Title: Doping method using irradiation with electron beam
Inventor: WADA TAKAO
IPC: H01L21/263
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To prevent the irradiation damage caused by piecing of high-energy electron beams through a semiconductor substrate. SOLUTION: A dopant base material 12 having an element to be doped is superposed on the substrate 11 and the dopant base material 12 side is irradiated with the electron beams at an acceleration voltage at which the electron beams stop in the dopant base material 12. The dopant base material having the thickness (d) in the irradiation direction of the electron beams larger than the electron beam advance distance (d) within the dopant base material 12 expressed by d=Rex/ρ (where Rex is a projection range, ρ is the density of the dopant base material) is used as the dopant base material 12 to be used at this time. As a result, the substrate 11 is prevented from receiving the damage by the electron beams with which the substrate is irradiated.

Title: Discharge lamp lighting device
Inventor: NOGUCHI AKINOBU
IPC: H05B41/24
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To prevent drop of the output of an inverter circuit even in the course of a long period of service. SOLUTION: If the output voltage of an inverter circuit 2 has dropped in the course of a long period of service, the voltage of a fluorescent lamp FL rises owing to its negative characteristics. The voltage charged on a capacitor C23 is increased, a zenor diode ZD11 is turned on so that a current flows to a resistance R24, and the voltage of the gate of PUT Q12 rises to result in turning-on, and a light emitting diode LED11 emits light. This turns on a photo- transistor PTr11 and causes shortcircuiting of a resistance R14, and the voltage dividing ratios of a variable resistor R12 and a resistance R13 are varied.  The gate voltage of a field effect transistor Q2 is increased, and the apparent synthesized capacitance of capacitors C6, C7 is enlarged to increase the base current of a transistor Q1, whose oscillating frequency is sunk, and the output of the inverter circuit 2 is increased.

Filed: 1987-12-18
Abstract: PURPOSE:To eliminate the use of a retrieving code and to improve the operability at a terminal side by storing a voice message from a transmitting side terminal and the drawing data of a caption and outputting the voice message in accordance with the caption selection of a receiving side terminal with an electronic exchange. CONSTITUTION:When a transmitting person dials a special code from a telewriting terminal 12, an electronic exchange 1 sends a prescribed guide message with a voice after the code is recognized. The transmitting person hand-writing-inputs the prescribed caption from an input part 12a and inputs the voice message from a voice transmitting- receiving part 12c. The exchange 1 stores the voice mail to a memory circuit 6. At such a time, since a discriminating circuit 3 discriminates that the caption (drawing data) is included, a control circuit 9 corresponds to the discriminating information and the address of the circuit 6 and stores them. On the other hand, when the receiving person dials a special code for displaying a caption from the terminal 12, only the caption part of respective mails through the exchange 1 is displayed at a displaying part 12b, and therefore, the desired caption is designated. Thus, the voice message of the corresponding mail is sent from the exchange 1 to a receiving side terminal 12.
