Patent JP-H02305443-A (JP)
Title: Manufacture of semiconductor device
Inventor: MATSUDA JUNICHI
IPC: H01L29/10
Filed: 1989-05-19
Abstract: PURPOSE:To contrive the improvement of the operating speed of a transistor and the improvement of the reliability of the transistor by a method wherein the formation of an impurity region and a concentration distribution in the impurity region are specified. CONSTITUTION:As an N-type layer 4 is formed and a channel region, through which source and drain currents are made to flow, is formed into a low-concentration N-type, the speed of an electron transfer can be increased. As a P-type layer 3 of an impurity concentration higher than that of a P-type Si substrate 1 is formed under the layer 4, the spread of a depletion layer at a time when a voltage is applied between a source and a drain is little and a punch-through voltage can be increased. As a low- concentration N-type layer 10 is formed in the vicinity of the drain, a current path becomes more distant from the interface between the Si substrate and an SiO2 film and even if hot carriers are generated, a probability that the hot carriers are injected in the interface, an SiO2 film 5 or a polycrystalline Si gate electrode 7 is reduced. Therefore, a fluctuation in the denaturation of a transistor is inhibited. As a low- concentration N-type layer 11 is provided on the outside of a high-concentration N-type layer 12, the P-N junction capacitances between the source and drain and the substrate are reduced and the improvement of the switching speed of the transistor is contrived.

Title: Fuel feeding device
Inventor: YASUDA AKIO
IPC: F02M21/02
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To quickly open an injection valve in a fuel feeding device for injecting a gas fuel supplied from a fuel tank through a communication passage into an internal combustion engine through an injection valve by controlling the opening and closing of the injection valve and communication passage so as to reduce the fuel pressure added to the injection valve when the internal combustion engine is stopped. SOLUTION: When an engine stopping operation is performed, it is judged whether the traveling intake air temperature is a prescribed value or lower, and when the traveling intake air temperature is -20 deg.C or lower, a pressure reducing processing is performed so as to smoothen the valve opening operation in starting. At this time, in an ECU 18, a timer is started, a trial valve opening flag is successively set, and the current-carrying to a delivery shut-off valve 16 is stopped to interrupt a delivery pipe 17 from a regulator 14. The fuel pressure in the delivery pipe 17 is gradually reduced by performing the ignition of an ignition plug and the fuel injection by the injector 11. When a prescribed pressure reducing time passed, or when the fuel pressure is reduced to a prescribed value, an engine 10 is stopped.

Title: Stack control method
Inventor: KIMURA YASUNORI
IPC: G06F12/02
Filed: 1983-07-15
Abstract: PURPOSE:To decrease the loss time at the time of the access to the stack, by switching the circuit by the multiplexer when the access is executed to the position shown by the present pointer. CONSTITUTION:The pointer (position information) at the time of the access to the stack 9 selects either the value of the pointer register 4' itself or operation results by the adder 6' with the multiplexer 12. The selection operation of the multiplexer 12 is controlled by the polarity of the signal added to the control signal terminal 13. For example, when the value of the pointer is not changed by reading and writing, the pointer 4' value is selected. After the data is taken out, when the value of the pointer is decreased, after the value of the pointer register 4' is directly obtained by the multiplexer 12 and is accessed to the stack 9', ''-1'' is added to the terminal 7', after the result, the value outputted from the adder 5' is set to the pointer register 4'.

Title: Air valve
Inventor: YAMADA MATSUO
IPC: F16K31/18
Filed: 1978-10-19
Abstract: PURPOSE: To prevent a main valve from being pushed up by air having flowed into a guide cylinder, by immediately discharging the air to the outside through an air passage and a large-quantity suction/discharge port in large-quantity exhaust.  
     CONSTITUTION: When there are no water and pressure in a water duct, air can freely flow into and out of a valve casing 1 through a large-quantity suction/discharge port. Starting the supply of water into the water duct in that state, the air in the duct flows from an inlet port 4 through a gap 3 and the air hole 6 of a guide cylinder 2 and is discharged to the outside through the large-quantity suction/discharge port 10 as shown by arrows in Fig. At that time, negative pressure hardly takes place on the top of a main valve 11 because the central part of the top is conical. Therefore, the main valve 11 is never attracted upward by negative pressure.

Title: Mass flowmeter
Inventor: HASEGAWA HIROAKI
IPC: G01F1/84
Filed: 1990-05-18
Abstract: PURPOSE:To remove the effects of external vibration noises and to improve measuring accuracy and response by fixing only magnetic bodies to a sensor tube, fixing an exciting means which attracts the magnetic bodies to a non- vibrating part which is not associated with the vibrations of the sensor tube, vibrating the tubes, and detecting the displacement. CONSTITUTION:A pair of sensor tubes 2 and 3 are shaker with the phase difference of 180 deg., respectively. Coriolis force is generated at straight tube parts 2a and 2b of the upper tube and straight tube parts 3a and 3b of the lower tube 3. The displacements -delta and +delta of the straight tube parts are detected as the signals of the time difference with pickups 9 and 10 based on the Coriolis force, and the signal is made proportional to a flow rate. At this time, compact, light-weight magnetic bodies 12 are fixed to the tubes 2 and 3 in shakers 13 and 14. The tubes 2 and 3 can be vibrated only by fixing an exciting element 11 to an outflow tube 6. An unnecessary weight is not added to the tubes 2 and 3. Therefore, the flowmeter becomes hard to be affected by the external vibration noises, and high accuracy and high response are obtained.
