Title: Manufacture of field-effect transistor
Inventor: KATOU NAOKI
IPC: H01L29/812
Filed: 1981-03-03
Abstract: PURPOSE:To decrease floating capacity by selectively changing a negative resist on the surface of a gate electrode into negative by utilizing the high electron ray reflection factor of a gate electrode material and forming source and drain regions through ion implantation while using the resist as a mask. CONSTITUTION:An N layer 2 functioning as an active layer is shaped onto a GaAs semi-insulating substrate 1, and an insulating film 5 serving as a spacer is formed in the thickness of 0.5micron or thicker. The insulating film 5 is etched through the side etching of approximately 0.5 micron while using a resist as a protective film, and a heatproof schottky gate 4 is formed through the evaporation of Ti-W, etc. and a lift-off. The negative type electron ray resist 6 is applied, and electron rays are irradiated to a 6' section. Since the gate 4 reflects 50-60% of incident electrons, only a section on the surface of the gate 4 can be changed selectively into negative when properly selecting the quantity of exposure. An N<+> region 3 is shaped keeping a proper distance from the gate 4 when ions are implanted employing the resist 6' turned into negative as the mask.

Title: Character processor
Inventor: TOSHIMA EIICHIRO
IPC: G06F17/22
Filed: 1988-02-09
Abstract: PURPOSE:To omit memories for 2nd and subsequent candidates and to realize the continuous input of characters by providing a mechanism in a homophone buffer to produce following candidates through reconversion with no possession of all conversion candidates. CONSTITUTION:Key data inputted from a keyboard KB is held by a keyboard buffer KBBUF until converting conditions are ready at KANA (Japanese syllabary)/KANJI (Chinese character) conversion. When the converting conditions are ready, the KANA/KANJI conversion is applied to an input reading string of the KBBUF. Then the converted reading string is sent to a text buffer TBUF for display. In case the 1st candidate of a certain conversion result is not desired, the 2nd and subsequent candidates are displayed with an instruction and the KANA/KANJI conversion is carried out again based on the reading and reconversion information stored in a homophone buffer DBBDY. Then the conversion candidates are listed. Thus it is not required to list up all conversion candidates within the DBBDY and therefore the memories can be omitted for the 2nd and subsequent candidates. Then the limitation is reduced for the continuous input of character.

Inventor: LEVY ALAIN
IPC: B60L11/18
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce the overload of a transistor, when the rotor of a motor does not rotate, by making a chopper frequency lower than that of the pulse width modulation for the case in which the rotating speed of the rotor is different from zero, when the rotating speed of the rotor is zero. SOLUTION: Two transistors which are executed for a period of time longer than the executing period of other transistors, when the rotor of a motor is started or stopped are provided and the control and modulation of transistors 1z1 -16 are executed at a frequency which is substantially lower than the modulation frequency during normal operation, when the rotor is started or stopped, in order to prevent the transistors from becoming excessively large or the characteristics of the motor from lowering. If the modulation frequency during the normal operation is 8kHz, the modulation frequency at the starting time, for example, falls within the range of 1kHz.  In an preferable example, the modulation frequency f' is selected when the rotating speed of the rotor is low, and the losses of the transistors at the time of stopping or starting the rotor become equal to those during normal operation at a frequency (f).

Title: Switching power supply
Inventor: SEKINE YUTAKA
IPC: H02M1/14
Filed: 1995-01-26
Abstract: PURPOSE: To suppress a harmonic current over a wide range by a method wherein a capacitor is discharged when an input voltage is lower than a capacitor voltage and the capacitor is charged by an energy from a choke coil when the input voltage is higher than the capacitor voltage. CONSTITUTION: If an input voltage is gradually elevated, a differential voltage between the voltage of capacitors C1 and C2 and the input voltage is applied to a choke coil L1. If the ON-period of a switching device Q1 is constant, a current applied to the choke coil L1 is proportional to the input voltage only when the input voltage is higher than the voltage of the capacitor C1 and C2. This state is continued until the input voltage becomes lower than the voltage of the capacitors C1 and C2 in accordance with the elevation or decline of the input voltage. Therefore, the choke coil L1 functions as a step-up chopper and the input current can be proportional to the input voltage and hence the input current contains only a low harmonic current.

IPC: B60L3/00
Filed: 1995-02-20
Abstract: PURPOSE: To prevent noise due to an alarm sound by controlling the time of generating an alarm according to an acceleration and the lighting state of a headlight, and generating the sound at a suitable time. CONSTITUTION: A vehicle speed sensor (e), an acceleration sensor (f) and a headlight lighting switch (g) are connected to a controller (d) which decides and controls the on-or-off of an alarm unit based on the signals from the sensors or the switch. In this case, if an alarm sound is not necessarily generated, for example, at night or when starting and decelerating, the sound is not generated. On the other hand, only when the headlight is put out, the vehicle speed falls within a predetermined range and the absolute value of the acceleration is a predetermined value or less, the sound is generated to inform a pedestrian of the approach of a vehicle. Thus, the noise due to the sound can be prevented while enhancing the safety.
