Title: Method and apparatus for automatic coating
Inventor: OOTA KOUJI
IPC: B05B12/12
Filed: 1980-08-29
Abstract: PURPOSE: To control coating operation with high accuracy, by moving a coating gun along a direction opposite to the carrying direction of a workpiece synchronizedly with the movement of the workpiece being carried with a conveyer, and making the operation of the coating gun ON-OFF synchronizedly with its movement.  
     CONSTITUTION: When a workpiece, e.g. a car body A, to be coated is carried just before the position shown in the solid line in Fig. by a conveyer C, a fluid pressure is introduced into a cylinder 11 by striking with a limit switch (not shown), a stopper 9 rotates along the direction shown in the arrow b and engages with the body A, and the second carriage 4 moves along the same direction by conveying along the direction a. A carriage 2, coupled to the lower end of a chain B, moves along the direction d opposed to that of the carriage 4. Consequently, a coating gun 1 on the carriage 2 scans from the front to the rear on the backside floor of the car body A, as the body A is carried along the direction shown in the broken line, and sprays the paint at proper time by the rotation of a dog disc 22.

Filed: 1990-05-10
Abstract: PURPOSE:To give an alarm and to prohibit the start of laser beam machining to improve safety by automatically and securely detecting whether a protecting tube of a laser beam is mounted on a normal mounting position from the change of switching state of a limit switch. CONSTITUTION:The limit switch 39 has a pressure type contact 41, and when the laser beam protecting tube 11 is mounted on a normal position the contact 41 is pressurized and the switching state of the limit switch 39 changes, for example, changes from a closed state to an opened state.

Title: Focal length variable liquid crystal lens
Inventor: HIBINO KOETSU
IPC: G02F1/1337
Filed: 1991-05-23
Abstract: PURPOSE:To provide the focal length variable liquid crystal lens which does not require polarizing plates and is simple in construction. CONSTITUTION:This liquid crystal lens is constituted of a liquid crystal cell having the lens shape formed by subjecting a 1st oriented film 3 to an orientation direction in a lateral direction (p direction) and subjecting a 2nd oriented film 6 to an orientation treatment in the direction (q direction) perpendicular to the plane of Fig. The polarization component of the incident light in the direction (a) parallel with the orientation treatment direction (p) of the 1st oriented film 3 is an extraordinary ray to the liquid crystal molecules oriented in parallel with the above-mentioned (p) and is an extraordinary ray to the liquid crystal molecules oriented in parallel with the above-mentioned (q). The liquid crystal molecules change the direction gradually in the direction perpendicular to the conductive film according to voltages when electric fields are impressed to the lens and, therefore, the apparent refractive indices of the liquid crystal 8 change continuously from the value to the extraordinary ray to the value to the ordinary ray for the extraordinary ray components of the incident light in the above-mentioned (a) direction and (b) direction. The effect of varying the focal length is thus received.

Abstract: PURPOSE:To prevent irradiation fog due to diffused light at the time of exposure and to form an image high in fidelity to an original by forming a photosensitive laminate composed of a plastic film support having a turbidity coefft. of <=2% and a photosensitive layer formed on the support. CONSTITUTION:The plastic film support having a turbidity coefft. of <=2% is made of polyethylene terephthalate, polypropylene, polycarbonate, ethylene-vinyl acetate copolymer, or the like. This turbidity coefft. (%) is defined as T2/T0X 100, where T0 is the total light transmittance and T0 = parallel light transmittance T1 + scattered light transmittance T2. This photosensitive laminate is composed of the support and the photosensitive layer or these two and a protective layer. Since said laminate is small in an image line width to be changed, the dimension of the original image is enhanced in fidelity, and it can be used for micropatterning of a printed circuit plate.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To suppress displacement due to thermal expansion of a lid main body at the time of a high temperature by erecting a rib along at least a maximum main stress direction obtained by a finite element method on the thermal deformation of a lid main body. SOLUTION: A plurality of ribs R1 to R4 are erected on the rear surface of a lid main body 19, rigidity of the lid main body 19 is increased and displacement due to thermal expansion is suppressed. In the lid main body 19, the direction of displacement due to thermal expansion is different at each location. The directivity of displacement due to thermal expansion is analyzed by a finite element method. Namely, the model of the lid main body 19 without rib is made and a system on the whole displacement due to thermal expansion is analyzed by a computer, raising a temperature. In the lid main body 19, a maximum stress direction α1 along roughly left and right directions is shown in front and rear areas and the maximum stress direction along an oblique direction is shown in left and right areas.  Because the ribs R1 and R3 match with the maximum main stress direction α1 , displacement due to thermal expansion of the lid main body 19 is effectively suppressed.

A floating gate 12, which is a floating type electrode, is further installed high above in this area. The concentration of dopants in the drain 3 is made thinner than that of the source 4, thereby forming a depletion layer whose maximum width is thicker between the floating type electrode in the second region and the second region. It is, therefore, possible to prevent electrons from being scratched from the floating electrode to the second region during write in.
