Title: Filter device
Inventor: SOFUE EIJI
IPC: H03H11/12
Filed: 1993-12-22
Abstract: PURPOSE:To easily select a circuit time constant and to increase the freedom in design by turning the output of a subtraction circuit to zero when the output of a secondary active filter is attenuated and obtaining steep cut-off characteristics. CONSTITUTION:When sine wave signals SW for which 6V is a reference are inputted to a logarithmic transformation circuit 1, output signals 1a become resultant signals for which a negative logarithm signal part corresponds to the positive part of the signals SW and a positive raising signal part saturated at 12V corresponds to a negative part respectively. When the frequency of the signals 1a is present in the pass band of a secondary filter circuit 2, the signals 1a are only inverted and not attenuated with the flat characteristics of a Butterworth filter and the output signals 2a of the circuit 2 are obtained. Also, when the frequency of the signals 1a exceeds the cut-off frequency of the circuit 2, the signals 2a are attenuated and become lower than a reference voltage 6V, the output signals 3a of the subtraction circuit 3 become a zero level and complete signal cut-off is performed.

Title: Method for deciding correction amount of printing photograph
Inventor: KAMIMURA TETSUSHI
IPC: G03B27/73
Filed: 1991-10-31
Abstract: PURPOSE:To prevent the dispersion of quality by collating a film which is enlarged and printed with a variable density scale and finding out the scale having the same variable density. CONSTITUTION:The film which is enlarged and printed by an enlarger-printer 22 is compared and collated with the monochrome or color variable density scale on a digitizer, and the scale of the same density is found out and specified on the digitizer, so that the correction amount of a filter and exposure corresponding to the scale are obtained. In the case that color correction must be still added to a printed image which is test-printed, the printed image obtained by test printing is compared and collated with the color map and a positive image expressing equal color tone is found out on the scale and the position thereof is specified by the digitizer, thereby obtaining the correction amount of the filter and the exposure corresponding to it. Thus, since individual difference is comparatively restrained and the correction amount of the filter and the exposure in the case of enlarging and exposing are correctly decided, the dispersion of the quality is prevented.

Title: Automatic transmission shift control device
Inventor: MORITA SUSUMU
IPC: B60W10/10
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce the shift time as much as possible and thereby improve responsiveness by maintaining constant engine torque during shifting and controlling the joint pressure to an appropriate value without detecting an input rotation speed of the transmission. SOLUTION: When it is determined that a command for starting shift has been given (S1), the opening of the throttle valve is set corresponding to the target torque during shifting (S2). Specifically, the table of the throttle valve opening is retrieved from the target torque and the engine speed. Simply, the throttle valve opening is set from only the target torque. In this way, the opening of the throttle valve is controlled to the set opening (S3). Then, whether the end shift command has been given is determined based on the shift information (S4) If the end shift command has not yet been given, the engine torque control during shifting continues (S3), and when the end shift command has been given, the routine ends and it changes back to the normal open valve control.

Filed: 1992-12-28
Abstract: PURPOSE:To attain the sure and stable fixing of a disk over a long period by adding further the pressing without the inclination of the disk at the time of loading. CONSTITUTION:An optical disk 12 is loaded from the outside and placed on the end surface of the recessed part 14a of a rotary table 14. After that, a clamper 10 is moved downward by a pressing mechanism almost as much as the end surface is brought into contact with an outer peripheral member of the optical disk 12, then stopped. Also, after the clamper 10 is stopped, the pressing is continued by a movable pressing top 18 in such a manner that a chevron part 18a of the movable pressing top 18 abuts on the peripheral member of a mounting hole at the center part of the optical disk 12 by the pressing force of a coil spring 16, then the optical disk 12 is positioned at the center axis position of the rotary table 14. Since the disk 12 is never arranged in the inclined state on the rotary table 14 at this time, the inclination of the disk 12 is not generated when the disk 12 is pressed and fixed subsequently by the movable pressing top 18.
