Title: Transparent envelope for ohp sheet
Inventor: SUZUKI AKIO
IPC: G03B21/64
Filed: 1993-04-05
Abstract: PURPOSE:To prevent a part other than a printing area from being projected on a screen by providing an opaque mask means on the surface of a foldable transparent envelope part provided with an opaque flap. CONSTITUTION:Printing is performed on a non-picture area 7 on the transparent envelope part 2 constituted of such a transparent material as polyester, so that the area 7 is opaque. Any color can be used for the printing, if it is opaque; however, white color is desirable to make a note. The foldable opaque flaps 3a and 3b are spread to cover holes 4 for filing in the case of using an OHP, and also have a function to cover the part other than the OHP sheet on an OHP stage. Thus, the non-picture area (non-printing part) 7 is made opaque, and the envelope part is placed on the OHP stage while the flaps 3a and 3b are spread, so that an unnecessary bright part is not projected on the screen, the picture can be clearly seen, and presentation effect is increased.

Abstract: PURPOSE: To optimize a TV video signal and a personal computer video signal by discriminating whether an input signal to a video output circuit is the TV video signal or the personal computer video signal and switching the characteristic of the circuit according to respective images. CONSTITUTION: When a synchronizing signal is inputted to a discrimination means 13, the means 13 counts the synchronizing signal, and discriminates whether the signal is the TV video signal or the personal computer video signal from a difference of obtained frequencies. When the TV video signal is discriminated, a control means 12 switches a first switch means 10 to an (a) side, and makes a value of an emitter resistance deciding the serial negative feedback amount of the video output circuit a low value. Further, the control means 12 switches a second switch means 11 to the (a) side, and connects the power source of the video output circuit to the power source 9 of a high power source voltage. Thus, a dynamic range of an input/output characteristic is increased. Further, when the personal computer video signal is discriminated, reversed operation is performed.

Title: Method and apparatus for rolling of metallic plate
Inventor: KAWAI YOSHITO
IPC: B21B27/08
Filed: 1985-04-16
Abstract: PURPOSE:To cool a roll so as to have a uniform temp. distribution in an axial direction and to prevent the deformation of a roll sleeve by passing cooling water to plural cooling water passages parallel with the axial line to the inside of the roll near the surface thereof, sealing the cooling water into the cooling water passages and executing rolling. CONSTITUTION:A circulation pump 23 is operated to feed the cooling water in to the cooling water passages 20 in the roll, thereby cooling the roll body. Shutoff valves 25 and 28 of water feed and drain pipes 22 and 27 are then closed to confine the cooling water into the passages 20 and thereafter the rolling is executed. The valves 25 and 28 are opened to feed the cooling water into the cooling water passages 20 in the roll and to circulate the water upon completion of the rolling or upon ending of one pass. The roll is thereby cooled. The cooling water is sealed into the passages 20 on the inside of roll sleeve 7 in the stage of rolling, then the cooling water which is incompressible fluid transmits and supports the load during rolling to the core part of the roll inside, thereby preventing the deformation of the roll sleeve. The thickness of the roll sleeve is thus decreased and the cooling effect of the inside of the roll is improved without making inferior the shape of the metallic plate.

Title: Surface emitting type bistable semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/18
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a surface emitting type bistable semiconductor laser whose current region of a bistable operation is wide, which is operated stably, whose reproducibility is excellent and which injects a beam of light from a direction perpendicular to a substrate face and emits the beam of light in the direction perpendicular to the substrate face by a method wherein a ratio of a differential gain factor in the whole length of an excitation region to a differential gain factor in the whole length of a non-excitation region and a ratio of carrier natural lives are set so as to have specific relationships. CONSTITUTION:In this laser, a stripe-shaped active region 22 and an absorption region (non- excitation region 18) range in the longitudinal direction of a resonator. This is equivalent to a structure that an oversaturation absorber has been introduced into the resonator. A relationship between a phenomenon occurring in this case and various parameters has a relationship of g1/g2-tau1/tau2<-beta/1-beta with reference to a magnitude beta=halpha/GAMMA (where alpha: magnitude of absorption; GAMMA: lose of resonator) of the standardized nonsaturated absorption when a ratio of a length of an excitation region including an active region to that of the absorption region is (1-h):h, a ratio of a differential gain factor of the excitation region to that of the absorption region is g1/g2 and a ratio of carrier natural lives in the individual regions is tau1/tau2; a bistable operation is executed. In addition, reflection faces 25, 26 are tilted at 45 deg. with reference to the longitudinal direction of the resonator. A superlattice reflection film 11 is formed on the surface of a substrate. Accordingly, since a beam of light is radiated only on the surface of a second clad layer 14, an oscillation threshold value is not increased.

Abstract: PROBLEM TO BE SOLVED: To eliminate a pre-pit, to shorten a pitch and to enhance recording density by mutually recording/reproducing on both of a groove and a land. SOLUTION: An optical disk medium 12 is provided with the groove 2 recording address information by wobbling and the land 3 placing between the grooves 2 and without being wobbled, and makes possible recording/reproducing information on both. A head control circuit executes recording/reproducing by an optical head on the groove 2 and the land 3 alternately, and uses the address information of the just before groove 2 for the address information of the land 3. Then, a temporary address storage memory is provided for the address information of the land 3. In such a manner, since the information is made possible being recorded/reproduced on both of the groove 2 and the land 3, the pre-pit is eliminated, and the pitch is shortened, and the recording density is enhanced.  Further, high density information is recorded by controlling a rotational speed with a CLV system making the linear velocity of the disk medium 12 constant.

IPC: G11B19/04
Filed: 1985-04-15
Abstract: PURPOSE:To prevent the generation of a mechanical and an electrical destruction in a floppy disk device by conducting a power source only when the floppy disk is inserted into or mounted on an FDD. CONSTITUTION:By inserting the floppy disk 1, the end edge of the disk 1 abuts against the end surface 7a of a slider 7. When the disk is further inserted, the slider 7 moves together with the disk 1. When the disk is inserted into an inner part, the end surface 7a of the slider 7 abuts against a switch 8 and turns on the switch 8. Since this switch is connected to the power source switch of a system in parallel, the power source is turned on even when the power source switch is turned off and a spindle hub 6 starts to rotate. When the insertion of the floppy disk 1 is completed, a door lever 2 is inclined to a horizontal position, thereby, a plate 4 rotates and a collet 5 is fitted into the spindle hub 6 through the center hole of the disk 1.
