Abstract: PROBLEM TO BE SOLVED: To forcibly avoid a speech during driving without the need for operation by the user by providing an output of an infrared ray signal to form a control area and detecting it when a mobile radio terminal outputs a radio wave for a communication channel in the control area so as to interrupt the communication channel. SOLUTION: A detection section 4 detects a driven tire and presence of setting of a side brake so as to discriminate whether or not an automobile is driven based on the detection. In the case that the automobile is driven, a speech controller 1 sends an infrared ray control signal and transits a detection state of a voice speech signal 22 transmitted/received by a mobile radio terminal 2 in the area with a radio base station 3.

Title: Semiconductor memory
Inventor: HONMA NORIYUKI
IPC: G11C11/34
Filed: 1983-12-28
Abstract: PURPOSE:To improve the strength of resistance to alpha-rays without impairing high speed property by connecting a resistance to an emitter, and connecting the other end of the resistance to the voltage source, thereby obtaining the holding current. CONSTITUTION:A resistance 10 is connected to the emitter of a memory cell in series to prevent current hogging and the resistance is connected to a holding current line IL. The holding current line IL is connected to a constant voltage source 20. The holding current which flows to each memory cell is decided by the electric potential difference between a word line WL and the holding current line IL, and the resistance 10, and the holding current is not affected by other memory cells. Since current hogging does not occur at all, the memory cell becomes stronger remarkably against the soft error due to alpha-ray. Since the word line WL becomes to have a high electric potential after the word line is selected, the electric potential difference between the word line and the holding current line IL with constant electric potential becomes larger, each memory cell has larger current than the current at the holding time, and the falling of the word line can be made in a high speed.

Filed: 1994-09-14
Abstract: PURPOSE: To provide a good cycle characteristic by using a lithium transition metal oxide having peaks at 285eV and 289eV by XPS measurement of CIS spectrum as a positive electrode active material in a lithium secondary battery. CONSTITUTION: On the surface of a lithium transition oxide used as a positive electrode active material, H2 O is adsorbed in oxygen and an OH group is produced, and an electrolyte is oxidized and decomposed by the OH group to deteriorate the cycle characteristic in charge/discharge. By chemical adsorption of a CO3 group on the surface of a positive electrode active material, reaction of the active material with the electrolyte is retarded. In the preferable active material, peaks are shown at 285eV and 289eV by XPS measurement of CIS spectrum, and the ratio of both peaks is 0.4-0.9. A manufacturing process in which the lithium transition metal oxide is let to stand in a CO2 gas-containing atmosphere for a specified time is preferable. The chemical adsorbing layer is formed only on the uppermost layer surface of the positive electrode material.  This method is more effective when lithium nickel oxide is used.
