Title: Darlington transistor
Inventor: KOIKE MICHIMARO
IPC: H03K17/60
Filed: 1987-06-11
Abstract: PURPOSE:To prevent production of a parasitic transistor, by using a Schottky barrier diode as a diode while using a cathode region as a base region of a second transistor. CONSTITUTION:A Schottky barrier diode 14 is provided between a base and an emitter of a second transistor 5. Generally, no minority carrier is injected into the Schottky barrier diode 14 and hence no minority carrier is stored therein. Further, the Schottky barrier diode 14 capable of switching quickly is suitable for high speed operation. Since the Schottky barrier diode 14, unlike other P-N junction diodes, has a metallic component, it has a low threshold voltage and low series resistance and is therefore allowed to have rapid switching characteristics. No parasitic transistor is produced by the Schottky barrier diode 14 formed in a semiconductor, substrate 3 because the Schottky barrier diode 14 has a metallic component.

Abstract: PURPOSE:To completely automate a conveyance from an ejector for empty tray package to a filling and sealing device, by installing a device which piles in stages empty trays for enclosure package, a conveyor for pooling them, and a device which objects the piling-in-stage trays to the filling and sealing device side. CONSTITUTION:A device is constituted such that a device 7, which piles in stages empty trays conveyed after an enclosure package is discharged to a packing device, a pool conveyor 9 for pooling the trays, and a device 20, which ejects one by one the piling-in-stages trays conveyed from the pool conveyor to a filling and sealing device 23, are located between the filling and sealing device 23 and the packing device. This permits the automation of a conveyance from a package ejector 1 for an empty tray 4 to the filling and sealing device 23 side, and besides, the empty trays 4 can be pooled in quantities in a piling-in- stages tray 21 in the conveyor 9 even in case the device 1 is out of order, which results in preventing the empty trays 4 from suspending being supplied and in improving the productivity.

IPC: H01J65/04
Filed: 1995-05-23
Abstract: PURPOSE: To suppress formation of enveloped hot pots by coupling high-frequency power from a source with a splitter. CONSTITUTION: A high-frequency source 20 supplies high-frequency power to a power splitter and a phase shifter 22. The phase shifter 22 supplies the output at the frequency of a container 10 to an electric field applicators AP 12, 14, 16, 18. The phase and the amplitude of the signals to be applied to the AP 12, 14, 16, 18 are selected so as to rotate the electric field to be applied to the container 10 at the frequency of a source 20. In other words, the output of the phase shifter 22 has equal amplitude, and the signals applied to the AP 12, 14 have phases shifted by 180 deg.. Similarly, the signals applied to the AP 16, 18 have phases shifted by 180 deg.. The signals to be applied to the neighboring AP have phase shifted by 90 deg..  Power input to the plasma in the container 10 is carried out evenly in planes by using a rotating electric field and the partial heating effect on the lamp outer coating is lowered, so that arc adhesion phenomenon where hot spots are formed on the lamp wall can be avoided.

Abstract: PURPOSE:To completely remove shear droop produced at first time of punching by shaving even at one time. CONSTITUTION:By using the punching for a first time having a little smaller size than finishing size, an opening hole part 25 having a little smaller size than the finishing size is formed to a metal plate 24. In such a case, at the circumference of the upper surface on the opening hole part 25 of the metal plate 24, the shear droop 26 is formed. Successively, a wedge type punch 27 is pressed into the opening hole part 25 of the metal plate 24 to form a rising part 29 at the circumference of the upper surface on the opening hole part 25. Successively, a flattening punch is pushed to the rising part 29 at the circumference of the upper surface in the opening hole part 25 of the metal plate 24 to flatten the part of the rising part 29. Thus, the shear droop 26 formed at the circumference of the upper surface on the opening hole part 25 of the metal plate 24 by punching at the first time is completely removed. Thereafter, by using the punching for shaving having the size corresponding to the finishing size, the opening hole part 25 of the metal plate 24 is worked to the finishing size.

Title: Method for forming cleavage line of air bag lid part
Inventor: SAITO KAZUHIRO
IPC: B60R21/20
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To reduce the working precision to a cleavage line and improve the durability or weather resistance by forming a hairpin-shaped pressing groove recessed to the reverse side on a surface skin layer constituting an air bag lid part. SOLUTION: A hairpin-shaped pressing groove 1 recessed to the reverse side is formed on a surface skin layer 2 constituting an instrument panel 1, and the bottom part 17 of the hairpin-shaped pressing groove 11 is cut by a cutting tool 16 from the reverse side of the instrument panel 1 to form a cleavage line 6. According to this, a high working precision is dispensed with as in the case of thinning the instrument panel 1 while leaving a part of the surface skin layer 2 to form the cleavage line 6, and the work can be performed with a low working precision. Even if the instrument panel 1 has a dispersion, the cleavage line 6 can be formed without any trouble. Further, the durability and weather resistance can be also improved by cutting the bottom 17 of the hairpin- shaped pressing groove 1 from the reverse side of the instrument panel 1 to form the cleavage line 6.
