IPC: G01F1/7084
Filed: 1993-11-10
Abstract: PURPOSE: To lessen the defects of a conventional technique and measure the volume flow rate even if the temperature, pressure, and composition of a gas change. CONSTITUTION: An aerodynamic wrapped body 12 is placed in the flow of a fluid. The wrapped body 1 has an aperture 14 to fill it with a flowing fluid and a thermal pulse generator 16 is attached to the wall of the wrapped body being kept flush with the wall and the generator emits modulated heat pulses simultaneously to the outside and inside of the wrapped body. A first heat sensor 42 is set in the flow and a second heat sensor 44 is installed in the wrapped body. These sensors detect the transmission time or the phase difference of the thermal waves in the flowing fluid and a fluid which does not flow and deduce the flow rate values of the fluid and at the same time compensate all kinds of alteration such as the temperature, pressure, and composition of the fluid. This invented flow mater can be applied for metering a gas.

Title: Bipolar transistor
Inventor: TAKASAKI KANETAKE
IPC: H01L21/331
Filed: 1987-11-09
Abstract: PURPOSE:To increase a collector current and to increase an hFE value by a method wherein a thin layer composed of a substance whose forbidden band width is narrower than SiO2 and wider than Si is laid between an emitter and a base. CONSTITUTION:A film 17 whose band gap is smaller than SiO2 like a silicon nitride film is formed under a poly-Si emitter 13. silicon nitride is a stoichiometric composition like Si3N4 and is not doped with an impurity. In addition, a barrier exists in both a conduction band and a valence band in this device. However, its height is lower than a barrier due to SiO2 in both the conduction band and the valence band. Accordingly, it is possible to increase a collector current. If attention is paid to the barrier of the conduction band, its height is about 3.5eV in the case of SiO2 while the height ot Si3N4 is about 2.0eV; a tunneling probability of an electron is increased sharply. At the same time, the barrier of the valence band is lowered and a tunneling probability of a hole is increased; however, an increase in the tunneling probability of the electron is more effective, and an hFe value of the device is increased.

Title: Decoding method
Inventor: ONO FUMITAKA
IPC: H04N19/91
Filed: 1995-10-31
Abstract: PURPOSE: To realize efficient decoding by controlling the range of a dominated symbol to be within the range of a dominating symbol. CONSTITUTION: An adder 1 adds the value of S to be inputted to the output of an offset arithmetic part 3 just before the adder 1 to calculate the high-order address of the dominated symbol (LPS). Then a comparator 2 compares this value with 0.5 and when it is not more than 0.5 and a generation symbol is the dominating symbol (MPS), the processing by the offset arithmetic part 3 stops with the addition of S. When the value is judged not more than 0.5 similarly by the comparator 2 and the generation symbol is LPS, a base arithmetic unit 4 executes base arithmetic and outputs a base coordinate as a code. On the other hand, a shift digit arithmetic part 5 obtains a multiple (2<n> -fold) necessary for normalization (making a valid range 0.5 to 1.0) from the value of S and outputs the value as a shift digit. Thus, the range of the dominated symbol is controlled to be within the range of the dominating symbol.

IPC: G05B21/02
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a plant controller which can stabilize the control and shorten establishment time. SOLUTION: A ΔMV detection part 1 detects variation ΔMVn-1 in control output value in a precious control period T0n-1 in very sample cycles T1 and an EN detection part 2 detects variation in control deviation from control deviation enn-1 in a previous control period T0n-1 and control deviation enn in a current control period. A ΔMV calculation part 3 calculates current control output value variation ΔMVn from both the outputs of the ΔMV detection part 1 and EN detection part 2 and an MV limitation part 4 uses it to limit an inputted PID control arithmetic output value MVn. Consequently, the value of the output MV of the MV limitation part 4 can be limited, and consequently the control period T0 can automatically be corrected, thereby stabilizing the control and shortening the establishment time.

Title: Dc power supply
Inventor: SEKINO YOSHIHIRO
IPC: H02M3/335
Filed: 1990-10-22
Abstract: PURPOSE:To suppress peak voltage to be applied on a semiconductor element by switching a semiconductor switch OFF when the current flowing thereto is zero thereby suppressing overcharge of a resonance capacitor. CONSTITUTION:When an ON signal q2 is applied on a transistor Q2, DC resonance currents i2 and idc flow and a resonance capacitor Cac begins to discharge from a voltage level Edc. The currents i2 and idc have identical magnitude. When the voltage (v) of the resonance capacitor Cac drops to zero, the current i2 goes to zero. The current idc flowing through a resonance reactor Ldc circulates through a rectifying circuit D and goes subsequently to zero. The ON signal q2 is then interrupted and the transistor Q2 is turned OFF. At that time, switching is made without accompanying any loss. Voltage Cdc of a smoothing capacitor Cdc, i.e., the output voltage, is controlled by varying the ON/OFF interval of the transistors Q1, Q2, i.e., the duration when the smoothing capacitor Cdc charging current idc is zero.

Title: Unit fitting position confirmation system
Inventor: MATSUTANI MITSUHIRO
IPC: H01R13/64
Filed: 1990-10-22
Abstract: PURPOSE:To eliminate the generation of an erroneous output on coincidence or non-coincidence by providing a unit-fitting confirmation means which causes the performance of a slot-number coincidence detection operation only when the unit is in a condition of being fitted on the device side via a corresponding slot. CONSTITUTION:In forming circuits 3a to 3e, a specified terminal of a connector fitted to a unit 7 is grounded to produce a binary code slot number corresponding to each slot. When the unit 7 has been fitted into the slot 2a to 2e, the slot number read out by a read-out circuit 4 is supplied to a slot-number coincidence decision circuit 5. The memory circuit 6 stored in advance with the slot number of the slot into which the corresponding unit is to be inserted supplies its slot number to the slot-number coincidence decision circuit 5. And a unit- fitting confirmation circuit 8 supplies to the decision circuit 5 a fitted condition signal representing whether or not the unit 7 has been completely fitted. This eliminates the production of any error on the coincidence detection which is attributable to an erroneous reading of the slot number issued when the fitted condition of the unit 7 is incomplete.
