Title: Moisture sensitive element
Inventor: SAKAI YOSHIRO
IPC: G01N27/22
Filed: 1988-06-14
Abstract: PURPOSE:To lower the quantity of the moisture to be adsorbed and to obtain a stable moisture sensitive characteristic with decreased drift by forming a moisture sensitive film by using a polymer polymerized with a methacrylate monomer having no hydroxyl groups. CONSTITUTION:The moisture sensitive film 3 is formed by coating a soln. prepd. by tentatively polymerizing the methyl methacrylate monomer (MMA) refined by vacuum distillation in the presence of a catalyst to provide a suitable viscosity soln. on a lower electrode 2 formed on an insulating substrate 1 by a spin coating method, then subjecting the coating to a heat treatment to complete the polymn. reaction. Gold is then stuck by a vapor deposition method on the insulating substrate 1 laminated and deposited with said moisture sensitive film 3 to form an upper electrode 4. The lower electrode 2 on the substrate 1 is formed in the form of a thin film by a vapor deposition method of platinum. The moisture sensitive film 3 is formed of the MMA as a starting material which is polymerized to the simple substance polymer of polymethyl methacrylate (PMMA) and is formed in a noncrosslinked state; therefore, the quantity of the moisture to be adsorbed decreases and the hysteresis decreased.

IPC: B23D23/00
Filed: 1985-07-02
Abstract: PURPOSE:To enable the cutting of a columnar metal or a pipe to a smooth edge by applying a constitution wherein a movable cutter inserted with a columnar workpiece having the same inner hole as a fixed cutter coaxially arranged is moved eccentrically for circumferential cutting all at once. CONSTITUTION:When a drive cylinder 8 is turned by a driving gear 12 in a cutting process, the external surface thereof gives circular motion along the circumference of the inner large bore part of a base 1 about a central point o' as an axial center via an outer bearing 10. And the internal surface of said cylinder 8 has a central point at an eccentric point o and gives eccentric motion due to a different axial center, when the drive cylinder 8 is rotated along the circumference of the inner large bore part of the base 1 via the bearing 10. The central point o turns 360 deg. about the central point o' with the rotation of the drive cylinder 8 and returns to the original position. Therefore, the central point o of a movable cutter 5 is shifted to o', and the maximum portion a of the wall thickness of the drive cylinder 8 and the minimum portion b thereof are exchanged for each other in position after 180 deg. rotation. Concurrently therewith, the movable cutter 5 gives circular motion without rotation about a fixed cutter 4 and shearing takes place smoothly at one edge where said cutters are in contact with each other.

Filed: 1989-06-07
Abstract: PURPOSE:To protect a read/write head and an IC card from static electricity by providing a mechanism for destaticizing the static electricity electrified to the IC card on an IC card insertion path. CONSTITUTION:A destaticizing roller 4 is placed on an IC card insertion path 3 leading to the inside of the device from an insertion port 2, and an electric resistance between the surface of the destaticizing roller 4 and a housing of an IC card reader/writer 1 is set in advance to 10kOMEGA - several 100kOMEGA. When a card 5 is inserted, the destaticizing roller 4 comes into contact with the surface of the card 5, and when the destaticizing roller 4 comes into contact with a terminal part 6 on the card 5, static electricity accumulated in the card escapes gradually through the terminal part 6 and the destaticizing roller 4.
