Filed: 1982-06-28
Abstract: PURPOSE:To obtain an image having good luminance and contrast by forming a rear projection screen consisting of renticular lenses which have a prescribed width and are placed to face to each other, and emitting only the light projected from the renticular lenses on the incident side from the renticular lenses on the exit side. CONSTITUTION:Renticular lenses 8, 8' and 3 are provided respectively on the incident side and exit side of a rear projection screen 1. The projection light 4 by two different two-dimensional images is made incident to the lens 8 on the incident side and the other lens 8'. The width of each outlet side lens 3 is set at 2 times of the width of the incident lenses 8, 8', and the lenses are disposed to face to each other. The light 4 from the lens 8 is the exit light 6 directing from the lens 3 toward the left eye direction and the projection light 5 from the other lens 8' is the exit light 7 directing to the right eye direction. The full energy of the projection light which is made incident to the lenses 8, 8' is emitted from the lens 3.

Title: Production of silicon
Inventor: ITOU MUTSUHITO
IPC: C01B33/06
Filed: 1984-05-29
Abstract: PURPOSE:To produce highly pure Si, economically and efficiently, with a simplified means, by carrying out the complete reduction of a powdery mixture of SiO2 and a specific reducing agent instantaneously in a plasma gas stream. CONSTITUTION:1mol of powderly SiO2 (e.g. high purity quartz sand) crushed to about 200-325 mesh is added to a hot aqueous solution containing >=2mol of a reducing agent such as saccharose (in terms of C), kneaded homogeneously, dried, and pulverized to obtain powderly mixture of SiO2 and the reducing agent. The powder is thrown into the hopper 1, tansferred by H2 gas supplied to the feeder 2 attached to the bottom of the hopper 1, and introduced into the plasma torch 4 at the top of the reaction furnance 3. The powder is passed through the H2 gas plasma stream A of >=2,000 deg.C generated by the plasma torch 4, and is reduced completely and almost instantaneously to Si. The produced Si is cooled together with the gas stream with the cooler 5, separated from CO, H2 and stream by the separator 6, and delivered from the bottom of the separator 6.

Title: Paper feeding device
Inventor: SUZUKI YOSHIHARU
IPC: B65H3/52
Filed: 1985-05-21
Abstract: PURPOSE:To prevent forms positively from being fed while they are overlapped and being obliquely forwarded by dividing a reversely rotating roller into more than two pieces to the crosswise direction so as to allow them to touch a normally rotating roller and also to rotate independently in a paper feeding device equipped with a form separation section. CONSTITUTION:When a paper feed command is directed, a pick-up roller 4 is rotated allowing a form 3 to be taken out of a form stack 5 toward the direction A as shown by an arrow head. At this moment, a normally rotating roller 1 is driven by No.1 motor toward the form feeding direction, and two reversely rotating rollers 9L and 9R are driven by No.2 and No.3 motors reversely against the form feeding direction with a constant torque applied which is, for example, provided by a DC motor driven with constant-current applied. Besides, each of the reversely rotating rollers 9L and 9R is pressed against the normally rotating roller 1 with pressure. If the second form 3' is obliquely in mesh with between the normally rotating roller 1 and the reversely rotating roller 9L or 9R, the form 3' is immediately taken back by the reversely rotating roller 9L or 9R, whichever is in mesh with the form, and is corrected in such a way that the tip end line is brought in parallel with the axis of the reversely rotating roller followed by the conveying operation by conveying rollers 8 and 8'.

Title: Rotation detector
Inventor: NAKAURA SHUNSUKE
IPC: G01P3/49
Filed: 1989-04-28
Abstract: PURPOSE:To enhance the degree of freedom of the mounting position of an eddy current type displacement sensor and to lower mounting accuracy by arranging said sensor in opposed relation to the recessed or protruding part formed to the surface to be detected of a conductive material. CONSTITUTION:The output of the eddy current type displacement sensor 4 arranged in opposed relation to the recessed part 3 of a surface 2a to be detected changes in proportion to the distance from a conductive material. Therefore, when a rotary body 1 is rotated, the output S of an amplifier 5 changes. That is, when the sensor 4 is faced to a part other than the recessed part 3 of the surface 2a to be measured, since said distance is short, the output Sa is low and, since the distance becomes long at each time when the part of the recessed part 3 reaches in front of the sensor 4, the output Sa becomes high and a pulse is generated in a forward direction. A pulse detection circuit 6 detects the pulse from the output Sa of the amplifier 5 to output the pulse having the definite magnitude corresponding to the recessed part 3. Therefore, by detecting this pulse, the rotational state of the rotary body 1 is known.

Inventor: YAMATO AKIHIRO
IPC: F02D41/32
Filed: 1983-06-20
Abstract: PURPOSE:To ensure an engine for stable operating condition by selecting either a value of the pressure in an intake pipe sampled by an engine speed synchronous signal or an average of the values sampled at a quick frequency so as to determine a controlled variable. CONSTITUTION:The signal of the absolute pressure in an intake pipe 2 detected by a sensor 6 is sampled in a control circuit 12 by the TDC signal of a crank angle sensor 8 and stored in RAM 19. If the engine speed is low, the sampling is performed at a cycle of ten times per one turn of an engine and the sampled values are averaged and stored in RAM 19. If the engine is not idled, the map in ROM 18 is retrieved by the value compensated by the absolute pressure which is sampled by the TDC signal so as to determine the standard injection period. If the engine, on the other hand, is idled, the map in ROM 18 is retrieved by the average of the sampled values taken at a quick cycle. Even if the pressure in the intake pipe is pulsated, stable operating condition of the engine may be ensured constantly from the low to the high engine speed range.
