Title: Catalytic degradation suppressing device for internal combustion engine
Inventor: MATSUMOTO HIRAKI
IPC: F02D41/14
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To retain enough exhaust emission controlling ability while suppressing the heat deterioration of a catalytic converter even under a condition that exhaust gas temperature becomes a high temperature more than a predetermined temperature. SOLUTION: When an internal combustion engine 10 is operated under a high rotation and a high load, an air-fuel ratio of exhaust gas led to flow into a first catalytic converter 22 is alternately periodically shifted to a rich or lean side so as to be purposely departed from the air-fuel ratio window of the theoretical air-fuel ratio of exhaust gas, therefore, purifying reaction in the first catalytic converter 22 is suppressed, and the heat deterioration of a catalyst by heat of reaction is prevented.  At a point of time when the air-fuel ratio of the exhaust gas after being passed through the first catalytic converter 22 is led to flow into a second catalytic converter 24 by the straightening and mixing action of exhaust gas, a variation amount to the rich or lean side is set so as to retain the inside of the air-fuel ratio window of the theoretical air-fuel ratio of exhaust gas, therefore, enough exhaust gas controlling ability can be exhibited by the second catalytic converter 24.

Title: Electrode structure for thermal head
Inventor: KATO TAKAYUKI
IPC: B41J2/345
Filed: 1989-01-09
Abstract: PURPOSE:To prevent a common electrode film from etching and a recording sheet from damaging by providing an electrode conductor film formed on a heat generating resistor film on a board and a protective film formed on the electrode conductor film. CONSTITUTION:Since a heat generating resistor film 3 is formed directly on a common electrode film 2 to narrow its area, the etching amount of the common electrode film 2 is reduced. Accordingly, the thickness of the common electrode film 2 is reduced, and the adverse influence of the etching of the common electrode film 2 to the etching of the electrode conductor film 4 can be reduced. If such an adverse influence can be reduced, the common electrode film 2 having small voltage drop can be formed, a malfunction of the heat generator due to improper etching can be prevented, and a printing of excellent quality can be performed. Since a vitreous film 6 has a smooth surface with a large thickness, a protective film 5 formed on the vitreous film 6 through the heat generating resistor film 3 and the electrode conductor film 4 is raised by one stage, and the surface of the part formed to be higher is smoothly formed. Accordingly, there is no fear of scratching a scanned recording sheet.

Title: Design taste chart
Inventor: YOSHIMOTO KAZUO
IPC: G09F7/00
Filed: 1990-01-11
Abstract: PURPOSE:To grasp similar/opposing relation in a manner easy to understand without being affected by a distant measure by arranging the respective types of design taste in an annular shape with due regard to continuity by collecting mutual distance relation so that similar ones are adjacent each other and opposing ones are opposed each other. CONSTITUTION:Design taste is divided into 8 kinds by tapes by selecting words and arranged in an annular shape. In respective explanation words divided into 8 kinds by types, adjacent explanation word groups are most similar and opposed explanation word groups are most opposed. Explanation words considered to be hardly affected by the change of a fashion or an age background are employed in order to clear types as the design taste. The sensitive one's values to 'thing' of people are set by gathering the results of market survey due to various research institutes over several past years and four types of A-D are determined while the higher rank-lower rank concept with explanation words is considered. Four types are 'quality serious consideration' of A, 'rationality serious consideration' of B, 'fashion serious consideration' of C and 'fenovation serious consideration' of D. The cultural and social living sense of a consumer is also calculated in 'rising intension' and 'fashion intension'.

Title: Low-voltage operating oscillator
Inventor: JEAN PIERRE WATTENHOFPER
IPC: H01L21/8238
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To enable a CMOS transistor to operate on a very-low power supply voltage by a method wherein the source.drain junctions of a few resistors are forward biased so as to limit currents which flow through the junctions respectively. SOLUTION: The source-drain route of a transistor M10 is connected to a resistor R3 in series between a terminal VDD and a line L1 , and the gate is connected to the line L1 . A node N5 located between the drain of the transistor M10 and the resistor R3 is connected to the tab B of a transistor M9 . The tab B of the transistor M10 is connected to a terminal VDD. When a voltage VDD becomes higher than the threshold voltage of the transistor M10 , the tab of the transistor M9 is quickly connected to a terminal VDD, and therefore, a transistor Q2 is turned non-conductive. In this case, the change in the frequency of an oscillator is less than four times the change in the power supply voltage. Therefore, a CMOS transistor is capable of operating on a low-threshold voltage.
