Title: Helicopter
IPC: B60R1/06
Filed: 1992-03-12
Abstract: PURPOSE:To secure the rear view of a helicopter by fixing a rear view mirror to the tip of a support device, of which tip can be fixed under the condition that the tip is projected from a fuselage of a helicopter to the forward upward of the fuselage and of which tip can be positioned in forward upward position of the fuselage of a helicopter and can be drawn or turned to be housed in the barrel. CONSTITUTION:A rear view mirror 14 is provided through a movable-type rear view mirror support device 15, which can be projected and drawn to/from the forward upward position of a fuselage 5 of a helicopter. In the case where the rear view mirror 14 is required, for example, in the case of low speed flying such as take-off and landing, the rear view mirror 14 is projected outside of the fuselage 5, and a pilot 9 can confirm the rear view 35. In the case where the rear view mirror 14 is not required, for example, in the case of high speed forward flying, the rear view mirror 14 is drawn to be housed inside of the fuselage 5 so as to be under the housing condition 21. Air resistance can be thereby reduced at the time of high speed flying so as to restrict the deterioration of the performance, and the noise and the vibration can be reduced.

Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain a coating composition capable of forming a membrane maintaining high hydrophilicity for a long time even in a dark place, and useful for prevention of dew condensation, fouling, etc., by including a specific photocatalyst parcels, tungsten chloride and tetrahydrofuran.

IPC: H01J23/20
Filed: 1983-03-29
Abstract: PURPOSE:To prevent the thermal fusion between a frequency-controlling pin and the contact surface of a controlling-pin-supporting groove completely by making the diameter of the portion of the controlling pin corresponding to the supporting groove when the whole body of the controlling pin is inserted in the resonance cavity of an anodic body small so that said portion is slightly apart from the supporting groove. CONSTITUTION:A frequency-controlling pin 18 is connected to a mechanism which can change and control frequency. It is installed in the resonance cavity of an anodic body 4 in such a manner as to be freely inserted into and withdrawn from the cavity and to be slidden on the inner surface of the controlling- pin-supporting groove 3 of a supporting plate 2. The portion of the controlling pin 18 corresponding to the supporting groove 3 when the whole body of the controlling pin 18 is inserted in the resonance cavity, has a small diameter so that it is slightly apart from the supporting groove 3. Owing to the above constitution, any thermal fusion between the controlling pin 18 and the contact surface 3a of the supporting groove 3 of the supporting plate 2 can be prevented.

Abstract: PURPOSE:To measure very precisely a phenomenon wherein the impedance of a measuring element changes at high speed with time, by determining the impedance of the measuring element from the amplification rate of an unbalanced voltage, the amplification degree of a complex voltage and the impedance of comparing elements. CONSTITUTION:The constants R1, R2, R0 and C0 of the comparing elements 24, 26 and 28 of an alternating-current bridge 20 are selected so that the output of the alternating- current bridge approaches zero in the state wherein a coil, which is a measuring element, is placed near to a steel plate, and the outputs of an in-phase component DC amplifier 42 and a rectangular component DC amplifier 44 at that time are measured. Next, a switch 40 is operated by a relay circuit 50 to change the impedance C0 of the comparing element 28 to C0+DELTAC0, and the outputs of the in-phase component DC amplifier 42 and the rectangular component DC amplifier 44 at that time are measured. Then, the switch 40 is returned to its home position by the relay circuit 50 to return the impedance of the comparing element 28 to C0. Next, the coil is scanned along the steel plate and the measurement of a change in the impedance of the coil is started. The outputs of the DC amplifier 42 and 44 are inputted in CPU46. CPU46 computes the impedance of the measuring element 22 immediately and delivers the same as a measured value.
