IPC: H01J35/22
Filed: 1985-02-20
Abstract: PURPOSE:To improve the throughput of generation of X-rays by installing a plurality of large current sources of pulse and alternately discharging them. CONSTITUTION:A large current source of pulse is composed of the first large current source 21 of pulse consisting of a capacitor 10a and a switch 12a or the like and the second large current source 22 of pulse consisting a capacitor 10b and a switch 12b or the like. When generating X-rays, first, the switches 12a and 12b are closed to simultaneously charge the capacitors 10a and 10b. Next, the switches 12a and 12b are opened, and switches 21 and 22 are put in the A side, respectively, and thus a large current of pulse is supplied from the large current source 21 to generate the X-rays. Following to this, the switches 21 and 22 are put in the B side, respectively, and thus a large current of pulse is supplied from the large current source 22 to generate again the X-rays. Whereby, since it is possible to generate two X-rays against one charging time, the throughput is improved two times.

Abstract: PURPOSE:To allow changing of a focal distance with good accuracy without generating cracking and peeling by crimping an elastic reflecting member which is liquid at a relatively low temp. between a pair of transparent films having stretchability and providing pressure chambers which are variable in pressure and face each other on both sides thereof. CONSTITUTION:The elastic reflecting member 14 has the stretchability and is constituted by airtightly crimping a reflecting film 12 consisting of a light reflective metal which is liquid at the relatively low temp. in the form of a thin film between a pair of transparent films 10A and 10B. The focal distance variable mirror 10 is constituted by having a pair of the pressure chambers 16A, 16B which are formed to face each other on both sides of the elastic reflecting member 14 and are variable in pressure and a pressure change generating part 18 which controls the pressure thereof. For example, mercury or an alloy of sodium and potassium or the like is used as the metal which is liquid at the relatively low temp. and forms the reflecting film 12. An arbitrary focal distance is obtd. in this way when the elastic reflecting member 14 is deformed by the pressure chambers 16A, 16B which are variable in pressure. Since the member has the stretchability, the generation of the cracking and peeling by metal fatigue is obviated.

Title: Dual-timing circuit-type homing device of submerged cruising body
Inventor: TAKEDA NORIFUMI
IPC: G01S15/66
Filed: 1980-03-11
Abstract: PURPOSE:To improve the reliability of homing under dual-timing system by switching the setting of Doppler sampling time depending on the detection of a target echo so that a torpedo, etc. may be put in ''homing mode'' instead of ''search mode''. CONSTITUTION:If a target echo is detected through the intermediary of a Doppler circuit 3 after the sampling by the first timing circuit 5, a switch is changed over to shift a mode from ''search'' to ''homing''. Then the second timing circuit 6 is controlled through a gate circuit 4 and a sampling time is adjusted so that a prearranged timing where the existence of an echo from the target is estimated may be obtained. Thus a homing due to water surfacial reverberation, etc. is prevented, so that the reliability of homing properties of a torpedo, etc. is improved.
