Inventor: KODAMA MINORU
IPC: C23C2/40
Filed: 1980-07-26
Abstract: PURPOSE: To prevent the formation of a pickup on the surface of hearth rolls in a hearth roll type heat treatment furnace, by blowing a high temperature inert gas against the surface of a steel belt to remove bodies adhering to it when continuously heat-treating the steel belt in the heat treatment furnace of hearth roll type.  
     CONSTITUTION: When the steel plate 1 is heated at 300W600°C in the hearth roll type heat treatment furnace, hydrogen gas-containing nitrogen gas having a pressure of 5W10kg/cm 2  and heated to 300W600°C similar to the temperature of the steel plate 1 is blown against the surface of the steel belt 1 as a wiping gas from the slit 5 of a plurality of headers 4 installed in the furnace. The removal of rolling oils, iron powder, etc. adhering to the surface of the steel plate 1 eliminates the formation of a pickup on the surface of hearth rolls 3 and the formation of on the surface of the steel belt. As the wiping gas used in this process, an atmospheric gas in the furnace is drawn in from an intake vent 6 by a fan 9 and is filtered with a filter 8 to remove solid matter contained therein before it is circulated to the header 4 for reuse.

Title: Brain waves inductive device
Inventor: HASHIMOTO TAKESHI
IPC: A61M21/02
Filed: 1993-03-25
Abstract: PURPOSE:To provide the brain waves inductive device capable of adjusting the output voltage without stage and effectively using the power of the battery without excessive energy loss by producing the high pressure by a DC-DC converter and charging it gradually on a charge/discharge capacitor, and stopping the oscillation when it reaches the prescribed voltage. CONSTITUTION:The output voltage of a DC-DC converter 1 is divided by resistances 9 and 11 and potentiometer 10 which adjusts the output to the set voltage. When the voltage divided by the potentiometer 10 exceeds the Zener voltage of a Zener diode 12, the diode 12 is conducted to turn on transistors(Tr) 13 and 14. As the result, the voltage inducted to a feedback wiring 5 is short circuited to stop the oscillation of a Tr 6. Thus, the charge to a capacitor 8 is stopped to maintain the charge voltage to the set voltage. When the oscillation is stopped, the current from a battery 30 is made extremely small.

Title: Holding method for display of electronic weight measuring instrument
Inventor: ITANI MORIKAZU
IPC: G01G23/37
Filed: 1978-08-24
Abstract: PURPOSE: To improve operation efficiency by automatically resetting a holding state by resetting the hold display of a dislay part at timing for a change of one set value of tare or a unit price.  
     CONSTITUTION: With hold switch 8 operated, flip-flop 10 is set and the display of weight measurement part 2 at that time is held and displayed by display part 3. Before a time-up signal is outputted from timer circuit 9, the contents of unit-price register 4 are cleared by switch 7, so that the held display will immediately be cleared. When switch 7 is not operated within fixed time, the hold of the display is automatically reset by the time-up signal. Consequently, the hold is reset at the timing for setting change of at least either tare or unit-price set value so as to automatize the resetting of the hold, so that the operation efficiency can be improved.

Title: Alkaline zing storage battery
Inventor: FUJIWARA YOSHIKI
IPC: H01M4/38
Filed: 1986-05-06
Abstract: PURPOSE:To improve the cycle life of a battery as well as to control the size magnification of zinc active substance particles and to prevent the capacity deterioration of a zinc electrode, by applying zinc particles, on whose surfaces zinc oxide layers of 10 to 50wt% are formed, as a negative electrode active substance. CONSTITUTION:As a negative electrode active substance, are used zinc particles on whose surfaces zinc oxide layers of 10 to 50 Wt% are formed. When the zinc oxide layer on the surface is less than 10 wt%, the performance of the zinc particles is similar to that of the metallic zinc, dendrites are liable to be generated, and magnified particles are also liable to be generated. Furthermore, when the battery is overcharged, the zinc oxide layer on the surface is charged, leaving little room of chargable reserve, and sometimes generates hydrogen gas improperly. On the other hand, when the zinc oxide layer is more than 50wt%, the form of the zinc particles containing the zinc oxide layers is changed from the ball form of the metallic zinc to the column form of the crystalline zinc oxide, and the performance of the particles is considered to be similar to that of the zinc oxide. Such particles containing a higher ratio of zinc oxide disturb the permeation of the electrolyte into the zinc particles, making the conductivity lower, resulting in a lower charge efficiency and deteriorated cycle life property.

Abstract: PURPOSE:To obtain p-MOS FET with stable threshold voltage, while preventing contaminant from entering into gate insulation layer, by gettering contaminant and coating a surface of gate electrode made of p-type Si with n-type Si layer which is doped with phosphor having gettering effect through a barrier layer which prevents solid-phase diffusion of impurities. CONSTITUTION:A WSi2 layer 6A which can be barrier to impurities only on top of a p<+> type poly-Si gate electrode is placed between a p<+> type poly-Si gate electrode 5 and a phosphor-doped n<+> type poly-Si layer 7 covering the preceding electrode. In this structure, there is no WSi2 layer between the side part of the p<+> type poly-Si gate electrode 5 and phosphor-doped n<+> type poly-Si layer 7. Therefore, diffusion of phosphor and silicon occurs at this area, but there is little fluctuation of Vth due to diffusion of phosphor into the gate electrode from the area of side part of the thin p<+> type poly-Si gate electrode which takes small percentages of entire area of gate electrode.

A middle high state refers to such a state that the face (a) to be an external periphery swells out outward from the body more than the straight line (f), and the volume is expressed by a maximum dimension α. Non- orthogonal means that the straight line (Q) is non-orthogonal to the center face (g), and the angle between the straight line (f) and the center face (g) is expressed by bias angle θ from the right angle.  By manufacturing a pressure ring using this long wire 1, intermediate polishing process for finishing it into a barrel face can be omitted.
