Title: Production of stannous oxide having high purity
Inventor: TANNO FUMIO
IPC: C01G19/02
Filed: 1987-08-20
Abstract: PURPOSE:To easily produce SnO easily soluble in acid, having high purity, by adding chlorine compd. to an aq. acid soln. of stannous salt, the temp. of which is kept at a specified range and by treating at pH in a comparatively high specified range when SnO is produced from the aq. acid soln. of stannous salt. CONSTITUTION:The aq. acid soln. of stannous salt, as it is or diluted with water, is kept at 10-100 deg.C, and added with the chlorine compd. such as NH4Cl and further with an aq. alkali soln. while stirring to be regulated to pH9-11. The produced SnO is aged while keeping at the temp. and pH above-mentioned. Or, the SnO is separated and recovered, again dissolved in water, kept at 10-100 deg.C and added with the chlorine compd. while stirring, and then, the produced SnO is aged while keeping the temp. By this process, contamination of intermediate of SnO or hydroxide of tin can be possibly prevented and the SnO very easily soluble in acid, having high purity can be produced by the simple process.

Abstract: PURPOSE:To enable the primary mold clamping force to be changed arbitrarily in accordance with molding conditions by providing between a mold clamping ram and a movable disc a control mechanism which serves to vary the extending rate of a tie-bar during the mold clamping period in changing the operational stroke of the mold clamping ram by means of a screw. CONSTITUTION:A control mechanism 20 for the primary mold clamping force is provided between a mold clamping 16 and a movable disc 17 and the control mechanism 20 comprises cylindrical screw materials 21, 22 screwed in each other. In these screw materials 21, 22, the inside screw material 21 is fixed to the top end of the mold clamping ram 16 and the outside screw material 22 is secured rotatably onto the back surface of the movable disc 17 by means of a stop ring 23. And, in the outer periphery of the screw material 22, graduations 24 are given which show revolution number. In the injection-compressive molding machine of this type, the movable disc side can be moved in advance and retreat through rotation of the screw material 22, and since the operational stroke of the mold clamping ram 16 varies therethrough, the tie-bar 14 is given a proper extension even at the time when each of the mold thickness, molding article configuration, material resin, temperature or the like is changed, thus enabling fine control within a cavity according to the changing of molding conditions.

Title: Method for preventing of warpage in band-like material in the cross direction
Inventor: ASAHI ICHIRO
IPC: C23C2/20
Filed: 1988-08-18
Abstract: PURPOSE:To straighten the warpage of a sheet steel in the cross direction between wiping nozzles by detecting the warpage of the sheet steel to be galvanized in the cross direction with a detector installed near the wiping nozzles in a continuous hot dip zinc galvanizing apparatus and thereby driving a roll for straightening of warpage in a snout. CONSTITUTION:A sheet steel 1 discharged from a reduction annealing furnace 2 is passed into a galvanizing bath 4 of hot dip Zn, etc., to stick hot dip Zn to both faces of the sheet steel and a gas is blown thereto with wiping nozzles 7 outside of a galvanizing tank to make the sticking ratio of hot dip Zn uniform in the cross direction of the sheet steel. At this time, since the sheet steel 1 has warpage in the cross direction (so-called C warpage) and has different distance from the tip of the wiping nozzles 7, the coating weight of hot dip Zn is also made to inhomogeneous. The C warpage of the sheet steel is measured by a detector 9 for warpage installed near the wiping nozzles 7, thereby a straightening roll 8 in an apparatus 10 for preventing of C warpage is driven to give C warpage in the reverse direction to the sheet steel and the C warpage of the sheet steel is canceled to make a flat face without the C warpage between the wiping nozzles 7, by which the coating weight of hot dip Zn in the cross direction of both faces of the sheet steel 1 is made uniform.

IPC: B42D15/10
Filed: 1988-08-18
Abstract: PURPOSE:To make a memory card thinner and to add a rewrite preventing function to the card by connecting a solar battery to a rewrite preventing circuit, and integrally housing it into a plastic substrate together with a semiconductor memory circuit. CONSTITUTION:A RAM 1, a rewrite preventing circuit 2 and a solar battery 3 are integrally housed into a plastic substrate 4. The rewrite preventing circuit 2 consists of a serial body composed of a P-channel type transistor (TR) Q1 and an N-channel type TRQ2, and an N-channel type TRQ3, and the colar battery 3 is connected to the TRQ3. When light fallen on the solar battery 3 is shaded, the potential of a nodal point N1 held at a power source potential gradually decreases, an inverter circuit consists of the TRQ1 and TRQ2 is made non-conductive, and the potential of a nodal point N2 changes from a high level to a low level. Consequently, by connecting the nodal point N2 to a write/ read terminal R/W of the RAM 1, rewriting can be prevented. Thus, the width of the plastic substrate 4 can be suppressed to >= 1mm.

Title: Piston for internal combustion engine
Inventor: WASHISU TAKAHIRO
IPC: F02F3/00
Filed: 1985-09-17
Abstract: PURPOSE:To perform such lubrication that is conformable to lateral pressure as well as to aim at reduction in oil consumption, by setting each of gross equivalent sectional films of oil escape holes between the thrust side where the lateral pressure caused by explosive power of a piston works and the opposite thrust side where it will not work, to be different in size each. CONSTITUTION:An oil escape hole 4b at the thrust side 10a where large lateral pressure works at an explosion stroke of an internal-combustion engine is numbered six in total while another oil escape hole 4c at the opposite thrust side 10b is numbered four in total, respectively. These oil escape holes 4b and 4c are of the same diameter and any of them is interconnected with an oil ring groove 2c and an internal space 5 of a piston 10, respectively. Therefore, the gross equivalent section area totaling each equivalent section area is set to be larger at the thrust side than the opposite thrust side. Since an oil film to be formed in a cylinder inner wall at an upward stroke is set to be thicker at the thrust side than the opposite thrust side, a large quantity of lubricating oil can be scraped off as far as a portion for that, and no lubricating oil is left behind on the cylinder inner wall so that oil consumption is reduced.
