Title: Semiconductor memory device
Inventor: KAGAMI AKIHIKO
IPC: G11C11/401
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce the layout area of a semiconductor memory device of a split word driver system by using the output of the main word driver for redundancy, in each block constituted with a memory array as a unit, also as a block selecting signal indicating the selective activation in a block unit. SOLUTION: A block selected-circuit BSL inputs a redundancy main word signal RMWL' making an internal booster voltage a high level, and outputs it as a block selecting signal making a power source voltage a high level. A data amplifier is selectively activated corresponding to each block selecting signal, amplifying and outputting the data in a block unit. As a result, since each circuit constituted in block units such as a data amplifier is selectively activated, there is no need to lay out internal address signal wiring corresponding to an input address signal; therefore, the layout area can be reduced.

Title: Edge for speaker
Inventor: MURATA KOSAKU
IPC: H04R7/20
Filed: 1985-05-20
Abstract: PURPOSE:To obtain a speaker with little nonlinear distortion by constituting the speaker in a manner that the middle part of a formed component which is the titled edge consisting of an elastic cylinder of thin rubber is folded and the periphery of one end of the said edge is bonded with a diaphragm and the other with a frame or fixed end. CONSTITUTION:When a current flows through a voice coil 10 placed in a uniform magnetic field, the voice coil generates magnetic force in vertical direction, and vibrates according to the amount of the current. This vibration is properly transmitted to the diaphragm 8, and is emitted in form of sound wave. The edge 6 supports the diaphragm 8, and able to keep the diaphragm 8 at all time in the center. When vibrating, the edge 6 which is the formed component consisting of an elastic cylinder of thin rubber moves its folding in the middle against a large amplitude, accordingly provides an excellent linearity. The said edge lowers the distortion by approximately 20dB per 1W input at 100Hz in comparison to a conventional speaker using a roll edge.

Filed: 1988-04-30
Abstract: PURPOSE:To be able to supply efficiently a wafer with secondary electrons to prevent efficiently the wafer from being charged, by setting a d. c. power supply which makes the potential of a disc positive against a secondary electron emitting means. CONSTITUTION:Between a disc 4 and a neutral cup 14 as a secondary electron emitting means is set a d.c. power supply 32 which makes the potential of the disc 4 positive against the cup 14.

Title: Alkaline-zinc storage battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M2/16
Filed: 1985-05-20
Abstract: PURPOSE:To unify the held quantity of an electrolyte between a zinc electrode and a positive electrode, by prescribing the liquid holding ratio of a non-woven fabric as a separator to uniformly distribute the electrolyte in the separator even in a system in which the electrolyte is limited. CONSTITUTION:A non-woven fabric, whose potassium hydroxide solution holding ratio at room temperature is 80-150%, is used as a separator between a zinc electrode and a positive electrode to uniformly distribute an electrode in the separator even in a system in which the electrolyte is limited so as not to be free. The electrolyte is thus uniformly infiltrated and held between the zinc electrode and the positive electrode. As a result, the decrease in the capacity of a storage battery is reduced in its charge/discharge cycle to enhance the cyclic operating properties of the battery to lengthen its life.

Title: Thermal head and manufacture thereof
Inventor: YOSHIIKE NOBUYUKI
IPC: B41J2/335
Filed: 1986-05-12
Abstract: PURPOSE:To lower the thermal conductivity of an enamel layer, enhance a heat- insulating effect and reduce power consumption, by covering the surface of a metallic substrate with the enamel layer, and providing a Pb-containing layer at the surface of the enamel layer. CONSTITUTION:A substrate 1 is formed from stainless steel, iron or the like, and a glass ceramic layer 2 constitutes an enamel layer. Metallic lead (Pb) is vacuum- deposited on the surface of the enamel layer 2 in a thickness of 1,000Angstrom -3mum under a vacuum degree of 1-5X10<-5>Torr to provide a Pb-containing layer 3. Next, the substrate is heated (to or above 750 deg.C) in air, whereby metallic lead is brought into an oxidized state such as PbO, and Pb is thermally diffused into the enamel layer 2, resulting in that a surface part of the enamel layer 2 is converted nearly to a low melting point lead glass layer 4. Thus, a Pb-rich glass layer is newly provided at the surface of the enamel layer. Resultantly, the surface of the enameled substrate can be made smoother, and scatter of resistances of dots in a thermal head can be reduced to + or -5% or less. In addition, pinholes can be prevented from being formed in the enameled substrate, insulation between the enamel layer and the metallic substrate can be enhanced even with a thin enamel layer, and heat generating efficiency can be enhanced because of the low thermal conductivity of the lead glass.

Title: Level shifter and level shift driver
Inventor: JIYON SUTEFUAN OOSUTEIN
IPC: H03K19/0185
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a level shifter which interfaces between a low-voltage logic device and a high-voltage logic device. SOLUTION: A level shift driver shifts a low magnitude logical signal to a high magnitude logical signal. When the driver shifts the logical signal, a high voltage Vdd+ related to the high magnitude logical signal is prevented from being fed back to a logic device related to the low magnitude logical signal. An input terminal receives the low magnitude logical signal. The channel of an N-MOSFET 34 is connected between the input terminal and a output terminal and the gate of the MOSFET 34 is connected to a low power supply voltage Cdd . A latch network 50 which is biased by a high power supply voltage represents the low magnitude logical signal, but has one node of a latch connected to the output terminal which gives a high magnitude output signal formed of the high power supply voltage.

IPC: C03B37/012
Filed: 1982-06-23
Abstract: PURPOSE:To obtain an optical fiber which prevents twisting during drawing and enables the easy identification of the axial direction of polarization in the stage of connection by forming the outside shape of the support part in the outermost part into an elliptical shape having the long and short axes in the direction where the fast axis and slow axis of the core coincide. CONSTITUTION:The outside shape of a support 1 made of quartz glass is formed to an elliptical shape resembling to the outside shape of a jacket 2, and the long axis and short axis directions of the outside shape of the support 1 coincide respectively with those of the jacket 2. Such optical fiber for maintaining the plane of polarization enables the immediate estimation of the shape of the jacket 2 and the axial direction of polarization of a core 4 from the shape of the support 1; therefore, the easy matching of the directions of polarization and the optical transmission with good efficiency are made possible. In the case of drawing the fiber, the outside diameter of the optical fiber is measured in two directions, horizontally and vertically, and the fiber is monitored so as not to rotate, whereby the optical fiber for maintaining the plane of polarization is easily obtd.
