Title: Method for designing reticle pattern
Inventor: NAKASUJI MAMORU
IPC: G03F1/36
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a reticle pattern can be designed to satisfy both the accuracy of a formed pattern and the throughput. SOLUTION: One layer 1 of a semiconductor chip is divided into small regions 2, having small dimensions which are nearly equal to the spreading area of the back-scattered light of a transfer electron beam, and the area of a pattern in each small area 2 is calculated. When the difference between the largest and smallest values among the area ratios exceeds 25%, a reticle pattern is designed so as to perform post-transfer proximate effect correction on a wafer. When the difference is 15-25%, the pattern is designed to perform post-transfer proximate effect correction on the wafer for critical layers or to locally change the pattern dimension of the reticle for noncritical layers. When the difference is less than 15%, no correction is made for non-critical layers, or a correction is made by locally changing the pattern dimension of the reticle for noncritical layers.

Title: Preventive device for defective releasing of air brake for car
Inventor: KURODA YOUICHI
IPC: B60T15/36
Filed: 1980-06-27
Abstract: PURPOSE: To prevent the nonreleasing of the brake by a method wherein a release confirming valve is disposed between a brake pipe and a two pressure type control valve, and an auxiliary air reservoir and an expanding chamber mounted apart from the air reservoir are communicated when taking off the brake.  
     CONSTITUTION: Compressed air is supplied to the brake pipe 5 in order to take off the brake from a brake working condition shown in the figure. When the pressure of the brake pipe 5 exceeds the pressure governing value of a pressure regulating valve 17, a diaphragm 15 of the release confirming valve 6 is pushed up, and the auxiliary air reservoir 2 and the expanding chamber 20 are communicated. Accordingly, compressed air in the auxiliary air reservoir 2 and a controlling chamber of the two pressure type control valve 1 flows into the expanding chamber 20 and diffuses, and the pressure drops, thus positively taking off the brake.

Title: Information recording medium and tracking error signal detecting device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/007
Filed: 1991-04-19
Abstract: PURPOSE:To supply an information recording medium in which the track density is twice compared to the conventional one and all tracks are connected continuously in a spiral form, by being present on an odd number of track discrimination mark for one track unit. CONSTITUTION:When the head is at a position A on the track 10a, the head obtains a positive tracking error signal from wobble paired marks 11,12. Next the head scans on the wobble paired marks 13,14 and they supply an opposite polarity of (negative) tracking error signal. Besides when the head scans for one period of the track, the head comes on an adjacent track 10b but the total number of the positive and negative wobble paired marks per one track period is an odd number, so the position of a positive wobble paired marks on the adjacent track comes to the next position C of a negative wobble paired marks on the advance track 10a.

Filed: 1990-04-03
Abstract: PURPOSE:To point out an input mistake by securing the difference between a display form obtained through the conversion carried out in a non-standard reading form and a display form obtained through the conversion carried out in a standard reading form. CONSTITUTION:A word dictionary stores the reading forms, the writing forms, the grammatical information, and the information showing the standard or non-standard reading forms opposite to each other. Then it is decided by reference to the word dictionary whether the KANA (Japanese syllabary)/KANJI (Chinese character) conversion is carried out in a standard or non-standard reading form. Then a normal display form is adopted when the standard reading form is applied. When the non-standard reading form is applied, the display form is inverted. Thus it is possible to point out the input mistakes of an input operator to ask him to reconsider the input operations, to prevent the wrong writing forms, and to omit the troublesome correcting operations after a print- out state.

Title: Semiconductor device
Inventor: ABE TAKASHI
IPC: H01L23/495
Filed: 1985-04-25
Abstract: PURPOSE:To reduce the dimensions of a package, reduce the variation of lead heights and realize stable soldering by providing grooves beforehand on the part of a lead to be bent. CONSTITUTION:Grooves are provided on the part of lead to be bent while the lead is still in a lead frame by punching in the case of the pressed frame and by half-etching in the case of the etched frame. With these grooves, the stress generated in the lead when it is bent is reduced and a small bending radius can be obtained without generating a stress in the boundary between a mold and the lead. Spring-back is also reduced. Moreover, bent positions can be previously processed with a high accuracy, As the grooves are made by pressing or etching, the variation of the lead heights is also reduced. Therefore, soldering can be stabilized and the reliability is improved.
