Title: Ignition detection device
Inventor: SAWAZAKI NORIYUKI
IPC: F02P3/045
Filed: 1994-03-24
Abstract: PURPOSE:To reduce an effect of surge voltage to a monolithic IC by providing the device with a level shift circuit, a comparator outputting a signal with shifted detected voltage compared with reference voltage, and with a clamp circuit which restrains the power supply voltage of the comparator from being fluctuated, and protects the comparator from inputting. CONSTITUTION:A voltage value that a voltage drop due to detected resistance R1 and R4 is subtracted from battery voltage VB, is applied to the reversal input terminal of a comparator COM, and a voltage value that a voltage drop due to a resistance R3 by constant current and reference voltage Vepsilon are subtracted from battery voltage VB is applied to the non-reversal input terminal of the comparator. When applied voltage at the reversal input terminal is lower than applied voltage at the non-reversal input terminal, a comparison signal in an H level is outputted, and when load current I does not flow because of the failures of ignition circuits 3A and 3B, a comparison signal in an L level is outputted. Furthermore, when the whole of voltage level is temporarily raised, a clamp circuit CL limits voltage to a monolithic IC1A to clamp voltage, so that an effect of surge at high voltage is thereby reduced.

Abstract: PURPOSE: To simplify the constitution and shorten the processing time, by utilizing the counting means to store the reading data of plural pattern detecting means successively into a memory means in the judgment of length of banknote.  
     CONSTITUTION: In response to detection of a banknote 11 by banknote detecting means 171, 172, a counting means 3 counts the pulse signals proportional to the transfer speed of the banknote 11.

Title: Exhaust particulate purifying device for internal combustion engine
Inventor: KOI RYOJI
IPC: F01N3/023
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To perform the excellent regeneration of a filter without needing a long time for regeneration and the increase of an amount of a feed power even on an operation condition that an exhaust gas temperature is especially low during idling. SOLUTION: A catalyst converter 2 is arranged upper stream of a flow of exhaust gas from a catalyst carrier filter 3 arranged in the middle of the exhaust gas flow passage of the internal combustion engine and collecting fine particles contained in exhaust gas. A partial heating heater 21 to electrically generate heat and partially activate the catalyst of a catalyst converter 2 is mounted on the catalyst converter 2. When the filter 3 is regenerated on an operation condition having an exhaust gas temperature lower than a catalyst activated temperature, the partial heating heater 21 is energized to partially activate a catalyst converter 2. Further, unburnt fuel is fed in an exhaust flow passage 1, situated upper stream from the catalyst converter, by a fuel injection valve 4 and oxidized by an activated catalyst.  Since a fuel feed amount is controlled to a small amount enough to allow maintenance of an activating state by the activated catalyst until the active state of the catalyst is stabilized, a device temperature is not lowered and thereafter through the increase of a fuel feed amount, an activated region is enlarged to a whole.

Title: Dental examination mirror
Inventor: USUI MASAYOSHI
IPC: A61B1/253
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a dental examination mirror with a built-in light illuminating means, which is subjected to no cloud in the oral cavity and requires no other radiation of illuminating light. SOLUTION: A microbulb 10 in an examination mirror part 8 generates light and heat to make other illuminating light unnecessary. A cloud by a patient's expiration is prevented by heating an oral mirror 12. Adjusting the illuminating light angle to eliminate shading by a hand and cleaning the oral mirror 12 are unnecessary to allow a doctor to be intent on examination to exactly examine a patient's affected part in a short time. After examination is completed, the whole main body (or the examination unit 1 detached from the holding handle 3) can be simply and easily treated as it is by heating in an autoclave or dipping into sterilizing liquid without damaging parts in the examination mirror 8 and a battery in the holding handle 3 by heating or corroding.  The holding handle is mounted on a charging unit in when not in use so as to usually charge a battery 13 to prevent to make examination unable by lack of power supply to the microbulb 10 in examination.

Title: Wall material for high vacuum apparatus
Inventor: KAWACHI MASAYUKI
IPC: C22C21/00
Filed: 1984-03-23
Abstract: PURPOSE:To increase the maximum degree of vacuum attained by regulating the gas content of an Al material as a wall material for a high vacuum apparatus so as to reduce an increase in the pressure due to the movement of high energy corpuscles. CONSTITUTION:An Al or Al alloy ingot is formed by vacuum degassing and casting or by melt casting by which degassing is carefully carried out by blowing gaseous Ar and Cl2. The gas content of the formed ingot is regulated to <=0.1cc, preferably <=0.05cc per 100g. The ingot is extruded to obtain a wall material for a high vacuum apparatus. Other Al material as a base material may be clad with the extruded material as a shell material. The pressure of the resulting wall material for a high vacuum vessel is hardly increased after irradiating electron beams on the material, so when a vacuum chamber is manufactured using the wall material, a very high degree of vacuum is attained.

Filed: 1978-05-10
Abstract: PURPOSE:To eliminate noise without the lowering of resolution by inserting two filters, where delay characteristic is flat and amplitude characteristic is square sine and square cosine, to the input stage in the noise eliminating circuit for video signals. CONSTITUTION:In case that slice circuit 34 does not exist and the gain from the first filter 31 to adder circuit 35 is adjusted to 1 by level adjustment equipment 35, the I/O transfer characteristic of the circuit having the first filter 31 and the second filter 32 has only a term of phase, and signals applied to input terminal 30 are only delayed without waveform distortion. Here, slice circuit 34 itself does not indicate delay characteristic, and waveform distortion is generally dominated by delay distortion, so that waveform distortion can be prevented due to the existance of slice circuit 34, and only noise components are eliminated by slice circuit 34 effectively.
