Title: Method for processing silver halide color photographic sensitive material
Inventor: ISHIKAWA MASAO
IPC: G03C1/035
Filed: 1985-04-30
Abstract: PURPOSE:To considerably reduce a change in the development of a silver halide color photographic sensitive material by reduced replenishment when the sensitive material contg. a specified cyan coupler is color developed, by replenishing a replenisher for color development contg. bromide during color development. CONSTITUTION:When replenishment is reduced so as to reduce environmental pollution and cost, a change in the development of a color photographic sensitive material and the stain of the material by development increase. Especially when a silver halide color photographic sensitive material is color developed while a replenisher for color development is replenished by <=9ml per 100cm<2> sensitive material, the unfavorable phenomena increase remarkably. The silver halide color photographic sensitive material contains a cyan coupler represented by formula I, II or III and has an emulsion layer contg. core-shell type silver halide particles contg. >=3mol% silver iodide. The concn. of bromide is kept at a value which does not interfere with color development by regulating the amount of bromide in the replenisher for color development to <=3.0X10<-3>mol, so replenishment can be reduced to <=9ml/100cm<3>. The replenisher is preferably replenished by 3-8ml in consideration of evaporation.

Title: Laser beam machining method
Inventor: KURIYAMA KATSUHIRO
IPC: B23K26/064
Filed: 1990-04-10
Abstract: PURPOSE:To hot process a brittle material without cracking by relatively moving a condenser lens and a work on an optical axis and processing the work while changing the beam spot diameter of the work. CONSTITUTION:The condenser lens 1 is moved to the position apart by a distance A from the surface of the work 2. The distance A is shorter than a focal distance (f) and, therefore, if the surface of the work 2 is irradiated with a laser beam 3, the spot diameter D 1 of the laser beam 3 increases and the energy density decreases to prevent the cracking. The condenser lens 1 is then moved by  X in the direction increasingly distant from the work 2. The spot diameter D 2 decreases to minimum and the energy density maximizes to heat the surface of the work 2 when the condenser lens 1 comes to the position of the distance B with respect to the work 2, i.e., the position coinciding with the focal distance (f). The joint part of high strength is obtd. The thermal gradient of the work 2 is decreased when the condenser lens 1 is moved by - x until the distance from the work 2 attains A. In cracking is thus prevented and the good parts are obtd.

Title: Setting method for position of loose fit sleeve
Inventor: OGAWA SHIGERU
IPC: B21B37/42
Filed: 1979-07-30
Abstract: PURPOSE: To make the high speed rolling work possible, by slightly inclining the sleeve axis in order to displace the sleeve in the axial direction, by lowering the required strength of the sleeve position retainer, and by reducing the generation of the friction heat.  
     CONSTITUTION: When the sleeve 4 is to be displaced in the direction of arrow (y) along the roll axis, the support arm 5 is moved in the direction of arrow (y) in order to move the contactors 7, 7', in the same direction (y). The sleeve 4 receives a force in the direction of arrow (y) from the contactor 7; hereby, the axis of the sleeve 4 slightly inclines in the direction to turn the sleeve 4 in the speed direction W of the sleeve 4 at the loading point. Under this condition, the finite line A 0 B 0  has been transferred to the finite line AB. The finite line AB is transferred to the position of the finite line A'B' after being turned round in a very short time. Within this period of time, the support arm 5, that is the contactor 7, displaces in a distance A'B' and the inclination of the sleeve 4 is held parallelly to the chain line; hereby, the axial movement of the sleeve 4 is steadily carried out. Since the inclination of the sleeve 4 is small, the sleeve 4 can be moved by a very small force.
