Title: Etching method for gap
Inventor: NAKADA TOSHITAKE
IPC: H01L21/306
Filed: 1980-12-26
Abstract: PURPOSE:To improve the accuracy of etching by thermally treating an etching mask obtained by depositing a silicon nitride film, a silicon dioxide film, an aminosilane film and a polyimide film on the surface of a GaP crystal during the interruption period of etching. CONSTITUTION:The silicon nitride film 11, the silicon dioxide film 12, the aminosilane film 13 and the polyimide film 14 are deposited successively on the surface of the GaP crystal 10. A window 16 is bored, the inside of the window is etched selectively by nitrohydrochloric acid while using the multiple film 15 as the mask for approximately 5 or 7min, and the etching depth of approximately 25mum is obtained. The GaP crystal 10 is washed by water and thermally treated, and etched by nitrohydrochloric acid again. Accordingly, since the etching mask is thermally treated during the interruption period of etching, the nitrohydrochloric acid permeating into the polyimide film is evaporated, a recovery effect through the vitrification of the polyimide film is displayed, and the generation of undesired etching is prevented.

Title: Method and device for nondirectory memory access protocol of decentralized and shared memory computer system
Inventor: HAGERSTEN ERIK E
IPC: G06F12/06
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To enable a node of a computer network to efficiently access a decentralized and shared memory in the network by disabling a home node to process other memory access requests regarding a memory block in a pending state. SOLUTION: A pending flag structure 410 is coupled with a network interface 406. The pending flag structure 410 stores a flag indicating that a memory block 408 is currently accessed by a network node and whether or not reading or writing by another node should be disabled. Once the pending flag is set, access from other network nodes to the relative memory block 408 is inhibited. When the pending flag is reset, the memory block 408 becomes usable in the case of the processing of a next transaction requesting the relative memory block 408.

Title: Probe for measuring thickness of suspended matter layer on surface of liquid material
Inventor: KOBAYASHI KIYOHIKO
IPC: G01B7/06
Filed: 1983-10-07
Abstract: PURPOSE:To improve accuracy by amplifying the electric resistance values measured respectively by plural electrode groups provided at a specified interval in the vertical direction on the outside circumferential surface in the lower part of a main unit at specified sequence and outputting the same to a connector. CONSTITUTION:Plural electrode pair groups 21-33 are independently provided at a specified interval in the vertical direction on the outside circumferential surface in the lower part of the main unit 5 of a probe 1 within the range where the part above the slag layer can be covered. A switch 19 is made pushable by a push rod 35 mounted to an insulator 34 at the bottom end of the main unit. The switch 19, the lead wires 39 of the groups 21-33 are connected via a signal processor 9 to a connector 11 connected to an external signal processing means (not shown). The analog multiplexer 16 in the processor 9 connects the groups 21-33 according to the specified sequence via an isolation amplifier 12 to the connector 11 by the signal from a shift register 15. The thickness of the slag layer is thus calculated from the difference in the electric resistance values between the slag layer and the molten metal.

Title: Pellicle frame
Inventor: SATO YUTAKA
IPC: G03F1/64
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to inspect the accuracy of patterns up to near a pellicle frame and the presence or absence of stuck dust by forming this pellicle frame of a material transparent to the inspecting light used for inspection with an optical inspecting machine. SOLUTION: The pellicle frame 1 consists of a glass, for example, quartz, which has, for example, a square shape and consist of the same compsn. as the compsn. of the substrate of a photomask. A pellicle 2 is stuck atop the pellicle frame 1 and the rear surface is adhered to the photomask. The glass of this compsn. is transparent to the inspecting light used in a coordinate measuring instrument of an optical system and, therefore, the pellicle frame 1 does not disturb the measurement of the patterns of the photomask. Scattering light is not vignetted by the pellicle frame 1 even in the case where the presence or absence of the sticking of the dust on the photomask is inspected in the state of mounting the pellicle 2 and, therefore, the inspection up to the part near the pellicle frame 1 is possible. Further, the pellicle frame 1 and the substrate consist of the same compsn. and consequently, the strain of the photomask due to the difference in the coefft. of thermal expansion between both does not occur.

Abstract: PROBLEM TO BE SOLVED: To eliminate danger of an operator by gradually reducing a speed difference of left and right traveling ceawlers in proportion to turning operation of a steering wheel as well as making an operational direction for turning the steering wheel constant even when a traveling machine body is changed over to forward and reverse. SOLUTION: Conformability of an operational direction and operation quantity of a second hydraulic pomp and a moving direction and a revolving angle of a steering wheel is attempted by revolving an operation part 101 on the other end of an arm 100 connected to an adjustable joint part 99 on a revolving block free to revolve through a support shaft on a yoke along a second shaft 93 at the time of carrying out turning operation by the steering wheel 81 by changing an inclined direction of the revolving block placed on the yoke to revolve around a first shaft 92 at the time of forward and at the time of reverse. Traveling speed is reduced and varied by transmitting revolving quantity of the steering wheel 81 to a drive shaft 90 from a small bevel gear 87 and a large bevel gear 88 and connecting a wire 22 to decelerating interlocking body 12 to be installed on the drive shaft 90.

Title: Waveform equalizing circuit
Inventor: OGAWA TAKUJI
IPC: G11B5/09
Filed: 1985-08-30
Abstract: PURPOSE:To reduce the reading error factor by extracting the read signal as a signal that has a small extension of an isolated waveform and no overshoot. CONSTITUTION:An input waveform 3 has a time shift after passing through delay lines 9a and 9b and turned into waveforms 3, 11 and 16. Both waveforms 3 and 16 are obtained at the output sides of adders 8a and 8b in the form of the outputs proportional to the input waveforms at a level higher than the fixed voltage V+ or lower than V-. The waveform 3 is impressed to the base of an npn transistor TR Q1 when the level gets out of the V+ and V-. In this case, a TR Q2 is turned on at a level lower than the V-. While a line 17 has no change. When the waveform exceeds the V+, the TR Q1 functions as an emitter-grounded amplifier. Thus it is possible to obtain a signal of adverse polarity which is proportional to the input waveform. When the waveform 3 has the downward polarity less than V-, a pnp TR Q3 works in the same way as the TR Q1. Thus the waveform 3 can be extracted at a level higher than V+ or lower than V- respectively.

Abstract: PROBLEM TO BE SOLVED: To prevent erroneous photographing and photographing irregularity from occurring by housing a film drawn out from a cartridge in a temporary housing part and guiding the leading edge part thereof toward the downstream side from the upstream side of the temporary housing part. SOLUTION: The whole of the already exposed film F is drawn out from the cartridge 20 and temporarily housed in the film temporary housing part 12.

Abstract: PURPOSE:To reduce a measurement error in a measured value of a base line, by providing a tubular air-interrupting member so that a space formed between a reticle (mask) and a projective optical system (contracted projection lens) be isolated from an outside air stream. CONSTITUTION:An air-interrupting tube 10 operating as an air-interrupting member is put on the end face portion on the reticle R side of the specular cylinder of a projective lens 1 to that it surrounds a projective optical path. Then, a reticle R is adsorbed on a reticle stage 2, and a wafer stage 4 is positioned so that a reference mark FM can be detected by a reticle alignment microscope 7.

On the occasion, the fluctuation of air is eliminated by the air-interrupting cylinder 10, a photoelectric signal delivered when the mark is detected is thereby stabilized, and thus a measured position is made very reliable.
