Title: Method of monitoring cleanness of clean room
Inventor: FUJIE NOBUO
IPC: H01L21/66
Filed: 1991-12-02
Abstract: PURPOSE:To simply realize monitoring of cleanness by measuring a diameter of liquid droplet of a constant quantity dropped on a board placed in a clean room, and judging the cleanness in the room based on aging change of its measured diameter value. CONSTITUTION:A diameter of a liquid droplet of a constant quantity dropped on a board 10 placed in a clean room is measured. A board surface tension rS is high in a state that an upper surface 10a of the board 10 is clean, and the droplet 11 is extended. As a time is elapsed, when the surface 10a of the board 10 is contaminated, a reference surface tension rS is reduced, the droplet 11 is raised, and the diameter of the droplet 11 is reduced from D through D1 to D2. The aging change of the measured diameter value is compared with that when the cleanness of the room is normal. If it is the obtained value of the difference or less, it is judged that the cleanness in the room is normal. On the other hand, if the difference exceeds a predetermined value, it is judged that the cleanness in the room is abnormal.

Title: Control system for unmanned carrier
Inventor: SEKI TAKASHI
IPC: G05D1/02
Filed: 1988-12-19
Abstract: PURPOSE:To increase the freedom degree of control and to improve the driving efficiency of an unmanned carrier by giving the authorization to the carrier to move backward in case the interference time of the carrier is smaller than a prescribed set time to the following unmanned carrier at the backward movement. CONSTITUTION:When the backward movements are required to the unmanned carriers 2a and 2b, an interference time arithmetic part 7 operates the interference time to the carrier following the one to be moved backward. When the operated interference time is smaller than a prescribed set time, a backward movement authorization part 7 delivers the authorization for backward movement. Then a drive instructing part 7 gives a backward movement command to the carrier to be moved back. Thus the carrier receives the command and moves backward while transmitting a backward movement signal via a transmitter 18. Based on this backward movement, the following carrier stops and moves backward so that the backward movement signal received by a receiver 19 of the carrier is kept under the fixed intensity. Thus it is possible to increase the freedom degree of control and to improve the driving efficiency of the unmanned carrier.

Abstract: PROBLEM TO BE SOLVED: To provide an optical position measuring device capable of generating a reference pulse signal more reliably than the conventional technique even when the scanning interval is large or scattered light is incident. SOLUTION: This optical position measuring device largely diverging a beam bundle emitted from a light source uses relatively fine reference mark structural bodies 10, 20 on the side of a graduation plate M and a scanning plate A in relation with relatively coarsely patterned detecting elements D1-D3. Signals RIT and RIGT generated at the reference position are finally introduced to both input ends of a differential amplifier DIF to generate the reference pulse signal RIZ further processed arithmetically. Both input signals RIT and RIGT are subtracted from each other in the amplifier DIF to form the difference between both signals. The desired reference pulse signal RIZ is generated at the output end of the differential amplifier DIF, and the signal is transferred to an evaluation unit for further arithmetic process.

Title: New word registering method for dictionary editing device
Inventor: YODA NAOYUKI
IPC: G06F17/22
Filed: 1988-12-16
Abstract: PURPOSE:To improve the dictionary editing efficiency by reducing the information to be newly inputted by reference to the information stored in a translation dictionary. CONSTITUTION:When the data are inputted to a Japanese word dictionary 2 for registration of new words, the dictionary data items (headwords, parts of speech, detailed sorting, conjugations, connections, fields) are inputted to the dictionary 2 via a dictionary data input device 1. Thus a template data base 3 is retrieved every time the data are inputted to the device 1, and a template candidate which satisfies the input data conditions is selected. This selected candidate is offered to an operator who inputted the data and displayed on the screen of the device 1. As a result, the default value can be obtained from the data base by inputting a part of the entire dictionary information when a new word is registered into a translation dictionary. Thus the subsequent data input is not required in the case the default value can be used as it is. Then the dictionary information is registered with high efficiency.

Abstract: PURPOSE:To prevent erroneous data from being outputted<>by interrupting dynamic address translation processing, and simultaneously, informing an instruction processing part of this purport in the case that a bit field is set previously at the time of a mis-hit state. CONSTITUTION:At the time when the entry of a buffer TLB is updated by data read out from a memory device by a dynamic address translation(DAT) processing circuit 3, coincidence between a logical address from the instruction processing part and the logical address LA entered in the buffer TLB is detected by a coincidence detection circuit 1. Then, in the case that a second bit field CS to which new entry is intended is set previously at the time of the mis-hit state that the coincidence between a processing identification number from the instruction processing part and a first bit field PID given the entry is not detected by another coincidence detection circuit 2, the processing circuit 3 detects this, and interrupts the processing, and simultaneously, it informs the instruction processing part. Thus, the inconsistency of a process that the same logical address space is intended to be used is detected, and the occurrence of the erroneous data can be prevented.
