Title: Microwave branching filter
Inventor: ITO YOSHIO
IPC: H04B1/40
Filed: 1987-03-25
Abstract: PURPOSE:To instantaneously change the frequency of a channel to be used, by providing the serial body of a switch and a BPF between corresponding circulators of first and second circulator strings respectively, and performing the ON-control of only one switch. CONSTITUTION:The microwave of the channel (CH)3 inputted from an input terminal 17 is almost totally reflected by the switch 21 set at an OFF state via the circulator(CL)1, and inputted to the CL1 again. An output from the CL1 is supplied to the switch 22 set at an ON state via the CL2, and it passes through the switch, then, it is inputted to the BPF30. A signal passing through the BPF30 is inputted to the BPF31 via the CLs 10 and 11, however, since the BPF31 corresponds to the frequency of a CH5 and no influence is given on the frequency of the CH3, the input signal is almost totally reflected on the BPF31, then it is inputted to the CL11. The signal is introduced to the BPF32 of a CH7 via the CL12, but, similarly it is almost totally reflected, and is supplied to the CL12. The signal, after receiving total reflection by the switches 25-28 respectively, arrives at an output terminal 18.

Title: Astable multivibrating circuit
Inventor: TERAI HARUO
IPC: H03K3/0231
Filed: 1979-06-05
Abstract: PURPOSE:To enable to change the ON and OFF time of the output according to the change in the power supply voltage, with shorter ON-OFF time when the power supply voltage is greater and smaller time when smaller. CONSTITUTION:When the power supply is fed, the capacitor 4 is charged through resistors 5 and 6. When the charging voltage increases to the reference voltage V1, the output of the comparator 3 is ON and it decreases to the ground potential. Then, the charging current of the capacitor 4 is bypassed and the discharge path is formed with a resistor 12, capacitor 4, diode 7 and comparator 3. In this case, the diode 11 is back-biased. Accordingly, even if the input voltage V2 of the comparator 3 closes to zero voltage, the voltage waveform at the discharge of the capacitor 4 is not fallen gradually, but linearly into V2. When the voltage of the capacitor 4 reaches V2, the reference voltage of the comparator 3 increases to V1.

Abstract: PURPOSE:To obtain sufficient heat resistance to the repetition of high temperatures or a momentary abnormally high temperature by storing plural optical fibers with a protection coating loosely in a heat-resisting pipe, and providing a protection layer of fiber-reinforced thermosetting plastic around the pipe. CONSTITUTION:Plural optical fibers 2 with a protective coating are stored in the heat-resisting pipe 10 so that a gap 11 is left in it, and the protection layer 5 made of fiber-reinforced thermosetting plastic is arranged outside of the pipe. The plural optical fibers 2 are bundles and the buffer protection layer 3 is formed of silicone rubber or fluororubber in one body to obtain a coated bundle 4 which has a nearly circular section. The pipe 10 is formed by impregnating a paper tape, etc., with thermosetting plastic and then setting the plastic. The gap of the bundle 4 and pipe 10 is so determined that D>=1.04d, where (d) is the external diameter of the bundle 4 and D is the internal diameter of the pipe 10. Consequently, even when this unit is exposed repeatedly at high temperatures in windless summertime or a momentary abnormally high temperature of about 400 deg.C due to, for example, a thunderbolt, there is no cracking generated in the protection layer 5 and this unit is usable for OPGW (optical composite overhead earth-wire), etc.

Title: Temperature controller
Inventor: MORII SHIGEHIRO
IPC: G05D23/24
Filed: 1980-05-30
Abstract: PURPOSE:To prevent chattering just after application of a power supply by prohibiting, until a fixed DC voltage is obtained immediately after the application of power supply, an inflow of a current to a switcing circuit. CONSTITUTION:Just after application of a power supply, during charging a capacitor 7, even if an amplifier 8 oscillates, bias resistances 18, 19 of a transistor 20 does not conduct before a regular voltage with a voltage-regulator diode 6 is obtained. Therefore a relay coil 3 does not conduct and chattering does not occur at all. With such constitution, the width of hysteresis can be reduced, thus providing a temperature within the chamber such as expressed by a temperature curve B and improved accuracy.
