Title: Noise resistance evaluation method
Inventor: TANIGAWA YUSUKE
IPC: G01R31/26
Filed: 1990-04-27
Abstract: PURPOSE:To achieve quantitative evaluation by connecting a radio wave generating circuit for connecting an antenna and a power supply to a tester and providing the antenna at any one terminal of an IC. CONSTITUTION:A tester 2 gives a signal waveform A to any terminal where an antenna 5 of an IC 1 is provided. Then, a radio wave generating circuit 3 which receives a pulse B converts it to a radio wave which can change the amount of radio wave at a voltage source 6, and the radio wave is propagated from an antenna 4 to the antenna 5. This radio wave is a noise. When the occurrence results in confirmation of malfunctions such as deviation of electrical characteristics of the IC 1 as compared with an expected timing or no execution of expected functions, occurrence of malfunction of the IC 1 is displayed by the tester 2. Then, if no malfunction results, voltage of the voltage source 6 is varied, this operation is repeated until malfunction occurs, and voltage of the voltage source 6 when the IC 1 malfunctions for the first time represents noise resistance of the IC 1.

Title: Graphite material for electrode and lithium ion secondary battery using it
Inventor: OBARA HIDEHIKO
IPC: H01M10/0566
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To increase the reversible capacity of a battery and to keep high capacity in rapid charge/discharge by setting the sum of the separation quantity of CO and that of CO2 due to temperature rise between specific temperatures to a specified value, and by allowing amorphous carbon to reside on a surface. SOLUTION: The sum of the separation quantities of CO and CO2 of this graphite material due to temperature rise from 25 deg.C to 800 deg.C is 5-100 μmol/g. Since the introduction of an oxygen-containing functional group is sufficient, an electrolyte and an electrolytic solution are reduced by lithium ions in utilizing it for a negative electrode, so that an interfacial film developed on the surface is stabilized, and irreversible capacity is not increased. Preferably the half-value width of a peak of 1570-1620 cm-1 in an argon laser Raman spectrum is 20-40 cm-1, and the R value that is a ratio of the peak intensity, of 1350-1370 cm-1 to this peak intensity is 0.2-2.0. Amorphous carbon on the surface is formed by a mixing baking method with an organic substance or a CVD method.  The graphite material preferably introduces the oxygen-containing functional group into the surface during surface treatment by the user of fluorine, ozone or nitric acid.

Title: Elastic surface wave device
Inventor: WAKAMORI SATOSHI
IPC: H03H9/145
Filed: 1986-05-21
Abstract: PURPOSE:To enable a phase difference between a direct wave and a surface wave to be changed without changing the pattern and the arrangement of an electrode, by forming a surface wave phase correcting electrode having a desired film thickness, between an input electrode, and an output electrode. CONSTITUTION:A surface wave phase correcting electrode 3 is provided between an input electrode 1, and an output electrode 2. A surface wave 4 excited by the input electrode 1 passes under the surface wave phase correcting electrode 3, and arrives at the output electrode 2. A relation VO>VM exists between a surface acoustic velocity VO in a free wave, and an acoustic velocity VM in an electrode part, and also, VM is varied by the film thickness of the electrode, and the thicker the film thickness, is the slower the speed. Therefore, by varying the film thickness of the phase correcting electrode 3, it is possible to change the delay time (tau) of the surface wave, and to control the phase difference between the direct wave, and the surface wave.

Title: Method for coding image signal
Inventor: ANDO ICHIRO
IPC: H04N19/132
Filed: 1990-04-26
Abstract: PURPOSE:To reduce the coding variable of a quantizing value without deteriorating picture quality by comparing a threshold value with the absolute value of an orthogonal transformation coefficient, and when the coefficient is smaller than the threshold value, executing processing for converting the coefficient to '0'. CONSTITUTION:A forecast errors from a forecast image are divided into blocks, orthogonal transformed for each block, each of the obtained orthogonally transformed coefficients is quantized by a previously determined quantization step group Q, and then the quantized value is coded. Each quantization step for each orthogonally transformed coefficient in the group Q is multiplied by a value (a)>1/2 to find a threshold group SA, the absolute value of each orthogonally transformed coefficient is compared with the threshold value of its corresponding threshold group SA, and when the former is smaller than the latter, the coefficient value is set to be '0'. In the process for coding the forecasting error of an image formed between reference images, coding errors are not accumulated. Consequently, the coding variable of a quatized value can be reduced without deteriorating the picture quality.

Title: Semiconductor device and manufacture thereof
Inventor: MINAMI KENJI
IPC: H01L21/822
Filed: 1982-07-02
Abstract: PURPOSE:To suppress the occurrence of local breakdown at the periphery of a protected impurity regions and to improve surge withstanding voltage, by forming a low concentration impurity region, which has the same conductive type as that of a high concentration impurity region, so as to surround and to contact with the vicinity of the ohmic contact part of at least an input or output wiring layer in the high concentration impurity region. CONSTITUTION:A low concentration impurity region 15 is formed in the vicinity of the ohmic contact part of an input wiring part 19, which is most liable to cause breakdown when a surge voltage is supplied. A junction which causes the breakdown at this part is an n<->/p<+> junction between the low concentration impurity region 15 and a channel stopper region 13. Since the breakdown voltage is higher than that of the conventional n<+>/p<+> junction, the breakdown that is locally occurs at this part is suppressed. Since the sheet resistance of the n<-> type low concentration impurity region 15 is very high, the current flowing through the low concentration impurity region 15 is restricted by said high resistance value, even though the local breakdown occurs at this part.

Title: Interruption control system for digital audible signal tone
Inventor: OGAWA YASUNORI
IPC: H04M19/02
Filed: 1987-05-12
Abstract: PURPOSE:To prevent the generation of noise in intermitting an audible signal tone by devising the titled system such that an audible tone data is switched in detecting the audible signal tone is a silence data. CONSTITUTION:An address control means 200 rewrites a read address stored by a time slot control memory 100 when a silence data detection circuit 209 detects it that the audible signal tone TN is a silence data. Since the read address in the time slot control memory 100 is rewritten so long as the audible signal tone TN is a silence data, the sudden change of the audible signal tone TN from a large amplitude is prevented. Thus, in case of the decoding in a digital exchange, the generation of transient oscillation being a cause to the noise is avoided.
