Title: Laser beam machine
Inventor: OKUBO HIDEYUKI
IPC: B23K26/046
Filed: 1986-11-11
Abstract: PURPOSE:To enable a laser beam to focus on the work face of a work with high accuracy by making freely movably the condensing lens provided for condensing the plural laser lights having different wavelengths and automatically adjusting a focus distance. CONSTITUTION:When a necessary laser light is selected, a rotation order is placed on the stepping motor 33 of a focus setting mechanism 32 from a control device 11. If the selected laser light is a CO2 gas laser light 12, for instance, a condensing lens 30 is moved to the specified height from a work face 7 so that this CO2 gas laser light 12 may correctly be focused on the work face 7 of a work, and fixed as well. In case of a He-Ne gas laser light 13, the condensing lens 30 is moved to the specified height from the work face 7 and fixed as well similarly.

Title: Photosensitive material drying method
Inventor: KAWADA KEN
IPC: G03D15/02
Filed: 1989-10-17
Abstract: PURPOSE:To shorten the drying time and to reduce the power consumption by detecting the humidity of a drying part which dries a photosensitive material and controlling the supply ratio of the amount of outside air and the amount of circulating air. CONSTITUTION:The humidity of the drying part 10 is detected to control the supply ratio of the amount of outside air and the amount of circulating air. Namely, a humidity sensor 98 detects the humidity of the drying part 10 to increase the amount of outside air supplied to the photosensitive material 12 when the detected humidity is larger than a specific value or decrease the amount of outside air supplied to the photosensitive material 12 when the detected humidity is smaller than the specific value, thereby maintaining the air state in the drying part 10. Therefore, the vaporization of water from the photosensitive material 12 is accelerated. Further, the air humidity in the drying part 10 properly is adjusted by detecting the humidity of air regarding the vaporization of the water from the photosensitive material 12. Consequently, the drying time is shortened and the power consumption is reducible.

Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for treating plasma for preventing abnormal discharge at carrying of a body to be treated, without generating changes in the design or deterioration of throughput. SOLUTION: The etching treatment of a wafer W placed on a lower electrode 106 in a treatment chamber 102 of an etching device 100 is carried out.

IPC: H04J3/00
Filed: 1991-09-19
Abstract: PURPOSE:To implement bit phase synchronization and frame phase synchronization while invalid data or a data delay in the frame phase synchronization is suppressed with simple configuration. CONSTITUTION:A byte just before a pointer in a reception frame (offset address #29) is detected by a #29 address monitor section 4' and a reception pointer is loaded to a down-counter 8 when the byte is outputted from a bit synchronization buffer 1.

Furthermore, in the case of converting a transmission line phase fluctuation into a stuff, an active stuff byte is generated in the buffer and a position signal of a specific byte in which an absolute time location is fluctuated is used for a load timing to the down-counter 8 and the reception pointer is used for load data.

IPC: E03F9/00
Filed: 1993-10-04
Abstract: PURPOSE:To suppress impact noise at the time of reversing a rake by installing a disc on an upper step sprocket rotation shaft and reversing the back surface of a rake main body while making it, rolling contact with the outer periphery of the disc. CONSTITUTION:An outer diameter (r) of. a disc 5 becomes (r)=R-s which is a value deducting a dimension (s) between a chain 1c and a back surface 2h of a rake main body 2A from a radius R of a picth circle 1D on a sprocket 1A. At the time of (r) <R-s, the rake main body 2A is reversed in the arrow (f) direction at a reversal attitude position of a rake 22 from the state where a roller 2e of the back surface 2h of the rake 2, the front side of a pin 1e of the back surface 2h makes contact with the outer periphery of the disc 5 and impact noise is generated. At this time, in comparison with a travel distance of a roller 2d to hit the outer diameter of a boss, a travel distance of the back surface 2h to hit the outer periphery of the disc 5 can be made smaller to any degrees, and the smaller the distance, the smaller the impact noise can be. At the time of (r)=R-s, the impact noise becomes zero, and relation of the outer periphery of the disc 5 and the back surface 2h becomes relation of rolling contact.

Title: Method for controlling speed change of hydraulically operated multistage transmission
Inventor: KUSAKA KOHEI
IPC: F16H61/14
Filed: 1988-10-27
Abstract: PURPOSE:To reduce shock generated at the time of speed change by carrying out deceleration with the direct coupling clutch of a torque converter kept engaged at the time of carrying out coasting deceleration from a high speed stage. CONSTITUTION:At the time of carrying out coasting deceleration from a high speed stage, the deceleration is carried out with a direct coupling clutch 8 kept ON whereas, on other occasions, speed change is carried out with the direct coupling clutch 8 kept OFF. Thereby, since the deceleration is carried out with the direct coupling clutch 8 kept ON only at the time of coasting deceleration from a high-speed stage, no engaging shock of the direct coupling clutch 8 is generated. Also, since transmission torque is small while the load of the hydraulic clutch of a hydraulically operated transmission 4 is small at the time of carrying out coasting deceleration from a high-speed stage, the speed change shock can be mostly absorbed even at the time of using a small capacity hydraulic clutch.
