Title: Storage system
Inventor: SAKAGUCHI KATSUHIKO
IPC: G06F3/0487
Filed: 1987-05-22
Abstract: PURPOSE:To synthesize various images by specifying a range in accordance with a graphic pattern for inputting displayed information, and storing the information in a memory area in accordance with the shape of the graphic pattern. CONSTITUTION:A display means 300 displays information stored in a 1st storage means 100. On the other hand, an input means 400 inputs a graphic pattern. A graphic recognizing means 500 recognizes the shape and area of a graphic determined from the graphic pattern coordinates inputted by the means 400. The display information of the area recognized by the means 500 is read out from the information stored in the mean 100, and stored in a memory area of a 2nd storage means determined in accordance with the recognized graphic. Consequently, display picture information indicated by a pointing device can be optionally stored, and various image synthesis can be attained.

Title: Color television camera
Inventor: SUGITA MAMORU
IPC: H04N9/68
Filed: 1979-09-28
Abstract: PURPOSE:To suppress deterioration of white balance and also to obtain an NTSC signal of fidelity by making (gamma) corrections of red, green and blue signals, by mixing a luminance signal and modulated color signal, and then by making level corrections. CONSTITUTION:Signals G, R and B from terminals 1-3 are corrected by gamma-correcting circuit 5 and then mixed by Y matrix 6 at a prescribed NTSC ratio to generate a luminance signal. A color signal, on the other hand, is obtained by encoding gamma- corrected signals R and B by color signal processing circuit 8. Those luminance signal and color signals are passed through level correcting circuits 4 and 4' and mixed  into an NTSC signal by synthesizing circuit 9. This signal level is detected by level  detecting circuit 11 and gains of correcting circuits 4 and 4' are controlled with its  output. Thus, levels of signals R, G and B are never varied independently, so deterioration of white balance is suppressed and the NTSC signal of fidelity can be obtained.

Title: Stereo viewer
Inventor: AREN JII RUISU
IPC: G02B27/02
Filed: 1987-05-22
Abstract: A stereoscopic viewer (10) comprises a housing (32) having an advancing plate (90) for supporting and advancing a disc-shaped carrying card (14) for stereo images which are viewed through a pair of eyepieces (16R, 16L) in the housing. A trigger (156) oscillates the plate to incrementally rotate the card and position sequential pairs of images in the viewing axis of the eyepieces. The trigger includes a depressible actuator vertically projecting through a top surface (80) of the viewer, as it is held for viewing. The trigger comprises a cylindrical actuator portion (158) projecting through the top surface of the housing, and a leg (162) depending from the actuator portion which engages the advancing plate (90) to oscillate it as the trigger is depressed. As the plate oscillates in a forward direction, a flat front face (146) of a pawl (144) on the plate engages a radial slot (26) on the disc to rotate it. The pawl is slightly inclined in the direction of advance of the card to help hold the card flat against the plate during incremental advancement. A rear element (36) of the viewer is completely translucent to allow a greater amount of light into the interior of the housing and permit viewing of the mechanical actuation of the viewer.

Title: Membrane switch
Inventor: SUZUKI TOSHIO
IPC: H01H13/785
Filed: 1988-05-21
Abstract: PURPOSE:To prevent to generate a trouble to contact the upper contact and the lower contact particularly in winter, for example, by sealing a pressure sensitive material in a contact chamber. CONSTITUTION:By pushing a switch operating member 8, its pressing force is inflicted to a pressure sensitive material 5 through a damp-proofing member 7 and the upper contact 6. The pressure sensitive member 5 has a character to present the conductibility in the pressing direction, from the upper contact 6 to the lower contact 3, only when the pressing force is inflicted, forming a circuit, the lower contact 3-the pressure sensitive member 5-the upper contact 6the pressure sensitive member 5-the lower contact 3, to turn on the contact. In this case, since there is no air sealed in a contact chamber in which the pressure sensitive member 5 is provided, no leakage of air from the contact chamber to the outside is generated providing no phenomenon such as a change of the contact interval depending on the volume variation of the contact chamber, even though the surrounding temperature is varied. Consequently, a trouble such as the contact of the upper contact and the lower contact owing to the bending of the PFT film can be eliminated.

Title: Projection printer
Inventor: ISOHATA JIYUNJI
IPC: H01L21/027
Filed: 1981-08-08
Abstract: PURPOSE:To enable a mask, a wafer, and an image-forming optical system, etc. to be exactly moved, even if guide rails are not made so exactly, in a projection printer for use in fabrication of semiconductor circuit elements, such as IC, LSI, VLSI, etc., by providing plural floating members as sliding members along the guide rails, and controlling the floating force of these floating members. CONSTITUTION:Air bearing pats 31 are arranged, 2 on the forward bottom of the sliding member 50 of an arm, and 2 on the backward bottom. A gap between the pats 31 and a guide 26 depends upon the air pressure supplied to the pats and the weight of a moving body, increase of the air pressure narrows the gap and decrease of it enlarges the gap. Therefore, the body can be moved straight without pitching and rolling, etc., by controlling the air pressures of the forward and backward pats separately in accordance with the movement, even if the guide is bent.
