Title: Production of sintered material having high toughness
Inventor: ADACHI SEIJI
IPC: C04B35/80
Filed: 1987-05-08
Abstract: PURPOSE:To obtain a sintered material having high toughness, in a short time in high production efficiency, using a pressurized self-combustion sintering proc ess, by dispersing a rod like or fibrous component resistant to fusion and decom position by ignition reaction into the formed raw material. CONSTITUTION:Raw materials (e.g. a mixture of metallic titanium powder and carbon black) necessary for the production of a sintered article by pressu rized self-combustion sintering process are mixed with a rod like or fibrous component (e.g. silicon carbide whisker) resistant to fusion and decomposition in the combustion reaction. The mixture is molded to obtain a molded article containing dispersed rod-like or fibrous component. The molded article is ignited under pressure to start the combustion reaction to effect the simultaneous synthe sis and sintering by the heat generated by the combustion process to obtain the objective sintered article having high toughness. The energy of the produc tion process can be remarkably saved and the production time can be shortened.

Title: Manufacture of alkaline cell
Inventor: FUJI KENJI
IPC: H01M4/12
Filed: 1988-05-11
Abstract: PURPOSE:To make it possible to manufacture a stable alkaline cell by mixing a gelatinized zinc powder and a gelling agent in an inert gas, and then, adding an electrolyte to form a negative electrode composite. CONSTITUTION:When a gelatinized zinc powder and a gelling agent is mixed and churned in an enclosed container, they are mixed in an inert gas, and then, an alkaline electrolyte is added. Since there is no oxygen even though the gelatinized zinc powder in mixing and churning is in the condition extremely activated, the surface of the zinc powder is not oxidized. Furthermore, by leaving it still after mixing and churning in the inert gas, the mercury covers the surface of the zinc perfectly, and the zinc powder is not oxidized rapidly even in the air thereafter. Consequently, a stable cell in respect of the inner resistance of the cell and of the display property can be obtained.

Title: Semiconductor device
Inventor: KONDOU SHIYUUJI
IPC: H01L23/60
Filed: 1981-07-20
Abstract: PURPOSE:To prevent the damage of a circuit element chip associated in a package by the influence of static electricity when the static electricity is applied to the lead terminal of the package. CONSTITUTION:The end of a lead terminal 4 is formed in a structure having a shortcircuit lead 8 at one end of a shortcircuit plate 7. The coupler 9 of the terminal 4 to the plate 7 is formed in a shape such as wedge or conical shape at the end of the terminal 4, and is constructed locally in an ultrafine coupling structure with the plate 7. Accordingly, when several bending forces are applied to the plate 7, the coupler 9 can be simply and readily broken, and the plate 7 and the terminal 8 can be separated. In this manner, since all the lead terminals are connected immediately before use, even if static electricity is applied to the lead terminal during the stock or transportation, all the leads becomes the same voltage. Thus, an accident of damaging the circuit element chip due to the production of potential difference at the chip can be prevented.

Title: Detection circuit of address transition
Inventor: KIN KEISEI
IPC: G11C11/41
Filed: 1995-05-12
Abstract: PURPOSE: To speedily generate transition of an address signal with a simple constitution by generating a pulse with a transition detection signal and converting it into a signal of MOS level. CONSTITUTION: When an address bit signal Ai with a waveform A is applied to the gates of PMOS and NMOS transistors(TR) 41 and 42 to cause low-to-high or high-to-low transition, both the TRs 41 and 42 turn on when the threshold values of the TRs are reached, a current flows from a power source Vcc to the ground, and a voltage waveform B determined by the value of a resistance R appears at a node N1 and is applied to an inverter 60. At this time, the maximum value of the voltage is set larger than the MOS threshold value by adjusting R, and then a waveform C is obtained as the output of the inverter 60 and inverted by an inverter 70 to obtain a waveform D. Thus, a pulse of high level is generated each time the address signal has transition to make it possible to omit a NAND gate, and an address can speedily be detected by eliminating the delay time due to the gates.

Filed: 1993-05-17
Abstract: PURPOSE:To obtain desirably the subject resin while avoiding problems caused by a conventional catalyst by polymerizing an aromatic dihydroxy compound with a diaryl carbonate by melt polycondensation in the presence of a glass filler as a catalyst. CONSTITUTION:This production method comprises polymerizing an aromatic dihydroxy compound (a) with a diaryl carbonate by melt polycondensation using a glass filler (e.g. chopped glass strand) as a catalyst in an amount of 0.1wt.% or larger based on the compound (a). The method is free from such problems caused by a conventional catalyst as induction and acceleration of a side reaction, necessity for a long polycondensation time, and catalyst inclusion in the resin. Thus, an aromatic polycarbonate resin containing no chlorine atom can be easily produced through melt polycondensation. By regulating the amount of the filler, this resin can be obtained directly as a filled resin having a desired glass filler loading.
