Title: Detection circuit for received signal quality
Inventor: ITO YOSHIKUNI
IPC: H04L27/14
Filed: 1993-12-13
Abstract: PURPOSE:To detect the quality of a signal with a simple circuit by showing the received signal quality with the count value of an integral counter. CONSTITUTION:This circuit is composed of an integral counter 12 and a timing synchronizing circuit 13. The integral counter 12 samples an output from a direct conversion IC 11 just by a number N (N is a natural number) of times decided for each symbol length. When the signal at that time is 'Hi', it is counted but when it is 'Lo', nothing is counted. Corresponding to a number H of counted 'Hi', a distance ¦H-(N/2)¦ from a threshold value N/2 can be provided, the quality of the output from the direct conversion IC 11 can be detected, and either 'Hi' or 'Lo' can be decided corresponding to the polarity of [H-(N/2)]. The timing synchronizing circuit 13 outputs a reset signal so that the integration circuit 12 can perform its operation for each symbol. Then, the quality of the signal can be led out of the number counted by the integral counter 12.

IPC: B65D5/44
Filed: 1992-11-26
Abstract: PURPOSE:To use a paper tray as a container of fruits and vegetables which contain moisture. CONSTITUTION:A sheet of blank paper is folded to form a nearly rectangular bottom 1 and side walls 2a and 2b which are raised from the bottom 1. Extending parts 3 of the long side walls 2a are folded and pasted on the outer faces of the adjacent short side walls 2b to form a tray main body, and a water- absorbing sheet 4 endowed with antifungal properties is attached so as to cover the inner surface of the bottom 1. Therefore, as moisture contained in the content is absorbed by the water-absorbing sheet 4, a decrease in the rigidity of the tray main body is prevented. In addition, the buffering effect of the water- absorbing sheet 4 prevents the content from deteriorating and its antifungal properties restrain the growth of microorganism and keep its freshness for a long period of time. The spacing effect of the water-absorbing sheet 4 allows the trays in stack to be easily taken out.

Filed: 1989-12-28
Abstract: PURPOSE:To prevent asymmetry from generating in a magnetization inversion interval when a signal is recorded in a medium magnetized in one direction, and to raise reliability by connecting a damping element to have directivity according to the polarity of the recording signal of a write head to the coil end of the write head. CONSTITUTION:Coil terminals 6, 7 are switched alternately in their conductivity by the recording signal. When the coil terminal 6 is made conductive, a diode 5b is turned into a conductive state, and the diode 4b is turned into a non- conductive state. Accordingly, the damping element 5 is turned into an operating state, and the damping element 4 is turned into a non-operating state. Namely, the damping elements 4, 5 having directivity whose operating state changes according to the polarity of the recording signal. Here, when the values of the resisters 4a, 5a are set to be different values, a regenerative signal having the peak of the equal interval corresponding to the magnetization inverting position is obtained at a read head or a write/read head. Thus, the asymmetry can be prevented from generating at the magnetization inversion interval, and the reliability can be raised.

Abstract: PROBLEM TO BE SOLVED: To stably set a cross section of an orifice passage with a target size by forming a deformation absorbing groove opened and extended on an outer peripheral surface along a recessed groove in a state that the pocket-shaped recessed parts are not connected to one another under a condition that it is covered by at least an outer cylindrical member. SOLUTION: A pair of deformation absorbing grooves 50, 50 are formed on a rubber 44 for forming an orifice on both sides through a recessed groove 46 in the width direction of a circumferential groove 42. These deformation absorbing grooves 50 are respectively extended in the circumferential direction along the recessed groove 46 in a state that a positon separated from the recessed groove 46 by a specific distance in the width direction of the circumferential groove 42, keeps an approximately constant interval with respect to the recessed groove 46. The lengths in the circumfernetial direction of the deformation absorbing groove 50 are lengths slightly short to a window part 34.  By applying this structure, the expanded deformation in the direction along an outer cylindrical fitting 14 is generated with priority to a wall surface of the deformation absorbing groove 50, and the swelling deformation amount of the wall surface of the recessed groove 46 is reduced for the expanded deformation. Accordingly the cross section of the orifice passage 72 can be effectively and stably ensured.
