Title: Manufacture of automobile uniform velocity joint
Inventor: HIBINO YOSHIHIRO
IPC: C21D9/40
Filed: 1987-10-07
Abstract: PURPOSE:To manufacture a uniform velocity joint improved in hardenability at the sliding surface by applying carburizing, hardening, and tempering treatments to an outer race and an inner race, assembling them while attaching a rolling element between them, and then providing rotation under loaded condition so as to form the contact surface into martensite. CONSTITUTION:An outer race and an inner race are subjected to carburizing, hardening, and tempering treatments, by which the amount of precipitation of residual austenite is regulated to 30-55% at a depth as far as 30-50mu from the surface and also to 15% at a depth of >=50mu, respectively. The above outer and inner races are assembled while attaching a rolling element between them, and then, 1,000-5,000 revolutions are provided under a load of 100-150kg/mm<2> surface pressure at the contact surface to give a break-in rotation to the rolling element. Subsequently, 500-2,000 revolutions are provided under a load of 400-450kg/mm<2> surface pressure, by which residual austenite at the contact surface is transformed to martensite by means of working-induced martensite transformation. By this method, the uniform velocity joint in which the contact surface of the rolling element is hardened can be obtained.

Title: Ink jet recording method and apparatus
Inventor: KASHIWAZAKI AKIO
IPC: B41J2/205
Filed: 1992-09-21
Abstract: PURPOSE:To obtain good printing grade, scratch resistance, water resistance, light fastness or the like by applying or jetting a soln. containing a polar polymer to a recording medium before recording is performed simultaneously with recording or after recording is performed. CONSTITUTION:A soln. of a polymer having a polarity opposite to that of the polymer contained in a recording soln. is sprayed on a recording medium before recording is performed and the recording soln. is emitted to the recording medium at the part where the liquid droplets of the polymer soln. is bonded to perform recording. That is, by treating the surface state of paper to bring the same to a constant state, good printed matter not affected by the kind of paper is obtained. As an example of an apparatus, the solution containing the polymer having a polarity opposite to that of the polymer contained in the recording soln. is jetted toward recording paper at first from an auxiliary head 1b and, after the elapse of a definite time, recording ink is jetted from a main head 1a to perform recording. At this time, the impact points of the main head and the auxiliary head are allowed to nearly coincide with each other.

Title: Digital pll circuit
Inventor: NAGAI KENJI
IPC: H03L7/06
Filed: 1986-10-24
Abstract: PURPOSE:To improve S/N by varying a frequency division ratio by a frequency division period equal to the same number of times with the specific frequency of a reference frequency signal when the phase difference between a reference input clock signal and an internal clock signal reaches a phase difference corresponding to the specific number of cycles of the reference frequency signal. CONSTITUTION:A phase comparator PFC holds a phase difference signal uo (a 1st phase difference signal) or do (a 2nd phase difference signal) at a high level when the phase difference between the reference input clock signal phis and internal clock signal phis2 reaches the phase difference corresponding to six cycles. A frequency division ratio control circuit FDC generates a phase control signal up or down according to the phase difference signal uo or do outputted by the phase comparator PFC and varies the frequency division ratio of a variable frequency dividing circuit VFD by six cycles. Therefore, if a temporary phase shift is caused by jitters, etc., the phase can be locked without varying the sampling timing of an oversampling type A/D.D/A converting device abruptly, and the S/N of a communication system is prevented from decreasing.

Title: Image data compressing device
Inventor: WATANABE MIKIO
IPC: H04N1/415
Filed: 1988-10-07
Abstract: PURPOSE:To make a compressed data length to an approximately fixed value and to eliminate the partial deterioration of an image quality by repeating operations by a normalizing means, a coding means, and a counting means while changing a normalizing coefficient so that a data quantity count value for one screen can be within a prescribed range. CONSTITUTION:Original image data for one screen are partitioned into plural blocks, orthogonal transformation is executed for the original image data for every block in an orthogonal transformation part 11, and the data are normalized by further dividing an obtained transformation coefficient by the normalizing coefficient in a normalizing part 13. Compressed data are obtained by coding the normalized data in a coding part 14. Further, the operations by the normalizing part 13, the coding part 14, and a counter 15 are repeated while the normalizing coefficient is changed so that the total data quantity of the compressed data for one screen can be always approximately fixed. Thus, the compressed data length for one screen can be approximately fixed, and the image data can be compressed without partially deteriorating the image quality even when the partial difference in fineness exists in a pattern.
