POS data are entered at step S1. The input POS data are arranged and those data for a day on which there was no stock at the store opening time and for a day on which the goods are out of stock at the store closure time are discarded to formulate data sets of the daily sale amounts for individual goods. At step S3, non-routine goods are discarded. At step S4, basic statistic values of the goods, such as mean value, standard deviation, maximum value, minimum value, skewness value, kurtosis value, Geary value etc. of the daily sale amounts of the goods are calculated. At step S5, the goods are classified into one of preset plural types, such as Poisson type, normal type, causal type and other type. Besides, an optimum amount for restocking order is found on the basis of the class types.
摘要:
An optical exposure method in photolithography applied for precise processing when semiconductor devices are produced. A pattern on a photomask is projected and exposed on a register on a base plate with an exposure device including a deformation illumination system, a photomask and a projection lens. The deformation illumination system is composed of a light source, a diaphragm and a condenser lens, and the diaphragm is provided with a linear through-hole. The optical exposure method uses a ray of linear light for illumination or two rays of linear light for illumination that are parallel with the pattern. The two rays of linear light are symmetrical with respect to an optical axis. These rays are parallel with the pattern in a position separate from the optical axis of the exposure device when the photomask pattern is a line and space pattern.

When a ring with an exposed dental X-ray film mounted thereon is thrown into a first tank filled with a processing solution, the ring is scooped into a space of a ring-holding portion of a rotating arm through a first opening. As the ring-holding portion is moving in the tank, the ring is pushed by a tilted bottom portion while being held within the space by a release preventing wall and a door so that the ring is also moving together with the ring-holding portion. When the ring-holding portion has fully moved out of the tank, the door is opened and the ring is released from the space into an adjacent tank through a second opening.

A film holder is described for use in a dental X-ray film developing machine. The film holder has a stem portion, an engagement portion formed at one end of the stem portion a film-mounting portion composed of two support portions formed at the other end of the stem portion and extending out in an opposing relationship from the stem portion. Plural film-mounting projections are provided at different levels in the direction of the thickness of the film holder in the proximity of each of free end portions and base portions of the respective support portions, whereby a film can be placed between the support portions while being held between the projections. Also described is a film mounting stage for mounting a film on the film holder. The stage has a wall for placing the film thereon and film pressers extending from individual peripheral edges of the wall in correspondence to the respective sides of the film, and defines a film-holder-receiving recess having substantially the same shape in plan as the film holder and a bottom wall located lower than the wall.

A mark-bearing support for a dental X-ray film pack is disclosed. The support has an X-ray pervious bite portion to be clenched between upper and lower teeth and a support portion for temporarily holding the dental X-ray film pack thereon. The support portion is provided with a mark formed of an X-ray impervious material such as a lead-containing ink.
摘要:
A toothed belt power transmission system having a belt tooth configuration and pulley groove configuration providing for clearances between the belt tooth root and pulley groove outer surface, and between the belt tooth tip surface and pulley groove inner surface. A power transmitting surface on a midportion of the tooth has facial engagement with a confronting sidewall surface at the midportion of the pulley groove side surface. Locations of the centers of the different arcuate surfaces of the pulley tooth and belt groove for providing the extended life, low noise operation of the drive are disclosed. A number of different constructions embodying the invention are disclosed.
