Title: Cushion material for floor surface of steel stairs
Inventor: ADACHI HIROSHI
IPC: E04F11/02
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent a slip when a person ascends or descends stairs and an injury when he/she falls down by bonding a magnet sheet which has a predetermined thickness and in which ferrite magnetic powders are blended at a predetermined ratio on a rubber chip sheet having a predetermined thickness to form a cushion material. SOLUTION: A synthetic rubber or natural rubber blended object is crushed by vulcanization or a waste tire is crushed to obtain rubber chip. Next, the rubber chip is solidified by urethane or rubber binder to form a rubber chip sheet having a thickness of 7 to 15 mm. Then, 80 to 93% of ferrite magnetic powders are blended in an elastomer component such as chlorinated polyethylene for magnetization after processing it like a sheet to obtain a flexible magnet sheet having a thickness of 1.5 to 3 mm. A non-magnetized face of the magnet sheet whose one face is magnetized by many poles is bonded on a rear surface side of the rubber chip sheet to form a cushion material. Consequently, it is possible to simply attach the cushion material to steel stairs and prevent a slip when a person ascends or descends the stairs and an injury when he/she falls down.

Title: Ultrasonic probing device
Inventor: MATSUSHIMA HIROSHI
IPC: G01N29/04
Filed: 1992-08-04
Abstract: PURPOSE:To obtain an ultrasonic probing device facilitating detection of a defect inside a structure even if the structure is thin and the defect at the joint interface inside the structure is thin. CONSTITUTION:An ultrasonic reflection layer consisting of a gas layer 17 which is formed by a case 16 with a cavity and a material 9 is provided at the bottom surface part of a material 9 of a structure. Also, by providing the ultrasonic reflection layer, a reflection wave 14 at the interface between the material 9 and the gas layer 17 becomes a complete reflection, thus increasing the intensity of the reflection wave 14 and facilitating detection even if the structure is thin and the defect at the joint interface inside the structure is thin. Where there is a defect inside the structure, ultrasonic wave does not reach the material 9 and the gas layer 17 so that the state inside the structure can be determined by examining the presence or absence of a waveform 19 which is observed by an oscilloscope 3 of the reflection wave 14.

Title: Method and apparatus for manufacturing inclined composite
Inventor: TOYODA SEIJI
IPC: H05K1/03
Filed: 1994-08-08
Abstract: PURPOSE:To provide a method and apparatus for manufacturing an inclined composite with perfect inclined composition by improving the productivity. CONSTITUTION:Ceramic powder, metal powder, a dispersion medium, a dispersion agent, and a binder are prepared, and a slip S is produced by blending these substances. The slip is cast in a mold to be subjected to a bubbling process through a porous body P before standing. After a lapse of predetermined time, a molding of an inclined composite is obtained through water absorption via the porous body P. Then the molding is subjected to a degreasing and baking process. As a consequence, an inclined composite can be manufactured which consists of ceramics and metal having a continuous variation of 1:0 to 0:1 in its composition ratio. In this instance. the blended layer is not formed In the bottom of the mold, thus it can be manufactured easily. Additionally, the precipitation velocity of particles is faster than in the green sheet, then the manufacturing time can also be shortened. As a result, the productivity can be improved.

Title: Decorative plywood and manufacture thereof
Inventor: FUJIMOTO RYOJI
IPC: B27D5/00
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent cracks from generating on a sliced veneer due to the generation of creaks on the face of a plywood by a method wherein the thickness of a surface layer veneer locating at the surface of the plywood is made thinner by surface grinding. SOLUTION: As a veneer 5c corresponding to the face of a plywood 2, a veneer, which is made thinner by surface grinding, is employed. As the veneer 5c, a thin one having the thickness of about 0.4mm is employed. Since the veneer, which is made thinner by surface grinding, is employed as the veneer 5c corresponding to the face of the plywood 2, first of all, even of cracks generate on the veneer 5c, the stress developing as the cracks generate is small, because the veneer 5c is thin. Accordingly, no crack on the veneer 5c propagates to a sliced veneer 3, resulting in preventing the cracks on the sliced veneer from generating due to the generation of the cracks on the veneer 5c.
