Title: Machine for and method of manufacturing curved sheet glass
Inventor: BERUNAARU RUTAN
IPC: C03B23/033
Filed: 1990-08-14
Abstract: PURPOSE: To perform application to the production of an automobile glass plate to which cambering and hardening are executed by providing a roller with mutually inclined two end parts and a curved center part for connecting the end parts.  
     CONSTITUTION: In the case that a glass sheet is curved in more than three groups of a molding roller, the control is arbitrarily applied to the eight groups of the molding roller. When the passing of the glass plate through a passage relating to a molding group is ended, a first curvature radius is immediately taken again, molding is performed from a preceding glass plate with the interval of the almost same length as the length of the molding group generally and then, preparation for receiving a succeeding glass plate is performed. The glass plate obtained in such a manner is provided with a cylindrical front edge 60 matched with the front edge of the glass plate chambered to a cylindrical shape indicated by a single generating line and a rear edge provided with extremely large deflection or deformation.

Title: High pressure fuel pump
Inventor: YAMAZAKI DAICHI
IPC: F04B9/04
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To preferably reduce an operating noise related to closing of a spill valve even when an internal combustion engine is in the low load operation state such as idling operation state. SOLUTION: The cam profile of a cam 25 for driving a high pressure fuel pump is asymmetric between an intake stroke and an injection stroke. To be concrete, the cam angle θ1 in the injection stroke is made larger than the cam angle θ2, so that even if the driving shaft is rotated at a constant speed, the time required for the injection stroke becomes longer, so the volume change speed of the pressure chamber in the injection stroke is lessened.

Title: X-ray ct apparatus of s-r system
Inventor: MIYAZAKI YASUSHI
IPC: A61B6/03
Filed: 1988-08-31
Abstract: PURPOSE:To enhance the quality of a tomographic image and to increase the operation speed in the reconstitution of the image by correcting the so called non-uniformity of (u), wherein an interval in a u-direction becomes small as the distance from an X-ray source and the center of rotation of a detector becomes long, by the use of a deformed two-dimensional coordinates system. CONSTITUTION:A normal line is drawn from the center O of rotation in the direction of beam (l) so as to be right-angled to an X-ray source S and the center of rotation and the length of the straight line OB connecting the center O and the beam (l) is set to (u). An interval in a u-direction becomes gradually small as separating from the X-ray source S and the center O of rotation of a detector. The correction of a CT value is performed with respect to the non-uniformity of (u) by filter processing and, by inverse projection applied on and after, a function for emphasizing the frequeny almost proportional to spatial frequency is used as a filter function for correcting blurr. Next, a reconstituted image f(x, y) subjected to inverse projection operation receives the modulation proportional to a reverse sine of t/D because of the non-uniformity of a coordinates axis (u) to be magnified toward the peripheral part thereof. Then, the correction thereto is added.

Title: Chrominance signal processing circuit for magnetic recording and reproducing device
Inventor: KOTSUBO KAORU
IPC: H04N9/84
Filed: 1987-08-28
Abstract: PURPOSE:To reproduce a chrominance signal with fidelity at all times by providing a detection sensitivity control means to switch the detection sensitivity of a burst phase correction means based on an output pulse of a pulse signal generating means and switching the detection sensitivity of the detection means based on a pulse signal synchronously with the field period of a reproduced video signal. CONSTITUTION:An ID circuit extracts only a burst signal being an output of a band pass filter 4, compares the phase with that of the output being the result of phase- shifting the output of the reference crystal oscillator 14 by 90 deg. to output an ID pulse. The ID pulse is fed back to a PS processing circuit 9 and processed so as to match the phase of the reproduced color signal. In case of the standard mode reproduction, the detection sensitivity of the ID circuit is decided by a capacitor C4 only. In case of the long time mode reproduction, a transistor T2 is turned off for a prescribed time only and only the C4 decides the detection sensitivity of the ID circuit. In other cases, the T2 is turned on to make the C3 effective and the C3+C4 decreases the detection sensitivity of the ID circuit. Thus, defect such as loss of color is improved and the color signal is reproduced with fidelity at all times.

Title: Deadlock detecting system
Inventor: TAKE RIICHIRO
IPC: G06F12/00
Filed: 1985-09-28
Abstract: PURPOSE:To eliminate the misdetection of deadlocks, by judging it as a true deadlock when the time zone from a queuing relation generating time to a reporting time held by queuing relation information is certainly overlaped about each transaction. CONSTITUTION:When the queuing relation is produced between transactions T1 and T2 at a site 1, the state waiting for lock release is reported to a deadlock detecting mechanism 5, but the time when the waiting state is produced and reproting time to the deadlock detecting mechanism 5 are included in the report. The mechanism 5 checks the report together with queuing relation information from other sites 2 and 3 and whether or not the time from the queuing relation generating time to the reporting time overlaps about each transaction by taking the error of a clock into consideration. When the time overlaps, the mechanism 5 decides that the deadlock is not a ghost deadlock, but a true deadlock.

Abstract: PURPOSE:To increase hardness of quenching hardened layer in tooth bottom and tooth face and to increase depth of the layer by shakingly rotating a gear at slower rotating velocity than that at the time of heating while injecting quenching liquid to outer circumferential part of the gear after heating. CONSTITUTION:A high frequency heating coil 50 is used and an outer circumferential part of gear 10 forming the teeth parts is heated while rotating the gear 10. Successively, a quenching liquid 30 is injected to this outer circumferential part of the gear 10 from nozzle holes 61. The above gear 10 is shakingly rotated in both normal and reverse directions at a lower velocity than the rotating velocity at the time of heating while injecting the liquid 30 to this and also shifted up and down in the axial direction. Thus, the hardness of quenching- hardened layer 14 in the tooth bottom 12 and the tooth face 13 is enhanced and the depth D of this layer 14 is increased.
