Title: Method for applying photosensitive material to cylinder
Inventor: YAMAUCHI KYOJI
IPC: G03F7/20
Filed: 1988-09-30
Abstract: PURPOSE:To reduce operation and to improve the efficiency of applying the photosensitive material by moving a photosensitive material spraying nozzle at a prescribed moving speed and prescribed distance in accordance with the diameter value of a cylinder and the central position of the cylinder to apply the photosensotive material on the cylinder and drying the photosensitive material by a heater. CONSTITUTION:A control section 9 computes and calculates the diameter value of the cylinder and the central position of the cylinder 2 in accordance with the signal on the position where the cylinder and the sensor face each other and the signal on both end positions at the point of the time when the position detecting sensor 10 approaching the surface of the rotatably installed cylinder 2 in the direction perpendicular to the axial direction thereof arrives at the specified distance form the surface of the above-mentioned cylinder. Then, the control section controls the moving speed of the nozzle by moving the nozzle at the speed based on the diameter value of the cylinder so as to obtain the prescribed coating thickness. The photosensitive material spraying nozzle 4 is thus moved to the prescribed distance symmetrically laterally from the central position, by which the photosensitive material is applied to the prescribed region of the cylinder 2. The photosensitive material is dried by the heater 3 after the application of the photosensitive material. The efficiency of applying the photosensitive material is improved in this way.

IPC: A61B5/055
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a coil for MRI to be changed in size thereof for fitness even if size of a breast of a body to be examined is different. SOLUTION: This coil for MRI is provided with a coil conductor 11 formed into an enlarged diameter helical shape, of which diameter is enlarged from a first end 11a to a second end 11b of a space spiral shape and in which a distance between the first end 11a and the second end 11b can be freely extended or shrunken, and a capacitor C interposed in the coil conductor 11. The coil conductor 11 is made of a material having elasticity, and it is stretched in the condition that the external force is not applied, and it is shrunken by applying the external force. A necessity of providing plural kinds of coils for MRI having a different size is thereby eliminated, and the control is facilitated. Since the projection can be always performed in a size corresponding to the size of a breast, excellent SNR is obtained.

Title: Determining method for ice plug completion in piping freezing construction method
Inventor: SHIROMARU NOBUHIKO
IPC: F16L55/18
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To provide a positive, short-period determining method for ice plug completion. SOLUTION: Jackets 20, 22 are installed on piping parts 25, 26 for forming ice plugs, respectively. Refrigerants 23, 24 such as liquid nitrogen flow into the jackets 20, 22. The refrigerants 23, 24 held on the jackets 20, 22 cool a fluid in the piping starting from the wall side of the piping. Thus, the fluid is frozen starting form the inner wall side of the piping, growing the frozen fluid as far as the central part of the piping with the lapse of time. Freezing the fluid as far as the central part of the piping forms the frozen part into ice plugs 28, 30 for interrupting the flow of the fluid to block the fluid sandwiched by the ice plugs 28, 30. The pressure of the blocked fluid slightly increases due to the volume expansion of the frozen fluid.  Thus, after forming the ice plugs, the ice plugs exert the pressure difference of the fluid in the piping between a water cut-off region and a water cut-off-free region. Detecting the pressure difference determines the formation of the ice plugs.

Title: Earthquake control operation device for elevator
Inventor: OGUCHI TATSUHIRO
IPC: B66B5/00
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To improve an earthquake sensing accuracy by mounting a car vibration detector for detecting the vibration of an elevator car and activating predetermined control operation when an earthquake sensing device and the car vibration detector are simultaneously activated. SOLUTION: When an earthquake happens, a machine room 2 is vibrated at 130gal to activate an earthquake sensing device 10, thereby urging a relay 13. Since the machine room 2 is considerably vibrated but a car 3 is vibrated only at 10gal by this earthquake, a car vibration detector 11 is not activated. Since a contact 14a is open in this case, an earthquake control operation command device 15 is in an invalid state and an earthquake control operation is not activated. If the car 3 is vibrated at 100gal, the car vibration detector 11 is activated to urge a relay 14 and to close contacts 13a, 14a, whereby the earthquake control operation command device 15 produces output and immediately activates the earthquake control operation.  Since the earthquake control operation is performed when the vibration of the whole building including an elevator is larger than a predetermined value, the earthquake sensing accuracy is improved.

IPC: G03G5/147
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the erosion by a solvent from the end face of a photosensitive layer and to improve the reliability by coating a charge transfer layer so as to avoid the exposure of a charge generating layer. SOLUTION: An under coating layer(UCL) 2, the charge generating layer(CGL) 3 and the charge transfer layer(CTL) 4 are applied in this order on a cylindrical aluminum substrate. Namely, the ULC 2 and the CGL 3 are first applied on the aluminum substrate (1-a). Next, a solvent is applied on cloth and the CGC 3 is wiped at a size of A+2mm adding 2mm to the length A of the non- photosensitive layer and thereafter, the CTL 4 is applied thereon (1-b). Next, the layers are scored with lines by a cutter at a size of the length Amm and the CTL 4 and the UCL 2 are mechanically removed (1-c). In such a case, the strength of adhesion of the conductive substrate 1 is not high and, therefore, the mechanical removal is easy. The UCL 2 is a nylon resin, the CGL 3 is a phthalocyanine pigment and PVC-based binder and the CTL 4 is 6- dimethoxine-9, etc.
