Title: Optical recording medium and production thereof
Inventor: SAITO KOICHI
IPC: G11B7/2433
Filed: 1984-12-13
Abstract: PURPOSE:To contrive enhancement of adhesion of a recording film to a substrate and long-time stability thereof, by a method wherein a tellurium oxide TeOx (0<x<1.0) is formed from a vapor of metallic Te passed through a plasma of an inert gas, an oxygen gas or a mixed gas thereof, and is oxidized in the plasma. CONSTITUTION:A high vacuum of not lower than 10<-5>Torr is provided in a vacuum tank, and a high-purity O2 gas, an inert gas or a mixed gas thereof is introduced into the tank to maintain a vacuum of 1X10<-4>-9X10<-3>Torr in the tank. Next, a voltage with 50-500W is impressed on a high-frequency exciting coil 4 to generate a high-frequency electric field, thereby exciting the gas to generate a plasma. An electric current is passed to a heating boat 2 to heat, melt and evaporate metallic Te 1, thereby depositing vapor particles onto the substrate. Some of the vapor particles of Te passed through the plasma are oxidized by collision with O ions or radicals in the plasma, and are deposited on the substrate together with unoxidized vapor particles to form a dense recording film.

Title: Control method for additional processor
Inventor: AOKI YOICHI
IPC: G06F15/16
Filed: 1985-11-27
Abstract: PURPOSE:To shorten the time needed for saving and recovery of arithmetic register data of an additional processor by detecting and deciding the use of the additional processor in case a shift request is delivered for the executing right to a program using the additional processor. CONSTITUTION:An OS 9 detects the use of an additional processor before a program A is started to set an executing state of the program A and holds the information on 'busy mode of additional processor' for an active period. The program A is saved to a system work area 10 where the due processing is interrupted by the control of the OS 9 and the OS 9 holds only the working environment data on the program needed when the processing is restarted. In this case, a state where 'the program A is using the additional processor' is stored in the OS 9. While the information showing that a program B 'does not use the additional processor' is stored in the machine words. Thus the OS 9 execute the comparison and decision between these two types of information and decides that no reservation is needed for the register data on the additional processor. Then the register data are not saved to the area 10.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for manual operation and to control the side face of an autonomously traveling vehicle to be parallel with a wall without picture processing by controlling a traveling direction so as to fix the distance between with the wall based on the output of a distance sensor. SOLUTION: A control circuit 15 controls driving motor 5a and 5b to drive in the direction of rotating forward and at the same speed and driving wheels 3a and 3b to rotate at the same speed so as to make the autonomously traveling vehicle travel straight. While traveling straight, the control circuit 15 monitors the output of an obstacle sensor 13 on the front of the autonomously traveling vehicle and at the time of detecting a front wall 20 anteriorly, stops the driving motors 5a and 5b and then rotates the autonomously traveling vehicle clockwise.  Continually, the control circuit 15 calculates the difference between the differences detected by direction sensors 9a and 9b, compares this distance difference with an extremely small prescribed value and when the difference is not more than the prescribed value, judges the autonomously traveling vehicle to be parallel with the face of the wall. Then the control circuit 15 synchronizes the driving motors 5a and 5b to drive rotating forward and makes the autonomously traveling vehicle travel straight nearly in parallel with the wall face.

Filed: 1994-10-28
Abstract: PURPOSE: To improve the operating efficiency by holding the extent of correction for the cloth fell position without causing a stop mark caused by the frame stop due to test weaving tried through a test weaving control circuit. CONSTITUTION: A test weaving control circuit 39 is connected to a control computer C0 of a loom. When a stop mark caused by the frame stop due to mispick is present, a stop mark test mode selecting switch 40 is operated to ON by an operator and the first test weaving in a prescribed amount is carried out through the test weaving control circuit 39. The loom is then automatically stopped to operate a delivery motor 1 by an extent set by a setting circuit 41 for the extent of correction for the cloth fell position after the passage of a time set by a setting circuit 42 for the stop time. The second test weaving is subsequently performed by a prescribed extent to automatically stop the loom. The presence or absence of the stop mark between the first and second test weavings is confirmed by the operator.  When the stop mark is present, the switch 40 is further turned ON to repeat the stop mark test until the stop mark is eliminated. Thereby, the proper extent of correction for the cloth fell position corresponding to the stop time is grasped.

Title: X-ray exposure apparatus
Inventor: MARUYAMA SHIGERU
IPC: H01L21/027
Filed: 1988-10-24
Abstract: PURPOSE:To prevent a temperature rise of a mask and a wafer by X-ray irradiation and to enable a fine pattern transfer by providing a thermoelectric cooling element on a wafer chuck. CONSTITUTION:A thermoelectric element such as a Peltier element 17 is provided on a wafer chuck 14. Heat generated in a mask 11 by X-ray irradiation is transferred to a wafer 13 through air 18 serving as a heat transfer medium and further transferred through the wafer chuck 14 and the Peltier element 17. Namely, the wafer 13 is not cooled indirectly through a ring but it is cooled directly from the downside of regions of the mask 11 and wafer 13 irradiated with the X-ray by eliminating heat from the region of the wafer 13 corresponding to the X-ray irradiation region. In this manner, the mask 11 and the wafer 1 can be prevented efficiently from temperature rise and thus from being affected by positional deviation due to thermal expansion. Accordingly, fine patterns can be transferred with high precision.
