IPC: G02F1/133
Filed: 1995-06-30
Abstract: PURPOSE: To make possible the projection of an excellent color image by providing reflection surfaces on respective pixel electrodes according to respective pixels of R, G, B and deciding the slope angle of the reflection surface so that the reflection surface is orthogonally intersected with the incident direction. CONSTITUTION: When R light is made incident on the pixel electrode ER, the R light is reflected by the reflection surface of a reflection surface component 42R. The reflection surface of the component 42R is decided in the slope angle so that the incident R light is made incident on the reflection surface orthogonally intersectedly, that is, the main beam of light of the R light converged on the pixel electrode ER by a microlens RI is orthogonally intersected with the reflection surface. The slope angles of the reflection surfaces of the reflection surface components 42G, 42B in the pixel electrodes EG, EB are decided also so as to orthogonally intersect with the incident directions of the incident G, B light similarly.  Thus, since the light reflected by the reflection surfaces of respective pixel electrodes reverse move on incident optical paths, since the light incident on e.g. the pixel electrode ER is reflected, and is made incident on the microlens RI, no problem that (no microlens functions for a lens function) exists, and the excellent color image is projected.

Abstract: PURPOSE:To reliably fuse molten lead and the lugs of a plate group by slanting the bottom surface of a mold to form a space between the bottom surface of the mold and the end surfaces of the lugs and then pouring molten lead into the mold to form a strap. CONSTITUTION:The lugs 8 of a plate group 7 are inserted into the concave area 2 of a mold 1 which has a slant bottom surface 3. And, the projections 13 of the end surfaces 12 of the lugs 8 are brought into contact with the slant bottom surface 3 to form spaces 14 between the bottom surface 3 and the end surfaces 12 of the lugs 8. Next, molten lead 9 held in a manifold 5 is poured through an injection gate 4 to fuse the molten lead 9 and the lugs 8 of the plate group 7, thereby forming a strap 10. As a result, the lugs 8 are reliably fused to the strap 10 by bringing the molten lead 9 into contact with the entire surfaces of the lugs 8 except their projection 13 touching the bottom surface 3 of the mold 1. Furthermore, since the molten lead 9 is poured onto the higher area of the slant bottom surface 3 of the mold 1, the molten lead 9 favorably flows over the slant bottom surface 3 and the lugs 8 are equally molten, thereby improving the bonding between the lugs 8 and the molten lead 9.

IPC: H04N3/18
Filed: 1978-12-30
Abstract: PURPOSE:To prevent the break of the neck of a Braun tube to protect the Braun tube by providing a charging/discharging circuit and a high voltage breaking circuit which generate a short-circuit detection output for short-circuit of a vertical connection capacitor. CONSTITUTION:The voltage at negative-side terminal d of vertical connection capacity C1 charges capacity C4 with the time constant of capacity C4 and resistance R10 and discharges capacity C4 with the time constant of capacity C4 and resistance R11. The potential at point c of the positive-side end of capacity C4 is set to a value near zero and is prevented from being fluctuated, and emitter-grounded transistor Q5 of X-ray protection circuit P2 is held off. When capacity C1 is short-circuited, a DC is superposed to deflection yoke Y1, and the voltage at point d rises, and as the result, the potential at point c rises with the average value of point d, and Q5 is turned on to operate circuit P2, thereby protecting Braun tube BT1. By this constitution, in case that capacity C1 is interposed between Q1 and Q2 for vertical output and yoke Y1, tube BT1 is protected to prevent neck break. Even in case that no reference voltage giving circuit from the external exists in circuit P2, tube BT1 can be protected.

Abstract: PURPOSE:To reduce correcting time by controlling the operation speed based on a list designating the correlation between a head moving stroke and a scheduled speed in moving the head by a prescribed stroke so as to eliminate the stop of the head to an erroneous position. CONSTITUTION:When a stroke number Ns to move a head is given to a microprocessor (MP) 5 and the Ns is not 1, 1 is given to a mode command MS to bring the switch circuit to the state as shown in figure. When a unit stroke pulse TP reaches the MP 5, 0 is given to the Ns and a small value Va0 is given to the speed object value Va, an output is given to a DAC 8 from a setting means 40 to start the moving of the head 2. Then the speed object Va is selected to a schedule speed Vt of a speed table 6a and the result is outputted to the DAC 8. When the head 2 reaches nearly the constant speed, a speed detection means 31 calculates the actual speed V. The setting means 40 obtains a difference DELTAV between the speeds Vt and V and changes the Vt by a value multiplied with a coefficient thereto thereby deceleration more strongly the head 2 and stopping it at a correct position.

Filed: 1981-10-19
Abstract: PURPOSE:To reduce multipath noises by detecting AM components in intermediate frequency signals of two receiving circuits, comparing their detected levels with each other, and obtaining the output of one receiving circuit having a lower level. CONSTITUTION:Intermediate frequency signals from the intermediate frequency circuits 3 and 3' of two receiving circuits A and A' are AM-detected by AM detecting circuits 8 and 8' to extract only AM-modulated components.

Filed: 1991-07-05
Abstract: PURPOSE:To read recording information with only a 2nd higher harmonic and to decrease noises of the detection signal of a photodetector by providing a filter which cuts off primary light between a 1st separating means and a 1st photodetector. CONSTITUTION:The primary light after passing through a dichroic mirror 22 is made incident on the photodetection surface of a four-division photodetector 12 through, for example, a cylindrical lens 11.
