Title: Flow control valve
Inventor: SUDO SATOSHI
IPC: F16K3/34
Filed: 2000-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce generation of noise due to cavitation phenomenon. SOLUTION: This flow control valve comprises a valve body, a spool, and a first chamber and second chamber defined via the spool. The valve body at the second chamber side has an inner peripheral groove 26, extended in the circumferential direction on a reciprocating and sliding central line of the spool, and the inner peripheral groove 26 has three passage holes 27 which are arranged at uniform circumferential angle intervals β (120 degrees) to each other. The spool has two throttle holes 25, capable of communicating the inner peripheral groove 26 and the first chamber at uniform circumferential angle intervals α (180 degrees). The rate of flow passing through the first chamber and the second chamber through throttle-holes 25 can be changed by the reciprocating sliding of the spool.  Considering it being unavoidable in assembling that one throttle-hole 25 and one passage hole 27 are faced to each other, the generation of noise caused by cavitation phenomenon there is permitted. But throttle- holes 25 other than this and the passage holes 27 are located, so that they do not mutually face.

Inventor: NAGAOKA MASAHIRO
IPC: F02D29/06
Filed: 2000-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a speed controller of an engine for generator capable of easily synchronizing an engine generator with a commercial power supply, preventing a back flow when systems are linked to each other, and providing an economic effect by the introduction of the engine generator. SOLUTION: This speed controller 10 of the engine for generator is used in a parallel operating device 1 capable of performing a parallel operation of the engine generator 2 and the commercial power supply 3. The speed controller 10 comprises a speed variation variable means 15 capable of varying the speed variation of the engine generator when a load increases or decreases at the time of synchronizing operation when the engine generator 2 and the commercial power supply 3 start the parallel operation and during the parallel operation. Since the speed controller can increase the time required to synchronize the engine generator with the commercial power supply, and prevent backflow, the engine generator can be prevented from stopping.

IPC: G02B15/20
Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a high variable power zoom lens whose lens barrel structure is simplified and which has high performance. SOLUTION: This variable focal distance lens system is provided with three lens groups G1, G2 and G3 in order from an object side. When the respective lens groups are moved from a wide-angle end state to a telephoto end state, they are moved in such order as an infinity focusing state in the wide-angle end state to a short-distance focusing state in the telephoto end state, and a focusing distance is gradually changed to a short distance according as the respective lens groups are moved from the infinity focusing state to the short- distance focusing state. The lens group G2 has an aperture diaphragm S and lens components are arranged on the object side and an image side by putting the diaphragm S in between.  When the respective lens groups are moved from the wide-angle end state to the telephoto end state, the lens groups G1 and G2 are moved so that their moving ratios may be always constant, and the lens group G3 is moved with respect to the lens group G2 so that space between them may be widened from the infinity focusing state to the short-distance focusing state, and it may be narrowed from the short-distance focusing state to the adjacent infinity focusing state.

Title: Liquid crystal display device
Inventor: NAMAE ISAO
IPC: G09G3/20
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To display a picture having no noise and high quality and also to reduce driving power even in the case of a liquid crystal display device having a large number of pixels. SOLUTION: In this display device, a picture is displayed by converting an inputted digital video signal into an analog video signal in a pixel unit by using a ramp wave-form and applying the obtained analog video signal of the pixel unit to pixels via a switch turning the signal ON/OFF with pixel transferring pulses of a vertical shift register. As a result, since the digital video signal is converted into the analog video signal in the pixel unit in the inside of the device, it is unnecessary to divide the video signal and to scan the divided video signals and also the reflection at the time of inputting the video signal to the device is not present and, thus, the picture having no noise and high quality is displayed and also drive power is reduced in this device.

Title: Apparatus for reproducing recorded information
Inventor: TONAMI JUNICHIRO
IPC: G11B20/10
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a differential signal cannot be dealt with because the filter factor of a variable coefficient filter is conventionally updated so that zero cross sample data converge on 0, convergence is slow, there is much misjudgment, Viterbi decoding cannot be performed because partial response equalization is not performed, and the compatibility of a system to integral and differential signals cannot be realized. SOLUTION: Information used for cross talk elimination in a characteristic mode is selected from either zero-point information or peak point information. A temporary discriminant circuit performs temporary discrimination (convergence target setting) on condition of partial response equalization on the basis of peak point information and state transition. An error signal is controlled to be 0 by making the difference of a temporary discrimination value and a reproduced signal after waveform equalization into the error signal. The operation of an apparatus can be converged on a clear value, a pseudo-crosstalk signal based on a reproduced signal from an adjacent track is outputted and subtracted from the reproduced signal from a regenerative track.

Title: Update system for multiprocessor systems
Inventor: NISHIDA HIROSHI
IPC: G06F11/20
Filed: 2000-08-01
Abstract: PROBLEM TO BE SOLVED: To reduce resource-relative restrictions and to securely move data by temporarily interrupting service when software of a multiprocessor system is updated, as to a update system for the software of the multiprocessor system and an update system for data. SOLUTION: While the processor of 1+1 redundant constitution of in- operation and standby systems are made to operate independently, a software update part is driven for the processor of the standby state to set new-version software. While the service of the processor of the in-operation system is carried on, a processing event generated by the in-operation system is sent even to the processor of the standby state through an inter-processor communication part. Both the processors perform the same processes to reflect the control state data of the in-operation system even on the standby system gradually. When the variable control state data are all reflected on the standby system a specific time later, the processor of the standby system is switched to in- operation state.
