Title: Constant weight sorting apparatus for egg
Inventor: SASAKI SUSUMU
IPC: B65B23/06
Filed: 1987-04-30
Abstract: PURPOSE:To cope with an increase in a feed speed, by providing a specific discrimination means, which discriminates which position an egg must be sorted and recovered in feed order on the basis of a weighed value, with respect to each of successively fed eggs. CONSTITUTION:At first, it is judged whether the sorting of a constant number/constant wt. sorting station is proper on the basis of a weighed value G of each piece of egg. That is, not only an addition value A wherein the weighed value G, which is within the wt. range of Table II, is added to the total wt. GRAM of eggs already sorted and recovered in a container according to formulae i, ii but also a value B which is obtained by multiplying the average wt., wherein a set wt. CONST is divided by a set number NUM by a value N wherein I is added to the number of the already sorted and recovered eggs are calculated and, when the addition value is within set tolerant difference with respect to the multiplied value B, the eggs are sorted and recovered. Then, it is judged whether the sorting in a constant wt. sorting station is proper. That is, when the weighed value G is within the wt. range of Table III and the value wherein G is added to GRAM is below the value wherein the tolerant difference is added to the set wt., the eggs are sorted and recovered. In the sorting according to JAS, it is discriminated which grade of Table I (G) belongs to.

Title: Pellicle
IPC: G03F1/62
Filed: 1992-04-01
Abstract: PURPOSE:To obtain a silicone tacky adhesive layer which is not degraded in tackiness power in spite of irradiation with an excimer laser by using a silicone tacky adhesive as a tacky adhesive used for fixing a pellicle to a reticule. CONSTITUTION:This pellicle is constituted by extending a pellicle film to one end face of a pellicle frame and forming the silicone tacky adhesive layer on the other end face. This tacky adhesive layer is protected by a separator coated with a fluorine modified silicone mold release agent. This silicone tacky adhesive is not degraded in its tackiness powder even when the adhesive is irradiated with g rays and i rays or UV rays, such as excimer laser and, therefore, the pellicle fixed to the reticule by this silicone tacky adhesive is not dislodged from the reticule even when irradiated with the UV rays or excimer laser. The fluorine modified silicone mold release agent yields a cured film and, therefore, the migration of the mold released components to the tacky adhesive layer does not arise and an excellent releasing property is imparted to this silicone tacky adhesive.

Abstract: PURPOSE:To surely prevent generation of contact inferiority between a movable piece and a fixed piece by making the outside diameter dimension of one operation shaft of an operation piece smaller than the inside diameter dimension of a coil spring and also forming the width diameter of a slot larger than the outside dimension of an engaging shaft. CONSTITUTION:The outside dimension of one operation shaft 41a of an operation piece 36 is made smaller than the inside diameter dimension of a coil spring 43, and also the width diameter r of a slot 44a is made almost the same as the outside diameter dimension of an engaging shaft 45. Moreover, the outside diameter dimension of an operation shaft 41b is made almost 80-90% of the inside diameter dimension of the spring 43, and also the width diameter r of the slot 41b is made larger than the hole diameter r of the hole 41a of one operation shaft 41a almost by the amount of difference between the outside diameter dimension of one operation shaft 41b and the inside diameter dimension of the spring 43. Hereby, the width diameter r of a slot 44b is made larger than the outside diameter dimension of an engaging shaft 45. As a result, even if the reverse angle of a movable piece is small, the generation of contact inferiority can be prevented surely, and reliability can be elevated without increasing the number of parts.

IPC: G03G5/00
Filed: 1992-04-01
Abstract: PURPOSE:To obtain the method for regenerating an electrophotographic sensitive body which enables the repetitive use and regeneration, many times, of a conductive base body by peeling a charge transfer layer by the use of an org. solvent, then again forming a charge transfer layer, thereby regenerating the electrophotographic sensitive body. CONSTITUTION:The org. solvent 2 is housed into a peeling chamber 3 and the electrophotographic sensitive body 1 after plate wear is immersed into the org. solvent 2 housed in the peeling chamber 3. The electrophotographic sensitive body 1 immersed in such a manner is rotated by a rotating member 4 and the org. solvent 2 housed in the peeling chamber 3 is circulated in the peeling chamber via a pump 5 and a filter 6, by which the charge transfer layer formed on the electrophotographic sensitive body 1 is peeled. The regenerated charge transfer layer is formed after the charge transfer layer is peeled and, therefore, the shorter time for the regeneration of the electrophotographic sensitive body is necessitated and the cost of the regeneration is reduced. Further, there is no need for a surface treatment to polish the surface of the conductive base body and the conductive base body is repetitively usable many times.
