Patent JP-H02109258-A (JP)
Title: Alkali zinc electrochemical cell having reduced-mercury anode
Inventor: DEYUUEIN EMU RAASEN
IPC: H01M4/62
Filed: 1989-07-14
Abstract: PURPOSE: To significantly reduce the necessary quantity of mercury without having any deteriorating effect on battery performance by adding a small quantity of a specified organic wetting agent to zinc/mercury amalgam. CONSTITUTION: An organosilicide is a film forming organic wetting agent, and the surface of a zinc/mercury amalgam leading to an increase in hydrogen overvoltage is clearly coated with this material. The film formed by the organosilicide reduces the generation of hydrogen from the zinc/mercury amalgam during the reaction with alkaline electrolyte, and also substantially reduces the quantity of mercury necessary to form the amalgam with zinc which effectively reduces the corrosion of zinc. Thus, the quantity of mercury used in an alkali zinc-manganese dioxide electrochemical battery can be reduced.

Title: Chromatography device
Inventor: KANAMORI SHUNICHI
IPC: B01D15/08
Filed: 1985-08-20
Abstract: PURPOSE:To pack a packing material uniformly by detecting the number of projecting stages of the plungers of a telescopic jack and supplying an operating medium to the telescopic jack at pressure and flow velocity set according to the number of plunger stages based on the detected value. CONSTITUTION:The switch valve 64 of a switch part D is manually operated, and a port 64a and a port 64b are communicated to a port 64c and a port 64d, respectively. Air supplied from a compression air source 28 is led to a hydraulic pressure generating part B through a switch valve 24, and a piston 44 is caused to do reciprocating actions at a low pressure. Thus the plunger 72 starts projection. Upon the completion of the projection, the plunger 74 starts its projection. At this time, a projecting part 80 is unlocked out of a projecting piece 78c to return a switch valve 78, and the channels of switch valves 24 and 90 are switched. Thus the compressed air from the air source 28 is supplied to a generating part B at a comparatively high pressure, and the piston 44 is operated at a comparatively high pressure. Thus the pressing speed and application pressure of a cap 12 can be kept constant even if the cross section of the plunger 74 is smaller than that of the plunger 72.

Title: Method and device for slab molding
Inventor: IDE KENICHI
IPC: B21B15/00
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To make a correction of slab width direction expansion possible even when a large thickness reduction press is used by performing a width reduction with a width reduction press after a slab thickness is reduced with a thickness reduction press and, then releasing the thickness reduction press. SOLUTION: When a slab 1 is reduced in its thickness greatly by a thickness reduction press 2, it swells wavingly in a width direction. Even if a width opening is set to make the width in a desired plate width B, the desired plate width B cannot be obtained due to a rebound being caused after the reduction. When an initial condition, which has an influence on the rebound, such as a material quality, temperature are inputted, a control device 6 computes a width opening based on the existing data and indicates it to a width reduction press 3. The width reduction press 3 performs the width reduction of the slab 1 based on this width opening. Width of the slab 1 measured by a width meter 5 after the width reduction is fed back to the control device 6 so as to compute a difference ΔB between the desired plate width B and the measured width value.  The width opening is corrected based on ΔB and the initial condition and, it is indicated to the width reduction press 3. The desired plate width B is obtained by repeating this operation.

Title: Semiconductor device
Inventor: ANDO MAKOTO
IPC: H01L23/50
Filed: 1985-08-21
Abstract: PURPOSE:To form a bent part readily by only bending a lead pin without yielding micro-cracks, by forming the bent part of the lead pin, which is extended from a semiconductor package, so that the bent part is thinner than the other part. CONSTITUTION:The bent part of a lead pin 12, which is extended from a semiconductor package 14, is made thinner than the other part of the lead pin 12. The thin bending part is bent. When the lead pin 12 is bent downward with a bending position M as a center, facing surfaces 16a and 16a of a cut-out part 16 are brought close together. The thickness (a) of the bent part 12a is thinner than the thickness A of the lead pin (a<A). Therefore a deforming range (l), when the lead pin 12 is bent, is narrower than a deforming range L when the cut-out part 16 is not provided (l<L). Therefore, the deforming range of the lead pin 12 does not reach the extended edge of the package 14, in which the lead pin 12 is sealed.

Title: Fuel injection nozzle
Inventor: KAYANO KAZUO
IPC: F02M51/06
Filed: 1989-07-14
Abstract: PURPOSE:To make always precise fuel injection control using a small piezo element by furnishing a degree-of-opening setting member to adjust the opening of a jet, and providing a degree-of-opening adjusting means to operate the setting member and adjust the relative position of the member with the jet. CONSTITUTION:The fuel from a fuel supply device 3 is pressurized by a high pressure pump 2 and introduced to a valve chest 37, and a needle valve 43 is moved up to inject the fuel into the combustion chamber from a jet. When fuel supply from the pump 2 is stopped, the valve 43 is moved down with the energization force of a coil spring 45 so as to block the jet, and thus the injection is stopped. That is, the vertical motion of the valve 43 depends upon the pressurized fuel supply timing from the pump 2. During fuel injection, on the other hand, a piezo element 26 (opening adjusting means) is driven under control by a controller 51 according to the operating condition, so that the element 26 changes the elongation/contraction condition at the time of fuel injection to vary the degree of jet opening appropriately through a throttle shaft 47 (opening setting member), and thereby the fuel injection rate is controlled. In this arrangement it is not required to equip a function to necessarily close the jet fully.
