IPC: G03B27/32
Filed: 1987-05-29
Abstract: PURPOSE:To eliminate the labor for passing the front end of rolled paper into a recorder so that the paper can be easily loaded into the recorder by forming separable joint parts at two points near the terminal part of a rolled medium and setting the spacing between the two points at the spacing larger than the length at which the paper turns round an exposing part and developing part in the recorder. CONSTITUTION:A pair of the separable joint parts such as perforations 20, 21 are formed near a cassette 11 of microcapsule paper exposed from the cassette 11. The length existing between the perforations 20 and 21 is preset at such a length at which a user can easily cut the rolled paper 6 by turning the paper round an exposing plate 4 and press fixing rolls 5.

Title: Laminated magnetic core and manufacture thereof
Inventor: YUKI NORIO
IPC: H01F27/24
Filed: 1988-06-03
Abstract: PURPOSE:To prevent defective interlayer insulation by laminating magnetic core thin plates through a bonding agent based on sodium silicate which is mixed with an insulative powder. CONSTITUTION:Thin plates for use in a magnetic core are laminated through a bonding agent based on soda silicate which is mixed with an insulative powder. This insulative powder is composed of one or more than two kinds of alumina, magnesia, and silica powders. The thin plates for a magnetic core are laminated by utilizing the viscosity of starch syrup-like soda silicate. Mixture of a ceramic insulative powder such as alumina, magnesia, silica powder with the bonding agent based on soda silicate serves to prevent the laminated plates from being in contact with each other. The ceramic powder such as an alumina powder dose not come in contact with the thin plates for a magnetic core even during a high temperature magnetic annealing process. Further, since these powders are insulative, a very good interlayer insulation is ensured.

Filed: 1989-05-29
Abstract: PURPOSE:To provide the spring steel capable of securing high toughness in spite of its high hardness by reducing C content in a spring steel with a specific composition and adding specific amounts of Ni and Cr and also adding N by a specific quantity larger than conventional one, respectively. CONSTITUTION:This spring steel has a composition consisting of, by weight, 0.35-0.55% C, 1.80-3.00% Si, 0.50-1.50% Mn, 0.50-3.00% Ni, 0.10-1.50% Cr, 0.01-0.05% Al, 0.010-0.025% N, and the balance Fe and containing, if necessary, one or more kinds among 0.05-0.50% each of V, Nb, and Mo and/or <=0.0015% O. In the above composition, when C content is below the lower limit, sufficient strength cannot be obtained by hardening and tempering, and, when it exceeds the upper limit, toughness is deteriorated and a risk of quenching crack is brought about at the time of water quenching. Although Ni has a function of improving toughness, effect is insufficient when Ni content is below the lower limit, and, when it exceeds the upper limit, the effect is saturated and the possibility of forming retained austenitic is brought about. Cr has effects of improving hardenability and preventing decarburization due to Si, but the effects are insufficient when Cr content is below the lower limit, while a possibility of deteriorating settling resistance is brought about. N has a function of improving settling resistance and durability.

Title: Gas laser generator
Inventor: YOSHIZUMI SHIYUUZOU
IPC: H01S3/038
Filed: 1984-06-29
Abstract: PURPOSE:To continue stable glow discharge by coating at least the portion opposed to a laser gas passage of the surface of a cathode with an insulating layer of the thickness for enclosing the descending portion of the cathode in the thickness. CONSTITUTION:An anode 2 is common for discharge tubes 1, 2, and cathodes 3, 3 are disposed oppositely to the anode 2. An annular cathode 15 coated in contact with an insulating layer 14 by coating is held at the end of the tube. The layer 14, if excess thick, reduces electron emission capacity to need high voltage, and, if excess thin, increases a voltage drop. The layer 14 alleviates a local electric field concentration due to irregular surface of the cathode 15, and, in case of long use, it can prevent the surface of the cathode 15 from contaminating to prevent the local change of the electron emission capability from occurring. Thus, the glow discharge can be stabilized.
