Title: Buried gate type gate turn off thyristor
Inventor: HAYASHI YASUHIDE
IPC: H01L29/74
Filed: 1981-08-27
Abstract: PURPOSE:To facilitate the manufacture without deteriorating characteristics, by relatively enlarging the slit width of a P2<+> which forms a gate layer by dispersion arrangement in a P2 layer of a P1-N1-P2-N2 four layer structure and then eliminating the P1 or N2 layer opposed to the center thereof. CONSTITUTION:A high density impurity layer P2<+> is dispersion-arranged as a buried gate in the P2 layer of P1-N1-P2-N2 four layer structure resulting in the enlargement of the width (d) of the slit S1. A part S2 is provided wherein the layer P1 located immediately under the center of the slit S1 is eliminated. The part S2 wherein the P1 layer is eliminated does not operate as a thyristor but  as a transistor N1-P2-N2 in an element thickness direction. Therefore, when turn-off of the element it comes to an off-state simultaneously with the turn- off of a GTO thyristor part, and an off-characteristic is not deteriorated. Thus, the minumum gate arc current can be reduced without increasing turn-off times.

A text editor row display output part 24 prepares a command for displaying the calculated test pattern row at a display part and outputs it to a text editor. Only the test pattern row corresponding to the specified time in a simulated result is inverted and displayed at the center of the display part.

Title: Manufacture of copper film
Inventor: HASHIMOTO NOBUHIRO
IPC: C23C14/34
Filed: 1986-06-12
Abstract: PURPOSE:To improve the adhesive strength of a Cu vapor deposition film to a glass substrate, by incorporating specific amounts of Al to a Cu target to be used at the time of vapor-depositing Cu onto the glass substrate by sputtering. CONSTITUTION:At the time of applying vacuum vapor deposition to the surface of a glass substrate by the use of Cu as a target, direct vapor deposition of Cu onto the glass substrate surface is liable to cause peeling between the Cu vapor deposition film and the glass substrate surface. At this time, by the addition of 1-10wt% Al to Cu as target, the adhesive strength of the Cu vapor deposition film to the glass substrate surface is improved with the increase in Al quantity. However, if Al is added by >=10%, solubility to etchant as well as surface reflectance of Cu vapor deposition film is deteriorated. If the above defects are not related, adhesive strength can be remarkably increased by adding Al to Cu by >=10wt%.

Title: Umbrella valve
Inventor: KAINUMA MASAKUNI
IPC: F16K15/14
Filed: 1995-06-01
Abstract: PURPOSE: To give relief function to an umbrella valve so as to dispense with a relief valve in particular by forming a recessed part allowing movement of an umbrella shaped part and relief passages communicating across a partition wall at this time, when pressure over a fixed value acts in the direction of pressing the umbrella shaped part of an umbrella valve body on the partition wall side having communicating holes. CONSTITUTION: When back pressure P' lower than a fixed value is applied to an umbrella valve body 20, an umbrella shaped part 21 is pressed to the surface of a partition wall 12 so as to obstruct back flow. Meanwhile, when positive pressure P is applied to the back of the umbrella shaped part 21 through communicating holes 16 and relief grooves 15, the umbrella shaped part 21 is elastically deformed so as to open a flow passage. When back pressure over the fixed value is applied to the umbrella valve body 20, a thick wall part 22 on the center part of the valve body 20 is pressed to the position sinking in a tapered recessed part 13, the umbrella shaped part 21 is elastically deformed along a tapered inner wall 13a, and the end parts of the relief grooves 15 covered with the part 21 are opened. Consequently a relief passage by the relief grooves 15 and the communicating holes 16 is communicated, so as to allow fluid to pass through.

Abstract: PURPOSE:To eliminate the effect of the signal featuring an odd-multiplication of 19kHz by providing the voltage control oscillator circiut, the phase comparator circuit with the 19kHz pilot signal and the trap featuring the frequency of an odd- multiplication to the pilot signal. CONSTITUTION:The input signal to be supplied to FM stereo demodulator circuit 7 processing other signals in the odd-multiplication frequency component (for example, 57kHz) of the pilot signal of 19kHz is supplied to switching circuit 1 as well as to phase comparator circuit 2 via 57kHz trap circuit 8.
