Inventor: SAGIYAMA MASARU
IPC: C25D5/10
Filed: 1990-11-30
Abstract: PURPOSE:To produce a ferrous alloy plated steel sheet excellent in press formability and electrodeposition coating property by subjecting a steel sheet to hot-dip galvanizing and to alloying and then exerting electroplating in an acid bath of ferrous alloy containing specific amounts of silica grains and nitric acid ions. CONSTITUTION:Hot-dip galvanizing is applied to the surface of a steel sheet and then heating is exerted to perform alloying, by which an alloyed hot-dip iron-zinc alloy coating layer as a lower layer is formed. It is preferable that, in this plating layer, Fe content and coating weight be regulated to 7-15wt.% and 30-120g/m<2>, respectively. Subsequently, electroplating is applied to this steel sheet by using an acid electroplated ferrous alloy coating bath containing 0.1-10g/l silica grains and 100-20000ppm nitric acid ions, by which an electroplated ferrous alloy coating layer as an upper layer in which 0.01-2% of silica grains are uniformly dispersed and coating weight is regulated to 1-10g/m<2> is formed on the above lower layer. By this method, the ferrous alloy plated steel sheet excellent in press formability and electrodeposition coating property and having plural plating layers can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent a temperature drop of a molten synthetic resin and to improve a molding accuracy by providing a heat insulating member made of a material having low thermal conductivity and a resin passage at a contact part of a mold having a resin passage with a movable nozzle having a resin passage. SOLUTION: A protrusion 7b of a heat insulating member 7 of a mold 1 is brought into contact with an end of a nozzle 8 of a heating state, a resin passage 8a is matched to a resin passage 7d, a molten synthetic resin is injected in a cavity 6 through the passages 8a, 7d. Then, the nozzle 8 is separated from the mold 1, brought into contact with next mold 1, and similar operations are repeated and molded. The member 7 brought into contact with the nozzle 8 is formed of a ceramic material having excellent wear resistance and low thermal conductivity. Hence, a wear is low therebetween to provide a long lifetime. When the nozzle 8 is brought into contact with the member 7, a heat of the nozzle 8 of the heated stat is less released because of heat insulation of the member 7.  Thus, a temperature drop of the molten synthetic resin can be prevented, a temperature change of the molten resin is reduced, and a molding accuracy can be enhanced.

Title: Nonvolatile semiconductor memory device
Inventor: UENPIN RUU
IPC: H01L29/792
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory device and its manufacturing method. SOLUTION: In a memory cell which is disclosed, a source 120, a drain 118a and a drain 118b which are placed asymmetrically on a semiconductor substrate together with a floating gate core on the semiconductor substrate are lined up. On the side of the source of the memory cell, a source diffusion is not spread so as to exceed an encroachment 116 by a thermal oxide, and it is separated from a floating gate core by a thick oxide in the encroachment. The thick oxide reduces the tunneling of electrons to a minimum on the side of the source. Since the source diffusion and a drain diffusion are arranged asymmetrically, the average dopant density of the source diffusion and that of the drain diffusion are larger than that in a memory cell which is doped asymmetrically in conventional cases.  A memory reduces the disturbance of a memory cell adjacent to a memory cell which is programmed, erased or read out. It can affect the programming operation, the erasure operation and the read operation of the memory cell.

IPC: B60L5/18
Filed: 1994-12-26
Abstract: PURPOSE: To measure the vibration and acceleration of a pantograph shoe even in a small room and eliminate the need of insulation measures by irradiating a reflector with laser light, detecting the Doppler effect of reflected laser light and determining the vibration and acceleration of the pantograph shoe through noncontact measurement. CONSTITUTION: When a Shinkansen(super-express railways) vehicle is running, laser light emitted from a laser sensor 14 advances straight in the horizontal direction and deflected to the vertical direction by means of an optical path conversion mirror 13 before being reflected on a reflector 12 buried in a shoe 11 on the lower surface side thereof. The reflected laser light is subjected to the vertical vibration of the shoe 11 to induce Doppler effect thus varying the frequency of laser light. The reflected light is deflected to the horizontal direction by the mirror 13 and received by the sensor 14. A signal is sent from the sensor 14 on an optical cable 16 to a measuring unit body 15, thence on a signal cable 17 to a data recorder 18 where the signal is recorded.  The recorded signal is processed to detect the vibrating direction and acceleration of the pantograph shoe 11 continuously, thus determining the position or extent of hard point or sagging of a trolley wire 8.
