Title: Dry etching
Inventor: ARIKADO TSUNETOSHI
IPC: H01L21/3065
Filed: 1987-03-26
Abstract: PURPOSE:To prevent a gate oxidizing film from being broken by etching and to enable the formation of a fine pattern, by making magnetic field intensity set at 400 gausses or below in the vicinity of a surface of a cathode. CONSTITUTION:A magnetic field is supplied from an anode 16 side to a cathode 12 side so that magnetron discharge is generated by interaction of the magnetic field to a cathode effect voltage. Thereupon the magnetic field supplied from the anode 16 side is distributed to be largest in gaps formed between magnets and to be small on the magnets. The larger the magnetic field grows, the more steep this distribution becomes to reduce discharge, however, a large potential difference is generated between a magnetron discharge region and a normal glow discharge region and this potential difference causes a current to flow inside a wafer 13 and to break a gate oxidizing film 32. When the magnetic field intensity on a surface of the cathode 12 is set at 400 gausses or below, the potential difference becomes small to much reduce the breakage of the gate oxidizing film 32. Hence, the gate oxidizing film 32 can be completely prevented from being broken or so, and so this film is applicable to a variety of element formation processes.

Title: Magnetic recording and reproducing device
Inventor: TOBA AKIRA
IPC: G11B15/087
Filed: 1986-03-31
Abstract: PURPOSE:To eliminate the discontinuity of a horizontal synchronizing signal by storing a reproduced output of the N-th track (N is a positive integer) from a detected track and providing a duty varying means changing the duty of a control pulse of the stored track in forward running when a semiconductor memory is used for one speed shot reproduction.

Title: Current detecting circuit
Inventor: KITANO JIYUNJIROU
IPC: H04Q3/72
Filed: 1984-04-13
Abstract: PURPOSE:To detect a current with a high accuracy in a simple circuit constitution by connecting bases of two transistors Trs to each other and short-circuiting the collector and the base of one Tr and connecting the emitter of the other Tr to a current detecting resistance. CONSTITUTION:If DC amplification factors of Trs Q3 and Q4 are sufficiently high, most of the current of a constant current source IB is flowed to the collector of the TrQ3. When the value of the current IB is selected to be a value near an actual use range of a detection current IS, collector currents of Trs Q3 and Q4 are equal to each other approximately. When Trs having the same characteristics are used as Trs Q3 and Q4, their forward voltage drops between bases and emitters are equal to each other approximately. Consequently, emitter potentials of Trs Q3 and Q4 are equal to each other, and therefore, the detection current IS outputted from the collector of the TrQ4 is accurately proportional to a load current IL, and its proportional coefficient is given by a ratio of a main resistance RA to a current detecting resistance R3.

IPC: F04D29/44
Filed: 1979-06-11
Abstract: PURPOSE: To reduce the noise, by increasing intake area of only the section of an intake decreasing in pressure with increase of air outlet, and by controlling increase of air volume of the section, whereby wind velocity distribution and pressure surrounding a fan's outside circumference and the intake can be equallized.  
     CONSTITUTION: In order to make opening range of the air outlet 2 of a casing 3 larger than the ideal shape, θ=75° centering a rotary shaft of a fan 1 is increased to approximately 100°. And as to a range which decrease in pressure of an intake 4 with increase in opening range of the air outlet 2 of the casing 3, it is the right- top range (in the sketch) which is the closest to the air outlet 2, and by cutting off this section 5 somewhat larger than other sections, opening area of this section 5 is increased. By using this mechanism, increase in air volume in this section 5 is controlled. As a result, wind velocity distribution and pressure surrounding outside circumference of the fan 1 and the intake 4 are equallized, and therefore, noise is largely reduced.
