Title: Ball screw driven hydraulic control valve
Inventor: MIZUNAGA YASUO
IPC: B29C45/82
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To dispense with the discrimination between a lubricating oil for sliding a ball screw and a working fluid for hydraulic operation, to reduce the number of parts, and to simplify the structure by arranging a ball screw slide part of a hydraulic control valve to be suitably used in a hydraulic circuit of an ejection device of an ejection molding machine in a hydraulic control part.

Title: Artificial tooth for front tooth part
Inventor: AI MINORU
IPC: A61K6/083
Filed: 1988-08-12
Abstract: PURPOSE:To shorten a preparation time by dispensing with work partially eliminating the base bottom surface of an artificial tooth and to prevent the damage of the outer shape of the artificial tooth by providing a cavity having a specific recessed shape and the width and length of a neck part to a region from a base bottom part to a lingual leading end part. CONSTITUTION:The max. cavity depth 3 of an artificial tooth for an front tooth part is set to 0.5-5.0mm considering the size of a retaining device or connector of every kind. When the max. cavity depth is below 0.5mm, space including the retaining device or connector of every kind is insufficient and the bottom surface of the artificial tooth must be further eliminated and a dental technical operation time becomes long or the outer shape of the artificial tooth is often damaged. When the max. cavity depth exceeds 0.5mm, a ligulal diameter becomes necessarily large and a feeling of physical disorder at the time of mounting in the oral cavity increases. Further, the value of {(cavity long diameter 2)/(total long diameter 5)}X100 is set to 10-100%. The mix. thickness 4 of a neck part is set to 0.1-5.0mm. By this method, strength or abrasion resistance is also enhanced.

Abstract: PROBLEM TO BE SOLVED: To make it possible to estimate a defective state in real-time and obtain accurate tuning information for inspecting conditions by calculating a percent defective from correlation data determined by comparing the inspection result data with the repair result data in the past and the latest inspection result data. SOLUTION: The Inspection Section 1 is provided in each mounting line for electronic parts, and the Repair Section 3 repairs defective parts based on the inspection results from the Inspection Section 1. And the inspection result data 2 obtained from the Inspection Section 1 and the repair result data 4 obtained from the Repair Section 3 are stored in the Data Base Section 5. Arithmetic Section 6 determines and tabulates the correlations between the inspection result data in the past and the repair result data in the past, and the Memory Section 7 stores the correlation data as the results of arithmetic operations. The Estimate Section 8 estimates the percent defective of the latest inspection result data 2 and the repair result data 4 from the correlation data, and the Output Section 9 outputs the results of the estimate.

Title: Production of ink jet recording head
Inventor: MATSUMOTO HIROZO
IPC: B41J2/055
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To relax the limit to the difference between the coefficients of linear expansion of a substrate and a vibration plate by bonding a cavity plate and a vibration plate at temp. in the vicinity of the softening point of low m.p. glass. SOLUTION: A substrate 1 and a vibration plate 8 are bonded by using a low m.p. glass layer 12 being a bonding layer. Since the heating temp. of both of them is set to a range lower than the softening point of low m.p. glass by 50 deg.C or lower to temp. higher than that by 50 deg.C or higher, it becomes 250-450 deg.C. Since the substrate 1 and the vibration plate 8 are bonded at the temp. in the vicinity of the softening point, the flowability of glass is low and, by setting pressure force to 0.05-5kg/cm<2> and a holding time to 10-60min, the deformation or flow of the low m.p. glass layer 2 into a passage is not generated. However, the slight uneveness of the surface of the cavity plate, that is, the substrate 1 and the vibration plate 8 can correspond to the plastic deformation of the glass layer.

Abstract: PROBLEM TO BE SOLVED: To prevent seizure of a distribution shaft fitted so as to slidably rotate to a hydraulic head of a distribution type fuel injection pump in an oil-sealed manner by providing a space for interrupting transmission of internal stress between the shaft and a female thread hole of delivery holder formed in the vicinity of the shaft, between the shaft and the hole. SOLUTION: In a distribution type fuel infection pump, three delivery holders are arranged around a distribution shaft 5 in the case of three cylinders while four delivery holders are arranged therearound in the case of four cylinders. High pressure fuel oil is fed to each holder and also high pressure fuel oil is fed to the shaft 5 and a barrel of the shaft 5. A vertical groove 22 is formed between a female thread hole 1a of a hydraulic head 1 into which a delivery holder is screwed and a distribution shaft hole 1b into which the shaft 5 is accommodated so as to rotate freely, and the groove 22 serves as a stress interrupting space. The groove 22 is formed in a circular arc shape coaxial with the shaft 5.  Accordingly, transmission of deformation stress to the shaft 5 when the pressure of fuel is turned into a high pressure is interrupted and seizure of the distribution shaft 5 is prebented.
