Title: Optical recording medium
Inventor: TOMINAGA JUNJI
IPC: G11B7/24065
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to read a micro recording mark speedily and also stably by sequentially laminating a 1st protective layer, an optical or thermal active layer, a 2nd protective layer, an optical recording layer, and a 3rd protective layer on a transparent substrate loading a compressed stress on the 2nd protective layer for enabling it to reproduce near field light, and controlling an aperture diameter of micro apertures generated in the active layer. SOLUTION: A size of micro apertures generated in an active layer is to be decided by a stress from a 2nd protective layer. When a stress acting on the 2nd protective layer is a compressive stress, the micro aperture is hard to open, and even when it opens, the diameter of the micro aperture becomes small when the compressive stress from the 2nd protective layer is large. It is preferable that the compressive stress acting on the 2nd protective layer is within a range of 200 Mpa-1 Gpa. This compressive stress can be adjusted by growing conditions at the time of forming the 2nd protective layer. Thus, it is possible to control the aperture diameter of the micro apertures generated in the active layer by adjusting the compressive stress acting on the 2nd protective layer.

Abstract: PURPOSE:To decrease a pseudo-gap output and to increase a yield by respectively specifying an angle to be made by the inner wall of a coiling channel and a gap facing part, an angle, which is made by the extended line of a gap and a magnetic film to be stuck to the inner wall, and the sticking direction of a magnetic material. CONSTITUTION:A channel 2 for coil winding is formed in one of substrates 1 and 1', which are composed of the magnetic material, at least. Then, a pair of core half bodies 4 and 4', for which a ferromagnetic metallic magnetic material 3 is formed in a gap facing part (a) of the substrate 1 and an inner wall part (b) to be continuous to the facing part (a), are joined and the gap is formed in the interval between the core half bodies. An angle theta1, which is made between the inner wall part (b) and gap facing part (a), is made to be <=40 deg.. An angle theta4, which is made between the extended line of the gap and a magnetic film 3 to be stuck and formed to the inner wall part (b), is caused to be >=10 deg.. An angle theta2, which is made by the sticking direction of the magnetic material and the perpendicular of the facing part (a), and an angle theta3, which is made between the sticking direction and a perpendicular to the inner wall part (b), are respectively caused to be about <=25 deg.. Then, difference theta2-theta3 is made to be about <=16 deg.. Thus, the pseudo-gap output can be decreased and the yield can be made satisfactory.

Title: Mode matching solid state laser using horizontal pumping
Inventor: TOOMASU MAIKERU BAERU
IPC: H01S5/022
Filed: 1990-02-23
Abstract: PURPOSE: To enable efficient mode matched pumping by specifying the folding angle of a zigzag-shaped resonator part. CONSTITUTION: The diameter of a fiber 28 is selected so that the area to be pumped can be matched with the size of mode of a laser. The diffusion of radiations from a laser diode in the other direction of a resonator plane is matched with the folding angle of a zigzag-shaped path for a TEMoo beam to pass through the block of solid laser materials 12.

Title: Electronic still camera
Inventor: NAGANO MASATOSHI
IPC: H04N5/225
Filed: 1990-02-26
Abstract: PURPOSE:To obtain an excellent video signal without disturbance from an image pickup element by stopping the focal length adjustment when the drive of an image pickup means is started during the focal length adjustment. CONSTITUTION:Large power is consumed immediately at the focal length adjustment of an image pickup optical system and a voltage of a power supply is tentatively dropped. The drop in the power supply voltage causes unstable operation in the image pickup means resulting in disturbing an output video signal. When the drive of the image pickup element 30 is started while the focal length of the image pickup optical system and the finder optical system is adjusted by a zoom button 40. the focus adjustment is stopped. Thus, the simultaneous execution of the focal length adjustment and the drive of the image pickup means is not implemented and the image pickup means is always operated stably. Thus, an excellent video signal without disturbance is obtained from the image pickup means 30.
