Title: Production of polyvinyl acetal resin
Inventor: KORI TOMOYUKI
IPC: C08F8/28
Filed: 1993-01-19
Abstract: PURPOSE:To produce a polyvinyl acetal resin having stable quality by preventing the resin particles from agglomerating, coalescing, and forming larger particles without any influence on the physical properties, such as heat stability and transparency, of the resin. CONSTITUTION:A method for producing a polyvinyl acetal resin by reacting polyvinyl alcohol with aldehyde in the presence of an acid catalyst and neutralizing a slurry of the deposited resin particles with alkali, wherein the reaction, the deposition of the resin particles or the neutralization is effected in the presence of a water-soluble polyether-modified silicone oil. The silicone oil prevents the resin particles from agglomerating, coalescing and forming larger particles and, even when it remains in the resin particles, does not affect the physical properties, such as heat stability and transparency, unlike the conventional methods wherein a surface active agent such as sodium lauryl sulfate is used.

Title: Semiconductor integrated circuit device
Inventor: MATSUO RYUICHI
IPC: G11C17/00
Filed: 1987-01-14
Abstract: PURPOSE:To increase the discharging speed of a common bit line and to realize a high-speed operation of a semiconductor integrated circuit, by setting the threshold voltage of an N-type transistor TR of a NAND memory at a level lower than the threshold voltage levels of N-type TRs at the periphery. CONSTITUTION:In a mask ROM device using a NAND memory, the threshold values of N-type TRs Q10'-Q13', Q15'-Q18', Q19', Q21', Q22' and Q24'-Q28' are set at levels lower than Vth of an N-type TR of a peripheral circuit and higher than 0V. In other words, an N channel type TR is obtained with low threshold value (Low Vth). In such a way, the threshold voltage Vth of an N channel TR of the NAND memory is set at a level lower than the voltage Vth of a peripheral N channel TR. Thus the ON resistance of the NAND memory is reduced and the load of a bit line is reduced. As a result, the discharging speed is increased to a GND from the bit line via the NAND memory. Then the access time is shortened.

Abstract: PURPOSE:To eliminate a continuous communication error by changing a time till the re-use of a radio control channel at random when plural communication errors take place in the radio control channel at the arrival of a call to a trunk line with respect to plural connection devices. CONSTITUTION:When a communication error takes place continuously from plural connection devices B using a same radio control channel simultaneously, a random number generating circuit 8 generates a random number.

Title: Optical recording medium
Inventor: OGAWA KOUICHI
IPC: G11B7/2433
Filed: 1982-01-22
Abstract: PURPOSE:To form a hole with the excellent SN ratio in a laser device having a small output, by making the thickness of a transparent material layer relating to an information writing optical disc device equal to a value obtained by dividing 1/4 of the optical wavelength used for the information writing by the refractive index of a material. CONSTITUTION:In irradiating a laser beam from a recording material layer 4 in a figure, the irradiated laser beam transmits the layer 4 and a transparent material layer 5 and is reflected at an optical reflector 2, and since the thickness of the layer 5 is taken as a value of prescribed condition, the reflected laser beam is in resonance in the layer 5 to produce a partial temperature rise. Thus, the heat produced in the layer 5 is delivered to tellurium forming the layer 4 to melt it locally and the layer 5 itself reaches the sublimation point partly. The hole is formed by pressing out the molten part of the layer 4 with a high pressure vapor of a copper phthalocyanine produced with the sublimation downward.
