Title: Wafer heat-treating apparatus
Inventor: NAGASAKI SHINICHI
IPC: H01L21/677
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To detect thermal deformation of a reaction tube without fail by projecting light on a wafer or wafer boat and receiving reflected light from the wafer or boat. SOLUTION: A wafer boat 30, having a wafer 32 mounted thereon, is set at a specified position in a reaction tube 10, an emitting-means 24 is actuated to emit light and to project it on the wafer 32, and receiving-means receives normally the reflected light from the wafer. If the tube is thermally deformed, the receiving-means will not receive the reflected light or the received light quantity will decrease because of the boat 30 being inclined in the tube 10. Thus it is possible to easily and sufely detect the thermal deformation of the tube 10 and prevent the reduction in the production yield, due to the characteristic change of a semiconductor device.

Abstract: PURPOSE:To make rolling pitch minimum, and to improve rolling efficiency, when the operating conditions of each rolling installation for a succeeding material are changed, in a continuous rolling plant, by choosing, as the rolling pitch, the maximum value among set times required for the change obtained in specifying each rolling installation. CONSTITUTION:In a figure where abscissa shows a position of each rolling installation and ordinate shows a time, curves L1, L2 shows respectively the rolling schedule of a preceding material and a succeeding one. In case of changing the operating conditions of each rolling installation for a succeeding material, a rolling pitch from the passing of the tail end of a preceding material to the receiving of the front end of the succeeding material is controlled to the minimum. For this purpose, a maximum speed, in the meantime till said conditions attain an accelerating and decelerating rate and a changing extent required for said changing in each installation, is obtained, and an accelerating and decelerating time required for the change of each installation is obtained from both of the rate and the changing extent. Further, a time of constant speed in which the maximum speed is kept in each installation is obtained from the changing extent, maximum speed, and accelerating and decelerating time, and then a set time required for the change of each installation is obtained from the sum of the time of constant speed an the accelerating and decelerating time mentioned above. And a maximum value A is chosen among respective set time to use it as a rolling pitch. Thus, the curve L2 is shortened in comparison with a broken line expressing a conventional example.

IPC: F16K15/14
Filed: 1981-11-11
Abstract: PURPOSE:To reduce the shock added to a valve seat by means of a valve plate by increasing the area of a valve seat face corresponding to the maximum lift part of the valve plate more than other seat faces in a valve seat provided with valve ports between ring-shaped seat faces with large and small diameters. CONSTITUTION:A valve seat 11 is provided with large-diameter ring-shaped seat faces 12 and small-diameter ring-shaped seat faces 13, and several valve ports 5 are bored between them. Between neighboring valve ports 5, a connecting seat face 12' is formed to connect both seat faces 12 and 13. A valve plate placed on this valve seat is fast fixed at its center part and lifted from the valve seat in its periphery to permit gas circulation. Naturally, a part of the valve seat corresponding to the maximum lift part of the periphery is damaged badly due to the return shock of the valve plate. In this invention, the area of the valve seat face corresponding to the maximum lift part is made larger than the others to reduce the impact stress caused by the valve plate.

Title: Jig for wafer transport
Inventor: TAGAMI KAZUNORI
IPC: H01L21/68
Filed: 1986-07-29
Abstract: PURPOSE:To eliminate the need to dismantle wafer stoppers whenever the size of a wafer to be transported is changed and to prevent damage and displacement of wafers in following processes by a method wherein a group of wafer stoppers is rotated and a required wafer stopper is fixed. CONSTITUTION:After the size of a wafer to be transported to a jig 5 has been confirmed in advance, a rotary table 1 equipped with wafer stoppers is rotated about its central axis so that the size of a wafer to be transported can correspond to the size of a wafer stopper. For example, a wafer stopper 1a for a 6-inch wafer is turned toward the direction of a vacuum chuck 2 and is then fixed by means of a fixing pin 4. If a required wafer stopper is fixed in this manner, the center of a wafer which is transported from the direction A is sucked onto the vacuum chuck 2 and is fixed temporarily. Through this constitution, it is possible to remove any inconvenience to dismantle a wafer stopper and to exchange it for another so that its size can correspond to the size of the wafer.

The water collecting section can thus be separated from the water draining section, and water in the ground can be effectively collected and drained in a short time. The effective water collecting and draining effect can be continued for a long period of time.

Abstract: PURPOSE:To carry out the initialization so as to realize the transaction and register with another bankbook in case a correct bankbook is not inserted for a period longer than a prescribed time, by monitoring the time when the next bankbook is inserted while a bankbook is returned for the transfer of the page. CONSTITUTION:A resistering machine PP of an automatic transaction device ATM prints the print data equivalent to a page on a bankbook PB and then discharges the bankbook to an inserting slit to urge the transfer of the page and also to start a timer TM. If a customer takes out his or her bankbook and then inserts it again after the transfer of the page within a time set by the timer, the account number is read to be compared with the account number stored in a memory MEM. Then the timer TM is reset when a coincidence is obtained through the above comarison. After this, the print data is transferred with control between a center CNT and the machine PP. Then the data is printed on the next page by the machine PP. If the timer TM detects that no bankbook is inserted again for a period longer than a prescribed time since the discharge of a bankbook, the memory MM is cleared to carry out the initialization for the next transaction.
