Title: Production of ceramic fiber and coating material by infusibilizing precursor polymer by means of radiation oxidation
Inventor: SEGUCHI TADAO
IPC: C01B31/36
Filed: 1990-03-14
Abstract: PURPOSE:To produce high-strength ceramic fiber by irradiating silicon-contg. polymer fiber with ionizing radiation in an oxygen atmosphere, subjecting this fiber to heat treatment and calcinating it in an inert gas. CONSTITUTION:The precursor 1 of silicon-contg. polymer fiber (e.g. silicon carbide fiber) is irradiated with ionizing radiation in an oxygen atmosphere for radiation oxidization to form a radiation-oxidized area 2 on the surface of the precursor. Then the fiber is treated by heating to cause crosslinking due to oxidation in the radiation-oxidized area 2, where an oxidation crosslinked area 3 is formed. Then the fiber is subjected to extraction with a solvent to dissolve and remove the area except for the crosslinked area and to obtain a columnar form having a cavity 4. Then this columnar fiber is calcinated into ceramics and to obtain a columnar ceramic fiber 5. Thereby, the high- strength ceramic fiber 5 can be easily produced.

Title: Semiconductor memory
Inventor: SAKUI YASUSHI
IPC: G11C11/404
Filed: 1984-03-31
Abstract: PURPOSE:To attain the data reading and writing actions in a short access time by ion-implanting the impurities of an adverse conduction type to a substrate to a channel area of a switching MOS transistor and therefore eliminating the use of the boosted voltage for drive of a word line. CONSTITUTION:For a dynamic RAM, an equivalent circuit of a memory cell part consists of a switching MOS transistor TR1 and an MOS capacitor 2. Then the impurities such as phosphorus, arsenic, etc. which produce a conduction type adverse to a substrate are ion-implanted to a channel area of a switching MOSTR of a memory cell array. Therefore a D type switching MOSTR is obtained for the memory cell with the threshold voltage Vth equal to -3[V] or so. Thus a word line is set at voltage VDD-2Vt only in an active mode where the reading or writing is given to the storage data of a memory cell. Then the word line is set at VBB in other precharge modes. Thus a high-speed access is possible without using a boosting circuit for drive of the word line. Furthermore the reliability is improved with a semiconductor memory.

Title: Decreasing voltage detecting device
Inventor: KOMAZAWA OSAMU
IPC: H02J1/00
Filed: 1984-03-30
Abstract: PURPOSE:To improve the detection precision of a decreasing voltage by detecting a decreasing voltage detection signal from the secondary side of a constant voltage circuit. CONSTITUTION:A decreasing voltage detecting circuit 40 detects the continuity and cut-off state of a transistor TR3. Namely, when a source voltage B is high enough to obtain a constant voltage VCC, the TR3 is on and a TR4 is off. When the source voltage B drops until the constant voltage VCC is not obtained any more, the Zener voltage and Zener current of a Zener diode ZD2 drop and decrease respectively and the base-emitter voltage of the TR3 also drops. Then, the TR3 turns off and the TR4 turns on to apply an H-level signal to the inverted input terminal of the operational amplifier OP2 of a reset circuit 20 through a resistance R10. The output terminal of the amplifier OP2 is held at a level H and a reset signal appears at the reset terminal RES of a CPU. Thus, the cut-off state of the TR3 is detected from the decrease in the Zener voltage of the diode ZD2 of the constant voltage circuit 10 to detect the decreasing voltage.
