Title: Grooving method and grooving device
Inventor: SAKAI KAZUAKI
IPC: H01L21/301
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To realize accurate grooving by combining a measuring device for measuring a height of the upper surface of a work with a grinder using a grinding stone blade. SOLUTION: In such a state that a work 2 of 4-inch silicon wafer with a thickness of 1mm is set to a chuck 1 having the upper surface inclined 8 degrees against the horizontal surface, the change in height of the upper surface of the work 2 is measured by a contact type shape measuring device 3. Then the device 3 is combined attachably and detachably to a grinder having such a structure comprised of a grind stone blade 6 which rotates at a high speed and grooves the upper surface of the work 2 at constant depth and width. Thus, the change in depth of groove from the upper surface thereof can be kept within a range of ±0.3μm accurately in the entire parts of the work 2.

Title: Ultrasonic flowmeter
Inventor: ADACHI AKIHISA
IPC: G01F1/66
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To improve the safety of a flowmeter by sealing a piezoelectric body in a fire-blocking metallic case and adjusting the potentials at the metallic case and a flow rate measuring section to a same value. SOLUTION: When a high voltage is applied across electrodes 20 and 25 of a piezoelectric body 18 or a very large quantity of charges is accumulated in the body 18, while, for example a high voltage generated by thunder is impressed upon a piezoelectric body 18 or charges are accumulated in the body 18, discharge may occur between the electrodes 20 and 25 or between the electrode 25 and a case 19. Since the piezoelectric body 18 is sealed in the case 19 which is constituted in such a way that an LP gas cannot infiltrate into the space 28 in the case 19, the LP gas does not catch fire even when the discharge occurs.  In addition, the potentials at an ultrasonic vibrator arranged in a flow rate measuring section and the sidewall section of the case 18 become equal to each other, because the vibrator and sidewall section are electrically connected to each other through a conducting means. For this reason, the occurrence of a discharge between the ultrasonic vibrator which is in contact with the LP gas and a vibrator attaching hole can be also prevented.

Title: Method for sampling minute amount of specimen for automatic analyzer
Inventor: YOKOSE TAIZO
IPC: G01N35/10
Filed: 1991-09-04
Abstract: PURPOSE:To sample a minute amount of specimen efficiently and highly accurately by detecting the level of a sample-shortage detecting region with a sample probe, which also serves the role of a liquid-level sensor, and controlling the depth of the tip of the probe and the driving of a syringe. CONSTITUTION:A sampling arm 5 is driven 6. A sampling probe 4, which also serves the roles of a liquid level sensor and a sampling nozzle, is brought into contact with the liquid surface of a specimen in a sample cup 10b, and the specimen is sampled. When the amount of the specimen is as minute as about, e.g. 20-30mul, the tip of the probe 4 is inserted down to the bottom of the cup 10b. Therefore, there is no dummy amount of the specimen, which is caused by the difference between the heights of both tips of the sensor and the nozzles, at all. The tip of the probe 4 is inserted beneath the liquid surface by the amount of the level after the tip of the probe 4 comes into contact with the liquid surface based on the level information in a sample-shortage detecting region from the bottom of the cup 10b. Therefore, the specimen is not attached. When the total amount of the specimen becomes lower than the maximum amount of the apparatus, the driving of a specimen sampling syringe 1 is controlled, and the sucking of air is prevented. Therefore, the sampling accuracy can be maintained.

Title: Substrate cleaning equipment
Inventor: HIRANO KATSUHIKO
IPC: B08B3/10
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To enable a substrate to be kept high in cleanness without causing damage to it by a method wherein a cavitation air bubble holding means that holds cavitation air bubbles near the surface of the substrate until they burst is provided. SOLUTION: When water of high pressure is spouted out from a nozzle 12 against a transfer carrier 2 in a cleaning tank, cavitation air bubbles are generated owing to a pressure difference between surrounding water and spouting water and a shearing action. When a jet of water 21 accompanied by active cavitation flows between substrate 1, it collides against projections 22 provided inside a transfer carrier 2 as cavitation air bubbles. As a result, cavitation air bubbles staying in a jet of water 21 are made to stay around the projections 22 without passing along the surface of the substrate 1. The cavitation air bubbles staying around the projections 22 grow gradually bigger and burst, and foreign objects attached to the surface of the substrate 1 are removed by a burst pressure induced by bursts of cavitation air bubbles. As mentioned above, a cleaning effects is produced.

IPC: H04N1/393
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To continue a read operation as much as possible even in the case that the residual amount of a memory becomes little and the memory overflows and to prevent extreme degradation of image quality further. SOLUTION: Even in the condition that the memory overflows by reading an original when the residual amount of the memory is little (Y of S4), the image data of the original are reduced and read by a readable magnification larger than a reduction limit magnification set beforehand (Y of S10 and S11) and stored in the memory (S6). Thus, the read operation is continued as much as possible and extreme degradation in the image quality is prevented further. As a result, memory overflow is positively avoided and the work time and handling time by a user further shortened.

Abstract: PURPOSE:To prevent a diaphragm from being damaged by the cavitation by sealing a fluid not including a gas in an introduction part of a to-be-measured fluid thereby not to impress the to-be-measured fluid directly to a pressure detecting part of the diaphragm. CONSTITUTION:In this sensor, a thin film part 14 such as a strain gauge or the like is provided at one face of a pressure detecting part 11a of a metallic diaphragm 11, thereby to detect the pressure. At this time, the space 10 below the pressure detecting part 11a is tightly sealed by a metallic thin plate 12, and therefore a fluid 13 which is not corrosive without including the air is sealed. Accordingly, a to-be-measured fluid 4 is prevented from being directly pressed to the pressure detecting part, 11a. The erosion of the pressure detecting part 11a due to the cavitation is thus avoided. The fluid 4 to be measured is impressed to the thin plate 12 and the cavitation generated in the fluid 4 is let away to the thin plate 12 which is resistant to the cavitation. A highly reliable sensor is realized without any restrictions for the fluid 4.
