Title: Embedded type screw nail
Inventor: HASEGAWA TAKEO
IPC: F16B35/04
Filed: 1994-08-23
Abstract: PURPOSE: To eliminate the appearance of a gap between members, which is peculiar to a screw nail, strengthen the member joining force of the screw nail, and hide the whole screw nail in the members to improve the fine view of a use object such as furniture in the embedded type screw nail which is screwed into overlapped inside and outside members to joiningly retain both the members. CONSTITUTION: In an embedded type screw nail which is screwed into overlapped inside and outside members to joiningly retain both the members, about the spiral screw of a stem part, the pitch of a screw part 3a contacting the inside member of a screw tip part is set large, and the pitch of a screw part 3b contacting the outside part member on a nail head 2 side is set small.

Title: Method and instrument for measuring fluid resistance of cloth
Inventor: DEGUCHI JIYUNKO
IPC: G01N33/36
Filed: 1993-08-30
Abstract: PURPOSE:To easily measure the fluid resistance of cloth by making a fixture fitted with a cloth sample to sink in and float on a fluid while the fixture is supported with a thread. CONSTITUTION:At the time of measurement, a fixture 2 fitted with a cloth sample 3 is first placed in an inclined flow passage 4. Then a fluid is made to flow in the passage 4 by opening a valve 9 and the fixture 2 is made to sink in and float on the fluid. Under such a condition, the fluid flows down the passage 4 by passing around the fixture 2 with the sample 3 and a thread 1 is pulled by the resistance when the fluid flows around the sample 3, namely, by the resistance between the sample 3 and fluid. The tension of the thread 1 generated when the thread 1 is pulled is measured with a measuring instrument 5. The measured value indicates the fluid resistance of the sample 3, namely, the resistance of the sample 3 against the fluid flowing around the sample 3. Thus the fluid resistance of the cloth sample 3, such as the cloth for swimming suites for swimming races, etc., can be accurately measured with a simple facility.

Title: Optical character reader
Inventor: KOBAYASHI YOSHIKAZU
IPC: G06K9/20
Filed: 1987-09-22
Abstract: PURPOSE:To accurately detect the head of a slip by binarizing the output of an image sensor by an output from a white peak holding circuit, comparing the output of the white peak holding circuit with a fixed slice level and detecting the head of the slip. CONSTITUTION:A binarizing means (e.g. an A/D converter 8) binarizes the output of the image sensor 5 by the output (reference) of the white peak holding circuit 7. Even if the quantity of a light source 3 or external light for radiating the surface of the slip 1 is changed, the output can be accurately binarized. A comparator 10 compares the output of the circuit 7 with the fixed slice level determined from the output level of the image sensor 5 at the time of scanning a carrier surface to detect the head of the slip 1, so that even when the carrier surface (backing face) is not completely black and the quantity of light is varied, the head of the slip can be correctly detected.

Title: Core for die casting
Inventor: FUJINO KIYOSHI
IPC: B22D17/22
Filed: 1986-10-07
Abstract: PURPOSE:To crush a core after high-pressure casting and solidifying of molten Al and to improve workability by forming the core of a metal hydroxide the surface of which consists of strong metal carbonate at the time of mounting the core into a metallic mold for die casting of Al. CONSTITUTION:The movable metallic mold having a projecting part 2a mounted with the core 4 is clamped into the recess 1a of a stationary metallic mold 1 for die casting Al to form a casting cavity 3 between the recess 1a and the core 4. The core 4 formed by using the hydroxide such as Ca(OH)2, putting the molding to an autoclave of a gaseous CO2 atmosphere, subjecting the same to a heating treatment, and forming a hard CaCO3 layer of a high decomposition temp. on the surface of the core 4 is used in this case. The molten Al 6 in a casting sleeve 5 is press-fed by a plunger 7 through a runner 8 and a gate 9 into the casting cavity 3. Since the surface of the core is the hard CaCO3 layer, the shape collapse thereof does not arise. CaCO3 decomposes to CaO and CO2 and the inside Ca(OH)2 decomposes to CaO and H2O as well after the solidification of the molten Al upon lapse of time. The core collapse of itself simultaneously with mold opening. The die cast product is thus easily taken out.
