Patent JP-S6454200-A (JP)
Title: Guided missile
Inventor: KATAYAMA MASAYUKI
IPC: G01S13/91
Filed: 1987-08-26
Abstract: PURPOSE: To obtain a large turning performance by turnably providing an air intake cylinder perpendicularly to an airframe axis and providing pressure slots at upper and lower surfaces of the cylinder and pressure leads and a driver of the cylinder in the airframe. CONSTITUTION: When an attack angle is changed so that a lower surface pressure P2 of an air intake cylinder 1 becomes higher than an upper surface pressure P1 , both the pressures P1 , P2 are transmitted to a pressure sensor 5 via pressure leads, its difference is converted into an electric signal, which is in turn transmitted as a command to a driver 7. The driver 7 rotates the cylinder 1 around a rotary shaft 3 according to the command. When the cylinder 1 is rotated along a direction of a speed vector V2 of an air flow, the pressures P1 , P2 of the upper and lower surfaces of the cylinder 1 become equal. Thus, the command to the driver 2 is eliminated so that the cylinder 1 is stopped at the position. As a result, a front surface area of the cylinder 1 to the air flow is held the same as that at the time of the attack angle of 0 deg..  Thus, since a flowing air amount to a propulsion unit 2 is not changed and a propulsion force is not lowered as well, a large turning performance can be obtained.

Title: Semiconductor integrated circuit
Inventor: NAGAMINE HISASHI
IPC: H01L27/088
Filed: 1990-08-10
Abstract: PURPOSE:To absorb noise and static electricity applied between output terminals by providing a protective circuit composed of an n-channel transistor between different power lines. CONSTITUTION:A protective circuit 30 is provided between two isolated power lines. The protective circuit includes an n-channel MOS transistor Tr1, of which gate and drain are connected with a GND2 line 11 while source is connected with GND1 line 4. If noise at several kilovolts is applied between an external output terminal 13 and a grounded external terminal 6, a current flows to the terminal 6 through the MOS transistor Tr1 and MOS transistors Tr2 and Tr6. If the external terminal 13, instead of the terminal 6, is grounded, then punch- through occurs in the MOS transistor Tr1, resulting in conduction from GND1 to GND2. This prevents the gate oxide of the transistor Tr1 from breakdown due to noise or static electricity.

IPC: G21K5/00
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To easily and accurately detect the damage of an ion beam vacuum discharge window by obtaining the film thickness and composition of the window from the energy distribution of particles scattered from the window. SOLUTION: When a hydrogen ion (proton) beam having an energy of 1.5MeV is, for example, converged to the width of about 50μm, passed through a discharge window using a polyimide film having a thickness of 7.5μm from vacuum and taken out into oxygen gas at about 1atm, the proton scattered from the window is detected by a semiconductor particle detector disposed in the direction of about 150 degrees with respect to the advancing direction of the beam to obtain its energy distribution. Then, the composition and film thickness of the window are examined from the distribution by a Rutherford back-scattering(RBS) method, and the damage due to the ion beam emitting is detected. Thus, the fracture period of the window can be predicted without interrupting the ion beam emission, and the damage of the apparatus due to the fracture of the window can be prevented.
