Title: Method and apparatus to provide dynamic ultrasonic measurement of rolling element bearing parameter
Inventor: BROWNER RICHARD W
IPC: G01L5/00
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for measuring real time dynamic stress, temperature, and speed of a bearing by using ultrasonic wave. SOLUTION: The device and method are used to measure a multipul operation parameters of the rolling element bearing by transmitting an ultrasonic acoustic signal across the laces of the bearing. This device transduces a first electric signal into an acoustic signal by a transducer in the form of PZT (Lead Zirconate Titanate) crystals. The acoustic signal is alternately received by side faces of the bearing laces and transduced by a second transducer into a second electric signal. The first and second electric signals are compared with each other with respect to time in order to determine the time of flight of the acoustic signal crossing the bearing. The time of flight of the continuous acoustic signal is then transduced into values corresponding to stress, temperature, and speed of the bearing.  As an alternative, a single PZT crystal is used as a transducer for transmitting the acoustic signal and receiving the acoustic signal reflected from the opposite side of the bearing. The stress, temperature, and speed of the bearing are calculated from half the time between the transmission and reception of the acoustic signal.

Title: Developing device
Inventor: HASHIMOTO TATSUAKI
IPC: G03G15/08
Filed: 2001-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a developing device equipped with a developer restricting member cooling means which does not necessitate installation of a large size peltier element for cooling the developer restricting member, and prevents scattering of the developer by directly jetting air. SOLUTION: The developing device 1 has a developing container (developer housing means) 4 housing a powder developer, a roller-like developing sleeve (developer carrying means) 3 carrying the developer on the surface rotatably supported by the developing container 4, and a developing blade (developer layer thickness restricting means) 6. A heat pipe 8 is abutted to the surface of the developing blade 6, and the peltier element (cooling means) 9 is disposed on a part of the heat pipe 8. Since the heat of the developing blade 6 can be moved by the heat pipe 8, it becomes possible to cool at the part apart from the edge part of an image forming device body of the developing device 1, and thus scattering of the developer can be prevented due to reduction of the influence of air by a fan F to the developing device 1.

Title: Multi-lens and multi-ccd type image pickup device
Inventor: ADACHI YUKIHIRO
IPC: H04N9/09
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a multi-lens and multi-CCD type image pickup device capable of realizing improvement of the performance of the whole image pickup device and a reduction in the cost. SOLUTION: The multi-lens and multi-CCD type image pickup device is provided with image pickup elements 4, 5, 6 for R, G, B each having a light- receiving surface of the same size and processing circuits 7, 8, 9 therefor. The number of pixels of the image pickup element 6 for B is reduced compared to the number of pixels of image pickup elements 4, 5 for R, G. Conventionally, a gain of a processing circuit of a B channel is much larger than that of a G channel, and this causes the deterioration in the S/N(signal to noise) ratio of a chroma signal. However, in the above-mentioned constitution, since the sensitivity of the image pickup element for B is larger than those of image pickup elements of R and G, the gain of the processing circuit of B can be made to be small, thereby improving the S/N ratio of the chroma signal.

IPC: F16H25/12
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a zoom device capable of smoothing the change of zoom magnification at the time of switching from digital zoom to optical zoom. SOLUTION: The optical zoom is realized by moving a zoom lens 22 by a motor for zoom 24, and the digital zoom is realized by performing digital processing to an image signal by a digital zoom circuit 30.

Therefore, the motive power of the motor 24 is immediately transmitted to the lens 22 when the digital zoom is switched to the optical zoom, so that zoom operation at the time of switching is smoothed.

Title: Method for manufacturing pure water
Inventor: HIRAYAMA JUNYA
IPC: B01J49/00
Filed: 2001-06-11
Abstract: PROBLEM TO BE SOLVED: To manufacture pure water of high purity in which concentration of silica and other ions are remarkably reduced by effectively regenerating a strongly acidic cation exchange resin and a strongly basic anion exchange resin when pure water is manufactured by making water containing silica pass through a mixed bed system ion exchange resin tower in which the strongly acidic cation exchange resin and the strongly basic anion exchange resin are mixedly packed. SOLUTION: When adsorbing quantity of silica of the strongly basic anion exchange resin reaches 0.5 to 2.5 g-SiO2 /L-strongly basic anion exchange resin, a water flowing process is shifted to a regenerating process. In this regenerating process, a strongly basic anion exchange resin regenerating agent is made to pass through a resin layer 1A of a mixed state in the mixed bed system ion exchange resin tower 1, then backward washing water is introduced upward to the resin layer of the mixed state in the mixed bed system ion exchange resin tower to separate the resin layer of the mixed state to a strongly basic anion exchange resin layer 2 and a strongluy acidic cation exchange resin layer 3. Then, a strongly acidic cation exchange resin regenerating agent is made to pass through the separated strongly acidic cation exchange resin layer.
