Title: Fixing metal fitting
Inventor: KAWAGOE AKIKATSU
IPC: F16B37/10
Filed: 1991-04-19
Abstract: PURPOSE:To rapidly attach and detach a member to be fixed such as a projector to and from a member on a stationary side with ease by forming a screw portion in either one of an insertion hole formed in a supporter, into which a screw shaft is inserted, and a closing groove formed in a cap member separably connected to the supporter. CONSTITUTION:In order to fix a projector 7 to a member 9 on a stationary side, a cap member 8 is first separated outward a supporter 3 on a supporting pin 82, and a screw 81 of a closing groove 8A formed in the cap member 8 is separated from a screw shaft 4. Subsequently, the screw shaft 4 is moved upward at one moment along an insertion hole 3 formed in the supporter 3, and first and second receiving plates 2, 5 are brought into contact with the member 9 on the stationary side. And then, the closing groove 8A is closingly fixed in such a manner that the screw portion 81 is screwed to the screw shaft 4. A slight operation by fine adjustment for fastening the screw shaft 4 allows the receiving plates 2, 5 to be held in the member 9 on the stationary side, to thus secure the projector 7 to the member 9 on the stationary side. Consequently, the number of screwing operations of the screw shaft 4 can be reduced.

Title: Injection synchronous oscillator
Inventor: OGISO KOUJI
IPC: H03B5/18
Filed: 1978-09-22
Abstract: PURPOSE:To avoid the lowering in the output power by the circulator insertion loss and the increase in the injected power, by giving the injected synchronizing signal from the gate terminal of FET. CONSTITUTION:The micro strip lines 17 and 18 are connected to the tip of the micro strip line 5, and the reference signal generator 11 is connected to it.

The micro strip lines 8, 9 and the matching circuit 7 are adjusted so that the oscillation frequency fo can be obtained without injection signal. When the signal is injected from the micro strip line 18 to the gate terminal 3 of FET 1, since FET 1 has amplification operation, greater level than the injection level is appeared at the gate terminal 3 of FET 1. Further, no signal separation is required at the output side, the circulator is not necessary.

Filed: 1982-07-06
Abstract: PURPOSE:To improve the accuracy of detection in a micro flow rate region by cutting off the frequency components above the frequency at which Karman vortexes are generated in the micro flow range among the output components of a vortex detector provided on the downstream of a vortex generator. CONSTITUTION:A comparator 19 compares the output from an electric power amplifier 7 and a prescribed reference voltage, and opens or closes a switch 20 connected in parallel with a resistor 16. If the output from the amplifier 7 is lower than the comparing voltage, that is, in a micro flow rate range, the output of the comparator 19 is at a zero level and the switch 20 is opened; therefore, a low-pass filter 5 keeps functioning. When the output from the amplifier 7 rises to the comparing voltage or above, that is, in the stage of a high flow rate, the comparator 19 closes the switch 20 to short circuit both terminals of the resistor 16; therefore, the filter 15 does not function and the output signal of the amplifier 7 passes through the same as it is.
