Title: Laser scanning device
Inventor: WATARAI SHINICHI
IPC: H04N1/23
Filed: 1988-08-26
Abstract: PURPOSE:To correct decrease of luminous efficiency following generation of heat of a joint of a semiconductor laser by a method wherein a sampling comparison control signal is corrected with an integral value obtained by integration of an image signal, and a driving current of the semiconductor laser is controlled. CONSTITUTION:An output of a monitor diode 4 is converted by voltage with an amplifier 5a, and is compared with a level (reference level) of a LD power control signal Pc with a comparator 5b. When it is a level of a lower output than the reference level Pc, a light output control part 7 is made to an emission level of a high output. When it is a level of a high output, the light output control part 7 is made to the emission level of a low output. Together therewith, when a start signal (BD signal) BD is on, an integrator 6 is discharged to 0V and integrates an output of a monitor diode 4 of the amplifier 5a. Since the light output control part 7 is composed of a summing amplifier, a form in which an integral signal IS of the integrator 6 is added to an output SC of a gate 5c is outputted as a light output control signal LCS to an LD driver 3, and a driving current is controlled.

Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To easily regenerate a filter for exhaust gas purification which is a porous silicon carbide sintered compact disposed in an exhaust passage of an internal combustion engine with an inexpensive device without requiring many sensors, etc., by measuring the deposited particulate amt. of the filter and providing the system with a heater for filter regeneration forward on a gas inflow side and an air supply source for use at the time of regeneration. SOLUTION: Since a back pressure is increased by an increase in the deposition amt. of the particulates, such as soot, the particulate deposition amt. may be recognized by the measuring of the back pressure. The back pressure between the engine 40 and a honeycomb filter 11 at the time of operating the engine 40 is measured by a back pressure sensor 14 and a warning lamp for the need of the regeneration of the filter 11 is lighted when the prescribed back pressure is attained. The porous silicon carbide sintered compact of the honeycomb filter 11 for purification of the regeneration system 10 is excellent in heat resistance and even if the soot is burned with the heater 17 by supplying the air at the time of the regeneration, melting, etc., do not occur and the timing for executing the regeneration may be widely set.  The execution of the regeneration at a suitable period is made possible only by monitoring the back pressure. As a result, the easy regeneration with the inexpensive device is made possible without requiring the many sensors, etc.

Abstract: PURPOSE:To obtain the memory element of low write-in critical voltge and a small occupation area by a method wherein, of a source and a drain, one wherein a write-in voltge will be applied is formed into a self-matching structure, and the other is formed into a semiself-matching structure. CONSTITUTION:A drain D-layer, whereon a write-in voltage Vw is applied, is formed into self-matching structure, and a source S-layer is formed into semiself- matching structure. When the capacitance between a control gate CC and a floating gate FG is set at C1, the capacitance between the FG and a substrate B at C2, and the capacitance between the FG and the D-layer at C3 in such a manner that the C1 and the C2 are made larger than the C3, the wright-in voltage can be lowered substantially as it is clearly understood from the write-in mechanism. According to this constitution, the C3 on the D-layer is very small as it is formed in self-matching structure, and this makes a great contribution in lowering the write-in voltage Vw. Also, as the S and the FG are formed in semiself-matching style and can be formed in a superposed form, the occupation area of the memory element can be made small in size.
