Title: Box separator and lead storage battery
Inventor: MORII SATORU
IPC: H01M2/18
Filed: 1990-11-27
Abstract: PURPOSE:To prevent a battery capacity from lowering due to falling of active material and obtain a battery with low internal resistance by giving box-like processing to a laminate with a glass mat arranged between a pair of porous synthetic resin sheets or films. CONSTITUTION:Because pressure can be applied to a plate 2 through resiliency from a glass mat 5, anode active material can be restrained from falling off the plate 2. Because a porous synthetic resin sheet or film has almost no gas permeability, no oxygen or hydrogen gas permeates or resides inside the glass mat 5 which is arranged between a pair of porous synthetic resin sheets or films 4A, 4B, while internal resistance is not greatly increased if the glass mat 5 is used. It is thus possible to restrain anode active material from falling off the plate 2, prevent oxygen or hydrogen gas from residing inside the glass mat 5 and obtain a battery with low internal resistance.

Title: Bit-line sense amplifier and its controlling method
Inventor: JO TEIGEN
IPC: G11C11/419
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To enable a bit-line sense amplifier to stably operate at a high speed even under the worst condition by compensating the offset of the amplifier resulting from the mismatch between transistors. SOLUTION: Offset compensation and sensing are accomplished by using inverters 41 and 42 respectively provided with transistors NB1 and PB1 and NB2 and PB2. The pull-down control signals GAi of the inverters 41 and 42 become 'high' only when the output GYi of a column is activated at the time of reading data so as the eliminate the unnecessary power consumption of a whole inverter sense amplifier array. At writing time, the control signals GAi are inactivated when the control signals GAi are 'low' and the pull-up driving signals (PD) of the inverters 41 and 42 become floating states and set the inverters 41 and 42 to inactive states. An offset compensating signal, on the outer hand, is activated to make data transmission to a bit line from a data bus possible when the control signals GZi are 'high'.

Filed: 1990-11-27
Abstract: PURPOSE:To improve communication efficiency by inhibiting a call incoming to a terminal, which can not connect a data terminal since only at voice, function is provided, among terminals housed at a point S of an extension when information transmission ability is unlimited digital for the incoming call from an ISDN. CONSTITUTION:When a main control part 126 detects the call incoming from an ISDN T-point interface 108, a transmission ability information element is extracted from call setting information, and a processing is branched. While referring to a memory 126M, when information transfer ability is 3.1kHz audio and the high-order layer characteristic identification of a high-order layer consistency information element is G3, it is judged whether the extracted S-point telephone terminal is a G4 FAX equipped with the G3 function or not. When the terminal is the G4 FAX having no G3 function or an ISDN telephone set equipped with a telephone function only, the incoming call to the terminal registered on the memory 126M is inhibited. Thus, communication efficiency is prevented from being lowered by terminating the call to the terminal disabling designated communication.

Title: Circuit built-in photodetector
Inventor: MAEDA AKIYUKI
IPC: H01L27/14
Filed: 1988-12-23
Abstract: PURPOSE:To enable a photodetector of this design to operate at a high speed and to be high in sensitivity by a method wherein the photodetector is formed on the protrusion of a semiconductor substrate and a second conductivity type well is provided onto a flat part to form a circuit element. CONSTITUTION:N<+>-type buried layers 2 are formed on a photodetector section forming predetermined region and a circuit element forming predetermined region of the surface of a P-type semiconductor substrate 1 respectively, and an epitaxial layer 3 of high resistivity is formed on the whole surface, where the thickness of the layer 3 is so optimized for making a photodetector operable at a high speed and high in sensitivity. Next, a circuit element section forming region of the epitaxial layer 3 is so etched to make its thickness optimized as a circuit element section. Therefore, the photodetector forming region of the epitaxial layer 3 of high resistivity becomes a thick protrusion at this stage, and the circuit element section forming region grows to be a flat section. That is, as the photodetector section is formed of a thick part of the epitaxial layer 3 of high resistivity, the photodetector can be improved in response speed and photosensitivity owing to a reduction in capacitance, and the circuit element section is formed of a thin part of the epitaxial layer 3, so that the circuit element section can be made high in response speed.
