IPC: G11B5/127
Filed: 1984-10-02
Abstract: PURPOSE:To reduce slide noise easily and surely by sticking a rigid adhesive to the lower end of the joint surface forming a gap of a head chip in a magnetic recording and reproducing device of the rotary head helical scan system.

Title: Graphic processing method
Inventor: MORINAGA HIDEHIKO
IPC: G09G5/24
Filed: 1990-08-03
Abstract: PURPOSE:To generate an appropriate graphic pattern by determining the attribute of a sampling point to be inserted based upon the attribute of its adjacent sampling points in accordance with an instruction for inserting the sampling point. CONSTITUTION:When M1 and M2 are specified as two adjacent points, the section E1M1M2E2 is changed to the section E1M1M3M2E2 as the result of a sampling point. A preferable example for the position of an insertion point is an intermediate point between the two adjacent points and the point attribute of the sampling point to be inserted is determined by the following rule. Namely, when two adjacent points are end points as shown in the section D2, the point attribute of the inserting point is determined as an end point because the specified section is a segment, and when either one or both of two adjacent points are intermediate points, the specified section becomes a curve and the point attribute of the inserting point is determined as an intermediate point. Thus, an appropriate graphic pattern can be generated.

Filed: 1985-09-19
Abstract: PURPOSE:To enable the production of a ZnSe semiconductor exhibiting P-type conductivity, by irradiating a substrate with partly ionized N, P or As in the molecular beam epitaxial process for the production of the ZnSe semiconductor having P-type conductivity. CONSTITUTION:A semiconductor single crystal or a GaAs single crystal is used as a substrate and ZnSe is metallized to the surface in vacuum. In the above process, beam of partly ionized N, P or As is radiated to the substrate at an ion energy of <=500eV and an acceptor impurity density corresponding to <=1/100 of the evaporated atomic density of the ZnSe beam incident on the surface of the substrate. The addition of the acceptor impurities to the substrate enables the production of a ZnSe semiconductor exhibiting P-type conductivity which has been difficult to be achieved. Accordingly, a P-N-junction light- emitting element useful as a light-emitting element of an LED and laser diode, etc., can be produced by this process.

Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To release the locking of a base part, being a cover, by a single finger and to perform oiling through one action without fouling a hand. SOLUTION: A cartridge type service tank is constituted such that a filling port cap 7 situated at a base part 8 rising and falling on a pival 25 is brought into close contact with a filling port 3 of a tank body 1 placed in an inverted state on an oil pan 4 and a lock means is provided to hold and release the close contact state. The lock means comprises a lock batch 31 attached on the tank body 1 side; and a hook fitment 32 mounted on the base part 8 and locked at the lock lot 31.
