IPC: G11B7/09
Filed: 1984-08-14
Abstract: PURPOSE:To improve high-frequency characteristics by extracting slope information comporising a low-frequency component separated in terms of frequency from a tracking error signal and a jitter correction signal from a disc with a simple means and applying automatic control to the optical system so that the optical axis of a condenser lens is made vertical to the signal face of the disc depending thereupon. CONSTITUTION:When a recording medium (disc 6) is tilted by an angle theta, a shaking fulcrum Q of an optical system P existing at a distance L from the signal face of the recording medium 6 is shaken by Xa=Ltantheta to make the optical axis of the incident light to the recording medium 6 vertical to the signal face of the recording medium 6 based on the slope information detected by a proper means.

Title: Front and rear wheel differential controller of four-wheel drive vehicle
Inventor: NISHIKAWA SEIICHI
IPC: B60K17/348
Filed: 1988-07-08
Abstract: PURPOSE:To prevent trouble occurrence due to a difference between effective radiuses of front and rear wheels by restraining the differential operation executed during drive at the specified speed or higher until it is determined by a decision means that the differential restraint during the high speed drive is permissible. CONSTITUTION:A front and rear wheel differential controller 80 permits or restrains the differential operation of the front and rear wheel differential gear 30 via a differential control clutch 70 according to the vehicle driving state detected by an input system 90 including various sensors. Until a decision means determines that the differential restraint during the high speed drive is permissible, the differential restraint is inhibited when the speed detected by front and rear wheel revolution speed sensors 93 and 94 is over the specified value, at which the differential operation caused by the difference between the effective radiuses of the front and rear wheels is not able to be neglected. Meanwhile, when the drive speed is under the specified value, the differential restraint control is executed any time according to the specified program. Thus the trouble caused by the difference between the effective radiuses of the front and the rear wheels may be prevented effectively.

Title: Paper money discrimination device
Inventor: TAYA KEIICHIRO
IPC: G07D7/00
Filed: 1990-06-28
Abstract: PURPOSE:To improve the discrimination function with minimum sensor number by sensing the carrier of the object to be discriminated in the introduction direction in the process of trap sensing the data of the object to be discriminated with the sensor. CONSTITUTION:Accompanied by the progress of a paper money BL, the output read out by respective sensors transmits the output compared with comparative voltage RH/RH' to a microcomputer UPC. This output calculates the deviation value with the reference value, and estimates the output value at the time of the next process. In the second process, a carrier motor M is reversed, and comparative voltage RM/RM' is selected. Therefore, the paper money BL is reversed and the difference output with the RM/RM', that is, the output whose density is one step higher than that of the first process is generated. Thus, high-discrimination function can be drawn out with the minimum number of sensor arrangement.

Filed: 1989-07-05
Abstract: PURPOSE:To enhance smooth rotation even at a large pre-load and facilitate processing by providing a difference in level having a recessed quantity between the inner end surface of the cap of a rolling body inserting hole and an orbit surface and deforming the difference in level in such a manner that it is asymptotically formed within a proper range in the front and back of the inserting hole. CONSTITUTION:The rotating body inserting hole of a cylinder roll 3 is formed in a radial part of an inner wheel 1, and a cap 4 fixed to the inner wheel 1 is fitted to the inserting hole by a fixing pin 5. The orbit channel 1a of the inner wheel 1 is deformed within a range of an arc L in the front and back of the cap 4, and slightly recessed more than other orbit surfaces. Hence, as the orbit surface is gently recessed, rotating resistance is small, and no catching is caused, resulting in an extended life. To slightly recess a part of the orbit channel, for example, a cylindrical jig slightly protruded over other parts within a certain angle range is press-fitted to a hollow cylinder work corresponding to the inner wheel 1, whereby a part of the work is protruded, and under this state, finish work is conducted. When the work is returned to free state after the processing, a part of the outer diameter surface is recessed.
