Filed: 1990-03-30
Abstract: PURPOSE:To improve the follow-up performance of a head without decreasing the recording capacity of a disk by writing pieces of positioning information on the obverse and reverse surfaces of the disk in deviation relation and reading those pieces of information by a couple of heads. CONSTITUTION:The positioning information on the obverse surface of the magnetic disk is read out by a head 7 and sent to a CPU 27 through a head amplifier 15 and a pulse detector 19. The CPU 27 detects the quantity of a position shift with the positioning information S2 and controls a VCM driving circuit 29, so that the head 7 reads data recorded in a target sector. Simultaneously, a head 11 reads the positioning information recorded on the reverse surface of the disk and sends it to the CPU 27 through a head amplifier 17 and a pulse detector 21, so a side position shift is corrected according to the information. The position shift correction is made twice in one sector. Consequently, the follow-up performance of the heads 7 and 11 is improved without decreasing the recording capacity.

Title: Method for packaging article
Inventor: FUSHIHARA KAZUHISA
IPC: B65B31/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To package an article with a pressure raised inside a packaging material by vaporizing a liquid or solid vaporizable substance after the liquid or solid vaporizable substance which vaporizes at normal temperature with normal pressure is inserted inside the packaging material together with the article and the packaging material is sealed. SOLUTION: Two tennis balls 1 with an internal pressure of 186 kPa for example and dry ice 2 taken out of a cold insulating container are put in a steel can 10 with an upper part opened, and a lid material 3 is put over the upper opening and caulked for hermetically sealing the steel can 10. If this is left under normal temperature with normal pressure, the dry ice 2 vaporizes to allow the inside of the steel can 10 to be kept at a high pressure. This packaging method facilitates operation since a vaporizable substance such as dry ice 2 may be only packaged with an article in a packaging material. In addition, since the vaporizable substance such as the dry ice 2 is relatively inexpensive, packaging can be done at a low cost.

Abstract: PURPOSE: To cut the product to be halved exactly at right angle to the end face, and to prevent the wear and break of the titled dies, by installing the groove for the relief of the excess metal of the blank in the approximate middle of each of a pair of cutting dies.  
     CONSTITUTION: The groove 5 is formed in the cutter dies 3' behind the point at about 1/3 of the dies. The dies 3', 3', bite the products 4', 4', and the cutting work is proceeded; hereupon, the forming force F' is given toward the middle zone by the action of the inner cutting planes 3'a, 3'a, as shown by the arrow mark; however, since the grooves 5, 5, have been formed in the middle zone, the distance (l) between the inner cutting planes 3'a, 3'a, that is the slant faces, is shorter as compared with the conventional method; as a result, the forming force F' is also so small that it does not affect the end face of the product. Furthermore, with the progress of the cutting work, the excess metal is partly pushed into the hrooves 5, 5, so that the cutting work is made easy and the wear and break of the dies 3', 3', are prevented.
