Title: Picture recording and playback method
Inventor: OOHARA YUUJI
IPC: G03F1/00
Filed: 1979-12-03
Abstract: PURPOSE:To increase the fineness of details of picture and the sharpness of profile, by giving a specified relation between the number of scanning lines of picture input device using pickup medium such as two dimensional solidstate image sensors and that of a video recorder. CONSTITUTION:A memory 9 in which video information from a two dimensional solidstate image sensor 8 is recorded and stored, is set to an information playback device 11.

Title: Recording device
Inventor: SAWAKI TAKAFUMI
IPC: B41J25/308
Filed: 1989-06-21
Abstract: PURPOSE:To ensure that recording paper is printed with constantly appropriate stack volume regardless of the thickness of the paper by controlling the volume which adds to a line immediately preceding record data in a highlighted line based on the thickness of a recording medium. CONSTITUTION:A recoding head is capable of printing with an X line of data all at once and is compressed against paper for recording. The paper moves by a displacement amount obtained by formula X=2pirXtheta/360 with the rotation of a platen at theta  deg.. However, this formula represents only the displacement of the surface of the platen. Since it is the surface of the paper that is actually printed. X'=2pi(r+r')Xtheta/360 should be satisfied. In this formula, r' is the thick ness of the paper. The purpose can be achieved by adjusting the rotating angle thetaof the platen of a printer based on the stack volume N represented by formula N=2pir'Xtheta/360 after detection of the thickness of the paper.

Title: Organic positive temperature coefficient thermistor
Inventor: UCHIDA KATSUYUKI
IPC: H01C1/14
Filed: 1987-06-24
Abstract: PURPOSE:To obtain a high bonding strength and to reduce a resistance value change even after a long time use by forming a metal foil as an Ni foil having a specific surface roughness on its surface in contact with an organic positive temperature coefficient thermistor element. CONSTITUTION:In an organic positive temperature coefficient thermistor in which a metal foil is thermally press-bonded to the surface of an organic positive temperature coefficient thermistor element and used as an electrode, the foil is formed as an Ni foil having 1.0-2.0mum of surface roughness on its surface in contact with the element. When the surface roughness of the metal foil used as an electrode was varied to test the relationship of bonding strengths between the electrode, i.e., the thermistor and the metal foil, the degree of the roughness is not sufficient with the surface roughness Ra=1.0mum or less, and the bonding strength is low. If it is Ra=2.0mum or larger, particles of the roughened surface are exfoliated from the coil, and the bonding strength is extremely reduced. Particularly, as a result that electrodes are formed on a positive temperature coefficient thermistor element and executed for a conduction test, the electrodes of the Ni foil exhibited minus resistance value change to be stable.

Title: Shake correcting device and camera
Inventor: IMURA YOSHIO
IPC: G03B5/00
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent the unexpected movement of a VR lens holding frame, when shake is not corrected by fixing a frame in a direction nearly perpendicular to the optical axis, when the frame is at the rear end of a range where the frame can be moved in the optical axial direction. SOLUTION: When a base plate 6 is completely retreated to the rear of the optical axis, that is, a collapsing operation is completed, the hole part 7c of the VR lens holding frame 7 and a fixing rod 13 are fitted in their uniform section parts. In the uniform section parts in this case, their diameters are almost equal so that the hole part 7c can not be moved in the direction of a shake correcting surface. In other words, the VR lens holding frame 7 is fixed in the direction perpendicular to the optical axis A (the direction of the shake correcting surface). Thus, the holding frames 7 is retreated and the hole part 7c and the fixing rod 13 are fitted so that the holding frame 7 (an optical system 15) can be fixed in the direction of the shake correcting surface.
