to be suited to a cell fussion 6.
