Title: Cylinder pulse counting device
Inventor: HAMAOKA HIROMI
IPC: G11B5/55
Filed: 1982-03-31
Abstract: PURPOSE:To exactly count a cylinder pulse even if noise enters into a position signal, by measuring a period of each pulse in order, forecasting a time when a new pulse is inputted, and making a pulse inputted at this time effective. CONSTITUTION:A microprocessor 4 measures a time from the time at the leading edge of the (r)-1-th pulse, and supplies a reset signal to an FF3 at the point of time when said time passes through 90% of the time extending from the time of rise of the (r)-2-th pulse to the time of rise of the (r)-1-th pulse. After that, properly speaking, the (r)-th normal pulse is inputted to the set side of the FF3, but in this case, a pulse by a noise is inputted to the input side of the FF3. Accordingly, a signal outputted from the FF3 becomes high at the leading edge of the pulse by noise, and a count value goes to (r). In accordance with this count value (r), the following (r)+1-th pulse is counted in the same way.

Title: Gas leak detecting method
Inventor: OTANI TSUTOMU
IPC: G01M3/28
Filed: 1993-03-12
Abstract: PURPOSE:To make gas circuit breaking and alarm sounding achievable in judging a gas leakage downstream more than a gas meter so accurately in a short time by installing this gas meter, a gas pressure sensor and correlative arithmetic circuit respectively. CONSTITUTION:A gas meter detects a gas flow rate and a gas pressure sensor detects the extent of gas transfer pressure. These detected values are inputted into a correlative arithmetic circuit which will in no case perform its correlative ovation in the case where the gas transfer pressure is constant (provided that there is more or less the range of fluctuations), and the flow rate alone is changed. When the gas transfer pressure is changed to sane extent and there is recognized a correlationship between both variations of the gas transfer pressure and the gas flow rate, it is so judged that there is a gas leakage, transmitting a signal to a gas leakage judging circuit (an arithmetic and inference mechanism of pressure and flow fluctuations and correlativity). In succession, when this gas leakage judging circuit judges that there is a gas leakage, gas is thus cut off, and differently a gas leakage warning is issued at the same time.

Abstract: PROBLEM TO BE SOLVED: To provide the voltage and current reference circuit which has a low temperature coefficient. SOLUTION: The voltage and current reference circuit 110 is minimized in the number of elements to reduce the area on an integrated circuit die. A band gap voltage reference 120 generates a voltage which has a low temperature coefficient. A voltage follower 130 is coupled with the band gap voltage reference 120 and generates a reference voltage corresponding to a band gap voltage. A temperature varying current from the band gap reference 120 is mirrored and supplied to the 1st electrode of the voltage follower 130. A resistance R4 is coupled between a power source terminal and the 2nd electrode of the voltage follower 130. The resistance value of the resistance R4 is so selected as to generate a current canceling the temperature dependency of the temperature varying current.  A current mirror circuit 140 receives the rest of the temperature varying current and outputs a current which is low in temperature coefficient.
