Title: Semiconductor etching liquid, etching method, and gaas surface check method
Inventor: KITANO TOSHIAKI
IPC: H01L21/338
Filed: 1994-03-09
Abstract: PURPOSE:To change etching speed depending on a substance to be etched and obtain an etching liquid with a noticeable selectivity by adding a base substance to an organic acid/hydrogen peroxide mixed liquid solution and then adjusting the pH. CONSTITUTION:When citric acid is used as organic acid and the volume ratio of circuit acid aqueous solution and hydrogen peroxide liquid solution is set to 100:1, GaAs and AlGaAs can be selective etched within a range of pH6.0-8.0 by further adding a base compound, for example ammonium, to it for adjusting the pH. Namely, within the pH6.0-8.0 range, GaAs can be etched greatly and AlGaAs may not be etched almost at all. Namely, by performing etching to the double structure of n<->AlGaAs layer 1 and n<+>GaAs layer 2 with the above liquid with the resist 3 as a mask, only the n<+>GaAs layer 2 can be etched and the etching can be completely stopped at the n-AlGaAs layer 1.

Title: Magnetic head
Inventor: KUGIMIYA KOICHI
IPC: G11B5/23
Filed: 1988-02-19
Abstract: PURPOSE:To improve the wear resistance of a magnetic head and to reduce sliding noise and noise caused by a false gap by forming most of the surface which is brought into contact with a tape of the magnetic core of polycrystalline ferrite and using a soft magnetic metallic material to the sections adjacent to and in the vicinity of the gap section only. CONSTITUTION:Of the magnetic core of a magnetic head, most of the surface which is brought into contact with a tape is formed of polycrystalline ferrite 3 and a soft magnetic metallic material 2 is used to the sections adjacent to and in the vicinity of a gap section 1. Moreover, a false gap processing layer 4 is provided on the boundary between the polycrystalline ferrite 3 and soft magnetic metallic material 2. Since the grain boundaries contained in the ferrite 3 material effectively erase sliding noises and the soft magnetic metallic material 2 which is used to the sections adjacent to and in the vicinity of the gap 1 produces little sliding noise, sliding noises are hardly produced as a whole and, in addition, formation of a deteriorated layer is prevented by means of the false gap processing layer 4. Therefore, while this magnetic head uses the ferrite having an excellent wear-resistance sliding noise and noise caused by a false gap can be reduced.

Filed: 1992-02-25
Abstract: PURPOSE:To manage accurate and automatic network configuration with respect to a repeater by allowing each repeater to store a sender address from other repeater connecting to its own port. CONSTITUTION:A command packet to recognize a master/slave relation of repeaters connected in cascade is sent by a command transmission reception section C, a repeater receiving the command packet recognizes it that the repeater is connected to a port receiving the command packet and a sender address of the repeater is stored in a storage section M and the command packet for return is generated and sent and the repeater receiving the return command packet recognizes it that the repeater is connected to the port receiving the reply command packet and stores the result to the storage section M. Since it is not required to store all the sender addresses, the address information latched by the repeater is minimized and the capacity of the storage section M is saved.
