Title: Ignition timing control device in idling
Inventor: NAKATANI KATSUMI
IPC: F02D29/00
Filed: 1991-10-29
Abstract: PURPOSE:To correct waving of the engine rotation frequency evenly by calculating a correcting amount asymmetrical at the advance side and the lag side of the ignition timing according to the deflection of the calculated engine rotation frequency, in the engine operating condition set at the nonlinear part near the torque peak. CONSTITUTION:The idle condition of an internal combustion engine 10 is detected in a detecting means 11, while the engine rotation frequency is detected in a rotation frequency detecting means 12. In a correcting amount calculating means, a correcting amount asymmetrical at the spark advance side and at the spark lag side of the ignition timing is calculated according to the deflection of the engine rotation frequency calculated by the second calculating means 14, at the engine operating condition in which the standard ignition timing calculated by the first calculating means 13 is set at a nonlinear part near the torque peak of the ignition timing torque property. Furthermore, in an ignition timing operation means 16, based on a correcting amount, a value to correct the standard ignition timing and to determine the ignition timing is output. Consequently, waviness of the engine rotation frequency can be corrected evenly.

Title: Pattern formation of photoresist
Inventor: YOSHIDA MASAYUKI
IPC: H01L21/30
Filed: 1987-11-11
Abstract: PURPOSE:To reduce a wiring pitch by controlling an exposure amount so that a photoresist is photosensed in the total exposure amount of a directly radiated light and a reflected light by a metal film. CONSTITUTION:A wiring path 2 is formed on the upper face of a semiconductor substrate 1, an insulating film 3 is further laminated, and the film 3 is coated with a photoresist 4. A photomask 5 is placed above, and an ultraviolet light 6 is irradiated. If an exposure amount is 80mJ/cm<2> or less, the photoresist does not substantially photosense, while if it exceeds 80mJ/cm<2>, it starts photosensing. When the exposure amount is set to 80mJ/cm<2> and the reflecting efficiency of the path 2 is 50% or less, the exposure amount of the photoresist 4 in which the path 2 is presented directly thereunder becomes 120mJ/cm<2>, and it is photosensed, but the photoresist 4 in which the path is not presented, is not photosensed. Accordingly, when it is developed, a connecting hole 7 is formed only at the insulating film in which the path 2 is presented. A wiring path 8 is connected to the path 2 through the hole. Thus, a wiring pitch can be reduced.

Abstract: PURPOSE:To measure cathechol amine with a higher reproducibility by controlling a switching timing between a passage switching valve having a pretreating column mounted thereon and a passage switching valve for switching between solvent for cleaning and a buffer liquid for desorption. CONSTITUTION:When a sample injector 5 is turned ON at a time point 0 of a time A, a measuring reagent containing cathechol amine is conveyed on a buffer liquid 1 for adsorption to be injected into a pretreating column 7 through a changeover valve 6. The desorption of the cathechol amine adsorbed onto the column 7 is performed by turning ON the valve 6 at a time point 2 of the time A on switching to supply the buffer liquid 3 for desorption. In this manner, the cathechol amine injected into a separation column 10 is separated to be detected with an electrochemical detector 11. A data processor 13 starts at a time point 2 and stops at a time point 12. The valve 9 is turned ON at the time point 12 and switched to supply a solvent 8 for cleaning. This enables measurement with a higher reproducibility.

Title: Optical disk reproducing method and optical disk device
Inventor: OISHI YASUO
IPC: G11B7/20
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To enable high-speed and efficient data transfer by providing a means for switching algorithm of head transfer in accordance with a required file size. SOLUTION: A suitable sequence is selected from a few kinds of optical head transfer sequence prepared in accordance with a required file size, against data read request from the host computer 14. For example, when the required file size is 5, a first optical pickup 3 moves to the data position with reading required, reading data twice as much as the read unit data. In this case, a second optical pickup 25 moves to the position backward by the read data size of the optical pickup 3, starting to read data three times as much as the read unit data. Thus, if the data of the file size 5 is read out, it turns to 3.25 cycle, completing the reading earlier by one cycle compared with 4.25 cycle.
