Filed: 1987-08-10
Abstract: PURPOSE:To realize a high-accuracy alignment operation against two or more layers by a method wherein a target pattern for alignment use is formed by composing the two or more layers and the alignment operation is executed by using the target pattern capable of obtaining the positional information on the two or more layers. CONSTITUTION:A first target pattern 1 is formed by a lithographic process of a first layer. Then, a second layer is aligned with the first layer; second targets 2 and 3 are formed by the lithographic process of the second layer. During this process, an error in the alignment of the second layer with reference to the first layer is expressed by a distance 5 between the central point 4 of the target patterns 2 and 3 and the target pattern 1. Then, an alignment operation of a third layer is executed by using the target patterns 1, 2, 3. If an error in the alignment of the third layer with reference to the first layer and the second layer is measured, the third layer can be aligned with an equal error with reference to the first layer and the second layer. By this setup, the alignment accuracy of two or more layers which are combined in an especially complicated manner can be enhanced; this setup is effective in high integration of an ultra LSI chip.

Title: Glide height measuring device
Inventor: HAGA SHUICHI
IPC: G01N19/08
Filed: 1990-07-26
Abstract: PURPOSE:To simplify a measurement, to reduce the price of a measuring instrument and to improve accuracy for the measurement by changing the rotating number of a magnetic recording medium, measuring the floating amount from the rotating number starting the change of friction force with this magnetic recording medium and measuring a glide height. CONSTITUTION:When gradually increasing the rotating number from the state of stopping a magnetic recording medium 1, a slider 3 is gradually slide from a contact state to the surface of the magnetic recording medium 1, the floating amount is increased and with this increase, the frictional force is reduced. In the state that the slider 3 does not get contact with the surface of the magnetic recording medium 1, friction caused by only air resistance is received and therefore, the frictional force is held constant at a small value. Accordingly, when measuring the rotating number when this frictional force is rapidly changed, the floating amount corresponding to this rotating number is the glide height, namely. Thus, the glide height is measured, it can be directly measured since the measured value is the frictional force, and error can be suppressed low.

IPC: B65H29/24
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To manufacture a device with a little manufacturing cost by inserting a hollow rivet as a blow nozzle into a plurality of holes in a pipe wall of a blow pipe. SOLUTION: The pipe wall of a blow part 16 has a plurality of holes extending in series in the pipe axis direction with one hollow rivet as a blow nozzle 20 inserted into each hole. In order to produce the blow nozzle 20, it is advantageous to insert the hollow rivets having a flat circular head into holes drilled in the pipe wall.

IPC: G06F11/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown of the block chain of a buffer loop that is caused by the double return of the buffer block of a user program. SOLUTION: A buffer management means 12 receives a buffer acquisition request from a user program 11 and compares a program identifier with a wrong program identifier list 17 to reject the received request if the program identifier is coincident with any wrong program identifier of the list 17. The means 12 also receives a buffer return request from the program 11 and decides whether a block 201 is used via a buffer state check means 15 and by means of a program identifier 194 of the block 201 of a buffer loop 10. If the block 201 is not used at present, the double return of the block 201 is decided. Thus, the identifier of the program 11 that had a return request is registered in the list 17 and the buffer return request is rejected.

IPC: H03K5/135
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a clock forwarding circuit and method for a semiconductor integrated circuit that has an operation timing margin of a data reception edge increased and reduces a power consumption. SOLUTION: On the basis of a delay sending clock DSCLK communicated from a data sending edge at the time of abnormal operation of a circuit, the amount of delay by a data line in a data reception edge is acquired and a reception clock RCLK is generated. Then, at the time of normal operation of the circuit, the RCLK generated at the data reception edge is responded and received. Thus, since data are received in response to the RCKL generated by acquiring the amount of wire delay of the data line in advance, an operation timing margin at the data reception edge increases. Also, according to this clock forwarding circuit, since the clock line is deleted and a sending clock SCLK is supplied with the data reception edge through a data line 207 only when the semiconductor integrated circuit is in abnormal operation state, a power consumption is reduced.
