Title: Dry etching method of compound semiconductor
Inventor: TAMURA HIDEO
IPC: H01L21/3065
Filed: 1984-03-28
Abstract: PURPOSE:To improve reproducibility, and to increase a selection ratio with a mask of a photo-resist, etc. and an etching rate by using a mixed gas of BCl3 and Cl2 as a reactive gas employed for reactive ion etching. CONSTITUTION:When total gas pressure is brought to 0.06Torr and high-frequency power to 0.42W/cm<2> by using a reaction gas in which Cl2 is mixed with BCl3 by 20vol%, the time (lag time) when AlGaAs is not etched is not generated owing to the removal of an Al oxide layer formed on the surface after the starting of etching. That is, the oxide-layer removing capability of the reactive gas is increased, and the controllability and reproducibility of the depth of etching are improved largely.

Title: Conductor piece
Inventor: AIDA HIROSHI
IPC: H01Q15/24
Filed: 1983-04-01
Abstract: PURPOSE:To shield not only an electromagnetic wave in the form of horizontally polarized wave but also an electromagnetic wave in the form of vertically polarized wave by insulating a propeller-shaped conductor piece and a conductor piece used in common to a counter weight by means of an insulator. CONSTITUTION:The 2nd conductor piece 4 in common use to the counterweight is provided to a part 2 corresponding to the center of gravity of the 1st conductor piece 1 having propeller structure and also the insulator 5 is inserted to a connected part between the conductor piece 1 and the counter weight 4. Since the 2nd conductor piece 4 in common use to the counter weight is directed always downward vertically in throwing the conductor piece in air, the conductor piece 1 turns around the part 2 being the center of gravity of the conductor piece 1 within a horizontal plane to shield the electromagnetic wave from a Doppler radar or the like, irradiating the electromagnetic wave of the horizontally polarized wave. Since the conductor piece 4 is insulated to the conductor piece 1 by means of the insulator 5, the electromagnetic wave from a radar radiating the electromagnetic wave of the vertically polarized wave is also shielded.

Title: Index generating device for unifying candidate selection
Inventor: NAKASE AKIHIKO
IPC: G06F17/30
Filed: 1988-03-14
Abstract: PURPOSE:To maintain high selecting performance even when the number of variables contained in a term is large by making the presence probability of 1 where the hash value of a function element does not overlap with the hash value of the argument of the function element larger than that where they overlap with each other. CONSTITUTION:When terms are represented as function elements [term 1, term 2 ... term (n)], bit fields of hash values (h) of the function elements are divided into a 1st field F1 which does not overlap with an array of hash values (h) (term 1) - (h) [term (n)] of the terms 1-(n) as arguments and a 2nd field F2 which overlaps with them. Then the presence probability of a bit 1 in the 1st field F1 is denoted as alpha and the presence probability of the bit 1 in the 2nd field F2 is denoted as beta; and then hash value conversion parts 21 and 31 are so set that alpha>beta. Consequently, even when an object term contains many variables, the resolution of the function element does not decreases and an index which is superior in the selecting performance of a unifying candidate term is generated.

Title: Method and device for production of magnetic recording medium
Inventor: MIYAMOTO KAZUYUKI
IPC: H01F41/20
Filed: 1984-03-28
Abstract: PURPOSE:To secure high coercive force and high output by forming a magnetic layer on a substrate with cobalt and a rare earth element used as primary components and so as to show the magnetic anisotropy in a prescribed direction with the function of a magnetic field. CONSTITUTION:An evaporation source 3 containing cobalt 2 and another evaporation source 5 containing a rare earth element 4 are put independently of each other within a bell jar 1 serving as a vacuum tank. The source 3 is heated by an electron beam 7 radiated from an electron gun 6; while the source 5 is heated by an AC power supply. Then the evaporation materials given from both sources are led onto a substrate 9 set at an upper part by opening selectively a shutter 8. At the same time, an electromagnet 10 set around the substrate 9 generates an even magnetic field in the intra-surface direction (an arrow head 11, for example) of the substrate 9 by a DC power supply. Thus a continuous magnetic thin film 15 is formed in a desired composition ratio.

Title: Integrated logical circuit
Inventor: IZUMISAWA HIROYUKI
IPC: G06F11/22
Filed: 1980-05-06
Abstract: PURPOSE:To simplify a simultation model and a logical test device and shorten the time of generation for a test data, by synchronizing the asynchronous input of an FF circuit in a test of a logical circuit. CONSTITUTION:In case a logical device including an FF circuit is modeled into a combined circuit by a logical test device and then simulated, a test indication is  given to an input line 3 and the logical value of the line 3 is changed from 0 to 1. As a result, the input lines 66 and 86 of a master latch 9 and a slave latch 10 are cut off from the asynchronous control signal applied from an input line 4 or 5. Thus the asynchronous control signal changes immediately an output 28 to logical value 0. However, in case the timing of this change is equal to the logical value 0 of the clock, the latches 9 and 10 latch the output 28 before a change of a selector 7 until the output changes again to logical value 0 after the end of supply of logical value 1 in the next timing of the clock. As a result, the asynchronous control signal is delayed until the time when the clock changes to logical value 0 from 1 to be synchronized.
