Title: Clock timing controller
Inventor: NAKAGAWA NAOKO
IPC: G06F1/08
Filed: 1990-08-10
Abstract: PURPOSE:To realize an operation in a low frequency and the reduction of power consumption by providing a clock timing controller which can generate a period which is almost the same as the data holding period of a high speed operation with the low frequency operation. CONSTITUTION:This controller has a clock timing controller A corresponding at regular operation time which corresponds to the high speed operation and a clock timing controller B for low frequency operation which corresponds to the low frequency operation and it has a switch which changes over the two controllers A and B by the high speed operation and the low frequency operation. The clock timing controller B corresponding to the low frequency operation can realize the holding period, namely, the period when an output C is '0' in the same way as the period when the high speed operation is '0' in the state of the low frequency. Then, the change-over switch selects the controller B and the clock timing is controlled by the controller B. Thus, the occurrence of an accident that the holding of data is lacked is prevented and power consumption can be reduced.

Title: Sliding roof construction for vehicle
Inventor: NIWA TOSHIAKI
IPC: B60J7/043
Filed: 1984-10-11
Abstract: PURPOSE:To increase the longitudinal length of the opening made in an externally sliding type roof, when the opening and closing lid is opened, by constituting an opening and closing lid guide of two guides which are arranged in parallel with each other. CONSTITUTION:For completely opening an opening and closing lid 2, a tilt-up mechanism 51 is actuated to swing up a driving lever 52 and a frame-side sub guide rail 41 is swung upward about the center of a supporting shaft 43, whereby tilting up the rear part 5 of the opening and closing lid via a rear slide stay 61. A driving cable not illustrated in the drawing is slided rearward to pull the opening and closing lid 2 toward a rear part roof 6 via a front slide stay 41. Such parallel arrangement of a main guide rail 32 and the frame-side sub guide rail 41 prevents the front and rear stays 11 and 61 from relative interference so that said stays may be guided by guide rails 32 and 41, respectively to make forward and rear slide. Thus the stroke of the opening and closing lid 2 is elongated, hence increasing the longitudinal length of the open part of the sun roof.

Abstract: PURPOSE:To enhance the straightness of a cutting line in the width direction in a supporting device to support thin metal plate being transported for manufacture of cans, by preventing a long plate from dangling and dislocation due to pushback by a stopper. CONSTITUTION:A thin metal plate is fed into a cutter 38 in the direction as shown by arrow a, where the two side edges are cut off, and sent off as in the plate transport direction (A). When it is located alongside the bottom of a guide roller 9, a plate attraction magnet 28 applies the attractive force to prevent its central part from dangling. Thus each of the plates fed one after another is attracted by magnets 29, 30, 31, and when its leading edge runs against a butting part 16, a damping stopper 11 damps the effect, and comes in contact with a retraction preventive stopper 17 to stop there upon being pushed back by the repulsive force of a spring 13. At this time, a cylinder 25 is actuated to elevate a supporting member 27 and magnets 28-31 as in a single piece, and if the attractive force of these magnets 28-31 to the plate is released, the plate is received by a guide bar and dropped onto a table 41.
