Title: Cache control method, acquisition control method for remote file lock, and file writing control method
Inventor: TOMITA AKI
IPC: G06F12/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve remote file input/output performance using a lock by making it possible to use a cache for a locked remote file. SOLUTION: An application 100 on a computer at a node 10 makes a request for data of a remote file on a computer at another node and when an exclusive lock is obtained for the data of the remote file at the latter node or when a common lock is obtained for the file data of a remote file which is opened in a read-only state, the computer at the node 10 which has obtained the lock holds a copy of the file data in a cache 310. When the copy of the file data is already present in the cache 310, its availability is decided and when the copy is not effective, the copy is made ineffective. When the copy is modified, the change point is reflected on the file of the copy source until the lock is released.

Title: Manufacture of needle valve
Inventor: KONKI MASAAKI
IPC: B29L31/00
Filed: 1986-07-29
Abstract: PURPOSE:To facilitate the manufacture, realize the favorable accuracy and further reduce the cost of a needle valve by a method wherein inorganic fibers are mixed in high-resistance engineering plastic, so as to expose the inorganic fibers by grinding in order to bond to fluororubber with adhesive. CONSTITUTION:To high heat-resistance engineering plastic, 5-150pts.wt. of inorganic fibers are added with respect to 100pts.wt. of resin content to injection- mold a socket 2. The inorganic fibers are exposed on the surface of the high heat-resistance engineering plastic by grinding the valve body mounting portion of the molded socket 2. After that, adhesive having functional group is coated to the valve body mounting portion, onto which fluororubber is applied under high temperature and high pressure so as to form a valve body 3 portion. Because the inorganic fibers mixed in resin are exposed by grinding the surface of the valve body mounting portion so as to be bonded to fluororubber with adhesive, the bonding of the valve body 3 to the socket 2 with adhesive becomes possible. As a result, the formation of a neck portion or a truncated cone at the valve body mounting portion becomes unnecessary and the simple and precise manufacture of a needle valve 1 becomes possible.

Title: Automatic controller for paint film thickness in producing plant for painted steel strip
Inventor: AWAI KIYOSHI
IPC: B05C11/02
Filed: 1980-12-15
Abstract: PURPOSE: To prevent the hunting of a control system by comparing the detected paint film thickness after drying with prescribed film thickness, and transmitting the signal thereof to a painting section with the delay by the time when a steel plate moves from the painting section up to a film thickness detector.  
     CONSTITUTION: In a producing plant for painted strips by painting a steel plate 1 in a painting section 3, drying the paint with a dryer 4 and taking up the plate with a take-up roll 5, the paint film thickness after drying detected with a film thickness detector 22 is compared with prescribed film thickness in a comparing operator 23. At the time of controlling film thickness by transmitting the deviation signal from said comparing operator to the section 3, the transmission of said signal is delayed by the time required for the plate 1 for moving from the section 3 to the detector 22. Since in this way the timing of control is properly matched in a long production line as well, the hunting of the control system is prevented.

IPC: G01S7/02
Filed: 1984-08-24
Abstract: PURPOSE:To output a pilot signal for AGC to a trailing stage as a signal having no correlation on the time base without suppression even when a CSLC circuit is operated in the presence of interference by making the application timing of the pilot signal or false signal different between a main and an auxiliary reception system. CONSTITUTION:A delay circuit 15 delays the AGC pilot pulse signal Vpb inputted to the auxiliary reception system 40 by time (t) with Vp. Pilot pulse signals Vpa and Vpb' which are different on the time base and have the same amplitude are inputted to directional couplers 6a and 6b in addition to a reflected signal from a body and an interference signal, and received by the main and auxiliary reception systems 30 and 40, and IF signals VM and VS are inputted to a CSLC circuit 12. When a CSLCON/OFF control signal Va is turned on in the presence of interference, the interference wave is suppressed because it has correlation. The pilot pulse signals Vpa and Vpb' on the other hand, are different on the time base and reflected signal is supplied to a trailing AGC circuit 13a without being suppressed according to the difference between antenna patterns.

Filed: 1994-07-28
Abstract: PURPOSE:To prevent the generation of a particle by providing a hollow part for circulating constant temperature fluid in a vacuum vessel to control its inner wall to desired temperature. CONSTITUTION:Constant temperature fluid such as water supplied to a hollow part 11a via a fluid leading-in hole 11b from an appropriate constant temperature fluid circulation system is discharged via a fluid discharge hole 11c. The inner wall temperature of the vacuum vessel 11 is kept lower than the sublimation temperature of an adherent film composed of a decomposition product with temperature of circulating water set to e.g. 25 deg.C, and variation is restrained. This prevents that the adherent film is separated from an inner wall due to thermal stress to become a particle. Or the temperature of circulating water is set to e.g. 80 deg.C, and the inner wall temperature of the vacuum vessel 11 is kept higher than the sublimation temperature of an adherent film. This prevents the adhesion of an adherent film to the inner wall.

Filed: 1986-07-28
Abstract: PURPOSE: To suppress a delay of specific signals, such as a clock signal and a reset signal thereby to prevent a circuit from erroneously operating by using only metal wirings to supply the specific signals to many gates in a chip. CONSTITUTION:Metal wirings are used to be wired to supply specific signals, such as a clock signal and a reset signal to many gates in a chip. The clock signal is supplied only through metal wirings A1, A2 of 2 layers in a chip having multilayer interconnection made of metal wirings A1, A2 of 2 layer and polysilicon wirings of one layer. In a chip having multilayer interconnection made of metal wirings A1, A2, A3 and polysilicon wirings of one layer, the clock signal is supplied only through the two layers of second layer metal wirings A2 and the third layer metal wirings A3, or supplied only through third metal wirings A3. Thus, the phase difference of the clock signal at the supply original of the clock signal and the many supply destinations in the chip is not almost provided, and thereby almost no possibility of erroneously operating the circuit due to the delay of the clock signal.

Title: Telephone line extending device
Inventor: TAKAHASHI RYOJI
IPC: H04M1/715
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To allow a telephone line extension use system to make extension speeches available by transmitting a signal from a caller slave set to a master set through a common transmission line and transmitting the signal to the common transmission line. SOLUTION: A CPU of an extension speech caller slave set selects a frequency of a PLL OSC and changes an output frequency of a mixer to a frequency F3. The CPU allows an output of a 20 kHz carrier generating section to be transmitted from a 3rd incoming channel in the slave set to a coaxial cable 19. An FM demodulation section 14 connected to a 2nd outgoing channel of a master set demodulates this transmission signal, a 20 kHz carrier detection section 30 detects the demodulation signal to allow a CPU 31 to select a signal changeover section 3 to a position of an extension speech. The caller slave set dials an extension number.  This dial signal is given to a channel control section of each slave set through a route of a channel control section - 2nd incoming channel (frequency F3) of the caller slave set - the 2nd outgoing channel of the master set - a 1st incoming channel (frequency F1) of the master set to ring a bell of a slave telephone set with an extension number in matching with the dial signal, resulting in making extension connection between slave sets.
