Title: Throttle opening control system for internal combustion engine
Inventor: ISHIDA KATSUMI
IPC: F02D9/02
Filed: 1991-09-17
Abstract: PURPOSE:To perform a precise throttle-valve opening control by eliminating the occurrence of any erroneous detection at a reference control position due to damping in one-step response of the stepping motor. CONSTITUTION:A throttle valve 5 disposed in a suction passage 3 is opened and closed by operation of a stepping motor 7. A specified opening position of the valve 5 is detected by a specified-opening detection means 9. With the control position of the motor 7 at a throttle valve opening detected by the detection means 9 being used as a reference control position, the throttle valve 5 opening is controlled by the motor 7. Each time the motor 7 is newly energized on a step-by-step basis, the output value of the detection means 9 is read as an input with a timing immediately preceding to that for hew energization, whereby the positional detection of the valve 5 is performed with a timing in which the damping in one-step response is converged.

Title: Power unit mounting device
Inventor: TAKEHARA SHIN
IPC: B60K5/12
Filed: 1986-11-10
Abstract: PURPOSE:To enable suppression of vibration transmission rate in resonant frequency region, by resiliently supporting a mass member on first and second resilient members and converting the vibration into nonlinear vibration. CONSTITUTION:As the vibration increases, the underface of an upper side flange section 7a of a mass member 7 contacts with a second stopper member 14 while the upper face of an underside flange section 7b contacts with a first stopper member 13. Because of contact with said upper and lower stopper members 13, 14, the mass member 7 vibrates as if it is supported by not only the resilient members 8, 9 for supporting the mass member but also the resilient members 11, 12 for supporting a stopper fixing board. Since the resonant frequency is different from an original frequency when it is vibrated only by the resilient members 8, 9, and nonlinear vibration is produced, vibration being transmitted to the body B side cam be suppressed.

Title: Method for blanking metal plate
Inventor: KITANO MASATOSHI
IPC: B21D28/02
Filed: 1992-10-06
Abstract: PURPOSE:To reduce a vibration and a noise generating at the time of blanking by blanking a work while dividing a blanking process into plural processes. CONSTITUTION:In a metal plate blanking method blanking a plate like work 3 between a punch 1 moving up and down and a fixed die 2, at first, the work 3 is semi blanked by leaving only (t) in the thickness direction on the 1st process, next the remainder part (t) is blanked in the 2nd and succeeding processes. Since a load at the time of blanking and a break through load can be made small, the vibration and the noise generated at the time of blanking can be greatly reduced.

Title: Steam turbine control device
Inventor: HIRATA DAISAKU
IPC: F01D17/24
Filed: 1985-11-29
Abstract: PURPOSE:To prevent the initial load of a steam turbine from being changed with temperatures of a steam governing valve upon joining a generator into a system, by proportionally calculating a change in rotational speed setting before and after joining of the generator with the inverse number of a constant adjusting rate, and adding the result as calculated above to an output setting unit. CONSTITUTION:Before joining a generator 3 into a system, a change in effective opening degree of a steam governing valve 2 with a metal temperature is corrected by a rotational speed setting unit 9. A difference between a rotational speed setting unit 11 after joining of the generator 3 and the rotational speed setting unit 9 before joining of the generator 3 is calculated by a subtractor 15. An output from the subtractor 15 is fed to a calculator 16 to proportionally calculate the output with the inverse number of a constant adjusting rate of a proportional calculator 13, thus obtaining an A-signal. An output from a selector 17 is selected from zero to the A-signal for a fixed period of time by a timer 18 receiving a joining signal. The A-signal is added to an output setting unit 8 to correct a change in rotational speed control output due to the difference between the rotational speed setting units 11 and 9, thus obtaining a C-signal. The C-signal is added to a B-signal generated from the proportional calculator 13 by an adder 14, thus obtaining a control signal for the steam governing valve 2.

Abstract: PURPOSE:To obtain a heat insulating method used for a high temperature annealing furnace by so using in combination carbonaceous heat insulator and alumina/silica heat insulator that the highest heating temperature of the alumina/silica insulator becomes a specific temperature when both are combined for use. CONSTITUTION:A carbonaceous heat insulator which is used at a high temperature side to be faced with an article to be heated as a heat insulator used for a high temperature furnace, and an alumina/silica heat insulator used at the outside are combined for use in such a manner that the highest temperature of the alumina/silica insulator to be faced with the carbonaceous insulator is set to 1000 to 1300 deg.C.

Title: Picture processor
Inventor: SUGIYAMA KENJI
IPC: H04N19/176
Filed: 1989-10-16
Abstract: PURPOSE:To avoid unnatural movement of a picture by recording a signal without revising the system while keeping its field frequency at the recording and applying the system conversion at the reproduction to reproduce a signal of any medium. CONSTITUTION:An input picture signal is fed to a coder 7, where the signal is coded by using the highly efficient movement compensation inter-frame predic tion coding. A data recording device 8 records an input signal onto a medium 4. A data reproducing device 9 reproduces the medium 4 to extract a recorded data. A decoder 10 applies decoding corresponding to the coding at recording to extract a moving vector information and they are fed to a field number converter 11. The field number converter 11 utilizes moving vector information used for the decoding again to apply movement compensation field number conversion. Since the field is generated by moving a picture through interpola tion in this operation, no unnatural movement is caused.
