Title: Video signal binary-coding circuit
Inventor: FUKASE TAKAYUKI
IPC: H03K5/08
Filed: 1983-05-26
Abstract: PURPOSE:To prevent mis-reading by adding an analog delay circuit, an AND circuit and an OR circuit in addition to a peak hold circuit. CONSTITUTION:A sample-and-hold circuit 1 samples separately only a video signal from noise in an input signal IN and samples and holds it by a prescribed clock. A delay circuit 2 gives a prescribed time of delay to an analog signal A of the circuit 1 and outputs an analog signal B. An AND circuit 4 ANDs analogically the signals A, B. A peak hold circuit 3 follows a samll level of fluctuation of the peak value of the signal A and holds the peak value at large level fluctuation. An OR circuit 7 ORs analogically an output C of the circuit 3 and the signal A. A comparator 8 takes a value dividing an output E of the circuit 7 by a prescribed ratio as a reference compares an output F of the circuit 4 to binary-code. The ruggedness of the input signal is smoothed in the output F to include much black level component and to reduce noise due to dirt or the like.

Title: Electronic clinical thermometer
Inventor: KOBAYASHI TOSHIYUKI
IPC: G01K7/00
Filed: 1986-04-21
Abstract: PURPOSE:To execute a rational body temperature measurement by conjecturing a convergence temperature from an actually measured temperature soon after it has been started to take a temperature, and setting a different measurement end condition in accordance with whether this conjectured convergence temperature exceeds a reference temperature or not. CONSTITUTION:When a power source switch 4 is turned on, a CPU 7 obtains temperature information from a temperature sensor 2 at every 1sec. It is executed for a prescribed time of 5sec, and based on obtained temperature information, a convergence temperature is conjectured by a general expression of a conjecture operation, and whether a conjectured convergence temperature is higher than a prescribed temperature (for instance, 37 deg.C) which has been set in advance or not is decided. If said temperature is higher than the prescribed temperature, a decision reference value for ending the measurement is set to a small value (for instance, while a temperature rises by 0.01 deg.C in 10sec, and when said temperature is lower than the prescribed temperature, the decision reference value for ending the measurement is set to a large value (for instance, a value by which a temperature rises by 0.02 deg.C in 6sec). The measurement of a body temperature is continued until a temperature rise rate becomes lower than said decision reference value.

Title: Critical current adjusting method of skid element
Inventor: YAMADA YASUHARU
IPC: G01R33/035
Filed: 1984-05-09
Abstract: PURPOSE:To generate no variation in an adjusting value of a critical current by the influence of a residual ion, and to adjust the current to a desired correct value by using jointly an anodic oxidation and a thermal oxidation, and forming repeatedly an oxide film. CONSTITUTION:A skid element 1 is formed by laminating a thin film 3 of niobium and a resist layer 4 on a plate-shaped quartz substrate 2. In such a state, when a pulse voltage is applied from a pulse voltage source 6 in a state that an electrolyte 5 is dripped down to an exposed part of a bridge 3c, namely, a blank part 4a of the resist layer 4, the anodic oxidation advances, niobium ion and oxygen ion react and an oxide film is formed. When the film thickness of this oxide film becomes larger and an electric conductive current I goes to a set value, a comparator 9 turns off a switching circuit 8. Subsequently, the thermal oxidation is executed at the temperature of about 130 deg.C for about 5min so that the oxide film is stabilized. Therefore, a transition current value is measured by immersing the skid element 1 into extremely low temperature liquid, and the anodic oxidation and the thermal oxidation are repeated until a prescribed critical current is obtained.

Title: Valve action controller for engine
Inventor: KOMATSU HIROSHI
IPC: F01L1/08
Filed: 1989-04-13
Abstract: PURPOSE:To improve the fuel consumption by setting the valve action angle, which becomes smaller the lower the engine load becomes at a partial area, and the intake valve closing period, which becomes earlier, respectively. CONSTITUTION:A valve opening/closing period setting means 22 devides the motion area into two or more and sets the valve opening/closing period in each one. A selecting means 25 selects from the means 22 the valve opening/ closing period being set about the motion area that the detection valve of an engine load sensor 24 belongs to. Moreover, an output means 26 outputs the control quantity in accordance with the selected valve opening/closing period, and a valve opening/closing period varying mechanism 21 makes the valve opening/closing period variable according to the control quantity. Hereupon, the valve opening/closing period setting means 22 sets the valve action angle, which becomes smaller the lower the engine load becomes at a partial area, and the intake valve closing period, which becomes earlier, respectively. Accordingly, pumping loss decreases at the partial area, and the fuel consumption improves.

Title: Knocking detecting device
Inventor: TAKEUCHI KIYOSHI
IPC: G01L23/22
Filed: 1990-04-09
Abstract: PURPOSE:To detect a knocking signal with high sensitivity regardless of the positions of air cylinders by transducing vibration, which is transmitted to a head gasket made of a material with high vibration transmissivity, into an electric signal and extracting a knocking vibration component. CONSTITUTION:A cylinder head 4 is provided above a cylinder block 20 and the head gasket 21 is fitted between this cylinder block 20 and cylinder head 4. The gasket 21 is formed of the metallic material with high vibration transmissivity, e.g. stainless steel in a flat plate shape. Then the pressure vibration is propagated from the inner peripheral end surface to the outer peripheral end surface of the gasket 21. This knocking vibration is transduced by an knocking sensor 2 into the electric signal, which is inputted to a BPF 10 and outputted as a signal corresponding to the frequency of generation to an ignition circuit 15 through a comparator 11 and an integrator 14 to adjust the ignition period of an ignition plug 8. The vibration transmissivity of the gasket 21 is high, so the sensor 22 is not affected by the distance to each air cylinder and the knocking vibration can excellently be detected.

Title: Mechanical seal device
Inventor: TAKESHITA KOJI
IPC: F16J15/34
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To certainly hold a seal clearance between a rotary ring and a static ring along an overall area from an inner periphery to an outer periphery and prevent occurrence of metallic contact by forming a large number of groove parts along the circumferential direction in the neighborhood of an outlet on the low pressure region side of the seal clearance and land parts between each of the groove parts. SOLUTION: Spiral groove parts are engraved and provided on a side surface facing against a seal clearance 150 of a rotary ring 1 and constitute a dynamic pressure bearing. Inside groove parts are engraved and provided with equal intervals in the circumferential direction on the same side surface of a static ring 2, and these inside groove parts are formed roughly in a T letter shape on a portion to the outlet to the side of a low pressure region B of the seal clearance 150 (that is, a portion to the inner periphery), and they constitute a static pressure bearing with the land parts between each of these groove parts. These dynamic pressure bearing and the inside groove parts and floating force by the static pressure bearing by the land parts show a characteristic to increase (decrease) the floating force when the seal clearance 150 decreases (increases). Consequently, under a condition where a pressure ratio of a high pressure region A and a low pressure region B is high, the seal clearance 150 can be held constant along the overall region of the inner and outer peripheries.
