Title: Implantation of high-dose ions
Inventor: HORI MINORU
IPC: H01L21/266
Filed: 1984-03-02
Abstract: PURPOSE:To etch easily after the ion implantation and to eliminate adverse effect to a semiconductor water, by employing as an ion blocking mask a laminated structure which consists of a metal film having a larger ion-stopping power as an upper layer and a photo resist film being difficult to contaminate the wafer as a lower layer. CONSTITUTION:After a photo resist film 5, a metal film 6, and a photo resist film 7 are sequentially laminated, an opening 8 is formed in the photo resist film 7. When the metal film 6 within the opening 8 is etched away using the resist film 7 as a mask, and the resist film 7 and the resist film 5 within the opening 8 are removed by plasma-etching using oxygen, an ion blocking mask which consists of laminations of the resist film 5 and the metal film 6 and which has a common opening 8 are formed on the wafer. Thereafter, high dose ions are implanted near the opening 8 to form an ion-implanted area 9 on the wafer surface. However, the high dose ions irradiated on the metal film 6 are blocked by the film 6, only to form a very shallow ion-implanted area 10 on the surface.

Title: Receiving system with elimination of disturbance wave
Inventor: KAISHIMA MAKOTO
IPC: H04B1/10
Filed: 1981-03-19
Abstract: PURPOSE:To faclitate the easy elimination of the disturbance wave, by setting three receiving antennas to ensure the same phase and same amplitude at an equal distance to the desired wave and then synthesizing the received signals. CONSTITUTION:Antennas 1a-3a are set with an equidistance (d) in order to secure the same phase and same amplitude at an equal distance to a desired wave 11. In case a disturbance wave 12 and the wave 11 are received with an angle theta formed between them, the receiving phase difference of the wave 12 is different between antennas 1a/2a and 1a/3a. The degree of control is calculated from the relation between the synthesized output of the antennas 1a and 3a plus the disturbance wave component of the antenna 2a. Based on this degree of component, the amplitude is controlled for the output of the antenna 2a. At the same time, the output of the antenna 2a receives a phase shift of 0 deg. or 180 deg. in accordance with the arriving angle theta of the wave 12 and is synthesized with the outputs of antennas 1a and 3a. In such way, the disturbance wave can be eliminated.

Title: Frequency dividing circuit

IPC: H03K3/288
Filed: 1982-03-16
Abstract: PURPOSE:To execute a stable operation by a low voltage power source, by constituting a titled circuit so that a load of a master flip-flop (FF) circuit in a frequency dividing circuit is used as a constant-current source, and also a trigger is supplied to the master FF from its constant-current source. CONSTITUTION:For instance, in case when a transistor (TR)Q4 of a slave FF part B is off, and a TRQ5 is on, a TRQ3 and a TRQ2 become on and off, respectively, and become a saturated state. A current iA and iB from a constant- current source of TRs Q6, Q7 are further increased, a voltage drop of a resistance R4 exceeds VBE4 of the TRQ4 consequently, the TRQ4 becomes on, and simultaneously, the TRQ5 becomes off from on. In that case, the operation of the TRQ2 and Q3 is not inverted but holds its state as it is. Subsequently, as time of a trigger pulse to a terminal P passes, a current of the TRs Q6, Q7 becomes ''0'', and when the current iA and iB start to flow again as time further passes, the TRQ2 becomes on, Q3 becomes off (Q4 and Q5 become on and off, respectively) in reverse to above phenomenon, and this operation is repeated.

Abstract: PURPOSE:To certainly perform the transfer of a liquid globule even when the liquid globule exposes the lower end of a transfer tip element by making the angle of the transfer tip element to a surface to be transferred smaller than the angle formed by the tangential line passing through the lower end of the transfer tip element and having the contact point with the surface of the globule nearest to the surface to be transferred and the inclined transfer trip element. CONSTITUTION:A liquid globule 3 is bonded to the lower end part 20b of an inclined transfer tip element 20 so as to expose the lower end 20c thereof. At this time, the angle theta of inclination of the transfer tip element 20 to a surface 30a to be transferred is made smaller than the angle formed by the tangential line L passing through the lower end 21c and having the contact point with the surface 3a nearest to the surface 30a of the liquid globule 30 to be transferred among the tangential lines abutting on the surface 30a and the transfer tip element 20. Therefore, when the lower end 20c comes into contact with the surface 30a to be transferred, the surface 3a of the liquid globule 3 comes into contact with the surface 30a to be transferred before the lower end 20c comes into contact with the surface 30a to be surely transferred.
