Title: Speed change controller of vehicular automatic transmission
Inventor: KATAYAMA NOBUYUKI
IPC: F16H61/08
Filed: 1993-08-26
Abstract: PURPOSE:To prevent any interlock to be generated when a second frictional engaging element is engaged, so as to make a shift feeling good by changing the engagement starting time when the engaging operation of the second frictional engagement element is started according to the elapsed time after providing a speed changing means and detecting the speed change command by means of a speed change command detecting means. CONSTITUTION:In a vehicular automatic transmission, when the traveling state of a vehicle is the 3-4 upshift in high speed more than the specific speed, if engagement of a rear clutch 28 and a front clutch 24 is to be released, centrifugal oil pressure remains in respective pistons of the rear clutch 28 and the front clutch 24, thereby the engagement releasing of the rear clutch 28 and the front clutch 24, perpendicularly, the rear clutch 28, is delayed. Thereby, the engagement starting time of a kick down brake 30 is delayed from the 3-4 speed change command time by the specific time T, so as to prevent brake feeling by interlock from being generated in engaging of the kick down brake 30, and also so as to make a shift feeling good.

Title: Paper feeding device
Inventor: ISHII HIROSHI
IPC: B65H1/26
Filed: 1991-08-23
Abstract: PURPOSE:To provide a paper feeding device which can prevent bad effects of dismounting a paper feeding cassette during operation. CONSTITUTION:While paper is being fed, rotation of a motor is transmitted to a paper feeding part 2 by means of a rotary body 12. At this time, an engaging body 14 is energized in the direction opposite to the energizing direction of an energizing member 17 by the turning force of the rotary body 12, and the engaging body 14 is engaged to an engaging part 10 of a paper feeding cassette 9. Thus, occurrence of a jam is prevented by forbidding the dismounting of the paper feeding cassette 9 during paper feeding operation. In addition, too strong force does not act on a rotary paper feeding part 2 during paper feeding operation from the papers existing in the paper feeding cassette 9. So, breakage of the paper feeding part 2 can be prevented beforehand. Furthermore, when the rotary body 12 is stationary and the paper is not being fed, the mounting and dismounting operation of the paper feeding cassette 9 on a main body is allowed by withdrawing the engaging body 14 from the engaging part 10 by the energizing force of the energizing member 17.

Title: Manufacture of rotor for electromagnetic clutch
Inventor: KOBAYASHI KAME
IPC: F16D27/112
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a rotor for an electromagnetic clutch to sufficiently increase the thickness or the height of at least an inner wall by a comparatively small press machine. SOLUTION: This manufacturing method is to manufacture a rotor 3 for an electromagnetic clutch, having an annular bottom wall 10 and at least a cylindrical inner wall 8, through press working wherein a disc-form metallic material forms a material. Therefore, this manufacturing method comprises a throttle process wherein a disc-form material is molded in a cup-form state to form a rise part; a diameter reduction process wherein the rise part is throttled from the outer peripheral side and a material contained therein is moved to a central part; and a burring process wherein the diameter reduction rise part is shaped into a cylindrical inner wall 8.  Since the material is collected to a central part through the diameter reduction process, there is no shortage in a material even at a central part, the thickness and the height of the inner wall 8 are sufficiently ensured, and since the increase of a magnetic flux amount is practicable, a high magnetic suction force is generated. Further, since there is no need for a large and powerful press machine, a processing cost is decreased.

Title: Digital signal processing device, error detecting method and recording medium reproducing device
Inventor: NISHITANI TAKUJI
IPC: G11B20/10
Filed: 1994-09-06
Abstract: PURPOSE: To obtain a reproducing signal processing circuit and a magnetic recording and reproducing device using it enabling a high density magnetic recording by attaining the reducing of a decoding error. CONSTITUTION: The ideal waveform of a reproduced signal is generated by using a decoding result by a PRML channel in an estimation waveform generating circuit 32. The deviated waveform between the waveform and an actual reproducing signal is obtained by a subtractor 31. There is a high probability that error bits are generated at the interval of two bits or four bits due to the characteristics of a GCR code and a maximum likelihood decoding and states of errors of bits are that the bit of one side is added by one with respect to right bits and the bit signal of the other side is subtracted by one. Thus, the correction of error bits are performed in an error correcting circuit 43 by recognizing the pattern of the deviated waveform of errors in an error detecting circuit 41 and detecting the bit intervals of error in an error discriminating circuit 42.
