Title: Check valve
Inventor: KARASAWA YUKIHIKO
IPC: F16K11/044
Filed: 2002-06-12
Granted: 2003-12-11
Abstract: This invention provides a check valve which eliminates the need for a coil spring and can increase a flow rate as a primary object thereof. The check valve includes a valve chest 12; a first conduit 13 and a second conduit 14 opened at opposing positions; valve seats 13a and 14a formed in valve chest side ends of the first and second conduits; a discharge conduit 15 opened in an intermediate portion between the two valve seats; and a valve element 16 movably provided between the two valve seats in the valve chest. The first conduit 13 and the second conduit 14 are automatically switched so that fluid can flow from the higher pressured conduit to the discharge conduit 15. At this time, there is no coiled spring in the flow passage, which thus enlarges the flow passage and eliminates the problem of a wear in the coil spring. Furthermore, the valve element 16 can be placed outside the flow passage, which also leads to the increase of the flow rate.

Title: Oscillator circuit, semiconductor device and semiconductor memory device provided with the oscillator circuit, and control method of the oscillator circuit
Inventor: OGAWA YASUSHIGE
IPC: H03K3/014
Filed: 2002-10-16
Granted: 2004-03-21
Abstract: There is provided an oscillator circuit capable of obtaining stable frequency by avoiding output having unstable frequency that is likely to occur to an operation/stop-control-feasible type oscillator circuit when oscillation begins. In such an oscillator circuit, an oscillation permitting signal (EN) sets an oscillator section in oscillation-operable state, whereby a controller section starts operation. The controller section that has stared its operation change an oscillation-frequency control signal (VR) into a signal value corresponding to predetermined oscillation frequency so as to set oscillation frequency at an oscillator section. Further on, the oscillator section outputs an oscillation signal in response to a detection signal (MON) that is outputted after a detector section compares a signal inputted therein with a predetermined signal value and detects that the inputted signal reaches a predetermined signal value. Thereby, transient state of an oscillation-frequency control signal (VR) can be detected. That is, there can be avoided an output of an unstable oscillation signal due to a transient oscillation-frequency control signal (VR).

Title: Fuse concept and method of operation
Inventor: HOENIGSCHMID HEINZ
IPC: G11C29/04
Filed: 2003-02-13
Granted: 2007-03-21
Abstract: It is difficult to fabricate a semiconductor memory device without any faulty memory storage cells. One solution is to produce more storage cells than needed on a device and faulty storage cells are replaced by the redundant storage cells. This solution requires that the addresses of the faulty storage cells, along with the replacement storage cells, be saved in a memory. The present invention teaches the use of non-volatile memory cells, particularly magnetoresistive random access memory (MRAM) cells, to store the addresses. Non-volatile memory cells can effectively replace the laser fuses currently used and also provides an advantage in the elimination of the laser fuse-burning step during the fabrication of the device.

Title: Freezing point and super control freezing point automatic measurement system
Inventor: TZOU HONG-KEE
IPC: G01N25/04
Filed: 2004-04-28
Granted: 2006-11-01
Abstract: Our invention of ""freezing point and super control freezing point automatic measurement system"" was based on the concept that the structure would be changed at the freezing point, and the electrical characteristics would reveal visible differences. Generally, the conductivity of sample is directly proportional to the temperature, which means the resistivity of testing sample increases with the decreasing of the storage temperature of the sample. In the resistance versus temperature plot, the curve should be a smooth exponential increase with the decreasing temperature. When the resistivity of testing sample varied significantly, the sample was also frozen at this temperature at the same time. We could in-situ measure the freezing point and the super control freezing point with a temperature recorder without the inspection through optical scope. We expect the preservation of sample at non-freezing region below the freezing temperature can prolong its preservation time without destroying its tissue.
