Inventor: MIZUTANI TORU
IPC: H01L21/82
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To reduce the scale of unsatisfactory pattern data. SOLUTION: This method verifies a wiring short-circuit between pads 11 and 12, between nodes of a semiconductor integrated circuit or between the pads 11 and 12 and the nodes. In this case, all the wirings 13 to 16, which are interposed between the pads 11 and 12, between the nodes or between the pads 11 and 12 and the nodes, are sampled, all branch wirings 18 to 25 having not an endpoint jointly with other wirings are removed from among all the wirings 13 to 16 and the wirings subsequent to the removal of all the branch wirings 18 to 25 are outputted as unsatisfactory pattern data. The branch wirings 18 to 25 are removed and the unsatisfactory pattern data is produced. The scale of the unsatisfactory pattern data is significantly reduced, it is very facilitated to specify a short-circuited place and the improvement of a verification efficiency is contrived.

Title: Band expanding and opening device for drum can
Inventor: YOSHIMOTO NOBUTAKA
IPC: G21F9/36
Filed: 1988-11-17
Abstract: PURPOSE:To automatically expand and open a band for tightening up a cover of a drum and to remove it without being caught on the cover by providing radially many axes on the rear face of a supporting plate provided on the upper part of the cover of the drum can. CONSTITUTION:When a supporting plate 10 descends, a cover receiving roller 20 provided on the rear face of the peripheral edge of the supporting plate 10 comes into contact with the outside of a band 50 of the outside periphery of the cover, and also, an engaging claw 23 of an axis 21 is positioned on the inside of the band 50. In this state, when a bolt and a nut of the band 50 are loosened by a nut runner device 40 and a star cam is rotated by a prescribed angle by a cam driving device 26, each axis 21 moves outward radially and simultaneously since its base end is pressed by the cam, and the engaging claw 23 pushes and expands the band 50 outward equally from the inside. As a result, the band 50 becomes a state supported in the cover receiving rollers 20, therefore, when the supporting plate 10 is allowed to ascend as it is by a cylinder, the band 50 is removed automatically from the cover, and in this state, simultaneously, the cover attracted by an electromagnet can be opened automatically from the drum can.

Abstract: PURPOSE:To reduce the size of optical parts by forming at least one layer of spiral thin films which are coated with insulating layers and consist of a superconducting material on the side faces of a magneto-optical crystal and generating a magneto-optical effect by the magnetic field generated when electric current is passed to the thin films. CONSTITUTION:The superconducting layer 202 is formed on the side faces of the yttrium-garnet (YIG) crystal 201. The layer 202 is worked to a spiral shape. The insulating layer 203 consisting of SiO2 and the superconducting layer 204 consisting of the same material as the material of the layer 202 are then successively formed thereon. However, the end part of the insulating layer 203 is partially removed in order to conduct the superconducting layers 202, 204. The superconducting layer 204 is then worked to a spiral shape and finally, the insulating layer 206 is formed. Polarizers 102, 103 are disposed to the YIG crystal 101 formed with the superconducting coils along the optical axis thereof so that light can pass the same only from the left to the right. Since the need for using a permanent magnet is thereby eliminated, the size of the optical parts is reduced.

Filed: 1987-11-19
Abstract: PURPOSE:To enhance the hardness of an oxide film and ensure that flaws in an image area or contamination of a printed matter hardly occurs even where the amount of the oxide film formed is small, by graining at least one side of an aluminum plate, and anodizing the grained surface in a molten salt electrolyte. CONSTITUTION:An aluminum plate is grained, then chemically cleaned, and anodized in a molten salt electrolyte. The electrolyte is a molten salt obtained by melting a salt, which is solid at normal temperature, at a temperature below the melting point of aluminum, 660 deg.C. Specifically, at least one of a sulfate, a nitrate, a perchlorate and the like is incorporated singly or in combination. It is necessary to the anodizing treatment temperature to only be not less than the melting point of the salt, but a temperature of not more than 300 deg.C is preferable in view of the annealing effect of the treatment on aluminum. The current density to be used is preferably 1-40A/dm<2> from the viewpoint of film formation efficiency. The weight of aluminum oxide thus formed is 0.3-5.0g/m<2>, and a photosensitive layer is provided on the base for a planographic plate thus obtained, whereby a photosensitive planographic plate material can be obtained. The plate material is then subjected to a plate making treatment.

Abstract: PURPOSE:To precisely use an article lending limiting function by storing a lending time limit in the title device, recording the lending time limit in a customer card, and erasing data related to an article stored in the device and recorded in the customer card when the lending time limit expires. CONSTITUTION:While the device is equipped with a storing means to store the code of the article to be lent, a user code, and the lending time limit under a corresponding state to each other, the device records the code of the article to be lent and the lending time limit in the customer card which is inserted into the device at lending time. Further, when it is decided that some article having the expired lending time limit exists, the device erases the stored data related to the article having the expired lending time limit stored in the storing means and erases the data related to the article having the expired lending time limit recorded in the customer card when the customer card is inserted into the lending device. Therefore, the recorded state of the number of lending limited articles in the lending device coincides with that in the customer card. Thus, the article lending limiting function can be precisely worked without any irrationality.
