Title: Method and device of generating plate-like plasma
Inventor: IKUTA KAZUNARI
IPC: H01S3/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of external disturbance to an external electronic equipment by irradiating the surface a thermion emissive material of a negative electrode with laser beam so as to form a plate-like plasma mirror with a high-frequency high voltage applied between a negative electrode and a positive electrode. SOLUTION: When the surface 1a of a thermion emissive material of a negative electrode 1 is obliquely irradiated with a laser beam 20, the thermion emissive material surface 1a existing in a thermion emissive area is quickly heated to the thermion emissive temperature. When high voltage is applied between a negative electrode 1 and a positive electrode 2, a plate-like plasma mirror having the same cross sectional shape with the thermion emissive area is formed. A directive radio wave 8 output from a radiation antenna 7 is reflected by the plate-like plasma mirror 4 so as to be a reflected wave 8a, and is directed in a required direction. This reflecting direction is determined by the surface direction of the plate-like plasma mirror 4.  The thermion emissive area, namely, direction of the plate-like plasma mirror 4 is changed by changing the operating position of each output pulse laser, and at the same time, reflecting direction of the reflected electromagnetic wave 8a is changed.

IPC: H02M7/537
Filed: 1993-09-09
Abstract: PURPOSE:To provide a reset circuit which can surely make switching operations by reducing the surge current of the switching element. CONSTITUTION:In a reset circuit in which a series circuit of the main winding 14 of a transformer 13 and a switching element 16 and another serial circuit of the reset winding 15 of the transformer and a reset diode 17 are connected in parallel between DC input power sources, the reset diode 17 is connected so that its cathode and anode can be respectively connected to the plus-side terminal 10 of the input power source and one of end of the reset winding 15.

Abstract: PURPOSE:To shorten the transmission time of the output low/high state of the switching time by sinking the base electric charge of the 4th transistor as the collector current of the 2nd transistor whose base is connected to the emitter of the 1st transistor. CONSTITUTION:When a signal of a high level is supplied to the base of the 1st transistor TR4, the TR4 conducts and then the 2nd TR5 conducts.

While the 5th and 6th transistors TR8 and TR9 conduct when the TR4 conducts and the 3rd tR6 is nonconductive. Thus, a current flows to an output terminal 3 from a high potential power supply terminal 1 via a resistance 15 and the potential of the terminal 3 is set at a high level. In such a way, the TR5 conducts immediately after the TR4 conducts and the base electric charge of the TR7 is extracted.

Filed: 1988-10-05
Abstract: PURPOSE:To obtain a result of measurement with high accuracy in a state that only minute pressure works on the surface of an object to be measured by synthesizing simply lateral pressure of an electric micrometer and spring pressure of a plate spring so as to offset them. CONSTITUTION:When a measuring area of ds+ or -DELTAd1 is set centering around a measuring and comparing origin ds at the time when a standard dimension article is set, DELTAf-DELTAf1 corresponding to DELTAd-DELTAd1 becomes surplus pressure. It becomes the cause of giving damage to the surface of an object to be mea sured, as well. In order to make this pressure small, by integrating an electric micrometer into which an opposed spring is integrated, surplus pressure DELTAf-DELTAf1 can be eliminated. That is, by setting the pressure of the electric micrometer to DELTAf-DELTAf1approx.= electric micrometer, the measurement can be executed by extremely minute pressure.
