Title: Production of magnetic recording medium
Inventor: BAN YASUAKI
IPC: G11B5/85
Filed: 1992-06-23
Abstract: PURPOSE:To improve mass productivity by introducing oxygen into an initial incident region of Co vapor and forming a nonmagnetic CoO ground layer. CONSTITUTION:While a high-polymer substrate 1 is made to travel along a cylindrical can 4, the nonmagnetic CoO ground layer is formed in the region on the side nearer the inlet of a nozzle 10 for forming the nonmagnetic CoO ground layer and in succession, A Co-O magnetic layer is formed on the side nearer the outlet. The nozzle 10 is disposed in proximity to the can 4 as far as possible at this time and oxygen is blown out toward the inlet side of the substrate 1 like an oxygen introducing direction 11, by which the quantity of the oxygen to be introduced is minimized. A shield 6 may be provided between the nozzle 10 and an evaporating source 8 to prevent an oxygen blow-off port from being closed by deposits during vapor deposition. The position of the nozzle 9 for oxygen introduction for forming the Co-O may not be near the outlet shield 7 and may be parted from the can 4. As a result, the magnetic tape having decreased drop-outs is produced with good mass productivity by one stroke.

Title: Rice cooker
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To improve safety to a steam port member against abnormal heating in a rice cooker of having no inner cap. SOLUTION: When heating to a pan 5 becomes abnormal, a quantity of radiation heat to a cover under face plate 44 increases. However, since a steam port 47 is not arranged just above a heating coil 11, thermal damage to the steam port 47 can be restrained. Even if a bucket 49 melts, the bucket 49 does not fall just above the heating coil 11. Therefore, a fear of causing firing can be prevented. Installation of the bucket 49 is incomplete, and the bucket 49 falls when it is used, and even if rice cooking heating is started in a condition of having no pan 5, thermal deformation and melting of the bucket 49 can be prevented.

Title: Porous block having tuff as aggregate, and structure using the same
Inventor: NAKADE NOBORU
IPC: E02B3/14
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain a porous block useful for shore protection block, a block for protecting the face of slope, etc., by sticking a cement paste to an aggregate formed by grinding tuff and hardening the paste into a porous state having open voids. SOLUTION: The cement paste is stuck to the aggregate 2 formed by grinding tuff, is hardened into a porous state having open voids by a conventional method to prepare a porous block 1. Since the porous block 1 having a structure like this contains tuff, which is porous and acidic, the alkalinity of cement is neutralized and the porous block 1 shows weak alkalinity as the whole. Since the aggregate 2 itself has a porous form, the porous block 1 is excellent in water retention and water absorbing properties as the whole. Consequently the porous block 1 useful as a structure for fish bank and a structure for channel is obtained.
