Filed: 1989-05-09
Abstract: PURPOSE:To prevent the disturbance of communication due to the influence of a rotor blade of a helicopter by switching plural antennas attached to the upper part of the helicopter body synchronously with the rotation of the rotor blade. CONSTITUTION:The antennas 1A and 1B attached to the upper part of the body of a helicopter 11 are connected to an antenna switch 2 which is controlled by the synchronizing signal received from a rotation synchronizing signal detector 4 of a rotor blade 12 of the helicopter. The radio waves switched by the switch 2 are supplied to a radio transmitter/receiver 3. Then the signals of both antennas 1A and 1B are switched synchronously with the rotational cycle of the blade 12. At the same time, both antenna 1A and 1B are attached at the positions where a phase shift is produced so that the antennas 1A and 1B are not shielded by the blade 12 at one time. Thus a fixed synthetic output wave is secured between both outputs of antennas 1A and 1B. As a result, the communication is never interrupted.

Filed: 1994-05-30
Abstract: PURPOSE:To realize strong stretching using sea water regardless of the depth by injecting sea water through a pump into a soft pipe fixed with a plurality of transceivers thereby inflating the pipe. CONSTITUTION:When an array type transceiver 5 is sunk, an ON/OFF valve 3 in a bypath 8 is opened to equalize the pressure in a silicon pipe 4 to the outer hydraulic pressure. Upon receiving a stretch starting signal externally, a control circuit circuit 1 closes the ON/OFF valve 3 to inject sea water through a pump 2 into a pipe 4 fixed with a plurality of transceivers 5 housed in a box 7 thus inflating the pipe 4 and stretching the transceivers 5 along with a signal line 6. Consequently, the pressure of the soft pipe 4 is equalized to the outer hydraulic pressure and the capacity of the pump 2 can be made constant regardless of the depth. Furthermore, when the transceivers 5 are entangled upon injection of sea water, rotational direction of the pump 2 is controlled to telescope the pipe 4 thus stretching the transceivers normally.

Title: Manufacture of semiconductor device
Inventor: OGAWA YOSHITO
IPC: H01L21/60
Filed: 1985-05-30
Abstract: PURPOSE:To produce a great number of elements in one semiconductor wafer by a method wherein beam leads are formed protruding toward each other from neighboring element regions on a wafer and piled one upon another with a polymide resin layer between. CONSTITUTION:A number of element regions 2 are formed separated from each other on a semiconductor wafer 1. From each of the element regions 2, beam leads 5, 6 are lead out along the upper surface of the wafer 1. Thereafter, portions not mounted with the element regions 2 are removed by etching for the formation of semiconductor devices provided with beam leads 5, 6 protruding outward from the sides of the element regions 2. In this process, the beam leads 5, 6 protruding toward each other between neighboring element regions 2 on the wafer 1, are piled one upon the other with a polyimide resin layer 7 between the beam leads 5, 6. For example, the first layer beam lead 5 is formed to be entirely coated with the polyimide resin layer 7 provided by application. The polyimide layer 7 is removed by etching with some retained to cover a part of the beam lead 5. The second layer beam lead 6 is then formed to be positioned on a part of the first layer beam lead 5 with the intermediary of the polyimide resin layer 7.

Title: Mos operation amplifying circuit
Inventor: NAKADAI HIROKO
IPC: H03K5/02
Filed: 1986-05-23
Abstract: PURPOSE:To increase the speed and the gain with low current consumption by providing a load MOSFET of the second conductive type having a relatively low conductance and a MOSFET of the second conductive type made temporarily operatred which are formed into a current mirror and increasing the current supply capability of a differential amplifying circuit or an output circuit at the change timing of a signal. CONSTITUTION:A timing signal phi is temporarily set to the low level synchronously with the change timing of an input signal Vin. Then, MOSFETs Q5 and Q6 are turned on at the time of signal change to relatively increase the resultant conductance of steady loads MOSFET Q3 and Q4. Since the differential amplifying circuit has a relatively high current supply capability when the input signal Vin is changed, the change speed of an output signal Vout is increased. Then, MOSFETs Q5 and Q6 are turned off, and the load of differential MOSFETs Q1 and Q2 is reduced to a relatively low conductance due to MOSFETs Q3 and Q4, and therefore, the gain is increased.

Title: X ray diffractometer
Inventor: EGAMI KOUJI
IPC: G01N23/20
Filed: 1981-07-27
Abstract: PURPOSE:To prevent possible of scattering of X ray and unwanted diffraction thereof from a sample holding means by employing a sample holding means made up of a monocrystalline substrate whose main surface is oriented by such an angle as to exceed the angle resolution of an X ray diffractometer from a desired crystal face. CONSTITUTION:An incidence X ray 9 emitted from the X ray focus 2 on an X ray anticathode 1 enters a sample 12 via a divergent slit 3. Here, the sample 12 held with a sample holder 4 is turned at a rate of theta per unit time on the center 5 of rotation while a counter 8 for measuring the strength of diffracted X ray is turned at a rate of 2theta per unit time on the center 5 of rotation. Consequently, depending on the crystal structure peculiar to the sample 12, the strength of the diffracted X ray increase near the angle to meet a specified diffraction requirement and is recorded as peak on the X ray chart. Here, the main surface 13 of the sample holder 4 made up of a monocrystalline substrate is oriented by a desired angle from a desired crystal face 14. This eliminates unnecessary diffraction peak thereby enabling the collection of data better in the signal-to-noise ratio.
