Title: Fabrication of semiconductor device
Inventor: NAGAI AKIRA
IPC: H01L21/336
Filed: 1994-03-15
Abstract: PURPOSE:To attain a low threshold voltage by forming a field insulating film for isolation and a gate electrode on the surface of a semiconductor substrate and then implanting ions to reach the semiconductor substrate thereby forming heavily doped P and N wells. CONSTITUTION:After forming a field insulating film 200 for isolation and a gate electrode 300 on the surface of a semiconductor substrate 100, ions are implanted to reach the semiconductor substrate 100 through the insulating film 200 and the gate electrode 300 thus forming heavily doped P and N wells 110, 120 in the regions for forming N-channel MISFET and P-channel MISFET, respectively. The P and N wells 110, 120 can be formed while being self-aligned with the field insulating film 200 and the gate electrode 300 by setting the thickness thereof and the ion implantation energy appropriately. This method realizes a low threshold voltage.

Title: Electromagnetic brake device
Inventor: EGUCHI MEGUMI
IPC: H02K49/06
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic brake device, which can control braking force freely regardless of a traveling speed of a vehicle, and can realize a smooth braking. SOLUTION: In a peripheral section of a magnet rotor 3 which rotates together with a rotary shaft 2, magnetic poles are formed in such a manner that a magnetic pole of one polarity is formed for one specified angle, and then a magnetic pole of the opposite polarity is formed for another specified angle and so on. In a stator on the side of the magnet rotor 3, a plurality of magnetic pole sections 5A-5D are formed at an angle half the location angle of the magnetic poles of the magnet rotor 3. In other words, the magnetic pole sections 5B, 5D are located at a phase angle half the angle between the adjacent magnetic poles of the magnet rotor 3. And, a magnetic pole sensor 7 is located closely to one 5A of the magnetic pole sections.  When a magnetic pole is detected by the magnetic pole sensor 7, a controlling circuit 8 magnetizes the magnetic pole section 5A-5D so that it may be magnetized in opposite polarity to that of the magnetic pole on the magnet rotor which passes through the magnetic pole section 5A-5D.

Title: Image forming device
Inventor: IWASAKI YUKIKO
IPC: G03G21/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a photoreceptor, for example, sticking of residual toner and foreign matter, chemical changes caused by them in image formation in a cleaningless system. SOLUTION: In the image formation in the cleaningless system using an electrophotographic process, the surface of a photoreceptor 6 is ground at a necessary degree for foreign-matter removal. Thus, the foreign mater such as residual toner is removed from the surface of the photoreceptor 6, and image quality deterioration is prevented. In the case, because the surface of the photoreceptor 6 is not ground more than necessary for the foreign-matter removal, remarkable scrape of the film of a photoreceptive layer, which occurs as in the case of cleaning in a blade cleaning system, is prevented. Therefore, the life of the photoreceptor 6 becomes long compared to that of the image forming device of the blade cleaning system.

Title: Holographic display
Inventor: TAKEUCHI SHOICHI
IPC: B60K35/00
Filed: 1993-02-09
Abstract: PURPOSE:To reduce the uncomfortable diffraction light stimulance purity due to external light by arranging the half-value width of the diffractive spectrum so that the aberration of the first hologram which can diffract the while light from outside the car as white is corrected with the second hologram. CONSTITUTION:A beam of light from a light source 16 is diffracted by the second hologram 19 upon passing through a lens system 14 and a transmissive liquid crystal display element 15 and further diffracted by a combiner 12 due to the first hologram of a wind-shield glass 17 so that the display information is viewed as a virtual image in the position 18 from the observing position 11. The first hologram is formed by widening the half value width of the diffraction spectrum, having such a spaciousness as capable of diffracting the white light from outside of the car as white approximately, while the second hologram 19 is exposed to the light so that the aberration of the first hologram is corrected. Thus the driver is given a clear field of view free from complementary color to lead to enhancement of the safety, and good information can be given with the aberration of display image reduced.

Title: Transmission power control system
Inventor: YASUKAWA KOUJI
IPC: H04B7/15
Filed: 1986-03-04
Abstract: PURPOSE:To apply sufficient compensation to an attenuation due to rainfall attended with scintillation by separating once a signal of a beacon wave or its equivalent radio wave, synthesizing the waves taking respective frequency characteristics into account, and controlling the transmission power based on the synthesized signal. CONSTITUTION:The strength of a beacon wave received by an antenna 1 is outputted from a conventional receiver 2. The signal is separated into two components (rainfall attenuation component and scintillation component) by an HPF 4 and an LPF 3 whose cut-off frequency is nearly 1/60Hz. The gain of amplifiers 6, 7 is selected respectively as 'about 1.5-1.7 power of the frequency ratio of a beacon wave to a transmission wave' and 'about 0.3-0.6 power of the said frequency ratio'. The two signals are synthesized by an adder circuit 8 to obtain a control signal of a transmitter 9. In controlling an output of the transmitter by using the signal, the variance in the signal intensity caused by rainfall attenuation and scintillation is absorbed at the time of the radio wave reaches a satellite.
