Title: Integrated amplifier
Inventor: KOBAYASHI TAKAYUKI
IPC: H03G3/02
Filed: 1984-11-21
Abstract: PURPOSE:To prevent sound quality degrading due to induction and lowering in price and to improve the quality by providing an equalizer amplifier amplifying an input signal, a selector switch, a variable resistor, an attenuator, an operation switch and a high gain power amplifier. CONSTITUTION:The standard input is fed to an auxiliary input terminal 3 of the high gain power amplifier 16, a low level signal fed to a record player signal input terminal 1 is amplified by the equalizer amplifier 2 to be matched to the input standards of the power amplifier 16 and a high level signal fed to a main input terminal 7 is attanuated by the attenuator 12 to be matched with the input standards of the power amplifier 16. The gain of the power amplifier 16 in this case is 43dB being the addition of the gain 18dB of a flat amplifier and the gain 25dB of the power amplifier to obtain an output of e.g., 60W. Thus, the sound quality is improved because the flat amplifier is eliminated and cost-down is attained.

Title: Manufacture of semiconductor integrated circuit device
Inventor: OKAMOTO YOSHIHIKO
IPC: G03F7/20
Filed: 1994-10-12
Abstract: PURPOSE: To efficiently form a pattern by using a positive-type electron beam resist and a negative-type electron beam resist when using only one section of electron beams and two or more sections of electron beams, respectively. CONSTITUTION: A resist material to be used is restricted depending on whether the number of the sectional shapes of electron beams e1 and e2 is one or two in a process for irradiation with the electron beams e1 and e2 to a semiconductor wafer. Namely, when the number of the sectional shapes is one, the drawing area ratio of a connection hole 23 for connecting wire is reduced to 1/2 or less by using a positive-type electron beam resist 21. On the other hand, when an exposure method where the number of sectional shapes of the electron beams e1 and e2 becomes 2 is at least partially used, the positive-type resist or negative-type resist is determined by simply leaving or deleting a region irradiated with the electron beams e1 and e2 .

Title: Wire cut electric discharge processing device
Inventor: ITO TETSURO
IPC: B23H7/02
Filed: 1984-11-26
Abstract: PURPOSE:To improve a processing speed by controlling tension applied to a wire electrode based on a judgement result from inter-electrode judgement means, and preventing the electrode weakened in its tension resistance from being disconnected by reducing the tension upon abnormal while reducing short-circuit by increasing the tension upon normal. CONSTITUTION:Detected troubles such as concentrated electrical discharge or wire disconnection as a result of deterioration of inter-electrode condition as a result of deterioration of inter-electrode conditions, an output is provided to a counter 26, amplified through an amplifier 106, and delivered to a controlling transistor 107 as base voltage. Hereupon, a motor current satisfies:I=Vs/R. It is found from this expression that the current I is controlled by the base voltage Vs, but the Vs is reduced and hence a drive current for a tension motor 100 is reduced to permit wire tension to be reduced, whereby disconnection of the electrode weakened in its tension resistance due to wear of the electrode can be prevented, while the device can securely be allowed to escape from abnormal processing conditions by making use of a fact of current reduction and fact that the device is brought into a non-load due to back movement. Furthermore, with the inter-electrode state being returned to a normal state the tension of the wire electrode is gradually increased, whereby rigidity of the wire electrode is increased with reduced short-circuit for improving the processing speed.
