Title: Internal combustion engine control method and device
Inventor: OTANI GENKI
IPC: F02B31/02
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To inhibit a shock due to torque reduction when an air flow control valve in an internal combustion engine is switched from a closed valve state to an open valve state. SOLUTION: An unburned gas and a burned gas stored in a second intake air port between the air flow control valve and a second intake air valve are supplied to a combustion chamber by opening the air flow control valve (In S310, 'YES'), and a fuel injection amount to the combustion chamber is temporarily reduced (S340 to S360). Thus, an appropriate fuel concentration is obtained in the combustion chamber in response to lack of an oxygen amount. In consequence, the reduction of engine torque is compensated to inhibit the shock.

Title: Clock signal generating circuit
Inventor: KAMATA YOSHIHIKO
IPC: H03K5/00
Filed: 2001-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a clock signal whose frequency is close to a desired frequency from a reference clock signal. SOLUTION: A frequency of a clock signal CLK10 is divided into 1/2, 1/4, 1/8, 1/16, and 1/32 by a frequency-dividing circuit 10 to generate clock signals CLK12, CLK14, CLK16, CLK18, and CLK20. Frequency detecting circuits 12-20 compare the frequencies of the clock signals CLK12-CLK20 with a preliminarily set reference frequency fST, and when the frequencies are higher than the reference frequency fST, set the levels of detection signals C10-C18 so as to be H, and set them so as to be L in the other case. A frequency selecting circuit 22 selects the clock signal having a frequency close to the reference frequency fST from among the clock signals CLK10-CLK20 outputted from the frequency- dividing circuit 10 based on the pattern of the levels of the detection signals C10-C18.

Title: Edge detector by ultrasonic wave
Inventor: NISHIDA FUMIHIKO
IPC: G01S15/06
Filed: 2001-05-09
Abstract: PROBLEM TO BE SOLVED: To easily detect an edge position of a detected body in a short time. SOLUTION: An irradiation beam controller 2 generates a highly directional beam emitted substantially perpendicularly toward the detected body 10 by regulating an excitation phase of an arrray-arranged ultrasonic transmitter 3. When an irradiation position is in an inside of the detected body 10, a reflected wave is received in the substantially same level by ultrasonic receivers 4, 5. When the irradiation position is in the vicinity of the edge in the detected body 10, only the one ultrasonic receiver receives sometimes the reflected wave. When the irradiation position is in an outside of the detected body 10, both ultrasonic receivers 4, 5 do not receive sometimes the reflected wave.  The position of the detected body 10 showing the maximum value is detected based on a result provided by subtraction processing between the reception levels of the two ultrasonic transmitters 4, 5 in a computing unit 8, in an edge position determining part 9. The position is the center position of the edge.

IPC: G01N1/22
Filed: 2001-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a sample retaining apparatus for showing cooling capacity stably and efficiently in spite of its simple structure. SOLUTION: An inner heat capacity body 62 made of a metal has a projection. A surface 62b of the projection is formed round at the center by bending, and a trap pipe 63 is fitted to a groove 67. The projection is inserted into a recess 61a of an outer heat capacity body 61 made of a metal, and the surface 62b and the wall surface of the recess 61 give a pressing force to the trap pipe 63. The press force brings the trap pipe 63 into close contact with the heat capacity body 62 to improve the heat conversion efficiency between them. The groove 67 is designed to be wider than the outer diameter of the trap pipe 63, and a gap is generated at both the sides of the trap pipe 63 fitted to the groove 67.  The gap becomes a refrigerant passage 68 to pass a refrigerant, and the refrigerant and the trap pipe 63 come into planar contact to cool a sample gas in the trap pipe 63 rapidly for liquefaction. After the sample is condensed, a heater 9 is turned on to gasify the sample again.

Patent JP-2002349688-A (JP)
Title: Variable speed control device
Inventor: IDOGAWA MASANAO
IPC: B60W10/10
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To solve insufficiency of fuel consumption improvement caused by switching combustion form from stratified combustion to homogeneous combustion, by shift change or by making the form kept in homogeneous combustion due to no change in shift. SOLUTION: When predicting a switch of combustion form from stratified combustion to homogeneous combustion with shift up ('YES' in S160), the shift-up is restricted by setting 'ON' in a shift-up inhibiting flag (S170). If the shift-up were to be permitted, the increased amount of fuel consumption generated by switching combustion form from the stratified combustion to the homogeneous combustion would be more than the reduced amount of fuel consumption by the shift-up itself. Therefore, the shift-up is restricted not to be executed. By so doing, the stratified combustion can be maintained and the improving effect of the fuel consumption by the combustion form is fully achieved.

Title: Liquid crystal display device and its driving method
Inventor: KIM YOUNG-KI
IPC: G02F1/133
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To make data voltage to be charged sufficiently to respective data lines in a liquid crystal display device. SOLUTION: In this display device, switching elements 410 are inserted respectively among adjacent data lines of data lines D1 to Dm to make the data lines D1 to Dm to be short-circuited right before gate-ON voltage is applied to gate lines G1 to Gn. When the adjacent data lines D1 to Dm are made to be short-circuited in this manner, the data lines D1 to Dm can be made to be charged preliminarily to the intermediate level Ve in the range of potential changes by an electric charge sharing effect. Thus, the distortion of the data voltage Vd due to the resistance of the data lines and parasitic capacitances can be improved by making the adjacent data lines D1 to Dm to be short- circuited in this manner.

Filed: 2001-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a battery grid that has a mechanical strength equal to a reciprocating type expanded grid while maintaining the speed of manufacture as a rotary type expanded grid, and its manufacturing method. SOLUTION: In the manufacturing method of this battery grid, a disk cutter which has arranged on the circumference, with an interval, a protruded cutting blades, that develops in mesh shape while forming a slit on a lead alloy sheet, is arranged in step from the side end of the lead alloy sheet along the moving direction of the lead alloy sheet.

For one rotation of the rotating axle of the disc cutter, a mesh having the same number of slits as the protruded cutting blades can be made. And since the disc cutter is made to have a sufficient strength against the sheet strength, even if the thickness of the disk cutter is made thicker, interference with the adjoining disc cutters is prevented as the disc cutter is arranged in a step shape.
