Filed: 1988-07-12
Abstract: PURPOSE:To form N-channel transistors having two kinds of thresholds without increasing processes by performing an impurity injection so as to control the threshold of an N-channel MIS transistor simultaneously with the impurity injection for controlling the threshold of a P-channel MIS transistor. CONSTITUTION:When two kinds of thresholds of N-channel MIS transistors T2a and T2b are formed, threshold adjustment impurity injections for the N- channel MIS transistor T 2b having a high threshold are performed twice simultaneously with a threshold adjustment impurity injection for the N-channel MIS transistor T2a having a low threshold as well as with a threshold controlling impurity injection for a P-channel MIS transistor T1. This system allows the transistor T2b to perform P-type impurity injections twice, and then, its impurity concentration is obtained by adding together the first and second impurity concentrations. As a result, the impurity concentration is higher than that of single impurity injection performed by the transistor T2a. Moreover, the number of processes is not different from the conventional one, that is, a CMOS process of the N-channel transistor having a single threshold.

IPC: H04N1/32
Filed: 1988-07-14
Abstract: PURPOSE:To suppress the production of a transmission error at transmission of picture information by setting the MODEM training criterion toward a tighter condition in the case of executing the picture information transmission utilizing a picture storage function. CONSTITUTION:A system control section 1 sets a high speed MODEM function of a MODEM 10 at MODEM training so as to discriminate whether or not the picture information transmission uses a picture storage function (memory transmission). When the result of discrimination is YES, the value of a specified value EBT being a criterion of the result of MODEM training is set to '10' and when NO, the value is set to '15'. That is, in the case of the transmission utilizing the picture storage function, the result of training is discriminated tighter. Thus, since the picture information transmission speed is set in a decreasing direction in the case of the transmission utilizing the picture storage function more than the other cases, the production of transmission error at the picture information transmission is suppressed.

Title: Surface acoustic wave filter
Inventor: TAGAMI TOSHIO
IPC: H03H9/145
Filed: 1991-07-15
Abstract: PURPOSE:To improve humidity resistance without damaging the characteristic of the surface acoustic wave filter (SAW-F) by forming an SiO2 film having specified thickness at the top of an interdigital electrode. CONSTITUTION:This SAW-F is equipped with Cr 1 to be an adhesive layer on the base, Al-Cu alloy 2 adding Cu to Al as an electrode layer, and SiO2, film 3 to cover the surface of the Al-Cu alloy 2 as a protecting layer to protect the Al-Cu alloy 2. Namely, the Al-Cu alloy 2 constituting the interdigital electrode is covered with the SiO2 film 3 having thickness 100Angstrom -1000Angstrom , and a pattern is formed by lift-off. When the SiO2 film 3 is thick, the characteristic is degraded since the surface acoustic wave vibration of the interdigital electrode is blocked and when the thickness is less than 1000Angstrom , the level of a loss is not reduced so as to cancel the deviation of a frequency by making the film of the Al-Cu alloy 2 thin. When the SiO2 film 3 is too thin, however, a humidity proof effect is lowered and therefore, the thickness more than 100Angstrom  is required.
