Title: Hydraulic power transmission coupling
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1988-12-09
Abstract: PURPOSE:To prevent a car from becoming impossible to travel and prevent a tight corner braking phenomenon by providing a mechanism permitting an orifice to be closed by a needle valve to lock a coupling when delivery pressure exceeds a specified value, and the coupling to be released from the locked state to recover a normal torque characteristic when the delivery is lowered. CONSTITUTION:When the rotating speed difference is produced between a cam ring 11 and a rotor 12, plungers 15 are pressed in the direction of a shaft axis to push out oil to a high pressure chamber 16A, and an inlet valve 20 closes an inlet passage 18. At this time, oil pressure is generated in the high pressure chamber 16A and plunger chambers 14 due to resistance of an orifice 23 to produce reaction force in the plunger 15. When the cam ring 11 is rotated against the reaction force, torque is transmitted in response to the speed difference. When the speed difference between front and rear wheels becomes larger and the pressure of the high pressure chamber 16A exceeds a fixed value, an orifice valve 24 is moved to the low pressure chamber 16B side, and the orifice 23 is closed by a needle valve 26 to lock the coupling.

Title: Spin coater and aging processing device
Inventor: SAKAI KOJI
IPC: H01L21/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To surely prevent gas leakage in a processing chamber, even under large pressure fluctuation by providing a processing-chamber pressure monitor for detecting pressure in a chamber. SOLUTION: An exhaust pipe 55 is connected to a processing-chamber pressure monitor 83 for detecting pressure in a processing-chamber S (i.e., in an exhaust pipe 55). There is possibility of leakage of ammonia vapor into the processing chamber S caused by the pressure in the processing chamber S becoming markedly higher than a vacuum chucking pressure in case the processing- chamber pressure monitor 83 detects the predetermined upper pressure limit. There is also the possibility of leakage of ammonia vapor in the processing chamber S caused by the lowered pressure in the processing-chamber S making no pressure difference for the vacuum chucking pressure, when it detects a prescribed lower pressure limit. Thus, an alarm-means issues an alarm and switches to a switching valve to cause N2 gas to fill in the processing chamber S. Exhausting in the processing-chamber is replaced by N2 gas.

Abstract: PURPOSE:To realize an A/D converter with high resolution in the A/D conversion with low cost by demultiplexing one analog signal and applying a different processing to the demultipelxed analog signals and sending the result to plural channels. CONSTITUTION:Suppose that a signal fluctuated in a range of -100%-+100% is inputted from a terminal A, a CPU 3 uses a signal B of a channel CH 1 as a digital value at a terminal A when the result of A/D conversion to the signal of the channel CH 1 is in the range of 1 count-(full count-1) count among the signals of each channel given to a multiplexer 1 from limiter circuits 71, 72, 73, 74 and uses the signal at a channel CH2 through A/D conversion and adds the result when the result shows full count. Thus, a digital value with a resolution of 2NXM is obtained, where M is number of channels of the multiplexer and N is number of bits of the resolution of the A/D converter, with respect to a signal given to the terminal A.

Title: Assay using template-depending nucleic acid probe reconstruction
Inventor: KEISU SHII BATSUKUMAN
IPC: C12Q1/00
Filed: 1988-12-12
Abstract: PURPOSE: To enhance sensitivity of assay ultimately by repeating the template dependent reconstitution quickly at a geometric series-like speed of excess probe sequence thereby increasing the sequence to be utilized for detection quickly. CONSTITUTION: A sample DNA is denatured and hybridization is performed. When T is present in the sample, T has high possibility to encounter P1 and P2 thus forming a part shown on the second drawing. Similarly, T' encounters P'1 and P'2 . This cycle is followed by addition of ligase which links the end of adjacent probes but does not link the plant end of DNA in the sample generally. After being linked, the sample is subjected to denaturing conditions and fused probes P1 -P2 , P1 '-P2 ' are produced. From this moment of time, the sample can be fed to a new cycle of hybridization-ligation-denaturing. Consequently, the sample is increased from one double chain template T1 -T'1 is increased to two double chain templates.
