Title: Substrate treatment apparatus
Inventor: KOYAMA YOSHIHIRO
IPC: H01L21/304
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To surely detect the breakage of a bellows pump which sends a treatment liquid through application of a pressure. SOLUTION: A bellows pump 25 sends a chemical by application of a pressure toward a nozzle 22 from a chemical tank 23 through a chemical supplying route 24. In the chemical supplying route 24, a trap tank 26 is provided. If bubbles are produced in the chemical supplying tank 24, the liquid level in the trap tank 26 lowers. If the liquid level goes down to that of a liquid level sensor S1, an air valve 42 for bleeding air is opened. As a result, the liquid level in the trap tank 26 rises again. But, if a compressed air gets mixed in the chemical supplying route 24 by the breakage of the bellows pump 25, lowering of the liquid level does not stop even by the opening of the air valve 42. Consequently, it is judged that the bellows pump 25 is broken, if the liquid level becomes lower than the liquid level sensor S2.

Title: Synthetic quartz glass for optical member and its production
Inventor: IKUTA YORISUKE
IPC: C01B33/18
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To give excellent UV-resistant characteristics to a quartz glass which can be used for the light from the UV region to the vacuum UV region by keeping the synthetic quartz glass in a specified temp. range to obtain specified viscosity of the glass. SOLUTION: The synthetic quartz glass is kept in a temp. range from <=T1( deg.C) to >=(T1-200 deg.C) so as to obtain 1014.5 poise viscosity of the glass, wherein T1 is the so-called distortion point, ranging from 900 to 1200 deg.C for a normal synthetic quartz glass. The glass is kept in the above temp. range preferably for about >=10 hours and about <=800 hours in a nitrogen gas or rare gas (e.g. helium) atmosphere. In order to improve the optical homogeneity and to suppress distortion, the glass is kept at the temp. above described and then preferably cooled to (T1-500 deg.C) at <=50 deg.C/hr cooling rate. The obtd. synthetic quartz glass satisfies the relation of I1/I0<=0.57 and I2/I1<=0.14, wherein I1, I2, I0 are scattering peak intensities at 495 cm-1, 606 cm-1 and 440 cm-1, respectively, in the laser Raman spectrum.

Title: Manufacture of driving belt for belt-driven tape cartridge
Inventor: KURIWADA TAKESHI
IPC: G11B23/087
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To industrially obtain a driving belt the tension of which hardly deteriorates from a thermosetting resin by continuously cutting a sheet from the outer periphery of a cylindrical molded body formed by curing the thermosetting resin and obtaining the belt by elongating a ring-like body punched from the sheet. SOLUTION: A sheet 4 is continuously obtained by rotating a metallic shaft 1 while a blade 3 is pressed against a molded body 2 formed by curing a thermosetting resin put around the shaft 1 in a cylindrical shape. It is preferable to use a thermosetting polyurethane exhibiting rubber elasticity after curing as the thermosetting resin. It is also preferable that the resin has a rubber hardness of >=90 A, because it becomes hard to cut the sheet 4 as thin as <=0.5 mm when the rubber hardness is <90 A. Then a doughnut-like ring is punched from the sheet 4 thus obtained and a driving belt is obtained by elongating the ring. Therefore, the thin thermosetting polyurethane sheet 4 can be manufactured industrially and a driving belt the tension of which hardly deteriorates can be obtained industrially.

IPC: G03B13/14
Filed: 1987-12-22
Abstract: PURPOSE:To correct parallax with simple adjustment by adjusting the position of a part of an objective lens system in a plane perpendicular to the optical axis of a finder. CONSTITUTION:Luminous flux from an object which passes through the objective lens 10 is made incident on a 1st prism 3 and vertically deflected to form the image of the object near a visual field frame 5. The luminous flux with which the image of the object has been formed in deflected on a 2nd prism 4 and passes through an eyepiece lens 6, then attains an observation pupil 7. Then, the correction of the parallax is performed by adjusting the position of the entire objective lens 10 or either lens group 1 or lens group 2 of the objective lens in the plane nearly perpendicular to the optical axis of the fiber. Thus, the parallax can be excellently corrected in a simple method.

Title: Warning device for change rate of process monitoring device
Inventor: KAWAMOTO JUNICHI
IPC: G05B15/02
Filed: 1993-12-24
Abstract: PURPOSE:To prevent many non-important alarms from being issued by predicting the change rate of monitor data during the next control term by the use of the monitor data in the past time sequentially recorded and held in a data memory in a time series manner. CONSTITUTION:A critical change rate alphaC in the next control term TC is calculated from the tendency of respective result change rates alphaLalphaM1-alphaM3, alphaS of a long term TL, middle terms TM1-TM3 and short term TS in the monitor data of respective equipments 4 for prescribed terms stored and held in the data memory of a hard disk in a time series manner. Namely, a monitoring person conventionally observes the monitor data in the past and judges the critical change rate for the next control term TC, but in this case the optimum critical change rate is automatically set. Therefore, even when the change rate alpha of the monitor data tends to increase or decrease in the manner of a middle term or long term, the critical change rate is automatically changed according to the tendency.

Title: Semiconductor integrated circuit device
Inventor: KOYAMA HIDEAKI
IPC: H03F3/50
Filed: 1993-12-24
Abstract: PURPOSE:To avoid the fall or the potential or an input terminal even at the time of turning off an amplifier to prevent a protective diode from being turned on regardless of input of a large-amplitude signal by adding a transistor TR which turns on/off the TR of a base-earthed amplifier. CONSTITUTION:When a switch 1 is turned on, the input signal from an input terminal 1 flows to a TR 5 because a base potential VB1 of the TR 5 of the base-earthed amplifier is higher than a base potential VB2 of a TR 7, and this circuit is operated as an amplifier. When the switch is turned off, the emitter potential of the TR 5 is raised and the TR 5 is turned off, and the current of a constant current source 3 flows to the TR 7 side, and the circuit is turned off as the amplifier. At this time, the potential of the input terminal 1 is fixed to VB3-VBE (VBE is the potential difference between the base and the emitter of the TR 7 and is about 0.7V). Therefore, since the potential of the input terminal 1 is not reduced when the amplifier is turned off, protective diodes 14 and 15 are not turned on even at the time of input of a large-amplitude signal.
