Title: Strengthening of plate-shaped metal material
Inventor: MATSUMOTO ISAO
IPC: B24C1/10
Filed: 1988-06-10
Abstract: PURPOSE:To strengthen a plate-shaped metal material free from deformation by projecting shot particles onto a number of dispersed places arranged along the directions X and Y and applying each compression stress at the dispersed places and setting the residual stress in an intermediate region between the contiguous dispersed places along the arrangement direction, different from the compression stress at the dispersed places. CONSTITUTION:Each dispersed place A is applied with a compression stress by projecting shot members onto the dispersed places A arranged along the directions X and Y in correspondence with the circular opened holes 3 in the shielding members 2a and 2b positioned on both the sides of a plate-shaped metal material 1. Further, the residual stress in the X direction in an intermediate region between the contiguous dispersed places A along the arrangement direction is set as the compression stress larger than the compression stress in the X direction at the dispersed place A, and the residual stress in the Y direction in the intermediate region is set as the compression stress smaller than the compression stress in the Y direction at the dispersed place A. Therefore, the plate-shaped metal member 1 can be strengthened free from deformation.

Title: Cargo transferring for traveling body
Inventor: KITA HIROAKI
IPC: B65G43/02
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To always maintain balance of a traveling body satisfactorily by transferring a cargo in the center of the traveling body all the time regardless of dimension and weight of the cargo. SOLUTION: If a cargo is detected by a photoswitch 5 or 6, a transferring conveyor device is driven in a carrying-in direction by driving a motor 3A, and time (t) required from detecting the cargo to stopping detecting the cargo by the photoswitch is measured. The length S of the cargo is calculated by the time (t) and the cargo conveying speed (v) of the transferring conveyor device 3. The stopping time T of the transferring conveyor device 3 is calculated by the formula 'T=(S1 -S)/(2v)' with the length S1 of the transferring conveyor device 3 in the load carrying-in direction, length of the cargo S, and the cargo conveying speed (v). When the stopping time T has passed since the cargo stopped being detected by the photoswitch, the motor 3A is stopped and the transferring conveyor device 3 is stopped.

IPC: F28F9/22
Filed: 1977-11-30
Abstract: PURPOSE: To improve durability and reliability, by perfectly removing stress to a sleeve by connecting a cover plate of a desuperheating portion in a deviation-possible shape in the axis direction of a body to the sleeve.  
     CONSTITUTION: When superheated steam with high temp is fed into a desuperheating portion 8 through a sleeve 14, and displacement due to the difference of thermal expansion is generated between a cover plate 8a and a body 1 or a tube plate 5 is deflected, the cover plate 8a slides between a seal plate 16 and a seal plate mounting portion 17, and moves in the axis direction of the body 1. Consewuently, when a hole 19 and the inner diameter of an opening 15 mounted to the cover plate 8a are set in appropriate dimensions the cover plate 8a directly contacts with the sleeve 14 even if the cover plate 8a displaces to the body 1, thus preventing the damages of the sleeve mounting portion without pushing the sleeve 14 in the lateral derection.

IPC: H01L21/3065
Filed: 1988-06-13
Abstract: PURPOSE:To increase a removal rate by correspondingly increasing the gas in a processing chamber under processing if a certain processing chamber is at a halt at the time of housing semiconductor substrates provided with resist films on the respective surfaces into the plural processing chambers and irradiating the substrates with UV rays to remove the resist films while passing gaseous ozone. CONSTITUTION:The gaseous ozone from a gaseous ozone generator 3 is diverted to the plural processing chambers 1 and 2 and the surfaces of the semiconductor wafers housed therein are irradiated with the UV rays to remove the resist films deposited on the wafers. The processing timing is shifted in the processing chambers 1 and 2 at this time; for example, the gaseous ozone passed to the chamber 1 thus far is added into the chamber 2 to speed up the processing if the processing in the chamber 1 ends earlier. The effective utilization of the gas in the parallel resist removing process is enabled in this way.

Abstract: PURPOSE: To keep a rotation of a drum at a constant speed and perform a secure sheet clamping by providing a load cam, cam follower or the like for regulating a change in a rotation load of the drum.  
     CONSTITUTION: By excitation of a solenoid 11, a cam ratch lever 5, a shaft 12 and an oscillating lever 23 make a united rotary motion, in which the oscillating lever 23 presses a cam follower 21 of a follower lever 22 against a cam edge 20c, and a drum 1 makes a united rotation with a load cam 20 so as to follow an arrow. When a cam follower 8 runs on a cam edge 4c, the cam follower 21 falls in an inclined cam edge 20b, and when the cam follower 8 falls in an inclined cam edge 4d as a result of further rotation of the drum 1, the cam follower 21 runs on a cam edge 20c. A load is instantaneously given to the drum 1 because of the running on action of the cam follower 21. This imposes a check on a abrupt decrease in rotation load of the drum 1 at a closure of a click 2 as well as prevents said drum from rotating too forward.

The electromagnetic waves in use should have a wavelength in vacuum ranging 10<-17> thru 10<5> m, favorably being ultraviolet rays or visible beams of light. The irradiation of the hole conveying layer can be performed by the use of a filter whose transmittance differs locally or by the masking method for partial irradiation. This allows provision of elements having different emitted light brightnesses on one substrate.
