Title: Manufacture of semiconductor processed part
Inventor: HASEGAWA TOMOYASU
IPC: G01C19/5769
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacture, in which movable electrode is not brought into contact with a semiconductor substrate during a drying process or due to vibration impact and manufacturing process steps are simple. SOLUTION: A sacrificial layer is formed on a semiconductor substrate 1, and a semiconductor layer is formed on the sacrificial layer on the semiconductor substrate 1. The intermediate layer of the sacrificial layer is easier to etch than its upper and lower layers. The semiconductor layer is processed to form a movable electrode 6 and the like.

Title: Structure of truck of flying cutter for spiral steel pipe
Inventor: TAKADA KAZUHIKO
IPC: B23K7/00
Filed: 1990-10-24
Abstract: PURPOSE:To prevent the deviation in the axial direction of a spiral steel pipe and to eliminate the dislocation of cutting by bringing an endless band-shaped body elastically along the outer peripheral surface of the spiral steel pipe in tight contact therewith, thereby putting both into a surface-to-surface contact without relative slips. CONSTITUTION:A caterpillar 18 as the endless band-shaped body consisting of roller chains 15, plate bodies 16 and rubber bodies 17 is brought into tight contact with the outer peripheral surface of the spiral steel pipe 2 and can be circumrotated within the plane orthogonal with the pipe axis as the spiral steel pipe rotates. In addition, the endless band-shaped body comes elastically into tight contact with the outer peripheral surface of the spiral steel pipe 2 in the surface-to-surface contact and can be put into not a rolling state by a point contact but a fixed clamp state. The track is, therefore, made to travel together with the spiral steel pipe in the pipe axial direction while the deviation in the pipe axial direction is prevented and while the component in the rotating direction of the spiral steel pipe is escaped. The generation of the dislocation in the cutting is obviated in this way and the dealing with even the spiral steel pipes of different diameters is possible while the relative surface-to-surface contact free from the relative slips is assured by the endless band-shaped body.

Abstract: PURPOSE:To increase readout speed by providing a voltage limit circuit which limits a potential difference between pairs of string lines by operating a pair of column lines so as to control other column line potential with each other in a data readout period. CONSTITUTION:In a voltage limit circuit in which column lines 13 and the inverse of 13 are connected with each other, two N-channel enhancement type MOS transistors 17 and 18, the drain and the gate of which are connected with each other, are connected in parallel so as to connect a drain and a gate on one side to a source on the other side. When one memory cell 11 is selected based on the selection signal WL of a row line wire 12 corresponding to an address, data,s Q, Q are read out at the pair of column lines 13 and the inverse of 13, and the potential difference between the string lines 13 and the inverse of 13 is expanded rapidly, however, it is limited with a voltage limit circuit 16, and it is controlled below the threshold voltage VTH of the transistors 17 and 18. Next, when the data is read out, since a difference between the potentials of column lines at a low potential side and a high potential side is small, it is possible to reduce a data readout time.

IPC: A63F7/02
Filed: 1993-10-23
Abstract: PURPOSE:To prevent the condition where only an expert easily generates a bonanza so as to easily generate the next bonanza by voiding the function of a stop command signal generating means, for example, during an ordinary game under a fixed condition during a variable game, and validating the func tion of the stop command signal generating means during the high probability condition of a special picture or a general picture. CONSTITUTION:When the power is applied to a pachinko game machine, a stop command signal control means 400 executes a main routine, and sets the normal processing. In this processing step, the function of a stop switch 27 is stopped. When it enters a sub-routine of a pattern variation processing of the main routine to be in the process of increasing the bonanza probability, the function of the stop switch 27 is validated. Thus, if there is no bonanza advance or waiting notice, a game player can again extract a bonanza random number by pressing the stop switch 27 to the starting memory of a failure. Accordingly, the bonanza generation chance can be increased.
