Title: Ask modulated signal demodulating device
Inventor: SATO KOTARO
IPC: H04L27/06
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the characteristic variance caused by the temperature change in a working mode even though the primary circuit part is equal to an analog circuit. SOLUTION: An arbitration circuit 11 functions only when both edge detection signal and delayed edge detection signal of an ASK modulated signal that undergone the half-wave rectification are set at logical value '1'. A counter circuit 12 outputs the count value to show the frequency of detection signals appearing within a fixed time. An upper-lower limit detection circuit 13 outputs both upper and lower limit detection signals to the circuit 11 when the number of carrier pulses reaches its upper and lower limit value per bit of the deceived data respectively in order to prevent the malfunction of the circuit 12. A comparator 14 compares the count value of the circuit 12 with its threshold. Then a JK type F/F circuit 15 is set at logical value '1' or '0' according to the comparison result of the comparator 14 and outputs the demodulated data.

Title: Molded circuit board
Inventor: TAGAMI YOSHITAKA
IPC: H05K1/03
Filed: 1988-10-28
Abstract: PURPOSE:To obtain a molded circuit board with good adhesiveness of metal plating and excellent heat resistance by blending acrylonitrile butadiene rubber and particle-shaped phenol resin composite as a filling material, to thermosetting resin. CONSTITUTION:Phenol resin curing matter may not be solved with acrylonitrile butadiene rubber during the molding period of a molded circuit board, because it is low in its heat melting property, and it shows the performance of a mere filling material. However, since the phenol resin curing matter somewhat takes place a three dimensional bridge reaction with the thermosetting resin at the molding time, the improvement of heat resistance of a molding becomes possible. The phenol resin curing matter blended therein as a filling material is activated the same as the thermosetting resin constituting the molding in the activation process for catalytic adsorption, as a result, the metal plating adhesiveness never decreases in this blend. Moreover, glass fibers or cotton cloth are blended therein in the range of not lowering the metal plating adhesiveness as a filling material excepting the particle phenol resin curing matter, thereby raising the mechanical strength of a molding.

Title: Pressure gauge
Inventor: NAKANO JIRO
IPC: G01L9/04
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To achieve a compact pressure gauge with high pressure resistance and durability. SOLUTION: A shoulder part 1c of a connector housing 1 located below the neck part 1a of the connector housing 1 is composed by a ring-shaped metal plate 101 for reinforcing the connector housing 1. The end part 3a of a sensor housing 3 is bent inward over one periphery of the outer periphery of a metal plate 101, thus composing caulking so that pressure can be nearly uniformly applied to the entire portion of a bottom surface A of the metal plate 101. Pressure being inputted from a pressure introduction hole 3b is transferred to a pressure-sensitive element 5 via a seal diaphragm 7, sealing liquid (pressure transfer medium) 13 or the like.  With this configuration, the pressure resistance strength of the shoulder part 1c of the connector housing 1 that becomes the junction part of caulking has been improved greatly, thus preventing the resin of the connector housing 1 from being deformed or damaged in manufacturing and hence preventing deformation or deflection from occurring also when measuring a high pressure.

Title: Nonvolatile semiconductor memory and its readout method
Inventor: FUKUZAKI YOSHIKI
IPC: H01L29/792
Filed: 1991-10-21
Abstract: PURPOSE:To reduce the dimension of a memory cell with no need of a source region and a selection separation transistor by making an MNOS capacitor with a drain region serve as the memory cell and by detecting charge transfer due to capacitor charge current to read out information. CONSTITUTION:A title memory consists of an MNOS structure capacitor and a drain region adjacent to it. A voltage lower than a threshold voltage in erasure state is applied to a polysilicon electrode 7 to keep the surface of a silicon substrate of the MNOS capacitor on storing charges. After precharged to 0V, an N<+> drain region 3 is separated from another circuit, and a positive voltage as high as possible is applied to the polysilicon electrode 7 over a range lower than a threshold voltage in write-in state. At this time, erasure state of low threshold voltage inverts the surface of a silicon substrate of an MNOS capacitor to cause electrons to flow from an N<+> drain region 2, resulting in a rise in potential of the N<+> drain region 3. This change in potential is detected for readout.

Patent JP-H02120033-A (JP)
Title: Building member excellent in corrosion resistance and manufacture thereof
Inventor: SUZUKI SHUNSUKE
IPC: E04C2/08
Filed: 1988-10-28
Abstract: PURPOSE:To obtain building member, which can be used under special environment over a long period of time with no development of corrosion and the like and has strength and fire resistance and is not expensive and excellent in aesthetic feeling by a structure wherein lead or lead-based alloy covering layer having specified thickness is made on both sides of steel-based sheet-like material. CONSTITUTION:The building member concerned excellent in corrosion resistance is produced by making lead or lead-based alloy covering layer having the thickness of 50-3,000mum on both sides of steel-based sheet-like material. If the thickness of the covering layer is below 50mum, the layer has fine pores even when the layer is made by pouring casting method. If the thickness of the covering layer exceeds 3,000mum, the resultant member is too heavy as ceiling material and excessive from the view point of economical efficiency. Further, if after-working such as bending or the like is necessary, trouble such as the separation of the covering layer at the bending through 90 degrees occurs. As the lead-based alloy, lead alloy containing 1.5 - 10% thin is preferable. If Sn content is below 1.5%, no uniform covering layer can be formed over the whole surface of the steel-based sheet-like material. If Sn content exceeds 10%, the corrosion of the Sn itself in alloy tends to proceed and, in addition, the resultant alloy becomes expensive.
