Title: Nozzle plate having improved fluid constitution of ink jet printer
Inventor: MURTHY ASHOK
IPC: B41J2/14
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve an ink filtration characteristic of catching fragments, etc., by effecting resorption to an ink flow channel, a projection chamber, a nozzle hole, etc., by a laser inside a polymer film through a protecting film, and defining a flow feature of a nozzle plate. SOLUTION: A polymeric film 100 coated with a protecting film is positioned on a platen. A laser 114 projects light into the polymeric film 100, thereby carrying out resorption or ablation to a flow feature and forming a plurality of nozzle plates in the film. A laser beam 116 is orientated so as to pass a mask 118, and consequently collided to the polymeric film 100. As a result, a plurality of parts of the polymeric material are removed in a required pattern from the film, and consequently the flow feature of the nozzle plate is formed. Some of the substance removed from the polymeric film 100 forms decomposed product or fragments and is piled again on the protecting film on the polymeric film 100.

Title: Weight sensing device for cooking apparatus
Inventor: SUZUKI TOSHIAKI
IPC: A47J27/00
Filed: 1989-05-18
Abstract: PURPOSE:To enhance the accuracy in sensing the weight by incorporating such an arrangement that the distance of the axis of a leaf spring to the spring mounting surface of a chassis is the same as its distance to the spring mounting surface of a table, locating the axis of the leaf spring on the same axis as the center of the load, and thereby allowing the table to sink horizontally by this load. CONSTITUTION:The chassis 1 of a weight sensing device is secured to the bottom of an inner vessel 10, and a rice boiling heater 11 is mounted in a heater hold-down hole 8 bored in a table 5. Therein the center of the heater 11 is put identical to the center of a leaf spring 3, the distance wherefrom to the leaf spring mounting surface 2 of the chassis 1 shall be the same as the distance (x) to the leaf spring mounting surface 6 of the table 5. Accordingly the weight of the rice to be boiled accommodated in an inner pan 12 produces deflection of an angle theta to the leaf spring mounting surface 2 of the chassis 1, while the leaf spring mounting surface 6 of the table 5 bends the tip of the leaf spring 3 for an angle theta' to provide theta=theta'. This signifies that the table 5 sinks horizontally by the load, that should enhance the accuracy in sensing the weight.

SOLUTION: The auger 10 for an ice making machine includes an auger body 11 having a helical blade 11a on the outer periphery of a cylindrical body 11a, axis parts 12, 13, and connecting part 14, and the axis parts 12, 13 have parts 12b, 13b to be supported on a bearing, respectively, at each axially central part of cylindrical bodies 12a, 13a. And the axially central portions of the parts 12b, 13b each are clad with powder by welding and the outer surfaces of the clad parts are ground so that the outer diameter of each clad part is larger than that of the other part of the axis part 12. Thus when the outer surface of the clad parts are ground, the other parts of the axis parts 12, 13 are not ground, and hence loading of a grindstone 21 can be avoided and grinding work efficiency can be improved.
